Even if trees cannot walk, they are still on the move.
In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra (冻原) starts has been shifting northward. Trees growing along the tree line must protect themselves from the cold wind. To do this,_plants tend to grow horizontal (水平的) branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.
But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all that leftover energy, these trees have started producing more seeds. This happens especially in places where white spruce (白云杉) grows.
White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When windblown seeds end up on the tundra beyond the tree line, they eventually can sprout(发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.
New trees will provide shelters for some snow. Keeping the sun's rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below, which encourages trees to grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about impacts on the animals that depend on frozen conditions for food and shelter.
1.What is the main cause of the trees in the Arctic moving northward?
A．The shrinking of northern tundra.
B．The rising temperature.
C．The fierce and cold wind.
D．The abundant resources in the north.
2.What does the underlined word “this” in Paragraph 2 mean?
A．To produce more seeds.
B．To move northward.
C．To respond to the climate change.
D．To protect themselves from the cold wind.
3.What can be inferred from the last paragraph?
A．New trees can trap the snow, which may make the soil colder.
B．The trapped snow prevents new trees from producing more seeds.
C．New trees can make the surrounding air warmer.
D．New trees can bring more food and shelter to local animals.
4.The passage is most probably taken from ________.
A．a science report B．a health report
C．a fashion magazine D．a children's magazine

Certain aspects of music have the same effect on people even when they live in very different societies, a new study reveals.
Researchers asked 40 Mbenzele Pygmies in the Congolese rainforest to listen to short clips of music. They were asked to listen to their own music and to unfamiliar Western music.
The same 19 selections of music were also played to 40 amateur or professional musicians in Montreal. Musicians were included in the Montreal group because Mbenzele Pygmies could be considered musicians as they all sing regularly for ceremonial purposes, the study authors explained.
Both groups were asked to rate how the music made them feel using emoticons, such as happy, sad or excited faces.
There were significant differences between the two groups as to whether a specific piece of music made them feel good or bad. However, both groups had similar responses to how exciting or calming they found the different types of music.
"Our major discovery is that listeners from very different groups both responded to how exciting or calming they felt the music to be in similar ways," Hauke Egermann, of the Technical University of Berlin, said in a news release from McGill University in Montreal. Egermann conducted part of the study as a postdoctoral fellow at McGill.
The Montreal participants felt a wider range of emotions as they listened to the Western music than the Pygmies expressed when listening to either their own or Western music. This may be due to the different roles music plays in the two cultures.
"Negative emotions are felt to disturb the harmony of the forest in Pygmy culture and are therefore dangerous," Nathalie Fernando, of the University of Montreal's faculty of music, said in the news release. "If a baby is crying, the Mbenzele will sing a happy song. If the men are scared of going hunting, they will sing a happy song — in general, music is used in this culture to evacuate all negative emotions, so it is not really surprising that the Mbenzele feel that all the music they hear makes them feel good," she explained.
1.Why could Mbenzele Pygmies be regarded as musicians?
A. They are crazy about music.
B. They major in music at school.
C. They can play musical instruments well.
D. They often sing songs on ceremony.
2.The study mainly finds that ________.
A. music is universal across cultures
B. music varies among different countries
C. western music results in negative emotions
D. music makes people happy
3.The underlined word “evacuate” probably means ________.
A. set off B. benefit from C. get rid of D. account for
4.The examples mentioned in the last paragraph are to show that ________.
A. music plays different roles in the two cultures
B. music plays the same role in the two cultures
C. negative music disturbs the harmony of the forest
D. happy music is welcomed everywhere

Whenever human populations have lived in forest areas, they have always cut down trees which they used for a number of purposes, for housing and ships and served as a source of heating fuel and timber. Growth of cities often meant expansion into forest areas, while even more trees were removed to provide space for agriculture. With the growing demand for paper, vast quantities of trees have also been cut down for paper production. These factors, along with many others, have been contributing to a dangerous phenomenon known as deforestation.
In the last 5,000 years, humans have reduced forest from roughly 50 percent of the earth’s land surface to less than 20 percent. Most of this original, or old growth, forest cover is concentrated in three large areas: the Canadian and Alaskan boreal forest, the boreal forest of Russia, and the tropical forest of the northwestern Amazon Basin and the Guyana Shield. These areas comprise almost 70 percent of the world’s remaining original forest cover. In most places, the rate of deforestation is increasing, with the alarming result of 16 million hectares disappearing worldwide every year.
Loss of forest does not just mean the decline of natural resources. There are several other factors that make deforestation seriously harmful to both the human and natural worlds. One of them is changes in the global climate. For example, forest clearance is releasing substantial volumes of carbon dioxide (CO2) into the atmosphere as vegetation is burnt or decays. It has been suggested that this is a significant factor in global warming. Moreover, about 10 percent of the world’s tree species are in danger of extinction as a result of deforestation. Deforestation also threatens biological diversity through the destruction of wildlife habitats, which endangers a number of animal species and leads to their potential disappearance. Species are particularly easy to extinction in tropical rainforests because many species have few individuals per unit area, which makes reproduction more difficult. Finally, since forests play an important role in storing water and stabilizing soil, deforestation and the resulting change in land use cause soil erosion (腐蚀) and other forms of land degradation.
1.The passage discusses all of the following EXCEPT the ________.
A. causes of deforestation B. consequences of deforestation
C. management of deforestation D. rate of deforestation
2. The word “diversity” in the last paragraph probably means “________”.
A. variety B. expansion
C. development D. advantage
3.Why does the author mention fuel and timber in Paragraph 1?
A. To explain the rate of deforestation.
B. To compare them with housing and ships.
C. To show the dangers of deforestation.
D. To illustrate the causes of deforestation.
4.Which of the following sentences summarizes Paragraph 3 best?
A. Deforestation threatens biological diversity.
B. Deforestation has many harmful consequences.
C. Deforestation causes changes in global climate.
D. Deforestation should be stopped.

Many different tribes live in the Ituri rain forest of Africa, but the Pygmies are the most unusual．Most of the men are not much more than four feet tall．They weigh only about eighty pounds．The women are even smaller and thinner．But in spite of the fact that they are small, these people are perfectly formed men and women．
It is an exciting experience to visit a Pygmy encampment for the first time．Before you go, you must send word ahead that you are coming．Some friendly native or trader must take the message to the Tiki-Tikis．Otherwise the whole tribe will disappear into the depths of the jungle long before you have come close enough to be welcomed．
The great Ituri rain forest seems cut off from the rest of the earth．There are living, dead, and dying trees on every side．Except where a clearing has been burned and chopped out, a man may live his whole life in the Ituri and never see farther than twenty yards．
It takes sharp eyes to discover the almost hidden path to the Pygmy camp．The path is no wider than a small man’s foot．No sound breaks the silence in this part of the forest．There are no signs of people．
The stranger must walk carefully．What appears to be a bent branch may prove to be a deadly snake．A spotted gold patch of sunlight may be a crouching leopard（豹）．
Even the Pygmy camp comes as a surprise．The leafy shelters in which the little people live are hardly three feet high．They look so much like the surrounding undergrowth that they might easily be passed by．These houses contain no furniture of any sort．The beds are merely plantain leaves spread out on the earth floor．There are no cooking pots: food is eaten raw or smoked over a fire．Spears, bows and arrows are the only possessions of these people．When the tribe moves to a new camp there is nothing to carry except these weapons and babies too small to walk．
