Honeybees are disappearing for unknown reasons around the United States.Last winter, bees disappeared from 23 percent of American beekeeping businesses.Causes of the phenomenon, however, have remained a mystery.
Now, scientists from several universities and the United States Department of Agriculture say they have a possible explanation for the bee decline(数量下降).It is a little known virus called Israeli acute--paralysis virus (IAPV).The virus kills bees.Researchers in Israel first described it in 2004 , but until now, bee experts hadn’t paid much attention to it.
When trying to find out why the bees were disappearing, a research team at Columbia University studied bee colonies (群体), some with and the others without decline.The research turned up large numbers of two types of fungi (真菌) once suspected of causing the bee decline.The research results, however, showed that the fungi were almost as common in colonies without a decline as they were in colonies with a decline.The researchers concluded that the two fungi probably weren’t the cause.
Studies of the presence of IAPV, however, showed more interesting information.In those studies, done by a team at Pennsylvania State University in University Park, the virus showed up in 83 percent of samples from colonies with symptoms (症状).Only five percent of samples from symptomless colonies had it.
Scientists still don’t know whether IAPIV can single--handedly cause the bee decline.They believe that even if the virus is making colonies sick , it could have a partner in crime.It’s possible, for instance, that insects or chemicals in the environment weaken bees, making them more likely to catch IAPV.
Scientists are still trying to figure out how IAPV came to the United States.The United States currently allows bee products to be imported from Canada, Australia, and New Zealand.If it turns out that this trade is spreading disease, the rules might eventually change.

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog.
Many countries are making rules to flight pollution. Factories must now clean their water before it is thrown away, and they mustn’t blow dirty smoke into the air.
We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

第二节 读写任务(共1小题,满分25分)
阅读下面的短文,然后按照要求写一篇150词左右的英语短文。
According to Shenzhen Daily, the city’s vehicle population has reached over 1 million and 80 percent of the vehicles are private cars.
Nowadays more and more families own private cars. Private cars, as the product of modern civilization, have been playing a vital role in people's daily activities. Firstly, private cars are a convenient means of transportation. You can go wherever you like. Secondly, there is no doubt that private cars will have a great impact on the economic growth. The rapid car industry growth will contribute much to keeping the country's economy growing at a higher rate in the near futrue.
But every coin has two sides. The development of the private cars will bring about a series of problems. For example, the polluted air given off by cars will do great harm to our health, too many private cars will lead to traffic jams and a great deal of energy will be wasted and so on.That is why many people suggest we should go cycling in the city instead.
However, I think that the advantages of owning a car outweigh the disadvantages. Therefore, it seems to me that China should increase its output of automobiles and enlarge the private car market. We should take advantages of private cars and make them serve us better. Meantime ,we hope that satisfactory solutions to these negative problems will be found soon.

It was a Sunday and the heavy storm had lasted all night.The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realised it was a good day for fishing and invited my sister and me to go with him.I was only 14 and fishing had never been my thing, but I decided to go all the same.I’m so glad I did.
On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape.After all, it was protected by the arms of a bay that had only one tiny channel to the sea.As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby.We couldn’t believe it —there aren’t any whales along the coast here.The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale — actually as big as our boat — was obviously stuck and could not move.The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves.” She’s trying to help her baby, but on the wrong side,” my father said.At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently.With our several gentle pushes the big hump turned over and disappeared under water.Then it swam up right beside its mum.They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction.We hurried up to the whales and tried to lead them towards the bay channel.Slowly, they let us lead them, sometimes rising from the water right beside us to breathe — and to give us a trusting look with those huge eyes.Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half.That was the simple and lasting beauty of the day, Nearly four decades later, I still look back fondly to that golden day at sea.

2.The harbour survived the storm owing to__________.
