Millions of years ago, dinosaurs (恐龙) controlled the earth. And there were different types of dinosaurs on the earth. Some of them were no bigger than chickens, but all of them had very small brains (大脑). Later on, there weren’t any dinosaurs. What happened to them?
In the days of dinosaurs, the whole earth was warm and wet. There were many green forests. But the earth changed slowly all the time. When parts of the earth became cold and dry, the forests there died. Then dinosaurs could not find enough food to eat. This must be one reason why dinosaurs died out.
What’s another reason? We can make a guess. New kinds of animals came to the earth. Some had big brains and were fast and strong. They could kill dinosaurs. Some ate dinosaur eggs, too.
There may be other reasons that we do not know about. Each year, people will find some dinosaur footprints (脚印) and bones. Scientists are trying to tell us more about dinosaurs.

【推荐1】Today, by carefully choosing dog parents, humans have created many different kinds of dogs. Each kind has its own look and talents, and its own role within human society. Here are three examples of “a dog’s life” in the human world.
Today, many hospitals let specially trained dogs in to bring love and cheer to patients. Shaynee is a therapy dog. She visits children who are in hospital. Dogs like Shaynee help patients feel calm and at peace, which can be hard in a busy hospital. They help both children and adults stay strong during long hospital stays, and even help them get better.
Today, some beagles (小猎犬) work in airports for the government. They are part of the program called the Beagle Brigade. A beagle is good for the work because of its powerful nose, and ability to follow smells. The Beagle Brigade’s job is to smell everything that comes into the country. They make officers notice illegal (非法的) fruits, vegetables and other foods in luggage or in mail. The beagles do the job far better than any human could.
While some dogs are working hard, others are free to spend their days resting and playing. Across the world, many pet dogs are treated like children. Many have their own rooms and all the things a dog could want. Some even have their own clothes. Many of these pets spend their days playing, learning to follow, or even going to classes. Their owners give them the best, and enjoy doing so.
Whether as workers or objects of affection (钟情), dogs have become helpful to humans in many ways. There are plenty of advantages for the dog, too. Many kinds of wild dogs have nearly disappeared from the Earth. However, the domestic dog’s special place as “man’s best friend” has allowed it to survive in a human world.

She is not at school but at the Olney Farmers and Artists Market in Maryland. What does she do there? Is the 11-year-old girl farming? No, she isn’t. She is selling handcrafted clay (粘土) elephants. Miriam Gardsbane and her friends make these elephants in their free time. Miriam Gardsbane doesn’t use the money she gets to buy clothes or funny toys. She uses the money to help elephants.
“Elephants need help,” Miriam said after her day at the market. “A lot of people don’t know what’s going on with these animals.”
Two years ago, Miriam watched a TV program about elephants. Some people made elephant shows for money in streets. How poor these elephants were! They should be free in the forest. That was why Miriam decided to do something to help elephants.

【推荐3】Making Friends with Ducks
In traditional pet stores, you can buy an animal to be your companion at home. But there’s a new kind of “pet store” where you can spend some time with animals and just walk away without taking any of them with you. What really matters is to be there.
My colleagues and I visited one of these stores in the Sanlitun neighborhood of Beijing. We were looking for Call ducks (柯尔鸭), a Dutch species of pet ducks. They are famous for their cute looks and their sky-high prices—one of them can easily cost a few thousand yuan. Since we were not planning to spend so much on a duck any time soon, visiting them in one of these places—what I'd call “mini-zoos”—seemed to be the perfect choice.
There were five Gall ducks at the store and we spent a good three hours with them. We learned a lot about the species.
Call ducks are not as obedient enough to follow what they are told to do as dogs, so playing with them takes a lot of chasing from our side and quacking (呱呱叫) from theirs. Also, don’t expect them to be house-trained—one of the ducks actually pooped (排便) while sitting on my lap. But none of this took the pleasure out of holding them in my hands and touching their full chests.
That’s the magic of animals—you are refreshed again.
1. According to the passage, the new kind of pet stores ________.A.provide the service of experiencing | B.sell Gall ducks at a very high price |

A.Sanlitun is a good choice to relax |
B.the trip to mini-zoos is very refreshing |
C.spending time with animals is fashionable |
D.keeping pets at sky-high prices is unnecessary |
A.To Own Is Traditional | B.To Touch Is Magic |

【推荐1】Giant pandas have been living on Earth for millions of years. Other animals that lived long ago, such as stegodons and smilodons, have since died out. But we still have pandas with us today. Pandas can change their diets to fit into different environments, according to Wei Fuwen from the Chinese Academy of Sciences.
Researchers studied the bones of 12 giant panda fossils (化石). They found that pandas went from being meat eaters to becoming plant eaters over time. They mainly ate bamboo, as they still do today. Other large meat eaters had no interest in bamboo, so pandas could live safely in bamboo forests. That is one of the reasons why they have been around for so long.
In addition, pandas are very strong and have great bite force (咬合力). They can also climb trees. Both of these abilities helped them stay alive in the past.
However, pandas are facing some problems. There are fewer pandas in the world today. They are dying out mainly because of habitat loss. People have cut down forests to build houses and farms. This has caused pandas to lose both their food and their homes.
Pandas also have problems giving birth to babies. Female pandas can only get pregnant (怀孕) once a year and they are very choosy about their mates. And because they mainly eat bamboo, their milk is low in nutrients (营养). This makes it harder for their babies to survive.
1. According to Wei Fuwen, pandas haven’t died out because they ________.
A.have thick fur to live through the cold weather | B.can change their diets to fit into new environment |
C.can run fast to escape from their enemies | D.can kill other bigger animals around them |
A.Climate change. | B.Natural enemies. | C.The loss of their habitat. | D.Dangerous diseases. |
A.twice every five years | B.once a year | C.twice a year | D.three times every four years |
A.panda milk is low in nutrients | B.their parents don’t take care of them |
C.they are very short when they’re born | D.they aren’t used to cold weather |
Reading people’s character from their ears is an old science. In very old times people thought that a person with big ears had a good and generous character. They thought that a person with pale, small ears was dangerous. They also thought that the shape of the ear showed if a person was musical. Today, too many people believe that the size and the shape of the ear help you know if a person is musical.
Ears are all different, and each characteristic has a meaning. Next time when you look at a person, see if his ears are large, medium-size or small. Look at the lobes (the lowest part of the ear). Do they stick to the face? Ears that are always red mean a person may easily get angry, or he / she just has high blood pressure (高血压). Ears that are always cold and pale mean a person has a nervous character. And a big inside hole of the ear means a person is musical.

【推荐2】To many students, joining social media “circles” is now more important than making new friends in real life. And it’s easy. If you have a mobile phone, you can download (下载) many things such as Sina Weibo, QQ and WeChat.
“I love to check my friends’ updates (更新). I also enjoy news and humor shared on social media,” said Wang Wei, 14, from a middle school in Shenzhen. While enjoying these, Wang distances himself from real life. I love playing the plane-shooting game on WeChat, but have no interest in playing chess with my classmates,” said Wang.
Deng Yunyun 14, from Xuhui Middle School in Shanghai, said that social media has influenced their normal life. Last month, his school held a basketball match, and a student hurt his leg. Instead of giving him some help, students were busy with updating WeChat blogs about the accident. “I think they need to learn to balance their real and online lives, and what worries parents and teachers a lot is safety.” said Deng.
“Many students are happy to tell their interests and personal information to their social media ‘friends’. And this could bring them danger,” said Miss Wang, a teacher from Shenzhen middle school. “For example, the use of WeChat’s shake-shake allows users to connect to other users nearby. Also police warn about the risks (风险) of making friends in this way.
“Be careful. Do not use the locating (定位) function at any moment, do not give your name, and do not post the photos of your community,” said Wang.

【推荐3】Chinese New Year is a time when families and friends get together. Food plays a very important part in the celebrations.
At the New Year’s Eve dinner, families often have eight or nine different dishes. This is because eight and nine are lucky numbers. The Chinese word “eight” rhymes with the word for good fortune. The word “nine” means long-lasting.
Many foods at the feast have a special reason for being included: dumplings, because they look like golden nuggets; a whole fish or chicken to represent togetherness and good fortune; long noodles, to bring long life; oranges, because they are perfectly round and are symbols of good luck. Also, the Chinese word for orange sounds a lot like the word for success. It is a New Year’s tradition to take oranges when visiting people’s homes.
Sticky rice cakes and sweets are also served. There is a legend about a Kitchen God who reports to the Jade Emperor in heaven on whether families have been good or bad during the year.
