中学英语语法精典总结 1.sometimes/some times/sometime/some time: sometimes: “有时”=at times. He is sometimes late for school. some times: “几次”I have been to Nanjing some times. sometime: “某一时刻”I bought it sometime last spring. some time: “一段时间”We have to stay here for some time. 2.need 的用法：1.need可当情态动词（和can等用法类似，但need只用于疑问句或否定句中）：Need I go now? (need 在一般疑问句的开头) I needn’t tell you the answer. (否定句中直接在need后加not) 【当情态动词时，need无时态变化。】 need 可当行为动词（和want 等用法类似）： He needs a bike. (后可直接加名词) I need to go over my lessons. (后接带to不定式) Do you need to have a rest? （一般疑问句中do, does, did在句首） We don’t need to wait for her coming. (否定句中do,does,did提前) 【注：need 后接表被动的内容时，可表达为： The TV needs to be repaired. = The TV needs repairing.】 3.do with 与deal with: 都译为“处理，对付，安排，应付” What have you done with the milk? 用what提问。 How shall we deal with this problem? 用how提问。 下面两句由此而来：Could you tell me what to do with the milk? Could you tell me how to deal with this problem?4.就近原则：常见的有：Either you or Lucyis wrong. There is a dog and two cats in the yard. (there be句型) Not only you but (also) Iam strict in the work. Neither you nor Lucy has seen the film before. 5.主谓一致：One/Neither of you is right. （单数谓语） Tom, with his friends, has gone. (主语是Tom, 单数谓语) This pair of shoes looks beautiful. （主语是pair, 单数谓语） The shoes look beautiful. （主语无pair, 复数谓语） Every boy and every girl has a chance to do it. （单数谓语） The old need to be looked after carefully. The young are energetic. (the 加形容词表一类人，谓语用复数) Mr. and Mrs Green are from America. 指格林夫妇 (复数谓语) The teacher and writer is an able man.指教师兼作家, 一个人，单数谓语。 Both you and I are excited about the news. （复数谓语） the number of与a number of6.quite/such/really用法之一：如果出现不定冠词时，常放在后面。 It’s quite an easy question.

What day is it today? What’s the date today? What’s the price of this one? 8.there be部分用法：1There is only a student taking notes now. There is no need to open the box. There are 20 trees to be planted. 2常有以下结构: there may/will/must/is going to/used to/…be. … 3there be中不可再出现have/has/had(有)的词。 9.常见表否定的词或短语:no, not, hardly, few, little, neither, nor, nothing, nobody, none, nowhere等. 有些有时在某些句型中也相当于否定，如without, too…to… without anything, too tired to go any further 但前缀如dis--, un--, in--或后缀如--less,并不表否定。 10.常见后接动词原形的词或短语: why not / had better / please /would you please / let / make / 情态动词，等等。【注意否定形式：had better/ would you please/ let直接加not + 动原；而please加don’t+动原】 11.常见后接动词ing的词或短语：finish /enjoy /practice /give up / end up /put off /consider /keep /feel like /prefer…to…/can’t help / be busy /be worth /take turns /miss(错过) /spend /have fun /介词等。 12.常见后接带to不定式的词或短语：want /hope /wish /allow /encourage /ask /tell /pretend /decide /plan/invite /urge/ advise/warn/ seem /in order (为了) /疑问词，等等。 另外it作形式主语，后也常有带to不定式。 【否定：以上大多词 + not + to do sth】 13.被动语态(be +v.过去分词)用法：I did it. →It was done. 双宾:He told us a story.→We were told a story.→A story was told to us.

B: I’m sorry to hear that. 3one 指代上文所说的某类可数名词单数，但不是同一个物。This sweater is too expensive, do you have another one?(也指毛衣，但不是上文那个) 17.at/by the end of, in the end 的区别： 1at the end of +时间点或地点，“在…的尽头，在…的末尾” They will have a sports meeting at the end of March. (加时间) He put some books at the end of the bed. (加地点) 2by the end of +时间点，“截止到…末” 若接过去的时间点，常用过去完成时：They had planted six thousand trees by the end of last month. 若接将来的时间，常用一般将来时：We shall finish the work by the end of next month. 3in the end “最后”，后不加of 短语：They wanted to find a place to rest in, in the end, they saw a village. 18.have gone to/have been to/have been in: 1have gone to+地点“已去了…（还未回来）”-I can’t find those children, where are they? -They have gone to the farm.

She feels a bit / a little tired. 也可作代词或形容词，后接名词时有所不同： I have only a little drink. She ate a little bread and went out. (a little 直接加名词) 而下文：I have only a bit of drink. She ate a bit of bread and went out. (a bit 先加of再加名词) 21.“擅长”与“不擅长”; “对…有利”与“对…有害”： “擅长”：be good at / do well in “不擅长”：be bad in / be poor in / be weak in / do badly in “对…有利”：be good for “对…有害”：be bad for 22. 表数量的词和短语的部分用法：1none / all / some / most / plenty of / a lot of (lots of) 后既可接可数名词复数，也可接不可数名词。2many / (a) few / a number of / several只接可数名词复数。3much / (a) little / a bit of只接不可数名词。 23.易用错的副词：1really可修饰动词、副词和形容词，常在它们前面。I really love reading.

I am very happy. Peter speaks very slowly. (very不可修饰动词：I very like English.

What bad weather! I bought a new bike. 形容词可在系动词后，作表语(划线部分)： The girl is kind. His face turned red. It tastes sweet. 2副词(划线部分)修饰动词、形容词、副词，也可修饰整个句子。 He ran quickly. Please speak loudly. Tim lives alone. 修饰动词 She is very angry. He felt too tired. I’m so lucky. 修饰形容词 He got up quite early. She did it very well. 修饰副词 Unluckily, I failed the English exam. 修饰整个句子26.everyday与every day: everyday是形容词，后接名词，“日常的”。He is practicing everyday English. every day是副词，作时间状语，“每天”。We speak English every day.
