知识梳理 人教版七年级英语下册unit3解析词汇、句型解析及练习

Kate is no teacher.(=Kate is not a teacher.) 凯特（根本）不是教师。 注意：no也可以修饰形容词比较等级，表示“完全不，根本不”的意思。例如： I'm feeling no better than yesterday. 我一点儿也不觉得比昨天好。 7. like

1）like 作动词，意为“喜欢，想要”，反义词是dislike或hate。后面可以跟名词，动词不定式或者动名词等。例如： I’d like some noodles. 我想吃些面条。 My father likes watching TV after supper. 我爸爸喜欢在晚饭后看电视。

She likes flowers very much. 她很喜欢花。

注意：like后跟to do 时，表示“某一次的喜好或者倾向”；后跟doing时，表示一贯的习惯或者爱好。例如：

She likes doing her homework after supper, but today she likes to watch TV.

她晚饭后一般喜欢做作业，但是今天她想看电视。

2）like 作介词，意为“如同，像”，反义词是unlike。用于“be like +名词或代词”时，意为“像……”；构成“look like”时，意为“看起来与……相像”。例如： The baby is like his mother. 这个小婴儿长得像他妈妈。 He looks like a teacher. 他看上去像个老师。 8. cross

1）cross 作动词， 意为“横过，越过”，指从表面上横过。例如： They cross the river every day. 他们每天都要过河。

Cross the road, you will see the store. 过了马路，你就会看到那个商店。 2）cross 作名词，意为“十字架，十字形饰物；画十字的动作”。例如： Jesus died on the cross. 耶稣死在十字架上。

He made a cross over his head. 他在他头上画了一个十字。 拓展：across和cross的区别

这两个词都是“横越, 横跨，横穿”的意思，但是cross是动词可以单独作谓语；但是across是介词，需要和动词一起构成谓语。例如： They cross the street to go to school every day. 他们每天横过马路去上学。

They walk across the street to go to school every day. 他们每天步行横过马路去上学。 9. stop

1）stop 作动词，意为“停止，中断，阻止，阻拦”等意。既可以做及物动词，也可以做不及物动词。例如： The car stopped. 车停了。

The guard stopped me at the gate. 卫兵在大门口将我拦住。 2）stop 作名词，意为“停止; 逗留，车站”等。例如： I will wait for you at the bus stop. 我会在公共汽车站等你。 He slowed the car almost to a stop. 他放慢车速，车几乎停住了。 10. dream

1）dream 作动词，意为“做梦，梦见，渴望，向往”等意，既可以做及物动词，也可以做不及物动词。意为“做……梦“时，后跟同源名词dream做宾语；意为“梦见”时，常和about连用；意为“渴望、向往、考虑”等时常和of连用。例如： She dreams a good dream every night. 她每晚都做美梦。

I sometimes dream about my good friends. 我时常梦见我的好朋友。 I dream of becoming a teacher. 我渴望成为一名教师。

2） dream 作名词，意为“梦，愿望，心愿”等。例如：

It's my dream to win a Nobel Prize. 我的理想是获得诺贝尔奖。 Your dream has come true. 你的愿望变成了现实。 11. 11-year-old

11-year-old, 是一个复合形容词。复合形容词的构成方法有很多，“基数词+名词（不用复数），中间用连字符隔开，就构成复合形容词的一种，表示时间、度量等。可以在句子中充当定语修饰名词。例如： a 10- year-old boy 一个10岁的男孩儿 a two-day conference 为期两天的会议 a 3-hour journey 一次3小时的旅程 a three-mile walk 一段三英里的步行 a two-hour exam. 一次两小时的考试 12. hundred

hundred是数词，意为“百”，当表示具体的“几百”时，用“基数词 + hundred”，注意不加-s。例如：

There are nine hundred students in our school. 我们学校有900名学生。 拓展:

1）hundreds of 表示“数百，成百上千的”这时hundred后要加-s，且后面有介词of，但是不能与数词连用。例如：

There are hundreds of people in the restaurant. 在餐馆里有成百上千的人。

2）表示数词的还有thousand“千”，million“百万”，billion“十亿”。它们的用法和hundred一样，可以用来表示约数和确数。例如：

There are thousands of people are waiting to see the movie star.

数千人在等着见那个电影明星。 练一练：
