Question

His mother is ill. He has to ________ her at home.

A. look at

B. look after

C. look for

D. look into

Answer 1

B

試題分析：此題重點(diǎn)考查動詞短語辨析，look at“看”，表動作；look after“照顧、照看”相當(dāng)于take care of；look for“尋找”表示找的動作；look into“調(diào)查”,根據(jù)題意，他媽媽生病了，他必須在家照顧他媽媽，故選B
點(diǎn)評：動詞短語在考試中經(jīng)常出現(xiàn)，要正確區(qū)分并運(yùn)用，尤其是短語中的介詞是考查的重點(diǎn)。
