1、精选优质文档-倾情为你奉上七年级下册仁爱英语语法一，there be1. there be句型（一） (1)句型结构为：there be(is/are)+某物某人+地点时间（介词短语），意为“某处某地有某人或某物”，表示存在的一种状态，句中be动词的选择由其后面的名词确定有两种句式： There is+单数名词不可数名词+介词短语：如： There is a computer in the study 书房里有一台电脑。 There is some water in the bottle 瓶子里有一些水。 There are+名词复数形式+介词短语。如： There are some flow

2、ers in the garden 花园里有一些花。 be动词后面的名词如果是由and连接的几个名词时be动词应遵循就近原则，即与邻近名词的数保持一致。 There is a chair and two desks in the teachers room. 老师的房间里有一把椅子和两张桌子。 There are two desks and a chair in the teachers room. 老师的房间里有两张桌子和一把椅子。 (2)there be结构的否定句： there be结构的否定句直接在be动词后面加not。如： There is an apple on the plate

3、盘子里有一个苹果。 There isnt an apple on the plate盘子里没有苹果。(3)there be结构的一般疑问句及肯定、否定回答： there be结构的疑问形式直接把be动词提前，句末加问号。 肯定回答：Yes，there is/are. 否定回答：No，there isnt/arent . -Are there any books about Chinese history? 有关于中国历史的书吗？ -Yes.there are./No,there arent 是的，有。不，没有。 -Is there a computer in your study? 你的书房有

4、电脑吗？ -Yes,there is，/No，there isnt 是的，有。不，没有。2. there be句型（二）(1)针对there be结构的名词提问，常常用whats+地点状语，名词无论是单数形式还是复数形式，be动词都用is，且常省略there。如： There is a desk in the room. （对画线部分提问） 房间里有张桌子。 Whats in the room? 房间里面有什么？ There are many students in the class room（对画线部分提问） 教室里有许多学生。 Whats in the classroom教室里面有什么？

5、(2)针对there be结构中名词的数量提同，用how many或how much提问，后面要紧跟这个名词 .如： Theres a coat on the bed（对画线部分提问） 在床上有一件衣服。 How many coats are there on the bed? 在床上有多少件衣服？ Therere some meat in the bowl?（对画线部分提） 在碗里有一些肉。 How much meet is there in the bowl. ?在碗里有多少肉? 3. there be句型（三）there be与have(has)的用法区别：there be句型表示“某处

6、某时有某物或某人”，强调的是一种客观存在，但have表示“某人或某物有”，强调的是拥有或占有，即某物或某人与主语是所属关系，但有时它们也可以相互转换。I have a new bike我有一辆新自行车：The cat has two black ears。这只猫有两只黑耳朵。There are some flowers in the garden. 花园里面有很多花。There is a computer in Kangkangs room.= Kangkang has a computer in his room.在康康房间里有一台电脑。 二，时态1.现在进行时现在进行时表示正在发生或进行的

7、动作 ，常与now, at the moment，look，listen等词语或者短语连用。结构：主语+be(is,am,are)+现在分词。如：Mary is having lunch with her parents now 玛丽正和她的父母一起吃午餐。They are doing their homework at home. 他们正在家里做家庭作业。动词的现在分词的构成规则： 一般在词尾加-ing。 如：drink-drinking以不发音字母e结尾的动词，先去e，再加ing。如： make-making close-closing have-having以重读闭音节结尾的动词，且词尾

8、只有一个辅音字母，应先双写这个辅音字母，再加ing。如：Sit-sitting begin-beginning shop-shopping 2.一般过去时(1)一般过去时表示在过去某个时间发生的动作或存在的状态常和yesterday, last night/year, two days/weeks ago, just now. a moment ago，in 1990/2006等表示过去的时间状语连用。如： I was a student two years ago两年前我是一个学生。 He sang an English song yesterday昨天他唱了一首英文歌. Did he pe

9、rform Chinese kung fu at the party? 他在晚会上表演了中国功夫吗？ He was ill yesterday. So he didnt come to school. 昨天他生病了，所以他没来上学。(2)动词过去式的构成如下： 一般在动词原形末尾加-ed。如： look-looked, play-played 以不发音的e结尾的动词在末尾加-d。如： live-lived 末尾只有一个辅音字母的重读闭音节动词，双写这个辅音字母，再加-ed。如： plan-planned, stop-stopped 末尾是辅音字母加字母“y”的动词，先变v为i，再加-ed。如：

12、oulddo?will意愿，决心请求，建议，用在问句中would比较委婉will not/wont doWilldo?Yes,will. No, wont.wouldwouldnot/wouldnt do II. 情态动词must, may, might, could, can表示推测：以must为例。must + do(be)是推测现在存在的一般状态进行；must + be doing 推测可能正在进行的事情；must +have done是推测可能已经发生过的事情。1. must“肯定，一定”语气强，只用于肯定句中。He must be a man from America. / He m

13、ust be talking with his friend. / He must have already arrived there.2. may和might“也许”，后者语气弱，更没有把握。可用于肯定句和否定句。He may not be at home. / They might have finished their task. 3. can和could“可能”，could表示可疑的可能性，不及cant语气强，用于肯定、否定、疑问句中。The weather in that city could be cold now.We could have walked there; it w

14、as so near.（推测某事本来可能发生，但实际上没有发生）Can he be in the office now? No, he cant be there, for I saw him in the library just now.(语气很强，常用于疑问句和否定句中)III. 情态动词注意点：1. can和be able to: 都可以表示能力。但be able to可以表达“某事终于成功”，而can无法表达此意。Be able to有更多的时态。另外，两者不能重叠使用。 情态动词练习1. _ I take it out?
