2.阅读短文,根据短文内容,从下面各小题所给的四个选项中,选出最佳选项.
One billion teenagers and young adults around the world are in the face of losing their hearing by listening to loud music.This is according to the World Health Organization.
Few things can make people happy and full of energy like good music.Many people believe louder is better if you are listening to rock and roll.But if you really listen to the music loudly,even really good music,it can hurt your hearing badly.
If a person takes a subway to go from one place to the other for half an hour in the morning and a half an hour in the evening,and every day has to turn up the volume on his audio device because there is so much of noise of the train and everything around,and is listening to for one hour every day,his hearing is going to be hurt seriously in a few years,in a couple of years time,for sure.
There can be many kinds of unsafe levels of sound.It depends on how lond the sound is and how long you listen to it.Unsafe can mean noise levels of 85 decibels  for eight hours a day or 100decibels for just 15minutes.
There are simple ways to protect people from unsafe sound levels.Young people who wear earplugs during concerts can enjoy music at 90decibels as much as they can at 110decibels.But earplugs may not look very cool.The fact that earplugs may look un-cool may be true today,but if there is nothing wrong with your hearing in the future may be true and wearing earplugs may actually be cool.
Another common suggestion is to turn down the volume on your personal audio devices.The World Health Organization also advises young people to limit their use of such devices to less than one hour a day.
Besides,the World Health Organization reminds people to use technology,such as smart audio devices keep listening levels safe.

分析 短文大意:根据世界卫生组织的报道,全世界有十亿青少年正通过听响亮的音乐而失去听力.很少有东西能像好的音乐一样使人开心并充满活力,很多人认为听摇滚乐时声音越大越好,但是如果你听响亮的音乐,即使是好的音乐,也会伤害你的听力.如果一个人在上、下班途中听着音乐,早上坐地铁半小时,下午半小时,因为车上及周围的噪声太多,不得不把设备音量开大,几年后,肯定两年后,他的听力就会受到严重的伤害.不安全的声音水平有许多种,这要看你听多久了及你的声音有多响,85分贝一天八小时或100分贝一天15分钟就意味着不安全.远离不安全的声音有一些简单的方式:听音乐会时带上耳机;关小你个人声音设备上的音量;利用科技,比如智能设备来保持声音处于安全的水平.

解答 66.D 细节理解题.由第二段的第一句话:Few things can make people happy and full of energy like good music.很少东西能使人像听好的音乐那样开心并充满活力.可知是听好的音乐使人开心并充满活力.故选D. 
67.A 词义猜测题.句意:every day has to turn up the volume on his audio device because there is so much of noise of the train and everything around因为有那么多的车和周围事物的噪声,每天不得不把语音设备turn up the volume.可以推测出在听音乐时,因为噪声大,所以不得不把音量调高.故选A.
68.B.细节题.结合第四段It depends on how lond the sound is and how long you listen to it可知取决于音乐有多响亮,你听了多久,故选B.
69.A.推理判断题.根据短文第四段的:Unsafe can mean noise levels of 85 decibels for eight hours a day or 100 decibels for just 15 minutes.可知不安全的声音水平是85分贝每天八小时或100分贝每天15分钟,低于这个分贝数,少于这个时长,就是安全的.故选A. 
70.B 细节理解题.根据短文最后三段话,文中介绍了三种使人们远离不安全的声音水平的方法:听音乐会时带上耳机;关小你个人声音设备上的音量;利用科技,比如智能设备来保持声音处于安全的水平.故选B.

点评 细读题材,各个击破.掌握全文的大意之后,细细阅读每篇材料后的问题,弄清每题要求后,带着问题,再回到原文中去寻找、捕获有关信息.

17.When you hear about trees cut for paper,you might think of your favorite trees in the backyard,nearby parks or wild forests being cut to pieces.
the good news is that production and use of paper will not cause forests to disappear.Most trees used for paper come from timberlands(林地).People plant trees here for use.It usually takes 10to 20years for trees to grow big enough to be cut down.During that time,trees provide a home for animals and produce oxygen(氧气) for the earth.And after people cut down the big trees,they plant small ones again.
Often,a tree is not cut down for making paper at all.People use the big part for buildings.Paper is then made from the left small part.
We also recycle paper-People collect used paper and turn it into new products,likes boxes,newsprint and writing paper,in the factory.So it's important for us to recycle paper and reduce(减少) the amount(数量) of it in landfills(垃圾处理场).
