第一篇:四年級英語帶be動詞
四年級英語帶be動詞(is are)的一般疑問句專項訓練 班級__________ 姓名_____________
1、陳述句和一般疑問句的簡單概念。
* 陳述句也叫肯定句。是描述一個事實,陳述一件事情。如:
This is a book.這是一本書。He is a student.他是一個學生。It is red.它是紅色的。They are on the desk.他們在桌上。There are 2 apples on the tree.樹上有2個蘋果。、? 一般疑問句也叫做YES or NO疑問句,是提出一個猜測,讓對方回答Yes或者No的問句。
Is this a book? 這是一本書嗎? Is he a student? 他是一個學生嗎? Is it red? 它是紅色的嗎?
Are they on the desk? 他們在桌上嗎? Are there 2 apples on the tree? 樹上有2個蘋果嗎?
2、如何講陳述句轉化為一般疑問句。
基本口訣: Be動詞(is are)提前,其余要照抄,大小寫調整,結尾改問號。如: 陳述句: She is in the study.她在書房里。They are red.他們是紅色的。疑問句: Is she in the study?她在書房里嗎? Are they red?他們是紅色的嗎?
3、一般疑問句回答的注意要點。
一般疑問句也叫做YES or NO疑問句,就是說回答必須是Yes或者No。比如說: 陳述句: She is in the study.她在書房里。疑問句: Is she in the study?她在書房里嗎?
回答1: Yes,she is in the study.是的,她在書房里。No, she is not in the study.回答

第二篇:英語動詞
第十二講 英語動詞 [1]
[新E英語 沈章柱
2007-10-18]
一、動詞的概念
顧名思義,動詞就是表示動作的詞。所謂動作,絕大多數是可以感知到的,比如汽車在開,人在看電視,太陽升起降落,等等。也有些動作不是直接能看到聽到的,例如思考問題,制定方案,經濟發展,等等。不管怎么說,這些動作都比較明顯,直接或間接地被我們覺察出來。但是,英語動詞還有一類是表示“狀態”的。這些動詞并沒有直觀的動作,它只是表示事物存在的一種狀態。例如:我是一個學生。其中的“是”,在英語中就是動詞;再例如:我們有一個籃球。其中的“有”也是動詞;等等。這類表示狀態的動詞,對于初學者來說要多加留意,它們也必須按照動詞的規律來使用。
二、動詞的分類
1、根據動詞的意義分類
(1)實義動詞和非實義動詞(助動詞)動詞屬于“實詞”的一種。所謂實詞,就是有明確具體的含義,像名詞的桌子、貓狗德行,形容詞的紅黃藍綠等等,動詞的哭笑、走路等等。而英語中其它的一些詞類如冠詞、介詞等等,意義比較地空虛,所以叫做虛詞。根據動詞是不是有明確具體的意思,動詞本身也分成所謂的實義動詞和非實義動詞。實義動詞就是動作比較明顯具體,像上面講到的汽車在開,人在看電視,太陽升起,思考問題,制定方案,經濟發展,等等。非實義動詞通稱為助動詞,如can, may, will, shall 等等。注意:有少數動詞既可以算作實義動詞,也是助動詞。也就是說,這些動詞既可以作實義動詞,在另外情況下它又是助動詞,如:be, have, look, seem 等。請看例句: 例1:I have my supper at about 6:30 every day.我每在6:30 左右吃晚飯。(這兒,have 是實義動詞。)例2:The students have planted many trees.學生們種了許多樹。(這兒,have planted 中的have 是完成時態的助動詞。)
(2)短時動詞和持續動詞
短時動詞也稱瞬時動詞,是說這些動作在很短時間內就完成了,它不太可能持續很長的時間,例如:leave(離開)borrow(借), buy(買),等等。相反,持續動詞表示的是,這些動作是一種持續性的動作,它可以連續不斷地發生,例如:write(寫), walk(走路), sleep(睡覺)等等。
一個動作是短時動詞還是持續動詞,也就是動作持續時間的長或短,在英語中對于正確使用動詞的時態非常有用。而有些動詞,短時與長時所用的動詞是不一樣的。這一點在中文里是沒有的,也是初學者經常遇到的問題之一。請看例句: 例1:當 Tom 到達的時候,他得知 Mary 已經離開將近三個小時了。
[錯] When Tom arrived he learned Mary had left for almost three hours.因為過去完成時 had left 和 for 連用,有不停地離開的意思,英語中算作錯誤。
[對] When Tom arrived he learned Mary had been away for almost three hours.要表示持續的狀態,可以改用系表結構 had been away。例2:她那天穿著一件新裙子。
[錯] She put on a new dress that day.put on 表示“穿上”的短時動作。顯然,她不可能一天總是在那兒穿來穿去。
[對] She wore a new dress that day.wear 表示“穿著”的狀態,是持續動詞。
例3:他丟了包有三天了。
[錯] He has lost his bag for three days.丟東西是很短時間發生的事,不可能連續三天才把包丟掉。for 表示持續的一段時間。
[對] He lost his bag three days ago./ It is three days since he lost his bag.1、及物動詞
及物動詞的意思是,謂語動詞后必須接一個賓語,表明謂語動詞所影響到的對像或者目標。這樣,句子的意思才比較完整。例如上例中,discuss 后接了一個 the usage of verb,指出了我們討論的對象(或目標),整句話連起來就是:weusage(我們討論用法),基本上表達出了句子的主要意思。再例如:The boy see a picture on the wall.如果只說 see,聽者可能就會問 see 了什么?這里候必須接一個具體的內容 a picture,這樣意思就比較完整了。
及物動詞在英語里用縮寫 v.t.表示。
2、不及物動詞
不及物動詞,意思就是它不需要后面接賓語,句子意思本身就清楚了。
例如:A car is running along the bridge.run 是謂語,說汽車在開。我們聽到了 carFreanch)我能看懂法文,但不會說。
We read about the storm in the paper today.(read 用作不及物:read-about)從今天的報紙上我們得知今天有風暴
(2)有的詞只用作不及物動詞,如果要接賓語,必須后接介詞。這些加了介詞的不及物動詞,很多有固定的意思,因而也被稱作“動詞短語”。例如:
He turned on the torch to look for his keys.他打開了手電筒,尋找鑰匙。(turn on 與 look for)The children always lag(緩緩而行)behind when we go for a walk.(go for)我們出去散步時,孩子們總是落在后面。
2、實義動詞(及物、不及物)與助動詞
及物與不及物動詞都是實義動詞,有著明確具體的含義。相對來說,助動詞的意義就比較虛了。助動詞的用法在講時態的時候還會專門講述。這里要說的是,英語有些動詞既可以做實義動詞,也可以用作助動詞。這一點請初學者要搞清楚。例如:
I am a student of Class Two.[ 這里am 是實義動詞] 我是一個二班的學生。
I am playing basketball.[這里am 是助動詞] 我在打籃球。
We have a clean and tidy classroom.[ have 是實義動詞] 我們有一間干凈整齊的教室。
We have learned 1000 words this term.[ have 是助動詞] 這學期我們學了1000個單詞。
3、謂語動詞的變化
英語中,謂語動詞的變化非常復雜。這是由英語表達的特點決定的。簡單地說,英語在表示一個動作的時態,特別注意兩個問題:一是動作發生的時間,是過去、現在還是將來等等;二是動作持續的狀態,是做完了、正在進行、一直持續等等。同一個動作,在不同的時間、不同的狀態的時候,要用動詞的不同形式來表達,這就是所謂動詞的過去式、一般現在時、正在進行時等等的原因。關于這方面的問題,這里只提示一下,以后講時態的時候將專門進行講解。例如:
He does his exercise every day.[ does 表示一般現在時,does 是單數第三人稱。] 他每天都做鍛煉。He is doing his exercise now.[ is doing 表示現在進行時, doing 叫現在分詞。] 他正在鍛煉。
He has done his exercise and for two months.[ has done 現在完成時,done 叫過去分詞。] 他鍛煉有兩個月了。
1、限定性動詞和非限定性的動詞
限定與非限定動詞,是從主語與謂語的搭配關系來說的。限定動詞是指動詞變與不變受主語的人稱(第一、第二、第三人稱)和是單數還是復數的限制。它主要出現在一般現在時及少數的時態中。
例如,在一般現在時中,I, you, we 和復數名詞形式時謂語動詞不需要進行變化;如果是單數第三人稱,動詞則要進行變化。(這種情況也叫“主語、謂語的一致”。)請看例句: We go to school on weekdays.我們天天上學。(we 是復數,go 不需要變化。)He goes to school on weekdays.他天天上學。(he 是第三人稱單數,go 需要變成 goes。)I shall play football on Saturday.我星期六將踢足球。(I 后要用 shall 表示將來。)The boys will play football on Saturday.男生們星期六將踢足球。(boys 是第三人稱,要用 will 表示將來。)與此相反,有些動詞則不受主語的人稱和單數、復數的影響,此是就叫非限定動詞。非限定動詞主要出現在各類非謂語動詞中,因為它們都是非謂語動詞,所以一般不受主語的限制。
2、規則動詞和不規則動詞
上面說了,動詞有各種變化形式。英語動詞的變化,有些是有規則的,就叫規則動詞;如果沒有規律,就叫不規則動詞。規則與不規則動詞主要出現在動詞的時態中。
例如,在一般現在時中,I, you, we 和復數名詞形式時謂語動詞不需要進行變化;如果是單數第三人稱,動詞的變化則有以下的規則:
一般情況下,直接在動詞后加 s,此時就叫“規則動詞”。例如:
He likes watching TV.他喜歡看電視。(like 變成了 likes)It looks like a cat.它看起來像只貓。(look變成了looks)其它如:help(幫助)-helps ;come(來)teaches ;wash(洗)goes;kiss(吻)-kisses ;fix(安裝)-fixes 但是有少數動詞,它們的變化是沒有規律的,此時就稱它們為“ 不規則動詞”,例如:
have(有)am / is / are 等。
在動詞的過去式、過去分詞的變化中,同樣存在著規則變化與不規則變化。
例如:過去式 規則變化:
work(原形)worked(過去分詞);play(原形)played(過去分詞)不規則變化:
sing(原形)sang(過去式)sung(過去分詞);grow(原形)grew(過去式)grown(過去分詞)
3、系動詞、情態動詞、感官動詞等
系動詞:它們一般是表示事物某種狀態(或緩慢變化)的動詞,如:be, keep, get, remain 等等。
情態動詞:是表示“能、可以、必須”等的詞,如:can, may, must 等。感官動詞:專門表示人的感官動作的動詞,如:feel, smell, sound, taste 等等
