Write NO MORE THAN 3 WORDS for each answer.
United Nations officials say now fewer people than they thought are infected with the AIDS virus.
Last year, the agency known as UNAIDS thought that 39.5 million people were living with HIV. On Tuesday it reduced by 16% to a little more than 33 million.
Agency officials say the low number reflects better information form more countries. The agency reduced the number for five African countries: Angola, Kenya, Mozambique, Nigeria and Zimbabwe.
Also, UNAIDS says it now believes the number of new HIV cases per year reached a high in the late 1990s at more than three million. This year, it thinks that 2.5 million people became infected, and 2 million people died of AIDS.
Luckily, better treatments are saving lives, and more people are getting the drugs.
Yet even as the number of new infections has dropped, UN officials say AIDS is still one of the leading causes of the death worldwide, and the major cause in Africa. African death rates remain high, they say, because treatment needs are not being met. Sub-Saharan Africa had almost 70% of the new cases of HIV reported this year. UNAIDS officials say this is a sharp reduction since 2001, but there is a need to further improve research method.
Billions of dollars are being spent preventing and treating HIV. Experts worry that the new number may lead to a drop in financial support. But UNAIDS officials say they do not change the need for immediate action and more money. They warn that in some countries, infection rates that were falling are rising again now.

Section B
Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit. Write your answers on your answer sheet.
Richard Wagner was a German musician who lived in the mid-19th century. He gained fame by writing opera, a form of performance combining singing, music on instruments, and drama.
Wagner’s life and work have been very controversial(有争议的). While he wrote excellent music, many people think his operas are too dark and serious, lacking tile fun common in operas written before his time.
Wagner, on the other hand, thought the opera of his time was too simple. He wanted to make opera a serious form of art that combined drama and music to tell deep stories that would have a strong effect on the audience.
Some people thought Wagner’s new kind of music was too different from the operas they were used to hearing. Wagner agreed with them. In fact, he didn’t call his works “operas” at all, using instead a German word that means “Musical Festival” or “Musical play”.
While many people today still do not like Wagner’s operas, they cannot deny that Wagner had a lot of influence on opera as a form of art. Wagner invented the tradition of turning off the lights before starting a play. He also was the first person to make the whole audience sit down for an entire play. Today, almost all operas are performed in this manner.
Wagner as a man was even more controversial than Wagner as a writer of music. He hated Jewish people, slept with his friends’ wives, and made many people angry, which we would today think of as evil. Some would say he was a good musician, while others would say that he was a bad musician. But it would be difficult to say he was not an important person in music and in the world.
