Body language is of great importance tohumans. We carry many of the meanings through bodymovements. However, many forms of body language we consider to be fine in our country can get usinto trouble in other parts of the world.
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' tnecessarily an expression of joy but it can be used to express pain.
The acceptable physical distance is another major difference. In Latin America and the MiddleEast the acceptable distance is much shorter than what most Europeans and Americans feet comforta-ble with. Hand and arm movements as a form. of body language are also very different amongcountries. Handshakes are usually acceptable almost everywhere, even between strangers;however,kissing on the cheek and touching on the shoulder or other body parts aren' t. For many people inAsia and other parts of the world, such actions are seen as a violation (侵犯) of one' s personalspace. This is why you should not touch others easily.
Eye contact(目光接触)is one of the forms of body language where the differences are most strikingInAmerica and Latin America looking the other person in the eye is a sign of respect. But in Asian countries,prolonged(过长的)eye contact is especially rude,so you should try your best not to do that.

No one knows for sure why birds migrate．One theory of migration says that ancient birds of the northern part of the earth were forced southward during the Ice Age，when ice covered large parts of Europe，Asia and North America．As the ice melted，the birds came back to their homelands，spent the summer，and then went south again in winter．Gradually，these comings and goings became habits，and birds now migrate though much of the ice has gone． Another theory proposes that the ancient home of all modern birds was the tropic areas．There lived so well that the region became overcrowded．Many species had to move northward．During the summer，these birds found plenty of room and food．In winter，however，food be-came scarce and they had to return to the south． A newer theory is that increasing daylight stimulates certain glands（腺）in the bird’s body and prepares it for migration．One scientist is able to make birds migrate in midwinter by expo-sing them for two months to artificial daylight．Recoveries of marked birds indicate that they fly north as soon as they are set free．The conclusion is that the urge to migrate is determined by changes in the bird’s body which take place under seasonal changes in the length of daylight． This theory would account for the fact that not all birds migrate at the same time．Each sDecies seems to have its own schedule．The theory would also account for the regular time and rou‘tes of migration．Birds arrive at a given place year after year．Unfavorable weather delays them only a few days．Total hours of daylight，rather than weather，start them on the way． How birds find their way to the same place year after year and why they follow their own Darticular route are still mysteries．They evidently do not follow known landmarks，for many young birds migrate alone without the help of experienced adults．
We can conclude from the first paragraph that__________ ．
A.during the Ice Age，the whole Europe was covered with ice
B.the south used to be the homelands of all birds
C.scientists can confidently explain why birds migrate now
D.migration of birds can be explained by the change of ice on earth

B.Birds usually follow regular routes of migration．
C.Each species has a special reason for migration．
D.Birds migrate to their own particular places every year．
Rivers are one of our most important natural resources (资源). Many of the world's great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
The greatest river for navigation is ___________.
From a dam, people can use the water for ___________.
A.keeping the rivers clean
B.only making electricity
D.irrigation and making electricity
