At a primary school in a small town in the east of South Carolina, second-grade teachers Garneau and Lynne are convinced that separating elementary-age boys and girls produces immediate academic improvement in both genders（性別）．

    David Chadwell, South Carolina’s expert of single gender education says, “Boys and girls learn, hear and respond to their surroundings differently．We can teach boys and girls based on what we now know．”

    Male and female eyes are not organized in the same way, he explains．The organization of the male eye makes it sensitive to motion and direction．“Boys understand the world as objects moving through space,” he says．

    The male eye is also drawn to cooler colors like silver and black．It’s no accident that boys tend to create pictures of moving objects instead of drawing the happy colorful family, like girls do in their class．

    The female eye, on the other hand, is drawn to warmer colors like red, yellow and orange．To attract girls, Chadwell says, the teacher doesn’t need to move as much as in boy’s class．Using descriptive phrases and lots of colors in presentations or on the blackboard gets their attention．

    Boys and girls also hear differently．“When someone speaks in a loud tone, girls understand it as yelling,” Chadwell says．“They think you’re mad and can shut down．” Girls are more sensitive to sounds．He advises girls’ teachers to watch the tone of their voices．Boys’ teachers should sound more forceful, even excited．

    A boy’s nervous system causes him to be more cautious when he is standing, moving, and the room temperature is around 69 degrees Fahrenheit．Stress in boys, he says, tends to increase blood flow to their brains, a process that helps them stay focused．Girls are more focused when seated in a warmer room around 75 degrees Fahrenheit．Girls also respond to stress differently．When exposed to threat and conflict, blood goes to their guts（腸道）, leaving them feeling nervous or anxious．

    These differences can be applied in the classroom, Chadwell adds．“Single gender programs are about making the best use of the learning．”

What is David Chadwell’s attitude toward separating elementary-age boys and girls while learning?

    A．Supportive   B．Worried  C．Concerned    D．Uninterested

To engage boy in a class, the teacher ______．

    A．must have a moving object in this hand    

    B．needs to wear clothes in warm color

    C．has to speak politely               

    D．had better move constantly while teaching

Which of the following shows the organization of the passage?

（ ??= Paragraph 1  ??= Paragraph 2  ??= Paragraph 3  …．．． ??= Paragraph 8 ）

   

Which of the following students is most likely to be focused?

    A．A boy sitting in a warm room B．A standing boy who is faced with stress

    C．A girl standing in a cold room   D．A girl who is facing a lot of pressure

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

     C．there are many liars online      D．a(chǎn)ll people online pretend to be others

58．One of the safety measures mentioned in the passage is that _________.

     A．one should not chat with strangers

     B．one should not post his or her photos online

     C．one should tell his parents about strange information

     D．one should keep his web as a secret

59．Why are numbers used when we pick a safe password?

     A．Numbers are easy to write.

     B．Using numbers are cool online.

     C．The safe password is more unlikely to be guessed.

     D．Numbers are popular online.

There is a new take on an old tale．It's the story of the three
little pigs and the big bad wolf that blew down a house made of
straw and one made of sticks．The only house left standing was
the one made of bricks．Now there is new evidence to suggest
that houses built with bales（捆）of straw can be very strong．
Pete Walker is a professor at the University of Bath in Britain．
He and a team of researchers there have built a house made out of straw bale and hemp（大麻） material．During the next twelve months the team will study die effectiveness of these materials in home building．Professor Walker says there are many good reasons for using straw．It's a relatively inexpensive renewable material that's quickly and easily available．Straw takes in carbon dioxide as it grows．So it can be seen as having no harmful effects the environment．And the straw bales walls are relatively thick and so all that straw provides very good thermal insulation．So we make buildings that require very little heating in winter or indeed very little cooling in summer．So they require very little additional energy．
David Lanfear owns an eco-friendly home building service in the United States called Bale on Bale Construction．He says he laughed when some friends first told him about houses built of straw．But after doing his own research, he learned that building with straw bales makes a lot of sense．He has now helped to build more than ten straw bale houses and says the building material is becoming more widely accepted．To build the houses, he fills a wood frame with tightly packed bales of straw．Next he coats the walls inside and out with layers of clay plaster．He says the common ideas about straw houses continue, including stories about the threat of fire．As a matter of fact, straw bale houses have done well when tested for fire resistance．And his builders use the same building methods as traditional builders to keep out rain．He says we use what we call good shoes and a good hat, and that would be a solid foundation and a really good roof．
68．According to the passage, Pete Walker ____．
A．is cooperating with David Lanfear in building houses
B．is pretty sure that straw is a good building material
C．is studying home building with his team at present
D．holds a different view of building materials from David Lanfear
69．If we live in houses built with bales of straw, we ____．
A．will be worried about the threat of fire
B．need to wear good shoes in severe weather
C．can reduce our household expense
D．should use a special method to keep out rain
70．In building straw houses, ____．
A．a(chǎn) solid foundation and a good roof are necessary
B．straw bales have to be tested for fire resistance
C．a(chǎn) wood frame of straw should be used as a good roof
D．builders should wear good shoes and a good hat
71．Which of the following is the best tide of the passage?
A．Houses Made of Straw
B．New Meaning Of an Old Tale
C．Pete Walker and David Lanfear
D．Solid Foundation and Good Roof

五.任務(wù)型閱讀（10分）

Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, powerlines and wi-fi (路由器) could be responsible for a range of illnesses, from rashes to brain tumours.

For example, Camilla Rees, 48, a former investment banker in the US, moved out of her apartment in San Francisco because of the radiation coming from next door. Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly. “I would wake up dizzy in the morning. I’d fall to the floor. I had to leave to escape that nightmare,” she said. Since then, she’s been on a campaign against low-level electromagnetic fields, or EMFs（低頻電磁場）.

And she’s not alone. Millions of people say they suffer from headaches, depression, nausea and rashes when they’re too close to cellphones or other sources of EMFs.

Although the World Health Organization has officially declared that EMFs seem to pose little threat, governments are still concerned. In fact, last April, the European Parliament called for countries to take steps to reduce exposure to EMFs. The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones. 

If these fears are reasonable, then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots.

Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the University at Albany, in New York, thinks there’s a greater than 95% chance that power lines can cause childhood leukemia. Also there’s a greater than 90% chance that cellphones can cause brain tumours.

But others believe these concerns are unreasonable paranoia (猜疑). Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don't have the evidence that there’s much danger.”

Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group.

According to Robert Park, a professor of physics at the University of Maryland in the US, the magnetic waves aren’t nearly powerful enough to break apart DNA, which is how known threats, such as UV rays and X-rays, cause cancer.

Perhaps it’s just psychological. Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome, which is a condition that’s considered to be psychological.

Whether EMFs are harmful or not, a break in the countryside, without the cellphone, would probably be good for all of us.

At a primary school Manning， Carolina， second-grade teacher David Chadwell believed that segregating(隔離) elementary-age boys and girls produces immediate academic improvement—in both genders. “Although this is a tendency， we can teach boys and girls based on what we now know.”

“They see differently. Literally，” he begins. Male and female eyes are not organized in the same way， he explains. The composition of the male eye makes it attuned(協(xié)調(diào)) to motion and direction. “Boys interpret the world as objects moving through space，” he says. “The teacher should move around the room constantly and be that object.”

The male eye is also drawn to cooler colors like silver， blue， black， grey， and brown. It’s no accident boys tend to create pictures of moving objects like spaceships， cars， and trucks in dark colors instead of drawing the happy colorful family， like girls in their class.

The female eye， on the other hand， is drawn to textures and colors. It’s also oriented toward warmer colors—reds， yellows， oranges—and visuals with more details， like faces. To engage girls， Chadwell says， the teacher doesn’t need to move as much， if at all. Girls work well in circles， facing each other. Using descriptive phrases and lots of color in overhead presentations or on the chalkboard gets their attention.

Boys and girls also hear differently. “When someone speaks in a loud tone， girls interpret it as yelling，” Chadwell says. “They think you’re mad and can shut down.” Girls have a more finely tuned aural structure； they can hear higher frequencies than boys and are more sensitive to sounds. He advises girls’ teachers to watch the tone of their voices. Boys’ teachers should sound matter of fact， even excited.

A boy’s autonomic nervous system causes them to be more alert when they’re standing， moving， and the room temperature is around 69 degrees. Stress in boys， he says， tends to increase blood flow to their brains， a process that helps them stay focused. This won’t work for girls， who are more focused seated in a warmer room around 75 degrees. Girls also respond to stress differently. When they are exposed to threat and confrontation， blood goes to their guts(內(nèi)臟)， leaving them feeling nervous or anxious.

“Boys will rise to a risk and tend to overestimate their abilities，” he says. “Teachers can help them by getting them to be more realistic about results. Girls at this age shy away from risk， which is exactly why lots of girls’ programs began in the private sector. Teachers can help them learn to take risks in an atmosphere where they feel confident about doing so.”
