You may have heard adults say they are uncomfortable in the morning without a cup of coffee. One reason they may feel that way is that coffee contains caffeine(咖啡因). Caffeine occurs naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water.

The US government is especially worried about the problem. That’s why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What’s more, caffeine is habit-forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired.

One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount.

The Institute of Medicine is also working on caffeine-safety measures. “Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine’s effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied,” said Stallings, a member of the institute.

Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that.

Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep.

The interview had been going on for about 20 minutes and everything seems to be going well.Then,suddenly,the interviewer asks an unexpected question,“Which is more important,law or Dove?”

The question in the first paragraph comes from a test called the Keirsey Personality Sorter.It is an attempt to discover how people solve problems,rather than what they know.This is often called an aptitude test (能力倾向测验).

According to Mark Baldwin many job applicants in China are finding this type of questions difficult.When a Chinese person fills out an aptitude test he or she will think there is a right answer and they may fail because they try to guess what the examiner wants to see.
