In recent years, the black bear population in the US has risen. Forests once cleared for farming have started to grow back and black bears have returned to them. But the bears are finding that their forest habitat has changed. Instead of thick forests covering thousands of acres, bears now have neighbors nearby. Roads, homes, schools, and shopping centers have been built at the edge of their forest home. And with humans and bears trying to share the same space, problems arise.

Black bears usually prefer to avoid people, but their nose may lead them into trouble. Their normal diet includes nuts, insects, and plants. But given the opportunity, they will gladly help themselves to whatever they can find.

With the great sense of smell, the bears can sniff out a tasty treat 2 or 3 miles away. Food left out in a park or backyard is an invitation to dinner. And while raiding (劫掠) a cooler, bird feeder (喂鸟器), trash can, car, or even a home, they can do a lot of damage. When that happens, people get angry. If another solution doesn’t immediately appear, they often want the bears killed.

Bear Aware, Bear Wise, and Bear Smart are trying to keep that from happening. They want people to respect bears, not fear them, and are suggesting ways to reduce the chances of bears stopping by for a snack. They’re convincing (使相信) people that by following some simple steps, it’s possible to live peacefully with our wild neighbors.

1.More black bears have appeared in the US because__________.

A．farmers have grown more food

B．forests have increased in the US

C．people stopped killing black bears

D．roads were built nearer to the forests

2.We learn from the text that black bears _________.

A．hate insects in forests                    B．eat different foods

C．usually live in big groups                  D．like to share space with humans

3.The underlined words “sniff out” in Paragraph 3 probably means “________”.

A．to express a low opinion                  B．to find something by chance

C．to refuse something in a proud way          D．to discover something by its smell

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.

The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege （特权） to visit.” This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.

Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.

The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饥饿） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.

1.The destruction of the environment of the Kaibab resulted from

A．interfering with natural cycle of forest life

B．turning the forest into cultivated land

C．forest fires caused by man’s carelessness

D．cutting the trees for building materials

2."Engelmann spruce"（Para. 2） is most likely the name of .

A．an animal         B．a tree            C．a mountain        D．a game

3.The number of the deer in the Kaibab had increased enormously in     years’ time.

A．25               B．6                C．12               D．18

4.Years later, large numbers of deer in the Kaibab died mainly because of .

A．the cold                              B．the organized kill

C．the poor management                    D．the shortage of food

Some unwelcome visitors from North America have been turning up in the waters off the coast of Great Britain.

North American lobsters (龙虾) have been found in the North Sea (between Great Britain and Northwest Europe), far from their own habitat. The lobsters usually live along the eastern coast of Canada and the United States.

It is impossible that the lobsters could have made the 5,600-kilometre journey on their own. They were probably brought to Britain and then got away from containers. Some of the lobsters that were caught had elastic bands (松紧带) holding their legs shut, like lobsters that are kept in containers in stores or restaurants.

Many may have been “set free” from some ships passing through the area. Sometimes passengers order a live lobster from a tank in the dining room and then ask the waiter to throw it overboard instead of cooking it.

According to official records, 26 North American lobsters have been caught in waters off Great Britain since 1988. However, it is believed many more have been found but not reported.

It is against the law to let North American lobsters come into British waters. If they settle down in European waters, it would be bad for the local lobsters. The two live in the same place and eat the same food. But North American lobsters are larger, stronger and more aggressive (好斗的) than European lobsters, and they produce young more quickly.

As a result, they could take food and space away from the local lobsters, and from other types of shellfish that live in the same area. These lobsters may also carry diseases that could harm the local lobsters.

1.Those unwelcome lobsters _____.

A. could travel 5,600 km a day on their own

B. used to live in waters off Great Britain

C. would soon disappear in British waters

D. might have escaped on the way to Britain

2.What can we learn about European lobsters?

A. They are growing too fast to be kept under control.

B. Shellfish often take away their food and space.

C. They are easily harmed by North American lobsters.

D. People become ill easily if they eat these lobsters.

3.The author's purpose of writing the text is most likely to _____.

A. discuss　　 B. report

C. advertise　　 D. introduce
