发布时间:2016-3-11 编辑:互联网 手机版

1.介词between和among的用法及区别

1)between(prep)“在(两者)之间”;一般只指在两者或两部分之间。例如:

①There is a profound and lasting friendship between China and Korea.

中朝两国之间有深厚和永恒的友谊。

②The Yalu River flows between China and Korea.

鸭绿江介于中朝两国之间。

【注意】偶尔between也可用来指三个或三个以上之间,这种情况实际上

仍是指其中一个和其他中间的一个之间的关系。如:

③Laos lies between China, Burma, Thailand, Cambodia and Vietnam.

老挝位于中国、缅甸、泰国、柬埔寨和越南之间。 ④The friendly relations between the peoples are profound and lasting.

各族人民之间的友好关系是深厚的和永恒的。

2)among(prep)“在……中间”;表示在三个或三个以上的人或物中间,后面通常接集体名词或可数名词复数形式。例如:

①I saw him among the crowd. 我看见他在人群中。

② He came from a village among the hills. 他来自群山中的一个村庄。

2.while[wail]的用法

1)while可以用作并列连词,表示对比意义,译为“而”,“却”。例如:

①Instead, he asked his father why he was not able to hatch chickens, while hens could. 他反而问他父亲为什么他不能孵小鸡,而母鸡却能。

②Jane was dressed in blue, while Mary dressed in red.

珍妮穿蓝色衣服,而玛丽却穿红色衣服。

2)while还可以用作从属连词,作“在……期间”,“当……时候”讲,使用时应注意它与用作从属连词的when的区别:

when引导的时间状语从句,即可表示“一段时间”,又可表示“一点时间”,因此从句的谓语动词既可以是延续性的,也可以是非延续性的。如:

①I hope to see you when(while)I stay in Beijing on business.

(一段时间)当我出差北京时,希望见到你。

②When the clock struck twelve, all the lights went out.

(一点时间)当钟敲响十二下时,灯全部熄灭了。

【注意】while引导的时间状语从句只能表示“一段时间”所以 while从句的谓语动词应是延续性动词(或状态动词)。例如:

①While I stayed(or was) in Shanghai, I saw her three times.

我在上海期间见到她三次。

如果从句的谓语动词是延续性的,可以用while也可以用when。例

如:

②While(When) we were having a meeting, a stranger came in.

我们在开会时,一个陌生人走了进来。

3.still, yet和already的用法比较

1)still表示某事仍在进行中,意为“仍然”,“还”。例如:

①I am still busy, I have not finished my work yet.

我仍然很忙,我没有干完这个活儿。

②How to take some useful things out of the waste materials and use them again is still a big problem. 怎样从废料中提取有用的东西并加以重新利用

仍然是个大问题。

2)yet作“已经”解时,通常用于疑问句或否定句;作“还,仍然”解时,与not 连用,表示还没有。

3)already的意思是“已经”,通常用于肯定句。例如:

①They have already made full use of the waste water.

他们已经充分利用了废水。

4.助动词do的用法

在肯定句中,为了避免重复出现前面已经用过的某个动词时,通常用

助动词do。例如:

①It's important to listen to people carefully, and I usually do.

仔细倾听别人的意见是重要的,我通常也是这样做的。

5.over和across和区别

1)over和across都可用来表示“向(或在)某一长形物体如街道、马路、河流的另一边。”

①We walked over/across the road. 我们走过马路。

②He lives just over/across the river? 他就住在河对面。

【注意】over可用于水面上动作,不能用于水中动作。

④If we can be over/across the mountain before sunrise, there will be hope to win. 如果日出前我们能翻过那座山,就有希望获胜。

【注意】表示“越过”某一高形物体,用over与动词搭配,不用across。

3)across可用来表示从某一范围的一边到另一边,如田野、沙漠、房间等。

⑦He walked across the room, smiling strangely.

6.however的用法

作副词时可放在句首,句中或句尾,但是要用逗号隔开。在句首时逗号与在它后面,在句尾时逗号在其前面,在句中时,其前后均用逗号隔开。

与but的区别是:but语气不如however强,且不需要加逗号隔开。例如:

①It's raining hard. However, I think we should go to school on time. 雨下得很大,但我认为我们仍然要按时去上学。

②She waited, however, for no answer.

她仍在等,尽管没有回音。

③The students thought they had done everything as the teacher did. They were mistaken, however. 学生们认为他们已经按老师的要求做到了,然而他们错了。

4.for example与such as的用法及区别

①The farm grows various kinds of crops, such as wheat, corn, cotton and rice.

这个农场种植各种各样的庄稼,例如麦子,玉米,棉花和稻米。

【注意】

(1)such as一般不宜与and so on连用。

(2)对前面的复数名词部分起列举作用,一般不全部列出。故不可以说:

He knows four languages, such as Chinese, English, French and German. 应将such as改成namely, 后面加逗号。即:He knows four languages, namely, Chinese, English, French and German.

2)for example意为用来举例说明,有时可作为独立语,插在句中,不影响句子其他部分的语法关系。例如:

①A lot of people here, for example, Mr John, would rather have coffee.

6.a great many等表示“许多”的词语

英语中有许多词语可用来表示“许多”,根据性质可分为三大类。

1)修饰可数名词复数形式的有 many, a good/great many, quite a few, a large (或great)/small number of等,其后的谓语动词用复数形式。如:

①A great/good many words and expressions have come into the language from American English. 美国英语中的许多单词和短语进入了这门语言。

②Many have come to visit the old temple. 许多人来是为了看看古庙。

③Quite a few people didn't understand this. Very few would accept it.

有许多人不明白这一点。很少有人愿意接受。

④A great/small number of new factories have been set up in my hometown.

我们家乡建立了许多新的工厂。

▲many和few, a few在句中可作定语、主语,但不能作表语。如只能说I have many/few books, 而不能说 My books are many/few.

▲very many相当于a great/good many, 在程度上比many要强。

▲a number of修饰主语时,谓语动词用复数形式,the number of…作主语时,谓语动词用单数。如:

⑤A number of students have done the work well. 许多学生作业做得很好。

⑥The number of the students in our school has risen this year.

今年我们学校学生的数量上升了。

句⑤的 A number of作定语修饰主语 students。句⑥的介语短语 of the students in our school作定语,修饰前面的主语 the number, 表示特指,students 前的冠词the不能省。

2)修饰不可数名词的有much, a great deal of, quite a little, an amount of等。其后的谓语动词用单数形式。如:

①He has spent much/quite a little/a great deal of/a large amount of money on his new house. 他在新房子上花费了许多钱。

②Much/A great deal/Quite a little has been done to stop the noise.

已采取了许多措施来制止污染。

▲much, a great deal和 many一样,可作定语或主语,而不能作表语,我们一般说 He has much/a great deal of money, 而不说 His money is much(或a great deal)。

▲a great deal后面不接名词时,不能用介词of。

3)既能修饰可数名词,又能修饰不可数名词的有 a lot of, lots of, plenty of, a great quantity of等,谓语动词根据主语是可数或不可数决定单复数形式。如: ①There are a lot of/lots of people in that room. 那个房间里有许多人。

②There's a lot of/lots of rice in the bag. 那只口袋里有许多大米。

③They don't have plenty of(=enough)rooms to live in/food to eat.

他们没有足够的房间住/没有足够的食品吃。

常用句型结构

1.“主语+ have +(修饰语:no, little, some, much, great)等+difficulty/trouble +in + doing sth.”是一个常用的句型。例如:

①Everyone in the town knew him so we had no trouble/difficulty in finding his house. 镇上谁都认识他,因而我们毫不费事地找到了他的家。 ②We had great difficulty in building the house. 我们建房子费了很大劲。

③The students had some trouble in answering the question.

同学们回答这个问题有些困难。

④Do you have any trouble in finishing the work within two days?

两天内你完成这项工作有困难吗?

【注意】在使用这一句型时应注意以下四点:

1)difficulty/trouble为不可数名词,意为“困难”。

2)修饰语主要有no, little, some, much, great等。

3)句中介词为in,有时可省略。

4)介词in后必须跟动词的-ing形式。 2.I'd like to do something.是一个表示“愿意做某事”的常用句型。使用这一句型,应注意:

1)'d like是 should like和 would like的缩略式。常用来表示“愿意”之意,尤其是礼貌地提出邀请或愿意提供帮助时。like后可接名词或带to的动词不定式,但不接动词-ing形式。如:

①Would you like some bananas? 你想吃香蕉吗?

②Would you like to go there with me tomorrow?

明天你愿意和我一起去那儿吗?

【注意】用这种邀请句时,肯定回答用:“Yes, I'd love to.”否定回答用:

“I'd love to, but…”

③I'd like to see your ten-speed bicycle. 我想看看你们的十速自行车。

④Would you like to go to see the film this evening?

今天晚上你愿意去看电影吗?

⑤I'd love to, but I have a lot of work to do.

2)除would, should外,had也常缩写成'd形式。例如:

你最好穿上大衣,外面很冷的。

②He'd rather die than give up his beautiful wife.

他宁死也不放弃他漂亮的妻子。(would的缩略式)

【注意】would rather do something或would like to do something均表示主语的意愿,而had better do something则表示说话者的意愿。
