We have always been interested in the moon. 2000 years ago people already knew it moved around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes(望远镜) to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on Earth. This was because they believed the moon had once been a planet(行星) that had been caught in the earth’s gravity(重力) millions of years earlier.
In 1969 moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of Earth. They believe very early in its history, maybe 4 million years ago, something about the size of Mars(火星) hit Earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even though our ideas about the moon may change again, we will still be interested in it.
1. In the passage the writer wants to tell us ___________________.
A.why people are interested in the moon
B.how ideas about the moon have changed over time
C.where the moon came from in the past
D.that people have finally learned the truth about the moon.
2. Before 1969 most scientists thought the moon was ___________________.
A.part of the earth billions of years earlier
B.older than the earth
C.a planet caught by the earth’s gravity
D.made of the same things as the earth
3. From this passage we can learn that ___________________.
A.scientists in the past were not clever
B.the earth was once part of the moon
C.we now know everything about the moon
D.new information brings new ideas

【推荐1】Dyslexia(阅读困难症)is a condition that influences one’s ability to read, write, spell, and listen. Someone with dyslexia has a hard time making the connection between the way letters look and the sounds of words. Though learning may be more difficult for kids with dyslexia, it doesn’t mean that they aren’t smart. It means they have trouble translating what they see, hear, or write into meaningful information.

So, what causes dyslexia? Scientists believe a trouble in the brain makes decoding(编译)languages difficult for some people. Although there is no way to cure it, some doctors think that if caught early, dyslexia can be improved. One way to do this is by teaching readers to practise reading those words aloud. Many dyslexia people discover their own ways, such as listening to books on tapes or asking for more time to complete tests.

文章大意:本文主要介绍了凌乱的桌面带给人们的创造力和感受等。

【推荐2】No one wants to work at a messy desk. But does a messy desktop (桌面) actually mean that? Not all disorders mean you mess everything up.

People who prefer a messy desk have their own ideas. Some think it makes them comfortable. Some believe it helps them focus more easily. Messy tables can make it easier to focus on the tasks, just like some writers can write patiently (有耐心地) in a noisy place. Others may be the people who want to do things perfectly (完美地). For those who strive for perfection (完美), tasks are either 100% or 0% done. So they usually put away the less important things and do the most important ones perfectly, which leads to paper mountains on the desktop.

Many people are described as untidy, careless and slow because of messy desktops. However, when we see the desks of Albert Einstein or Mark Twain, things might change. Clearly, the world welcomes uniformity (一致) and order, and it also never refuses regular (有规律的) disorder.

Research shows that people working with a messy desktop are probably more creative and like to take risks. For example, in an experiment (实验) done by Kathleen Vohs, people in the messy group came up with more interesting and creative ideas about the new uses of ping-pong balls than a organized one. Vohs says, “Messy environments seem to make people to think up fresh ideas.”

But a messy desk might not be the best choice all the time. When you need new ideas, a messy desk might be a good choice; but when you want to do a task quickly and successfully, it seems better to make a desk clean and tidy.

根据短文内容选择最佳答案。
1. The underlined phrase “strive for” in the passage means “________”.
A.be interested inB.work outC.try hard to achieve
2. Some people prefer a messy desk because ________.
A.it makes them uncomfortable

C.they are lazy and untidy
3. What can you learn from Paragraph 3?

B.People may be successful although they have messy desktops.
C.People can finish the tasks perfectly as long as they keep their desks clean.
4. The experiment done by Kathleen Vohs shows that ________.
A.people working with a messy desktop think up fresh ideas more often
B.people working with a tidy desktop always try new things
C.a messy desktop has a bad influence (影响) on people’s minds
5. What’s the best title for the passage?
A.Messy Desk: Do People Need to Change It?
B.Messy Desk: Does It Make People Comfortable?

文章大意:本文主要介绍了一个关于老年人的记忆力的研究成果。

【推荐3】

“What’s the name of the man living next door? I can’t remember it right now.” Have you ever heard your grandparents ask questions like this? Usually, we think old people’s memories (记忆力) become bad because their brains (大脑) can’t work quickly. But a team of German scientists has a different idea.

“The human brain works slower in old age,” said scientist Michael Ramscar, “but only because they have kept much more information over time.”

The findings are a result (结果) of many computer simulations (模拟) of learning and memory. Scientists let the computers read words and learn new things each day. When the computer “reads” only so much, its result in memory tests is the same as that of a young man. But if the computer learns much more than that, its result is the same as that of an older man. It is slower because more information makes the computer’s database (数据库) grow and the computer has more data to work with —it takes time. This is the same as old people.

   Think about this. A man knows two persons’ birthdays. Another man knows the birthdays of 2,000 people, but can only match the right man to the right birthday nine times out of ten. Can you say that the first man has a better memory than the second one? The fact is that “The larger the library you have in your head, the longer it usually takes to find a word,” Benedict Carey, a science reporter for the New York Times, wrote in a report about the study.

1. The writer uses the question at the beginning to _________.
A.make readers think of their friends
B.say that many people have bad memories
C.make readers interested in the passage
D.show why older people like asking questions
2. The scientists did the study by _________.
A.asking old people questions
B.reading books and some useful reports
C.following the lives of a group of old people
D.using computers to simulate man’s learning and memory
3. Why do old people forget other people’s names easily?
A.Because they have a very poor memory.
B.Because they are too old to remember things.
C.Because there is something wrong with their brains.
D.Because there is too much information in their brains.
4. What would be the best title for the passage?
A.Is it better to be old or young?
B.How can man use their brains?
C.Do old people have poor memories?
D.What are scientists’ new findings on brains?
