  情態動詞Will

考研英語:語法大全(情態動詞-will,would,ought)

  可用于各人稱,表示“意志”、“意愿”、“決心”、“允諾”等。如:

  I will try.我愿一試。

  I will do my best.我一定盡力而為。

  We will never do it again.我們永遠不會再做此事了。

  Which will you fake?你要哪一個?

  Who will go with me?誰愿和我一同去?

  will在疑問句中用子第二人稱時

  這時句子表示說話人向對方提出請求或詢問。如:

  Will you please explain the sentence once more?請你再把這個句子解釋一遍好嗎?

  Will you have western food or Chinese food,Mr. Smith?史密斯先生,你吃西餐還是中餐?

  Will you pass me the butter?請你把黃油遞給我好嗎?

  注意下面句中的won't亦表請求:

  Won't you come in ?請進來好嗎?

  注一:在條件狀語從句中須用現在一般時表將來,但當will用作情態動詞表意愿時,則亦可用于條件狀語從句,如I'll be glad if you will come.(你如愿來,我將會很高興)。

  注二:will在下面句子中= I suppose(我猜想)或probably(大概)。如:

  This will be the room you are looking for.這大概就是你要找的那個房間。

  You will remember the story I told you the other day.你們大概還記得我那天給你們講的那個故事。

  注三:will有時表示一種習慣動作或狀態。如:

  Water will boil at 100 degrees Centigrade.水總是在攝氏100度煮沸。

  Boys will be boys.男孩子總是男孩子。

  情態動詞——would

  Would

  是will的過去式,可用于各人稱,表示過去時間的“意志”、“愿望”和“決心”等。如:

  He declared that he would do everything to help us.他說要盡一切可能來幫助我們。

  I told peter that I would go along wit him.我告訴彼得我要跟他一塊去。

  All in e doctors and nurses told Dr. Bethune not to give his own blood to the wounded, but he wouldn't listen.和護士勸白求恩大夫不要把自己的血輸給傷員,但是他不聽。

  would用來表示現在時間時

  這時would不論是表達說話人本身的意志或向對方提出請求,均較will婉轉。如:

  Would you tell us something about yourself?請跟我們談談你自己好嗎?

  Would you like to have a glass of wine?你要喝杯酒嗎?

  Would you please tell me the way to the nearest bus-stop?請告訴我去最近的公共汽車站怎么走好嗎?

  Would you mind helping me with my packing?請你幫我打打行李好嗎?

  注:在日常會話中,I would like to和I should like to都可以說,I would like的簡略式為I'd like.如:

  I should (would) like to have a look at the new television set.我想看看這架新電視機。

  I'd like to borrow a copy of Alice in Wonderland.我要借一本《愛麗絲漫游奇境記》。

  Would還可以表示過去習慣發生的動作

  I found that retired persons would often go to the park to play chess.我發現退休的人經常到公園里下棋。

  When he had a problem to solve,he would work at it until he found an answer.當他有個問題要解決時,他總是想辦法一直到找到答案為止。

  情態動詞——ought

  ought

  ought只有一種形式,后面須跟帶to的動詞不定式。Ought表示“有義務或必要”做某件事,還可表示“勸告”。如:。

  You ought to follow the old man's advice.你應當聽那位老人的話。

  You oughtn't to smoke so much.你不應當抽煙太多。

  You ought to go to the clinic at once. You don't look well.你臉色不好,應該馬上到醫務室去。

  注:ought表示“應該”,語氣比should強。

  ought后加動詞不定式的完成式時

  指過去的動作。如用肯定形式(ought to have done),表示某一件事該做而未做,相當于should have done.如用否定形式(ought not to have done),則表示一件不該做的事情發生了,相當于should not have done.如:

  He ought to have done the exercise more carefully.這個練習他應當作得更細心一些。

  I ought to have returned these books to the library last week.我上星期就應當把這些書還給圖書館。

  You ought not to have been so rude.你不該這樣粗魯。

  You ought not to have taken his skates without asking him.你不該沒有得到他的許可就把他的冰鞋拿走。
