---Yes．I _____another problem just now．

A．l have thought of	B．a(chǎn)m thinking of
C．had thought of	D．was thinking of

Answer 1

D

試題分析：考查時(shí)態(tài)：根據(jù)句意：--Alice，你看起來很困惑，你懂了嗎？--是的，剛才我在考慮另外的問題。說明think of another problem是剛剛正在發(fā)生。用過去進(jìn)行時(shí)。選D
點(diǎn)評(píng)：時(shí)態(tài)的考查可以從句中出現(xiàn)的時(shí)間判斷，如果沒有就看上下文的句意，判斷動(dòng)作發(fā)生的時(shí)間。
