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

Greenspace facilities (设施) are contributing to an important degree to the quality of the city environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present it is generally accepted, although more as a self-proved statement than on the base of a closely reasoned scientific proof. Recognizing the importance of greenspaces in the city environment is a first step on the right way, this does not mean, however, that enough details are known about the functions of greenspace in towns and about the way in which people are using these spaces. As to this subject I shall within the scope (范围) of this lecture, enter into one aspect only, namely the recreative function of greenspace facilities.
The theoretical separation of living, working, traffic and recreation (娱乐) which for many years has been used in town and country planning, has in my opinion resulted in more attention for forms of recreation far from home, while there was relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home. We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working, is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the street door of the house. The city environment has to offer as many recreation activities as possible, and the design of these has to be such that more required activities can also have recreative aspect.
The very best standard of living is nothing if it is not possible to take a pleasant walk in the district, if the children cannot be allowed to play in the streets because the risks of traffic are too great, if during shopping you can nowhere find a spot for enjoying for a moment the nice weather, in short, if you only feel yourself at home after the street door of your house is closed after you.
1.The importance of greenspaces in the city environment _____.
A. is still unknown
B. is paid little attention to
C. is accepted on the base of scientific proof
D. has been recognized
2.For many years town and country planning has _____.
A. brought living areas and places of entertainment close together
B. separated recreation facilities far from home
C. improved recreative possibilities in the neighborhood
D. enabled people to reach the best standard of living
3.According to the author, greenspaces should be designed _____.
A. to reduce the number of recreative activities
B. to attract more and more people
C. for people to use more conveniently
D. for people to do recreative activities at the street door of the house
4.The main idea of this passage is that _____.
A. attention must be paid to the improvement of recreation
B. greenspace facilities should be used better to improve the quality of life
C. the city environment is providing more recreative activities
D. we should try our best to raise our living standard

It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong. Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school?
During adolescence, the body goes through many changes and these include a shift in sleep patterns. Researchers from MIT have been tracking the body’s need for sleep in teenagers. They found that though adolescents need as much as 9.5 hours of sleep a day, they get to bed later and later with each passing year. In fact, the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20! So by the time a 10yearold who sleeps at 8 pm grows to be 17 or 18, his body naturally wants to stay up till 10：30 pm or 11 pm.
According to researchers, this is because of a hormone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland — a tiny structure deep inside the brain. Melatonin regulates the body’s natural daynight rhythms. It causes a person to become sleepy by lowering his body’s core temperature. In teens, melatonin is secreted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Likewise, the effect of melatonin continues until much later in the morning, making it hard for them to wake up early.
A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep, important body functions and brain activities happen. So how can teenagers get their sleep enough? The American Academy of Pediatrics (AAP) recommends that middle and high schools should start later — not before 8：30 am. This should give teens some more time to sleep at night.
1.From Paragraph 2, we can learn that if you sleep late, the next day you should ________.
A. stay sharp B. skip breakfast
C. get up late D. stay up late
2.What does the underlined word “this” in Paragraph 3 refer to?
A. The students want to stay up.
B. The shifts of the sleep cycle.
C. The pineal gland secretes melatonin.
D. The adolescents sleep late.
3.The teens go to sleep later than before because ________.
A. melatonin is secreted much later
B. melatonin regulates the sleep time
C. they sleep a lot in the daytime
D. they need to finish their homework
4.According to AAP’s recommendation, middle and high schools should ________.
A. let teens sleep in the day B. let the students be active
C. delay the start time D. start later at 8 am
