Directions: For each blank in the following passage there are four words or phrases marked A,B,C and D. Fill in each blank with a word or phrase that best fits the context.

Being alone in outer space can be 36 . That is one reason why astronauts on solo(单独的) space flights were given plenty of work to keep them 37 . They were also in constant communication with people on the earth. 38 , being with people from whom you cannot get away might be even harder than being alone. This is what happens on long submarine(潜水艇) voyages. It will also happen on 39 space flights in the future. Will there be special problems of adjustment under such conditions?

Scientists have studied the reactions of men to one another during long submarine voyages. They have also found that the longer the voyage lasts, the more serious the problem of 40 is. When men are 41 together for a long period, they begin to feel 42 . Everyone has little habits of speaking and behaving that are ordinarily acceptable. In the limited space over a long period of time, however, these little habits may become very 43 .

Apparently, although no one wants to be 44 all the time, everyone needs some degree of privacy. When people are enclosed together, they are in what is called stress situation. That means that they are under an unusual amount of 45 or stress.

People who are well-adjusted are able to 46 stress situations better than others. That is one reason why so much care is taken in 47 our astronauts. These men undergo a long period of testing and training. One of the things tested is their behavior under stress, and thus they can do better than ordinary people.

Do you have any skiing equipment you no longer need? A ski school in the far north of India could put it to good use.

In March we published a photo story about the extraordinary Zsnskar region in northern India，which is cut off from the outside world for more than seven months of the year，and only accessible (可通行的)via a frozen river．We also included information about the limited use of skiing in the region and the recent creation of the Zanskar Ski School:

“Despite the difficulties of travelling through the region when the snow comes，skiing hasn’t traditionally been used as a means of transport by the locals，largely because trees don't grow here, so there is little in the way of raw materials from which to make skis．In 1995, a group of British scientists in the region noticed the lack of skis and one of them returned to set up the Zanskar Ski School in Padam．The school provides lessons for a small fee and rents skis to the local people. Among the benefits that the school hopes to bring are improved education—children often find it difficult to get to school through the deep snow—and the possibility of offering ski tours to tourists in the future．So far，more than 300 local people have received training，and local doctors and policemen regularly borrow skis.”

But what we weren't able to include in the article is that the ski school is always on the look out for old skiing equipment—particularly of a size suitable for children—and, I thought. Now the European ski season is drawing to a close，there might be a few of you out there who have some old equipment you'd like to see go to a good home．If that's the ease you can get in touch with the school via their website www.zanskarski school.org.

Even when you’re extremely busy, you aren’t using your time with 100% efficiency. There are gaps in everyone’s schedule where they aren’t doing anything important. Even if your schedule has no gaps, there is probably lots of time where you aren’t working as fast or as effectively as you possibly could.

Why aren’t you completely efficient? It’s because time isn’t the limiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions(消遣). Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate(拖延) and slow down on tasks throughout the day.

The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you’re tired, you can have ample time and still not get everything done. Your attention ability is also limited, because even if there are a million things that need to be done, you can only focus on one or two at a time.

You might not be able to insert another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can add an hour or two into their schedule without cancelling anything. The reason it’s hard to “find time” isn’t a lack of time. It’s because you don’t have enough energy left to focus on something else that needs to fit into your day.

I first suspected time wasn’t the real problem during an extremely busy period in my life over a year ago. I was insanely （发疯地）busy, but at that time I still exercised regularly. I had daily to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, I stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this odd experience? I believe you have known it.

1.If someone can’t work with 100% efficiency, the most important limiting factor is ________.

A．a schedule without gaps B．breaks and distractions

C．the limited time D．the limited energy

2.According to paragraph 4, everyone, including the extremely busy people, can ___________.

A．work without any rest B．focus on many things at a time

A．He had a longer daily to-do lists with over twenty items.

B．He stopped doing exercise because of the lack of energy.

C．He found it hard to find time to exercise because he was busier.

D．He pushed most of the things later and later in his schedule.

4.The writer gives the example of himself in the last paragraph in order to ___________.

A．prove what the real limiting factor is

B．show us how busily he needs to work

C．explain how important a healthy body is

D．tell us what an odd experience he has

5.What is the best title of the passage?

A．Are You Really Lack of Time? B．How Can You Work Efficiently?

For years scientists have been concerned about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired,to suffer eye pain, headache and other problems.Some pollutants(污染物)can cause breathing disorders,diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.People began to notice the problem in the early 1970s.It is said that when builders began making houses and offices they did not want to waste energy.To do this,they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.As the problem became more serious, scientists began searching for a way to deal with it.They discovered a natural pollution control system for building－green plants.Scientists do not really know how plants control air pollution.They believe that a plant's leaves absorb or take in the pollutants.In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space.Studies of different plants show that each absorbs different chemicals.So the most effective way to clean the air is to use different kinds of plants.Having green plants inside your house can make it a prettier and healthier place.

77.What is the topic of the passage?

A.Air pollution.
