高三英語知識(shí)點(diǎn)1
look up the dictionary
漢語中的“查字典”，說成英語通常是 look up sth in a dictionary 或 consult [refer to] a dictionary。如：
I refer to the dictionary frequently. 我經(jīng)常查閱詞典。
You can look the word up in the dictionary. 你可以在詞典里查這個(gè)詞。
He often consulted a dictionary when he read the book. 他讀這本書時(shí)經(jīng)常查字典。
I looked the word up in the dictionary to refresh my memory of its exact meaning. 我查了詞典，以便弄清這個(gè)詞的準(zhǔn)確意思。
I often look up the words I don’t know in the dictionary or on the Internet. 我經(jīng)常在字典里或網(wǎng)上查找我不認(rèn)識(shí)的單詞。
“Is that the correct spelling?” “I don’t know—look it up in a dictionary.” “那是正確的拼寫嗎?”“我不知道——查查詞典吧?！?/p>
I didn’t know what “l(fā)oquacious” meant and had to look it up in a dictionary. 我不知道loquacious這個(gè)是什么意思，所以只好查了詞典。
有不少人認(rèn)為英語習(xí)慣上不能直接說 look up the dictionary, 其實(shí)這種表達(dá)在英語中也可以用，只是比較少見而已。例如：
I spend more time looking up the dictionary than reading the book. 我讀這本書時(shí)查字典的時(shí)間還多些?！?L. G. Alexander 編《新概念英語》(外研社)
Look up the dictionary and explain the meaning of the italicized words. 查字典然后解釋斜體詞的意思?！詮垵h熙編《高級(jí)英語》(商務(wù)印書館)

虛擬語氣在一些特殊詞中的使用或含蓄條件句
1.wish后的賓語從句。
與現(xiàn)在愿望不一致，用主語十過去時(shí)，例如：
I wi。hIwere you.
與過去愿望不一致，用主語+had+過去分詞，例如：Iwish I had visited the White House whenI was in the States與將來愿望不一致，用主語+would (could)+原形。
2.It's time句型：當(dāng)lt's tine后用that從句時(shí)應(yīng)該為主i吾+should+動(dòng)詞原形或主語十過去時(shí)，例如：It，s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當(dāng)于“How I wish+賓語從句”。
(l)If only he could come.他要能來就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather，as if(though)引導(dǎo)的從句也需使用虛擬語氣，表示過去的情況用過去完成時(shí)，表示現(xiàn)在與將來的情況用過去時(shí)，例如：
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虛擬條件句含蓄條件句是指句中沒有明顯的虛擬條件句，而是利用其他手段來暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來表示含蓄虛擬條件的手段有：
(1)介詞或介詞短語。如but for，but that，without,in case of, under more favorable condition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
注意：lest, for fear that和in case引起的從句中謂語動(dòng)詞多用should+動(dòng)詞原形，但也可以不用虛擬語氣，而用動(dòng)詞的陳述語氣形式。例如：The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說得很慢以免我們誤解。
(3)通過上下文及內(nèi)在含義，句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。
without, but. but for, otherwise引起的短語或句子常暗含著含蓄條件。例如：
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!

疑問代詞概說
"疑問代詞有who(誰，主格)，whom(誰，賓格)，whose(誰的，所有格)，what(什么)和which(哪個(gè)，哪些)等。
疑問代詞用于特殊疑問句中
疑問代詞一般都放在句首，并在句中作為某一句子成分。如：
Who is going to speak to us tomorrow?明天誰來跟我們講話?(who作主語)
Who told you so?是誰告訴你的?(who作主語)
Whom are you talking about ?你們在說誰?(whom作賓語，但在句首時(shí)口語常用who代替whom)
Whose umbrella is this ?這是誰的傘?(whose作定語)
What is that? 那是什么?(what作表語)
What did he say?他說什么?(what作賓語)
Which is yours，the blue pen or the redone?藍(lán)筆和紅筆哪一支是你的?(which作主語)
[注一]關(guān)于疑問代詞的各種用法，可參看77.70-77.72。
[注二]疑問代詞who，what，which等后面加單詞ever，可強(qiáng)調(diào)語氣，表達(dá)說話人的各種感情。如：
What ever do you want?你到底想要什么?
Who ever is she looking for ?她究竟是在找誰?
[注三]which表示在一定范圍之內(nèi)的選擇，what則沒有這種限制。如：
What do you usually have for lunch?你們午飯通常吃些什么?
Which do you like best?你最喜歡哪一個(gè)?
Which of you comrades come from the Northeast? 你們同志們中間誰是東北人?
疑問代詞可以引導(dǎo)一個(gè)間接疑問句
間接疑問句在句中可用作主語、賓語、表語等。疑問代詞本身在間接疑問句中又擔(dān)任一定的句子成分。如：
Who will be in charge of the work is still not decided.誰將負(fù)責(zé)這項(xiàng)工作，現(xiàn)在還沒有決定。(疑問代詞who引導(dǎo)一個(gè)主語從句，它本身又在從句中用作主語。)
Do you know what his name is?你知道他叫什么名字嗎?(疑問代詞what引導(dǎo)一個(gè)賓語從句，而它本身又在從句中用作表語。)
[注一] what所引導(dǎo)的名詞性從句(即主語從句、賓語從句、表語從句) 有時(shí)不是間接疑問句。如：
What he says is quite true.他所講的話很對(duì)。(what相當(dāng)于that which。它引導(dǎo)一個(gè)主語從句，這個(gè)從句不是間接疑問句。)
Children do what the nurse tells them to do.保育員讓孩子干什么他們就做什么。(what引導(dǎo)一個(gè)賓語從句，這個(gè)從句也不是間接疑問句。)
[注二] whatever，whoever，whichever等詞可引導(dǎo)名詞性從句。這些名詞性從句也不是間接疑問句。whatever，whoever，whichever也可引導(dǎo)表示讓步的狀語從句。見15.65和15.72)如：
They eat whatever they can find.他們找到什么就吃什么。(whatever引導(dǎo)一個(gè)賓語從句，并在從句中作賓語。)
I've got plenty of books 1eft.Whoever wants an extra copy can get one from me.我還剩下許多書，誰還想再要一本可來拿。(whoever引導(dǎo)一個(gè)主語從句，并在從句中作主語。)

in the end, finally, at last
三者均可表示“(經(jīng)過周折、等待、耽誤)最后，終于”之意。
不同的是：
finally 一般用在句中動(dòng)詞前面，而 at last 與 in the end 的位臵則較為靈活;
三者中at last 語氣最為強(qiáng)烈，且可單獨(dú)作為感嘆句使用。
After putting it off three times, we finally managed to have a holiday in Dalian.
At last he knew the meaning of life.
At last! Where on earth have you been?
But in the end he gave in.
另外，finally還可用在列舉事項(xiàng)時(shí)，引出最后一個(gè)內(nèi)容，相當(dāng)于lastly。
Firstly, we should make a plan; secondly, we should carry it out; finally we should make a conclu- sion.
