Science has told us so much about the moon that it is quite easy to form an idea of what it would be like to go there. It is certainly not a friendly place. As there is no air or water, there can be no life of any kind. Mile after mile there are only plains(平原) of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountains shadows, it will mean moving from terrible cold into great heat. The moon is also a very silent(安静的) world, for sound waves (声波)can only travel through air. But from the moon, you can see a friendly sight(景色). Our earth is shining more brightly than the stars. It looks like a large ball, coloured blue and green and brown.

（1）、What kind of place is the moon?

A、It is a friendly place. B、It is a lively place. C、It is a nice place for man to live. D、It is a lifeless place.

    Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?
    Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists(心理学家)are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.
    Consider your emotions. You might think that emotions are the enemy of decision making, but in fact they are a part of it. Whenever you make up your mind, your brain's emotional centre is active. University of Southern California scientist, Antonio Damasia, has studied people with damage to only the emotional parts of their brains , and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.
However, making choices under the influence of an emotion can greatly affect the result. Take anger, for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.
    All emotions affect our thinking and motivation（动机），so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.

Most people hope to have a memory which helps them succeed in study, work and life. Can memory be improved? Luckily, hundreds of studies in the past 50 years have already given us a definite answer.
A healthy lifestyle keeps your brain young and memory sharp. First of all, it is necessary to have a healthy diet. Eating more food rich in B vitamins and Vitamin E, such as vegetables and lean meat, helps you have a better memory. Doing exercise can keep your brain alive, too. Proper exercise provides much needed oxygen for the brain. Running, riding a bike, swimming and even walking two or three times a week are helpful. Moreover, getting enough sleep is important. Only when your brain gets a good rest, can it work well. The healthier your lifestyle is, the better your memory will become, but do not expect a sudden change—it takes a long time to make a difference.
Memory skills help you remember things better. The following three are the most widely used. Chunking is a way of remembering a piece of information by cutting it into smaller ones. For example, to memorize a ten--digit telephone number 2127983630, you can divide the digits into three groups: first 212, then 798, and lastly 3630. This method is far more effective than remembering a string of 10 digits. Organization means organizing information into groups of the the same kind. For example, trees, grass and flowers are plants; tigers, panadas, horses and cows are animals. Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with.
However, memory skills will hardly work if you don't understand the information. What's more, only a regular review can make the memory last long. That is why students are always advised to go over what they have learnt after one day and then after three days, and then use it as regularly as possible.
Human brains are like muscles that need nutrients and exercise to become stronger. If you make a few lifestyle changes and try some memory skills, you can certainly improved your memory.

You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it's not! In fact, the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table. Your brain controls everything that you need to do to save that glass from falling. First your eyes check out what's going on, then tell your brain, and your brain decides how quickly you need to react(反应), and then your muscles(肌肉) go into action. That is just from your brain. No computer could ever come close to that!

The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ(器官). There are about 100 billion tiny, tiny little cells(细胞) in your brain. There are so many that it would take you over 3,000 years to count them all!

Your brain stops growing when you're 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won't be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for long-term memory establishment(建立). It is realized that the brain is the second organ in the body as the heart that never stops during human lives.

So everyone should be proud of such a gift of nature.

There are all kinds of animals on our planet. Some are sweet, but some are not; some are small, and some are tall. Here are four pictures of some of the funniest, friendliest faces. But remember, although they look nice, it doesn't mean they are always friendly.

Not all dogs are so cute, but most of them are pretty friendly. When you come near an unfamiliar(不熟悉的) dog, remember to hold out your hand, so he can smell you and see that you mean no harm.

Cows love to eat grass, and they eat quite a lot! You needn't be afraid of this quiet farm animal. But don't run at a cow in a field or touch one, unless you are told by an adult it's okay.

Horses are big, beautiful animals, but they can be easily angry. A horse might jump up if she hears a loud noise, or kick her legs if you come near too suddenly. All horses, like humans, are different.

Chimpanzees(黑猩猩) make funny faces and put on a real show at the zoo, but believe it or not, they can be very dangerous. And they are strong too--much stronger than humans--so you should never make a chimp mad!

An atlas is-a book of maps. Atlases are made with different kinds of information about different parts and areas of a country or the world. They are prepared for desk use or travel use.

Desk atlases are made for different groups of people with different needs. For example, students may use desk atlases to help learn Geography, and other people may use desk atlases to study a place. A popular type of the latest atlas shows the recent fact of the world. New atlases are often carefully produced to help people learn about the changes, such as name changes, boundary(界) changes and other important new information. A desk atlas can also have some different maps of the same place. For example, an atlas may include maps showing population and important products of a place.

Travel atlases usually show the information about both natural and man-made features(特点). So it is not surprising to find universities, airports, forests, rivers, roads as well as cities, towns and villages in them. A travel atlas is often the first thing people need when they want to start a trip in a strange place.

It often has a map of a whole country, and a map with more special information of each important place in the country. Take the atlas of the United States as an example, it often has a map of the whole country and then a map of each of the fifty states.

A travel atlas may also point out the beautiful natural places. In the USA, the atlas may include national parks such as the Yellowstone National Park and some others to show the beauty of nature and interesting places to tourists.
