Unit 1 Where did you go on vacation?

Section A 知识详解

1. something interesting有趣的东西

1)something,anything,nothing,everything是指物的不定代词。

somebody,someone,anybody,anyone,nobody,everybody,everyone是指人的不定代词。

somewhere,anywhere,nowhere,everywhere是指地点的不定代词。

2)当形容词修饰不定代词、不定副词时,放于其后;something special; somewhere wonderful.

3)不定代词、不定副词做主语时,谓语动词用第三人称单数。如:

Is everybody here? 大家都到齐了吗?

maybe

副词,意为“或许;大概”,常位于句首表推测。

Maybe he is at Jim's home.

或许他在吉姆家。

may be

由情态动词may和 be构成,意为“可能”,在句中作谓语。

He may be right.

他可能是对的。

6He plays at least twice a week.他至少一周踢(足球) 两次。

【解读】least adv.最小;最少 adj.& pron.最少的;最小的,它是little的最高级。at least 至少;不少于;起码,其反义短语为:at most 至多

At least he should say thanks. 他至少应该说声谢谢。

Section B重点知识讲解

1She says it's good for my health. 她说它对我的健康有益。

【解读】本句是一个含有省略that的宾语从句的复合句。She says 是主句,其后省略了thatit's good for my healthsays的宾语。

【解读】be good for ……有益 Exercise is good for you. 锻炼对你有益。

【拓展】be good at 在……方面做得好;擅长……

be good with 与……相处融洽 be good to 对……友好

2Although many students like to watch sportsgame shows are the most popular.

尽管许多学生喜欢观看体育节目,但是游戏节目仍然是最受他们欢迎的。

【解读】本句是复合句,although many students like to watch sports是让步状语从句。

【解读】although conj. 虽然;尽管;即使

相当于though,引导让步状语从句。

在英语中,although(though)but不能连用在同一个句中,即二者只能取其一。

Although he is tired,he didn't stop to have a rest.=He is tired,but he didn't stop to have a rest. 尽管他累了,但他没有停下来去休息。

3.It's good to relax by using the Internet or watching game showsbut we think the best way to relax is through exercise.

尽管通过上网或观看游戏节目对放松很有好处,但是我们认为锻炼是最好的放松方式。

【解读】本句是由but连接的并列复合句。前一个分句中,it是形式主语,真正主语是动词不定式 to relax by using the Internet or watching game shows;后一个分句中,we think后接的是一个宾语从句,省略了that

【解读】through prep. 以;凭借;穿过

He became rich through hard work and ability. 他凭借辛苦的工作和能力变得富有。

The sunlight was coming in through the window. 阳光穿过窗户照进来。

【辨析】through,across,over

through意为“穿过”,指从物体的里面穿过。

across意为“穿过”,指从物体的表面通过。

over意为“越过;跨过”,指越过一个有高度的物体。

They walked through the park after supper. 晚饭后他们穿过了公园。

I swam across the river and felt very tired. 我游过了河,感到很累。

Can you jump over the fence? 你能跳过篱笆吗?

4.Exercise such as playing sports is funand you can spend time with your friends and family as you play together. 像参加体育运动这样的锻炼是有趣的,并且你可以与你的朋友和家人一起花费时间进行锻炼。

such as 例如;像……这样 表示举例,相当于like。

5And remember“old habits die hard”请记住:旧习惯是很难摈弃的

【解读】die v. 消失;消灭;死亡

(1) 作“死亡”讲,是不及物动词,不能用于被动语态,强调动作,是瞬间动词,不能与表示一段时间的状语连用。

His grandfather died five years ago. 他祖父五年前去世的。  

(2) die可以用于进行时态,表示“即将死去,奄奄一息”。  

He is dying. 他快要死了。

6. However, she has some bad habits, too. 然而,她也有一些坏习惯。

【解读】however adv. 然而;不过

He said that it was so; he was wrong, however. 他说事情是这样的,但是他错了。

【辨析】 howeverbut

二者都有然而;但是之意,具体用法不同。however 副词,可以放在句首、句中或句末,置于句中时,前后通常用逗号隔开。

He wanted to go to the shopping mall, however, he didn't go at last.

他想去购物中心,但最后还是没去。

but并列连词,常常在句中,引导一个表示转折关系的并列句。

Mike is young, but he can do it well. 迈克虽然年龄小,但是他能做好那件事。
