覆盖层残酷的意思A
Temperature is measured by means of a thermometer (温度计). One general form of thermometer depends upon the fact that most solids and liquids expand as their temperature ris. There are one or two exceptions. There is, for instance, a kind of steel called invar (from “invariable”) which does not change its dimensions as temperature changes; it is valuable for making pendulums (钟摆), since, if the length of a pendulum changes, its time of vibration changes. It is also ud for making very accurate measuring scales. In both cas, then, changes of atmospheric temperature have no effect if invar is ud.
Another exception is that very odd liquid, water, which has many strange properties (特性). As water gets colder it contracts (收缩), which is ordinary behavior, until it reaches the temperature of 30℃. above freezing point. After that, as it gets colder, it expands. This is fortunate---for considering the freezing of a pond. As the water on top gets colder, it shrinks;
and so, volume for volume, it becomes heavier and sinks. This goes on until all the pond is at 30℃, but after that, as the water becomes colder it expands. Therefore the colder water stays on top and freezes, covering the pond with ice. If the water went on contracting down to the freezing point, the pond would become a solid block of ice in the end. This would not worry people who live in hot climates, but it would be very rious for tho who live in cold climates, especially for tho who want to break the ice and catch fish which live in the cold water beneath.

A. it can hardly change its shape or size as temperature changes.
B. it will change its dimensions without the change of temperature.
C. its time of vibration doesn’t change if its length changes.
D. its time of vibration does change if its length changes.
2. As water gets colder after reaching the temperature of 30℃. it will _______.
A. contract B. shrink C. expand D. freeze
3. Which of the following statements is true, according to this passage?
A. Only invar can be ud to make a thermometer.
B. Only water can be ud to make a thermometer.
C. Both invar and water can be ud to make a thermometer.
D. Neither invar nor water can be ud to make a thermometer.
4. The best title of this passage is most likely to be _____.
A. Temperature Measurement B. Two Exceptions
C. Us of Invar D. Properties of Water

The United States has always been a country of many cultures. Before Europeans came to North America, many groups of Native Americans lived here. Different Native American groups had different cultures. The first Europeans in the United States were from England and Holland, but immigrants came from all European countries.

Today, the United States has people from more cultures than ever.
In the 19th century, people spoke of the United States as a “melting pot.” People thought that all immigrates should forget their native cultures and languages and become English-speaking Americans. They felt that people should assimilate - join American culture. However, not everyone wanted to assimilate completely. Many people tried to keep parts of their cultures, such as foods, customs, and languages. However, their children often forgot their parents’ or grandparents’ language. But most Americans, even tho who families have been here a long time, can tell the countries their relatives came from. And of cour, new immigrants 深圳翻译公司take great pride in their curare and language.
