1.從句意可以看出,C無疑是最準(zhǔn)確的答案.
be eager for sth 渴望/渴求/爭取...,指“以巨大的熱情渴望實(shí)現(xiàn)愿望或達(dá)到目的
be enthusiastic for/about sth.對某事熱心
be keen on/about sth 喜歡/喜愛...
be anxious for 渴望有(得到),指“熱切地希望實(shí)現(xiàn)愿望,并因顧慮愿望落空而心情不安,感到焦慮的”
2.此題考察not...until..句型的倒裝用法,所以我們必須先還原該句:
John couldn't go to school until his father was out of prison.
再倒裝成:Not until his father was out of prison could John go to school.
所以我認(rèn)為答案是C而不是A.
我認(rèn)為樓主可能抄錯題目,如果要選A,那么原題應(yīng)該是:
It's not until his father was out of prison ____A___ to school.
a.that John could go
那么這考查的就是not...until...的強(qiáng)調(diào)句型了:
It's not until+某個時刻/從句+that+主句的肯定變化句式.
3.樓主應(yīng)該又少抄了點(diǎn)什么.如果非要選C的話,那么在橫線和I could't go on with my work之間加上一個that.
則此題考查的是so/such...that...的倒裝句型了:
當(dāng)“so/such ...that ...”結(jié)構(gòu)中的so,such連同它所直接修飾的成分共同位于句首表示強(qiáng)調(diào)時,主句要進(jìn)行部分倒裝(that后面的結(jié)果狀語從句不倒裝).
如：So fast does he run that he is far ahead of others.他跑得如此快,以至于遠(yuǎn)遠(yuǎn)領(lǐng)先于其他人.
再如:To such an extent do the parents love their son that they have tried to satisfy every demand of his.父母倆愛子愛到了如此程度,以至于盡量滿足他的任何要求.
