人教版九年级Unit2知识点详解

（一）课文详解

1、What a great day!(P9)

本句是由what引导的感叹句。其结构为：What + a /an + 形容词+ 可数名词的单数形式（+主语+谓语+其他）

Eg: What a new bike(it is)! What a beautiful girl!

2、But I guess it was a little too crowded.(P9)

1)这是一个含有宾语从句的复合句，I guess为主句，it was a little too crowded为省略了引导词that的宾语从句。在复合句中，当主句为一般现在时时，宾语从句可根据其具体情况使用任意适当的时态。

Eg: I guess he is a policeman. I hear she went to Beijing by plane yesterday.

2)crowded adj.“拥挤的”。常用短语：be crowded with……“被挤满”。crowd v. “拥挤”

Eg: The shop near my house is always crowded with people.

Hundreds of people crowded into the church.

3、Bill wonders whether they’ll have zongzi again next year.(P9)

1)wonder此处用作既无动词“想知道”，相当于want to know. wonder在不同的句式中表达的意思不相同：

后接who,what,why等连接词引导的宾语从句及“疑问词+动词不定式”结构时，意为“想知道”

Eg: I wonder who that boy is.

后接if或whether引导的宾语从句时，表示一种委婉的请求或疑问

Eg: I wonder if I could use your mobile phone.

后接that引导的宾语从句以及动词不定式短语时，表示“对…感到惊讶”

Eg: I wonder to see her looking so cheerful.

wonder n.奇迹，奇观wonderful adj. 壮观的，奇妙的，精彩的

eg: What are the Seven Wonders in the world? We had a wonderful time in the park last Sunday.

2)whether连词，“是否，是不是”，引导宾语从句，相当于if。

Eg: He wonders whether / if it will be fine tomorrow.

辨析: whether if

二者都可以引导宾语从句，意为“是否”，一般情况下可以互换。

Eg: I don’t know whether / if she can work out the problem.

二者在引导宾语从句时，whether可直接与or not连用，而if不可以

Eg: I don’t know whether or not I should go.

if可以引导条件状语从句，意为“如果”，而whether不可以

Eg: If it doesn’t rain tomorrow, we will go camping.

if可以用于虚拟语气中，而whether不可以

Eg: If I were a bird, I would fly in the sky.

4、Bill and Mary believe that they’ll be back next year to watch the races.(P9)

believe此处用作及物动词“相信、认为”。其后既可以直接接名词、代词作宾语，也可以跟that等引导的宾语从句，还可以用believe sb to do sth的形式

Eg: I don’t believe you. I believe that he can win the match. I believe him to be an honest man.

当believe后跟宾语从句且主句为第一人称时，它的否定形式与think的用法相同，“否定在主句，翻译在从句”

Eg: I don’t believe he knows that place. 我认为他不知道那个地方。

5、Wu Ming went to Singapore / Hong Kong / Macao for his vacation.(P10)

go to ….for a / one’s vacation“去…度假”，for表示为了，vacation通常指一次性休假，英式英语常用holiday.

Eg: He went to Beijing for his vacation. Her parents are on vacation in Hawaii.

go on vacation“在度假”说明度假正在进行

Eg: I am going on a vacation in Beijing.

6、I’m going to Chiang Mai in two weeks.(P10)

in two weeks“两周后”，结构为“in + 一段时间”，表示“在….之后”，常用语一般将来时，对起提问用how soon

Eg: I will finish the work in two hours.

in以现在为起点，表示将来一段时间以后，常用语将来时态的句子中。

Eg: She will be back in three weeks.

after以过去为起点，表示过去一段时间以后，常用语过去时态的句子中，在某个特定的时
