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(dāng)她出去時(shí)，媽媽讓我照顧爺爺。故選D。
點(diǎn)評(píng)：解答此類(lèi)題型的要點(diǎn)是了解各個(gè)短語(yǔ)的基本含義及用法的不同，同時(shí)注意其表示多個(gè)含義的現(xiàn)象，然后結(jié)合語(yǔ)境選擇合適答案。當(dāng)人稱(chēng)代詞作動(dòng)詞短語(yǔ)賓語(yǔ)時(shí)，注意要放在動(dòng)詞后面介詞前面。
