问题 填空题

2008年初,一场罕见的雪灾波及我国南方十六省区,造成巨大的经挤损失. (1)雪灾造成大量电线、电杆被积冰压断倒塌,其“元凶”主要是冻雨.冻雨是一种过冷水滴,当雨滴与地面、建筑物等物体相碰时会立即      (填物态变化名称)成冰,这一过程要     热量(填“吸收”或“放出”). (2)路面上的冰雪常会出现“夜冻昼化”的现象,给交通安全带来很大的隐患,为此护路工人常在路面上撒大量的盐,以避免 “夜冻昼化”现象的形成,因为冰雪熔化和盐溶解后形成的混合液体的凝固点将     (填“高于”、“低于”或“等于”)0℃.

答案

(1)凝固 放出 (2)低于

从题中看雪灾是电线、电杆被积冰压断倒塌,积冰是冻雨形成的,可见这是凝固现象,是放热的.

在路面上撒大量的盐,避免了“夜冻昼化”现象,也就是说冰雪熔化和盐溶解后形成的混合液体在夜间不会再凝固,可见是凝固点在0℃以下.夜间的温度降不到这种混合液体的凝固点,故不凝固.

Certain people make you feel comfortable when they are around. You spend an hour with them and feel as if you’ve known them half your life. These people have something in common. And once you know what it is, we can try to do it ourselves.

How is it done? Here are several skills that good talkers have. If you follow the skills, they will help you to put people at their ease, and make friends with them quickly.

First of all, good talkers have asked questions. Almost anyone, no matter how shy he is, will answer a question. One well-known businesswoman says, “At business lunches, I always ask people what they did that morning. It’s a common question, but it will get things going.” From there you can move on to other matters ----sometimes to really personal questions. And how he answers will let you know how far you can go.

Second, once good talkers have asked questions, they listen for the answers. This point seems clear, but it isn’t. Your question should have a point and help to tell what sort of person you are talking to. And to find out, you really have to listen carefully and attentively.

Real listening at least means some things. First it means not to change the subject of conversation. If someone sticks to one topic, you can take it as a fact that he is really interested in it. Real listening also means not just listening to words, but to the tone (语调)of voice. If the voice sounds dull, then it’s time for you to change the subject.

Finally, good talkers know well how to deal with the occasion of parting. If you’re saying goodbye, you may give him a firm shakehand and say, “I’ve really enjoyed meeting you.” If you want to see that person again, don’t keep it a secret. Let people know what you feel, and they may walk away feeling as if they’ve known you half their lives.
