56、iced a snake _ its way up the tree to catch its breakfast.答案：winding本题考查非谓语动词。notice后跟复合结构，宾语是a snake，宾补是wind的形式，表示当时正在进行的动作，故用winding。句意：我抬起头来注意到一条蛇蜿蜒爬到树上去捕获它的早餐。根据句意应用winding。3He claims to have seen a round black creature moving quickly through the water.他说他看见圆形黑色的东西在湖面快速潜入水中。本句使用了不定式的完成式to have s

57、een表示动作的完成。这种结构主要有下述几种方法：(1)表示该动作或状态发生在谓语动作发生的时间之前。常见于下列结构中：用作主语或宾语Its my pleasure to have attended your lecture last night.昨晚能听你的报告是我的荣幸。(主语)用于形容词后作原因状语Im sorry not to have come to your help last night.(Im sorry I didnt.)很抱歉昨晚没能来帮你。用于seem,appear,happen,chance,pretend等动词之后They seem/appear to have kn

61、ce.答案：to have brokensb./sth.is reported to do sth.为常用的表达方式，to do不能用doing形式，“打破世界记录”是已经发生的事情，故用不定式的完成式。基 础 巩 固.单词拼写1A woman was _(袭击)and robbed by a gang of youths in the street last night.2I remember that crash among the most _(令人恐惧的)experiences of my life.3 The _(生 物)of the sea provide us with rich

66、 a result of“因为”，符合句意。2He claimed to_(treat)badly in the restaurant last Sunday.答案：have been treated句意：他声称上周日在那个饭店受到了粗鲁的对待。claim“声称，断言，宣称”。其句法结构为：claim sth./claim to do sth./claim that.。由句意可知不定式的动作发生在claim之前，所以用不定式的完成时。3 There _(use to)be many people _(smoke)in the office,but now nobody is allowed t

67、o.答案：used to；smoking句意：曾经有许多人在办公室里吸烟，但是现在不允许任何人这么做。本题考查there be结构。“过 去 曾 经 有”用“There used to be.”表 示；句 型“There be someone doing sth.”中现在分词smoking作后置定语，修饰people，people和smoke之间是主动关系，故用smoking。4My assurance doesnt satisfy him;he is still _.答案：sceptical我说的确确实实，他都不信，仍有疑虑。考查词汇。sceptical“怀疑的”，符合句意。5He is l

69、分词作补语，此句中宾语sun跟宾补rising之间构成主谓关系，且宾补(rising)所表示的动作与前面seeing所表示的动作同时发生，所以应用现在分词作宾补。8Immediate action must be_(take)before it is too late.答案：takentake action to do sth.“采取措施干某事”。9 He took a taxi to the station instead of_(walk)there.答案：walkinginstead of“而不是”，后需跟n./pron./doing。10 He rarely appeared in public from then on but was _ in the news recently.答案：back考查固定搭配。be back in the news意为“再次成为新闻，再次被新闻关注”，符合题意。句意为：从那时起，他很少公开露面，但近日重新成为新闻人物。课后强化作业（点此链接）
