The Haitian tsunami gave scientists a chance to find out how well vital and potentially life-saving warning systems were working.

       Noaa’s Pacific Marine Environmental Laboratory has developed a warning system that picks up signals of tsunamis directly from the sea-floor.

       It is called Dart-the Deep-ocean Assessment and Reporting of Tsunamis. If seismometers(地震仪) detect an earthquake, the Dart buoys（浮标） will determine what is happening to sea levels, and whether a big wave might be on the way. This information is then sent via satellite to a central location which can organize an alarm. Within 50 minutes of the Haiti earthquake, this system was able to issue an alarm to other countries in the Caribbean to say that a small tsunami had been caused to start, and that was unlikely to affect them.

       Dr Bernard said, “The first 30 minutes following the earthquake, we have to rely on education.” The critical aspects of this are: do you feel the earthquake; do you see the ocean draw down; and do you hear that loud roar? If so, you should run for higher ground.

      

 “But after the first few minutes, it’s crucial that we have the technology—the measurements to avoid unnecessary evacuation(疏散撤离)and tell people when it is safe to return.” Right now, there are 50 of these Dart buoys all over the globe—four of which are in the Caribbean.

Dr Bernard says that, with 75 to 100 buoys worldwide, this system could provide global tsunami warnings within one hour.

 “That’s for everywhere we know that tsunamis have happened. If we wanted to go to half an hour detection, we could probably double or multiply by four times that number,” he said.

       “In some countries, including Haiti, there may not be enough resources to support a specific tsunami warning centre for something that happens so infrequently.”

       He said that this system was relatively inexpensive to fix and operate.

       “To get it down to an hour for everywhere affected would cost $50m initial investment and then 10% of that to maintain it,” he said.

       “That’s not a terribly expensive system considering the potential savings of lives.”

One of the most fascinating things about television is the size of the audience. A novel can be on the “bestseller” lists with a sale of up to 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well-known overnight.

  This is the principle behind “quiz” or “game” shows, which put ordinary people on TV to play a game for prizes and money. A quiz show can make anyone a star, and it can give away thousands of dollars. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show’s producers, who were pulling the strings, gave the answers to the most popular competitors in advance. Why? Because if the audience didn’t like the person who won the game, they turned the show off. The result of this cheating was a huge scandal(丑闻). Based on the show off, a movie titled “Quiz Show” is on 40 years later.

  Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren’t taken seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating(羞辱) them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.

What is the most important thing as to television?

  A. How many viewers they can attract     B. Becoming the bestseller on the list

  C. How much money can be given away  D. The number of people attending shows

What does the underlined part “pulling the strings” probably mean?

   A. Planning the shows with effort            B. Drawing the curtain on the stage

C. Controlling the result secretly         D. Playing “quiz” or “game” openly

Charles Van Doren stopped his career as a television personality because ________.

   A. he had earned enough wealth and fame.  B. one of the competitors had told the truth

   C. the film “Quiz Show” was being shown 

D. his frequent appearance had bored the audience

It can be inferred from the passage that _______.

A. TV Game Shows are more popular than before.

   B. the scandal was not made known until 40 years later

 C. getting money is the only purpose of people taking part in shows

 D. people can make themselves famous by taking part in shows

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 her 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 she can study for what she 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 her 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 she needs a real break from studying. Making time for relaxation，fun， and exercise are all important in reducing stress. Help your teen balance her time so that she 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 her efforts. Most importantly，reassure your teen that things will be all right，no matter what the results are.

A．A parent’s attitude will dictate their teen’s emotions.

B．Exam stress can make some teens lose their appetite.

C．They will only make the situation worse.

D．Encourage your teen to relax.

E. The best thing is simply to listen.

F. Help your teen think about what she has to study and plan accordingly.

G. Your teen may also make negative comments about themselves.

We have proof that you become what you eat. When you know the effects of different types of food, you can use your knowledge well and eat what you want to become.
Food has an impact on our physical and mental health. Have you ever heard any of the following advice?
Lettuce (莴苣) or milk can make you sleepy.
To stop feeling sleepy you should eat peanuts or dried fish.
Everyone has their own advice to give, which they have read about or have been told by older relatives. Some of these pieces of advice seem to contradict each other.
Eating chocolate makes you fat and gives you spots.
Chocolate contains the essential minerals: iron and magnesium (镁).
What we need to figure out is what type of chocolate to eat to get the benefits and how much of it to eat. We can do this by reading the list of ingredients (原料) on the chocolate bar package. Exactly how much real chocolate is in there? And how much of that do we need to eat to get the benefits of the minerals it contains?
Future restaurants might be named after the physical or mental state they hope to create. Their menus will list the benefits of each dish and drink. Some restaurants have already started this concept, and list the nutritional (营养的) content of their dishes on the menus.
Let’s take the restaurant “Winners” as an example. Their menu would list dishes specifically designed to help you win sports competitions. Or you could choose the Go-faster salad, which is a large bowl of mixed raw vegetables in a light salad dressing, giving you energy without making you gain weight. And what kind of dishes do you think would be on the menu at the “Clever Café”?
So what’s going to happen to hamburgers and biscuits? Will the concept of eating food, because it’s tasty, go out of fashion? Of course not! Junk food is also changing. If ice-cream is not good for children, can’t we give them fat-free, sugar-free tofu ice-cream? Unhealthy food is going out of fashion, so brands are changing. We are told not to drink cola because of the sugar and caffeine content so cola companies are making sugar-free and caffeine-free drinks. We are told dried fruit is a healthier snack than biscuits so some biscuit companies are making biscuits with added vitamins.
