Qian Xuesen devoted all his life to ________________ China’s Space Program.

A.develop           B.developing         C.developed         D.develops

 

【答案】

B

【解析】

試題分析:句意:錢學(xué)森把他的一生致力于發(fā)展中國的空間事業(yè)。短語devote to致力于,本句中to是介詞,后面接名詞或者動名詞做賓語,故需B。

考點(diǎn):非謂語動詞

點(diǎn)評:不定式作句子成分表示具體的將要進(jìn)行的動作,一般不用于介詞后面。動名詞作句子成分往往表示抽象的,反復(fù)發(fā)生的動作。介詞后面一般接動名詞作賓語,也有部分動詞后接動名詞做賓語,注意和不定式作賓語表達(dá)含義的不同。
