A major source of teen stress is school exams, and test anxiety is not uncommon. When you recognize your teen is under stress, how can parents help your teen stay calm before an exam?
Be involved. Parents need to be involved in their teen’s work.  1 _  What they look for is your presence — to talk, to cry, or simply to sit with them quietly. Communicate openly with your teen. Encourage your teen to express his worries and fears, but don’t let them focus on those fears.
Help them get organized.   2   Together, you and your teen can work out a time-table in which he can study for what he knows will be on the test.
Provide a calm setting. Help your teen set up a quiet place to study and protect his privacy. Give them a nutritious diet. It is important for your teen to eat a healthy, balanced diet during exam times to focus and do his best.   3   If this happens, encourage your teen to eat light meals or sandwiches. A healthy diet, rather than junk food, is best for reducing stress.
  4   Persuade your teenager to get some sleep and /or do something active when he needs a real break from studying. Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance his time so that he will feel comfortable taking time out from studying to spend time with friends or rest.
Show a positive attitude.   5   Your panic, anxiety and blame contribute to your teen’s pressure. Make your teen feel accepted and valued for his efforts. Most importantly, reassure your teen that things will be all right, no matter what the results are.

Boxing games are truly widely supported by a lot of people over the world . The sport involves two people fighting with each other inside a ring with a referee making sure that the fight goes on smoothly. The fighters have to be of the same weight to be able to fight and they make use of their fists according to the rules of competition.
There are three ways in winning the game. First, you have to knock out the challenger. Secondly, there is the technical knockout (击倒). This usually happens when the rival is seriously hurt and unable to carry on and defend himself. Thirdly, each boxer gets on with the fight until the last round is over and done with and the winner is judged according to the scores he gets.
The first boxing champion was James Figg who came from England. It was in 1719 that the word "boxing" was known. The sport then was completely different from what you are used to seeing and observing nowadays. In 1743 Jack Broughton, a boxing title holder, was responsible for coming up with the rules and regulations to make the fight more manageable.
Under these rules, a boxer who falls and does not fight after 30 seconds has elapsed is declared the loser and any fighter is prevented from hitting his opponent when he is already down. Broughton was also the one who created the mufflers -- a kind of gloves with padding which were used during presentations and training.
Today, the sport has a total of 12 rounds with three minutes playing time for each round. Boxers are given a minute for them to rest or for consultation with their respective coaches. A referee has the responsibility of making sure that the boxers carry on with the fight according to the rules of the sport. The judges have the task of evaluating each fighter and give the fighter scores according to their punches(拳法).

___52___. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point in the city, floodedd about nine times a year, Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu’s rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it to rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciersmelt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10－25 cm in the last 100 years.
___53___. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO₂. This adds to the power of the greenhouse effect, making the planet even warmer.

A. The spreading of tea

B. The history of tea growing

C. Changes of tastes for drinks

D. Reducing cancer risks

E. The plant Camellia sinensis

F. A woman’s opinion of tea

1.________________

Americans are far more knowledgeable about drinks than they were 20 years ago. Witness the Starbucks revolution and you’ll know where the trend goes. Now, encouraged by recent studies suggesting that it can cut the risk of cancer and heart disease and slow the aging process, tea is enjoying a similar change. Enough fashionable tea houses are springing up to make even longtime coffee drinkers consider switching drinks.

2.________________

Tea is available in more places than ever. The Tea Association of the United States reports that from 1990 to 1999, annual sales of the drink grew to $4.6 billion from $1.8 billion. “Green tea is seen by consumers as a ‘functional food’” — delivering health benefits beyond food itself, says Vierhile.

3._______________

Recently published studies point out that only teas that come from the leaves of the plant Camellia sinensis have been shown to contain health benefits. Other herbal teas may taste good, yet they do little more than warm up the drinker. But for Camellia sinensis, the evidence is powerful. In a 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent compared with non-tea drinkers, and other studies have suggested that the antioxidants (抗氧化剂) in these so-called real teas can also prevent cancer.

4.________________

One such antioxidant in green tea is ECGC, a compound 20 times as powerful as vitamin E and 200 times as powerful as vitamin C. “When people ask me for something good and cheap they can do to reduce their cancer risk, I tell them to drink real tea,” says Mitchell Gaynor, director of medical oncology at New York City’s Strang-Cornell Cancer Prevention Center.

5.________________

Among those inspired to become a green-tea drinker is Tess Ghilaga, a New York writer who took it up after seeking advice from a nutritionist six years ago. “I’ve never been a coffee drinker,” says Ghilaga, 33. “She told me to start drinking green tea for the antioxidant qualities.” Now Ghilaga and her husband habitually make tea — they order theirs from InPursuitofTea.com, an Internet tea company. And although tea contains about half the amount of caffeine in a cup of coffee, “you still get such a kick from it,” says Ghilaga.
