2)both用作代词。常位于连系动词之后，或实义动词之前；但若当动词是由几个部分组成时，both则放在第一个助动词之后。此外，它可用作主语。如：
①They are both absent. (同位语)他们俩都缺席。
②They both agree to stay. (同上)他们俩都同意留下来。

在有关从句的句子里，我们在way后面常用that来代替in which。
例如：
③I like the way (that) she organized the meeting. 我喜欢他组织会议的方法。
2)way后面可跟“带to的动词不定式”结构，也可跟“of+ -ing”结构。两者之间没有重要区别。例如：
①There's no way to prove he was stealing money. 无法证明他在偷钱。
②There's no way of proving he was stealing money.
无法证明他在偷钱。
3)不要混淆in the way和on the way：in the way是用来谈障碍--------阻止你到想去的地方的人或物；on the way意为“在途中”。试比较：
①Please don't stand in the kitchen door----you're in the way.
请不要站在厨房门口--------你挡了我的路。
②Let's not stop too often on the way. 咱们别老在途中停留了。

①The desks and chairs are made of wood. 这些课桌都是木头制成的。
②The cloth is made of cotton. 这种布是用棉花制成的。
3)be made from 表示制成的东西完全失去了原材料的外性和特性，原料在制作过程中发生了化学变化，从成品已无法辨认。如： ①Gas is made from coal. 煤气由煤制成。

=We can make flour into bread.
=We can make bread (out) of flour.
2．help oneself 的用法
help oneself是固定用法，可单独使用，也可和介词to连用。主要有四种含义：

“别客气(随便喝吧)！”
③“Jill, help yourself to the pancakes. They are delicious”. 吉尔(自己)拿些煎饼吃吧！非常好吃！
2)take for (oneself), esp. dishonestly, 擅自取用。此时，to后宾语不一定是食物类，而可以泛指其他各种物品。如：

②Before leaving, father warned me against not to help myself to the medicine in the box on the shelf. 出门前，父亲再次警告我不要拿放在架子上盒子
里的药。
【注意】 help sb to sth表示“替别人取食物等。”如：
①May I help you to some more meat? 我帮你再拿些肉好吗？
3．动词时态和by引起的时间状语
by引导的时间状语，有“在某时前、到某时为止”、“到某时”的意思，所修饰的谓语动词的时态既取决于by短语，指过去、将来还是现在，也取决于谓语动词是动作动词还是状态动词。详述如下：
1)by引导的时间状语表示过去某一时间
(1)如谓语动词是动作动词，该动作到by短语所示时间时已经完成，则用过去完成时。如：
①By the time he was ten, he had already built a chemistry lab for himself.
到了十岁时，他为自己建了一个化学实验室。
(2)如谓语动词是动作动词，该动作到by短语所示时间时尚在进行之中，则用过去进行时。如： ①By seven o'clock, the wind was blowing harder than ever.
到七点时，北风比以往吹得更强劲了。
(3)如谓语动词是状态动词，表示到by短语所示时间时存在的状态，则用过去时。如：
①By that time the Japanese were already very near.
到那时，日本人已经很近了。
②By then he knew what he wanted to be when he grew up.
到那时，他知道他长大后要干什么。
(4)如谓语动词是状态动词，表示到by短语所示时间时该状态已延续若干时间，则用过去完成时。这时，另有一个表示一段时间的状语，说明该状态延续的时间长度。如： ①By the end of last month, my brother had been on that ship for two years.
到上月底，我兄弟在那艘轮船上已有两年了。
2)by短语表示将来某一时间
(1)谓语动词如果是动作动词，则用将来完成时或一般将来时，表示到by短语所表示的时间时该动作将完成。如：
①Quite 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.
你常常会发现，那个不认识的单词会再次出现，也许会多次出现。到全章快读完时，你就会猜出这个词的意义了。
②We will have the work completed by noon tomorrow.
到明天中午我们将把工作做完。
在主动词为过去式的宾语从句中则用过去将来时。如：
③Mrs Adams thought the movie would be finished by 10:30 p. m. 亚当斯认为电影到晚上十点半会结束。
(2)如谓语动词是状态动词，则用一般将来时，表示到by短语所示时间将出现的状态。如：
①Your son will be all right by supper time.
到吃晚饭时你儿子(的病)就会好了。
②He won't be here by this time tomorrow.
明天这个时候他还不会到这里。
3)by短语表示现在
如谓语动词是动作的动词，则用现在完成时，表示到现在该动作已完成。如： Perhaps she's recovered by now. 也许现在她已恢复健康了。
4．be able to与can的用法区别
be able to表示能力，意思上与can没有区别，但can只有现在式和过去式(could)，而 be able to则有更多的形式，体现在be的时态变化上。例如：
①No one is able to do it. (= No one can do it.) 没人能做这件事。
②We shall be able to finish the work next week.
我们下周将能完成这项工作。
③I haven't been able to find the book. 我没能够找到那本书。
常用句型结构
1．as…as…中第一个as是副词，第二个as是连词，其基本用法如下：
1)如果我们要说两个东西在某方面是一样的，同我们就可以用as…as… 加一个原级形容词或副词。如：
①It's as cold as ice. 它象冰一样冷。
②He drove as fast as he could. 他尽可能快开。
在非正式文体中，第一个as往往省略。美国英语尤其如此。例
如：
③She's bard as mails. 她冷酷无情。
如果第二个as后面跟的是人称代词，可以用主格(I，he，we等)，也可以用宾格(me，him，us等)。在正式的文体中多用主格(as clever as I)，但在非正式的讲话或文字中，宾格较为普通(as clever as me)。
【注意】在作否定的比较时，可用not as…as…，也可用not so…as…。在现代英语中，两者都是正确的。例如：
④She's not as/ so nice as her sister. 她不如她姐姐好。
2)如果涉及数量，我们可以用as much …as…或as many …as…加一个名词。
例如：
①I haven't got as much money as I thought.
我没有原来想象的那么多钱。
②We need as many records as possible.
我们需要尽量多弄到一些唱片。
▲as much和 as many也可用作代词，后面不跟名词。如：
③I ate as much as I could. 我放开肚子大吃了一顿。
④He didn't catch as much as he'd hoped.
他没有得到预期的那么多。
▲as much还可以用作状语，来修饰某个动作或状态。如：
⑤You ought to rest as much as possible. 你应当尽量多休息。
3)as…as还可以与twice，three times等连用，也可以与half，a quarter等连用。例如：
①I'm not going out with a man who's twice as old as me.
我不愿意和一个年纪比我大一倍的人一起参加社交活动。
②We got three times as many people as expected.
来的人超过我们预料人数的两倍。
③You're not half as clever as you think you are.
你可不象自己想象的一半那么聪明。
2．“too…to…”意为“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，酒馆不会营业了。
③It's too heavy for you to lift. 太重了，你提不起来。
【注意】当glad，eager，easy，pleased等形容词放在“too…to…”结构中的“too”后时，其后的不定式短语往往含有肯定意义。例如：
①I am too eager to join the Youth League. 我非常渴望加入共青团。
②I am too glad to meet you. 见到你我非常高兴。
3．感叹句的两种形式
感叹句由 What或 How引导。What后接名词；How后接形容词或副词。构成以下句型：What＋a(an)＋(adj.)＋可数名词单数；What＋(adj.)＋可数名词复数或不可数名词以及How＋(adj. ＆ adv). ＋句子。例如：
①What an interesting film we saw yesterday!
昨天我们看的电影真有趣！
②What delicious beancurd you offered me!
你给我的豆腐真好吃！
③How delicious the soup is! 这汤真香！
④How hard the farmers are working in the fields!
农夫们在田野里干得多起劲！
