＞＞＞Driving a car at a high speed along a highway seems to be fu..
Driving a car at a high speed along a highway seems to be fun. You need only to follow the bright traffic signs beside the highways and it will take you to where you wish. But to a London taxi driver, driving is not an easy job. A taxi driver has to have not only skills but also a good knowledge of the city of London, from the smaller road to the most popular bar around. He has to be at service of all kinds of passengers at all times. A certain London taxi driver told of his job as follows. During the night it is quite usual for him to stop two or three times for some refreshments (提神). He said, “I never drink when I’m working --- I would lose my license.” He usually goes home between 2 and 3 o’clock in the night. There are times he has to stay longer and try to make more runs. He said, “That’s the worst thing about working for yourself. If you don’t make any money, no one is going to give it to you.”
London taxi drivers not only “take” but also “give”. Every summer hundreds of children from London will go for a day at the sea --- by taxi! Their rides are paid by the taxi drivers, and these all go to the “London Taxi for Underprivileged Children”. At the sea, they are met by the mayor (市长), and a lunch party is also held in honor of the taxi drivers and the children. After a happy day running around the sea beaches and visiting the markets, the children go home again --- by taxi, and free of charge (支出), of course!小题1:From the first paragraph, we can see that________.A．highways are developing very fast and there are more and more taxis.B．it is easy to get to any place of the country nowC．it is fun to travel everywhere in a carD．the writer wants to tell us that a London taxi driver has many difficulties in his driving小题2:It is not easy to be a taxi driver in London because ________.A．he has to know all the places in the city and serve all kinds of passengers at all the timeB．there is much traffic in London and people there like traveling by taxiC．he has to follow the bright traffic sighs D．although he works hard he earns little money小题3:The underlined phrase “Underprivileged Children” in the last paragraph is about the children ________. A. who have little knowledge&&&&&&&&&&&&& B. whose families are poor C. who will go to sea&&&&&&&&&&&&&&&&&&&& C. who like taking a taxi小题4:What is the passage about?A．Traffic in London.B．London taxi for children C．Taxi divers’ job in London.D．Drivers disliking taxis in London

Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: if a star can get tossed outward at such an extreme velocity, could the same thing happen to planets? New research shows that the answer is yes.

In this artist’s conception, a runaway planet zooms through interstellar space. New research suggests that the supermassive black hole at our galaxy’s center can fling planets outward at relativistic speeds. Eventually, such worlds will escape the Milky Way and travel through the lonely intergalactic void. In this illustration, a glowing volcano on the planet’s surface hints at active plate tectonics that may keep the planet warm.

Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets?

New research shows that the answer is yes. Not only do runaway planets exist, but some of them zoom through space at a few percent of the speed of light -- up to 30 million miles per hour.
"These warp-speed planets would be some of the fastest objects in our galaxy. If you lived on one of them, you'd be in for a wild ride from the center of the galaxy to the Universe at large," said astrophysicist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics.
"Other than subatomic particles, I don't know of anything leaving our galaxy as fast as these runaway planets," added lead author Idan Ginsburg of Dartmouth College.
Such speedy worlds, called hypervelocity planets, are produced in the same way as hypervelocity stars. A double-star system wanders too close to the supermassive black hole at the galactic center. Strong gravitational forces rip the stars from each other, sending one away at high speed while the other is captured into orbit around the black hole.
For this study, the researchers simulated what would happen if each star had a planet or two orbiting nearby. They found that the star ejected outward could carry its planets along for the ride. The second star, as it's captured by the black hole, could have its planets torn away and flung into the icy blackness of interstellar space at tremendous speeds.
A typical hypervelocity planet would slingshot outward at 7 to 10 million miles per hour. However, a small fraction of them could gain much higher speeds under ideal conditions.
Current instruments can't detect a lone hypervelocity planet since they are dim, distant, and very rare. However, astronomers could spot a planet orbiting a hypervelocity star by watching for the star to dim slightly when the planet crosses its face in a transit.
For a hypervelocity star to carry a planet with it, that planet would have to be in a tight orbit. Therefore, the chances of seeing a transit would be relatively high, around 50 percent.
"With one-in-two odds of seeing a transit, if a hypervelocity star had a planet, it makes a lot of sense to watch for them," said Ginsburg.
Eventually, such worlds will escape the Milky Way and travel through the intergalactic void.
"Travel agencies advertising journeys on hypervelocity planets might appeal to particularly adventurous individuals," added Loeb.
The research will be published in the Monthly Notices of the Royal Astronomical Society, in a paper authored by Idan Ginsburg, Avi Loeb, and Gary Wegner (Dartmouth College).
