我用牛津大辭典裏麵最標準的知識回答你,因為需要的就是標準的書麵符號。while表示轉折的時候,和漢語中的“然而”是一個意思,是在一個句子內的,作為連詞。used to show a contrast,例句I like drinking black coffee while she prefers it with cream,中間是不需要符號的。在做“雖然”這個意思用這個詞的時候,一般放在句首(讓步狀語從句),句中用逗號。
while表轉折句後是不是不能加but
不用加but。
如果while表轉折的話,同一個句子中不能出現兩個意思相近的連詞(比如說though,but不能同在一個句中)。
While作並列連詞用,意思為“而,然而”,表對比。
而but表轉折。
例句:1.Some people waste food while others haven't enough. 有些人很費糧食,然而有些人卻吃不飽。
2.The son was having a good meal at home,while the parents were working in the fields. 兒子在家吃好飯而父母卻在田裏辛勤勞作。
3.I ought to have helped her,but I never could.我本該幫她但沒能。
4.Honey is sweet,but the bee stings. 蜂蜜很甜,但蜜蜂有刺蜇人。
while在句首能表轉折嗎,舉幾個例子
樓上,can 後麵怎麼加成doing了!!表誤人子弟……The soles are leather, while the uppers are canvas.鞋跟是皮的,而鞋麵是帆布的While he loves his students, he is very strict with them.雖然他愛他的學生, 可是他對他們很嚴格。
本句中while 是表示轉折關係嗎?我感覺有些翻譯不通,如何譯呢?
在這裏,根據語境,while沒有轉折的意思,應該翻譯成同時。
當係統用戶忘記密碼時,提供新的密碼會帶來額外的消耗;同時如果用戶們被迫頻繁更換密碼的話,他們往往會將其寫下來,這樣會使係統更加不安全。
making systems even less secure是現在分詞短語做伴隨狀語。
while到底是並列關係的並列連詞還是轉折
while後的句子謂語動詞並不一定是ing形式,具體需要根據上下文和時態來定,while後的句子時態可以是一般現在時,也可以是過去時態、進行時態等。
while的具體用法如下:1、“當……時候”, 引導時間狀語從句(從句動作必須是延續性的)。
Please don't talk so loud while others are working. While I was cleaning the window,my finger was seriously cut.2、“雖然,盡管”相當於although,引導讓步狀語從句(常把while放在句首)。
While she is a top student, she has some shortcomings. While the Internet is bridging the distance between people, it may also be breaking some home or will cause other family problems.3、“隻要,如果”等於as long as,引導條件狀語從句。
There is hope while there is life. While you study hard, your effort will pay off.擴展資料:1、 He was lost in the con-templation of the landscape for a while.有一會兒,他怔怔地注視著周圍的景物。
2、He rented out his house while he worked abroad.他在國外工作期間把自己的房子租了出去。

老師,請問while後麵要接什麼詞?可以在詞前加上we嗎?
一、while作名詞用,表示“一會兒”“一段時間”1.She likes to lie down for a while after lunch.她喜歡午飯後躺一會兒。
2.Coming to another country to study requires a big adjustment and it takes a while to fit in.來到另一個國家求學,需要花一段時間來適應。
二、While作連詞(1)引導時間狀語1.We must strike while the iron is hot.趁熱打鐵。
2.While she was listening to the radio,she fell asleep.她聽著收音機睡著了。
(2)引起讓步狀語從句,意思是“雖然…但是….”、“盡管…但是…”(多放於句首)1.While he loves his students,he is very strict with them..雖然他愛他的學生,可是他對他們很嚴格。
2.While these experiments are interesting and useful,it is important to remember that they may not always tell us much.(BookIIIp125) 雖然這些實驗很有趣也有用,但是很重要的是要記住,這些實驗也可能不會告訴你很多。
(3)引起條件狀語,意思是“隻要”1.While there is life there is hope.隻要生命存在,就有希望。
2.While there is a way there is away.有誌者事竟成。
三、While作並列連詞用,意思為“而,然而”,表對比。
而but表轉折。
注意用心比較體會while與but的句中用意1.Some people waste food while others haven't enough.有些人很費糧食,然而有些人卻吃不飽。
2.The son was having a good meal at home,while the parents were working in the fields.兒子在家吃好飯而父母卻在田裏辛勤勞作。
3.I ought to have helped her,but I never could.我本該幫她但沒能。
4.Honey is sweet,but the bee stings.蜂蜜很甜,但蜜蜂有刺蜇人。
四.while,when,as的用法區別 都譯為“當…的時候”,區別為:when後的從句謂語動詞既可是延續性動詞,也可是短暫性動詞,而且還可作並列連詞,譯為“這時”。
但以下句型一定用when,作並列連詞:句型A:be about to do…when…正要做…這時(發生另一事) 句型B:was/were doing…when…正在…這時(發生另一事) 句型C:had done…when…剛要做…這時(發生另一事)1.We were about to set out when it began to rain.我們剛要出發天突然下雨了。
2.He had hardly sat down when his mobile rang.他剛一坐下手機就響了。
3.I was walking along the bank of the river when I fell into it.我正沿河岸散步突然掉進水裏。
while後的從句謂語動詞隻能是延續性動詞,強調主從句的兩個動詞同時發生;while也可作並列連詞,表示兩個動作的對比,譯為“而”“然而”。
as則表示兩個變化中的動作的同時性,譯為“一邊…一邊…”。
1.While his mother was cooking in the kitchen,the boy fell asleep in the chair.(在一個延續動作過程中發生另一個動作)2.He hurried home,looking behind as he went.他匆匆回家,邊走邊往後看。
while後是不是隻能跟句子?
(一)when既可表示某一點時間,也可以表示某一段時間 .在when引導的時間狀語從句中,其謂語動詞可以是延續性的,也可以是非延續性的,可與主句中的謂語動詞同時發生,也可在其後發生. 例如: 1、I was just reading a book when she came into my room.她走進我房間時,我正在看書. 2、Were you writing when the teacher came in?老師進來的時候,你在寫信嗎? 3、When he was a child he was always trying out new ideas.他小時候就常常試驗一些新的設想. (二)、while隻能表示某一段時間,不能表示某一點時間.在while引導的時間狀語從句中,其謂語動詞隻能是延續性的,而且也隻能與主句中的謂語動詞同時發生或存在. 例如: 1、While Jim was mending his bike,Lin Tao came to see him.正當吉姆修自行車時,林濤來看他. 2、You can't do your homework while you're watching TV.你不能一邊看電視一邊做家庭作業. (三)when和while的區別還在於:while引導的時間狀語從句多用進行時態,而when引導的時間狀語從句多用一般時態. 例如: 1、While they were talking ,the bell rang.正在他們談話的時候,上課鈴響了. 2、I was doing my homework when my mother came back home yesterday evening.昨天晚上媽媽回家的時候,我正在做家庭作 擴展資料: 1、若主句表示的是一個短暫性的動作,而從句表示的是一個持續性動作時,兩者都可用。
如: He fell asleep when [while] he was reading. 他看書時睡著了。
I met him when [while] I was taking a walk in the park. 我在公園散步時遇到了他。
2、若主、從句表示兩個同時進行的持續性動作,且強調主句表示的動作延續到從句所指的整個時間,通常要用 while。
如: Don't talk while you're eating. 吃飯時不要說話。
I kept silent while he was writing. 在他寫的時候,我默不作聲。
3、若從句是一個短暫性動作,而主句是一個持續性動作,可以 when 但不用 while。
如: When he came in, I was listening to the radio. 他進來時,我在聽收音機。
It was raining hard when we arrived. 我們到達時正下著大雨。
4、若主、從句表示的是兩個同時(或幾乎同時)發生的短暫性動作,一般要用 when。
如: I thought of it just when you opened your mouth. 就在你要說的時候,我也想到了。
至於什麼是短暫性動作,什麼是持續性動作,其實有個很簡單的規律。
就是如果是進行時態,一般是持續性的。
如果是過去式,一般是短暫性動作。
對於,填寫when還是while的問題,通常首先看主句和從句中的時態,再根據以上4個規律來判斷填寫那個單詞。
