試題分析:suggest后的從句用虛擬語氣,should+do,should可省略。指advise, suggest, propose, recommend,demand, require, request等后的賓語從句,從句謂語由“should+動詞原形”構(gòu)成,其中的should在美國英語中通?梢允÷
點評:本題難度適中。虛擬語氣是高考?嫉膬(nèi)容,需要考生熟記它們的各種情況,多記多練,還必須會分析理解句子的成分。
即學(xué)即練:It is strongly recommended that the machines____ every year.
A. check        B. should be checked       C. checked     D. shouldcheck
