Because plants cannot move or talk, it is believed that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
60. Why was Backster surprised at the results of his studies?
A. Because he found someone had just cut down a tree.
B. Because he destroyed a plant by pulling it out of its pot.
C. Because he found that plants could move and speak after all.
D. Because he found that plants could express feelings of shock.
61. The plants sent out signals _____.
A. only when Backster Started to destroy plants
B. when Backster destroyed plants or other living things
C. only when he destroyed things such as insects
D. only when Backster placed the galvanometer on the leaves of the plants
62. The scientist called Sauvin _____.
A. did not agree with Backster’s ideas
B. did not get the same sort of results as Backster did
C. found out some of the same things that Backster did
D. got different results from Backster’s
63. Which of the following is true according to the passage?
A. The electrical charge plants carry may shock or frighten us.
B. A tree will signal when it has been cut down.
C. Sauvin could make his plants send out signals some distance away.
D. Plants have feelings because they can receive signals without moving.

A new study suggests that the round-the-clock(24小时不断的)availability that cell phone have brought to people’s lives may be taking a toll on family life.The study,which followed more than 1,300 adults over 2 years, found that those who consistently used a mobile phone throughout the study period were more likely to report negative “spillover’’ between work and home life—and,in turn, less satisfaction with their family life.
Spillover essentially(本质上)means that the line between work and home begins to become unclear.Work life may invade home life when a parent is taking job—related calIs at home,for instance--or family issues may start to take up work time.For example,a child may call mom at work,telling her "microwave exploded” explained Noelle Chesley,an assistant professor of sociology at the University of Wisconsin—Milwaukee and the author of the study. The problem with cell phones seems to be that they are allowing for ever more spillover between work and home.
This may be especially true for working women,the study found. Among men,consistent use of mobile phones seemed to allow more work issues to creep (潜入)into family time.But for women,the spillover tended to go in both directions. Being “connected” meant that work cut into home time,and family issues came into work life.
Cell phones seem to be opening more lines for stressful exchanges among family member.But there may be ways to control the spillover,according to Chesley.Employers, she said,could look at their policies on contacting employees after hours to make sure their expectations are “reasonable”.For their part,employees could decide that cell phones go off during family time, Chesley said.
64.What does the underlined phrase “taking a toll on’’ probably mean in Paragraph 1?
A. Explaining. B. Influencing. C. Damaging. D. Extending
65.According to Chesley,what is the best solution to the problem caused by cell
phones?
A. Refuse to use cell phones.
B. Separate work hours from family time.
C. Ignore coming calls during family time.
D. Encourage women to stay at home.
66.We can learn from the passage that ___________________.
A.spillover makes the line between work and home unclear
B.cell phones seem to be convenient to families
C.cell phones affect men as much as women
D.we can do nothing to solve the problem
67. What is the main idea of the passage?
A .How to control the negative spillover caused by cell phones.
B. Cell phones cause negative “spillover’’ between work and home life.
C. Consistent use of cell phones makes people feel less satisfied with their work.
D.How work life invades home life.
Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use.This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives.
To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so .Medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural society with a much lower population density than it is today.It had minimal effect on biodiversity, and any pollution it brought about was typically localized.In terms of energy use and the nutrients captured in the product it was relatively inefficient.
Contrast this with farming since the start of the industrial revolution.Competition from overseas led farmers to specialize and increase yields.Throughout this period food became cheaper, safe and more reliable.However, these changes have also led to habitat loss and to diminishing biodiversity.
What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050,yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions.
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th.This will require radical(激进的)thinking.For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones.We also need to abandon the notion that agriculture can be “zero impact”.The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage.Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used.There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity.It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting, but we do not know whether lower carbon footprints will always be better for biodiversity.
What is crucial is recognizing that sustainable agriculture is not just about sustainable food production.
72.How do people often measure progress in agriculture?
A.By its productivity B. By its impact on the environment
C.By its sustainability D.By its contribution to economic growth
73.What does the author think of traditional farming practices?
A.They have remained the same over the centuries
B.They have not kept pace with population growth
C.They are not necessarily sustainable
D.They are environmentally friendly
74.What will agriculture be like in the 21st century?
A.It will go through radical changes
B.It will supply more animal products
C.It will abandon traditional farming practices
D.It will cause zero damage to the environment
75.What is the author’s purpose in writing this passage?
A.To remind people of the need of sustainable development
B.To suggest ways of ensuring sustainable food production
C.To advance new criteria for measuring farming progress
D.To urge people to rethink what sustainable agriculture is.

Another man-made wonder of the United States was built long before the nation was established. About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Colorado, where 600 cliff dwellings are now part of the Mesa Verde National Park.
Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock, which connected buildings containing hundreds of rooms.
The rock walls have protected the buildings from severe weather in the area; therefore, they remain mostly unchanged in the hundreds of years since they were built.
Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the 1962 World"s Fair.
The 184-meter-tall structure was designed by Edward Carlson, which has a wide base on the ground, with its middle narrow and a large ring-like structure on top. The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories. The saucer includes an observation area and eating place. The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.
The Space Needle, only costing about $4,500,000, was not very costly, and was designed and completed in about a year and opened on the first day of the World"s Fair.
Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city.
56.What the passage before this one can be about?
A.Some natural wonders in the world.
B.Sightseeing in the US.

A. It is a man-made wonder in Washington, D.C..
B. Edward Carlson built the structure.
C. It has a ring-like structure on top.

The “Bystander Apathy Effect” was first studied by researchers in New York after neighbours ignored --- and in some cases turned up the volume on their TVs --- the cries of a woman as she was murdered (over a half-hour period). With regard to helping those in difficulty generally, they found that:
women are helped more than men;
men help more than women;
attractive women are helped more than unattractive women.
Other factors relate to the number of people in the area, whether the person is thought to be in trouble through their own fault, and whether a person sees himself as being able to help.
According to Adrian Furnham, Professor of University College, London, there are three reasons why we tend to stand by doing nothing:
“Shifting of responsibility” --- the more people there are, the less likely help is to be given. Each person excuses himself by thinking someone else will help, so that the more “other people” there are, the greater the total shifting of responsibility.
“Fear of making a mistake” --- situations are often not clear. People think that those involved in an incident may know each other or it may be a joke, so a fear of embarrassment makes them keep themselves to themselves.
“Fear of the consequences if attention is turned on you, and the person is violent.”
Laurie Taylor, Professor of Sociology at London University, says: “In the experiments I’ve seen on intervention(介入), much depends on the neighborhood or setting. There is a silence on public transport which is hard to break. We are embarrassed to draw attention to something that is happening, while in a football match, people get involved , and a fight would easily follow.”
Psychotherapist Alan Dupuy identifies the importance of the individual: “the British as a whole have some difficulty intervention, but there are exceptional individuals in every group who are prepared to intervene, regardless of their own safety. These would be people with a strong moral code or religious ideals.”
60. Which of the following statements is true according to the passage?
A. Pretty women are more likely to be helped.
B. People on a bus are more likely to stop a crime.
C. Religious people are more likely to look on.
D. Criminals are more likely to harm women.
61. Which factor is NOT related with intervention according to the passage?
A. Sex. B. Nationality. C. Profession. D. Setting.
62. Which phenomenon can be described as the “Bystander Apathy Effect”?
A. A man is more likely to help than a woman.
B. In a football match, people get involved in a fight.
C. Seeing a murder, people feel sorry that it should have happened.
D. On hearing a cry for help, people keep themselves to themselves.
63. The author wrote this article _______.
A. to explain why bystanders behave as they do
B. to urge people to stand out when in need
C. to criticize the selfishness of bystanders
D. to analyze the weakness of human nature
