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.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. |
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. |
The underlined word “jeopardize” in the last paragraph probably means “ ”.
| A．harm | B．inspire | C．strengthen | D．encourage |
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 |
Anyone who cares about what schools and colleges teach and how their students learn will be interested in the memoir（回忆录）of Ralph W. Tyler, who is one of the most famous men in American education.
Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching while teaching as a science teacher in South Dakota and changed his major from medicine to education.
Graduate work at the University of Chicago found him connected with honorable educators Charles Judd and W. W. Charters, whose ideas of teaching and testing had an effect on his later work. In 1927, he became a teacher of Ohio State University where he further developed a new method of testing.
Tyler became well-known nationality in 1938, when he carried his work with the Eight-Year Study from Ohio State University to the University of Chicago at the invitation of Robert Hutchins.
Tyler was the first director of the Center for Advanced Study in the Behavioral Sciences at Stanford, a position he held for fourteen years. There, he firmly believed that researchers should be free to seek an independent（独立的）spirit in their work.
Although Tyler officially retired in 1967, he never actually retired. He served on a long list of educational organizations in the United States and abroad. Even in his 80s he traveled across the country to advise teachers and management people on how to set objectives（目标）that develop the best teaching and learning within their schools. Who are most probably interested in Ralph W. Tyler’s memoir?
| A．Top managers. | B．Language learners. |
| C．Serious educators. | D．Science organizations. |
The words “hooked oh teaching” underlined in Paragraph 2 probably mean ________.
| A．attracted to teaching | B．tired of teaching |
| C．satisfied with teaching | D．unhappy about teaching |
Where did Tyler work as the leader of a research center for over 10 years?
| A．The University of Chicago. | B．Stanford University. |
| C．Ohio State University. | D．Nebraska University. |
Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie.
Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine, I'll take someone out.
The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She's like a different child when there's no one else around," Christie shared with me quickly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering（口吃的）son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who's always a follower when around other children shines as a leader during our times together.
The "Mommy and Me" time allows us to be simply alone and away with each child ---talking, sharing, and laughing, which has been the biggest gain. Every child deserves（应得到）to be an only child at least once in a while.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced（影响）us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting. Why was the bike so important to the couple?
| A．The man’s job was bike racing. | B．It was their only possession. |
| C．It was a nice Kona 18 speed. | D．They used it for work and daily life. |
We can infer from the text that ____________.
| A．the couple worked 60 hours a week. | B．people were busy before Christmas |
| C．the stranger brought over the bike | D．life was hard for the young family. |
How did people get to know the couple’s problem?
| A．From radio broadcasts. | B．From a newspaper. |
| C．From TV news. | D．From a stranger. |
What do the couple learn from their experience?
| A．Strangers are usually of little help. | B．One should take care of their bike. |
| C．News reports make people famous. | D．An act of kindness can mean a lot. |
Malaria, the world's most widespread parasitic(寄生虫引起的) disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染). They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next. According to paragraph 1, many people don't seek care because___.
| A．they are too poor |
| B．it is unusual to seek care |
| C．they can remain unaffected for long |
| D．there are too many people suffering from the disease |
People suffering from malaria___.
| A．have to kill female mosquitoes |
| B．have ability to defend parasites |
| C．have their red blood cells infected |
| D．have sudden fever, followed by chills |
Which of the following may be the reason for the wide spread of the disease?
| A．Its resistance to global warming. |
| B．Its ability to pass on the virus frequently. |
| C．Its outbreaks in cities with large populations. |
| D．Its ability to defend itself and resist new drugs. |
It can be inferred from the passage that___.
| A．no drugs have been found to treat the disease |
| B．the alternative treatment is not easily available to most people |
| C．malaria has developed its ability to resist parasites |
| D．nobody knows what will be the drug to treat the disease |
Which of the following questions has NOT been discussed in the passage?
| A．How can we know one is suffering from malaria? |
| B．How many people are killed by malaria each year? |
| C．Why are there so many people suffering from malaria7 |
| D．What has been done to keep people unaffected for long7 |
