The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. [22]But be careful what you pour down your throat. Something that looks cool may not be good for your health.
There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition lists also contain various things from vitamins to ginseng. Sounds great!
But after a careful check you may find that most energy drinks contain high levels of caffeine. [24]These drinks are typically 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 raises your heartbeat. Because of this, the International Olympic Committee has limited its use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or tea.
Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 per cent of boys aged 8-12 take in more caffeine than their parents.
There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.
Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.
22 What is the passage mainly about?
23 What nutrition do energy drinks usually claim to contain?
24 Who are among the target consumers of most energy drinks?
25 What is the speaker’s attitude towards taking energy drinks?
选项
A、The changing of weather.
B、The health of teenagers.
C、Energy drinks and their nutrition.
D、The danger of energy drinks.
答案
D
解析
短文先用天气热、做运动口渴引出冷饮的话题,然后用But,话锋一转,说可要当心灌人喉咙的东西!有些东西看起来很爽,可能对你的健康并没有好处。可见短文谈drinks及其好处(或不好处)。文章后面还明确指出,“能量饮料存在潜在的健康风险”,danger是risk的同义表达。D正确。
