Einstein was born in 1879 in Germany. As a child, he was slow to learn to talk. As a pupil, he was backward. But when he was fourteen years old, he became clever. He taught himself maths from textbooks. He studied hard because he wanted to be a physicist.
In 1901, Einstein began teaching. In 1902 he continued his studies at the University of Zurich. Several years later, he formulated(系統(tǒng)地闡述)his famous Theory of Relativity(相對論).To most people the law of relativity is difficult to explain. But once Einstein explained it very well to a group of young students. He said, "When you sit with a good girl for two hours, you think it is only a minute. But when you sit on a hot stove for a minute, you think it's two hours. That is relativity."

I was in a shopping mall recently, and I decided to go and get a cup of tea. As I was making my way to the coffee shop, I noticed an old gentleman rather poorly dressed sitting on a bench nearby. I knew from the first sight that he was in need of some kind of help. He had a little lunch in front of him and was wholeheartedly enjoying it.
There was a young man in front of me in the line also waiting to be served. The young man handed the servant a twenty-dollar bill and asked for an orange juice as well as a favor. The servant looked at the young man with a little surprise, not fully understanding him. The young man asked her to give the juice to the old gentleman eating his lunch outside on the bench. The young man also told her that he would be watching every second so that she would be completely safe at all times. Later, there was a wonderful exchange between the waitress and the old man. I only wished I had taken a photo of the smiles on both of their faces.
As I was thinking about this event later on, I wondered why the young man didn’t just perform this act of kindness himself. I thought he was hoping that this act of kindness might inspire others to do something for the old man as well. Thinking of the happy smiles on the old man’s face, I felt how worthwhile it is to help others.
1.The underlined word “favor” in Para. 2 refers to________.
A. passing the young man a cup of orange juice
B. buying lunch for the old man
C. exchanging meals with the old man
D. giving the juice to the old man
2.Which of the following can be used to describe the young man?
A. Kind and considerate B. Generous and proud.
C. Rich and friendly. D. Humorous and helpful.
3. In the author’s opinion, the young man asked the servant to take the juice to the old man so that____________.
A. the old man could probably accept it
B. he would become famous for his good deed
C. more people would be inspired to do good deeds
D. he would become a friend of the servant

Have you ever felt a sudden feeling of joy because you heard a favorite song playing? Then you know that music can have a strong effect (影響) on your emotions. 1.It can help get you out of a bad mood (心情) or stay in a good one, says Alicia Ann Clair, professor at the University of Kansas.

You can lower stress at work with music, too, by playing relaxing tunes (曲調(diào)). 4. "If you listen to them all day long, you' ll stop noticing them," Dr. Clair explains. Then the music won' t have any effect.
5. "To feel energetic, start with something relaxing, and then gradually increase the speed and beat," says Dr. Clair. For example, first play some nice slow love songs, and then listen to something more energetic. When you want to calm down after a busy week at work, just do the opposite.
