B (因为回答里面有have,意思是“每个学生都很努力学习,都已经读完那本书。 我也是&)C (因为后面是表示真理性的,)A(强调对现在的影响,所以用现在完成时)B(“你为什么没去参加会议”,“我当时正在等我姑姑从美国打来的长途电话”,now是指昨天开会的时间,所以用过去进行时)B(前句为虚拟语气,后句为现实情况,用过去式即可)

All fights_____because of the snowstorm,many passengers could do mothing but take the train.A.had been canceledB,have been canceledC.were canceledD.having been canceled____what would happen,none of them could find a way outA.Left wondering B.Having left wonderingC.Leaving to wonderD.Having left to wonder解释一下
提问者采纳
一个句子只能有一个谓语动词,后句已经有动词could do,所以前句必须是非谓语结构,这样就能判断选D了,本来是All fights have been canceled的,变为非谓语就是have 变为 having了;2、A 同样是考查非谓语的题目,还原一下就是 All were left wondering what would happen,and none of them could find a way out!这是完整的一句话。现在没有and,后句有谓语find,所以前句是非谓语,前句、后句主语都是them,去掉前句的主谓 all were,就是A啦!
希望你能懂~~!

航空不是自己取消是人来取消 ,所以被动的,另外这个是已经被取消不是过去被取消, 所以 用完成时 A
D 此处需用非谓语,因为逗号后无连词,故其它选项都错(因为它们都是正常的谓语动词);A 考查非谓语,首先主句的主语与leave间是被动(此处leave非离开之意)故用过去分词left,与wonder为主动关系,故用ing形式。

我可以明确地告诉你,once begun, nothing can be done to stop it ,至少是 once begun,在语法上是错误的表达,(这可能是以前的高考英语句子)。once begun 是分词结构还是独立主格结构? 如果是分词结构,,begun的逻辑主语就是nothing,而不是the research。 如果是独立主格结构,应该有逻辑主语,但这里没有。所以,正确的表达是:The research is so designed that once it (== the research )is begun, nothing can be done to stop it . -------应该用时间状语从句来表达。 你应该快高考了吧?相信你也有这样的分析能力。不然,你就问一下你的老师。 2
如果按照“分词结构”的原理来分析,BCD都是正确的答案,因为这里已经不考虑“主动”或“被动”了--------因为begin是及物动词,也是不及物动词。肯定一个而否定另一个都是错误的做法。 3
语感告诉我,这样的句子是败笔,出得太烂。

这里once表示虚拟,后面接一般过去式。once it begun, nothing can be done to change it.
完整的是 once the research is begun.
条件句与主句的主语和谓语一致时,可以省略,因此只填begun。

最佳知识点讲解
知识点相关讲解
1 .第一个句子自己能理解啊,不好说啊
2. 非限制定语从句啊
3.it is +n 或adj that 句型
4.根据句子意思,用排除法
5.前句说早上我没有看见她在会议上,后句说就能肯定她不可能在会议上了,用的couldn't have done 不可能什么
6.不是很清楚啊
—— nytimeshcy
1 他们看你有几分像个杞人忧天的家伙,总是担心一些不存在的问题并且想通之前要绕很多弯。
你看crossing 和 seeing 并列就知道为什么选C了
2 非限制性定语从句,形容前面的行为
这句话很怪,不过如果你确定没搞错的话应该是这个意思:我无法形容我的regret(遗憾、惋惜或悔恨,联系语境和上下文)。很遗憾这起交通事故本来会发生的。言下之意是,这起交通事故本来要发生了,幸亏没发生,要不然更糟,我对之前的种种问题(就是使交通事故可能发生的问题)表示遗憾。
4 stay within call是随叫随到的意思
5 couldn't have done是不可能如何如何,表示否定推测,must have done一般不用否定
6 A和D不对我也说不上为什么,当然我觉得是读不通的,我帮你问问别人。the amount of 常用不可数名词
—— augustusjk
1.独立主格,主语是you,用主动态,加之后面有and 可参考crossing,选c
他们觉得你杞人忧天、脑筋转不过弯,老是担心不必要的事。
2.非限定性从句,如果用as,没有主语
3.should在这里的意思是竟然,完成时表示已经发生的事
我不知道怎么表达我的惋惜。车祸竟然发生了,这的确是令人感到非常遗憾的事
4.within call是固定词组,随叫随到的
5.对过去的猜测只能用could,could have done 表示对过去的猜测
6.A:as two times as many
B:the amount of +不可数名词  C: double 做动词  D错得太离谱,谁出的题啊
