11．South African researchers at the international AIDS conference in Vienna，Austria have announced major progress in the fight against the disease．The researchers say their study shows a gel（胶体）substance reduced the risk of HIV infection among women who used it．
The gel contains tenofovir，which is a common drug used to treat people with HIV，the virus that causes AIDS．
The study was done by South African scientists with the Center for the AIDS Program of Research in South Africa．Almost nine hundred sexually active women between the ages of eighteen and forty took part in it．All were from KwaZulu-Natal，South Africa．Half were given the gel containing tenofovir．The other half were given a gel without an active substance．They were told to use the gels twelve hours before having sex and again within twelve hours after having sex．
The study lasted thirty months．Women who used the tenofovir gel reduced their risk of HIV infection by thirty-rune percent．And the study found that the women who used the gel more often had even better results．Women who used the gel more than eighty percent of the times when they had sex had fifty-four percent fewer HIV infections．
Health experts say the results of the study show that tenofovir gel can empower women．However，researchers say they will study why the gel did not protect in all cases．Some scientists say the amount of tenofovir in the gel may be too low．Others say some women may have had sex with infected men who had very high amounts of the virus．The researchers also say they will carry out more studies to confirm the results．

12．当前不少文学作品被改编成电影．有人选择看电影，有人则喜欢读原著．请你以"Film or book，which do you prefer？"为题，按照下列要点写一篇英语短文：
1、看电影：省时、有趣、易懂

3、我的看法及理由
注意：1、词数：100词左右．文章题目已给出（不计入词数）．

Film or book，which do you prefer？Some of us think that it is better to see the film than to read the book in the original．The reason is that it takes less time to understand the whole story．Besides，the film is usually more interesting，and it is easier to follow．
Some others have just the opposite opinion．They think that they can get more detailed information from the original．Meanwhile，the language in the book is possibly more lively and beautiful．
Personally，I agree with the second view．Actually I have more reasons for it．I think I can stay at home，reading quietly in a situation of my own，and what's more，I am able to better understand the author's ideas．In a word，to read the original work is better than to see the film based on it．．
