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

Researchers say public mistrust of vaccines（疫苗）is causing diseases like measles（麻疹）and yellow fever to spread. The scientists said the lower levels of trust can lead to people refusing vaccines. This, in turn, can cause diseases to spread quickly, they warmed.

But the researchers said they also found a high level of support worldwide for vaccinating children against disease.

The researchers questioned 66,000 people in 67 countries to discover their ideas on whether vaccines are important, safe and effective. The survey showed people in Southeast Asia had the highest level of trust in vaccines. Africa showed the second highest level of confidence. Europeans showed the lowest level of confidence in vaccines. In France, 41 percent of the population questioned the safety of vaccines.

Heidi Larson is with the London School of Hygiene and Tropical Medicine. She says recent media reports of problems involving vaccines have hurt public confidence in France. Larson noted that many Europeans worried about reports of possible links between hepatitis B vaccines（乙型肝炎疫苗）and the disease multiple sclerosis（多发性硬化症）. But she said scientists found no linkage between the two. Mistrust in France was also driven by public reaction to the H1N1 influenza（甲型H1N1流感）outbreak fears in 2009. The French government spent $1.4 billion on 94 million doses of the vaccine. The majority were sold or destroyed.

The findings come as a major yellow fever vaccination program has been launched in the Democratic Republic of Congo and Angola. The disease has already killed hundreds of people in the area. The World Health Organization aims to vaccinate over 15 million people in both countries. “If everyone agrees to be vaccinated, we can remove yellow fever from our country,” said Mosala Mireille, one of the doctors directing the program.

1.The author develops the Paragraph 1 mainly ________.

A. by telling experiences　　 B. by giving instructions

C. by offering descriptions　　 D. by analyzing cause and effect

2.The underlined words “The disease” in the last paragraph probably refer to ________.

A. measles　　 B. yellow fever

C. H1N1 influenza　　 D. multiple sclerosis

3.Mistrust of vaccines in France was driven by the following reasons except ________.

A. media reports of problems linked to vaccines

B. public reaction to the H1N1 influenza outbreak fears in 2009

C. connections between hepatitis B vaccines and the disease multiple sclerosis

D. most of the doses of the vaccine were sold or disposed of by the French government

4.Mosala Mireille’s attitude towards the yellow fever vaccination program is ________.

A. Expectant　　 B. Skeptical

C. Critical　　 D. Cautious

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?
