Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at laughter Clubs around the world—and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. “ Young children laugh about 300 times a day. Adults laugh between 7and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing—it’s universal（通用的） language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.
So, what happens at a Laughter Club？ I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest--I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say“ho ho ho, ha ha ha.” While looking at each other. However,Our bodies can’t tell the difference between fake（假的） laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works!  After ten minutes everybody in the room was laughing for real—and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results!
小題1: In which country was the first Laughter Club started?
A．BritainB．America
C．AustraliaD．India
小題2: How did the writer feel at the beginning of the class?
A．SurprisedB．Pleased
C．NervousD．Stressful
小題3:When did the people in the club begin to laugh for real?
A．After a few minutesB．After a few hours
C．After a few secondsD．After a few days
小題4: Which of the following is true according to the passage?
A．Fake laughter and real laughter are both good for health
B．40% of the people in Laughter Clubs are good friends.
C．Adults laugh more often than children in a day.
D．Laughing is the best way to prevent illness.
小題5: Which is the best title of this passage?
A．Laughing is bad for your health.
B．Laughing is the best way to prevent（預(yù)防） illness.
C．Laughing is helpful for your health.
D．Laughing is the most important thing to you .

任務(wù)型閱讀 閱讀短文，按要求完成各題。（5分）
At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars. Our own planet, Earth, is becoming more and more crowded and polluted. Luckily, we can start again and build a better world on Mars.
First of all, transport should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get to Mars!
Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will produce the food and air that we need. However, can these plants produce water for us? There is no answer now.
There is a problem for us to live on Mars. Mars suck us much less than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies.
There will probably be no school on Mars. Every student will have a computer at home which is connected to the internet. They can study, do their homework and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today. Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will make many people feel ill. The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.
小題1:根據(jù)短文內(nèi)容完成句子填空（每空限填一個單詞）。
In the first paragraph, we can know, Earth is becoming more and more_____ and___ to make  people  want  to live on the planet of Mars.

As we know, it is not easy to build a satellite(衛(wèi)星). Building a traditional satellite usually takes years. The costs can be as high as $250 million or more. Most members of the design teams have worked in the field for a long time. They hold advanced degrees(學(xué)歷) in math, science, or engineering.

But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障礙) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(軌道) satellite.
So far, college students have built and launched(發(fā)射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit take pictures, collect information and send it back to the earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own satellite. A new program called KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas they’ll come up with may be countless.
Education isn’t the only aim of CubeSats because these tiny, technology-filled boxes are  inexpensive to build and can be put together quickly, they’re perfect for testing new technologies that might one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two. Or space junk could gradually increase because CubeSats become more popular.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Someday—perhaps a lot sooner that you imaging—you might get to design, build and launch your own satellite. If you do, you’re sure to have fun. And you might also get crazy about science for life.
小題1:Building a traditional satellite __________.
A. costs $250,000          
B. needs college students      
C. takes quite a long time
小題2:Compared with the traditional ones, the new satellites __________.
A. need long start-up times    
B. are cheap and small-sized   
C. collect more junk in orbit
小題3:The underlined word “countless” in Paragraph 4 probably means “__________”.
A. 無用的                   B. 無價值的             C. 無數(shù)的
小題4:According to the passage, which of the following is true?
A. CubeSats could possibly cause pollution in space.
B. Scientists designed CubeSats for kids to play with.
C. Students can’t design satellites without college education.
小題5:The purpose of the author writing the passage is __________.
A. to tell us that satellite technology can also be learned by kids
B. to show that high technology brings a big change in kids’ life
C. to tell us that kids must study hard to learn satellite technology

How green are you? Do you care about protecting the environment and saving energy? We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you. Remember these three words: Reduce, reuse and recycle.
REDUCE
Reduce means “use less.” Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary--- or maybe the old one will be just as good! When we do buy things, choose local produces if possible, and try not to buy too many things form abroad. It may cost a lot of money to bring them to us.
REUSE
Reuse means “use again.” Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
RECYCLE
Recycle means “change things into something else.” Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
小題1:Why is it better to choose local products if possible?
A．Things from abroad do harm to our environment
B．Local products are much cheaper
C．To choose local products means that we love our country
D．Things from abroad aren’t necessary
小題2:According to the passage, when we find our clothes are out of fashion, what should we do?
A．Throw them away
B．If they are still suitable, keep them
C．Clean the floor with them
D．Give them to others and buy new ones
小題3:What is the helpful activity in our daily life?
A．To shop with plastic bags
B．To use paper cups
C．To collect old newspapers
D．To burn fallen leaves
小題4:According to the passage, which of the following is RIGHT?
A．We should learn to grow vegetables
B．People mustn’t produce waste any more
C．Children are too young to do anything to save energy.
D．The simplest everyday activities are important to protect our world.
小題5:Which of the following is WRONG according to this passage?
A．Always buy new things and throw away old ones
B．Use china cups instead of paper cups
C．Recycle something that can be recycled
D．Think first when we want to buy something

Do you know how important it is to have breakfast? A study of 2,000 teenagers in the US showed that eating breakfast daily is helpful to young people.
According to the study, teenagers who eat breakfast weigh around 5 pounds less than teenagers who do not. Although they take in more calories (卡路里) in the morning, they are more active during the day because they have more energy. This means they burn more calories than non-breakfast eaters. The breakfast does not even have to be very healthy, as eating anything is better than nothing.
The study also showed that eating breakfast keeps teenagers feeling full for longer, so they will not eat too many snacks (零食) later in the day. This is good news as most popular snacks, like sweets and potato chips, are usually unhealthy and full of calories.
Another big advantage of eating breakfast is that it helps teenagers do better at school.This is because it gives them more energy to keep their attention in class.
What's more, a study in the UK showed that adults (成年人) who eat breakfast daily put on less weight and also perform better at work.
Whatever your age is, take time to have breakfast every day.
小題1:The underlined sentence in Paragraph 2 means that _________.
A．teenagers should eat something for breakfast
B．breakfast helps teenagers do better at school
C．breakfast must be healthy with lots of calories
D．the energy makes teenagers active the whole day
小題2:Having breakfast daily makes the teenagers _________.
A．eat fewer snacksB．pat on more weight
C．relax themselvesD．burn less calories
小題3:The passage is mainly about _________.
A．the importance of snacksB．how the adults perform at work
C．the advantages of having breakfastD．losing weight without breakfast
小題4:We can probably read this passage in a (an) _________.
A．story bookB．health magazine
