專題連詞辨析

1、課程信A年級初三1學科英語1版本1上海牛津版內(nèi)容標題寒假專題（二）編稿老師鄭月【本講教育信息】二教學內(nèi)容：寒假專題（二）學習過程一、連詞辨析連詞是用來連接詞、短語、句子或從句的詞。連詞屬于虛詞_，在句子中不重讀，不能單獨作句子成分。根據(jù)連詞的作用，可分為并列連詞，從屬連詞和短語連詞。（一）并列連詞-并列連詞是用來連接同等的詞、詞組或分句，常用的有also., either.or., neither.nor.等。and, but, or, so, for, not onl y.but（二）從屬連詞：從屬連詞用來引導名詞性從句和狀語從句。if, after, whe n, before, sinc

2、e, un til, because, although （though）常用的從屬連詞有that, whether,等。（三）短語連詞：短語連詞是由幾個詞組成的短語，起連接作用，常用的短語連詞有as soonas, in order that, as long as等。（四）連詞在使用時的幾點注意：-1、當either.or.?:, neither.nor., not only.but also .連接兩個主語時，其謂語動詞要與靠 近的主語一致。例如：Neither she nor I am a worker.2、 漢語的“雖然”但是” ”應是 能用其一；同樣漢語的“因為”所以，” 例如：因

3、為她有點餓，所以她開始做飯。although(though)或but,although(though)與but只 應譯成because或者so,不能說成because.so.。Because she was a little hun gry, she cooked some food.或She was a little hungry, so she cooked some food.3、for意為“因為”，是并列連詞，一般不能放在句首。例如：Youd better put on your overcoat, for its rather cold outside.4、and和or用在祈使句中，

4、and =if you.,youll.; or=if you don,youf.ll.。.例如：Work hard and youll pass the exam. = If you work hard, you will pass the exam.Get up early, or youll be late for school. = If you dont get up early, youll be late（五）兩組易混連詞的區(qū)別：1、whether和if引導名詞性從句，意為是否”時，whether引導的從句可以移到句首,if不可。例如：I cant say whether this

5、 is true or not.可說成：Whether this is true or no t, I cant saywww.chinaedu.cwww.chinaedu.c mmmm第1頁 版權所有 不得復制第3頁版權所有不得復制不可說：If this is true or not, I can .t saywhether可以引導表語從句和主語從句，表示“是否” ，if不能。例如：Whether it is true or not remains a question.它是不是真的還是一個問題。The question is whether he should do it.問題在于他是否應

6、該做這事。2、because, since和as表示原因是有一定區(qū)別的。because語氣最強。它是著重說明原因 或理由的從句，常位于主句之后。since的語氣比because稍弱，表示關系上的自然結果， 因此常譯成“既然；鑒于” 。as語氣最弱，只說明一般的因果關系。在回答以why提問的問句時，必須用because不用since或aso例如：-Why did he do that?-Because he thought that it was right to do that.Since you dont want to go to see the film, I won你既然不想去看電影，

7、我也不去了。二、most與most of的區(qū)別-（一）most后可直接跟名詞（可數(shù)或不可數(shù)I ），同時，也可接有形容詞修飾的名詞。 注意：跟可數(shù)名詞時，謂語動詞要用復數(shù)形式。如：Most boys like playing football.大部分男孩都喜歡踢足球。I always spend most time learni ng En glish.我總是花大部分時間在學習英語上。（二）既然most后不能直接跟有定冠詞、指示代詞或物主代詞所修飾的名詞，那么，該怎 么辦呢？答案是：遇到這些情況用-most of代替most。如：I spent most of my time lear ning

8、 to p lay the piano last year.去年我把大部分時間都花在學彈鋼琴上了。L II did most of that difficult work.那件困難的工作絕大部分都是由我做的。most of后跟人稱代詞時，應用復數(shù)形式的人稱代詞賓格。如：Most of them are going off to Guangzhou next week.他們中的多數(shù)人都準備下星期去廣 州。most前有定冠詞時，可用來修飾多音節(jié)形容詞，表示最高級，意為“最”This is the most beautiful flower.這是最漂亮的花。如果most前有不定冠詞a,則表示“非常；

9、很”，相當于very。如：She is a most beautiful girl.她是個非常漂亮的姑娘。most of后接表示時間的名詞時，在句中可作狀語，修飾謂語動詞。如：Most of the time we eat fish.絕大部分時間我們都吃魚肉。三、seem的用法丨seem為連系動詞，意為“似乎；好像；看起來”，（一）seem（to be）+名詞。例如：Mary seems a very clever girl.瑪麗看上去是一個非常聰明的女孩。The young man seems to be a new teacher.這個年輕人看上去像一位新老師。（二）seem（to be）

10、+形容詞或過去分詞。例如：Mr Smith seemed to be quite happy.史密斯先生好像十分快樂。This small town seems changed a little.這個小城鎮(zhèn)似乎有點兒變化。t go, either.。如:www.chinaedu.cwww.chinaedu.c口m m第4頁版權所有不得復制www.chinaedu.cwww.chinaedu.c mmmm（三）seem+不定式。不定式有時須用進行時或完成時。例如:Mrs Black doesnt semeems not） to like the idea.布萊克夫人似乎不太喜歡這個主意。The

11、childre n seemed to be eati ng somethi ng in the room.孩子們好像正在房間里吃東西。The young girl seemed to have changed much.這個年輕女孩看來變化很大。（四）seem+介詞短語。例如:It seems like years since I last saw you.從上次跟你見面后，好像有好多年沒有見到你了。They seem like many stars.它們好像許多星星。Her parents seem in good health.她的父母看起來很健康。（五）It seems that.意為

12、“看起來；似乎”。例如：It seems that no one knows what has happened in the p ark.也可說No one seems to know what has happened in the park.似乎沒有人知道在公園里發(fā)生了什么事。It seems to me that Mr. White will n ot come agai n.依我看，懷特先生不會再來了。（六）There seems（to be）.意為“似乎有”。例如：I IThere seems（to be） no need to wait.看來無須再等了。（七）It seems a

13、s if.意為“看起來像（仿佛）,，”。從句常用虛擬語氣。例如：It seems as if they had n ever see n each other before.仿佛他們以前從未見過面。seem和look均可表示“看起來；好像”，但意思略有差別：seem指說話人的主觀判 斷；look則指從外表上看給說話人的印象。例如：Jack seems like his father.杰克似乎像他父親。（說話人的一種主觀判斷）Jack looks like his father.杰克看起來像他父親。（指杰克的長相讓人看起來像）四、不加not變否定句（一）改變副詞。例如： _1. He is al

14、ways late for school. He is neverlate for school.2.The boy almost always goes to bed at 10:00.3.He is still a worker. He is no-ton ger a worker.（二）改變連詞。例如：Both Jim and Tom like read ing.NeitherJim nor Tom likes readi ng.（三）改變不定代詞。例如:1. All of the stude nts are from the coun tryside.None of the stuet

15、e nts are from the coun tryside.2.He knows someth ing about your school. He knows nothing about your school.本句也可改為He doesnt know anythingabout your school.7 The boy hardltyaeVat goes） towww.chinaedu.cwww.chinaedu.c口m m第5頁版權所有不得復制3.I know both of them.
