2014 高考英语阅读理解基础训练二轮精品题（15）及答案<br />A<br />Temperature is measured by means of a thermometer (温度计). One general form <br />of thermometer depends upon the fact that most solids and liquids expand as their <br />temperature rises. There are one or two exceptions. There is, for instance, a kind <br />of steel called invar (from &ldquo;invariable&rdquo;) which does not change its dimensions <br />as temperature changes; it is valuable for making pendulums (钟摆), since, if the <br />length of a pendulum changes, its time of vibration changes. It is also used for <br />making very accurate measuring scales. In both cases, then, changes of atmospheric <br />temperature have no effect if invar is used. <br />Another exception is that very odd liquid, water, which has many strange <br />properties (特性). As water gets colder it contracts (收缩), which is ordinary <br />behavior, until it reaches the temperature of 30℃. above freezing point. After that, <br />as it gets colder, it expands. This is fortunate---for considering the freezing of <br />a pond. As the water on top gets colder, it shrinks; and so, volume for volume, it <br />becomes heavier and sinks. This goes on until all the pond is at 30℃, but after <br />that, as the water becomes colder it expands. Therefore the colder water stays on <br />top and freezes, covering the pond with ice. If the water went on contracting down <br />to the freezing point, the pond would become a solid block of ice in the end. This <br />would not worry people who live in hot climates, but it would be very serious for <br />those who live in cold climates, especially for those who want to break the ice and <br />catch fish which live in the cold water beneath.<br />1. Invar is valuable for making pendulums because _______.<br />A. it can hardly change its shape or size as temperature changes. <br />B. it will change its dimensions without the change of temperature.<br />C. its time of vibration doesn’t change if its length changes. <br />D. its time of vibration does not change if its length changes.<br />2. As water gets colder after reaching the temperature of 30℃. it will _______.<br /> <br />A. contract B. shrink C. expand D. freeze<br />3. Which of the following statements is true, according to this passage?<br />A. Only invar can be used to make a thermometer. <br />B. Only water can be used to make a thermometer.<br />C. Both invar and water can be used to make a thermometer. <br />D. Neither invar nor water can be used to make a thermometer. <br />4. The best title of this passage is most likely to be _____.<br />A. Temperature Measurement B. Two Exceptions<br />C. Uses of Invar D.
