A smile is one of the most common examples in different countries. While Americans smile freely atstrangers,in Russia this is considered strange and even impolite. In Asian countries a smile isn&39; tnecessarily an expression of joy but it can be used to express pain.

第3题
Students of human migration speak of "push" and "pull" factors, which influence an individual's decision to move from one place to another. Push factors are associated with the place of origin. A push factor can be as simple and mild a matter as difficulty in finding a suitable job, or as traumatic as war, or severe famine. Obviously, refugees who leave their homes with guns pointed at their heads are motivated almost entirely by push factors (although pull factors do influence their choice of destination).
Pull factors are those associated with the place of destination. Most often these are economic, such as better job opportunities or the availability of good land to farm. In general, pull factors add up to an apparently better chance for a good life and material well-being than is offered by the place of origin. When there is a choice between several attractive potential destinations, the deciding factor might be a non-economic consideration such as the presence of relatives, friends, or at least fellow countrymen already established in the new place who are willing to help the newcomers settle in.
Besides push and pull factors, there are what the sociologists call "intervening obstacles." Even if push and (or) pull factors are very strong they still may be outweighed by intervening obstacles, such as the distance of the move, the trouble and cost of moving, the difficulty of entering the new country, and the problems likely to be encountered on arrival. The decision to move is also influenced by "personal factors" of the potential migrant. The prospect of packing up everything and moving to a new and perhaps very strange environment may appear interesting and challenging to an unmarried young man and appallingly difficult to a slightly older man with a wife and small kids. Similarly, the need to learn a new language and customs may excite one person and frighten another. Regardless of why people move, migration of large numbers of people causes conflict. The United States and other western countries have experienced adjustment problems with each new wave of immigrants. It has usually taken several decades for each group to be accepted into the mainstream of society in the host country.
Today it is found that movement between nations often exceed international movements in volume.
A．True
B．False

As you know, the turning of the earth makes the sun and the stars seem to move across the sky. Daylight, of course,【21】, when the sun rises in the east and when the sun is high【22】the sky, between these two positions, half of the daylight hours have been spent.
Therefore, by noticing【23】the sun stood in the sky, early man know they could tell the time of the day, At night the motion of the stars【24】the same purpose. The important thing in keeping time is to know the exact moment of【25】. For each of us, wherever we are, noon is when the sun is directly overhead. Think of an imaginary line【26】the sky, stretching from the north point of your horizon just to the south point.
When the sun cross your meridian (子午线), it is noon for you. When the sun still【27】of this line, or the meridian, it is morning. After the sun has crossed this line, it is【28】.
The Latin word for "midday" is "deridian",【29】which comes our word meridian. So AM is an abbreviation (缩写词) for "ante meridean", or before midday, and PM for after midday. Each or the world's time zones (时区) is about fifteen degrees wide in longitude (经度), which is about the distance the sun moves through tile sky in all hour.【30】lives in the same time zone observes noon at the same moment. In this way, the time is different by one hour as you move through each time zone.

People who are near-sighted can only see things that are very close to their eyes.' Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them."
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
We should take good care of our eyes ______.
A．only when we cannot see perfectly
B．only when we can see well
C．even if we can see well
D．only when we realize how important our eyes are

When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
