Unit9 知识点总结

Section A

①---What’s your favorite subject?

---My favorite subject is science.

(1)favorite用作形容词时,意为“最喜欢的,特别喜欢的”,可在句中作定语修饰名词。注意:favorite与like都有“喜爱”的意思,但它们的磁性不同个,在句子中所处的位置也不同,favorite常与like...best互换作用。例如:

His favorite sport is basketball.= He likes basketball best.

What is your favorite color?= What color do you like best?

(2)favorite用作名词时,意为“特别喜欢的人或物”,是可数名词。例如:

These movies are my favorites.

②---Why do you like science?

---Because it’s interesting.

(1)疑问词why意为“为什么”,用来提问原因,其答句常用because引导的句子来回答。例如:

---Why are you late for school?

---Because it is raining.

(2)because是连词,意为“因为”,其后接句子,用来说明原因。在汉语中,表示因果关系一般用“因为……,所以……”,但在英语中,because(因为)与so(所以)在一个句子中不能同时出现。例如:

因为我太忙,所以我不能同你出去。

误:Because I am very busy, so I can’t go out with you.

正:Because I am very busy, I can’t go out with you.

正:I am very busy, so I can’t go out with you.

③---Who is your P.E.teacher?

---Mr Hu.

who是疑问代词,它引导的特殊疑问句对人提问,意为“谁”,可以作主语。who作主语时,用“who+谓语+其他?”的句型,并且who通常被认为是第三人称单数形式,谓语动词要与其保持一致。例如:

---Who helps you do housework?

---Mary.

who作表语时,用“who+be+主语?”的句型,系动词be随主语的数而变化:主语是第三人称单数时用is,主语是复数时用are。例如:

---Who’s this man?

---He’s Jack’s father.

---Who are these girls?

---They are Jean and Kate.

④He always plays games with us.

句中的play with...意为“和……一起玩”。例如:

Can you come out to play with me?

play with还可以意为“玩弄,玩耍”。例如:

The boy is playing with his toy car.

Section B

⑤---When is the class?

---It’s on...

介词on意为“在……时候”,常用于星期、日期前或用于前有描绘性修饰语或带有of 等引导的后置修饰语的morning,afternoon,evening,night,day前,也饿用于公共节假日前。例如:

I have a rest on Sundays.

What are you going to do on Monday morning?

He was born on the night of May 10th.

On Children’s Day, all the children are very happy.

⑥I’m really busy!

(1)busy是形容词,意为“忙的;繁忙的”,在句中可用作表语,也可用作定语。例如:

We are very busy now.

He is a busy man.

(2)busy的常用短语:

be busy doing sth.意为“忙于做某事”。例如:

He is busy doing his homework.

be busy with sth.意为“忙于某事”。例如:

My sister is busy with her lesson.

【提示】busy虽然有“忙”的意思,但busy只表示人“忙”,而不表示工作“忙”。所以主语一般用表示人的名词或代词,而不用work。

试译:我父亲的工作很忙。

误:My father’s work is very busy.

正:My father is very busy.

⑦It’s difficult, but interesting.

(1)difficult作形容词,意为“困难的,艰难的”。例如:

Nothing is difficult to a man who has will.

This question is too difficult for me.

(2)but是并列连词,意为“但是;可是”,表示转折意义。例如:

She’s very tall, but she doesn’t like playing basketball.

⑧I have an art lesson for two hours.

for为介词,后面加一段时间,表示“持续多久的时间”。例如:

I do my homework for three hours every day.

易错易混全解

1.特殊疑问句

(1)用来提出问题的句子,叫疑问句。疑问句按其所提出的不同问题可分为四种:一般疑问句、特殊疑问句、选择疑问句和反义疑问句。

特殊疑问句时以疑问代词或疑问副词开头,对句子中的某一部分进行提问的句子。它的基本结构是:特殊疑问词+一般疑问句语序。但是如果疑问词或由其所修饰的词在句子中做主语时,就用陈述句语序。回答时,针对问句中的代词或副词来回答,不用yes或no来回答。它的回答应是:问什么,答什么。

常用的特殊疑问代词有:what,which,who,whom,whose;疑问副词有:when,where,why,how等。

(2)特殊疑问句的构成有两种情况:

①当疑问词或其他修饰的词不作主语时,用疑问句语序,即疑问词+一般疑问句,这是最常见的情况。例如:
