Winter sports need to be in cold places. Have you ever imagined one day people go to other planets to hold the Winter Olympics?

Mercury (水星)

It’s the closest planet to the sun. In the daytime, the temperature can be up to 430℃ but at night it cools down to -200℃. There’s one area that the sun can never reach. There’s a lot of ice there. Maybe we can go speed skating and figure skating (花样滑冰) there!

Mars

The temperature on Mars is between 140℃ and 30℃. At the north and south poles of Mars, there are areas covered by ice and snow. There is also a big mountain called Mount Olympus, So maybe we can ski on Mars!

Pluto (冥王星)

Pluto is a dwarf planet far away from the sun. It’s very cold there, about-229℃. There’s a lot of ice. It’s even harder than steel. So maybe we can go sledding (滑雪械) on Pluto.

Picture the scene: It’s midnight. You’re very hungry after studying for a long time. Then you see a nice pie in the fridge. Should you eat it? It seems that you shouldn’t for many reasons, because it may be bad for your brains.

Scientists have long known that eating late at night can make us put on weight. But now a new study has shown that late-night eating may also be bad for our brains—it might hurt our ability to learn new things and store memories.

“We believe that late-night eating may affect our learning by affecting (影响) the parts of the brain that control learning and memory,” Dawn Loh. PhD, a project scientist at the University of California, Los Angeles, said. “We believe the timing of when we eat is the main cause of the bad memory.”

For the study, the researchers did an experiment (实验) on mice. The mice were either allowed to eat during the daytime or during the night. They had the same amount of sleep and food. Then the researchers tested the brains of the mice and noticed that the mice eating during the night were less able to remember things well.

So think twice before the midnight snack—it might be bad for more than your weight.

4. The writer asks readers to picture the scene in the first paragraph to ________.

A．interest them and lead into the topic

B．tell them a story about late-night eating

C．give them some information about the scientist

6. The purpose of the experiment on mice is ________.

A．to find out whether eating late can affect memory	B．to check the brains of different mice
C．to find out how much food mice need daily	D．to show mice are not good at remembering things

7. Which of the following could be the best title of the passage?

A．Eating snacks affects memory	B．Late-night eating hurts brains
C．Staying up late is bad	D．Keep away from snacks

Many people believe that goldfish only have a seven-second memory, but Roy Stokes, a 15-year-old schoolboy from Australian Science and Mathematics School has just finished an experiment to tell us that it is not true. He shows everybody that goldfish are smarter than we think.

“I don’t believe that they have a seven-second memory because animals need their memories, so they can know where the food is,” he said.

He did the experiment in a small tank of goldfish. “I decided to get a red logo and just feed them next to the logo. Every day I put it in and dropped food around it,” he said.

“At first they were a bit afraid of it, but by the end of the three weeks, they were actually almost coming before I put the food in.”

After leaving the goldfish alone for a week, Roy put the red logo in the tank again.

“They remembered perfectly well,” he said. “They actually had a time faster than the three feeds before I left.”

The goldfish showed that they not only could store information, but also had the ability to get it back at a later date.

Colum Brown, a researcher at Macquarie University in Sydney, has studied fish behavior for more than ten years. He says his studies show that fish are smart and that they know how to avoid enemies (躲避敌人) and catch food like any other animal. As an experienced expert, Colum thinks that Roy’s experiment is really good.

8. Roy began his research by ________.

A．discussing with his classmates	B．making friends with goldfish
C．asking his teacher for advice	D．questioning a popular idea

9. What is the right order of Roy’s experiment?
①put the logo back into the tank
⓶feed the goldfish next to the logo
③leave the goldfish alone for a week
④take out the logo
⑤put a red logo into the tank
⑥find a tank of goldfish

A．⑥⑤②④③①

B．⑥④⑤③①②

C．⑥①⑤③②④

D．⑥⑤③②④①

10. What does the underlined word “store” in paragraph 7 probably mean?

A．shop

B．keep

C．sell

D．forget

11. Roy’s experiment shows that ________.

A．goldfish have a seven-second memory

B．goldfish are smarter than we think

C．goldfish can avoid enemies like any other animal

A smile shows that a person is happy. For example, a person may smile when he or she is happy with a grade on a test. Or a person might smile if a friend told a funny joke. People smile for many different reasons. But smiles are more than just a way for people to show that they are happy. There are other good reasons to smile often.

First, it is easier to smile than to show unhappiness. In fact, it only takes 17 muscles (肌肉) to smile. On the other hand, it takes 43 muscles to show unhappiness. So give the muscles in your face a rest and smile!

Second, smiles are nice. People may try to look nice on the outside by exercising or wearing nice clothes. However, there is a famous saying: a smile is the best thing a person can wear. That is because it is easy to be around someone who is smiling and happy. Almost no one wants to be around someone who is unhappy all the time.

Third, smiles are helpful. Both smiling and laughing can quickly spread from one person to another. If one person smiles, people around him or her want to smile, too. Similarly, when a person laughs, people tend to laugh with them. If a person is sad, the best thing to do is to share a smile or laugh. It is the easiest and cheapest way to cheer someone up.

Finally, smiling and laughing are very good for the body. Even if you are mad or sad, try smiling. You’ll find that it will be hard to stay mad or sad for very long.

12. In what situation does a smile show that a person is happy?

A．When he makes 43 muscles on the face work together.

B．When he is happy with the grades on the tests.

C．When his friend tells him a scary story.

D．When someone around him is sad.

C．It is free.

D．It is easy.

14. Which of the following sentences is TRUE?

B．No one wants to be around the people who are happy.

C．If a person is sad, the best thing to do is to have a rest.

D．If you are angry or sad, you’d better not smile.

Nobody imagines that, one day, they might be left on a desert island but it could happen. So it’s a good idea to learn a few key skills that would help you to live if it happens to you.

    16    

The first thing you need to do is to make a shelter (躲避处) on the beach, near the sea, so that you can watch any ships that pass your island. Your most important task is finding a way to get off the island, so you can’t miss any chances of seeing somebody who could save you.

    17    

It’s a good idea to build your shelter near some trees. It will provide shade (树荫) from the hot sun. If you get sunburned, you won’t be able to do what you need to stay alive. If there were coconut trees, you could also use the oil from the coconut to protect your skin.

    18    

Clearly, you need to stay out of the way of any dangerous animals or insects. Make a bed that is off the ground if you don’t want to share your bed with snakes or other creepy crawlies.

    19    

You will need about ten liters of fresh water per day. If you can’t find a river on the island, rain water will be your best chance of living. You need to make containers (容器) to catch and keep rain water. Large plants with huge leaves are a good way to collect water. But never drink sea water—it will make you even thirstier.

    20    

Finally, you need to do anything possible to be seen and saved. If you don’t have what you need to make a fire, then you can write “HELP” on the beach using rocks to spell out the word.

A．Make sure somebody sees you

B．Make a shelter and watch the sea

C．Drink sea water when you’re thirty

D．Keep away from dangerous animals

E．Stay away from the hot sunshine

F．Collect enough fresh water
