Lesson 5 Dialogue

1. show的用法

①to offer for seeing (拿給人看) Show sth (to sb)或 show .

He showed his ticket at the door. 在門口的時候他拿出了他的票。

The doctor said,"Can you show me your tongue? 醫生說:"能讓我看一下你的舌頭嗎?"

② to go with and guide or direct. (引導、帶領)

May I show you to your seat? 可以讓我帶你到你的座位嗎?

Show the gentleman in. 把那位先生領進來。

③ make known or clear. 表明,說明。

The results show that you are right. 結果證明你是對的。

The introduction shows you how to use this machine. 介紹教給你怎樣使用這臺機器。

2. Have been 和have gone

①Have you been in this lab before?

②My father has goon to Shanghai on business.

③- " Where is Lily? "

--" She has gone to the library."

--" Do you know where it is? "

--Sure, I have been there many times. I will show you the way.

--Thank you.

注:have been to/in 強調過去式或去過多少次,着重指到目前的一個結果。

Have gone to 講的是現在的情況,着重指現在人不在,只用於第三人稱。

3、Before和ago

①I have never seen such a good film before. 我以前從未看過這麼好的電影。

②He finished this job not long before. 他不久前剛完成這項工作。

③注:before可以單獨使用,表"以前",也可以和ever, never, 或者示時間段連用,

如,ten years before,常與完成時連用。

We first met you two years ago 我們2年前第一次見到你

注:ago從不單獨使用,也不能與ever, never連用。但可與表示時間段的詞連用,表多長時間前,所以必須用過去時。

4、Once的用法

①Once you are (in) here, listen to your teacher's instructions.

一旦你來到這兒,就要聽從老師的要求。

②Once you Understand my words, you will believe me.

一旦你聽懂了我的話,你就會相信。

注:上面兩個例名中once是連詞,主句的動作是從句動作的條件,表"一旦"

①Take this medicine once a day. 這藥一天吃一次。

②Try it once more. 再試一次。

③Take it away at once! 馬上把拿來!

5. Unless的用法

Unless = if not 如果不…就…

①He told me that he wouldn'tt go to the party unless was invited.

他說如果不被邀請他就不去參加那個晚會。

②Stay home unless I phone.

除非我打電話,否則一直呆在家裏別出去。

6. Sure的用法

① I'm sure of his honesty.

sure that he is honest. 我相信他是誠實的。

注:be sure of + 名詞/that …

②He is sure to come. 他一定會來。

③make sure

I remember that there is a plane at 8:30 PM, but you'd better make sure.

我記得晚上8:30有一次航班,不過你最好去確定一下。

他什麼時候放學回家?

②MiLu Deer returned to china.

③Please return the book to the library on time.

老夫雪在倫敦度假。

16. While 並列邊詞,表句意轉折

① Mother is watching TV, while father is reading the newspapers.

17. 直接引語和間接引語

本單元的語法重點是直接引語和間接引語,本單元的checkpoint中例舉了四對例句,表明轉述祈使句時的變化,現作歸納講解。

① 如果直接引語是表示請求的口氣,則間接引語用 ask do sth.

如果直接引語是表示命令的口氣,則間接引語用 tell / order do sth.

② 否定式是not to do sth.

③ 注意人稱,時態做相應變化。

例: "Do not eat cold food " , the doctor said.

D "Do some shopping for me , please." ,he said to her.

→He asked her to do some shopping for him.

Y "You must do everything as I do" ,the professor said.

請將下列句子進行直接引語和間接引語的互換。

said to her, "Go away! "

er said to me, Come back before 10:00.

asked us to sit down.

told the boys not to make so much noise.

told us not to touch anything.

【答案】

1-5. A.A.C.C.A. 6-10. A.B.C.A.D.

ordered her to go away.

er told me to come back before 10:00.

said to as ,"please sit down."

said , "Don't make so much noise ,boys."

said, "Don't tough anything."

分析:1.本題考查祈使句轉爲間接引語的用法,完整的句子應爲 "His mother told him not to ride in the street." 爲了避免重複,省略了ride in the street.

2.本題考查詞義辨析。unless爲"除非,"unit (爲 …才,常用來表延續動作)

或狀態直到某時刻結束,如選①應爲Leave immediately, or you will be late.

on 爲"打開",turn off爲"關閉", turn up爲"把…調高.

turn down"把…調低"

rn是不及物動詞,返回某地要用return to.

ead of是介詞短語,表示"代替了…"實際上是"舍"。Instead是副詞,表示"取" 本句意思爲:格林先生病了,於是周小姐替他上課。

表示三者以上的否定,兩者的否定用neither,常回答以How many或How much

7.開頭的疑問句,既可表示人也可表示物。

no one一般指人,回答以who開頭的疑問句。

gh後常接for或不定式,表示結果,此句爲"對我來說夠好了。"另外還有:You

are kind enough to help us.肯幫助我們,你真好。

about? …怎麼樣? 因爲about是介詞,所以後面要跟動名詞或句詞。

the side of 指兩邊或這邊與那邊相對,by the side of 表示在…旁邊,

at the side of 意爲在…的邊上。
