Making employees feel happy and healthy at work is good for many businesses. But it isn’t always an easy thing. A study suggests that only 33% of the U. S. employees consider themselves fully engaged （投身于）in work, while 16% are greatly disengaged, and 51% are just showing up.

But there is an exception. When it comes to employee engagement, it seems that employees in small companies are doing better. According to the same research, the largest U. S. companies are at the lowest levels of engagement, while companies with fewer than 25 employees are at the highest. And in one recent report, 75% of small business workers surveyed said they were “very” or “extremely” satisfied with their role as a small company employee.

Unlike big companies, small companies are often short of resources but the employees can get more surprises there. Small companies offer excellent career opportunities to their employees. The bosses often know their staff very well and understand their personal needs. Employees of small companies are more likely to receive free meals, paid leave, and they can even bring their pets to work.

But of course ? there are many other draws in small businesses. One of the top draws is flexible scheduling (弹性工时). Another is being able to really see the fruits of one's labor. Besides, non-cash award is also a big draw. This could be something small that reflects employees’ interests and lifestyles.

While a parental leave might lead to some financial problems, small companies may do something to improve it. “It may be impossible for a five-person team to be reduced to four for six months,” writes Camillia Velasquez, head of HR management platform, Justworks. “But it could be possible to allow new parents to take on reduced hours in a work-from-home environment. ” This kind of method has been realized in some small companies.

1.What can we know about employees in big and small companies?

A. Employees can develop better in small companies.

B. Employees can earn more money in small companies.

C. Employees in big companies are hard to be satisfied.

D. Employees in small companies are more engaged in work.

2.What can we learn from Paragraph 3?

A. Working for small companies has many benefits.

B. All the employers in small companies know every staff member very well.

C. Staff in small companies may face many challenges.

D. Staff in big companies have more material benefits.

3.Compared with big companies, what is the advantage of small companies?

A. Employers in small companies have more choices.

B. Small companies have more attractions to employees.

C. Employees of small companies may have higher salaries.

D. Employees of small companies have fixed working time.

4.What can be most probably inferred from the passage?

A. Small companies may have more employees with much happiness.

B. Big companies should learn from some small companies.

C. Employees should have their own hobbies and lifestyles.

D. Employers should pay more attention to the staff’s needs.

Rivers are earthly arteries(要道) for the nutrients, deposits and freshwater that sustain healthy, diverse ecosystems. Their influence extends in multiple dimensions—not only along their length but below­ground to aquifers(蓄水层) and periodically into nearby floodplains.

They also provide vital services for people by fertilizing agricultural land and feeding key fisheries and by acting as transportation corridors. But in efforts to ease ship passage, protect communities from flooding, and draw off water for drinking and irrigation, humans have increasingly constrained and broken these crucial water ways. “We try to control rivers as much as possible,” says Gunther Grill, a hydrologist at McGill University.

In new research published in May in Nature, Grill and his colleagues analyzed the barriers to 12 million total kilometers of rivers around the world. The team developed an index(指数) that evaluates six aspects of connectivity—from physical fragmentation (by dams, for example) to flow regulation (by dams or levees) to water consumption—along a river’s various dimension. Rivers whose indexes meet a certain threshold(临界值) for being largely able to follow their natural patterns were considered free­flowing.

The researchers found that among rivers longer than 1,000 kilometers (which tend to be some of those most important to human activities), only 37 percent are not blocked along their entire lengths. Most of them are in areas with a minimal human presence, including the Amazon and Congo basins and the Arctic. On the contrary, most rivers shorter than 100 kilometers appeared to flow freely—but the data on them are less comprehensive, and some barriers might have been missed. Only 23 percent of the subset of the longest rivers that connect to the ocean are uninterrupted. For the rest, human infrastructure is starving estuaries(河口) and deltas (such as the Mississippi Delta) of key nutrients. The world's estimated 2.8 million dams are the main cause, controlling water flow and trapping deposits.

The new research could be used to better understand how proposed dams, levees and other such projects might impact river connectivity, as well as where to remove these fixtures to best restore natural flow. It could also help inform our approach to rivers as the climate changes, says Anne Jefferson, a hydrologist at Kent State University, who was not involved in the work. Existing infrastructure, she says, “has essentially been built to a past climate that we are not in anymore and are increasingly moving away from.”

1.According to the passage, which of the following is NOT a function of rivers?

A.Easing ship passage. B.Fertilizing agricultural land.

C.Transporting people or goods. D.Sustaining healthy ecosystems.

2.What does the underlined word “constrained” in Paragraph 2 most probably mean?

A.Exhausted. B.Restricted.

C.Consumed. D.Expanded.

3.The underlined word “them” in Paragraph 4 refers to “________”．

A.earthly arteries B.human activities

C.entire lengths D.unblocked rivers

4.What does Anne Jefferson mean by the underlined sentence in the last paragraph?

A.Existing infrastructure has been perfectly built.

B.Existing infrastructure doesn't depend on the past climate.

C.Existing infrastructure determines the future climate.

D.Existing infrastructure doesn’t fit the changing climate.

Here are my favorite tips for staying physically, mentally and emotionally healthy during the winter months. Vacation not included. 1.

Raise your vitamin D levels naturally (without pills or sunlight). We’ve all heard about the marvels of vitamin D: heart health, skin health, immune health, mental health… But you don’t need to take pills or risk skin cancer to get high vitamin D levels. The big secret is that vitamin D levels are associated with healthy lifestyle changes. For example, if you lose just 5 percent or more of your body weight, your vitamin D blood levels will shoot up. Vitamin D likes to stay in fatty tissue, so when you lose fat, the vitamin D levels in your blood go up. 2.. And when you eat your wild salmon, bake it rather than fry it. Other good food sources are trout, mushrooms and egg yolks, and my favorite, plain Greek yogurt.

3. Winter can be a tough time for many of us. All that darkness can take its toll on our mental health. The winter months can be very isolating for many people. My suggestion is that you and a close friend sign up for yoga, cooking or sewing class. 4.

Eat more plants—the ones that are sources of omega-3 fatty acids. According to the famous Harvard Nurses’ Health Study, there was no relation between depression and intake of omega-3 fatty acids from fish, 5.. And again, the wintertime is when many people have a higher risk of depression.

A.Take a class with a friends

B.but they did find a reduced risk of depression in those with moderate intake of plant-based omega-3 fatty acids

C.Isolate yourself during wintertime

D.The following three simple suggestions are things that anyone can do easily and inexpensively to stave off the winter blues and sniffles (鼻塞).

E.Not only do these kinds of classes improve your mental and physical fitness, but they help to fill that social craving (渴望) that we have as human beings, too

F.and there was no evidence to show the benefit of plants

G.Other ways to increase vitamin D naturally are to lower your cholesterol (胆固醇) exercise and eat more fatty fish, such as wild salmon

A study into character, intelligence and usefulness shows dogs are better pets than cats—but only by a whisker.

Staff at New Scientist magazine first listed the areas where cats fared better. These included having bigger brains—compared to their body size. Cats’brains also contain 1.4 million more cells, devoted to complex functions such as memory and attention, than dogs. Cats’second point was given for being more popular, with 204 million living in the top ten cat-owning nations compared to 173 million dogs in the ten countries where dogs are favored. Cats also get more attention from humans, with purrs （呼噜声）and miaows easily to be noticed. Although dogs can vary their barks, they cannot match the attention-seeking of cats. It is a similar story when it comes to senses. Cats can see in lower light than dogs and have a far wider hearing range and a sharper sense of smell. They are also said to be’greener’pets because their smaller appetites mean less area of land required to farm their food.

But in the other six categories examined—many of which related to getting on with humans dogs had the edge.

Dogs have a longer shared history with humans, maybe as long as 135,000 years. Cats are relative newcomers to our homes. Similarly, dogs have a greater ability to bond with their masters. Even four-month-old puppies choose a human companion over another dog. Dogs scored a third point for their better powers of understanding and following human gestures. One study found that a dog called Rico had mastered the meaning of more than 200 words. The ability to perform roles such as being a guide dog for the blind meant dogs were rated better than cats when it came to their problem-solving abilities. And they are easier to train.

With the scores tied at five-all, the deciding point fell on usefulness—with dogs coming out on top.

Dogs, studies show, help cut human stress, while taking them for walks keeps their owners fit and helps them meet new people. New Scientist says: “Dogs can hunt and guard. They can sniff out drugs and bombs; they guide blind and deaf people, find someone buried in ruins, and possibly even predict earthquakes.”

And in a conclusion certain to set off argument, it adds: “Cats are good if you have rodents （啮齿类动物）.”

1.Which of the following is not cats’ advantage?

A．Better at grasping their owners’ instructions.

B．Having relatively larger brains.

C．Affecting the environment less.

D．More likely to drawing attention.

2.The underlined phrase “by a whisker”（paragraph 1）probably means “        ”.

A．quite considerably             B．just a little bit

C．most significantly                 D．in some aspects

3.We can learn the fact from the passage that          .

A．Dogs are far from satisfactory in terms of their ability to catch rodents

B．Dogs can better help people who have problems with their sight and hearing

C．Comparatively speaking, cats have a better interaction with humans

D．Dogs beat cats when it comes to their senses of sight, heating and smell

4.Which would be the best title for the passage?

A．Cats beat Dogs                      B．Fight like Cat and Dog

C．Cats versus Dogs                D．Cats away, Dogs Play

Before Douglas Engelbart, computers were as big as rooms and used mostly for handling numbers. But in the late ‘60s’at the Stanford Research Institute, Engelbart invented almost everything your personal computer has today: a mouse, hypertext, screen sharing and more. In 1968 he made real-time edits to documents nearly 40 years before Google Docs hit screens; video chatted with friends long before Skype’s 2003 arrival; and resized windows years before Microsoft entered the field in 1975. Engelbart was adding graphics (图形), hyperlinking and sharing screens — all before the birth of the World Wide Web. “The digital revolution is far more significant than the invention of writing or even of printing,” said Engelbart, and as it turns out, he held all the right cards.

If he’d been British，Engelbart would have been knighted (授爵), but the Portland, Oregon, native instead lived out the rest of his years as an unsung hero, trying to fry even bigger fish in Silicon Valley. His blueprint of the Internet was radically different from today’s profit- driven, streamlined version. Engelbart imagined an information system built on the backbones of cooperation and education, all meant to enhance the collective human mind. He wanted a computerized network of real-time, human-wide cooperation, with the open-source spirit of Wikipedia and the purposefulness of Change.org.

By the late 70s and early ‘80s’ Engelbart and his ideas were cast aside in favor of Apple Macintosh and Microsoft Windows, along with their profit-generating vision for personal computing, and a user-friendly approach to the Internet. Engelbart’s team of researchers abandoned him, and he had a lesser position at a company called Tymshare while still battling with his pie-in-the-sky visions of a better world. Even worse, when Engelbart’s mouse invention gained widespread use years later, he never gained the profits — it had been licensed to Apple for around $40,000, Engelbart revealed.

And if Engelbart had won? “Hard to say,” says Jefferson Bailey of the Internet Archive in San Francisco. The Web was bound to grow in ways its founders never intended, he says. He notes his belief that the same spirit of knowledge-sharing and cooperation Engelbart tirelessly pushed for will one day become part of our fast-evolving Internet, even if a commercial layer clouds the original vision. But even so，fame is difficult to achieve; it often ridicules great thinkers like Galileo or Tesla, only to meet them decades after death. Granted, Engelbart was eventually allowed into the National Inventors Hall of Fame, in 1988, and into the Pioneers Circle in the Internet Hall of Fame after his death, but the heart of his dream has yet to be realized.

1.The expression “his pie-in-the-sky visions of a better world” in Para. 3 refers to______________.

A.the function of computer data processing

B.a real-time video chat on the Internet

C.a user-friendly approach to the Internet

D.an Internet of knowledge-sharing and cooperation

2.Most probably Engelbart’s greatest regret was that___________________.

A.he was too crazy about his vision of the Internet when totally ignored

B.he was not profitably rewarded for his landmark inventions of computer

C.he was admitted to the U. S. National Inventors Hall of Fame too late

D.the Internet was commercially oriented against his original intention

3.Which of the following is NOT true according to the passage?

A.Engelbart rose and fell in his all-out battle over the future of the Internet.

B.Engelbart could have succeeded in the Internet with his landmark inventions.

C.Engelbart failed to realize his ambition due to his humble position in Tymshare.

D.Engelbart could hardly resist the profit-driven trend of the growing Internet.

4.Which of the following is the best title of the passage?

A.Who Benefits from the Internet? B.Who lost the Internet Wars?

C.Who Pioneered the World Wide Web? D.Who Commercialized the Internet?

The tasty cream-filled golden sponge(海绵) cakes have been an American favorite for decades. These are just a few of the sugary treats made by the beloved Hostess brand. But after more than 80 years, Americans have to say goodbye to these iconic (标志性的) desserts. Early last week, Hostess announced it is going out of business.

"Many people have worked unbelievably long and hard to keep this from happening," said Hostess CEO Gregory F. Rayburn. "Hostess Brand has no other alternative than to begin the process of getting down and preparing for the sale of our iconic brands." Along with Twinkles (奶油蛋糕) and Wonder Bread, cupcakes and other sugary treats may disappear from the shelves.

In the past decade, Hostess has experienced difficulties with its management and high labor costs. The company had money troubles in the past, but this time there was no way to recover. Along with the loss of sugary treats comes the loss of nearly 20,000 jobs. Hostess fans hope that another company will buy out the Hostess.

The downfall of Hostess is due not just to the company's financial problems, but also to a changing America. Our country's tastes and lifestyles are not the same as they were eighty years ago. Americans have become more health-conscious, and they are demanding more healthful food products. As a manufacturer of high-calorie products, Hostess does not fit into this new way of life.

To make matters worse for Hostess, Americans do not eat as much bread as they once did. "More and more people are choosing one-dish meals," said Harry Balzar. "The tradition of bread as a side dish is going out." Americans are finding alternatives to their morning toast too. Instead they’re choosing quick snacks like yogurt and energy bars.

Will Twinkles become an image of a bygone(过去的) America? Hostess fans hope that it will secure its spot on supermarket shelves for years to come. We can only wait. And maybe eat fruit for dessert instead.

1. What caused Hostess to be in trouble in the last 10 years? (no more than 7 words)

_____________________________________________________________________

2. Can you list three disappearing sugary desserts by Hostess? (no more than 5 words)

_____________________________________________________________________

3.What makes Hostess's situation more severe? (no more than 9 words)

_____________________________________________________________________

4. What's the hope of Hostess fans about this spongy snack's future? (no more than 20 words)

We are all busy talking about and using the Internet but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

At first the Internet was only used by the government, but in the early 1970s, universities, hospitals, and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet easier.

Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mails is more and more popular among young people.
