It took me a long time before I was able to fully appreciate what they __ for me.
A．had doneB．didC．would doD．were doing
A

試題分析：句意：我花費(fèi)了很長的時(shí)間才能夠完全領(lǐng)會(huì)他們?yōu)槲宜龅�。句中was able to 都發(fā)生在過去的時(shí)間，而根據(jù)句意他們?yōu)槲宜龅�，�?yīng)該已經(jīng)做完了，發(fā)生在took這個(gè)動(dòng)作之前，即過去的過去，故選A
點(diǎn)評：動(dòng)詞的時(shí)態(tài)是學(xué)習(xí)英語過程中非常重要的知識。而很多的題目，句中并沒有像本題一樣有明確的時(shí)間，很多要通過上下文的判斷得知。過去完成時(shí)表示動(dòng)作發(fā)生在過去的過去，本題不難，平時(shí)加強(qiáng)記憶，理解即可。
