*的過去進行時
when和while的區別 ①when是at or during the time that, 既指時間點,也可指一段時間; while是during the time that,只指一段時間,因此when引導的時間狀語從句中的動詞可以是終止性動詞,也可以是延續性動詞,而while從句中的動詞必須是延續性動詞。
②when 說明從句的動作和主句的動作可以是同時,也可以是先后發生;while 則強調主句的動作在從句動作的發生的過程中或主從句兩個動作同時發生。 ③由when引導的時間狀語從句,主句用過去進行時,從句應用一般過去時;如果從句和主句的動作同時發生,兩句都用過去進行時的時候,多用while引導,如: a. When the teacher came in, we were talking. 當此句改變主從句的位置時,則為: While we were talking, the teacher came in. b. They were singing while we were dancing. ④when和while 還可作并列連詞。
when表示“在那時”;while表示“而,卻”,表對照關系。如: a. The children were running to move the bag of rice when they heard the sound of a motor bike. 孩子們正要跑過去搬開那袋米,這時他們聽到了摩托車的聲音。
b. He is strong while his brother is weak. 他長得很結實,而他弟弟卻很瘦弱。 具體你可以參考這一段。
when,while,as引導時間狀語從句的區別 when,while,as顯然都可以引導時間狀語從句,但用法區別非常大。 一、when可以和延續性動詞連用,也可以和短暫性動詞連用;而while和as只能和延續性動詞連用。
① Why do you want a new job when youve got such a good one already?(get為短暫性動詞)你已經找到如此好的工作,為何還想再找新的? ②Sorry,I was out when you called me.(call為短暫性動詞)對不起,你打電話時我剛好外出了。 ③Strike while the iron is hot.(is為延續性動詞,表示一種持續的狀態)趁熱打鐵。
④ The students took notes as they listened.(listen為延續性動詞)學生們邊聽課邊做筆記。 二、when從句的謂語動詞可以在主句謂語動作之前、之后或同時發生;while和as從句的謂語動作必須是和主句謂語動作同時發生。
1.從句動作在主句動作前發生,只用 when。 ①When he had finished his homework,he took a short rest.(finished先發生)當他完成作業后,他休息了一會兒。
②When I got to the airport,the guests had left.(got to后發生)當我趕到飛機場時,客人們已經離開了。 2.從句動作和主句動作同時發生,且從句動作為延續性動詞時,when,while,as都可使用。
①When /While /As we were dancing,a stranger came in.(dance為延續性動詞)當我們跳舞時,一位陌生人走了進來。 ②When /While /As she was making a phonecall,I was writing a letter.(make為延續性動詞)當她在打電話時,我正在寫信。
3.當主句、從句動作同時進行,從句動作的時間概念淡化,而主要表示主句動作發生的背景或條件時,只能用 as。這時,as常表示“隨著……”;“一邊……,一邊……”之意。
① As the time went on,the weather got worse.(as表示“隨著……”之意) ② The atmosphere gets thinner and thinner as the height increases.隨著高度的增加,大氣越來越稀薄。 ③As years go by,China is getting stronger and richer.隨著時間一年一年過去,中國變得越來越富強了。
④The little girls sang as they went.小姑娘們一邊走,一邊唱。 ⑤The sad mother sat on the roadside,shouting as she was crying.傷心的媽媽坐在路邊,邊哭邊叫。
4.在將來時從句中,常用when,且從句須用一般時代替將來時。 ①You shall borrow the book when I have finished reading it.在我讀完這本書后,你可以借閱。
②When the manager comes here for a visit next week,Ill talk with him about this.下周,經理來這參觀時,我會和他談談此事。 三、when用于表示“一……就……”的句型中(指過去的事情)。
* hardly(=scarcely) done *。=Hardly / Scarcely had * *。
①I had hardly /scarcely closed my eyes when someone knocked at the door.=Hardly / Scarcely had I closed my eyes when someone knocked at the door.我剛一閉上眼,就有人在敲門了。 ②I had hardly /scarcely entered my room when the telephone rang.=Hardly /Scarcely had I entered my room when the telephone rang.我剛一走進房門,電話就響了 是,比如這個字典里的例子 While Mary was writing a letter, the children were playing outside. 瑪麗寫信時孩子都在外面玩兒 祝你考得好。

擴展資料:
cut既可用作及物動詞,也可用作不及e68a847a686964616f31333431336232物動詞。用作及物動詞時,可接簡單賓語,也可接雙賓語,其間接賓語可以轉化為介詞for的賓語,還可接由形容詞充當補足語的復合賓語;。
cut用作不及物動詞時,主語通常為無生命的東西,其主動形式常含有被動意義。注意接復合賓語時,如果賓語較長或包含有疑問詞或關系代〔副〕詞時,常置于用作補足語的形容詞之后。

4.英語句子語法分析
這道題大部分人的分析與你的都是錯的,不是雙動詞,也不過去公詞。
這里考的語法是動詞的一種:不完全不及物動詞,keep就是,這樣的動詞后可以接賓語,但即使接了賓語句子意思仍不完整,要接賓語補足語來使整個句子的意思完整。
我先舉個簡單的例子:
please keep the classroom clean.
翻譯:請保持教室清潔。keep接了賓語,保證教室,很明顯意思不完整,就接了形容詞clean使句子意思完整。下面我們回到這個句子:
1.首先看到is kept就知道中被動語態。我還原一下這個句子,加個主語你就看明白這種動詞的用法了。加主語HE
he keep neatly the lawn cut
he keep 副詞 the room clean
對應一下,看明白了嗎?
cut 就是形容詞做補足語,而原句多了個副詞是修飾動詞keep的。
把它變成被動你應該會吧
The lawn is kept neatly cut.
ok 哈哈哈
要做好這方面的句子分析,我建議你好好學一下動詞的五種形式:
1.完全及物動詞
2.不完全及物動詞
3.完全不及物動詞
4.不完全不及物動詞
5.授予動詞
你懂了這五種動詞之后就會發現這樣的句子太簡單了。
加分,我要加分,哈哈!!
5.是cut up the meat 還是cut the meat up
都可以的哦~cut up something 和 cut something up 沒有區別,兩者都可以.類似的動詞詞組還有:mix (sth) up;put (sth) off等等,結構是 動詞+副詞。
這一種動詞詞組,如果賓語是名詞,名詞放在中間或者放在后面都可以。如果賓語是代詞,就必須夾在中間.例如只能說:cut it up,mix them up,put it off,turn me down,switch it on不能說:*cut up it,*mix up them,*put off it,*turn down me,*switch on it 放后面,不能放中間。
