The doctor said,"Can you show me your tongue? 醫(yī)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)

③ make known or clear. 表明，說明。

2. Have been 和have gone
①Have you been in this lab before?

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(diào)過去式或去過多少次，著重指到目前的一個結(jié)果。
Have gone to 講的是現(xiàn)在的情況，著重指現(xiàn)在人不在，只用于第三人稱。
3、Before和ago
①I have never seen such a good film before. 我以前從未看過這么好的電影。
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。

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.

②Stay home unless I phone.
除非我打電話，否則一直呆在家里別出去。
6. Sure的用法

他什么時候放學回家？
②MiLu Deer returned to china.

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(zhuǎn)述祈使句時的變化，現(xiàn)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 sb.to do sth.
如果直接引語是表示命令的口氣，則間接引語用 tell / order sb.to do sth.
② 否定式是not to do sth.
③ 注意人稱，時態(tài)做相應變化。
例： "Do not eat cold food " , the doctor said.
→the doctor told the patient not to eat cold food.
D "Do some shopping for me , please." ,he said to her.

3.She said to as ,"please sit down."
4.He said , "Don't make so much noise ,boys."
5.She said, "Don't tough anything."
分析：1.本題考查祈使句轉(zhuǎn)為間接引語的用法，完整的句子應為 "His mother told him not to ride in the street." 為了避免重復，省略了ride in the street.
2.本題考查詞義辨析。unless為"除非，"unit (為 …才，常用來表延續(xù)動作)
或狀態(tài)直到某時刻結(jié)束，如選①應為Leave immediately, or you will be late.
3.turn on 為"打開"，turn off為"關閉"， turn up為"把…調(diào)高.
turn down"把…調(diào)低"
4.return是不及物動詞,返回某地要用return to.
5.instead of是介詞短語，表示"代替了…"實際上是"舍"。Instead是副詞，表示"取" 本句意思為：格林先生病了，于是周小姐替他上課。
6.none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。
8.enough后常接for或不定式，表示結(jié)果，此句為"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。
9.what about? …怎么樣？ 因為about是介詞，所以后面要跟動名詞或句詞。
10.on 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 意為在…的邊上。
