Health experts predict that soon, more people will die from cancer than from AIDS and tuberculosis and malaria combined. They expect that by 2010, cancer will become the world's leading cause of death.

Experts say one reason for more people dying from cancer is that more people are smoking cigarettes in developing countries. Forty percent of the world's smokers are believed to live in China and India.

The WHO report estimates that 12 million people will be found to have some form of cancer this year. It predicts that more than seven million people will die early as a result of cancer. And more than five million of new cancer cases will be found in developing countries.

Without new treatments, the WHO 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 separate report in December said the number of men and women dying of cancer in the United States had dropped for the first time on record. The report in the Journal of the National Cancer Institute said the drop was mainly the result of fewer cases of lung cancer in men. In women, it resulted from fewer cases of breast

cancer.

The American Cancer Society says governments can do things to help prevent the increase in cancer cases and deaths. And the cancer society says health officials and governments should invest more in cancer research and early detection.

For a 400-year-old art form, opera had a bad fame: overweight actresses singing the words which were hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $145 a performance, opera goers also had a certain appearance in people's minds: rich, well-dressed and old.

But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to keep opera alive and take it to a younger and not so wealthy audience.

Opera producers have found that to attract this crowd, they need to associate opera with the common people. That means no formal suits, old-style theatre or bank-breaking ticket prices. And because young people don't or won't come to the

opera, companies are bringing the opera to them, giving performances in such usual places as parks, libraries and public schools.

The Houston Grand Opera's choice is the public library, where it performs \operas\shortened version of child-friendly operas. This summer's production is Hansel & Cretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists' Training Programme.

22.What is the main idea of the passage? A) Opera is only for rich people. B) Opera is famous for its history.

C) Young people are not interested in operas.

D) Opera companies are trying to keep operas alive. 正确答案为 D 你选对了!

解析:

D)。根据短文中提到的But now opera companies around the country… in an attempt to keep opera alive… audience以及上下文可知,本文主要讲述的是歌剧公司正在努力将歌剧变“活”,以此来吸引年轻但不富有的观众,故D)为答案。

23.Why do opera companies prefer to perform smaller versions? A) It is hard to find long versions.

B) They can make people interested.

C) Short versions are easy to perform.

D) They can be performed in public libraries. 正确答案为 B 你错选为 D!
