9．Many Americans have been leaving their cars at home and riding to work on bicycles．Andy Clark is the leader of the League of American Bicyclists．His group supports bicycling for fun，fitness and transportation．
Clark says this is good news for the environment．He says riding a bicycle to work does not burn fossil fuel （能源） or creates dangerous pollutions．Experts say the effects are the most important on short trips．The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work．Shorter car trips set out more pollution into the air for each kilometer drive．This is because the car engine will set out the harmful air when it warms up before it can work well．
James，a member of Congress （國會(huì)），is a strong supporter of bicycle use．He says cities，counties，state governments and state highway transportation agencies are planning the roadways of the future．They are creating roads and paths for bicycles in cities and between communities．
Last year，Portland，the Pacific Northwest city in the state of Oregon，had the highest percentage of bicycle users in the United States．Portland has been doing progressive city planning for many years to create special paths for bike riders．

Also think about the money you will save by not smoking．You can spend it on much more fun things like music，clothes or nice food．
To stay away from smoking，or to help stop，keep a list with you saying why smoking is bad．

14．Cellphones help us easily find people anywhere at any time．However，using cellphones too often may cause cancer．It's reported that people who used a cellphone for 10years or more were more likely to get brain cancer．
The suggestions below may help you reduce the risk （風(fēng)險(xiǎn)） of cancer：
◆When using your cellphone，try to keep it away from your body as much as possible．Don't put it under your pillow （枕頭）or on a bedside table when you go to sleep．
◆When you're on the cellphone，use the speaker．In this way，you have just 1/100th of the contact（接觸） with radiation you have when you hold it to your ear．An earphone is also a good idea．
◆Try to keep your conversations short．If you need to talk longer，use an ordinary phone instead．
◆Change ears when you're using your cellphone．Before putting it to your ear，wait until the  person you are calling picks up the phone．
◆Your phone gives out radiation when you talk or text （發(fā)短信），but not when you're listening  or getting messages．Listening more and talking less can lower the risk of cancer．
◆Do not use your cellphone when the signal （信號(hào)）is weak or when moving at a high speed，for example in a car or train．At high speeds your phone is trying to pick up signals，and this  increases the radiation it gives out．

任務(wù)型閱讀：根據(jù)短文內(nèi)容，填寫下列表格．
Healthy tips on cellphone use
☆Try to （81）keep your cellphone away from your body，both when using it and sleeping．
☆Using the speaker or an （82）earphone is a good way to reduce the radiation．
☆A(yù)void using a cellphone to make （83）long conversations．
☆Don't press the cellphone to your ear until the person you are calling （84）picks up the phone．
☆Listening more and talking（85）less can lower the risk of cancer．
☆Don't use your cellphone when the signal is （86）weak or when moving at a high speed．

Think of your favorite scary movie and its sounds-footsteps，loud rain，and creaking doors．Many sounds can't be recorded during the filming of a movie，so Foley artists produce them in their studios（工作室）．They create the sounds of a fight scene，and the wind，rain，and thunder in the background．In a Foley artist's studio，there are even special （80）Bfor recording different kinds of footsteps．
