二、阅读理解
①Over thepast fortyyears,cars havebecome lesspolluting.Many peoplenow driveelectric cars（）（放）e-cars.And thereare feweremissions4E fromcars.However,cities suchas Londonand LosAngelesare stillfighting airpollution.Using cleaner cars isa goodstep,but isthis enough
②A surveyshows thatmore than40percent of the carsonly haveone personinside.But acar trip（电）.takes alot ofelectricity Inthe U.S.,more than60percent ofelectricity stillcomes fromfossil fuels（化石燃料）.So ifall ofus wereto usee-cars,the emissionswould onlybe cutdown by25percent.（）3And thereare otherthings tobe worriedabout.Roads andother systemsfor carsneed alot of（土土也）space.About24percent ofLondons landhas beenused tobuild thesesystems.In manyU.S.cities,this numbercan beas highas40percent.The WorldHealth Organizationadvises citiesto createatleast9m2of greenspace foreach person.However,in manyfast-growing citiesaround the world,eachgets lessthan2m2because theyhavetouse moreland forroads andparking.
