For most of history scientists and mankind in general considered plants to be passive organisms just with no reason or means of communicating with one another. But new research has revealed that many plants actually ‘chat’ quite a bit over their own networks, which may also indicate that your aunt isn’t quite as crazy as you thought. You know, the one that talks to her petunias (矮牵牛花) and expects an answer.
    In fact, many plants form internal (内部的) communication networks and are able to exchange information efficiently. These connections enable the plants to share information via internal channels in a manner very similar to computer networks. So what kind of things do plants tell each other?
    Researcher Josef Stuefer found that one purpose for plants having their own “chat systems” is to warn each other. He and his colleagues were the first to prove that clover (三叶草) plants do indeed warn each other via these network links if enemies are nearby. For example, if one of the plants is attacked by caterpillars (毛虫), it will warn the other members of the network via an internal signal. After receiving a warning, the other plants will strengthen their protective chemical and mechanical resistance so that they are less attractive to advancing caterpillars. This early warning system allows the plants to stay one step ahead of their enemies. Experimental research has revealed that this communication significantly limits the damage to the plants.
    It is also known that plants have “family values”, with new research revealing they have the ability to recognize close relatives in order to help each other survive. Research found plants from the same species of beach-dwelling wildflowers, for example, grew aggressively (侵略地) alongside unrelated neighbors but were less competitive when they shared soil with their siblings. Some researchers think that plants must communicate through their roots, identifying themselves using tiny chemical signatures specific to each plant’s family.

The research shows that our current concept of plants is probably a poor reflection of reality. Scientists are eager to discover in what ways, and to what extent, plants communicate with each other.

All areas of the world face a nurses shortage. But the shortage is most severe in developing countries. Many of their nurses move to the more developed nations for better pay, better working conditions and better chances for career development. For example, nearly 2,000 nurses left the Caribbean between 2002 and 2006.

The Caribbean nations currently have about 1 nurse for every 1,000 people. The ratio(比例) of nurses to population is about 10 times higher in the United States and countries in the European Union(EU). Now, more than 21,000 nurses who trained in the Caribbean are working in the United States, Canada and Britain.

Gaetan Lafortune is an official of the Organization for Economic Cooperation and Development(O.E.C.D) in Paris. He says the nurses shortage also affects industrialized countries. He says, “There is concern in most O.E.C.D.countries that the number of nurses is too small to meet the demand. And what is more worrying is that their concern is sort of growing.” Mr Lafortune says a large number of nurses are expected to retire within the next 10 years. At the same time, the health care needs of aging populations are expected to grow, intensifying the shortage of nurses.

Gaetan Lafortune said, “In the U.S., for instance, some researchers have found that there may be a shortage of close to a million nurses by 2020.” The United States is 1 of the 21 countries in the O.C.E.D. Gaetan Lafortune says in the recent years many of the countries increased their efforts to hire foreign nurses. As a result of that, O.E.C.D. countries were mainly exporting their shortage problem to countries that may have an even greater need for these nurses.

What will be the main causes of the global nurses shortage in the next 10 years?

a. The demand for nurses will decrease.

b. Many nurses will be too old to work.

c. Many rich countries will hire more foreign nurses.

d. Nurses are often looked down upon.

e. Aging populations will increase rapidly

A. a and b B. b and c C. b and e D. c and d

The underlined word “intensify” in para. 3 means “________”.

A. refuse to offer equal pay to foreign nurses

B. have at least one nurse out of 100 people

C. don’t like to train nurses of their own countries

What does the text mainly tell us?

A. Nursing is no longer a worthwhile profession in most countries.

Mary was seven years old. Her parents recently moved to a new town, and so Mary was going to a 36   school, which was a few kilometers from the house they lived in now. A school bus going around picked up 37 every morning and brought them back to their 38 every afternoon, and as both of Mary’s parents 39 to go to work, she always went on this bus.
Mary’s parents always 40  their alarm clock for seven o’clock so that none of them would be 41   . But one morning the alarm 42 to go off, and it was not until a quarter past eight that Mary’s mother suddenly 43 , looked at the clock and said, “What’s ever happened to that clock?” and then 44   into Mary’s room to wake her up.
“I’m sorry, dear,” she said, “ 45 you’ll have to wash and dress very quickly, have an even 46 breakfast and then I’ll 47 you to school on my way to the office.”
“But how can you find the   48, Mum?” Mary said, “You’ve been to school only once.”
“Yes,” her mother answered, “but you’ve done the   49   several times now on the bus, so you can be my guide to get there, can’t you?”
“Oh, yes,” said Mary, “I suppose so.” She washed, and 50  and had a quick breakfast, and then they set off. Mary told her mother to turn each time they came to a place she 51 .In this way she made her mother drive round most of the town   52  they got to her school. When they arrived, her mother saw that it was not really very far from her house.
“Why ever did you make me go such a long way round, Mary, instead of the most    53    way?” her mother asked her.
“Well, Mum,” answered Mary, “it was because I didn’t know   54  else to get here. That’s the way our bus always goes to   55   the other children to school.

I don' t know if I am missing the greatest pleasure of my life. I am no fan of computer games. Some guys forget themselves and forget day and night when they play games. For example, a colleague has been playing since 1 o’clock this morning and now it is 7 o'clock. He is still commanding his army of little people to attack strange-looking animals. Some games could be fun, 1 admit, and it is therefore understandable that such a game catches players. For example, games like Red Storm or some role-play games, you do something and try to outwit(智胜) your computer. You get some fun out of these games. It is understandable that such a game pushes you into a pitfall(陷阱) of pleasures. But some games look quite stupid and simple. Again for example, my colleague has been interested in Stone Age, a cartoon-like game rooted in prehistoric time. The game is well made, full of strange people and animals and you can play on line with partners. You can have reference books to study so as to shortcut your rivals(对手) and increase your own conquering power.

I believe some kinds of games are really created for adults. But seeing these adults play the simple games with such interest, I just wonder if there is something wrong with me and if I am losing the greatest possible fun of my life. I ask why I don’t bother playing such games and why I seem to have some aversion(讨厌) to such games. I have no answers. Certainly computer games is no my idea of a good time. I would rather listen to some music or read a book. Take music for example. Good music tops my list of pleasures. Nothing could beat music, all in a harmony of sounds and emotions. But how about games? Why am I so strongly biased(偏见) against such games?
