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(鹰), 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(繁殖) 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. protect the endangered animals.
B. find out more about the balance of nature.
C. keep animals grow quickly.
D. protect the environment.
2.The example that farmers killed hawks shows that__________.
A. there were too many rats and mice
B. animals are very beautiful and interesting.
C. every kind of animal is important in nature .
D. animals are good food resources
3.What is the author’s attitude towards the future of endangered animals ?
A. Doubtful B. Uncaring C. Optimistic D. Negative

For thousands of years，we have looked for ways to measure time. Early humans found that the regular movements of the sun，the earth，the moon，and the stars made good ways to measure time. The rising and setting of the sun were used to distinguish day from night.
But，eventually，people needed to tell time more accurately，or exactly. So，by using the sun’s position in the sky，they divided the day into dawn，morning，midday and evening.
Then it was noted that the sun cast a changing shadow as it moved across the sky. Time could be told more accurately by setting up a stick and marking the positions of the sun’s shadow. It was the ancient Greeks who divided each position of this “sundial(日晷)” into hours.
But the sun doesn’t always shine. So，for the past 6,000 years，many other ways of keeping time have been tried. Slowburning candles were divided into hours，and the hourglass was invented. When all the sand in the top of an hourglass has shifted to the bottom，an hour has passed.
Later，the pendulum(摆钟)，with its regular backandforth movement of weights，was used to move the hands on a clock. Pendulums are still used in grandfather clocks.
Today，even more accurate clocks are in use，such as batteryoperated quartz clocks（石英钟），digital clocks，and clocks run by electrical tuning forks and tiny atoms. These atomic clocks are the most accurate clocks ever invented. The exact time can be kept to within 1 second a century.
1.Humans in the old days used ________ to tell day from night.
A．the rising and setting of the sun
B．batteryoperated quartz clocks
C．atomic clocks
D．digital clocks
2.A sundial works by ________.
A．tracking the movement of the stars around the sun
B．marking a shadow cast by the moving sun
C．burning candles in the sunlight
D．watching the stars
3.Which of the following was NOT used in the past to measure time?
A．An hourglass. B．A sundial.
C．Digital clocks. D．A pendulum.
4.Which of the following ways of measuring time is ordered from the least accurate to the most accurate?
A．Sundial，pendulum，sun.
B．Atomic clock，quartz clock，sundial.
C．Sun，pendulum，atomic clock.

We have most friends at the age of 26 after having spent the first quarter of our lives building up our friendship circle, new research has claimed.
The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends.Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.
The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school，with about a fifth saying they meet them at work.
Social networks such as Facebook and Twitter now also play a major role in building new friendship.The research points out that 25 to 34yearolds make 22 friends via Facebook, compared to 18 to 24yearolds who make 12, and 35 to 44yearolds who make just four.
Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes，giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference.”
Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% to drift away from childhood friends.
With growing pressure being put on friendship these days，it's important to make time for our friendship.
1.How many friends can a 20yearold college student make via Facebook?
A.4. B.12.
C.18. D.22.
2.In Paragraph 5，the author is trying to tell the readers________.
A.how important making friends is
B.that friendship is not easy to keep
C.how much has been done to keep friendship
D.School time is an important period to develop friendship.
3.The underlined phrase “drift away from” in Paragraph 6 means “________”.

For millions of years, coral reefs（珊瑚礁）have provided homes and food for thousands of different living things. Fish and sea birds share the reef with other creatures. Now these beautiful places are in danger. 1. Scientists have found that more than one-fourth of the earth’s coral reefs have been ruined so far. Another quarter will disappear in ten years’ time. Unless things change, all of the remaining reefs may die within your lifetime.
Some people think that coral is stone because of its rough（粗糙的）, hard surface. But coral is an animal. Tiny polyps（水螅体）form the coral reefs. 2. These colors come from the algae（海藻）living inside the coral. Billions of coral polyps stick together. New ones grow on the dead ones. This happens year after year. Over time, the coral builds up a reef. The reef rises from the ocean floor until it almost reaches the sea’s surface. It takes coral 500,000 years to build a huge reef. 3.
The coral reefs have been harmed mainly in three ways. The first factor is pollution on land. The pollutants run with rainwater into streams and rivers, which carry the poisons into the ocean. 4. So they will be easily infected with diseases. Another cause is people. People have broken off pieces of coral, which they want to sell or keep as souvenirs. People have dropped sticks of dynamite（炸药）into the water to catch more fish. The worst problem is the heating up of the oceans. Higher ocean temperatures kill the important food source for the coral—the algae, the tiny greenish-gold water plants that live on coral. 5. The coral turns white and dies. Scientists call this coral bleaching（珊瑚白化）. The bleached part of the coral reef cannot recover.
A. They come in many different colors.
B. However, humans have taken less than 100 years to destroy it.
C. This has blown up parts of the reefs.
D. When the algae die, the coral loses both its food and its color.
E. So are all the sea plants and animals that depend on them.
F. Chemicals from the poisons kill reefs or make them weak.
G. Many of them might not even last that long!

Alpacas(羊驼) are members of the camel family, having lived in South America for thousands of years. Their fur gives the animals a teddy bear_like appearance. Alpacas are too small to be used as animals of burden but are valued only for their fur. Generally, their lifespan is around 15 to 20 years.
Alpacas are social animals that live in family groups made up of a male, females and their young. They are gentle, elegant, curious, intelligent and observant. They are safe and pleasant to be around, moving gracefully and slowly around the field, and are therefore unlikely to run into or over anyone, even small children. Occasionally, an alpaca will spit snd kick, but the soft padded(有爪垫的) feet usually do little more than just“get your attention”.
Because these animals are environmentally friendly and need so little grass and food, you can usually raise from two to eight alpacas on an acre of land with grass or hay. A single, 60 pound bale(大捆) of hay can generally feed a group of about 20 alpacas for one day. Alpacas also require access to plenty of fresh water to drink.
Alpaca fur is used for making knittedd and woven(编织) items, just as sheep’s wool is.These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles(针织品) in South America, and sweaters, socks, coats and bedding in other parts of the world. The fur comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States.
1.According to the text, alpacas can be best used_______.
A. for long distance rides
B. to protect home
C. for children to play with
D. to carry heavy goods
2.What does the underlined part in Paragraph 2 probably mean?
A. Alpaca’s kick can’t hurt you.
B. Alpacas want to draw your attention.
C. You must look out for Alpacas’ attack.
D. You should pay more attention to Alpaca
3.If you have 5 acres of land to raise Alpacas, how much hay do you need a day at most?
A. 60 pounds.
B. 120 pounds.
C. 100 pounds.
D. 180 pounds.
4.According to the last paragraph, which of the following is true?
A. Alpaca fur is a kind of sheep’s wool.
B. Alpaca fur is only used for making sweaters in Australia.
C. The US produces the most Alpaca fur in the world.
D. Alpaca fur produced in Peru comes in the most natural colors.

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.

Humans have daydreamed for thousands of years, and yet, these days, spare moments are filled with using our smartphones and other devices—going through social media, listening to podcasts, responding to emails—leaving us little time to let our minds wander.
1. When you’re in a daydreaming state of mind, you can imagine or pretend your own version of events.
“My most creative moments come when my brain is allowed to rest” says Megan King, a designer. But she is addicted to her smart phone. 2. According to Nielsen, Americans spend 10.5 hours a day consuming media. And UK residents are close behind at almost 10 hours a day, according to eMarketer.
3. This may seem a small change, but its effect, on the way our minds work and on our collective creativity could be serious. 4.
Over years of studies, researchers have found that our brain has two separate attention systems — an external one and an internal one. The internal attention system, which is activated(激活）during daydreaming, is called the default network(默认网络).
The default network is particularly active when we are thinking about ourselves, thinking about the past, thinking about the future. 5.
If both systems can’t be active at the same time and we’re spending 10 hours a day in one attention system, it begs the question: what is that doing to our brains — and our ability to come up with creative ideas?
A. Daydreaming is the opposite of our dreams.
B. This extended screen time has made some of us uncomfortable sitting alone with our own thoughts.
C. Daydreaming is how we access our big-picture state of mind.
D. In fact, it could be preventing your ability to come up with fresh, creative ideas.
E. We can’t really have both attention systems active at the same time.
F. People spend too much time on screen suffer from headaches.
G. She's not alone.
