1 . People should listen to music for no more than one hour a day to protect their hearing, the World Health Organization (WHO) suggests.
It says 1.1 billion teenagers and young adults are at risk of permanently damaging their hearing by listening to “too much, too loudly”.
It said audio devices(音频设备), concerts and bars were causing a “serious threat”.
WHO figures show 43 million people aged 12-35 have hearing loss and the number is increasing. In that age group, the WHO said, half of the people in rich and middle-income countries were exposed to unsafe sound levels from personal audio devices. Meanwhile 40% were exposed to damaging levels of sound from clubs and bars.
The proportion of US teenagers with hearing loss went from 3.5% in 1994 to 5.3% in 2006.
“What we’re trying to do is raise awareness of the problem that is not talked about enough, but has the potential to do a lot of damage that can be easily prevented,” said Dr Etienne Krug, the WHO’s director for injury prevention.
The full report argued: “While it is important to keep the volume down, limiting the use of personal audio devices to less than one hour a day would do much to reduce noise exposure.”
Dr Krug said: “That’s a rough recommendation, it is not by the minute, to give an idea to those spending 10 hours a day listening to an mp3-player. But even an hour can be too much if the volume（音量）is too loud.”
1. What might be the main cause of hearing loss according to the passage?
2. How many people aged 12-35 were most likely to suffer from hearing loss according to WHO?
3. Which of the following ideas would Dr Etienne Krug agree with?
4. What might be the best title for the passage?

2 . A US student has just spent 30 days on an “insect diet ” – eating insects three times a day. Camren Brantley-Rios says traditional meats such as pork and beef are unable to continue and he wanted to try out what many consider the diet of the future.
Many people would not like the idea of eating insects distasteful, even if it were not disgusting. Not so long ago Brantley-Rios was among them. But for the last month he has been eating insects for breakfast, lunch and dinner.
“I’m mainly sticking to three kinds,” he says.
Occasionally he has included different insects. Preparing these he “actually cried”, though he insists they were surprisingly good.
Insects consume fewer resources than animals, like pigs and cows, to produce the same amount of protein(蛋白质), Brantley-Rios says – and more than two billion people worldwide include insects in their regular diet, according to the UN Food and Agriculture Organization.
“There’s not really a need to eat insects in America because we have it so nice,” Brantley-Rios says. “We have finer meats and we’re lucky to have that luxury(奢侈), so there’s not much of a pressure to eat insects right now. But what a lot of people are trying to do is make it a little bit more marketable.”
He has ordered insects from farms that usually supply zoos, which need them “to feed certain animals”. He has always made sure the insects have been fed on an organic diet, he says, and only bought species he knows are safe to eat.
He knows that one person eating insects won’t make much difference. To have a real environmental effect, millions would have to follow his example.
1. Why has the US student tried out an “insect diet”?
2. What can we learn about Brantley-Rios from Paragraph 2?
3. What does the underlined part “actually cried” in Paragraph 5 mean?
4. How does Brantley-Rios guarantee the safety of his insect diet?
