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. 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.

These days the subject of security(安全) on campus is talked about quite often.  Some students' mobile phones are stolen, some students fight with and hurt one another, and others are knocked down by the fast running bikes or cars.
These problems arc common on campus. I think there are three causes for these. Firstly, some students do not take good care of their properties. They are still young and not careful enough. Secondly, some students want to do everything well. They want to be the winners in exams, and they also want to be the winners in fightings.  And thirdly, the campus guards(保安)do not carry on their duties well. They don' t regulate the traffic in the busy hour.
In order to have a secure campus, all the students should be very careful about their properties. They should also mind their behaviors(举止) and act politely.
