口语练习对话：网络安全

　　有关“网络安全”的口语练习对话资料，后面还有讲解哦。

　　Repairman: What can I do?

　　Benjamin: The system crashed when I was surfing on the internet.

　　Repairman: Did you go to any illegal website?

　　Benjamin: No, But does that matter?

　　Repairman: Yes, your computer can be easily infected by virus if you do that.

　　Benjamin: I see. I'd better never try.

　　Repairman: That's wise.

　　Benjamin: Do you know what's wrong with my PC?

　　Repairman: One minute. Oh, yes, it was infected by a virus, and you had no antivirus software.

　　Benjamin: Is anti-virus software necessary for a PC?

　　Repairman: Of course. You'd better learn something about it.

　　Benjamin: I'm afraid yes. But what about the data I stored in the computer?

　　Repairman: Don't worry, it should have been protected automatically. And I take an anti-virus software with me. Do you want me to install it now?

　　Benjamin: Yes, please. I'll really appreciate that.

　　维修员：我需要做什么?

　　本杰明：我正在上网，电脑却突然去世机了。

　　维修员：你上过非法网站吗?

　　本杰明：不。那有关系吗?

　　维修员：是的，如果那么做你的电脑很容易受到病毒沾染。

　　本杰明：知道了。那最好不要尝试。

　　维修员：那是理智的。

　　本杰明：你晓得我的电脑怎么了吗?

　　维修员：等一下。哦，是的，它感染病毒了，你不装杀毒软件啊?

　　本杰明：对电脑，杀毒软件是必需的吗?

　　维修员：当然了。你最好对它多一些理解。

　　本杰明：恐怕是要这样。不过我原来存在电脑里的数据会怎么?

　　维修员：别担心。应该已经被自动保存了。我带了杀毒软件，您渴望我当初帮你安装吗?

　　本杰明：请装吧。很感谢你。

　　经典背诵 Recitation

　　Repairman: I repair computers everyday. Many people don't know the right way to use computers. Many of them wonder how to protect their computers from being infected by virus. Some of them keep on logging on the illegal websites where some virus may be lurking. I think people should learn something about the computer before using it.

　　在口语练习对话中的had better 的用法

　　had better (常简略为'd better)是固定词组，常表现“最好”，用于表示对别人的劝告、倡导或表示一种愿望，主语不论是第多少人称，句子不管是什么时态，都要用had better 的形式。其用法有以下多少点：

　　1.had better 后面必须跟动词原形

　　had better 后跟动词本相，即不带to 的不定式，构成had better do sth.句型，例如：

　　You'd better go to hospital at once. 你最好即时去医院看病。

　　2.had better 的否认式

　　常用的否定情势是将not 直接放在had better 的后面，例如：

　　You had better not do that stupid thing. 你最好不要做那样愚笨的事。

　　You had better not leave her alone. 你最好不理她。

　　3.在祈使句中，had 有时可能省略

　　Better not do it. 最好别做那事。

　　Better not wait for them. 最好不要等他们。
