2、 man (that/who/whom) you visited last night is my grandpa. 我不喜欢你对待这个女孩的方式。I dont like the way (in which/that) you treat the girl.二、虚拟语气中if及should的省略1. 当条件状语从句中有were, had, should等时省略if，把它们提至句首，形成倒装句。e.g. If I were a teacher, I would be strict with my students. = Were I a teacher, I would be strict wi
3、th my students.2. Suggest, insist, order, require等表示建议、要求、命令的动词后接的名词性从句中，谓语动词常用“should+动词原形”, should可以省略。e.g. 医生建议他尽力去减肥。The doctor suggested that he (should) try to lose weight.三、So和not的替代性省略用于避免重复前面所说过的内容，替代词so/not替代肯定或否定的名词性从句。可与believe, do, expect, fear, guess, hope, say, speak, suppose, think,
4、Im afraid等连用e.g. Do you suppose he is going to attend the meeting? I suppose not. Can you finish your work today? 我认为能。I think so . 我认为不能。I dont think so . / I think not . 四、日常交际中的省略在情景会话中，答语常常省略不会引起歧义的主语、谓语或宾语部分，而只保留对方希望了解的内容。在复合句或并列句中，也有省略主、谓、宾的情况。e.g. How many copies do you want? - (I want) Three
5、 copies, please. - Have you ever been to the Great Wall? - No, (I have) never (been to the Great Wall).注意：1. 感官动词see, hear, feel, watch等和使役动词have, make, let等后接不定式作宾语时，不定式省略to。2. do nothing but, cant help but等结构常接省略to的不定式。e.g. 我们昨天只是仅仅呆在家里看电视了。We didnt do anything but stay at home watching TV yesterday. 听到这个消息，她禁不住哭了。 Hearing the news, she couldnt help but cry.3. 在特定语境中为了避免重复，当不定式再次出现时，在want, wish, hope, try, plan, like, love, hate后往往只保留to，而省略后面的动词。但不定式后有be, have时，也保留be和have。e.g. My parents encouraged me to go to college, （但是我不想去）but I didnt want to.
