New technology that can “ see ” through clothing and detect what ’ s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places.
The Thru Vision T5000 camera picks up Terahertz rays ，or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving subjects without showing any body detail.
While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it.
The technology develops from British astronomers ’ work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place.
For privacy concerns，Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. ” It's almost a shining light bulb(灯泡）.“ Beattie said. "You don' t see the detail that people might be concerned about. “ In London' s busy Piccadilly Circus—which is already filled with closed -circuit surveillance (监视）cameras— reaction to the new technology was mixed. Some said the camera was going too far and violating privacy，but others said they are willing to put safety before privacy concerns. “ There ’ s surveillance everywhere anyway, “ said one commuter. “I don' t think it’ s much of a difference. I don' t care that they can see through me because they can see me anyway.“
Some experts said the privacy violation of the camera was not worth the benefit. “ What we should consider is how much we want to lose our privacy in order to obtain a sort of national security，” said David Murakami Wood，director of the Surveillance Studies network，which deals with surveillance and privacy problems. “ In most cases this isn' t real security—it ’ s a sense of safety that has very little real effect. ”.

I sat at my seat waiting for the school paper to be passed around. I waited anxiously, knowing that once I received it I would know how good a writer I really am.
When the paper arrived at my classroom, I nearly knocked down five of my classmates to get to the first paper. With a school paper in my hands, I returned to my seat. About a month earlier, I had handed in one of, what I believed to be, my best stories. I named it Symbol of Success. The head of the English Department at my school, Professor Cullen had said that she would include some reviews of students’ stories in the latest school paper. Professor Cullen was known for her rough criticism. Impressing her was very hard but I wanted to be the first to do so.
I sat at the edge of my seat as I read through the other story reviews. There wasn’t one story that got more than three stars .I became calm and wasn’t anxious to know my review. It was long after that I heard someone shout out “Five stars?! Seriously!” from behind me. I turned around and saw the shocked expression of Gene’s face, “Peter, your story got five stars!” I couldn’t believe what I was hearing. I turned my attention back to my story and saw the five stars at the end of the review that I had not read yet. I looked through the review written by Professor Cullen. She wrote that I had a gift for story writing.
I was proud that I achieved what I thought was impossible .For so long I believed I wasn’t as good as I thought I was and that my talent was not enough to cover up my lack of wring skills .But this review proved that I was truly a good writer and that there was a future ahead of me in the field of fiction writing.

Nowadays, there’s a lot of debate about single sex education since it has begun to regain its popularity recently. According to long term studies of children from around the world, students achieve more and learn better in single sex schools.
An Australian study of 270,000 students found that both boys and girls performed much higher on standardized(标准化) tests when they attended separate schools. During an experiment in Virginia in 1995, 100 eighth graders were separated just for math and science courses. Almost immediately, the girls began to achieve more, become more confident and take part more often in class activities.
In 2001, a British study concluded that nearly every girl regardless of (不论) her ability or socio-economic status performed better in single sex classrooms than co-ed ones. The study of 2,954 high schools and 979 primary schools showed that while boys at the lowest levels in study improved the most in single sex schools, single sex education was particularly beneficial (有益的) to girls. Every one of the top 50 private elementary schools and top 20 private high schools in Britain are single sex schools.
Girls became more confident in themselves as students and earned higher scores on their College Board and Advanced Placement examinations. A quarter of the female members of the US Congress and one-third of all female members of Fortune 100 boards graduated from all-women’s colleges.
While the statistics are not as dramatic for boys, however, boys tend to soften their competitive edge and become more cooperative in a single sex setting. They can just be boys and not worry about what the girls might think.
Single sex education has a pleasant way of encouraging children to be fearless, to be curious, to be enthusiastic --- in short, to just be themselves. Children are subjected (屈从于) to pressures from every quarter to become adults before they are ready to do so. They grow up too quickly. Why not let them be children for a few more years? Single sex education with its gentler, more controlled social atmosphere is just the right answer for many children.With the experiment in Virginia in 1995, the writer wants to show that.
| A．single sex education has become popular in recent years |
| B．the effect of single sex education on girls is immediate |

I have this old clock that belonged to my mom. My dad gave it to me years ago after mom passed away.
I have mixed feelings about having the clock. I love it because it was my mom’s, but it also holds some bad memories.
You see, it chimes. It counts out the hour and rings once on the half hour. Or at least it used to. Now you never know what number it will ring.
When my mother was at home dying from cancer, she asked for the clock to be unplugged. Hearing the hours count down really angered and frightened her.
Mom passed away. I decided I wanted to get the clock fixed so I could remember the good hours we had with her.
I took it to a local clock shop the other day.
“I know this has no particular value as a clock, but it was my mom’s and I need to get it fixed,” I said to the shop owner.
I went on to describe the problem.
“We get a lot of these in,” he told me. “Here’s what I do. We remove the clock works (机件) and replace it with a battery-operated movement (机芯) that chimes electronically,” he told me.
“You can’t fix this?”
“No, we don’t have the time nor the parts.”
I thanked him and went home. I called a few other places and was told the same thing.
“How incredibly sad,” I told the last one disappointedly.
How incredibly sad that we have become a society that replaces craftsmanship with convenience and easy fixes. We copy the original instead of creating something new. We duplicate (复制); we don’t originate (发明).
Sadly, the same goes for our attitude to life itself.
Each of us is an original, one of a kind. But we find it so much easier to copy another style than to develop our own.
We are wannabes (崇拜别人的人) rather than hey-world-look-at-mes.
We fail to see the real value in who we are, so we spend our lives trying to be someone else. Why did the author decide to get the clock fixed?
| A．Because it was a really old and valuable clock. |
| B．Because it was the only thing that her mother had left her. |
| C．Because it brought her memories of being with her mother. |
| D．Because it left the author with mixed feelings. |
What did the clock shop owners tell the author?
| A．The parts that the clock needed were electronic. |
| B．It would cost a lot to repair the clock. |
| C．They had never repaired a clock like this before. |
| D．They could only make the clock electronic. |
The author intends to ________.
| A．criticize the irresponsible clock shop owners |
| B．criticize people who do not value things with a history |
| C．criticize people who do not have a creative attitude toward life |
| D．criticize people’s ignorance of traditional craftsmanship |
Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you can find in any neighborhood, these two loved each other and played together so often that they had worn a path through the grass of the field between their houses.
One evening, Brownie’s family noticed that Brownie hadn’t returned home. They went looking for him with no success. Brownie didn’t show up the next day, and, although they made their efforts to find him, by the next week he was still missing, Curiously, Spotty showed up at Brownie’s house alone, barking and jumping. Busy with their own lives, they paid no attention to the nervous little neighbor dog.
Finally, one morning Spotty refused to take “no” for an answer. Ted, Brownie’s owner, was continuously disturbed by the angry, determined little dog. Spotty followed Ted about, barking all the time, then rushing toward a nearby empty lot and back, as if to say, “Follow me! It’s urgent!”
Eventually, Ted followed Spotty across the empty lot as Spotty stopped to race back and barked encouragingly. The little dog led the man to a deserted spot a half mile from the house. There Ted found his beloved Brownie alive, one of his legs crushed in a steel trap (圈套). Frightened, Ted now wished he had taken Spotty’s earlier appeals seriously.

About this time every year, I get very nostalgic(怀旧的). Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors.
It is hard for me to accept that many of my wonderful neighbors are growing old and won’t be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever.
The “comings and goings” of the younger generation of my street are now mostly “goings” as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world was the gutter at the end of the street. We got pleasure from playing night games or from a breathtaking ride on a tricycle. Things are different now, as my friends become adults and move on. Children who rode tricycles now drive cars. The kids who once played with me now have new interests and values as they go their separate ways. Some have gone away to college like me, a few got married, two went into the army, and one went to prison. Watching all these people grow up and go away makes me long for the good old days.
Perhaps the biggest change on my street is the fact that the city is going to turn my precious hill into several lots for new homes. For sixteen years, the view out of my kitchen window has been a view of that hill. The hill was a fundamental part of my childhood life; it was the hub of social activity for the children of my street. We spent hours there building forts, sledding, and playing tag. The view out of my kitchen window now is very different; it is one of tractors and dump trucks tearing up the hill. When the hill goes, the neighborhood will not be the same. It is a piece of my childhood. It is a visual reminder of being a kid. Without the hill, my street will be just another pea in the pod.
There was a time when my street was my world, and I thought my world would never change. But something happened. People grow up, and people grow old. Places changes, and with the change comes the heartache of knowing I can never go back to the times I loved. In a year or so, I will be gone just like many of my neighbors. I will always look back to my years as a child, but the place I remember will not be the silent street whose peace is interrupted by the sounds of construction. It will be the happy, noisy, somewhat strange, but wonderful street I knew as a child.The writer calls up the memory of the street _____________.
