Lesson 5 Dialogue
1. show的用法
①to offer for seeing (拿给人看) Show sth (to sb)或 show sb.sth.
He showed his ticket at the door. 在门口的时候他拿出了他的票。
The doctor said,"Can you show me your tongue? 医生说："能让我看一下你的舌头吗？"

Show the gentleman in. 把那位先生领进来。
③ make known or clear. 表明，说明。

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 强调过去式或去过多少次，着重指到目前的一个结果。

3、Before和ago
①I have never seen such a good film before. 我以前从未看过这么好的电影。
②He finished this job not long before. 他不久前刚完成这项工作。
③注：before可以单独使用，表"以前"，也可以和ever, never, 或者示时间段连用，
如，ten years before,常与完成时连用。
We first met you two years ago 我们2年前第一次见到你
注：ago从不单独使用，也不能与ever, never连用。但可与表示时间段的词连用，表多长时间前，所以必须用过去时。
4、Once的用法
①Once you are (in) here, listen to your teacher's instructions.
一旦你来到这儿，就要听从老师的要求。

一旦你听懂了我的话，你就会相信。

②Try it once more. 再试一次。
③Take it away at once! 马上把拿来！
5. Unless的用法
Unless = if not 如果不…就…
①He told me that he wouldn't go to the party unless was invited.

②Stay home unless I phone.
除非我打电话，否则一直呆在家里别出去。
6. Sure的用法

【答案】
1-5. A.A.C.C.A. 6-10. A.B.C.A.D.
1.He ordered her to go away.
2.Mother told me to come back before 10:00.
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.本题考查祈使句转为间接引语的用法，完整的句子应为 "His mother told him not to ride in the street." 为了避免重复，省略了ride in the street.
2.本题考查词义辨析。unless为"除非，"unit (为 …才，常用来表延续动作)
或状态直到某时刻结束，如选①应为Leave immediately, or you will be late.
3.turn on 为"打开"，turn off为"关闭"， turn up为"把…调高.
turn down"把…调低"
4.return是不及物动词,返回某地要用return to.
5.instead of是介词短语，表示"代替了…"实际上是"舍"。Instead是副词，表示"取" 本句意思为：格林先生病了，于是周小姐替他上课。
6.none表示三者以上的否定，两者的否定用neither,常回答以How many或How much
7.开头的疑问句，既可表示人也可表示物。
no one一般指人，回答以who开头的疑问句。
8.enough后常接for或不定式，表示结果，此句为"对我来说够好了。"另外还有：You
are kind enough to help us.肯帮助我们，你真好。
9.what about? …怎么样？ 因为about是介词，所以后面要跟动名词或句词。
10.on the side of 指两边或这边与那边相对，by the side of 表示在…旁边，
at the side of 意为在…的边上。
