缺詞填空

In most situations, light helps us see. But nowadays humans are using so much that it is in fact a kind of pollution.

When it comes to looking at the night sky, too much light makes it d  1.  for us to watch some of life’s most wonderful views: stars, p  2.  and even galaxies(星系).

According to scientific research, about 2, 500 stars can be seen by the human eye without u  3.  any special equipment(設(shè)備). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big c  4., people cannot see the sky filled with stars like they did in their childhood.

Light pollution affects more than just our view of sky. Research s  5.  that lots of nighttime light can harm wildlife, too.

When birds fly to a  6.  place over cities, they sometimes get lost by the brightness and fly in circles(圈) u  7. they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.

Too much light at night m  8.  even affect human health, but scientists are not sure of that. They are still learning more.

In order to prevent things from going w  9., governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are r  10.  needed.

Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life, too.

Some years ago, I went to Australia for a meeting with my friend, Chris. We decided to drive across the country to Brisbane after the meeting ended. The drive was going to take four days and most of it was across the desert, so we had to take food, water, and extra gas(汽油) w  1   us.

Health experts predict that soon, more people will die from cancer than from AIDS, tuberculosis (結(jié)核病)and malaria combined(瘧疾). They expect that by 2013, cancer will become the world's leading cause of death.

Experts say one reason that more people are dying from cancer is because they are smoking cigarettes in developing countries. 40 percent of the world's smokers are believed to live in China and India alone. Other things including high fat diets and fewer physical activities are also believed to be pushing the numbers more.

Rates (比率) of breast cancer (乳腺癌) in Japan, Singapore and South Korea are now 3 times what they were 40 years ago.

The W.H.O. report says that 12 million people will be found to have some kinds of cancer this year. It predicts that more than 7 million people will die early as a result of cancer. And more than 5 million of the new cancer cases will be in developing countries.

The number of cancer cases and deaths from cancer are expected to increase one percent each year. Experts are predicting the largest increases will be in China, Russia, and India.

Without new treatments, the W.H.O. says, the number of new cancer patients could reach 27 million a year by 2030. The number of deaths could reach 17 million a year.

A report in December said the number of men and women dying of cancer in the United States had dropped for the first time .The report in the Journal of the National Cancer Institute said the drop was mainly the result of fewer cases of lung(肺), prostate(前列腺) and colorectal(結(jié)腸) cancer in men. In women, it resulted from fewer cases of breast and colorectal cancer.

The American Cancer Society says governments can do things to help stop the increase in cancer cases and deaths. One idea is to provide poor and developing nations with vaccines(疫苗) that help to stop some cancer-causing infections (感染). One example of a cancer-causing infection is human papillomavirus (乳頭瘤病毒). This virus(病毒) can cause cervical cancer in women.

Another suggestion is more support for cigarette-control programs. And the cancer society says health officials and governments should pay more in cancer research and early detection(檢測).
