1 . Thirty-two cases of illegal hunting or trading wild animals have been uncovered involving 33 suspects since a crackdown against illegal wildlife trade was launched on April 10.
Beijing police seized 74 wild animals grouped in China into the first-grade and second-grade state protected animals, including African grey parrots and cockatoos, as well as nearly 50 wild birds and 21 pangolin scales.
On April 16, police in the capital city’s Chaoyang district caught two suspects, who were respectively identified as Liu and Wang, for buying wild animals, and recovered more than 40 wild birds, including one cockatoo and one African grey parrot, at their homes, the statement said, adding the two suspects have been detained (拘留).
In another case, a 35-year-old man surnamed Hu was also sentenced to imprisonment in Daxing district after he was found selling wild animals through QQ, a popular instant messaging tool in the country. He was caught on April 14.
The bureau highlighted the importance of protecting the wildlife, noting Chinese laws and a new decision adopted by the nation’s top legislature (立法机关) have also shown the country’s determination against illegal trade of wild animals.
The Chinese Criminal Law clarifies that those illegally hunting, buying, selling or transporting wild animals on the state protection list, endangered animals or the wildlife-related products will face an imprisonment of more than 10 years and fines if their behaviors are identified as “extremely serious”.
On Feb 24, the Standing Committee of the National People’s Congress, the country’s top legislative body, also passed the decision that clearly states all wildlife on the protection list of the existing Wild Animal Protect Law or other laws, and all wild animals, including those artificially bred and farmed, are not permitted to be hunted or traded.
With the strict crackdown campaign against illegal trade of wild animals on the go in Beijing, the whole nation is attaching great importance to wild life protection.

2 . GPS has completely transformed how we get around. But other animals have long had their navigation (领航) systems built right in.
“We know their eyes are quite sensitive to polarized (偏振的) light and the sky has a particular pattern of polarized light relative to the position of the sun,” Barbara Webb, a researcher at the University of Edinburgh, says.
You can see polarized light firsthand if you take a pair of polarized sunglasses and spin them against the sky-the light passing through the glasses changes. Webb says the insects have polarization like that built into their many eyes. “You can think of it as having lots of sunglasses pointing in different directions.”
But Webb was curious whether there’s really enough information in the sky to give insects an accurate sense of direction. So her team built a sensor (传感器) modeled after a desert ant eye and put it under artificial light meant to simulate the sky. They then put that sensor into a model meant to model the brains of desert ants and other insects. And they found that with the insects’ sensing and processing equipment, they can likely sense direction down to just a couple degrees of error.
A system based on that of insects could someday be a cheap, low-energy choice to GPS. Insects have very tiny brains. A brain the size of a pinhead that’s using hardly any energy. And yet they’re still able to navigate better than we can with GPS, which is surprising. Webb is now working on building a robot that can use light to get its directions.

3 . Satellite, hunger, stars, kerosene lamps(煤油灯), the Milky Way, the Cultural Revolution’s factional civil wars, a light-year, the flood… these seemingly unconnected things combined together and formed the early part of my life, which shaped the science fiction I write today.
As a science fiction writer who began as a fan, I do not use my fiction as a way to criticize the reality of the present. I feel that the greatest appeal of science fiction is the creation of numerous imaginary worlds outside of reality. I’ve always felt that the greatest and most beautiful stories were told by science. They are far more magnificent, grand, involved, profound, thrilling, strange, terrifying, mysterious, and even emotional. Only, these wonderful stories are locked in cold equations(方程式) that most do not know how to read.
There’s a strange contradiction: On Earth, mankind can step onto another continent, and destroy the civilizations through war and disease. But when they look at the stars, they turn emotional and believe that if aliens exist, they must be friendly and kind.
I think it should be the opposite: Let’s turn the kindness we show toward the stars to mankind and build up trust and understanding between different peoples and civilizations. But for the universe outside the solar system, we should be cautious. For a fragile civilization like ours, this is the most responsible path.
As a fan of science fiction, a considerable part of the science fiction I’ve read comes from America. The fact that American readers can now enjoy my book makes me both pleased and excited. Science fiction describes event of interest to all of humanity. It often describes a day when humanity will form a harmonious whole and I believe the arrival of such a day need not wait for the appearance of aliens.
Except from “Author’s Postscript for the American Edition of The Three-Body Problem”

4 . Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere, and so raising the temperature of the earth.
In Europe, eight of the last ten years have seen record high temperatures. On the other hand, the countries around the Mediterranean Sea are receiving even less rain than before. In Sub- Saharan Africa the crops are drying out in the fields and people are dying of starvation. In 1999, the southern United States was struck by a serious of destructive(毁灭性的) hurricanes. Scientists expect such trends to continue, and to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and extreme weather conditions, scientists are closely monitoring sea levels around the world. They are slowly rising, as the northern and southern polar ice caps start to melt. This will have serious consequences for low-lying countries near the sea. Already parts of these places are disappearing under the rising sea water.
According to a new research, one contradictory feature(特征) of global warming is that it will probably lead to a period of much colder weather. Scientists base their theory on what happened the last time the world warmed up, 8,300 years ago. They have discovered that when the ice melted from the northern polar ice cap it became trapped in a lake in northern Canada. As more ice melted, this lake suddenly burst open, pouring millions of tons of freezing fresh water into the North Atlantic. This flood of water prevented the normal flow of water in the Atlantic, which takes warm water from the tropics(热带地区) north to Europe. When this flow of warm water was cut off, temperatures in Europe dropped by between three and eight degrees over the next 200 years. ''That's the concern here,'' says Richard Alley, an American climate expert. ''The climate hasn't varied much in 8, 000 years. But big changes could come back!''

5 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.
1. Why does the author compare the parent-teen war to a border conflict?| A．Both are about where to draw the line. |

6 . Creativity is the ability to generate novel,useful ideas and innovation is the successful application of those ideas.With this in mind,it is easy to think that technology has made us more creative:the digital revolution(改革）has clearly produced a large number of innovative products and services.
However,it would be naive(幼稚的）to imply that these activities are truly indicative of creativity,even if quantity does eventually lead to quality.For instance,the probability of taking a great photograph does increase when there are millions of Instagram pictures taken every day,and when 500 million tweets are generated(严生）daily,it is highly probable that one or two will be funny.
Yet,much of the content people generate is unimportant and unoriginal.Before the Internet it would have stayed in the minds of their authors,but our thoughts can now be broadcasted to the. world as if they were worthy creations.The only thing that appears to have increased,rather greatly,is people's self-perceived(自认为的）creativity.From the use of emoji(表情符号）instead of words,to the use of pre-determined functions to express our views-liking,sharing and disliking,these new forms human interaction promote efficient-but lazy-behaviors so that we can devote more time to consuming more content.
Although user-generated content has been growing rapidly in the past decade,much of it is noise and the result is that valuable and trustworthy information is now harder to find.In an age of information glut(过剩），everything is freely available but knowledge is hard to gain.This paradox highlights the importance of the"less is more"philosophy of life.
Curiosity evolved to make sense of the world and help us master our environments.Our ancestors must have benefited from taking on as much information from their surroundings as they could paying attention to everything and turning into the learning machine.Yet in an age of information glut,the curious mind is forced to ignore as much of the available data as it can,in order to consume only what is valuable.
1. Why are the examples of great pictures and funny tweets mentioned in Paragraph 2?| A．To show quantity will lead to quality. |
| B．To explain creativity is something impressive. |
| C．To show technology hasn't made us more creative. |
| D．To explain innovative products come from creativity. |
| A．They are worthy creations. |
| B．They kill people's creativity actually. |
| C．They prevent effective communication. |
| D．They help people consume more useful content. |
| A．There' re more resources for knowledge but few people are willing to use them. |
| B．Too much information has generated material wealth but not spiritual wealth. |
| C．We live in an age of information explosion but we find it difficult to get knowledge. |
| D．Many people stick to the"less is more"philosophy with large amounts of information at hand. |
| A．Much of it is original information about the real world: |
| B．It is the fruit of our ancestors' mastering our environments.. |
| C．It gives the public quick and easy access to the required information. |
| D．It presents us with the challenge of telling valuable information from worthless content. |
7 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

| A．I wasn't alone any longer. |
| B．I enjoyed reading stories aloud. |
| C．I was invited to play with another kid. |
| D．I loved the colorful photographs in the books. |
| E．Another habit I formed early was being outdoors. |
| F．Thus, I began my lifelong interest in making things. |
| G．My older brother couldn’t be bothered to play with me. |
9 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

10 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
