  (1)other作形容词,通常用在单数或复数名词的前面,意为“别的;其他的.;另外的”。 I’ll come again some other day. 我改日再来。

  (2)others(=other+复数名词) 泛指“部分”含义,用于已知的一些人或物中,除去某些后余下的人或物中的一部分。

  The students of Class Four are cleaning the classroom. Some are carrying water,others are sweeping the floor. 四班的学生们在打扫教室。一些人在打水,另一些人在扫地。

  (3)the other

  the other表示已知的两个(或两部分)人或事物中,特指的“另一个”或“另一些”,其后可跟单数或复数名词。

  This composition is better than the others. 这篇作文比其他那些都好。

  (5)another泛指不定数中(三者或三者以上)的“另一个”。another前面不能用定冠词the,它作为限定词(定语)通常与单数名词连用,但是它后面可以跟few或基数词的复数名词。 This glass is broken,get me another please. 这只玻璃杯坏了,请给我再拿一个。 I’ll stay here in another few days. 我要在这儿再呆几天。

  注意:other和another都可以用来修饰数词,表示“另外的;附加的”,但是结构不同。other的位置是“数词+other+复数名词”,相当于more的用法;而another则是“another+数词+复数名词”。

  Me neither. = Neither/Nor have I. 我也没有。

  这是一个否定的省略句。它的结构是“ Neither/Nor + be动词/助动词/情态动词+主语”。而用在肯定的省略句中时要使用so,它的结构是“So+ be动词/助动词/情态动词”。如: I paid 20 yuan for this book.

  2 It was because I could speak English that I got the job.

  It’s + 强调成分+ that。。。

  Grammar

  1. 现在完成时

  (1) 用法:动作到现在已经完成或刚刚完成;

  过去发生或已完成的动作对现在造成的结果和影响;

  过去开始一直持续到现在的动作或状态。

  (2) 基本结构:have/has + V.过去分词

  (3) 时间状语:already, yet, just, ever, never, once, twice, so far, ever since, for a long time, for + 一段时间, since + 过去的时间点/过去时的从句,等。

  (4) 注意事项:

  A. 现在完成时是现在的时态,重点表达目前的结果和状态;

  B. 表示动作从过去开始持续到现在用for + 时间段, since +点时间连用。对for与since短语提问用how long。

  C. 现在完成时从不与when引起的疑问句联用。

  D. have been to:去过…

  have gone to:去了…

  have been in:呆在…

  E. 短暂性动词变为延续性动词:

  He has been an English teacher since three years ago.

  We have known each other since we came to study in this university.

  (2) for后接时间段

  He has lived here for three years.

  3. 现在完成时与一般过去时的区别

  现在完成时表示过去发生的某一动作对现在造成的影响和结果,强调的是现在的情况,所以它不能和表示过去的时间状语连用,如:yesterday, last night, three weeks ago, in 1990等。 而一般过去时只表示过去的动作或状态,和现在不发生了关系,它可以和表示过去的时间状语连用。如:

  He has lived here since 1992. 1992年以来他一直住在这里。(他现在还住在这里) He lived here in 1992. 1992年他住在这里。(并不涉及他现在是否住在这里)

14. keep on doing sth.

三、重点语法:

【反身代词】英语中共有八个反身代词,在使用时应注意和它所指的相应的对象在人称、性别、数上保持一致。

数 人称:第一人称/第二人称/第三人称

单数:myself/yourself/himself herself itself

复数:

ourselves/yourselves/themselves

反身代词的用法:

1. 可用作宾语,指的是宾语和主语表示同一个或同一些的人或事物。

如:Maria bought herself a scarf. We must look after ourselves very well.

2. 可用作表语,指的是表语和主语表示同一个或同一些人或事物。

如:She isn’t quite herself today.

3. 可用作主语或宾语的同位语,常用来加强语气。

如:She herself will fly to London tomorrow. I met the writer himself last week.

4. 用在某些固定短语当中。

如:look after oneself / take care of oneself 照顾自己

teach oneself sth./ learn sth. by oneself自学

enjoy oneself 玩得高兴,过得愉快

help oneself to sth 请自用……(随便吃/喝些……).

hurt oneself 摔伤自己

say to oneself自言自语

leave sb. by oneself把某人单独留下

buy oneself sth.给自己买……东西

introduce oneself 介绍……自己

【提醒】

1. 反身代词不能单独做主语,但可以做主语的同位语,起强调作用。如:我自己能完成作业。

(误)Myself can finish my homework.

(正) I myself can finish my homework.

I can finish my homework myself.

2. 反身代词表示“某人自己”不能表示“某人的东西”,因为它没有所有格的形式。表达“某人自己的(东西)”时,须要用one’s own.

如:我用我自己的蜡笔画画。

(误)I’m drawing with myself crayons.

(正) I’m drawing with my own crayons.
