US universities are among the best in the world. Since World War Ⅱ, American scientists --- mostly working in universties or colleges --- have won more than half of all Nobel Prizes in physics and medicine. Foreign students rush to the United States by the tens of thousands. Last year they earned more than one quarter of the doctoral degrees awarded in the country. Yet while American universities produce the great research and great graduate program, they sometimes pay little attention to the task that lies at their very core: the teaching of undergraduate students.

With the increase in fees, educators feel obliged to improve undergraduate teaching. In speeches and interviews the nation’s higher educators have rediscovered teaching. Robert Rosenzweig, president of the Association of American Universities,  said,  “Our organization was never very concerned about teaching. In the last 18 months, we have spent more time on undergraduate education than on any other subject.”

Despite such promising efforts, no one doubts that research still outranks teaching at some of the leading universities, not least because it is a surer and faster way to earn status. Some people don’t think it has to be that way. They argue that the reward system for college faculty can be changed, so that professors will be encouraged to devote more time and effort to teaching. They say that they are beginning to believe that the first ten years of the 21st century may come to be remembered as the decade of the undergraduate.

That would bring it full circle. For more than two centuries after the founding of Harvard College in 1636, the instruction of undergraduate students was an essential condition of American higher education.

1.According to the passage, at some of the leading American universities ________.

A．research is declining in importance          B．teaching now ranks above research

C．teaching is a sure way to gain position        D．research still ranks above teaching

2.It is implied in the passage that about 200 years ago undergraduate instruction ________.

A．began to change all of a sudden

B．was already threatened by research work

C．was the central part of higher education

D．began to be neglected in most universities

3.What would be the best title for the passage?

A．University education in the US             B．University education challenged

C．Teaching and research in universities        D．Undergraduate teaching rediscovered

Scientists warn that our earth is drowning in plastic. The world’s cities produce 2 billion tons of rubbish every year. That number is expected to rise to 3 billion tons by 2050.

We often buy packaged goods but that packaging is often made of plastic. Now, it may be changing. A new environmentally friendly shopping model, called Loop, was recently launched at the World Economic Forum in Davos, Switzerland. It aims to replace throwaway containers with reusable ones. This is what some people call the zero-waste movement. The main belief driving this movement is that much of the trash we create is unnecessary.

Loop is the idea of TerraCycle, a recycling company. It first came from the “milkman model” of the 1950s in the US. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zero-waste. Loop will work the same way. Instead of throwing away, the product comes in a reusable one. When the product is all gone, someone will collect and clean the old container, fill it up and then return it to you.

At the start, Loop will offer about 300 products. Proctor & Gamble will start by selling 10 products on Loop as a test. If the results are good, more products will be added later.

Representatives from Greenpeace also joined in the discussion about Loop at Davos. Jennifer Morgan said that “Greenpeace welcomes the aim of the Loop Alliance to move away from throwaway culture and disposability. But I doubt whether companies worldwide are ready to change their business models”.

Loop is set to launch later in three eastern U. S. states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the U. S. West Coast, Toronto, Canada and Britain by the end of this year.

1.The purpose of Loop is to___________.

A.make packaging easier

B.reduce the plastic waste

C.lower the production cost

D.change shopping model

2.What is the third paragraph mainly about?

A.The origin of the idea of Loop.

B.The way to recycle milk bottles.

C.The future of shopping pattern.

D.The benefit of recycling containers.

3.What is Morgan’s attitude towards the current situation of loop?

A.Optimistic. B.Desperate.

C.Worried. D.Ambiguous.

4.What is the author’s purpose in writing the text?

A.To show scientists’ concern about plastic.

B.To present us benefits of recycling plastic.

C.To introduce the zero-waste shopping model.

D.To inform us of an environmental issue.

It is a common fear among users of Facebook and other social media around the world—how to deal with a friend request from your boss or employee.

A survey released on Thursday found that 56 percent of Americans say it is irresponsible to be friends with a boss and 62 percent say it is wrong to be friends with an employee. But 76 percent believe it is acceptable to be friends with a workplace peer，according to the survey of 1，000 people by Liberty Mutual’s Responsibility Project.

"When the roles change what do you do then? Do you unfriend someone if they have now been promoted to be your boss or if you’re now their boss，”said researcher Kelly Holland. "We get into some really sticky situations there in terms of what people will think is responsible，”she said.

When using social media at work，73 percent say it is not appropriate to update your Facebook status，82 percent say you should not upload photos，72 percent believe tweeting is wrong and 79 percent say it is not acceptable to watch online videos. Yet 66 percent say it is fine to check your personal email while at work.

“When people focus on responsibility，they know what the responsible thing is to do but whether they are doing that in practice or not is a different story,”said Holland.

Americans are split on whether companies should review the social media profiles of job candidates with 52 percent saying it is appropriate and 48 percent saying it is unacceptable. Social media can also lead to some difficult decisions when it comes to family and relationships. Sixty percent of those polled say that it is“completely acceptable" to unfriend an ex-boyfriend or ex-girlfriend. More than 40 percent of parents believe it is irresponsible to post photos of children online. Thirty one percent monitor their children's Facebook accounts and almost 70 percent are friends with their children on Facebook or MySpace. But 72 percent limit the time their children spend on social media networks.
