Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialization, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.
At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages. Often spoken by many people while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 Languages: the Americas about 1,000, Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6.000, which means that half the worlds languages are spoken by fewer people than that.
Already well over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico(150). Lipan Apache in the United States(two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.
1.What can we infer about languages in hunter-gatherer times?
A.They developed very fast. B.They were large in number.
C.They had similar patters. D.They were closely connected
2.Which of the following best explains "dominant" underlined in paragraph 2?

Humans and dogs have been working together for thousands of years, and some scientists even believe the two species have been living with one another for thousands of years. While having a dog will not improve your health if you never wanted a dog in the first place, dog lovers can benefit from living with them.
1. Most of us know the benefits of exercise, but it can be a struggle to find the motivation to get up and get moving everyday. A dog provides strong motivations, and can make your daily walk or run less lonely and more fun.Moreover, you'll bum extra calories when helping your dog walk and doing brief training exercises with your dog. For some people, going for walks alone is scary, but a dog can make runs and walks feel more secure.l know that with Ranger.I have to walk him every day, and he's always ready each morning.Sometimes we even have an afternoon or early evening walk, which is better for my health.
2. There's no doubt that dog ownership does come with some stresses, from making sure you've applied their weekly bath to worrying if your dog will get along with the other dogs at the dog park. But the benefits of pet ownership more than outweigh these small stresses. Research shows that a few minutes spent petting an animal. lowers blood levels of the stress hormone, which contributes to tiredness, weight gain and aging, and your pet can help kill its negative effects. A few minutes playing with your dog every day also releases powerful ¨feel-good" hormones that continue to function in the bloodstream.
3. Many people living alone worry about thieves, and a dog can help give owners a sense of security. Thieves are less likely to break into a house with a barking dog, and your dog can help you feel less lonely whether you're just spending the night by yourself or living alone long-term.If your dog is older and struggles to move around, you can still rest easy knowing that your dog will get to a robber before you do.
4. People who have regular positive interactions with others tend to live longer and be happier, and pets provide you with a valuable opportunity to meet and interact with other people. Even if you're shy, it's easy to strike up a conversation with another person if you're both talking about your animals. Visits to the dog park and meet--ups with other pet owners also provide pet owners with opportunities for interactions.If you're still anxious about meeting new people, consider joining a message board or online group for people with similar pets to yours. You'll quickly find yourself making new friends in addition to learning a lot about your best friend - your pet!
5. In a fast-paced, high-stress world, depression and anxiety are at an all-time high. But pet owners have fewer mental illnesses, and animals are even used as treatment for people suffering from mental illness. If you struggle with depression, an animal can help you avoid such problems. The exercise and stress release you get from spending time with your pet may even reduce the effects of depression. Dog owners are also less stressed than people who don't own dogs, and reduced stress is strongly related with lower blood pressure, a longer life span, greater happiness and improved health.

For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth.Once a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.
The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was traveling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a closeup picture which the spacecraft took just 3 seconds before it crashed into the comet.
“Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like an American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion.
The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.
The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second. The aim of the mission was to study for the first time the interior of a comet.
The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.
1.How many hours did it take for the spacecraft from the earth to touch the comet Tempel 1?
A. About 2,500. B. About 3,500.
C. About 4,500. D. About 5,500.
2.Which of the following shows the possible orbits and positions of the comet Tempel 1?
S=Solar P=Pluto
T=Tempel 1
A. B.
C. D.
3.Which of the following is the closest in meaning to the underlined word in Paragraph 5?
A. Position. B. Relation.
C. Inside. D. Distance.
4.The author’s main purpose in writing the passage is to________.
A. inform people the discovery of a new comet
B. show the power of America in space
C. introduce the knowledge of comets
D. introduce an experiment

We human beings haven’t been good friends to animals. For thousands of years, we have been polluting the environment, making it hard for animals to live on the planet. We have been killing animals for their fur, feathers or meat, or simply because they are dangerous. As a result, many kinds of animals have disappeared forever. Hundreds more are on the endangered list today.
Should we care about animals? Of course we should. If animals of a certain kind all disappear, they will never come back again. Animals are more than just resources of things we need. Every kind of animal has its place in the balance of nature. Destroying any kind of animal can lead to many problems. For example, when farmers killed large numbers of hawks, the corn and grain that the farmers stored were destroyed by rats and mice. Why? Because hawks eat rats and mice. With less and less hawks to keep down their numbers, rats and mice multiplied quickly. And if people kill too many birds, more and more insects will eat the crops.
Luckily, we’ve realized that we shouldn’t kill animals any more. And people are working hard to save those animals that would disappear soon. The government also passed laws to protect the endangered animals. In fact, quite a few countries have passed such laws. These laws forbid the killing of any kind of animal on the endangered list. We should try our best to protect and save the endangered animals.
1.The text calls on us to__________.
A.keep animals at home B.protect the environment
C.protect the endangered animals D.know more about the balance of nature.
2.Why do people kill animals?
A.Animals cause many serious problems.
B.They kill animals for something they need.
C.Animals destroy their natural resources.
D.They kill animals to protect the environment
3.The example that farmers killed hawks shows that__________.
A.there were too many rats and mice
B.hawks are the most important in the nature
C.animals are good food resources
D.every kind of animal is important in nature

Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.
“Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”
This may not________sit well with________pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don’t have to feed it, you don’t have to walk it, it won’t make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.
It’s not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It’s the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.
As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn’t need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.
So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn’t have a heartbeat might not be a far-fetched dream.
1.What does the underlined phrase “sit well with” means?
A.be refused by B.be beneficial to
C.make a difference to D.receive support from
2.What are the advantages of robot pets?
a. They are plastic and feel smooth.
b. Owners needn’t worry about them when going out.
c. They can help cure allergies(过敏).
d. They save space and costs.
A.ab B.bc
C.bd D.cd
3.We can learn from the passage that___________.
A.Sony is the first company to produce robot pets Aibo.
B.People can develop strong bond(联系、关系) with their robot pets.
C.Rault thinks robot pets still have a long way to go.
D.Robot toys may help people care more about living beings.
4.The passage mainly tells us___________.
A.the advantages of robot toys B.the popularity of robot pets
C.living pets are dying out. D.robot pets are coming.
