The weather is getting hotter and 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" advertisement on TV. Most of them have beautiful colors and cool names. They tell you they are helpful to your health. Sounds great and lots of people believe them!

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 he careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited (限制) its use. Caffeine in most energy drinks is as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

SAVE THE OCEAN

STUDY TOUR

 Every year, more than 1.1 million tons of plastics end up in the ocean. It can take centuries for the waste, such as plastic bottles and single- use bags, to break down. That seriously harms(伤害) wildlife living there. Are you an eco- warrior(生态卫士)? Are you ready to help save the ocean from plastic pollution?

Thousands of miles from the Earth, in outer space, is a small planet, Fliptune. It is dark and cold, far from the Sun, behind a much bigger planet. Little green aliens (外星人) live there. They use torches (手电筒) to see. 

One day, a young alien, Neila, put the wrong batteries (电池) in her torch. 

Suddenly (突然), there was bright light. It went up into the sky, around the Sun and reached the Earth. 

The light hit a boy called Billy and his dog. Neila quickly turned the torch off, but the pair were caught by the light. They flew through space and landed near Neila. 

"Hello, " said Billy. Neila smiled. 

"Wow!" said Billy, "Everything's made of ice cream!"

"The ice cream never melts, and nobody eats it. It's too cold here, " said Neila. 

Neila looked sad. "Can you help us?" she said, "We need sunshine to make things grow. "

"No problem, " said Billy, "Can you get us home? I have an idea. "

"Wait there!" said Neila. She got her torch, put the wrong batteries in again——ZOOM! Billy and his dog flew back to the Earth. 

Billy pointed his bedroom mirror (镜子) between the Sun and Fliptune. The sunlight bounced off(弹出) the mirror and up onto Neila's planet. 

Thanks to Billy, Fliptune is not cold any more. Billy moves the mirror every day to keep the sun shining there. Now Neila and her friends sit in the sun and enjoy all the free ice cream.
