Targeting teens
But using the Web also makes teens a target. Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life.
As Mary learned, not everyone on the Internet is who he or she says they are. Adults will sometimes pose as other teens, posting fake photos and nice messages to gain trust. They use their fake identity to access the personal information of others, such as home address, phone number, or school name.
"That's not the most common scenario", says David Finkelhor, a sociology professor at the University of New Hampshire. "Only 3 percent of teens aged 10 to 18 who use the Internet report being asked to meet offline. But the danger is real.
Safety measures
Mary's My Space profile is set to "private", which means that only the people she adds under the "friend" category can access her page. She also doesn't have any pictures of herself on her site. The only self-identifying material she has posted is her name, grade, and a list of hobbies.
"People can only add me if they know my last name or my e-mail, "Mary says. " I don't want random people to see my profile. I just go online to talk to my friends."
Stay safe and have fun online
Experts say almost 90 percent of U.S. Teens are online. But not everyone knows how to surf the Web in a smart way. With these tips, you can have fun, stay safe, and avoid embarrassment!
Pick a safe password. Make sure your password is something that other people won't be able to guess. Use numbers in between letters. "spar123ky" is better than "sparky 123."
Pick a safe username. Make sure yours doesn't say too much about you, "Happygirl13" is better than "AliceWaters13." Don't include your name, age, or where you are from. Never tell a stranger your name, school, address, age, birthday, phone number, or friends' names.
56．Who is most likely to be a victim online?
A．A liar. B．A teenager. C．A stranger. D．An honest person.
57．In Mary's opinion, _________.
A．one shouldn't trust everyone online B．one shouldn't trust anyone online

If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can’t hear what their teachers are saying. And it’s not because these students are goofing off. Often, it’s the room’s fault. Building architecture and building design can create echo(回聲)-filled classrooms that make hearing difficult.
Children with hearing impairments（損傷）suffer most from noisy classrooms. They sometimes can’t hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking.
Even kids with normal hearing have a harder time in the classroom when there’s too much noise. Younger children in particular have trouble separating important sounds – like a teacher’s voice – from background noise. Kids with learning disabilities and speech impediments（障礙）and kids for whom English is a second language also have a harder time learning in noisy situations.
In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They’re also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better.
“It’s so obvious that we should have quiet rooms that allow for access to the lesson,” says Dan Ostergren, a hearing scientist. “Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?”
【小題1】 The underlined part “goofing off” in the first paragraph can be replaced by “ ”.
| A．lazy | B．intelligent | C．sleepy | D．foolish |
| A．Children with learning disabilities. | B．Children with hearing impairments. |
| C．Children with speech impediments. | D．Children with normal hearing. |
| A．Quiet classrooms are suitable for kids to have discussions. |
| B．Quiet classrooms help kids recover from hearing impairments. |
| C．Kids can become smarter after hearing lessons better. |
| D．Kids can’t separate sounds of air-conditioners and pipes. |
| A．Noisy classrooms | B．Classroom design |
| C．The sense of hearing | D．Disabled kids |

BEIJING – Alarmed by the overreaching ambitions of many Chinese provinces to grow at all cost, China’s top economic chief is calling on officials to calm down and spare a thought for the environment.
Zhang Ping, who heads China’s National Development and Reform Commission, the central economic planning agency, said only five or six of China’s 30 provinces are targeting annual economic growth of 8 percent or 9 percent.
The remaining provinces are aiming for growth rates of more than 10 percent this year, with some wanting to double economic output in the coming five years.
“China has a planned energy supply of about 4 billion cubic tons of coal equivalent (等量的) for the next five years, and this is not enough to meet demands for economic growth to double,” he was quoted as saying on the news portal Sina. com.
Beijing is increasingly concerned with the ambitions of Chinese provinces across the country to chase high growth despite the central government’s urgent request for a more moderate and sustainable (可持續(xù)的) pace of expansion.
Years of rapid economic growth have taken a toll on China’s environment, with Beijing trying to remove some of the damage now. It has an annual growth target of 7 percent for the next five years, well down from last year’s 10 percent.
Zhang said Beijing has asked local governments to take into account the supply of “energy, environment, water and land” to set more reasonable growth target.
【小題1】Which of the following statements is TRUE according to the passage?
| A．The supply of the coal in China is not sufficient for the next five years. |
| B．Zhang Ping is an expert and economic chief from www. sina.com. |
| C．Few Chinese provinces are aiming for economic growth rates of less than 10%. |
| D．Many Chinese provinces are alarmed by Beijing. |
| A．improved | B．done damage to | C．restored | D．a(chǎn)ttached importance to |
| A．China’s economy is increasing at a fast speed. |
| B．China’s top chief lays more emphasis on the environment |
| C．economic high growth should go hand in hand with environment concern. |
| D．a(chǎn)ll Chinese provinces should slow down their economic growth rates |
| A．Economic Development | B．Energy Supply |
| C．Environment | D．Sustainable Development |

Europe’s deadly outbreak of a rare form of E. coli bacteria (大腸桿菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(腸) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
1.What is the main topic of the text?
A. Bacteria.????????????? B. A high-tech scanner.????????????? ? C. A camera????????????? D. Food safety.
2.E. coli bacteria ______.
A. broke out all over the world????????????? ????????????? ????????????? ? B. comes from soil or animal waste
C. is extremely harmful to health????????????? ????????????? ????????????? ? D. does not cause illness
3.The high-tech scanner ______.
A. can help to sort out different fruits
B. make the produce appeal to shoppers
C. can only capture images of the whole apple
D. can identify the presence of contaminants
4.What can be inferred from the text?
A. The scanner needs to be improved.
B. The scanner will be available in the next several years.
C. Moon Kim is unwilling to develop the scanner.
D. The scanner is connected to a sorting machine.
