    When a friend is sad about a tragedy (悲剧), it's hard to know how to comfort (安慰) him/ her. But the

worst thing you can do is say nothing. It could mean that you don't care. You don't have to say much. A

single supportive phrase doesn't require absolutely perfect words to break the ice. Here are some conversation

starters when difficult situations have your tongue tied.

1. A friend loses his baby. 

    Don't say:"Don't worry. You're so young. You'll have another baby." Do say:" I'm so sorry. I can't begin

to imagine what you are going through, but if you want to talk about it, call me anytime."

2. A guy deserts your friend.

    Don't say:"I never liked that rat bastard (坏蛋) anyway!" ( If the couple winds up reconciling (和解), you

could end up losing your friend.) Do say:"Breaking up is always hard to deal with, but I'm here for you,

whatever you need."

3. A friend has a death in the family.

    Don't say:"It's God's will." or "I know exactly how you feel." Do say:"I'm sorry about your loss. What can

I do to help?"

4. A friend loses a job suddenly.

    Don't say:" Work is always boring. Those employers didn't suit you!" Do say:" I'm sorry for that, but I

know there's an even better job waiting for you there. Let's think about possibilities."

5. Someone's pet dies.

    Don't say:"Gee! It was only a cat!" or "My roommate doesn't like her dog and she is getting rid of her dog.

Do you want it?" Do say:"I'm sorry, she was such a great cat. How long did you have it?"

1. Which of the following has the same meaning as the underlined part "have your tongue tied"?[ ]

A. make your tongue shut

B. tie your tongue in order not to say.

C. have no suitable words to say.

D. say what you want freely.

2. As a whole, what's the best way to comfort your friend troubled with a tragedy? [ ]

A. To show your sorrow and offer your help.

B. To try to make the tragedy less serious.

C. To tell your friend not to think about it any more.

D. To do your best to make him/her cheerful again.

3. Though your friend is deserted, you'd better not say dirty words about her/ his friend because _____. [ ]

据《星期日商报》报道,2月4日,英国航空航天部在对包括通讯卫星在内的一切通讯情报设施进行检测中,忽然发现军用卫星“天网”系统的一颗卫星不是拒绝接受信号,就是反应迟钝。当天,英国航空航天部组织专家研讨,就在这时,忽然来了一封电子邮件,声称他们劫持了“天网”卫星!

电子邮件称,一个黑客团体已经控制了“天网”卫星。他们是一群由电脑专家、密码专家和航空航天专家组成的团体。他们并不想搞破坏活动,由于经费不足,目前急需资助。他们成功地窃取了一颗“天网”卫星的资料,并对它进行遥控,切除了它和航天部的联系,改变卫星飞行的轨道。英国政府如果要收回卫星的控制权,必须交出赎金。否则他们就要把这颗卫星变成废铁。

由于英官方并没有公开澄清此事,所以一时间小道消息满天飞。虽然有人强调“天网”系统是封闭的系统,不可能由Internet入侵,但事实上,控制卫星的微波是开放的,截获卫星信号,夺取卫星控制权并非天方夜谭。一套信号发射系统只需要两只手提箱就可以装下,它们可以在任何地点被组装起来。而不间断地截获卫星信号,许多大学里的卫星天线就可以做到。所以单从技术上讲,“俘虏”卫星并非不可能。

“信息战争”一直被认为是一个“预言”,人们都相信它的可能性,但没有人知道它来得究竟有多快。据报道,1990年海湾战争中,美军曾经利用藏在打印机里的病毒破坏伊拉克的防空系统。俄罗斯卫星专家伊万诺夫•塔里夫说:现在争论“劫持卫星”事件的真实性已经没有意义,这条消息可以提醒各国政府,黑客已经开始对军事设施展开攻击。

能“劫持”别国卫星,最主要的依据是()。

A.因为控制卫星的微波是开放的

B.一套卫星发射系统只需两只手提箱就可以装下,且便于组装

C.许多大学的卫星天线就可截取卫星信号

D.单从技术上讲,“俘虏”卫星并非不可能
