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?

The largest-ever study of the link between city walkability and high blood pressure has been held up as evidence of the “invisible value of urban design” in improving long-term health outcomes, say researchers.
The study of around 430,000 people aged between 38 and 73 and living in 22 UK cities found significant associations between the increased walkability of a neighborhood, lower blood pressure and reduced risk of high blood pressure among its residents.
The outcomes remained consistent even after adjustments for socio-demographic (社会人口统计学), lifestyle and changing physical environment factors, though the protective effects were particularly pronounced among participants aged between 50 and 60, women, and those residing in higher density and poor neighborhoods.
The paper was published in the International Journal of Hygiene and Environmental Health this week. With high blood pressure a major risk factor for chronic (慢性的) and particularly heart diseases, researchers at the University of Hong Kong and Oxford University said the findings demonstrated the need to take notice of the health-influencing factor in urban design.
“With the increasing pace of urbanization and demographic shifts towards an ageing population, we become more likely to suffer from chronic diseases,” said Dr. Chinmoy Sarkar, an assistant professor at the Healthy High Density Cities Lab of the University of Hong Kong and lead author of the study. “The action taken to improve public health must consider the invisible value of urban planning and design.
“We are spending billions of pounds in preventing and curing heart diseases — if we are able to invest in creating healthy cities through small changes in the design of our neighborhoods to make them more activity-friendly and walkable, then probably, we will have significant savings in future healthcare expenses.”
To measure a neighborhood’s activity-promoting potential, researchers developed a set of index of walkability containing relevant urban elements, including residential and retail (零售) density, public transport, street-level movement, and distance to attractive destinations.
Poorly designed spaces generally reduced walking and physical activity, promoting the lifestyles of long time sitting down and not moving; and were harmful to social interactions, and as such associated with poorer mental and physical health.
Because walkability was “based on the underlying design of the city”, said Sarkar, cities could be modified or designed to encourage it. “Such investments in healthy design are likely to bring in long-term gains as they are enduring and common.”
1.By considering “invisible value of urban design”, people can _______.
A.reduce the ageing population
B.slow down the pace of urbanization
C.promote activity-friendly and walkable cities
D.invest in preventing and curing heart diseases
2.What can be inferred from the passage?
A.A set of index is essential to ensure that urban design promotes walkability.
B.Walkable cities can lower blood pressure and the risk of high blood pressure.
C.Chronic diseases are becoming common due to people’s neglect of their health.
D.Middle-aged women living in poor areas are less likely to benefit from increased walkability.
3.All of the following are the undesirable consequences of poorly-designed neighborhoods EXCEPT _______.
A.failing health B.unhealthy lifestyle
C.fewer social interactions D.fewer neighborhoods
4.According to Dr. Chinmoy Sarkar, _______.
A.cities should encourage the residents to engage in social interactions
B.the design of our neighborhoods should meet people’s needs for retail density
C.money invested in creating healthy cities is money saved in future healthcare expenses
D.chronic diseases will be common because of our lifestyle and the physical environment

Until now， little research has been conducted on the association between parents' friendships and the emotional well-being of their adolescent children． A new study from researchers at the University of Missouri suggests that mothers' friendships with other adults can impact their adolescent children's relationships with their own friends， particularly the negative aspects of these relationships such as conflict and opposition．
Gary． C． Glick， a doctoral candidate at MU， and Amanda Rose， professor in the Department of Psychological Sciences， studied the development of friendships and other peer relationships during adolescence and their impact on psychological adjustment． They found that adolescents may mimic the negative characteristics of their mothers' relationships in their own peer-to-peer friendships suggesting that mothers can serve as role models for their adolescents during formative years．
"Mothers who display high levels of conflict with friends may signal to their children that such behavior is acceptable， or even standard in friendships，" Glick said． "Additional findings suggest that adolescents take for granted their reactions to their mothers' conflict with adult friends which may lead to anxiety and depression．"
Previous research of this type focused on primary-aged children， but MU researchers wanted to expand their study to focus on the formative adolescent years． Youth ranging in age from 10 to 17 and their mothers were surveyed separately to measure regarded positive and negative friendship qualities in both groups． Results showed that positive friendship qualities were not always imitated by adolescents； however， negative and unfriendly relationship characteristics exhibited by mothers were much more likely to be copied by the youth studied． "We know that conflict is a normal part of any relationship---whether it is a relationship between a parent and a child， or a mother and her friends---and we're not talking physical fights but oral conflicts，" Glick said． "But being exposed to high levels of such conflict generally isn't going to be good for children． Parents should consider whether they are good role models for their children especially where their friends are concerned． When things go wrong， parents should talk with their children about how to act with their friends， but more specifically， how not to act．"
1.The word "mimic" （in Para.2）means ______ ．
A. succeed B. discover
C. possess D. imitate
2.In comparison with the previous study， the new study expanded ______ ．
A. research goals B. research themes
C. research subjects D. research approaches
3.According to Glick， parents should instruct their children ______ ．
A. how to put an end to a wrong friendship
B. how to deal with a troubled friendship
C. how to avoid any conflict with friends
D. how to establish a sincere friendship
4.What does the new study find？ ______
A. Teens mirror negative features of mom's friendships．
B. Aggressive mothers ruin their children's friendship．
C. Conflicts and opposition form children's characters．
D. Parent-child relationship affects children's growth．

阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。
The relationship between parents and children has always been a hot topic. Many students may feel 1. (stress) because of their parents. Most parents have good intentions, 2. some of them aren’t very helpful with the problems their sons and daughters have in 3. (adjust) to college, and a few of them seem to go out of their way to add to their children’s 4. (difficulty).
For one thing, parents are often not aware of the kinds of problems their children face. They don’t realize that the 5. (compete) is stronger, that the required standards of work are 6. (high), and that their children may not be prepared for 7. change. They may be upset by their children’s poor grades. At their kindest, they may 8. (gentle) ask why John or Mary isn’t doing better, whether he or she is trying as hard as he or she could, and so on. At their worst, they may threaten 9. (take) their children out of college or cut off living expenses.
Sometimes parents think it right and natural that they determine 10. their children should do with their lives. They forget that everyone is different and that each person must develop in his or her own way.
