18．When people talk about air pollution，they usually think of smog，acid rain（酸性 雨），and other forms of outdoor air pollution．But did you know that air pollution also exists inside homes，offices，hotels and other buildings？The air in your home can be 2to 100times more polluted than the air outdoors！In fact，some American doctors say that 50% of illnesses have something to do with polluted indoor air．
Air pollution influences our health in many ways．Young children and the old often suffer more from air pollution．People with health problems may also suffer more when the air is polluted．Indoor air pollution can harm people's eyes，nose and throat．Air pollution，both indoor and outdoor，can also lead to lung cancer，heart disease，and even harm to the brain!In the great London fog in 1952'4，000people died in a few days because of air pollution!It is said that half a million young kids and women die each year in India because of indoor air pollution!
The re're many ways to reduce indoor air pollution．Here are some of them and see if they can help you：
★Increase the amount of outdoor air coming indoors and open your windows for 15to 30minutes each day．
★Turn off all the lights and fans when you don't need them．
★Share your room with others when the air conditioner is running．
★Don't smoke and try to stop your family members and relatives from smoking．People who smoke are going to have trouble breathing and even die someday．If you're smart，don't ever start．
★Environment-friendly products，such as water-based paints pollute less and work just as well．

分析 空氣污染尤其是室內(nèi)的空氣污染在許多方面影響我們的健康，室內(nèi)空氣污染會損害人的眼睛、鼻子和喉嚨，還可以導(dǎo)致肺癌，心臟疾病，甚至危害大腦！減少室內(nèi)空氣污染的方法很多包括：★增加室外空氣進(jìn)入室內(nèi)的量．★及時關(guān)燈和風(fēng)扇．★與他人分享你的房間的空調(diào)．★不抽煙并且阻止你的家人和親戚吸煙．★用不污染環(huán)境的產(chǎn)品，如水性涂料等．

解答 61．B 細(xì)節(jié)理解題．根據(jù)The air in your home can be 2to 100times more polluted than the air outdoors可知室內(nèi)空氣污染更嚴(yán)重．故選B．
62．D 細(xì)節(jié)理解題．根據(jù)Indoor air pollution can harm people's eyes，nose and throat可知室內(nèi)空氣污染會損害人的眼睛、鼻子和喉嚨．故選D．
63．B 細(xì)節(jié)理解題．根據(jù)文章內(nèi)容可知帶星號的就是作者提到的五個減少室內(nèi)空氣污染的方法．故選B．
64．D 細(xì)節(jié)理解題．根據(jù)Environment-friendly products，such as water-based paints pollute less and work just as well可知水性涂料是不污染環(huán)境的．故選D．
65．C 細(xì)節(jié)理解題．根據(jù)Share your room with others when the air conditioner is running．可知我們應(yīng)該與他人分享房間的空調(diào)．故選C．

點(diǎn)評 做題時要在理解好文意的基礎(chǔ)上，與題目有機(jī)的結(jié)合，從文章中找到相關(guān)細(xì)節(jié)性的句子與選項(xiàng)細(xì)細(xì)比對，進(jìn)行選擇或推理判斷，選出符合文章內(nèi)容的正確選項(xiàng)．做題注意靈活，有時可采用排除法或直選法確定出最終答案．

13．If you take away many sentences from somebody's written work as your own without permission，it's called plagiarism（剽竊），but if you take the knowledge from a piece of work by another and change the words，then it's not plagiarism．This is the difference between using the Internet and plagiarism．If you are given homework to work out math problems，then you should use your brain（大腦）without a computer!If the teacher asks you to learn something about a famous literary person，you can use the computer，If you take down the main important  information of the task，it's OK．However，if you run to the computer to do your thinking for you all the time，you don't exercise your brain and you will forget how to work out a problem．By using a computer，students may get a useful answer fast，to finish homework，but when they have to face an exam，they will not be ready for it．
  Though teachers say finding or buying homework answers online is not many in schools，an  interview with school students shows only 10% hopes to finish their holiday homework by themselves．They complain that the homework is too much for them to finish．Besides，many of students have to go to all kinds of training classes during the holiday．These take away much of their time for doing homework．So they want to find or even buy answers online or copy each other's homework．Students should learn that being a student is about getting skills，but not just getting quick，cheap"answers"for homework problems．I mean we should use the computer properly．
