Question

---Has Jack finished painting the picture yet?
--- I’ve no idea. But he______ it the whole afternoon.

A．was painting

B．painted

C．had painted

D．have painted

Answer 1

A

試題分析：通過(guò)the whole afternoon可知，本句表示“他一直在畫(huà)畫(huà)�！笔侵傅脑谀菚r(shí)一直在做一個(gè)動(dòng)作，故應(yīng)該用過(guò)去進(jìn)行時(shí)。所以本題選A。
點(diǎn)評(píng)：在做時(shí)態(tài)題時(shí)，首先應(yīng)該掌握各種時(shí)態(tài)的結(jié)構(gòu)，另外應(yīng)該注意各種時(shí)態(tài)應(yīng)該用于的時(shí)間。本題很容易受問(wèn)句時(shí)態(tài)的影響。
