雅思阅读文章应该优先做哪篇?

雅思阅读考试主要有三篇文章，每篇文章所涉及到的背景知识，题型，难度等方面会有所不同。那么，考生就有所疑问了，到底雅思阅读文章先做哪一篇才能有效节省时间与提高效率呢?

在备考雅思阅读考试时，多数考生存在这样一个误区，即三篇文章的难易程度是递增的，因而在考试时，如果时间不够的话就不怎么管第三篇文章了，把前两篇文章做完并做对就已经不错了。其实，这是一种非常错误的观念。因为阅读文章的难易程度不是由易到难的，而是随机的。具体先做哪一篇，考生还是要理性地分析。

实际上，既然雅思阅读文章有题材考察与题型考察之分，那么考生其实就可以从这两个角度进行分析，看看自己究竟适合先做哪一篇。

从雅思阅读题材角度来看：

雅思阅读文章通常分为生物，地理和社会科学三大类，不同类别包含的内容繁多，考生要熟悉了解。比如生物类题材是常考题材之一，常常涉及到动物的生活习性，基因研究，器官研究等。地理类题材有一定难度，所涉及的专业知识较多，范围也很广泛，如气象预测，沙漠化之类的。社会类题材可以说是一个比较大的范畴，包含众多小的分支，如教育，历史，考古等等。

当考生拿过试卷后，要将三篇文章的主标题，副标题，插图以及第一句话全部浏览后，选择一篇从题材上自己比较熟悉和了解的文章先做，毕竟这样的文章背景知识和专有名词对于考生来说是相对熟悉的，做起题来就会容易一些。

从雅思阅读题型角度来看：

在雅思阅读考试中，如果考生对于三篇文章背景知识的掌握程度差不多的话，就可以在浏览完三篇文章所涉及到的所有题型之后，就可以选择一篇从题型上自己比较拿手的文章先做。

雅思阅读题型主要有八种，即list of headings，complete the sentences，answer short questions，picture filling，summary，multiple choices，matching，true or false or not given。不同题型的难易也会不同，比如list of headings也就是标题对应题，这类题型无需定位，但需要对文章大体的内容有一定理解，难度系数两颗星; matching因果配对无出题规律，定位也比较复杂，难度系数三颗星;true or false or not given定位相对简单，但是往往在判断时容易失误，难度系数两颗星。

总而言之，考生要根据自己对不同题材和题型的掌握程度来决定雅思阅读文章先做哪一篇，也就是要合理安排做题顺序，这样才会高效完成任务。另外，考生在打好基础之后在平时最好能够按照实际的阅读考试时间来做题，检测一下自己是否能够在规定时间内做完所有题目，并找出不足之处加以改进。希望考生们取得满意的雅思成绩。

雅思阅读模拟题及答案解析(1)Time to cool it

1.雅思阅读材料

1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.

2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down.

3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications.

4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers.

5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second.

6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking the processor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the end of the road in sight.

7 One way out of this may be a second curious physical phenomenon, the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.

8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path of phonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient than paraelectric ones (or, at least, than those examined by Dr Mischenko). Nevertheless, Rama Venkatasubramanian, of Nextreme Thermal Solutions in North Carolina, claims to have made thermoelectric refrigerators that can sit on the back of computer chips and cool hotspots by 10℃. Ali Shakouri, of the University of California, Santa Cruz, says his are even smaller--so small that they can go inside the chip.

9 The last word in computer cooling, though, may go to a system even less techy than a heat pump--a miniature version of a car radiator. Last year Apple launched a personal computer that is cooled by liquid that is pumped through little channels in the processor, and thence to a radiator, where it gives up its heat to the atmosphere. To improve on this, IBM's research laboratory in Zurich is experimenting with tiny jets that stir the liquid up and thus make sure all of it eventually touches the outside of the channel--the part where the heat exchange takes place. In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers. The old, as it were, hand in hand with the new.(830 words)
