3．Mr．Wang told us that he would devote all the time he could spend _______ his oral English before going abroad．（　�。�
A．improveB．to improveC．improvingD．to improving

分析 王先生告訴我們，在出國前，他會(huì)把他所有能用上的時(shí)間都致力于提高英語口語水平．

解答 答案D本題中含有一個(gè)定語從句 he could spend，先行詞是time；短語devote…（time）to…是固定搭配，意為"奉獻(xiàn)…（時(shí)間）于…"，其中to是介詞，后跟動(dòng)詞時(shí)要用動(dòng)名詞形式．本題考查devote all the time to doing"花費(fèi)所有的時(shí)間做…"，故選選D．

點(diǎn)評(píng) 本題考查動(dòng)名詞在介詞后的用法．解題的關(guān)鍵是正確分析句子成分，尤其是找對(duì)定語從句和固定搭配．
