4.Jane sat at the table with the gold watch chain in her hand ,___ to meet her husband .
A.eager B.was eager C.to be eager D.being eager
5.Scientists are concentrating on antiviral drugs already in drugstores ,__ something that will quickly help people stop dying from the new disease.
A.hoping to find B.to hope to find
C.if to find D.whether finding
4.A 5.A
两题有什么区别?为什么两题都不能选其它选项?
1.A
用形容词表示状态,如果选B的话,要加上一个and(was eager).C.to be eager 要翻译成“为了渴望”,那么句子前半段的意思就不对了,可以这样改,to be eager to meet her nusband,Jane telephoned him.这样改动太大,也没有必要.如果选D,就要翻译成“正在渴望着”,不符合题意.
2.A
这是一道分词做状语.
逗号前面的主语是scientists,逗号后面没有主语,那么只能考虑,scientists 和hope 的关系,很明显是主动关系,所以选hoping to do
