1.She was halfway to the railway station ___when_____ his boyfriend caught up with her.
她在去火车站的半路上时,她的男友追上她了.
A.when B.while C.until D.though
though是转折关系,与句意不符.
until 是“直到.才.” 必须要前一个句子是否定句才可以用.
while后面接的句子里的动词要可以持续的动词.
catch up with 是瞬间动词,无法持续,因此选A.
2.___With_____ the rain falling so heavily,they couldn't go on with their drill.
雨下得太大,因此他们无法继续训练.
A.Since B.For C.As D.With
since 和 for 和 as 一样,都是要接从句的,不能接短语.
而with可以接短语,不能接从句.
从falling可以看出,第一句不完整,falling前面少了一个was.
因此第一句是个短语而不是句子,所以只能选D.
