1、 Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．Components of SoftSoil is made up of a number of layers（层），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2.000 years ag0．Water Beneath the SoilSurface water collects and flows above the ground in lakes．ponds．and rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（渗透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.Soil pHSoil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rockfrom which it was formed．and by the nature of t}le plants that grow and rot in it．The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．1、The layer of soil that provides necessary nutrients for plant growth is called．A．1itterB．topsoilC．humusD．subsoil2、According to the text．which of the following is NOT true?A．Soil forms from weathered rock on the earth surface．B．The deeper layer of soil is darker in colour than t}le surface soil．C．Air pollution is partially responsible for acid soil．D．Groundwater tends to carry away nutrients for plant growth．3、We can infer from the passage that the water table lies ．A．between the topsoil layer and the subsoil layerB．in the subsoil layer above bedrockC．between the subsoil layer and bedrockD．in the bedrock layer beneath the subsoil4、The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ．A．rushed away into the riverB．cleaned and purified by waterC．destroyed and carried away by waterD．mixed with water and become part of it

3、 When Jackie Robinson walked onto Ebbets Field in Brooklyn, New York, on April 15, 1947, he changed baseball forever. As the first African American to play in the Major League in modern times, many believe he changed the country forever.Robinson was born in 1919. He lived in a time when rules controlled what African Americans could do. He was a top athlete, playing football, basketball and baseball. But playing for a major League team was off limits to Robinson because of his race. Branch Rickey, president and manager of the Brooklyn Dodgers, signed (和……签约) Robinson in 1947. He believed that Robinson not only had the skills, but the courage to face the challenge of becoming modern baseball’s first black player.It wasn’t easy. Robinson sometimes faced boos (嘘声) from fans. But he became a star, anyway. In 1962, he became the first African-American player chosen to enter the Baseball Hall of Fame. In 2005, he was awarded a Congressional Gold Medal, the highest award Congress can give to an American.By breaking baseball’s color barrier (肤色障碍), Robinson opened the door for many to follow his footsteps, not only in baseball, but in other areas of life as well.

4、 Pingyao, in the center of Shanxi Province, is a famous historic cultural city of China and a world cultural heritage site (世界文化遗址). It’s 90 kilometers south of Taiyuan on the Fen River.People lived in Pingyao during the New Stone Age. Its long period as a country government seat has left Pingyao with lots of historic buildings and sites, with a 2,700-year history. Ninety-nine of them are under government protection, including Zhengguo Temple, Shuanglin Temple and Pingyao Ancient City.During the Ming and Qing Dynasties, businessmen organized commercial (商业的) groups that did business nationwide. Shanxi Province had some of the most important ones and Pingyao was their center. In 1823, a store, known as Rishengchang(Sunrise Prosperity), traded in bank checks rather than in silver or gold coins. It was the beginning of modern Chinese banking. Branch banks were soon set up in major cities in China and other parts of Asia, leading to great development in Pingyao. Its Lacquer ware (漆器) became well known.In Pingyao Ancient City are many traditional houses and commercial buildings, 3,797 of which are protected and more than 400 of which are in good condition. Not only do the houses in Pingyao show Shanxi’s history and culture, but this large number is valuable for studying its history, customs, and ancient buildings and art.

9、 There is an old saying in English： "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing； it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which tolerated the pain for the longest time was 'the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins （内啡肽） in the brain. These are natural chemicals which diminish both stress and pain.There is also some evidence to suggest that laughter helps the body's immune(免疫的)system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group served as the control group - in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.As a result of these discoveries, some doctors and psychiatrists （精神病学家） in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.1、 We learn from the first paragraph that laughter____________________. A．is good for one's healthB．is related to some illnessC．has been investigated long sinceD．has no effect on the body2、Doctors have found that laughter_______________________. A．keeps down blood pressure.B．has similar effects to physical exerciseC．decreases the heart rateD．increases stress3、Which of the following statements is NOT true of laughter, according to the passage?A．It reduces pain. B．It exercises the body. C．It improves the body's immune system. D．It can cure cancer.4、The writer's attitude towards laughter is__________. A．criticalB．doubtfulC．positiveD．negative
10、 Reduce, reuse, and recycle. This familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways. The concept is being used to deal with one possibly dangerous form of waste — electronic junk (电子垃圾), such as old computers, cell phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.“A lot of these materials are being sent to developing nations under the excuse of reuse — to bridge the digital divide,” said Richard Gutierrez, a policy researcher.One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial is finally beginning to take the lead.1、 The passage mainly tells us that _______.A．developing countries are facing serious environmental problemsB．e-waste is sent to developing countries under the excuse of reuseC．developing countries are making full use of e-wasteD．e-waste is a growing problem in developed countries2、What does the third paragraph mainly discuss?A．A lot of e-waste is dumped in developing countries.B．Poor people break up e-waste to collect some valuable materials. C．The problem of e-waste is growing in developing countries.D．Old computers and TVs still work before they are sent abroad.3、The underlined word “unscrupulous” in Paragraph 1 probably means “________”.A．immoralB．wrongC．proudD．unsafe4、From what Gutierrez said we can learn that ________.A．developing countries should be responsible for this problemB．exporting countries should be mainly responsible for this problemC．neither rich nor poor countries should be blamed for this problemD．poor countries should be blamed for this problem
11、 Preparing for the Next Job MarketThe latest spike in the unemployment rate is being felt across the board ?in 98 percent of metropolitan areas, in high-wage and low-wage jobs, among young and old, women and men, but especially men．This landscape means that young Americans who are trying to plan their futures right now have some hard choices．Do they go to college and take on debt without hope of getting a job? And what about high school students? Do they have any chance of securing a job without a college degree? Perhaps the education system needs to react to this rapidly moving economic crisis．In our current economic collapse, the connection between education and employment could not be more different than it was during the Depression．Education must now hold center stage, not because of an enemy abroad but because of the global economy．The jobs of the future will demand levels of education, particularly skills in mathematics, technology and science, which exceed those now taught in high school．A healthy society should strive for full employment．In our times, that goal cannot be realized, or even approximated by creating jobs for the unskilled．The long-term prospect for economic recovery depends on the extent to which we improve our educational system．And this is where America is now at its weakest．##Our high schools produce graduates who do not write well enough, have limited reasoning skills and are unable to use the tools of mathematics．Their command of science is far inferior to that of their counterparts in other nations．And all too many young people drop out．We may still have the best university system, but it benefits only a minority．We will need more engineers, scientists and service providers, particularly in the health professions, with a quality of education that cannot be obtained in the current system．Radical change, not reform, is called for．What should be done? First, high school should be cut short and end when students are 16．Second, a new generation of two-year college programs tied to a wide range of specific skills that the economy needs should be created．Third, access to four-year colleges should be expanded, giving more Americans the chance to acquire the deep learning that makes breakthroughs in technology possible．Fourth, we need to recruit more public school teachers and train them better, particularly in physics, chemistry, biology and mathematics, so that our children can be prepared to compete．1、Nowadays, students graduating from high school____．A．write well enoughB．have limitless reasoning skillsC．can't use the tools of mathematicsD．command science as much as their counterparts in other nations2、What should we do to improve the quality of education?A．Students shouldn't study in high school until 16．B．We should create a new generation of two-year college programs tied to a wide range of specific skills the economy needs．C．We should limit access to four-year colleges．D．We ought to recruit more private school teachers and train them better．3、What does the word "collapse" in the third paragraph mean?A．successB．failureC．developmentD．booming4、Which of the following is NOT true according to the passage?A．Young Americans planning their futures have difficult choices．B．Education must hold center stage due to the global economy．C．The best university system benefits a majority．D．A health society should struggle for full employment．
12、 The food we eat seems to have great effects on our health. Although science has made great steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to diet as well. Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates(硝酸盐) and nitrites(亚硝酸盐), commonly used to keep color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels(标签) of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to cows and chick and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the FDA has tried repeatedly to control these, the practices continue.1、How has science done a bad service to mankind?A．Diseases caused by food have been done away with.B．It has caused a lack of information about the value of food.C．Some harmful materials have been added to our food.D．Scientists have made food more expensive to eat.2、What are nitrates used for?A．They help process packaged food.B．They keep the color in meats.C．They cure diseases of cows and chickens. D．They cause the animals to become fatter.3、Which of the following statements is NOT true?A．You can find out harmful additives on the packaging labels of food.B．Drugs given to animals are not all for medical reasons.C．Researchers knew about the harm of food additives about 60 years ago.D．Food may cause forty percent of cancer in the world.4、According to the passage, the FDA might be _________.A．an organization which controls the safety of food B．a producer which makes additivesC．a factory which processes foodD．a hospital which cures cancer
13、 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。During the first half of the nineteenth century in the United States, Christmas was a very different kind of holiday than it is today. There was no set of way of celebrating the day,which was not yet an official holiday.
71 Some observed Christmas as an important Christian religious day honoring the birth of Jesus.Others celebrated the day with parties,music,drinking and eating.
.Calvinist Christians banned the celebration of Christmas.But groups such as Episcopaliansand Moravians honored the day with religious services and seasonal decorations.By mid-century,Christian groups began to ignore their religious diffrences over the meaning of Christmas and honored the day in special ways.Christmas became an important time for families to celebrate at home. More and more Christians Americans also began to follow the European traditions of Christmas trees and giving gifts.Christians believed that the tree represented Jesus and was also a sign of new beginnings. German immigrants brought their tradion of putting lights,sweets and toys on the branches of evergreen trees placed in their homes.This tradition of setting up a Christmas tree soon spread to many American homes.
74 As these traditions increased in popularity,the modern trade and business linked to Christmas also grew.As Christmas became more popular,some states declared the day a state holiday.Louisiana was the first state to make the move in eighteen thirty-seven.
.It was not until eighteen seventy that President Ulysses Grant made Christmas a federal holiday.A．So did the practice of giving people presents.B．By eighteen sixty,fourteen other states had followed.C．And,some communities did not celebrate the day at all.D．Americans seldom gave each other presents on Christmas Day.E. But many new American Christmas songs started to become popular.F. Religion played a big role in how an American might celebrate the holiday.G. Communities around the country honored the day in different ways.

15、 There was such a long queue for fried chicken at KFC that we_____ gave up. A．eventuallyB．unfortunatelyC．generouslyD．purposely
16、 In Europe people hold the fork in the left hand and the knife in the right throughout the meal, a system that is generally agreed to be more efficient than the American zigzag（曲折的）method. Americans hold both the fork and the knife in their right hands throughout the meal, so they continually change their forks to the left hand when they have to cut their meat. It seems to be funny for the Europeans to see Americans busy changing their dinner sets, making a lot of noises. A few explanations for this American style are as follows:(1)Americans are practical and efficient. Since most of us are right-handed, it is reasonable to keep our working tools at all times in the right hand that can use them most efficiently.?(2)Americans, the master of the New World are rebels（叛逆者）.They use the zigzag method to break the rules in the Old World and in this way they are thumbing their nose at Mother England. Americans are a restless kind. They do not like to sit in one spot for very long when dining.(3)Forced to do so, they respond by “playing” with the silver.?Whatever the reason for the practice, it is now certainly as American as apple pie. Europeans recognize this and are quick to attack it as evidence of American innocence（无知）of form. Arguments against the zigzag method rest not only on grounds of efficiency but also on those of tradition. In Old World dining, the knife is held in the right hand continually because it can serve as an instant defense against the uninvited intruders（入侵者）.However, such alertness（警觉） is out of place in the New World, as every American believes that this is the home of the brave. Americans juggle their silverware, perhaps, to show that they are not afraid and that one of them holding a fork is worth any number of them holding blades（刀）.?1、Americans use _______ to hold their fork to pick up the salad.?A．the right handB．the left hand?C．both handsD．either of the two hands?2、As the masters of the New World, Americans use a different cutting method from that in the Old World to _______.?A．show their independence of Mother England?B．show their disrespect to Mother England?C．add a new tradition to those in Mother England?D．show off their creativeness to Mother England?3、In the sentence, the word “juggle” probably means _______.?A．holdB．play withC．pick upD．lay down??4、Which of the following statements is NOT true? ?A．European people hold the fork in the left hand and the knife in the right hand.B．The zigzag eating method is related to American characteristics.?C．The zigzag eating method has become an American feature.?D．European people will use the American method because of its efficiency.
