    People who enjoy a dream-filled sleep are better at recalling information and making links between facts when waking. But recharging with a shallow (小睡) offers no such mental improvement, the research suggests. The results of the study added to the growing body of evidence that Rapid Eye Movement (REM) sleep is very important to the brain’s ability to form strong memories.
    An average night's rest includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night. This means adults getting less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to memorize: Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.
    In the recent study, participants were shown groups of three words and asked to find another word that can be associated with all three words. They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups didn't improve, but the REM sleep group improved on their morning performance by an average of almost 40 per cent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain occurs during REM sleep.
    It is believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information from useless information. This process may take place as memories are removed hem one art of the brain to others.

    Last weekend I went to the Summer Palace as usually. At about noon, I was enjoying my reading near a lake while suddenly I hear someone crying for help. I went up to see what was happening. I was shocking to find a little child struggling in the water in the distance while many peoples were standing by without doing anything. Without any hesitation, I had pushed through the crowd as I took off my coat, but jumped into the water quickly. I managed to reach him and carried him back to safety. To his great relief, the kid was saved. I was proud what I had done. I wish everyone could give the hand when someone else is in need.

    阅读短文，并按照题目要求用英语回答问题。
    In college, Spring Break （春假）is usually associated with the beach, parties and sleepless nights, bringing about relaxation, free time and friends. Students who wish to spend their break doing something productive and rewarding, however, may choose to participate in the Alternative Break Program. It places college students in communities both at home and abroad.
    The Program allows students to take part in various projects dealing with issues such as literacy （识字）, homelessness and the environment. It includes helping kids with their lessons, raising money for families in need and collecting data for environmental research.
    The hope is that, by getting themselves involved in different environments, students will have the opportunity to learn about members of communities and broaden their view. In turn, they will incorporate (融合) their experiences and lessons learned into their own communities. In a word, the Program aims to encourage students to be active citizens and engage themselves in making a difference in society.
    In the spring of 2006, about 36,000 students in the USA participated in the Alternative Break Program.
    Samantha Giacobozzi, now director of the Program, has been on five alternative break trips herself, including trips to New Orleans, India and Dominican Republic. “I was a student who went on alternative break trips and had my life totally transformed by that experience,” she said. “Every year, we meet many students who have attended the Program. You can see changes in their life that are connected with their alternative break experiences.”
    The Program began in 1991.Today, it has become increasingly popular with college students in the United States.
    小题1:Who may choose to participate in the Alternative Break Program?(within                       10 words)
    小题2:Wha is the aim of the Program?(within 15 words)
    小题3:What is the meaning of the underlined word "transformed" in Paragraph 5?( 1 word)
    小题4:What is Samantha's attitude toward the Program?(within 10 words)
    小题5:If you take part in the Program, which project are you interested in? And why?(within 15 words)
