It is thought that crying is hardly an activity encouraged by society. Tear, whether they are of sorrow, anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears (落泪者) is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything possible to put an end to the emotional tears. But judging from recent studies of crying behavior, both those responses to tears are often inappropriate and may even be counterproductive (适得其反).
Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance (increase) survival.
Although some observers have suggested that crying is a way to ask for assistance form others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress, University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.
Other researchers are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs. At Tulane University’s Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse, to study the causes of “dry eye” syndrome（综合症）and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants. What does the phrase “both those responses” in Paragraph 1 refer to ?
| A．Crying out of sorrow and shedding tears for happiness. |
| B．The embarrassment and unpleasant sensation of the observers. |
| C．The tear shedder’s apology and the observer’s effort to stop the crying. |
| D．Linking illness with crying and finding the chemical composition of tears. |
From the passage we can infer that .
| A．it is unnatural for people to shed tears |
| B．we can reduce our stress by shedding tears |
| C．shedders of tears can’t get help by crying loudly |
| D．unlike animals, humans can shed tears for survival |
What does the passage mainly talk about?
| A．Roles of emotional tears. |
| B．functions of shedding tears. |
| C．Unwelcome shedders of tears. |
| D．Research on the effects of tears. |

Let children learn to judge their own work. A child who learns to talk does not learn by being corrected all the time. If corrected too much., he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him. Little by little, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught-to walk, run, climb, whistle, ride a bicycle-compare their performances with those of more skilled people, and slowly make the needed changes.
But in school we never give a child a chance to find out his mistakes and correct them himself. We do it all for his act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says , what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(daily) work? Our job should be to help the children when they tell us that they can’t find the way to get to measure their own understanding, how to know what they know or do not know. According to the passage, the best way for children to learn things is by ______.
| A．listening to the advice of grown-ups. |

People in the United States honor their parents with two special days: Mother’s Day on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer an opportunity to think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child-care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A while one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery. On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are more valuable than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting cards stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays. Which is not a reason for children to show love and respect for parents?
| A．Parents bring up the children. |
| B．Parents give love and care to children. |
| C．Parents educate children to be good persons. |
| D．Parents pass away before children grow up. |
. What do you know from the passage?
| A．Mother’s Day and Father’s Day are both in May. |
| B．Fewer women worked outside the home in the past. |
| C．Not all the children respect their parents. |
| D．Fathers are not as important as mothers at home. |
Which do you think is right about “carnation”?
| A．It only has two kinds of colors. |
| B．It refers to the special clothes people wear on Mother’s Day or Father’s Day. |
| C．It’s a kind of flower showing love and best wishes. |
| D．People can wear carnations only on the second Sunday in May. |
On Mother’s Day and Father’s Day, ________.

This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!．Why does Virgin Airlines try to replace normal fuel with biofuel?
| A．To cut down the flight cost of the company. |
| B．To remove some hurdles for the biofuel to work. |
| C．To reduce CO2 emissions from airplanes. |
| D．To test plane engines on biofuel. |
．Which is NOT true for a full biofuel switch of airplanes?
A Biofuel cannot run for long flights.
B．Biofuel cannot work at high altitudes.
C．Man has not enough land to grow extra crops for biofuel.
D．It’s not easy for sewage treatment plants to manufacture biofuel.．One of the hurdles to be overcome for a full biofuel switch is to.
| A．alter the engine for airplanes |
| B．make biofuel burn consistently |
| C．open more land to grow more crops |
| D．develop sewage treatment plants |
．We can infer from the last paragraph that.
| A．there is a long way to go for a complete switch to alternative fuel |
| B．it won’t be long before alternative fuel comes into use |
| C．airlines, oil companies and airplane manufacturers are reliable |
| D．alternative fuel has a bright future |
．Which of the following can best serves as the title of this passage?
| A．Biofuel-Alternative Fuel Sources. |
| B．The First Commercial Flight Powered by Biofuel. |
| C．How to Reduce CO2 Emissions from Airplanes. |
| D．Vigin Airlines Trying to Alter Fuel Sources. |
It is a matter of common observation that although money income keeps going up over the years, we never seem to become richer. Prices are rising continuously. This condition is what we call inflation: the money supply is becoming inflated so that each unit of it becomes less valuable. We have got used to higher and higher rates of inflation in recent years. What could be bought twenty years ago for one pound now costs well over 2 pounds. And at present this rate of inflation seems to be rising rather than falling. If in the real world our money incomes go up at the same rate as prices do. One might think that inflation doesn’t matter. But it does ------.When money is losing value it also loses one of the qualities of a good money—stability of value. It is no longer acceptable as a store of value; and it becomes an unsuitable means of delayed payment. Nobody wants to hold a wasting possession, so people try to get rid of money as quickly as possible. Inflation therefore simply stimulates（刺激）our spending and discourages saving.From the passage we can know that inflation is a situation in which________.
| A．everyone’s incomes rise |
| B．money will hold its value |
| C．we can watch our money grow |
| D．money constantly loses its value |
．In the writer’s view, if incomes and prices rise at the same rate, ________.
| A．inflation maybe still be a problem |
| B．we have nothing to worry about |
| C．inflation is no longer a problem |
| D．we will become richer and richer |
．Under inflation people are likely to ________.
| A．go to the bank more often than usual |
| B．save more money since their incomes rise |
| C．spend money quickly rather than to save it |
| D．keep money at home instead of going to banks |
．We can conclude according to the passage that ________.
| A．the writer is a government official |
| B．the writer is worried about inflation |
| C．the writer encourages people to spend money |
| D．the writer has become richer because of inflation |
. Which of the following words is omitted at the end of the underlined sentence “But it does”?
| A．matter, | B．goes. | C．rises | D．fall |
