Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.

Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to “relieve anxiety, improve alertness(機(jī)敏性) and reduce stress among individuals in a laboratory setting.”

Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing “a group of ‘multi-tasking’ activities.” Doesn’t it sound like the situation in the office?

Here’s a summary of some of the study’s findings:

Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress.

Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress.

Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities.

Although these aren’t major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol(皮質(zhì)醇)—a steroid(類固醇) hormone that is released in response to stress in your system.

A few words of advice before you reach for the gum: don’t crack your gum, and be sure to chew it with your mouth closed. In fact, I’d say keep the gum out of meetings, because it really looks impolite to others around you.

1.From the study in the text we know that_________________.

A. gum chewers may lack alertness

B. gum chewers tend to be less stressed

C. gum chewers can finish many jobs perfectly

D. gum chewers can reduce their anger easily

2.How does gum work to reduce stress according to the text?

A. It works by improving alertness.

B. It works by allowing a 10-minute walk.

C. It works by reducing one’s level of cortisol.

D. It works by being chewed in a laboratory setting.

3.Which one may the author probably agree with?

A. People can crack gum freely when meeting friends.

B. People should be careful when chewing gum at home.

C. People should chew gum with their mouths closed in a meeting.

D. It is impolite to chew gum in a meeting with people around you.

4.What does the text mainly talk about?

A. How to chew gum.

B. How to relieve stress.

C. Chewing gum can relieve stress.

D. Why people love chewing gum.

A teenager who is preparing to go to high school has probably heard all kinds of different things about high school freshmen from his parents , fiends , or old brothers and sisters. The change from middle school to high school can seem like a frightening experience for teens going into high school , but it is not always so hard as it may seem. Usually , middle school students can get used to high school life within a few months of their freshman year. A few tips for high school freshmen are as follows.

Grades are important . While it is important for a student to try to do his best in school , the grades that he gets in high school are even more important , since they are what colleges will look like when considering his application (申請(qǐng))for their school .

Classes . The classes a freshman takes throughout his whole high school can help them a lot when he gets ready to go to college or look for a job . Some special classes allow students to get college credits（學(xué)分）while they are still in high school in some countries . Most high school classes will have more homework than middle school classes and this can be a hard adjustment (適應(yīng)) at first .

Being prepared . Middle school classes might not request students to prepare very much before they attend them . But high school teachers will expect students to get everything ready before the class begins .It is also important for students to study for tests and do all homework that is required during class.

Making good choices. Most high school students have more freedom than middle school students, but what a student does with this freedom is very important to his future life for many years after high school is over. Peer pressure（同齡人壓力）, while it can be good sometimes, is often a problem with younger teens .It is important for a teen to make good choices throughout his high school career so that he can be successful later on in his life .

High school is a memorable experience for teenagers .They should not be afraid of becoming a freshmen . After studying for a period of time , they will surely enjoy it.

I'd like to tell you something more about the problem of pollution we

are facing to. As we know, the factory besides our school gives off heavy

smoke all day long. Very loud voices hurt our ears. Rubbish and waste

are thrown here or there. It also sends out polluting water and poisonous

gas. All this has made a great harm to the health and study of the teachers

and students. But with time goes on, a little has been done to change the

situation. I don't think we could study well unless the problem is solved.

We do hope you'll help and support us.
