For hundreds of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy.In fact, sunlight makes us feel good.When sunlight hits our skins,our bodies produce a vitamin. Vitamins are natural chemicals(化學(xué)物質(zhì))which we all need to stay healthy.Sunlight helps our bodies produce vitamin D.Vitamin D helps our bodies make a special chemical.This special chemical affects our brains(大腦)and makes us feel happy.For example, there are long, dark winters of little sunlight in Sweden and Norway,so many peple in these countries often feel sad.Without much sunlight, their bodies produce less vitamin D.Without enough vitamin D, their bodies make less of this special chemical which makes them feel good.To help the people in these countries feel better,special “sunrooms”with artificial(人造的)lights have been built.People can go there and get “sunlight”for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
小題1:Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?
A．Weather.B．Actions of others.
C．Personality.D．Age.
小題2:Which of the following is true about vitamin D according to the passage?
A．It is a kind of artificial chemical.
B．It makes us worried by affecting our brains.

D．It is in the sunlight.
小題3:What can we infer (推斷) from the passage?
A．We feel good when we are in the bright cool weather.
B．We will be happy when we are caught in the rain.
C．All people in Norway and Sweden feel sad in winter.
D．The more vitamin D you have, the happier you’ll be.
小題4:What may be the best title for this passage?
A. Why Do We Feel Sad?            
B. The Weather Influences People’s Emotions.
C. People Need More Vitamin D.      
D. We Can Hardly Change the Weather.

小題1:D
小題2:C

Having a cheetah as a pet in the house? Does it sound scary to you? But for a family in South Africa, one cheetah is treated as a VIP (Very Important Person) in the house.
The big cheetah is named Jolie, after the film star Angelina Jolie.      小題1:     She can often be found eating from the kitchen table, taking a short sleep on the sofa, or even sleeping on Lucy and Jeff’s bed. The big cat also sleeps and plays with the Browns’ other pet, the more usual one — a sheepdog (牧羊犬).      小題2:
Having a cheetah as a pet is unusual. At first, Mrs Brown wasn’t willing to keep a cheetah as a pet. She said, “    小題3:     But we are now happy that we did it — she is part of the family.”
Just like her name, four-year-old Jolie has achieved a celebrity status (名人地位) in the Browns’ hometown. Fans often come to their home to take pictures of her.      小題4:
However, a cheetah is always a cheetah.      小題5:    “She makes a lot of mess in the house, urinating (小便) everywhere and chewing everything. It’s her wild instincts (本能),” said Mrs Brown.
There might be some problems of having a cheetah as a pet in the house, but some unusual fun must also be waiting ahead.

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.     Life today has brought new problems. One of the biggest is pollution （污染）. Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.     Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog（煙霧）.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air.     We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.
When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.
Scientists have now shown that pet dogs also have “l(fā)eft gaze bias(左視偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.
Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.
“Recent studies show that the right side of our faces can express emotions better than the left. If  true, then it makes sense for dogs and humans to see the right hand side of a face first.”
小題1:Why are dogs seen as man’s best friend according to the passage?
A．Because dogs are the closest animals to humans.
B．Because dogs can read the emotions in humans’ faces easily.
C．Because dogs can understand us better when we feel sad.
D．Because dogs are good at expressing emotions.
小題2:The dogs’ left gaze bias helps them _______.
A．get along well with humansB．express emotions quickly
C．have more understanding friendsD．remember more new faces
小題3:The passage mainly wants to tell us that _______.
A．dogs have been man’s best friends for thousands of years
B．humans have a “l(fā)eft gaze bias”
C．the “l(fā)eft gaze bias” works on all animals
D．dogs can read emotions the same as humans

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射)light(光). We see color because most of the things reflect light. Something is red, because it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat.The darker the colour is, the less light is reflected, the more light is taken in. So dark-colored(深色的)clothes are warmer in the sun than light-colored(淺色的) clothes.

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?

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.

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
