The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.

1.What is the first paragraph mainly about?

A.A new study of different plants.

B.A big fall in crime rates.

C.Employees from various workplaces.

D.Benefits from green plants.

2.What is the function of the sensors printed on plant leaves by MIT engineer?

A.To detect plants’ lack of water

B.To change compositions of plants

C.To make the life of plants longer.

D.To test chemicals in plants.

3.What can we expect of the glowing plants in the future?

A.They will speed up energy production.

B.They may transmit electricity to the home.

C.They might help reduce energy consumption.

D.They could take the place of power plants.

4.Which of the following can be the best title for the text?

A.Can we grow more glowing plants?

B.How do we live with glowing plants?

C.Could glowing plants replace lamps?

D.How are glowing plants made pollution-free?

Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy (婴儿), every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.

In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.

In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws and construction toys; painting, scribbling and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.

But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys.

Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed — to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.

1.According to the first passage we know that as a child grows up, ______.

A. he should be allowed to choose his own toys

B. he should be given the same toys

C. he should be given fewer and fewer toys

D. he should be given different toys

2.According to the passage, the abilities a child has inherited from his parents ______.

A. determine his character

B. will not change after the age of three

C. partly determined the standard he is likely to reach

D. to a large extent determine the choice of toys

3.We learn from the passage that a child has boundless curiosity ______.

A. when he is two                    B. when he is around four

C. when he is six                     D. when he is eight

4.The passage is mainly about _______.

A. the role of play in a child’s development

B. the importance of schooling

C. the importance of pre-school education

D. the choice of toys for youngster

A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into　 accidents with yellow taxis, leading to a lower accident rate.

The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio(比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $ 2 million.

“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors.” Explained Prof Ho.

1.Why do yellow taxis result in fewer accidents?

A. Because yellow can be seen more easily.

B. Because yellow signals a warning of danger.

C. Because drivers tend to be more careful in yellow taxis.

D. Because people act more quickly in yellow surroundings.

2.What’s Prof Ho’s study based on?

A. Physical risks taxi passengers experience.

B. The economic effect of changing taxi color.

C. Data from Singapore’s largest taxi company.

D. Personal reports from taxi drivers worldwide.

3.What do Prof Ho’s words in the last paragraph suggest?

A. School buses should be painted yellow.

B. Their findings are worth popularizing.

C. Their study will be furthered.

D. Yellow should be widely used in public transport.

4.What can be the best title for the text?

A. Caution: yellow taxis ahead　　 B. Safer to ride in yellow taxis

C. Why are yellow taxis preferred?　　 D. How can colors help prevent accidents?

高三英语阅读理解中等难度题查看答案及解析

A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

Avoiding temptation (诱惑) is an effective method for maintaining self-control, which is called the “out of sight, out of mind” principle. One recent study, for instance, found office workers less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don’t believe that one’s willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower-at least to a point.

Willpower may also be made less vulnerable（脆弱）to being exhausted in the first place. Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year’s Eve is the worst possible approach. Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don’t try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you’ll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won’t require making decisions at all.

1.From the studies in the passage we learn that　　　　　　　　 .

A. people have unlimited self-control

B. high motivation ensures one’s success

C. willpower is hardly completely exhausted

D. too many temptations often lead to failure

2.The underlined phrase “tap into” in Paragraph 3 most probably means　　　　　　　　 .

A. make use of B. run out of

C. build D. increase

3.The author compares self –control to muscles　　　　　　　　 .

A. to prove the long-term effect of willpower

B. to show the significance of regular exercise

C. to argue that self-control can he easily used up

D. to explain the benefits of practicing self-control

4.To develop a good habit, which of the following does the author prefer?

A. “I will give up dessert and do exercise.”

B. “I will set three goals this new semester.”

C. “I will read an English novel every month.”

D. “I will keep myself from any temptation.”
