The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.
There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!  
But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine makes your heart（心脏）beat fast. Because of this, the International Olympic Committee has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks.

Passage 1  Mobile Phone Madness
How much do you love your mobile phone? A Chinese student had to call 110 for help this week after he got his arm stuck in a toilet trying to rescue(援救) his mobile phone. After dropping his phone in the toilet, he decided to wrap(包，裹) his arm in newspaper in the hopes of keeping clean. But the newspapers became larger in size in the water, and then even his roommates couldn’t help him pull his arm out. So policemen were called and they spent an hour unsticking the stuck student.
Passage 2  Crazy Pet Lovers

But would they spend 7,000 English pounds (68,000 yuan) on a wedding(婚礼) for their pets? And that’s what a couple in Brazil spent on a fancy wedding for their pet Yorkshire terriers( a kind of dog).
Passage 3  Oh, rats!
When something goes wrong, you can often hear Westerners cry “Oh, rats”. But when it comes to Southern China, “Oh, rats!” can mean it’s what you want for dinner. According to a report in China Daily, some restaurants in Guangzhou serve rat meat. But, actually, most of those rats are field mice. What would Mickey Mouse say?
Passage 4  Liar(说谎者), liar
Here’s some news that most women already know. Men tell more lies than women. The London Daily Mail cites(引用) a new study that says men tell about three lies a day, while women tell only two lies a day. Men are also less likely to feel guilty about lying, according to this week’s survey of 3,000 people by a research organization called One Poll. According to the Poll, lying to our mothers is very popular. But then, so is lying at work. And both men and women will lie when it comes to how much they’ve drunk. So how easy is it to tell when someone is lying?
