篇一:after的用法

after的用法

1. 用作连词是词,它引导的时间状语从句如果具有将来意义,往往要用一般现在时来表示(有时也用现在完成时),而不能直接用一般将来时。如:

误:I’ll tell him after you wil leave.

正:I’ll tell him after you leave (或have left). 你走了之后我再告诉他。

注:(1) 具有以上性质的时间连词还有when, as soon as, until 等以及条件连词if。

(2) 选择一般现进或现在完成进(表示将来意义)的基本原则是:如果强调从句 动作在主句动作之前完成,则用现在完成时;如果强调主从句动作 同时发 生,或几乎同时发生(尤其是当从句的谓语动词是get, arrive, see, hear, leave, return等表示迅速完成的动作的动词时),多用一般现在时(有时 两种时态都可以)。如;

I’ll leave when he comes back. 他回来后我就离开。(from )

I will give my opinion when I have read the book through. 我把书看完了再提意见。 We’ll leave as soon as it stops (或has stopped) raining. 雨停我们就动身。

2. 一般说来,如果在过去某一时间内先后发生了两个动作,那么先发生的动作用过去完成时,后发生的动作用一般过去时。但是若用连词after 来连接这两个动作,由于after本身已说明了两个动作的先后关系,所以两者均可用一般过去时。如:

After he (had) closed the door, he left the house. 关了门之后,他就离开了家。 注:类似这种性质的时间连词还有before, as soon as等。

3. 有时以连词after引导的时间状语从句可以换成一个以介词after引导介词短语或以连词after引导的分词短语,而意义不变。如:

He went to school after he had breakfast (=after breakfast). 吃了早饭之后,他就去上学了。

After l had finished (=After having finished / After finishing / Having我干完活后就去睡觉了。

4. after还可用作副词,意为“后来”或“(一段时间)以后”,通常要放在另一时间副词之后。如:

We arrived soon (或just / shortly) after. 我们不久就到了。

He returned twenty years after. 20年后他回来了。

注:(1) 在非正式文体中,after也可放在其它词之后。如:

We had dinner and went home after. 我们吃了饭,后来就回家了。

(2) two days after=after two days=two days later.

after与in的区别

1. 这两词均可与时间段连用,表示“在??之后”,但after 指的是以过去时间为起点的一段时间以后,因此常与过去进连用,而in指的是从现在算起的一段时间以后,因此要用于将来时或含有将来意义的句子。如:

He came back after three days. 他3天后回来了。

I’ll come back in three days. 我3天后回来。

I think he can come back in three days. 我想他3天后可以回来。

2. after 还可与时间点连用(in不能这样用),此时可用于将来时。如:

He will arrive after four o’clock. 他4点钟以后到。(from )

3. after 还可与某些表示活动的名词连用,表示“在??之后”(in不能这样用)。 如:after school after the meeting(放学后),(散会后)。

advice的用法

1. 表示“劝告”、“忠告”、“建议”,是不可数名词,若要表示一条或几条建议或劝告,则说a piece / three pieces of advice 一条 / 三条建议。

2. 表示按照某人的意见做某事,一般用介词on 或by。如:

It was done on (或by) my advice. 这是按我的意见做的。

3. 表示提出建议或忠告,一般用动词give;表示向某人请教或征求意见,一般用动词ask / ask for; 表示接受意见或劝告,一般用动词take / follow。如:

He gave us good advice on how to learn English.

他对怎样学习英语给我们提出了很好的建议。

He asked (for) the teacher’s advice. / He asked the teacher for his advice. 他向老师请教。

If you take (或follow) my advice and study hard, you’ll pass the examination. 如果你听我的劝告用功读书,你就会考及格。(from )

4. advice 还可表示“消息”、 “报道”,此时多用复数形式。the latest advices(最新报道)。

afraid的用法

1. afraid 是形容词,而不是动词,并且只能作表语而不能作前位定语。如: 误:He afraids. / Don’t afraid. / He is an afraid man.

正:He is afraid . 他怕。/ Don’t be afraid. 别害怕。

2. 一般认为afraid 可用much 或very much, 而不用very修饰。如:

He is (very) much afraid of dogs. 他很怕狗。

但在现代英语也有very afraid的说法。

3. afraid 一般要放在be之后作表语,而不放在 feel 之后。如:一般说I feel afraid.

4. be afraid 的主语一般不能是无生命的东西。如:

误:It’s afraid that we may be late. (from )

正:I’m afraid (that) we may be late. 恐怕我们会迟到。

5. be afraid 之后若接一个含有否定意义的从句时,其否定不能转移到主句上。 (这点与hope, wish, fear 等词的用法类似,但与think, believe, suppose 等词的用法相反。)如;

误:I’m not afraid that I can go.

正:I’m afraid the I can’t go. 恐怕我不能去。

注:省略句 I’m afraid not (恐怕不行。)也不能说成I’m not afraid. 如:

A:Can you do it yourself? 你自己能做吗?

B:I’m afraid not . (=I’m afraid that I can’t do it. ) 恐怕不行。

across, along, through的区别

along 表示循着一条水平线或狭长的事物运动,意为“沿着”;across表示从平 面的一边到另一边,意为“横过”;through表示从立体空间的一端进去,另一 端出来,意为“穿过”。如:

I saw him running along the road. 我看见他沿着这条路跑。

Can you swim across the river?你能游过河去吗?

He walked through the forest alone. 他独自穿过森林,

注:(1) 与抽象名词连用,一般只用through。如:(from )

He became richer and richer through hard work. 他通过勤奋劳动变得越来越富有。

(2) 在美国口语中,可用from ?through 表示“从??到”(此时不用along 或across)。如:

from Monday through Saturday从星期一到星期六

accept与receive的区别

1. receive 指“收到”、“接到”。表示一种被动的行为;而accept 指“接受”,表示的是一种主动的行为,并伴随有一种满意或允诺的意味。试体会:

He received the present, but he didn’t accept it.

他收到了礼物,但没有接受。

2. 两者之后均可接名词或代词作宾语,但不可接不定式。如:

He asked her to marry him and she accepted him.

他向她求婚,她同意了。

但:不可说?she accepted to marry him. (from )

3. 表示“接见”、“接待”时,应用receive,不用accept .

She was warmly received. 她受到热情接待。

4. 表示“从??收到接爱??”时,两者之后均可接from。

He received / accepted an invitation from his friend. 他收到 / 接受朋友的邀请。

about, round, around的区别

1. 表示“……周围”,三者常可互换。如:

注:在现代英语中,about 用于这种情况已不多见。

2. 表示“到处”,三者常可互换。如:

He travelled about (或round / around) the world. 他周游全世界。

3. 用在数字之前表示“大约”,一般用abut或 around。如:

It costs about (或around) ten dollars. 大约要花10美元。

注:在英国英语中,在表示时间的词组里也可用round。如:

He arrived about (或round / around) 5 o’clock. 他是大约5点钟到的。

I’ll be back about (或round / around) lunch time. 我午饭前后回来。(from )

4. 表示把某物分给一群人中的每一个时,可用round 或around, 而不用about。如: Will you hand round (around) the papers? 请你把考卷分发一下

篇二:A.acrossB.alongC.clownD.through

一、整体解读

试卷紧扣教材和考试说明,从考生熟悉的基础知识入手,多角度、多层次地考查了学生的数学理性思维能力及对数学本质的理解能力,立足基础,先易后难,难易适中,强调应用,不偏不怪,达到了“考基础、考能力、考素质”的目标。试卷所涉及的知识内容都在考试大纲的范围内,几乎覆盖了高中所学知识的全部重要内容,体现了“重点知识重点考查”的原则。

1.回归教材,注重基础

试卷遵循了考查基础知识为主体的原则,尤其是考试说明中的大部分知识点均有涉及,其中应用题与抗战胜利70周年为背景,把爱国主义教育渗透到试题当中,使学生感受到了数学的育才价值,所有这些题目的设计都回归教材和中学教学实际,操作性强。

2.适当设置题目难度与区分度

选择题第12题和填空题第16题以及解答题的第21题,都是综合性问题,难度较大,学生不仅要有较强的分析问题和解决问题的能力,以及扎实深厚的数学基本功,而且还要掌握必须的数学思想与方法,否则在有限的时间内,很难完成。

3.布局合理,考查全面,着重数学方法和数学思想的考察

在选择题,填空题,解答题和三选一问题中,试卷均对高中数学中的重点内容进行了反复考查。包括函数,三角函数,数列、立体几何、概率统计、解析几何、导数等几大版块问题。这些问题都是以知识为载体,立意于能力,让数学思想方法和数学思维方式贯穿于整个试题的解答过程之中。

知识点归纳:介词across, along, through的区别

1. across 和 through 都可表示“横过”或“穿过”,前者主要表示从某物的表面“横过”,涉及“面”的概念;而后者则表示从某个空间“穿过”,涉及“体”的概念。如: He walked across the road carefully. 他小心地走过马路。 He walked through the forest alone. 他独自一人走过森林。

有时 across 表示“横过”也可在“体”内进行,但此时它仍与through 有差别:前者表示从某个“体”的一端到另一端,而后者表示穿过两端。如:

He walked across the hall. 他从大厅的一端走到另一端。 He walked through the hall. 他穿过大厅。 2. along 表示“沿着”,通常用于狭长的东西。如: I saw him running along the road. 我看见他沿着这条路跑。 We walked along the river. 我们沿河散步。 3. 注意以下习惯用法:

(1) 与抽象名词连用,表示“通过”,一般只用 through。如: He became richer through hard work. 他勤奋致富。

(2) 在美国口语中,可用 from ... through 表示“从……到”(此时不用along 或 across)。 We work from Monday through Saturday. 我们从星期一到星期六工作。 知识点归纳: hear sb. to do sth. 和 hear sb. doing

用动词原形表示"听见...做了某事"强调动作的全过程,表示经常做或动作已经完成;用-ing形式表示"听见...在做某事"强调动作正在进行!

四、 巩固练习
