A new study has found the amount of antibiotics（抗生素）given to farm animals is expected to increase by two-thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic-resistant infections（感染）. Such infections are already a major public, health concern in the United States.

The World Health Organization notes when people stop living in poverty（贫困）, the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 year ago.

To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually.

Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

1.What accounts for the increasing amount of antibiotics given to farm animals?

A.The desire for new drugs. B.The less effective antibiotics.

C.The outdated farm technology. D.The need for more various foods.

2.What do most people want to do first when they get rid of poverty according to the WHO?

A.Making a lot of money. B.Focusing more on health.

C.Having more meat in their diet. D.Living in a better environment.

3.What can be inferred from the passage?

A.Antibiotics do harm to animals.

B.Antibiotics help animals stay healthy.

C.Antibiotics are used heavily in Europe.

D.Antibiotic-resistant bacteria spread to people.

4.What's the passage mainly about?

A.A new way of raising farm animals.

B.The advantages of using antibiotics.

C.The reason for banning the use of antibiotics.

D.The negative effect of antibiotics in farm animals.

An energy watchdog is alarmed about the threat to the environment from the increasing electricity needs of gadgets（小装置）like MP3 players, mobile phones and flat screen TVs.

In a report today, the Paris-based International Energy Agency says new electronic gadgets will be three times their energy consumption by 2030 to 1,700 terawatt hours（千瓦时）, which is equal to today's home electricity consumption of the United States and Japan combined.

The world would have to build around 200 new nuclear power plants just to power all the TVs, iPods, PCs and other home electronics expected to be plugged in by 2030,when the global electric bill to power them will rise to $200 billion a year, the agency said.

“Consumer electronics is the fastest growing area and the area with the least amount of policies in place to control energy efficiency, ” said Paul Waide, a senior policy analyst at the agency.

Electronic gadgets already account for about 15 percent of household electric consumption, a share that is rising rapidly as the number of these gadgets multiplies. Last year, the world spent $80 billion on electricity to power all these household electronics, the energy agency said.

“ Most of the increase in consumer electronics will be in developing countries, where economic growth is the fastest and ownership rates of gadgets are the lowest , ”Waide said.

“This will jeopardize efforts to increase energy security and reduce the amount of greenhouse gases blamed for global warming.” the agency said. Existing technologies could cut down gadgets’energy consumption by more than 30 percent at no cost or by more than 50 percent at a small cost, the agency estimates, meaning total greenhouse gas emissions（排放） from households’electronic gadgets could be held stable（稳定的） at around 500 million tons of CO2 per year.

1. How many terawatt hours did the energy consumption of new electronic gadgets reach?

A. Nearly l, 700.　　 B. Nearly 600.

C. About 200.　　　　　 D. About 60.

2. What is the condition in the area of consumer electronics?

A. There are a lot of rules to control the market.

B. There are few policies to control energy efficiency.

C. There are few choices for the customers.

D. There are lots of regulations to protect consumers' rights.

3. The underlined word “jeopardize” in the last paragraph probably means “________　 ”.

A. harm　　　　　　 B. inspire

C. strengthen　　 D. encourage

4. We can know from the last paragraph that existing technologies ___________.

A. are able to control gadgets’energy consumption

B. could do nothing about gadgets’ energy consumption

C. could only cut down gadgets’ energy consumption by 30 percent

D. cut down gadgets’energy consumption at great cost

An ageing society is one in which the population of people over the age of 60 is increasing. This is a social problem. Can we solve it with the help of robots?

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck,an expert in human animal relationship ,and Nancy Edwards, a professor of nursing, are leading the animal assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and left satisfaction. ”No one will argue that an older person is better off being more active, challenged, or stimulated(刺激),”Edwards points out.” The problem is how we promote (促进)that, especially for those without friends or help. A robotic dog could be a solution.”

In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.

”I talk to him all the time, and he responds to my voice,” says a seventy year old lady, ”When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”

The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

”At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry.” Beck says.” But it’s amazing how quickly we have given up that belief.”

”Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels. Or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”

1.Which of the following can be the best title?

A.Dogs and the Old

B.Medical Examination and the Old

C.Robots Serving the Old

D.Dogs Needn’t Feeding

2.The purpose of Beck and Edwards’ study is to____ .

A.understand human animal relationship

B.make lonely old people’s life better

C.find the causes of old people’s loneliness

D.promote the animal assisted research

3.What is the advantage of AIBO over live dogs?

A.It is easier to keep at home.

B.It can help the disabled people.

C.It responds to all the human orders.

D.It can watch TV with its owner.

4.The author seems to suggest that the future robotic dogs may　　　　 .

A. cure certain diseases

B. keep old people active

C. change people’s beliefs

D. look more like real dogs

Scientists fear rising energy bills may lead to an increase in obesity （肥胖） after discovering a link between poorly-heated homes and higher body -fat．

Researchers from the University of Stirling’s Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter．Instead, the team found that people who live in well-heated homes are more likely to have low body mass index （体重指数） levels while those who keep their heating turned down or off tend to be heavier．

Dr Michael Daly, behavioral scientist and senior lecturer, said: "We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy. In fact, the research suggests people may eat less and burn more energy when in a warmer indoor environment．

The 13-year study, published in the journal Obesity, involved more than 100,000 adults across England．

Researchers found reduced weight levels among people living in homes heated to above 23°C（73F）, which involved about 15,000 of the households studied．

Dr Daly said: "As national gas bills continue to rise faster than the rate of inflation, this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs．"

This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods, exercise classes and sporting activities, and therefore finding it easier to maintain a low BMI level．The study took age, sex, social class and other factors into account．

"The comfortable temperature of 20°C -23°C is where we feel comfortable in our clothes and are neither hot nor cold．At temperatures above this, we use more energy and we eat less because our appetite is affected．"

1.The findings of the research can be described as 　　　　　　 ．

A. horrible B. surprising

C. funny D. encouraging

2.According to the passage, with rising gas bills, people may turn down or off their heating to______.

A. stay in shape B. maintain a low BMI level

C. save money D. avoid eating more

3.Which of the following can be the best title for the passage?

A. Obesity links to poorly-heated homes

B. Well-heated home's contribute to obesity

C. Obesity--- A weighty problem in England

D. Rising energy bills help maintain a healthy weight
