有关it的几道易错题

有关it的几道易错题 1. Everyone knows that _ is dangerous to play with fire, but _ is difficult is to prevent children from playing with fire. A. it, it B. what, what C. it, what D. what, it 【陷阱】很容易误选B，认为两空均考查形式主语。 【分析】答案是D，第一空填形式主语，真正的主语是其后的不定式 to play with fire。第二空填 what，what is difficult 是主语从句，注意 what is difficult 后的谓语动词 is。请做以下类似试题： (1) I know _ is important to know my own limitations, but _ is difficult is to help others to know their own limitations. A. it, it B. what, what C. it, what D. what, it (2) Yes, _ is difficult to find a job nowadays, but _ is more difficult is try to find such a job with a high salary but little things to do. A. it, it B. what, what C. it, what D. what, it 2. I dislike _ when others laugh at me in public or think poorly of me behind. A. that B. those C. it D. them 【陷阱】几个干扰项均有可能误选。 【分析】答案是C，因为在通常情况下，like 是及物动词，其后应有宾语(句中 it 即为其宾语)。句中的 when 从句不是宾语从句，而是时间状语从句，其中的 when 的意思是“当的时候”。其实，也有的词典将 I dont like it when (if) 作为一个句型来处理。能这样用的动词不多，主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示喜好的动词。 She wont like it if you arrive late. 她不喜欢你迟到。 He hates it when people use his bike. 他讨厌别人用他的自行车。 请做以下类似试题(答案均选 it)： (1) I hate _ if people say such things in public. A. that B. those C. it D. them (2) Id prefer _ if I didnt have to get up early on Sundays. A. that B. such C. it D. which (3) I would appreciate _ very much if you could give me some suggestions. A. this B. that C. it D. you 3. Ive no idea. I just pretended nobody was at home, so I didnt ask who _ was. A. he B. that C. she D. it 【陷阱】容易误选A或C。 【分析】答案是D。it 用以指身份不明的人。若指身份明确的人，则不宜用it。比较： (1) Mr Smith is at the door. _ wants to see you. (2) Someone is at the door. _ must be Mr Smith. A. He B. It C. This D. That 第(1)题选A，因为来者身份明确；第(2)选B，因为来者身份不明确。 4. Will you see to _ that my children are taken good care of while I am away? A. it B. me C. yourself D. them 【陷阱】几个干扰项均有可能误选。 【分析】答案是A。it 为形式宾语，真正的宾语是空格后that引导的宾语从句。see to 意为“负责”、“注意”，其中的 to 为介词，不宜直接跟that引导的宾语从句，遇此情况可借助代词 it。请做下面两题，答案也是选 it： (1) Ill see to _ that all these letters will be sent to the post before twelve. A. it B. me C. which D. them (2) Will you see to _ that the luggage is brought back as soon as possible? A. me B. yourself C. it D. them 类似以上 see to 用法的短语还有 depend on, answer for 等。如下面两题答案也选 it： (1) You may depend on _ that he will t
