1.D
只有D suggest所引導(dǎo)的賓語從句才會使用虛擬語氣,即要求該從句的謂語動詞由“should + 動詞原形”構(gòu)成,且should可以省略.
即：Who do you suggest the newspaper send to cover the bank robbery?
= Who do you suggest the newspaper (should) send to cover the bank robbery?
(為便于樓主理解)= Do you suggest the newspaper (should) send (who/whom) to cover the bank robbery?
否則的話,該句子中的send都必須改成will send.
2.A
翻譯：--他完成了工作嗎?--還沒呢.盡管他整天工作,然而他還是不能完成那個任務(wù).
despite和in spite of都是介詞,不是連詞,不能引導(dǎo)狀語從句,排除CD；
B中的as意思是“因?yàn)椤?不符合轉(zhuǎn)折的句意,排除.
3.C
whether在此題中是從屬連詞,經(jīng)常和or連用,意思是“無論/不管...還是...”,不過從句最好把順序調(diào)整為：whether it is serious or minor.
如果有however的答案,則更佳.
再如：I'll go swimming whether it is cold or hot.
不管/無論天氣是冷還是熱,我都會去游泳.
4.D it
只有it可以做形式主語,代指后面真正的主語being a sailor.
5.D
翻譯：--你什么時候開始工作?
A.It’s none of your business.“和你無關(guān)/不關(guān)你事”,太過粗魯不禮貌；
B.It varies“它會變化/有不同”,句意太過突兀,不妥.
C.From 8am to 4pm.“從上午八點(diǎn)到下午四點(diǎn)”,這是工作延續(xù)的時間（段）,不是工作開始的時間（刻）.
D.it doesn't make any difference.“沒有影響/都一樣”,意即“什么時候開始工作都一樣/沒有差別”.
