People, whose desk space is well ventilated (使空气流通) with below average indoor pollution and carbon dioxide levels, showed more ability to think, understand, remember and learn, according to a new study. Researchers at Harvard claim that working in a green office can help increase the brainpower. It's clear that the indoor air quality can have a great impact on the performance of workers.
Researchers looked at the decision making abilities of 24 participants (参与者), who were exposed to different indoor working conditions over six days. The data showed that those with higher levels of pollutants were less able to finish the work. Participants scored an average of 61 percent higher while working in buildings with the low pollution level, compared with those working in the conventional buildings.
The participants were tested on everything from the basic task to crisis (危机) response and information seeking. When low carbon dioxide levels were combined with lower level of pollutants in buildings, scores were 101 percent higher than in buildings with the same decoration and furniture, which researchers said was important. All the time, it is not typically thought of as a direct indoor pollutant.
Dr Joseph Allen, director of the healthy buildings program at the Centre for Health and Global Environment, notes the air quality in the office is an area that has been largely ignored. Fortunately, the research results from Harvard has sounded the alarm in time. “We spend 90 percent of our time indoors, yet indoor environment and its impact on health and productivity are often an afterthought，” he said.
It has turned out that even the modest improvement to indoor air quality may contribute to the decision making performance of workers. British research has found that having plants in the workplace can increase productivity by 15 percent by making workers more physically and emotionally involved in their jobs.
1．What's the new finding from Harvard
A．It's necessary to paint the office green.
B．Fresh air can improve work efficiency.
C．Air quality in the office is usually poor.
D．People make more mistakes in big offices.
2．What does the underlined word “it” in Paragraph 3 refer to
A．Furniture. B．Decoration.
C．Carbon dioxide. D．The level of pollutants.
3．What's the attitude of Dr Joseph Allen to the research results from Harvard
A．Critical. B．Positive.
C．Doubtful. D．Unconcerned.
4．We can infer from the last paragraph that ________.
A．people should reduce time spent indoors
B．working conditions decide one's working ability
C．British research is opposite to Harvard study
D．plants in the office can help people work better

In your life, sometimes you may be asked to speak in front of a large group of people. Although it sounds a little scary, even those with stage fright can speak successfully to the group with adequate preparation.
·Practice your speech before the big day.
__1__ If possible, practice the speech in front of a friend or family member to get used to saying it to real people. If you feel you must have note cards, limit the amount to about three cards. This will force you to keep your speech concise and help you keep your eyes focused on your audience.
·Remember why you've been invited to speak.
If you're battling fear over speaking to a large group of people, keep your mind on the fact that you were selected for this important role. The speech organizers must have seen something valuable in you or your expertise. __2__
·Remember that fear of public speaking is very common.
__3__ Most of the people in the audience would be feeling the same fear and stress that you do in your position. Knowing this may make you feel better.

·Keep eye contact with the crowd.
__5__ Pick one person in each section and look at him while you're speaking. After each important point in your speech, switch your focus to another section. When you focus only on one person at a time, the size of the crowd isn't as frightening.
A．A good memory is really helpful.
B．Show appreciation to your audience.
C．Mention your audience in your speech.
D．The more you have it memorized, the better.
E．In fact, it's normal to feel nervous or stressed out before a big speech.
