题目内容

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 appears 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.

It has been a long time since I did anything good for the environment. Feeling responsible to protect the environment, I decided to take the action again. I told my idea to my friends and we planned to plant tree on the hill in the countryside. We came to the foot of the hill and selected a place where looked suitably and settled down. We spend a few hours digging holes and placing the young seedlings. Then we wrote our wishes on cards one to one and buried it deep down the roots of the trees. We also took a lot of pictures. We were such busy that we didn’t realize that it was time to go back. I felt really glad that we made difference to the environment.

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized(把……归类) as “honor” help you create this life of good feelings.

Here’s an example to show how honorable actions create happiness.

Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk’s mistake, we would drive home with a sense of sneaky (暗中的) excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.

Then, what is it to do with our sense of happiness?

In the first case, where we don’t tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk’s attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable actions we gain the deep internal rewards of goodness and a sense of nobility.

There is a beautiful positive cycle that is created by living a life of honorable actions.

Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it’s easy to think and act honorably again when we’re happy. While the positive cycle can be difficult to start, once it’s started, it’s easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

1.According to the passage, the positive action in the example contributes to our __________.

A. friendly relationship B. financial rewards

C. advertising ability D. self-respect 21*com

2.The author thinks that keeping silent about the uncharged item is equal to __________.

A. lying B. cheating

C. stealing D. advertising

3.How will we feel if we let the clerk know the mistake?

A. We’ll be very excited.

B. We’ll have a sense of honor.

C. We’ll feel unfortunate.

D. We’ll feel sorry for the clerk.

4.Which of the following can be the best title of this passage?

A. Happiness through Honorable Actions

B. Importance of Peacefulness

C. Ways of Gaining Self-respect

D. How to Live Truthfully
