九年级英语知识点:重点副词

1. later、after、ago、before的用法:①“一段时间+later/ago”分别表示“(多久)以后/以前”,主要用于过去时态。②“after/before+某个时刻”分别表示“在某时刻之后/之前”,此时两个词是介词。③ago与before:ago只能用于过去时,before用于完成时。如:He had an accident a week ago.(一周前出了一个事故)/ Some years later, the boy became a very famous singer.(数年后这个男孩成了著名的歌唱家)/ Have you been there before?(你从前到过那儿吗?)/ After a few years he gave up smoking.(过了几年他戒了烟。)

2.above、below、over、under的用法:在上下方用above和below,在高低处用over和under。如:The stars are high above in the sky.(星星高挂在空中) / A plane flew over quickly.(一架飞机从头顶飞过。)

当above、below、over、under是介词性质时,意义相似。

3.as…as…常构成一些词组:as soon as…(一旦…就…), as well as…(同样),as+形容词/副词+as possible(尽可能……地)。如:Please ring me up as soon as you get to Beijing.(请你一到北京就给我写信。)/ Miss Gao hurried to the school gate as quickly as possible.(高小姐尽快地赶到了校门口。)

[注释] “as long / much as + 名词”可以表示“长达/多达…”的含义。如:The house costs as much as five hundred thousand yuan.(那幢房子花费高达50万元。)/ They stayed in the cave(山洞)as long as two weeks.(他们呆在山洞里长达两周。)

4.too、also、either、nor的用法:too(“也”)用于肯定句和疑问句的末尾,且用逗号隔开;also(“也”)用于肯定句句子谓语动词之前;either(“也”)用于否定句末尾,也用逗号隔开;nor(“也不”)用于倒装句句首;如:Are you American,too?(你也是美国人吗?)/ He is not happy and I am not happy, either.(他不愉快,我也不。) / He didn't watch the football game. Nor did I.(他没有看足球赛,我也没有。)/ You can also find the market is very good.(你还可以发觉那个市场很好。)

[注意] very与 much的区别:very修饰形容词、副词的原级和现在分词形容词,much修饰形容词和副词的比较级;much还可以修饰疑问句和否定句中的动词,very不可以。如:He is very stupid.(他很笨)/ The film was very moving and everyone swept.(电影非常动人,大家都哭了)/ You must work much harder or you will fail to enter the good school.(你得学习更努力,不然你考不进那所好学校)/ I don't like him much.(我不太喜欢他)

8.already、yet的用法:在完成时中,already一般用于肯定句,yet一般用于否定句和疑问句。如:Have you done it already?(你已经做好了?) / I have not had my breakfast yet.(我还没有吃早饭呢。)

9. hard与hardly的用法:hard作为副词意思是:“努力地,猛烈地”,hardly是否定词,意思是:“几乎不”,一般与情态动词can/could连用。如:They study English very hard.(他们英语学得很刻苦)/ You can hardly see a person spit in a public place.(在公共场所你几乎看不到一个人随地吐痰)

10. like…very much、like…better(=prefer)、like…best的用法:三个短语分别表示“非常喜欢”、“更喜欢”、“最喜欢”。如:I like baseball very much.(我非常喜欢棒球)/ Do you like butter better than cheese?( / They like hamburgers best.

11.“quite/what+a+形容词+名词”的用法:记住:①quite/such/what…+a+形容词+名词;②too/so/how+形容词+a+名词;③rather+a+形容词+名词 = a+ rather+形容词+名词。如:I have never seen such a strange guy(家伙)。(我从未见过这样奇怪的家伙) / It is quite a nice day for a walk.(这真是散步的好日子)

九年级英语知识点:动词语态

和时态一样,语态也是动词的一种形式,用来说明句中主语和谓语的关系。如果动作由主语执行,就可使用主动语态,如果主语不是由主语执行,主语是动作的承受者,则可使用被动语态。由此我们可以看出英语动词有两种语态:主动语态和被动语态。

被动语态:表示主语是动作的承受者,什么事情被主语做。被动语态的构成和形式被动语态由“助动词be+及物动词的过去分词”构成,一定要记住是及物动词。助动词必须与主语的人称和数一致,注意要与我们前一讲学过的八个时态配合使用。

适合被动语态的情况:

不知道动作由谁发出,或由于某种原因没有必要说明谁发出动作。如:This table is made of wood. 需要突出或强调动作的承受者时,如:This park was built for children.

注意:主动句中的主语如果是people,they,somebody等含糊的表示“人或人们”,没有确指执行者是谁,为被动句时,通常省略“by+执行者”。如:The door was opened secretly. But nobody came in.

注意:在主动句里,不定式在make,see,hear等动词后面作宾语补足语时都不带to,但变成被动句时,后面的不定式都需带to。如:He was made to do that work.

主动语态不能变被动语态的情况:学了被动语态,别以为主动句和被动句可以随意转换,千万要注意呀!有些主动语态不能转换成被动语态。当宾语是反身代词时,如:You should take care of yourself.当谓语是表状态的而不是表具体动作的及物动词时,如:Does the skirt suit you?
