Where do you keep ice? In the freezer, of course. That’s what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers from around the world. They’ve decided to store ice in Antarctica because global warming is causing some of the glaciers in places like the Alps to melt.
Jerome Chappellaz of the French National Centre for Scientific Research is involved in creating an ice vault (地下室) there. He says: “We are probably the only scientific community whose sample (样本) is in danger of disappearing from the face of the planet. If you work on rocks or on tree rings, the raw material is still here and will be for many centuries.”
And why do scientists need to study ice from the Alps, for example? Ice formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles (气泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate. By examining ice, we know carbon dioxide in the atmosphere is higher now than in the last three million years. Researchers use this kind of data to build computer models and try to predict what might happen in the future.
The ice vault will be housed in a snow cave at the Concordia Research Station, which is operated by scientists from France and Italy. The ice samples will be sealed in bags and placed 10 meters below the surface, at a constant temperature of -50℃. This will put the scientists’ minds at rest. Losing the ice samples would be a disaster, and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.

日常生活类阅读的概念:
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作,生活以及学习情况。做这一类题时,最主要的是要把握好人物的活动内容,时间和地点。
日常生活类阅读题答题技巧:
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小,追根溯源,探索各项风俗的历史渊源,内容有趣。命题也以送分题为主,如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松,试题做起来比较顺手,但绝不能掉以轻心。因为稍不留神,就会丢分。
【备考提醒】
为了保证较高准确率,建议同学们做好以下几点:
1、保持正常的考试心态。笔者在教学中发现,越是容易的试题,同学们越是容易失分。为什么呢?因为在这种情况下,同学们极易产生麻痹思想,认为题目好做,就不引起高度重视,于是思维不发散、不周密。而命题人就是利用同学们的这一弱点,设计陷阱题。所以,无论试题难易与否,我们都要保持正常的考试心态。试题容易,不欣喜;试题难,不悲观。
2、根据前面讲到的方法,认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义,确定多义词或短语在文中的意思,确认文中的某个代词所指代的对象,或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子,切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提,以具体事实为依据进行推理,做出判断。这种推理方式比较直接,只要弄清事实,即可结合常识推断出合理的结论。

Nowadays more and more foreign enterprises and companies are no longer relying on interviews for recruitment. Years of studying interviewing has made clear that it is not a very objective process. Personnel officers often hire the person they like best or even the one they think most physically attractive. Looking good is no guarantee of doing the job well.

To get a more objective view, many companies are also using psychological tests, to hire both for relatively routine job and for positions at senior levels of management. It is impossible to say how many employers use tests, but estimates of test sales in the

Recruitment can involve steps in two ways. Step 1 is always the same: job application. The company decides whether you might be suitable based on your qualifications and your previous job experience. Step 2 can be screening. A specific test is given at this stage to rule out those who might not be worth interviewing. Some large employers use tests ---especially IQ based tests precisely to eliminate the unsuitable. Only those who pass Step 2 go to the interview. Step 2 can also be testing and interview combined. If the company thinks you might be suitable after looking at your application, they ask you to come to be tested and to be interviewed. It is seen very much as part of the same step.

Tests claim to be scientific and objective. A large body of research has shown that interviews by themselves are not very reliable as a method of selection. People’s judgments are often very subjective: whether they like the look of someone counts for more than almost anything else. But reliable and valid tests can offer rapid and more objective information about would-be employees. If a candidate talks well in an interview but his test results suggest that he is a careless person who cannot concentrate, and employer is likely to think twice about hiring him.

Taking a serious test for a job is rather different form taking a game-like test. You can spend just a little time answering questions of that kind of test, and you can deny the answers and say they are not accurate. But you can not go to a serious test without enough preparation since you can not afford to be denied and eliminated again and again. What can you do to do justice to yourself in tests? Here are three tips: Understand, Analyze, Practice.
