When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on Earth. We have polluted the deepest oceans with plastic trash, 1.
German scientists have recently found microplastics in Arctic snow. 2.Sadly, the scientists found 1,800 pieces of microplastic per liter of snow.
How is plastic pollution reaching the Arctic? According to scientists. "It's apparent that the majority of the microplastics in the snow comes from the air." They fall off plastic objects and are moved by the wind, just like dust. 3.Finding these plastics in Arctic snow means that we may breathe them in. An even higher amount of microplastic was found in the snow around cities.
The high concentrations found in snow samples suggest microplastics, which contain rubber or chemicals used in synthetic fabrics(混合纤维), may cause significant air pollution.
4.Scientists cannot answer this question for now, according to the world Health Organization. We do know that our bodies cannot take in "large" pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time. What's more, earlier studies have shown that microplastics may contribute to lung cancer risk, heightening the need to further assess the risks of taking them in, the study said.
Microplastics have also been found in rivers and oceans around the world. Previous research has found that they flow over long distances and into our oceans, damaging ecosystems along the way.5.The waste water then flows into rivers and out to sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.
A.Are they bad for us?
B.and now it's the Arctic's turn.
C.so we should take action to protect the world.
D.They mix with ice in the air and fall to the ground as snow.
E.Microplastics are pieces of plastic smaller than 5 millimeters.
F.They start in our water when we wash clothes with plastic fibers.
G.Is plastic pollution doing great damage to our global economy?

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer(模糊的) than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.
When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.
The image you create for yourself has rather strange proportions(部分); certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.
Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.
If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes (中风)which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.
1.According to the passage the “felt” image________the mirror image.
A.is precisely the same as B.is as clear as
C.often differens from D.is always much smaller than
2.Which the following staterants is NOT true?
A.The felt Image is much more important because it helps you locate new feelings.
B.When you are in bed with your eyes closed, it is not easy to imagine your image.
C.When you move, the “felt” image of yourself starts to become clearer.
D.The “felt” image is not so important as the mirror image.
3.If a man loses the ability to recognize his right side,________.
A.he can’t locate the doctor’s touch on his left side
B.he can’t locate the doctor’s touch on his right side
C.he loses his sense of touch on the left side
D.he loses feeling on both sides
4.What is this passage mainly about?
A.Stroke victims’ “felt” images B.Stroke victims’ mirror images.
C.The importance of “felt” images D.The importance of mirror images.

When you think of the future,you imagine having some sort of robot friend in your life.Musio,a new robot unveiled recently,is something like that.
Musio is an artificial intelligence software that runs on Google's Android mobile OS,and is packaged in the form of a round little robot with pointy ears.It doesn't move around,but it has a digital screen for its eyes and heart that are used to express the robot's emotions.It also comes with a remote pointer device,called Sophy,which is used to detect objects that trigger different interactions with Musio.
The robot was created by AKA,a company specializing in machine learning and natural language processing.It's designed to interact with its users with a voice interface,much like you'd use Siri.But Musio's creators,Wilmington, Delaware-based AKA Study,stress that this is a much different experience than using Siri—Musio can have interactive conversations and remember information about its users,sort of like a little person.Musio can do all sorts of things like controlling home automation and it has a number of integrated sensors.The robot is also programmable and it is able to speak naturally.It is designed to share its emotions via faces on its LCD screen.There are three versions of Musio that vary on hardware.The Simple version has a 1.2GHz dual core processor,1800 mAh battery, 16GB storage and isn't internet connected.It can only recall the last five conversations it has.
Beyond running on the open source Android platform,Musio is also Arduino compatible.The Arduino platform is an open source electronics platform built to be easy to program.Its purpose is to take different inputs through a suite of sensors and then relay commands to lights,motors,or actuators as a result.Musio is also compatible with the Zigbee wireless standard used by a range of smart home devices,so it's possible that developers could intertwine the robot with other appliances and turn it into a sort of voice-activated smart home hub with a personality.
And there are several educational accessories that come with Musio,such as flash cards and a fold-out accordion board book.Using Sophy,the pointer,Musio can interact with these objects thanks to a Bluetooth low-energy connection and a special code implanted in the printed materials.
1.What is Musio?
A. A digital e-book reader. B. A language learning software.
C. An artificial intelligence robot. D. A voice-controlled website.
2.How is Musio different from Siri?
A. It can hear and understand what its user speaks.
B. It connects a lot of programs.
C. It will give a variety of commands.
D. It can exchange verbal information with its users interactively.
3.Why could developers intertwine Musio with other appliances?
A. Because it could run on the open source Android platform.
B. Because it has a strong compatibility.
C. Because it takes different inputs through a suite of sensors.
D. Because it relays commands to lights,motors,or actuators.
4.What does the underlined word “accessories” in Paragraph 5 mean?
A. Attachments. B. Sensors.
C. Pointers. D. Platforms.

I live in the land of Disney, Hollywood and year - round sun.You may think People , such an attractive, fun - filled place are happier than others.If so you have some mistaken ideas about the nature of happiness.
Many intelligent people still think fun equals happiness.The truth is that fun and happiness have little or nothing in common.Fun is what we experience during an act.Happiness is what we experience after an act.It is a deep, long-lasting emotion.
Going to an amusement park or a ball game, watching a movie or television are fun activities that help us relax, temporally forget our problems and maybe even laugh.But they do not bring happiness, because their positive effects end when the fun ends.
I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun.They have constant access to exciting parties, fancy cars, expensive homes, everything that spells "happiness" But in memoir(回忆录) after memoir, they expose Ac unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages and loneliness.
Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying.If he is honest, he will tell you that he is afraid of making a commitment.For commitment is in fact quite painful.The single life is filled with fun, adventure and excitement.Man-iage has such moments, but they are not its most distinguishing features.
Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness.They can dine out whenever they want and sleep as late as they want.Couples with babies are lucky to get a whole night' s sleep.I don't know any parent who would choose the word fun to describe raising children.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to.It liberates time: now we can devote more hours to activities that can truly increase our happiness.It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless.And it frees us from envy: we now understand that all those rich and famous people we were so sure are happy because they are always having so much fun actually may not be happy at all.
1.What is the passage mainly about?
A.Fun and happiness. | B.Success and satisfaction. |
C.Marriage and commitment. | D.Entertainment and responsibility. |
2.The author probably agrees that ____.
A.fun creates long - lasting satisfaction |
B.long - standing fun may lead to happiness |
C.fun is short-lived while happiness is long-lasting |
D.fun provides enjoyment while pain leads to happiness |
3.What does the author think of marriage?
A.It ends in pain. | B.It means commitment. |
C.It affords greater fun. | D.It leads to raising children. |
4.If one gets the real meaning of happiness, he ____.
A.will start a business B won' t place too much value on money

What comes into your mind when you think about robots? Do you imagine armies of evil metal monsters planning to take over the world? Or, perhaps of mechanical men who have been created as guards or soldiers by a mad genius? Or maybe you think of man- like robots who act, think, and look like human beings. In fact robots like these have more to do with science fiction films than with real life. In the real world robots are machines that do jobs which otherwise have to be done by people. Robots either operate by themselves or under the control of a person.
In a car factory, for example, robot machinery can put together and paint car bodies. On the sea bed remotecontrolled(遥控)underwater machines with mechanical arms can perform tasks too difficult for divers. Robot spacecraft can explore the solar system and send back information about planets and stars.
Many robots have computer brains. Some robots are fitted with cameras , sensors, and microphones which enable them to see, to feel, and to hear. And some robots can even produce electronic speech.
All this does not mean that a robot can think and behave like a human being. Present day robots have to be programmed with a good deal of information before they can carry out even simple tasks.
44.Robots in real life________.
A. can behave like human beings B. have the ability to control the world
C. can think by themselves D. can help us with a lot of work
45.According to this article, which of the following is not true about robots in the real world?
A. Some robots are as creative as artists. B. Some robots can help manufacture cars.
C. Some robots can see and hear. D. Some robots can explore outer space.
46.Robots can perform many tasks for man because________.
A. they have intelligence B. they are supplied with computer programs
C. they can imitate human beings D. they have the ability to learn new things
47.The robots in science fiction films and those in real life differ mainly in________.

Imagine that a close friend ignores you when you arrive at his party. 1. But if you think about the situation differently, you would calm down. Using a particular emotion management strategy called reappraisal, which involves viewing an upsetting event in a positive light, is often effective in contributing to positive outcomes.
2. The research showed that if people believed feelings were malleable (可塑造的), they used reappraisal more frequently, and in return they had greater emotional health and life satisfaction.
University of Toronto researcher Brett Ford and her colleagues did another study. 3. The researchers found that the youths who believed emotions were controllable used reappraisal more and were less depressed than those who didn’t.
Does accepting our feelings impact our well-being? 4. In one research, the researchers stressed out participants by requiring them to give an impromptu (即兴的) talk. In another research, people kept daily diaries about how they handled stressors (紧张性刺激). In both cases participants who accepted their feelings experienced less negative emotions than people who judged their feelings.
“However, while emotions may be changed with efforts, that doesn’t mean they’re completely controllable,” says Eric Smith of Stanford University, “we shouldn’t expect to completely avoid or immediately remove certain of feelings. 5.”
A.It found a similar pattern.
B.You would be angry or upset, right?
C.We have beliefs about our emotions.
D.According to Ford and her colleagues, it does.
E.But we can learn to reduce them in hard times.
F.They were also less depressed and more satisfied with life.
G.Now, new research suggests our beliefs about our feelings affect us greatly.

The Arctic is not a safe place to be by any stretch of the imagination. Essentially a vast, floating block of ice, with only a small area of land, the landscape can be almost totally different from year to year. Even the most experienced explorers are lucky to return with all their fingers and toes, not to mention their lives.
Into this extreme environment stepped Nabil Al Busaidi. In fact, he didn’t just step—he stepped and skied his way across 650km, pulling 50kg of equipment. He also carried the flag of the Sultanate of Oman, which he held in the air at the North Pole, becoming the first Arab to achieve this impressive feat (壮举).
On the way to the North Pole, Nabil was driven by the reward of success and the pain at the thought of failure. “Through the 20-whatever days , every minute there was a different thing that kept me going, either the fear of failure, the fear of dying or the reward of finishing and getting somewhere warm. ”
The ever-present cold, averaging around -40℃ but dropping as low as a recorded -81℃, is his overriding (首要的) memory of the experience. As an Omani, Nabil had an additional 20℃ drop in temperature to get used to, compared to his British teammates. Apart from the extreme cold, polar bears were a common feature of the journey, and Nabil and the team had their fair share of bear encounters. “Polar bears are dangerous, but they are not that threatening because they don’t intend to harm humans. They’re usually either curious or just don’t care. We saw five bears, and none were aggressive,” said Nabil.
One final problem Nabil faced was the stress put on team relations by the severity of the conditions, especially during the first three stages of the journey. However, during the fourth and final leg, the team worked so well together that they travelled 130km in only two and a half days.
1.What does Paragraph 1 show?
A. Nabil’s hard-won success. B. The value of Arctic exploration.
C. Nabil’s good luck. D. The change of the Arctic.
2.Which is the problem Nabil faced on his journey?
A. Gradually rising sea level. B. Frequent polar bear attacks.
C. Constantly changing climate. D. The heavy psychological burden.
3.What can we know about Nabil?
A. He had gone on an Arctic journey before.
B. He explored the Arctic with pretty light packs.
C. He finished the exploration of the Arctic all alone.
D. He suffered more from extreme cold than his teammates.
4.What is the passage mainly about?
A. Life in the Arctic.
B. Climate of the Arctic.
C. The first Arab to step into the Arctic.
D. Achievements scientists made in the Arctic.

高三英语单项填空简单题查看答案及解析
Imagine you’ve finally landed a job of your dreams in another city. It’s everything you’d hoped for, but there’s only one problem — housing costs in the area are so high that you’re forced to live in a parking lot.
While this sounds like an impossible situation, this predicament is a reality for one man.
Brandon, 25, is a software engineer for Google at its San Francisco, California campus.
“I realized I was paying too large an amount of money for the apartment I was staying in, and I was almost never home,” he told Business Insider. “It’s really hard to justify throwing that money away. You’re not putting money into anything and you are not building it up for a future.”
Since scoring his job in May 2015 following a successful internship, he’s been living in a truck on a parking lot a short distance from his workplace.
The tech worker makes up for the lack of facilities by eating, using the bathroom and showering at work, also charging his phone and computer there.
San Francisco is home to the most expensive rental market in the US, with the average rental for a one-bedroom apartment coming to $3,590 (24,900 yuan) a month, according to property site Zumper.
And while some may not be able to handle giving up life’s luxuries just to put aside some cash, Brandon estimates that he’s saved almost $28,000 since he moved in just over 18 months ago.
“Not only do I get to invest all of that redirected rent money, but I get to invest all the money I’m not spending on furniture, facilities and buying food,” Brandon wrote on his blog.
1.Which of the following can replace the underlined word “predicament” in Paragraph 2?
A. possibility B. disappointment C. dilemma D. mess
2.Why does Brandon prefer to live in a truck on a parking lot?
A. Because he has no time to go back to an apartment.
B. Because the rent is too high and he thinks it isn’t worthwhile
C. Because his workplace provides him with what he needs
D. Because he wants to save money for an apartment of his own.
3.What does Brandon think of his choice?
A. Difficult. B. Embarrassing. C. Painful. D. Wise.

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big.
All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers—plastic products of all kinds.
The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.
In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full,lessening their desire to eat or drink.
The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.
Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.
In August,2009,a team from the University of California,San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.
1.What do we know about the Great Pacific Ocean Garbage Patch?
A. It is made up of various kinds of plastic products.
B. It is a solid mass of floating waste materials.
C. It lies l60 000 kilometers east of California.
D. It is described as a kind of oceanic desert.
2.Why do people pay attention to the Great Pacific Ocean Garbage Patch?
A. Because it may prevent the flow of ocean water.
B. Because the polluted plastic articles will move up the food chain.
C. Because it may be from an island in the pacific.
D. Because ships may be trapped in the floating waste.
3.Which column can you find the passage on a newspaper?
A. Sports and entertainment. B. Media and culture.
C. Environment and society. D. Science and technology.
4.The purpose of writing this passage is to____________.
A. warn people of the danger to travel in the pacific
B. analyze what caused the waste patch in the pacific
C. give advice on how to recycle waste in the ocean
D. introduce the Great Pacific Ocean Garbage Patch
