三组题学透
1. 非谓语动词作主语
复习要点
*熟练掌握非谓语动词作主语的用法。
单句语法填空。
(1)It takes billions of years for the light from distant stars (reach)Earth.
(陕西榆林高三四模)
答案:to reach
解析:考查非谓语动词。“It takes... to do sth.”是固定句型,意为“花费……(时间)做某事”,故填to reach,此处不定式短语为真正的主语,It为形式主语。
(2)We know that ____________(get)some fresh air can be a mood lifter, but now a German study gives us insight into why. (北京朝阳区高三二模)
答案:getting
解析:考查非谓语动词。分析句子结构可知,that引导的宾语从句缺少主语,此处表示经常性、习惯性的动作,应用动名词短语作主语,故填getting。
(3)According to the CMSA, it will become a routine for Chinese manned space missions ___________(conduct)such space lectures. (安徽淮北高三一模)
答案:to conduct
解析:考查非谓语动词。“It becomes + n. + for... to do sth.”是固定句型,意为“对……来说做某事是……”,故填to conduct,此处不定式短语为真正的主语,It为形式主语。
(4)It is worth ____________(check)if the writer of an online piece is properly qualified as an expert. (河北襄阳四中模拟)
答案:checking
解析:考查非谓语动词。It’s worth doing sth.为固定句式,意为“做某事是值得的”,其中动名词短语为真正的主语,It为形式主语,故填checking。 句意:核查一个在线作品的作者是否足够有资格当专家是值得的。
