12.【Unit3Period4】及答案解析
Ⅰ.阅读理解
A
Now,we know that if we do not get enough vitamins,we are at risk of developing a number of diseases.As a result,vitamin supplements(补品),though expensive,are popular with people who worry that they are not getting enough vitamins from the foods they eat.But contrary to what many people think,medical experts have found little evidence that most supplements do anything to improve health or protect against disease.
In fact,medical experts warn that taking too many of some vitamins can be harmful.For example,too much vitamin E can cause bleeding.People should discuss what vitamins they take with their doctors,as some vitamins can produce harmful side effects when mixed with medicines.
Experts,however,do say that sometimes vitamins can help prevent disease.People who know they lack a particular vitamin should take vitamin supplements.Some older adults,for example,may not have enough vitamin
B-twelve.This is because,as people get older,their body loses its ability to take it from foods.Also,people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.
Different vitamins are found in different foods.Vitamin A is found in fish liver oil.It is also in the yellow part
of eggs.Sweet potatoes,carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.Vitamin B-twelve is found in green leafy vegetables and other foods,like fruits.Vitamin K can be found in pork products.
In fact,for most people,a balanced diet can ensure enough of the vitamins our bodies need.So,it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.

People should listen to music for no more than one hour a day to protect their hearing,the World Health Organization suggests.
It says1.1billion teenagers and young adults are at risk of permanently damaging
their hearing by listening to“too much,too loudly”.WHO figures show43million people
aged12~35have hearing loss and this number is increasing.In that age group,half of
people in rich and middle-income countries were exposed to unsafe sound levels from
personal audio devices.Meanwhile40%were exposed to damaging levels of sound from clubs and bars.The percentage of US teenagers with hearing loss went from3.5%in1994to5.3%in2006.
Dr Etienne Krug,the WHO’s director for injury prevention,told the BBC,“What we’re trying to do is raise awareness of an issue that is not talked about enough,but has the potential to do a lot of damage that can be easily prevented.”The full report argued,“While it is of vital importance to keep the volume down,limiting the use of personal audio devices to less than one hour a day would do much for reducing noise exposure.”
The World Health Organization recommends keeping the volume to60%of the maximum as a proper way for listening.For people on plane or train,it says noise-cancelling(降噪)headphones allow music to be heard clearly at a lower volume.And the WHO adds that earplugs(耳塞)should be worn at noisy places and advises taking“listening breaks”now and then.
“We do realise that many risk factors linked to pleasure are not easy to change,but we have to make people aware,”Dr Krug said.
But as well as calling for personal responsibility,the WHO says governments and companies have a responsibility.It says clubs should provide relaxing rooms and give out free earplugs,headphone companies should set limits on the volume,and governments need to adopt stricter laws.
Paul Breckell,the chief executive of the charity Action on Hearing Loss,said,“When listening to loud music, for every three decibels(分贝)increase in level,to stay safe you should cut half of your listening time.”
【语篇概述】世界卫生组织(WHO)研究发现,每天听音乐的时间超过1个小时有损人类听力。

保护听力健康,已经是一个不容回避的世界性话题。

A.1.1billion teenagers and young adults have hearing loss.
B.43million people aged12~35are at risk of permanently hearing damage.

D.40%of the hearing loss were related to the noise from clubs and bars.
【解析】选D。

细节理解题。

根据第二段可知,A项数值应为43million;而B项数值应为1.1billion;C项应该是half of people in rich and middle-income countries;从“Meanwhile40%were exposed to damaging levels of sound from clubs and bars.”中可以看出,D项正确。

5.The best way to reduce noise exposure is to__________.

A.WHO finds listening to music for more than one hour a day damages your hearing.
B.WHO’s suggestions on the best way of listening to music in people’s life.
C.Keeping the volume to60%of the maximum is a proper way for listening.
