【题目】Teenagers are often a difficult group. With all those hormones（荷尔蒙） flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food are likely to be happier than other teens.

The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are.

Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food.

Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining(克制) from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too.

【题目】Everyone gave a _________(欢呼）when Gil more crawled out of the ruin, unhurt.

【题目】If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.

There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.

Keep up shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.

If you don’t think that you will get help before night comes, try to make a little house---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.

What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.

【题目】We know that cigarette smoking kills． So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco． Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them． They are powered by battery （电池）．

However, if e-cigarettes are so safe, why has the United States Center for Disease Control（CDC） seen an increase in telephone calls about e-cigarette poisonings?

The answer is children． Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns． More than half of these calls were for children aged five and younger． The devices had made them sick．

Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation． Meaning, the U．S． federal government does not control e-cigarettes even though they contain liquid nicotine． Mr．McAfee adds that liquid nicotine is a well-known danger． Mr．McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed． It can cause stomach pain or a sense of unbalance． And too much nicotine can kill,

Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do．He notes that almost 500,000 Americans die each year from cigarettes． "So, cigarettes are the winner in that contest．" E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes． So, the U．S．Surgeon General Boris D． Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use．

But McAfee worries that teenagers may think electronic cigarettes are harmless． They could become addicted to the nicotine and then start smoking real cigarettes． In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing．

【1】What do the producers think of e-cigarettes?

A． Dangerous． B． Expensive．

C． Safer． D． Cheaper．

【2】Why did the CDC receive so many calls about e-cigarettes?

A． Parents feared that their children might get poisoned.

B． Parents found the device useless in quitting smoking．

C． Children swallowed the liquid nicotine from the device．

D． Children might get addicted to playing with the device．
