九年級英語知識點:重點副詞
1. later、after、ago、before的用法:①“一段時間+later/ago”分別表示“(多久)以后/以前”,主要用于過去時態(tài)。②“after/before+某個時刻”分別表示“在某時刻之后/之前”,此時兩個詞是介詞。③ago與before:ago只能用于過去時,before用于完成時。如:He had an accident a week ago.(一周前出了一個事故)/ Some years later, the boy became a very famous singer.(數(shù)年后這個男孩成了著名的歌唱家)/ Have you been there before?(你從前到過那兒嗎?)/ After a few years he gave up smoking.(過了幾年他戒了煙。)
2.above、below、over、under的用法:在上下方用above和below,在高低處用over和under。如:The stars are high above in the sky.(星星高掛在空中) / A plane flew over quickly.(一架飛機從頭頂飛過。)
當above、below、over、under是介詞性質(zhì)時,意義相似。
3.as…as…常構(gòu)成一些詞組:as soon as…(一旦…就…), as well as…(同樣),as+形容詞/副詞+as possible(盡可能……地)。如:Please ring me up as soon as you get to Beijing.(請你一到北京就給我寫信。)/ Miss Gao hurried to the school gate as quickly as possible.(高小姐盡快地趕到了校門口。)
[注釋] “as long / much as + 名詞”可以表示“長達/多達…”的含義。如:The house costs as much as five hundred thousand yuan.(那幢房子花費高達50萬元。)/ They stayed in the cave(山洞)as long as two weeks.(他們呆在山洞里長達兩周。)
4.too、also、either、nor的用法:too(“也”)用于肯定句和疑問句的末尾,且用逗號隔開;also(“也”)用于肯定句句子謂語動詞之前;either(“也”)用于否定句末尾,也用逗號隔開;nor(“也不”)用于倒裝句句首;如:Are you American,too?(你也是美國人嗎?)/ 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.(他沒有看足球賽,我也沒有。)/ You can also find the market is very good.(你還可以發(fā)覺那個市場很好。)
5. enough、too、so、very、quite、very much的用法: enough (“足夠,十分”)放在形容詞或副詞之后;too(“太”)、very(“非常”)、quite(“相當”)、so(“如此地”)等放在形容詞或副詞之前,very much(“非常”)放在動詞之后。如:It's too/so/very/quite expensive.(它太貴/那么貴/非常貴/相當貴。)/ I don't like sweets very much.(我不很喜歡糖果)
[注意] very與 much的區(qū)別:very修飾形容詞、副詞的原級和現(xiàn)在分詞形容詞,much修飾形容詞和副詞的比較級;much還可以修飾疑問句和否定句中的動詞,very不可以。如:He is very stupid.(他很笨)/ The film was very moving and everyone swept.(電影非常動人,大家都哭了)/ You must work much harder or you will fail to enter the good school.(你得學習更努力,不然你考不進那所好學校)/ I don't like him much.(我不太喜歡他)
6. sometimes、sometime、some times 、some time的用法:sometimes(有時)用于一般現(xiàn)在時、sometime(在將來某時)用于將來時、some times(數(shù)次)表示次數(shù)、some time(一些時間)表示一段時間。如:Sometimes they go hiking in the mountains.(他們有時徒步旅行到山里去)/ I will stay here some time.(我會在這兒呆些時候的。)/ I will meet your father sometime.(我什么時候要見見你的父親。)
7. how、what用于感嘆句的用法:對句子中的形容詞或副詞感嘆時用how,對人或事物(可能含有形容詞作修飾語)進行感嘆用what. 如:What a fine day (it is) today!(今天天氣真好!) / How difficult (the problem is)!((問題)真難呀!)

9. hard與hardly的用法:hard作為副詞意思是:“努力地,猛烈地”,hardly是否定詞,意思是:“幾乎不”,一般與情態(tài)動詞can/could連用。如:They study English very hard.(他們英語學得很刻苦)/ You can hardly see a person spit in a public place.(在公共場所你幾乎看不到一個人隨地吐痰)
10. like…very much、like…better(=prefer)、like…best的用法:三個短語分別表示“非常喜歡”、“更喜歡”、“最喜歡”。如:I like baseball very much.(我非常喜歡棒球)/ Do you like butter better than cheese?( / They like hamburgers best.
11.“quite/what+a+形容詞+名詞”的用法:記?。孩賟uite/such/what…+a+形容詞+名詞;②too/so/how+形容詞+a+名詞;③rather+a+形容詞+名詞 = a+ rather+形容詞+名詞。如:I have never seen such a strange guy(家伙)。(我從未見過這樣奇怪的家伙) / It is quite a nice day for a walk.(這真是散步的好日子)

九年級英語知識點:動詞語態(tài)
和時態(tài)一樣,語態(tài)也是動詞的一種形式,用來說明句中主語和謂語的關系。如果動作由主語執(zhí)行,就可使用主動語態(tài),如果主語不是由主語執(zhí)行,主語是動作的承受者,則可使用被動語態(tài)。由此我們可以看出英語動詞有兩種語態(tài):主動語態(tài)和被動語態(tài)。
被動語態(tài):表示主語是動作的承受者,什么事情被主語做。被動語態(tài)的構(gòu)成和形式被動語態(tài)由“助動詞be+及物動詞的過去分詞”構(gòu)成,一定要記住是及物動詞。助動詞必須與主語的人稱和數(shù)一致,注意要與我們前一講學過的八個時態(tài)配合使用。
適合被動語態(tài)的情況:
不知道動作由誰發(fā)出,或由于某種原因沒有必要說明誰發(fā)出動作。如:This table is made of wood. 需要突出或強調(diào)動作的承受者時,如:This park was built for children.
注意:主動句中的主語如果是people,they,somebody等含糊的表示“人或人們”,沒有確指執(zhí)行者是誰,為被動句時,通常省略“by+執(zhí)行者”。如:The door was opened secretly. But nobody came in.
注意:在主動句里,不定式在make,see,hear等動詞后面作賓語補足語時都不帶to,但變成被動句時,后面的不定式都需帶to。如:He was made to do that work.
主動語態(tài)不能變被動語態(tài)的情況:學了被動語態(tài),別以為主動句和被動句可以隨意轉(zhuǎn)換,千萬要注意呀!有些主動語態(tài)不能轉(zhuǎn)換成被動語態(tài)。當賓語是反身代詞時,如:You should take care of yourself.當謂語是表狀態(tài)的而不是表具體動作的及物動詞時,如:Does the skirt suit you?
