九年级上Unit3语言点归纳

1、九年级上Unit3语言点归纳1.语态：英语有两种语态：主动语态和补动语态主动语态表示主语是动作的执行者被动语态表示主语是动作的承受者Cats eat fish. （主动语态）猫吃鱼。 Fish  is eaten  by cats.(被动语态)鱼被猫吃。 被动语态的构成由“助动词be 及物动词的过去分词”构成助动词be 有人称、数和时态的变化，其变化规则与be 作为连系动词时完全一样。时态被动语态结构例句一般现在  时am are +过去分词is English is spoken in many countries.一般过去  时was +过去分词we

2、re + 过去分词This bridge was built in 1989.情 态动 词can/shouldmay  +be+过去分词must/The work must be done right now.   被动语态的用法当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者，或者只需强调动作的承受者时，要用被动语态。2. allow sb. to do sth. 允许某人做某事（主动语态）如：Mother allows me to watch TV every night. 妈妈允许我每晚看电视。be allowed to do sth. 被允许

3、做某事（被动语态）如：LiLy is allowed to go to Qinzhou. 莉莉被允许去钦州。3. get their ears pierced 穿耳洞让/使（别人）做某事 get sth. done(过去分词)  have sth. done        如：I get my car made. = I have my car made. 我让别人修好我的车4. enough 足够形容词enough  如：beautiful enough足够漂亮  enough名词如：enou

6、表语一起构成谓语。常用的连系动词有：look, feel, be, become, get, turn, smell, taste, stay(保持), kept等。连系动词除be 和become 等少数词可接名词作表语外，一般都是接形容词。如：They are very happy.    He became a doctor two years ago. She felt very tired.8. 倒装句: 由so助动词(be/do/will/have)/情态动词主语意为：也是一样She is a student. So am I.她是一个学生，我也是。&#

7、160;She went to school just now. So did I . 她刚才去学校了，我也是 She has finished the work. So have I . 她已经完成了工作,我也完成了。 She will go to school. So will he.她将去学校，他也是。9. yet 仍然，还常用在否定句或疑问句当中10. stay up 熬夜如：I often stay up until 12:00pm.我经常熬夜到12点。11. clean up 打扫整理如：I have cleaned up the bedroom. 我已经打扫完

10、leaned every day .     The office was cleaned yesterday.     Compare active（主动） and passive（被动）：    动作的接受者the office成了句子的主语，就应该用被动语态。从上面的例句我们可以总结：    一般现在时的被动语态为：主am / is / are （not）过去分词    一般过去时的被动语态为：主was / were 过去分词 &

11、#160;  如：Butter is made from milk.     This house was built 100 years ago.     以前我们学过的was / were born 生于，就是一个被动语态    born是个过去分词（bear）    When were you born ? I was born in 1989.     如果要特别强调动作或行为的执行者，句子后面需接by ，译为“被（由）”

12、60;   如：We were woken up by a loud noise .    我们被嘈杂的声音吵醒。    从上面例子，我们可以看出，现在进行时被动语态的构成为    主语is / am / are + being 过去分词    再如：    My car is being repaired now.     Some new houses are being built near

13、 the park.     公园附近在建一些房子。    从上面例子，我们可以看出现在完成时被动语态的构成为    主语have / has been 过去分词 如：    My key has been stolen.     My keys have been stolen.     I am not going to the party , I havent been invited.   

14、;  含有情态动词的被动语态    情态动词be过去分词    A note had better be left to him.     Teenagers should be allowed to wear their own clothes   各种时态的被动形式 (1) 一般现在时： am, is, are + 过去分词 (2) 一般过去时： was, were +过去分词 (3) 情态动词： can/could/may/must/should be + 过

15、去分词*(4) 一般将来时： will be/be going to be + 过去分词*(5) 进行时： am, is, are, was, were being + 过去分词 *(6) 完成时： have/has been + 过去分词    被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be动词后面的过去分词不变。归纳：    肯定句：主语be + 过去分词（by ）    否定句：主语be not 过去分词（by ）    一般疑问句：Be 主

16、语过去分词（by ）?     特殊疑问句：疑问词be主语过去分词（by ）  3. 被动语态的用法：    （1）不知道或没有必要说明动作的执行者是谁，不用by动作执行者短语    Such books are written for children.     这些书是为儿童写的。    I havent been told about it .     没有人告诉我这件事  

17、60; （2）强调动作的承受者，这时应用by短语。    The cup was broken by David.     （3）作客观说明时，常采用一种被动语态句型    Its / was said / believed / reported / + that     Its reported that about three hundred people were killed in this earthquake.     据报道，这次地

18、震中大约有三百人死亡。  4. 主动语态变为被动语态    把主动语态的句子变为被动语态的方法是：    （1）把原句中的宾语变为主语    （2）动词改为被动形式，即be+过去分词    （3）原来的主语，如果需要的话，放在by后面，如果没必要，可省略。    注意事项：    主动语态变成被动语态应注意事项    从主动语态到被动语态的过程中主语、谓语动词、宾语都发生变化。

19、    注意主格与宾格的变化形式。    注意主语的人称及数的变化对be动词带来的影响。注意be动词的时态形式取决于原主动语态的动词时态形式。一、用read的被动语态填空。1. A book _ by Tom every week 2 . A book _ by Tom last week.3. A book _ by Tom next week.4. A book _ by Tom for a week.5. A book _ by Tom while we were visiting him.6. A book might _ b
