The emperor penguin is the tallest and heaviest of all living penguin species and lives in Antarctica. The male and female are similar in size, reaching 122 cm in height and weighing anywhere from 22 to 45 kg. The back and head are black, contrasting sharply with the pale-yellow breast and bright-yellow ears. Like all penguins, it is flightless, with a streamlined body and their wings stiffen and flatten into flippers(鳍状肢) for a marine habitat.
Its diet consists primarily of fish, but can also include animals with hard shells. In hunting, the species can remain underwater up to 18 minutes, diving to a depth of 535 m. Its unusually structured hemoglobin(血红蛋白)allows it to function at low oxygen levels.
The emperor penguin is perhaps best known for the journeys adults make each year in order to mate and to feed their babies. The only penguin species that breeds(繁殖) during the Antarctic winter, it goes on a long journey of 50-120 km over the ice to breeding areas which may include thousands of individuals. The female lays a single egg, which is incubated(孵化)by the male while the female returns to the sea to feed; parents take turns searching for food at sea and caring for their chick. They both care for the chick until it is able to enter the water to find food on its own. During the process of incubation, the male can lose up to 1/3 to 1/2 of his body weight. One of the coolest things about the male is that if the chick comes out its egg before the female returns, the male can actually produce a special liquid to feed the chick. He can only do this for a short time. If the female doesn’t return, he must leave the chick to go on with his own life. The emperor penguin can typically live for 20 years in the wild, although observations suggest that some individual may live to 50 years of age.
1.We can learn from paragraph 1 that ____.
A. the emperor penguin is the world’s largest kind of penguin
B. the emperor penguin has pale-yellow ears
C. the male and female emperor penguins are of different sizes
D. the emperor penguin lives in the most northern area on the Earth
2.The emperor penguin can stay underwater for a long time mainly because of its ____.
A. strong wings B. streamlined body C. structured hemoglobin D. special diet
3.The emperor penguin differs from other penguin species in that ____.
A. it gives birth in the Antarctic winter B. it feeds mainly on fish
C. the male won’t search for food on his own D. it can only live for a short time
4.According to the passage, ____.
A. the egg of the emperor penguin is mainly incubated by the female
B. many emperor penguins will stay together to breed
C. the male emperor penguin will give up his own life to feed the chick
D. the female emperor penguin will leave the chick forever once it lays an egg

With the development of society, it is common that many people are rushing all the way and all day, tired and sub-healthy.1. She described all the things she had to do--- one was to make her bed ---from the moment she woke up until she flew out of the door for work. I suggested she experiment by not making her bed for two weeks. She was shocked, probably thinking I’d been brought up by wolves in a forest.2.
Two weeks later she went into my office merrily. She had left her bed unmade for the first time in 42 years--- and nothing bad had happened. “And you know what?” she said. “I don’t dry my dishes anymore, either.”
3. One was discovering that she had choices in her life that she had never seen before. The other was giving herself permission to be less than perfect. This story shows an important principle about managing time: no one can do it all. Each of us has to make choices and accept trade-offs(利弊权衡). The problem is that many people choose in ways that put themselves and their health last. They take better care of their houses and cars than they do of themselves.4.
So what is the solution? There’s an easy way. Decide what you want in your life, and put that first. On a daily basis, that should include regular meals, enough sleep and time with your family. Exercise, leisure, friendships and hobbies should also be regular aspects of life. 5. The choice is yours: whatever makes you feel good about yourself and your life. Take a nap. Take a walk. Take time to play the piano. Stop bringing your briefcase home from the office. Stop keeping your house as clean as your mother kept hers. Fill more of your time with want-to-dos instead of have-to-dos.
A. Most people do not take time to relax themselves.
B. The point is to do something for yourself every day.
C. This woman had made two major breakthroughs.
D. A patient came to see me about the stress in her life.
E. Above all, you needn’t do anything for yourself regularly
F.They put everyone else’s needs ahead of their own.
G. However, she went along with my idea.

Pierre is a 25-year-old penguin at the California Academy of Sciences. Due to his old age, he was going bald, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool.
Unlike marine mammals, which have a layer of fat to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.
"He was cold; he would shake," said Pam Schaller, a senior biologist. Schaller first tried a heat lamp to keep Pierre warm. Then she got another idea: if wetsuits keep humans warm in the cold Pacific, why not make one for Pierre?
Schaller designed the suit, which covered Pierre’s body and had small openings for his flippers.
“I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely suitable,” she said.
One concern was that the other penguins would reject Pierre in his new suit, but in fact, they accepted his new look. He swam freely and got along with others well, although he was the only penguin with a black stomach.
Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers, but “certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable”.
Pierre will take off his suit after his new feathers grow back.
1.Pierre felt too cold to swim in the pool because of _____.
A. not having a layer of blubber
B. having few feathers due to old age
C. having no wetsuit
D. others penguins rejecting him
2.The idea of making a wetsuit for Pierre came from _____.
A. total invention
B. waterproof feathers
C. the use of wetsuit on humans
D. the use of heat lamp
3.Schaller followed Pierre in order to see _____.
A. whether other penguins would reject him
B. if anywhere of wetsuit needed to be cut and refit
C. if the wetsuit kept warm
D. whether the wetsuit would keep the feathers from recovering
4.The best title of the passage is _____.
A. Wetsuit for An Old Penguin
B. Old Penguin Getting Bald
C. Unwilling to Swim
D. Strange Look of PierreB

Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.
Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.
65 to 70 percent of the human body is water. Water is important in several different ways.

“Data is the new oil.” Like the sticky black thing, all those Is and 0s are of little use until they are processed into something more valuable. That something is you.
Five of the world’s ten most valuable companies are built on a foundation of tying data to human beings. Google and Facebook want to find out as much as possible about their users’ interests, activities, friends and family. Amazon has a detailed history of consumer behavior. Tencent and Alibaba are the digital wallets for hundreds of millions of Chinese; both know enough about consumers to provide widely used credit scores. Those with a good Zhima credit score, provided by Alibaba, enjoy discounts. Those without receive few offers. In other words, data are used to decide what sort of access people have to services.
That data are valuable is increasingly well-understood by individuals, too, especially because personal information is so often leaked(泄露)or stolen. The list of companies that have suffered some sort of data leak in 2018 alone reads like a roll call of household names: Facebook, Google, British Airways and so on. Such events have caused a switch in the public understanding of data collection. People have started to take notice of all the data they are giving away.
Yet few people have changed their online behavior or exercised what few digital rights they possess. Partly this is because managing your own data is time-consuming and complex. But it is more because of a misunderstanding of what is at risk. “Data” is an abstract concept. Far more solid is the idea of identity. It is only when “data” is understood to mean “people” that individuals will demand responsibility from those who seek to know them.
The fossils of past actions fuel future economic and social outcomes. Privacy rules and data-protection regulations are extremely important in protecting the rights of individuals. But the first step towards ensuring the fairness of the new information age is to understand that it is not data that are valuable. It is you.
1.The example of Zhima credit scores is mentioned to show __________.
A.data help companies target their services
B.credit scores change people’s way of life
C.Alibaba gains popularity among customers
D.people prefer to be offered discounts
2.What has caused a change in the public understanding of data collection?
A.The development of companies. B.The history of consumption.
C.Cases of data leak and theft. D.Lists of household names.
3.People don’t protect their data well mainly because __________.
A.they find it time-consuming and complex
B.they are not fully aware of its importance
C.they have no access to their personal data
D.they are afraid of taking responsibility
4.What is the author’s purpose in writing the text?
A.To defend companies’ use of data.
B.To show the economic value of data.
C.To call for more regulations to protect data.
D.To advocate a new way of thinking about data.

It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. Everybody knows that the nicest men become monsters behind the wheel. It is very well, again, to have a tiger in the tank, but to have one in the driver’s seat is another matter altogether. You might tolerate the odd road-hog, the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a “Be Kind to Other Drivers” campaign, otherwise it may get completely out of control.
Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered drivers to resist the temptation to revenge when subjected to uncivilized behavior. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently to allow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the road would be clear anyway; or the man who waves a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to. It always amazes me that the highways are not covered with the dead bodies of these grannies.
A veteran (资深的) driver, whose manners are faultless, told me it would help if motorists learnt to filter correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone master the subtler aspects of boatmanship. Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.
1.According to this passage, troubles on the road are primarily caused by ________.
A. people’s attitude towards the road-hog
B. the rhythm of modern life
C. the behavior of the driver
D. traffic conditions
2.The sentence “You might tolerate the odd road-hog... the rule.” (Para. 1) implies that ________.
A our society is unjust towards well-mannered motorists
B. rude drivers can be met only occasionally
C. the well-mannered motorist cannot tolerate the road-hog
D. nowadays impolite drivers make up the majority of motorists
3.In the writer’s opinion, which is “misplaced politeness”?
A. Revenge when subjected to uncivilized behavior.
B. Encouraging old ladies to cross the road as long as they want to.
C. A wave of acknowledgement in response to an act of politeness.
D. Waving a child across a zebra crossing.
4.In the writer’s opinion, ________.
A. strict traffic regulations are badly needed
B. drivers should apply road politeness properly
C. rude drivers should be punished
D. drivers should avoid traffic jams

The city-state of Dubai that is home to the world’s tallest building is fast improving its reputation as the city of the future. On May 22, Dubai officials added to their list of futuristic accomplishments with the introduction of the world’s first robot police officer.
Nicknamed Robocop after the 1987 action movie,the 1.7-meter tall humanoid (类人的) robot was introduced at the 4th annual Gulf Information Security Expo and Conference. First introduced in 2011 as REEM by Barcelona-based PAL Robotics, the robot was built to entertain guests at conferences and serve as an information booth at public places. However, the forward-thinking officials of the Dubai police force saw another potential application and partnered with the Spanish company to build a version that would help improve public safety.
Locals and visitors can get help from Lieutenant Robocop which is currently on duty at the Dubai Mall, using the touchscreen on its chest. Armed with technology from Google and IBM’s supercomputer Watson,the “policeman” can provide visitors with directions and other information regarding the mall in one of six languages, including Arabic and English and also accept payment for any fines, like parking tickets. It can also detect criminals with an 80 percent accuracy from 100-feet away and send the information real-time to command center through its camera eyes. While Robocop cannot physically protect people in trouble, an SOS button on its touchscreen can connect them to a human member of the Dubai police force instantly. When not assisting people or seeking out lawbreakers, Robocop brings smiles to people’s faces by posing for selfies or showering them with compliments.
Once the robot officer has been thoroughly tested, the Smart Services Department at Dubai Police plans to “hire” more Robocops to patrol (巡逻) other public areas and also act as receptionists at police stations.
1.Where does Robocop get its name?
A. From a movie. B. At a conference.
C. From a building. D. From Dubai officials.
2.What was the original purpose of Robocop?
A. To be officials’ partner.
B. To help guests in a company.
C. To serve in Dubai police stations.
D. To offer entertainment and information.
3.How can people communicate with Robocop?
A. By touching its screen. B. By paying some money.
C. By asking the mall for permission. D. By getting directions from a policeman.
4.How does Robocop react to lawbreaking?
A. It fines the lawbreakers.
B. It physically protects the victim.
C. It reports the situation to a policeman.
D. It sends an SOS message to the company.
