Question

With so much noise outside, the students can’t _____ their homework.

A．concentrate on

B．depend on

C．keep on

D．put their hands on

Answer 1

A

試題分析：重點(diǎn)理解句意，掌握四個(gè)選項(xiàng)的區(qū)別concentrate on集中精力于某事 depend on依靠 keep on 繼續(xù)put their hands on找到；把手放到什么上面  整個(gè)句意為：伴隨著外面巨大的噪音，學(xué)生們不能集中精力于他們的功課上。故選A。
點(diǎn)評(píng)：本題不難，理解了句意后不難得出答案。平時(shí)的復(fù)習(xí)，要多對(duì)動(dòng)詞的短語(yǔ)進(jìn)行積累、記憶，同時(shí)最好能在作文運(yùn)用出來(lái)，這樣就能做到學(xué)以致用了。
