Health experts predict that soon, more people will die from cancer than from AIDS, tuberculosis (结核病)and malaria combined（疟疾）. 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(结肠) 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 (乳头瘤病毒). 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(检测). 小题1:根据短文内容完成句子填空(每空限填一个单词)。 From the first paragraph of the passage, we know __________ will be the ________ killer soon. 小题2:根据短文内容完成句子填空(每空限填一个单词)。 According to the passage, in developing countries more people are dying from cancer because of  ___________ ____________ 小题3:根据短文内容回答问题。 According to the passage, in which countries will cancer increase fastest ? ____________________________________________________________________. 小题4:把短文中划线句子译成汉语。 _____________________________________________________________________ 小题5:根据短文内容用一个完整的英文句子回答问题。（10个词左右） What can governments do to stop the increase of cancer ? （one thing is OK） _____________________________________________________________________
