1)by引導(dǎo)的時(shí)間狀語(yǔ)表示過去某一時(shí)間
(1)如謂語(yǔ)動(dòng)詞是動(dòng)作動(dòng)詞，該動(dòng)作到by短語(yǔ)所示時(shí)間時(shí)已經(jīng)完成，則用過去完成時(shí)。如：
①By the time he was ten, he had already built a chemistry lab for himself.

到上月底，我兄弟在那艘輪船上已有兩年了。
2)by短語(yǔ)表示將來某一時(shí)間
(1)謂語(yǔ)動(dòng)詞如果是動(dòng)作動(dòng)詞，則用將來完成時(shí)或一般將來時(shí)，表示到by短語(yǔ)所表示的時(shí)間時(shí)該動(dòng)作將完成。如：
①Q(mào)uite often you'll find the unknown word comes again, perhaps several times and by the end of the chapter you'll have guessed its meaning.
你常常會(huì)發(fā)現(xiàn)，那個(gè)不認(rèn)識(shí)的單詞會(huì)再次出現(xiàn)，也許會(huì)多次出現(xiàn)。到全章快讀完時(shí)，你就會(huì)猜出這個(gè)詞的意義了。

3)by短語(yǔ)表示現(xiàn)在
如謂語(yǔ)動(dòng)詞是動(dòng)作的動(dòng)詞，則用現(xiàn)在完成時(shí)，表示到現(xiàn)在該動(dòng)作已完成。如： Perhaps she's recovered by now. 也許現(xiàn)在她已恢復(fù)健康了。
4．be able to與can的用法區(qū)別
be able to表示能力，意思上與can沒有區(qū)別，但can只有現(xiàn)在式和過去式(could)，而 be able to則有更多的形式，體現(xiàn)在be的時(shí)態(tài)變化上。例如：

我們下周將能完成這項(xiàng)工作。

常用句型結(jié)構(gòu)
1．a(chǎn)s…as…中第一個(gè)as是副詞，第二個(gè)as是連詞，其基本用法如下：
1)如果我們要說兩個(gè)東西在某方面是一樣的，同我們就可以用as…as… 加一個(gè)原級(jí)形容詞或副詞。如：
①It's as cold as ice. 它象冰一樣冷。
②He drove as fast as he could. 他盡可能快開。
在非正式文體中，第一個(gè)as往往省略。美國(guó)英語(yǔ)尤其如此。例
如：
③She's bard as mails. 她冷酷無情。
如果第二個(gè)as后面跟的是人稱代詞，可以用主格(I，he，we等)，也可以用賓格(me，him，us等)。在正式的文體中多用主格(as clever as I)，但在非正式的講話或文字中，賓格較為普通(as clever as me)。
【注意】在作否定的比較時(shí)，可用not as…as…，也可用not so…as…。在現(xiàn)代英語(yǔ)中，兩者都是正確的。例如：
④She's not as/ so nice as her sister. 她不如她姐姐好。
2)如果涉及數(shù)量，我們可以用as much …as…或as many …as…加一個(gè)名詞。
例如：
①I haven't got as much money as I thought.
我沒有原來想象的那么多錢。
②We need as many records as possible.
我們需要盡量多弄到一些唱片。
▲as much和 as many也可用作代詞，后面不跟名詞。如：
③I ate as much as I could. 我放開肚子大吃了一頓。
④He didn't catch as much as he'd hoped.
他沒有得到預(yù)期的那么多。
▲as much還可以用作狀語(yǔ)，來修飾某個(gè)動(dòng)作或狀態(tài)。如：
⑤You ought to rest as much as possible. 你應(yīng)當(dāng)盡量多休息。
3)as…as還可以與twice，three times等連用，也可以與half，a quarter等連用。例如：
①I'm not going out with a man who's twice as old as me.
我不愿意和一個(gè)年紀(jì)比我大一倍的人一起參加社交活動(dòng)。
②We got three times as many people as expected.
來的人超過我們預(yù)料人數(shù)的兩倍。
③You're not half as clever as you think you are.
你可不象自己想象的一半那么聰明。
2．“too…to…”意為“太……以致于不能……”。例如：
①He's too old to work. 他太老了，不能工作了。
②It's too late for the pubs to be open.
天太晚了，酒館不會(huì)營(yíng)業(yè)了。
③It's too heavy for you to lift. 太重了，你提不起來。
【注意】當(dāng)glad，eager，easy，pleased等形容詞放在“too…to…”結(jié)構(gòu)中的“too”后時(shí)，其后的不定式短語(yǔ)往往含有肯定意義。例如：
①I am too eager to join the Youth League. 我非常渴望加入共青團(tuán)。
②I am too glad to meet you. 見到你我非常高興。
3．感嘆句的兩種形式
感嘆句由 What或 How引導(dǎo)。What后接名詞；How后接形容詞或副詞。構(gòu)成以下句型：What＋a(an)＋(adj.)＋可數(shù)名詞單數(shù)；What＋(adj.)＋可數(shù)名詞復(fù)數(shù)或不可數(shù)名詞以及How＋(adj. ＆ adv). ＋句子。例如：
①What an interesting film we saw yesterday!
昨天我們看的電影真有趣！
②What delicious beancurd you offered me!
你給我的豆腐真好吃！
③How delicious the soup is! 這湯真香！
④How hard the farmers are working in the fields!
