Question

Mom asked me to _____________ grandpa when she was out.

A．look up

B．look at

C．look for

D．look after

Answer 1

D

試題分析：look up查閱；look at看；look for尋找；look after照顧，關(guān)心。句意：當她出去時，媽媽讓我照顧爺爺。故選D。
點評：解答此類題型的要點是了解各個短語的基本含義及用法的不同，同時注意其表示多個含義的現(xiàn)象，然后結(jié)合語境選擇合適答案。當人稱代詞作動詞短語賓語時，注意要放在動詞后面介詞前面。
