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．"

The pursuit of longevity has long been on people’s minds, prompting an abundance of research on the effects of food and diet on the human lifespan. According to recent research from the UC Irvine Institute, drinking coffee and wine could help you live longer.

The 90+ Study evaluated more than 1,600 people over the age of 90 for their lifestyle habits and other qualities that might have contributed to their longevity.

Participants were visited every six months, when they were given various tests. Researchers also collected information about the participants’ diets, lifestyles, and medical histories.

They found out that two of the habits that helped preserve lives the most are drinking alcohol and coffee. “I have no explanation for it,” admitted Dr Claudia Kawas, “but I do firmly believe that moderate (适度的) drinking improves longevity.” So should we all be drinking more coffee and wine? While that would be great news, the research may not be as definitive as it seems.

“Most studies about alcohol consumption, including The 90+ Study, are observational, so we　 can only say that something about drinking is associated with health and longevity,” registered dietitian Jennifer Markowitz told The Daily Meal.

“I’d be curious to see if the coffee and alcohol drinkers shared other important habits or lifestyle factors that might also play into their longevity.”

In other words, it might not be the wine and coffee that’s helping people live longer, but the two substances do have some considerable health benefits. “Wine and coffee are packed with antioxidants(抗氧化剂) which are known to protect our bodies from damage caused by free radicals,” explained registered dietitian Keri Gans to The Daily Meal. “Research on antioxidants has shown several heath benefits, including the possibility they may lower the risk of type 2 diabetes, improve cognitive function, decrease the risk of dementia, and lower the risk of heart disease.”

Moderate drinking can be beneficial according to other studies—so long as it’s moderate.

1.What’s the passage mainly about?

A. Antioxidants having a positive effect on the lifespan.

B. The effects of food and diet on the human lifespan.

C. Advocating drinking wine and coffee in our daily life.

D. Moderate drinking helping people live longer.

2.The information was collected about the participants in the 90+ Study except ________.

A. food consumption

B. lifestyle

C. hobbies

D. medical history

3.How can the wine and coffee benefit people’s health?

A. They provide people with essential nutrition.

B. They are rich in antioxidants.

C. They protect free radicals in human bodies.

D. They can bring relief to pain.

4.What can we infer from the passage?

A. Not all the people participating in the study are over 90.

B. Most studies about alcohol consumption are based on observation.

C. Over-drinking can also be beneficial according to other studies.

D. Antioxidants can cure type 2 diabetes.

Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc, what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.

Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.

The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.

Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.

The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.

The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.

1.The purpose of the experiment is ________.

A. to combine the computer and the human brain

B. to make bear swim

C. to make some stupid dog turn clever

D. to enlarge the capacity of human brain

2.Which of the following statements is TRUE?

A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.

B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.

C. The second experiment wasn’t an entire transplant of the memory area.

D. The Idiot was an animal with memory before brain experiment

3.What does the underlined word “success” refer to?

A. The two dogs woke up.

B. They were both good at memorizing.

C. The Idiot grasped all the abilities of Genius.

D. The Genius grasped all the abilities of Idiot.

4.According to the text, we can infer ________.

A. a person can know more after the experiment

B. a bear can swim after being transferred a chip with related useful information

C. a dog can become clever after entire transplant of the memory area

D. it is really good for animals to have been involved in the transplant experiment

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?
