【題目】今年4月，雅安地震給人們帶來巨大的災難．下列有關地震的說法正確的是（　�。�

A. 地震時由于板塊的碰撞或張裂引起的

B. 地震只能造成房屋倒塌、人員傷亡

C. 地震發(fā)生時，應迅速到房屋內(nèi)躲避

D. 我國已經(jīng)能夠準確預報地震

【答案】A

【解析】

地質(zhì)學家經(jīng)過長期研究，又提出了板塊構造學說。板塊構造學說認為，地球巖石圈是由板塊拼合而成的。全球主要有六大板塊，其中太平洋板塊幾乎全部是海洋，其余板塊既包括大陸，又包括海洋。海洋與陸地的相對位置是不斷變化的。

一般來說，板塊的內(nèi)部比較穩(wěn)定，板塊與板塊交界的地帶，有的張裂拉伸，有的碰撞擠壓，地殼比較活躍。雅安地震是由印度洋板塊與亞歐板塊碰撞或張裂引起的，地震會造成房屋倒塌、人員傷亡，且能夠在很短的時間內(nèi)改變地表的形態(tài)�，F(xiàn)在人類還不能夠準確預報地震，當?shù)卣鸢l(fā)生時，不要驚慌，要就近躲在課桌下面，并用書包護住頭部，千萬不要恐懼，更不能從窗戶跳下。趕快跑到開闊的地方，遠離建筑物。地震中不應乘車逃命，遠離交通工具。發(fā)生地震時應遠離建筑物、危險品，就近采取防護措施，更不能躲進防空洞。故選A。

【題目】How to become successful? This is an important question most young people often think about. When I was young, I also thought about this question quite often

Firstly, I think the most important quality(品質(zhì) )that a successful person should develop is the ability to think independently. There are a lot of chances, but not many people can realize that there are chances for them to make good use of. So you should have the ability to think independently. You should be able to understand what you can do best. What is the most suitable job for you? When you choose your job, you need to keep this in mind. Maybe you are good at sales; maybe you are good at technology; maybe you are good at starting a new company; maybe you are good at working for a large company. You need to think deeply to find out what you are good at. I think that is the most important thing. Secondly, once you have figured out what you want to do and what you can do best, you should focus on it. Do not change your job every year. It is not a good thing to change your job very often. Do not change your focus, either. You should know that if you focus on something, you may be able to do it better than most other people.
