每道题都解释一下。谢谢

Answer 1

1.C 根据后面的today判断，后空用are。科学家们认为大洲并不总是在它们今天所处的位置。可以判断以前的位置与现在的位置相比。
2.C a period 是表示时间的先行词，后面的定语从句中并不缺少主语或宾语，应该缺少时间状语，应该用when =in which
3.case 在定语从句中是个特例，要用where来引导定语从句。
4..The schools themselves admit that not all children will be successful in the jobs __they are being trained. B. for which
B 表示为了工作而培训
5.D 这是分割性定语从句，先行词是the village, 定语从句中缺少地点状语，用where表示“在村庄”
6. D occasions做先行词，定语从句中不缺主语或者宾语时，要用when引导定语从句。
7. C 对于这个世界的很多城市来说，没有可以扩展的空间了纽约就是一个例子。
an example of which（which代替cities） 这样就好理解了。

Answer 2

1 C 根据解释:大陆过去不是今天样子
2 C period是一个抽象地点名词,所以用in which或where
3 A case的情况和period一样,参照第二题
4 B 是定语从句,为工作训练<be trained for jods>
5 D where 在定语从句中作状语
6我认为四个答案都不对,可能你抄错了,应该是where
7 因为世界上许多城市,那就没有空间展开进一步,纽约就是一个例子。<这题我不是很确定.选D.>
