一.

take表示“乘、坐”某一交通工具。如：Myfatherusuallytakesabustowork.我爸爸常乘公共汽车去上班。注意：take和by都有“乘、坐”之意。take是动词，后面接具体的交通工具，且在表示该交通工具的名词前一般应有冠词等修饰语；而by是一个介词，它后面所跟的表示交通工具的名词前一般不可用冠词等修饰语。by短语在句中修饰动词等作状语。如：

格林先生经常乘火车去上班。MrGreenoftengoestoworkbytrain.=MrGreenoftentakesatraintowork.1.Itakethebus

togettoschool.(同义句)2.Shetakesthecartogettowork.(同上)3.Theywalktoschool.(同上)4.Ittakeshim

(对划线部分提问）Igettoschoolonthebus/bybus.Shegetstoworkinthecar/bycar.Theygettoschoolonfoot.Howlongdoesittakehimtowalkthere?二.take表示“花费时间”之意，其常用句型为“Ittakessb.sometimetodosth.”，意为“某人花多少时间做某事”，注意后面动词前的to不可丢掉。如：Ittakeshertwentyminutestowalktoschooleveryday.她每天步行去上学要花二十分钟的时间。Ittakesmehalfanhourtodomyhomeworkintheevening.晚上我要花半小时做作业。三.含tak
