根据短文内容,判断正误。
正确用“T”表示,错误用“F”表示。
()1.CO2isagreenhousegasthatcanmaketheearthwarm.
()2.WatchingTVandtravelinginataxicanproducelittleCO2.
()3.Ifweuseadryerfivetimesperweek,weproduce154kgofCO2peryear.
()4.Ifwespendlesstimetakingashower,wecancutthenumberofCO2.
()5.Thelessofa"
weleave,thebetterourenvironmentwillbecome.
解析
1.T根据第一段第三句和第四句话可知CO2是一种能使地球变暖的温室气体。
2.F根据“TVsetsandDVDplayersproduce723kgofCO2ayear.”和文章标题,可知看电视和开车能产生很多CO2,不是几乎不产生。
所以此句的表述是错误的。
3.F根据“Ifyouuseyourdryerfivetimesperweek,youproduce185kgofCO2peryear.”可以判断此句是错误的。
4.T根据每天洗澡8分钟和每天洗澡6分钟产生的二氧化氮的对比说明,时间越短,产生的二氧化碳就相对越少,所以此句的表述是正确的。
5.T根据“Toprotectourenvironment,weneedtoleavelessofa'
carbonfootprint'
"
,可知此句正确。
