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. ”.

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine（可可碱）, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a nerve activity(神经活动), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.According to Professor Barnes, theobromine ______.
| A．cannot be as effective as codeine |
| B．can be harmful to people’s health |
| C．cannot be separated from chocolate |
| D．can be a more effective cure for coughs |
What was used in the experiment to cause coughing?
| A．Theobromine. | B．Codeine. | C．Capsaicin. | D．Placebo. |
We learn from the text that volunteers in the experiment _____.
| A．were patients with bad coughs |
| B．were divided into the three groups |
| C．received standard treatments |
| D．suffered little side effects |
Which of the following would be the best title for the text?
| A．Codeine: A New Medicine |
| B．Chocolate May Cure Coughs |
| C．Cough Treatment: A Hard Case |

How to Be a Winner
Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes(糖尿病). Believing my career was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it ---the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn't finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success----you can’t follow a career in any field without being well-organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best

“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological tool”What does Sir Steven Redgrave mainly talk about?

I once had my Chinese MBA students brainstorming on “two-hour business plans”. I separated them into six groups and gave them an example: a restaurant chain. The more original their idea, the better, I said. Finally, five of the six groups presented plans for restaurant chains. The sixth suggested a catering service. Though I admitted the time limit had been difficult, I expressed my disappointment.
My students were middle managers, financial analysts and financiers from state-owned and global companies. They were not without talent or opinions, but they had been shaped by an educational system that rarely stressed or rewarded critical thinking or inventiveness. The scene I just described came in different forms during my two years’ teaching at the school. Papers were often copied from the Web and the Harvard Business Review. Case study debates were written up and just memorized. Students frequently said that copying is a better business strategy(策略), better than inventing and creating.
In China, every product you can imagine has been made and sold. But there are so few well developed marketing and management minds that it will be a long time before most people in the world can name a Chinese brand.
With this problem in mind, co-operation with institutions like Yale and MIT have been started . And then there’s the “thousand talent program”: this new government program is intended to improve technological modernization(现代化). It can attract top foreign trained scientists to the mainland with big money. But there are worries about China’s research environment.
At last, for China, becoming a major world creator is not just about co-operation with top Western universities. Nor is it about gathering a group of well-educated people and telling them to think creatively. It’s about offering a rich learning environment for young minds. It’s not that simple.Why does the author feel disappointed at his students?
| A．Because there is one group presenting a catering service. |
| B．Because the six groups made projects for restaurant chains. |
| C．Because all the students copied a case for the difficult topic. |
| D．Because the students’ ideas were lacking in creativeness. |
We can infer from the passage that ________.
| A．China can make and sell any product all over the world |
| B．high pay may not solve the problem of China’s research environment |
| C．cooperation with institutions has been set up to make a Chinese brand |
| D．the new government program are aimed at encouraging imagination |
Which is the best title of the passage?
| A．Look for a New Way of Learning. |
| B．Reward Creative Thinking. |
| C．How to Become a Creator. |
| D．Establish a technical Environment. |
People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word“mouth”.
For example, if you say bad things about a person, the person might protest and say“Do not bad mouth me. ”Sometimes, people say something to a friend or family member that they later regret because it hurts that person’s feelings. Or they tell the person something they were not supposed to tell. The speaker might say:“I really put my foot in my mouth this time. ”If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing.
Another situation is when someone falsely claims another person said something, the other person might protest,“I did not say that . Do not put words in my mouth. ”
