This year some twenty-three hundred teenagers（young people aged from 13 —19）from all over the world will spend about ten months in U. S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.

Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.

Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected — much harder. Students rose respectfully^① when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.

       Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.

       “Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”

       At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize^② American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”

Microsoft founder Bill Gates said that he planned to give away almost all of his vast^① fortune, largely to the cause of global health, during the course of his lifetime. With an estimated^②worth of more than $ 40 billion, according to Forbes, the project will be no small feat^③for Gates. Having already provided the Bill & Melinda Gates Foundation with $ 24 billion to address global health issues, Gates said that eventually his entire fortune will be put towards the cause except “a few percent left for the kids.”
So what has made the richest man in the world to channel his resources so heavily into one interest? Gates believes that “the equality of opportunity” in which Americans take such pride needs to extend to other nations around the world. Improving the health of the populations, he says, has proven to be an essential method in helping poor countries to be financially^④ successful. “National borders allow inequalities,” said Gates, “We all need to take a more global view, rather than just saying my country is doing well. We have to step up these health issues, knowing how few resources are going into them.”
Gates said that both his parents set good examples to him as a child. His father, William H. Gates, was the head of the local Planned Parenthood, and his mother, Mary, volunteered for the United Way. As he gathered his fortune, Gates knew he would eventually want to give back as well, but he didn’t expect to devote himself whole-heartedly to one project until he was about 60.
However, Gates, 47, began to question his ability to wait that long. “It seemed there was a real time urgency,” Gates said, “I started to think, how many lives could I save before then?”
