Aids today
Aids, the short form for acquired immune deficiency syndrome, is caused by a virus called HIV, which enters a person’s blood and attacks the body’s immune (免疫的) system. There is no cure for HIV or Aids, and after a person has been infected, he or she will always carry the virus. Sometimes, infected people have no outward symptoms.
HIV and Aid
s are spreading across the world at a frightening rate, with about 14,000 people being infected daily. The virus is spread in three ways -- through unprotected sex, blood-blood contact and mother-to-child transmission. Unprotected sex is the most common way that the virus is spread, accounting for 75 percent of adult infections worldwide.
Although many people are familiar with Aids and how it is transmitted, more than a few people hold the view that HIV and Aids are an African problem because the infection rates there are very high. However, HIV and Aids are a problem all over the world. Since the disease was discovered in the 1980s, it has become a serious problem in many places, infecting over 60 million people worldwide. According to the World Health Organization estimates from 2005, more than 4 million children had died from Aids, and more than 14 million children had lost their parents to Aids. All of this makes it clear that something must be done to stop this deadly disease.
The government is working hard to control the Aids epidemic and has opened labs to test and monitor the disease. In 2003, the government also started providing free drugs for Aids patients in need.
The United Nations has been very involved in fighting HIV and Aids around the world for many years now. UNAIDS, an organization founded in 1996, helps prevent the spread of Aids. The work includes providing infected people with help from doctors and testing for people. The organization also offers programs that teach Aids prevention to young people and sets up treatment centers.
To be a real gentleman, you should know that true forgiveness is one of the most remarkable qualities a human can possess!

Mercy often wears the face of ．And though it usually isn't an enemy in uniform-that we are challenged to forgive,

Public Speaking and Critical thinking
What is critical thinking? To a certain degree, it's a matter of logic -- of being able to spot weakness in other people's arguments and to avoid them in your own. It also includes related skills such as distinguishing fact from opinion and assessing the soundness of evidence.
In the broad sense, critical thinking is focused, organized thinking -- the ability to see clearly the relationships among ideas. ___. The greatest thinkers, scientists, and inventors have often taken information that was really available and put it together differently to produce new ideas.That, too, is critical thinking.
__ _. As the class goes on, for example, you will probably spend a good deal of time organizing your speeches. While this may seem like a purely mechanical (机械的) exercise, it is closely connected wi
th critical thinking. If the structure of your speech is loose and confused, chances are that your thinking is also disordered and confused. If, on the other hand, the structure is clear, there is a good chance your thinking is too. Organizing a speech is not just a matter of arranging your ideas you already have. ____.
What is true of organization is true of many aspects of public speaking. ____. As you work on expressing your ideas in clear accurate language, you will improve your ability to think clearly and accurately. __ As you learn to listen critically to speeches in class, you will be better able to assess the ideas of speakers in a variety of situations.
If you take full advantage of your speech class, you will be able to develop your skills as a critical thinker in many circumstances. This is one reason public speaking has been regarded as a vital part of education since the days of ancient Greece.
A. Rather, it is an important part of shaping the ideas themselves.
B. This may seem take a lot of time, but the rewards are well worth it.
C. It may also help you to know that there is no such thing as a perfect speech.
D. It has often been said that there are few new ideas in the world, only reorganized ideas.
E. If you are wondering what this has to do with your public speaking class, the answer is quite a lot.
F. The skills you learn in your speech class can help you become a more effective thinker in a number of ways.
G. As you study the role of evidence and reasoning in speechmaking, you will see how they can be used in other forms of communication as well.
After ruling the tennis world for almost five years, Roger Federer is adjusting to life at NO.2. But, like any king whose throne has been taken away, the Swiss star is already planning secretly his return to power, beginning at this week’s US Open.
The problem is, many experts think he will never do it. They blame everything from age and tough competition to his racket and psychology.
For years Federer, 27, had enjoyed the view from the top. Competitors saw him as undefeated, and for the most part he was. However, before the 2008 season began, Federer had an illness that stole his strength and clearly affected his play on the court. Ever since, he has struggled to return to form, winning just two of his last 14 tournament
s.
“Twenty-seven is an age when your body starts talking back to you.” tennis great John McEnroe told the New York Times.
Pancho Sefura, another tennis great, noted that Federer is also facing a maturing crop of young talents. “There are too many great players now,” he said, naming Britain’s Andy Murray, 
21, and Latvia’s Ernests Gulbis, 20.
US magazine Sports Illustrated tennis columnist Jon Wertheim suggested that part of Federer’s problem could be his insistence on using a small racket. He says that the smaller head demands ball control. But we see time and again that racket makers try to get players to use a certain stick — one they would like to market to consumers and it has a negative effect the professional game.
Sports psychologist Jim Loehr told the Times that Federer is probably feeling “a sense of doubt” after being considered as undefeated for so long. If Federer is to recover his state of being undefeated, Loehr said he must overcome his doubt. “Federer doesn’t need fame and money. But he has to get better. He has to go to a whole new level. That’s the only way he stays in the game,” he said.
As for beginning his first Grand Slam in ages as the NO.2 seed, Federer said it might be for the best. “Five years almost, I was expected to win every tournament I entered,” he said, “so maybe Rafael Nadal now feels what I had to feel for a very long time. It will be interesting to see how he handles it.”

3.What can be inferred from the passage?
A. Now it is Nadal who has replaced Federer as the No.1tennis player.
B. the racket makers aim at the players’ better performance in games.
C. It is impossible for Federer to return to power.

News that Microsoft made a $44.6 billion bid to buy Yahoo resulted in heated discussions made by many Internet users. Here are some responses:
Diane Burke of Weeks bury, Kentucky
I think it would definitely be an interesting combination. Everyone recognizes the names Yahoo and Microsoft, but everyone also says, “Did you Google it?” Such
a catchphrase is going to be hard to beat.
Shaun Carney of Laurelville, Ohio
I think the merger will provide more competitions for Google. I don’t think the merger will allow Microsoft to develop faster than Google, though. I believe the increased competition this merger brings will force Google to stay on top of its game by offering more fresh and original Internet tools and expanding on the tools it already offers.
Toni Suarez of Hacienda Heights, California
I view the merger as a necessary element in preventing a monopolization. Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!
Rick R. of Edgewater, Florida
It sounds like a disaster to me. If this were to happen, I would stop using my Yahoo e-mail account because I don’t like the feeling of Microsoft spying upon my business. I will sign up for Google.
Antonio Glosser of Kansas City, Missouri
Right now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Microsoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.

A. One.B. Two.C. Three.D. Four.
2.Which of the following statements is NOT true according to the passage?
A. Shaun’s attitude towards Google is passive.

3.The passage is mainly about ______.
A. opinions on the merger of Yahoo and Microsoft
