中小学教育资源及组卷应用平台 Unit 5 it 作形式宾语 一．基本用法 当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时,通常会在宾语补足语前用it作形式宾语.而将真正的宾语移至句末,以平衡句子结构。其基本结构为“动词+it+宾语补足语+不定式(动名词或从句) I find it important to study English well first. 我发现先学好英语是很重要的。 I think it best not to ask him about it now. 我想现在还是不要向他询问此事为妙。 二．几种特殊的形式宾语 通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形。即用于动词+it+宾语补足语+真正的宾语”这样的结构,但以下几类形式宾语却比较特殊,其后没有宾语补足语。 (1)动词+it+that从句 I take it that you disagree with me.我的理解是，你和我的见解有分歧。 You can put it that it was arranged before.你可以说这是以前安排好的。 能用于此结构的动词不多,常见的有have,take,put, like 等。 (2)动词+it+when(if)从句 I dislike it when people speak with their mouth full of food. 我不喜欢人们满嘴含着食物说话。 I'd appreciate it if you can contact me as soon as possible. 如果你能尽快联系我，我会很感激。 能用于此结构的动词不多，常见的有enjoy, hate, love, like, dislike, appreciate, prefer 等。 (3)动词+介词+it+that从句 Please see to it that the quality of the product is maintained. 请务必保持产品的质量。 I only rely on it that he can tell me the fact. 我仅能依靠的是他能告诉我事实真相。 能用于此结构的动词不多,常见的有see(to),look(to) insist (on), stick (to),depend/rely (on),answer (for)等. (4)动词+it+介词短语+that从句 I owe it to you that I can get so much progress. 我能取得那么大的进步该归功于你。 I just took it for granted that he'd always be around. 我还想当然地以为他总能随叫随到呢。 能用于此结构的动词不多，常见的有take(it for granted) bring (it to one' s attention),owe (it to sb.)等。 难点1： 否定词置于句首引起的部分倒装 教材例句 Nor would they fail to imagine how its native inhabitants, including royal penguins, king penguins, and elephant seals, existed in perfect harmony with their natural habitat for thousands of years. 他们也不难想象出，数千年来,包括帝企鹅、王企鹅和象海豹在内的当地动物是如何与其自然栖息地完美地和谐共存的。 否定词 nor 位于句首,句子用部分倒装。其结构为:nor+助动词/情态动词/be动词+主语+主要谓语动词+其他成分。 当含有否定意义的词或短语置于句首时,句子须用部分倒装,即把助动词、情态动词、be动词移至主语之前。这样的词或短语有never,neither,nor, not, seldom, little,hardly, rarely, scarcely, at no time, by no means, in no way 等。 Never have I seen such an amazing performance. 我从没见过如此惊人的表演。 In no way shall I give up. 我决不放弃。 “nor/neither+助动词/情态动词/be动词+主语”意为“……也不……”表示前面的否定情况也适用于另一人或物。 If he doesn’t go to the park tomorrow, neither/nor will I. 如果明天他不去公园,我也不去。 either... or..., neither... nor... 连接并列主语时，谓语动词的数取决于or或 nor 后面的主语的数。 难点2： 主语(表无生命的事物)+ see/find/witness+宾语 经历/发生/见证/目睹了 教材例句 Recent years have seen more and more pet sliders escaping or being released from homes, and some owners beli ... ...
