D．may give

Answer 1

A

試題分析：考查虛擬語氣：“might have done”可以用來表示“本來有可能做某事，事實上卻沒做”，表達一種婉轉(zhuǎn)的批評或責(zé)備。本題是說“他即使很忙也可能幫助你的（但實際上卻并沒有）”。因為是談?wù)撨^去的事情，情態(tài)動詞應(yīng)與不定式的完成式連用，排除B和D。C是對過去事實的推測，與后文不符。選A.
點評：在even if, even though 所引導(dǎo)的讓步狀語從句中，可用虛擬語氣，主句、從句的結(jié)構(gòu)與if所引導(dǎo)的條件從句的各種時態(tài)、結(jié)構(gòu)相同。如： Even if he were here himself, he should not know what to do. 即是他親自來也不知該怎么辦。
