While only about 200 astronauts have had the excitement of looking down at Earth and commanding systems on the International Space Station, actually thousands of everyday middleschool students have experienced by Middle School Students, or EarthKAM, a camera system.
EarthKAM is an educational activity and outreach(扩展)investigation that also results in remote Earth sensing and observation. Using the Internet, the students control a special digital camera fixed aboard the space station, enabling them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest from the unique advantage point of space.
While EarthKAM offers a powerful way for students to investigate Earth from the unique perspective of space, it is also inspiring the next generation of flight controllers for space programs—involving university students to control and operate the camera system and related activities from the ground.
In the interview, Brion Au, one of the investigation developers at NASA's Johnson Space Centre, said，“EarthKAM is a payload(有效载荷)by students, for students. They are in charge. This system provides a viewpoint that the astronauts have...it's just aweinspiring！”So far, students have captured more than 40,000 photos of the Earth from the space station as it orbited the Earth once every 90 minutes, traveling at 17,500 miles an hour. The team at EarthKAM posts these photographs online for the public and participating classrooms around the world to view.
Au explains that this education investigation is inspiring students to explore the world by examining Earth, while promoting social studies, art, geography, science, technology, and math, among other important lessons involving research and teamwork. EarthKAM was started by Dr. Sally Ride, originally flying on the shuttles. The camera is located in the window Observational Research Facility, also known as the WORF, one of many the station's research facilities.How have thousands of students experienced similar excitement as astronauts?

Linda Evans was my best friend—like the sister I never had. We did everything together: piano lessons, movies, swimming, horseback riding.
When I was 13, my family moved away. Linda and I kept in touch through letters, and we saw each other on special time—like my wedding (婚礼) and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address (地址) Unknown. ” I had no idea how to find Linda.
Over the years, I missed Linda very much. I wanted to share (分享) happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.
One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name. “There must be thousands of Wagmans,” I thought, but J still wrote to her.
She called as soon as she got my letter. “Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother. ”
Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled. And there’s one thing that Linda and I know for sure: We won’t lose each other again!The writer went to piano lessons with Linda Evans _______.

When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬) elders. Unluckily, this rule led to my very first embarrassment in the United States.
I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive(敏感) Americans are and how they dislike the description “old”. I then walked back to the table and apologized to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.
In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.
However, in the United States, people think “growing old” is a problem since “old” shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.
After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.

Have you ever been in a meeting while someone was making a speech and realized suddenly that your mind was a million miles away? You probably felt sorry and made up your mind to pay attention and never have daydreaming again. Most of us from earlier school days have been told that daydreaming is a waste of time.
“ On the contrary,” says L.Giambra, an expert in psychology（心理学）, “ daydreaming is quite necessary. Without it, the mind couldn’t get done all the thinking it has to do during a normal day… .
You can’t possibly do all your thinking with a conscious（有意识的） mind. Instead, your unconscious mind is working out problems all the time. Daydreaming then may be one way that the unconscious states of minds have silent dialogues.”
Early experts in psychology paid no attention to the importance of daydreams or even considered them harmful. At one time daydreaming was thought to be a cause of some mental illness. They did not have a better understanding of daydreams until the late 1980s. Eric Klinger, a professor of psychology, is the writer of the book Daydreaming. Klinger says, “we know now that daydreaming is one of the main ways that we organize our lives, learn from our experiences, and plan for our futures… Daydreams really are a window on the things we fear and the things we long for in life.”
Daydreams are usually very simple and direct, quite unlike sleep dreams which may be hard to understand. It’s easier to gain a deep understanding of your life by paying close attention to your daydreams than by trying to examine your sleep dreams carefully. Daydreams help you recognize the difficult situations in your life and find out a possible way of handling them.
Daydreams cannot be predicted; they move off in unexpected directions which may be creative and full of useful ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy.
So the next time you catch yourself daydreaming, don’t stop. Just pay attention to your dream. It may be more important than you think.In what way are daydreams different from sleep dreams?
| A．Daydreams help to develop an unconscious mind. |
| B．Daydreams are not so easy for us to control and direct. |
| C．Daydreams help us to handle more difficult situations |
| D．Daydreams are easier for us to understand. |
Professor Eric Klinger believes that _______.
| A．our fears and longings in life are shown in our daydreams |
| B．we may study our experiences just through our daydreams |
| C．daydreaming is one of the important ways that we recognize our lives |
| D．we should be able to tell our futures by having daydreams |
The writer of the article thinks that ______.
| A．daydreaming is more helpful than sleep dreams |
| B．many artists and scientists are famous because they have daydreams |
| C．professor Eric Klinger has a better idea than L. Giambra |
| D．daydreaming with an unconscious mind will do good to health |
Which of the following is NOT TRUE according to the passage?
| A．Daydreaming was once regarded as a cause of mental illness. |
| B．Experts began to have a better understanding of daydreams in the late 1980s. |
| C．Scientists believe that we can know daydreams before having them. |
