三、阅读单选

All dreaming starts with sleep. When we sleep there are four stages（阶段）that we go through.

Stage One is the lightest stage of sleep. In this stage of sleep someone can be awakened by low sounds or slight touch. Stage One sleep happens through-out the night. It often reappears as a transitional state of sleep following arousal（刺激）during the night. When Stage One does reappear during sleep, it only lasts thirty seconds to one minute. Young adults spend ten to fifteen minutes a night in Stage One sleep.

Stage Two sleep may have some of the slower eye movement Stage One, but in general Stage Two sleep is free of any eye movement. Another feature of stage two is arousal. Since Stage Two is a deeper sleep than Stage One, it will take more arousal to awaken a person from this stage of sleep.

Stage Three sleep as well as Stage Four is usually referred to as a slow wave sleep, which basically means a slow frequency（频率）of brain thought. There are no visual eye movements in this stage. Again in Stage Three it takes even more arousal then Stage Two sleep, to awaken a person from this state of sleep. Most of the dreams remembered take place during stage Three Sleep.

Stage Four sleep is the deepest of sleep. This is where the body and mind gets the most rest. Brain frequencies increase slightly in Stage Four sleep. In this stage of sleep people begin their dreams. When a person is dreaming you can visually tell by the movement of the eyes. Scientist measure deep sleep by “R. E. M.” which simply means “rapid eye movement”. What they measure is the amount of time your eye moves in Stage Four sleep and also brain activity along with frequency. Once again much more arousal is needed to awaken a stage four sleeper.

Nowadays, people are living a fast-paced (快节奏) life and they are not patient (耐心的) enough. For example, we spend much time looking through websites every day. But most of us don’t read the news very carefully. Study shows that people spend just 15 seconds on a piece of news, then they will move on to some other interesting things quickly.

You may think that people will slow down a bit more when they look at the great works of art (艺术品) in the museum. But you are wrong. Most visitors only spend 10 seconds looking at a piece of art. They spend more time taking photos.

Today, many museums in the world really want to make some changes, so over 170 museums around the world are holding “Slow Art Day” to encourage visitors to enjoy art works slowly and deeply. They are asking their visitors to spend at least 5-10 minutes looking at just one work of art. They believe that in that way people can notice different information about the work and get a lot from it.

Phil Terry, who started Slow Art Day, said, “It helps us to see art in a new way and open our eyes!”

Dear Frank,

How is it going? I am very glad to receive that English dictionary. What a great gift you sent to me! Thank you so much! Each time I come across a new word, I will look it up in the dictionary. It is so helpful that I always take it when I go to school.

I also prepare a present for you. I know you are fascinated with traditional Chinese culture. So I decide to send you a piece of paper cutting made by myself. It is in the shape of a rooster, which is your Chinese zodiac sign. As we know, paper cutting is a traditional Chinese art form. The paper, usually red, is folded before it is cut with scissors. During the Spring Festival, paper cuttings are put on windows, doors and walls as symbols of wishes for good luck and a happy new year.

This piece of paper cutting carries my best wishes to you and your family. I hope you will like it. Look forward to hearing from you.

Yours,

Li Hua
