7年级下册英语重点知识点1

  1.have“有”啥用法。

  have是英语中很有用的动词,基本含义是“有”。如课文中的“Ihaveasoccerball.”have在he,she,it后面要变成has,即:一般现在时态第三人称单数形式。

  如:Hehasabasketball.

  have当动词“有”的意思时,句式是:

  陈述句:Ihaveanicebag.我有一个不错的包。

  疑问句:Doyouhaveanicebag?Yes,Ido.No,Idon't.

  你有一个漂亮的包吗?是的,我有。不,我没有。

  否定句:Idon'thaveanicebag.

  我没有漂亮的包

  have与其它的词组合成词组、短语,就不表示有了,其意思由后面的名词决定。如:

  haveclasses(上课);havebreakfast(吃早饭);haveagoodtime(玩得高兴);havesports(进行体育活动);haveadayoff(休假)等等。

  have与therebe句型的区别

  therebe是表示“在某处存在某物”,而have则是表示所属的意思,即“拥有”,通常主语是人。我们来看两个句子:

  Thereisabookonthedesk.书桌上有一本书。

  Ihavemanybooks.我有很多本书。

  2.Let's的用法。

  句中的let's表示“让我们”,这个句型表示说话人的建议,建议说话人和听话人一起去做某事情,它是letus的缩写形式,但用letus表示的是说话人建议听话人让说话人干某事。如:

  Let'sgotoschool.让我们到学校去。

  Let'splaybasketball.让我们打篮球去。

  MrWang,letusreadthebooknow.

  王老师,让我们读课文吧。

  一.动词be(is,am,are)的用法

  我(I)用am, 你(you)用are,is跟着他(he),她(she),它(it)。单数名词用is,复数名词全用are。变否定,更容易,be后not加上去。变疑问,往前提,句末问号莫丢弃。还有一条须注意,句首大写莫忘记。

  二.this,that和it用法

  (1)this和that是指示代词,it是人称代词。

  (2)距离说话人近的人或物用this, 距离说话人远的人或物用that。如:

  This is a flower. 这是一朵花。(近处)

  That is a tree. 那是一棵树。(远处)

  (3)放在一起的两样东西,先说this, 后说that。如:

  This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。

  (4)向别人介绍某人时说This is…, 不说That is…。如:

  This is Helen. Helen, this is Tom. 这是海伦,海伦,这是汤姆。

  (5)This is 不能缩写, 而That is可以缩写。如:

  This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。

  (6)打电话时,介绍自己用this, 询问对方用that。如:

  —Hello! Is that Miss Green? 喂,是格林小姐吗?

  —Yes, this is. Who’s that? 是的,我是,你是谁?

  注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:I am…, Are you…?/Who are you?

  (7)在回答this或that作主语的疑问句时, 要用it代替this或that。如:

  ①—Is this a notebook? 这是笔记本吗?

  —Yes, it is. 是的,它是。

  ②—What’s that? 那是什么?

  —It’s a kite. 是只风筝。

  状语从句

  状语从句主要用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下:

  1.时间状语从句

  常用引导词:when, as, while, as soon as, before, after, since, till, until, whenever

  e.g.Don’t come in until you are called.

  While John was watching TV, his wife was cooking.

  I called my mother as soon as I reached Shanghai.

  I have been an English teacher since I came to the school.

  2.地点状语从句

  常用引导词:where, wherever

  e.g.Generally, air will be heavily polluted where there are factories.

  Wherever you go, you should work hard.

  3.原因状语从句

  常用引导词:because, since, as, for

  e.g.I didn’t go surfing because it was too cold.

  As the car was expensive, we didn’t buy it.

  Since he was busy, he didn’t come.

  4.目的状语从句

  常用引导词:so that, in order that

  e.g.You should talk to him so that/in order that you can say you are sorry.

  5.结果状语从句

  常用引导词:so…that, such…that

  e.g.He got up so early that he caught the first bus.

  It’s such a good chance that we must not miss it.

  6.条件状语从句

  常用引导词:if, unless, as long as

  e.g.We’ll start our project if the president agrees.

  You will certainly succeed so long as you keep on trying.

  注意:在时间状语从句和条件状语从句中通常用一般现在时表一般将来时间。

  e.g.—When will Lisa come back?

  —Sorry I don’t know. When she comes back, I will call you.

  If you go to the party, you’ll have a good time.

  Unless it rains tomorrow, we will go for a picnic.

  7.让步状语从句

  常用引导词:though, although, even if, even though

  e.g.Although the traffic was heavy, we got to the railway station on time.

  Even though he is 80, he still looks strong and healthy.
