某事花費某人…時間e.g.Ittakesme30minutestofinishmyhomework.sb.sometimetodosth.take用法小結(jié)

一.

take表示“乘、坐”某一交通工具。如：Myfatherusuallytakesabustowork.我爸爸常乘公共汽車去上班。注意：take和by都有“乘、坐”之意。take是動詞，后面接具體的交通工具，且在表示該交通工具的名詞前一般應(yīng)有冠詞等修飾語；而by是一個介詞，它后面所跟的表示交通工具的名詞前一般不可用冠詞等修飾語。by短語在句中修飾動詞等作狀語。如：

格林先生經(jīng)常乘火車去上班。MrGreenoftengoestoworkbytrain.=MrGreenoftentakesatraintowork.1.Itakethebus

togettoschool.(同義句)2.Shetakesthecartogettowork.(同上)3.Theywalktoschool.(同上)4.Ittakeshim

(對劃線部分提問）Igettoschoolonthebus/bybus.Shegetstoworkinthecar/bycar.Theygettoschoolonfoot.Howlongdoesittakehimtowalkthere?二.take表示“花費時間”之意，其常用句型為“Ittakessb.sometimetodosth.”，意為“某人花多少時間做某事”，注意后面動詞前的to不可丟掉。如：Ittakeshertwentyminutestowalktoschooleveryday.她每天步行去上學(xué)要花二十分鐘的時間。Ittakesmehalfanhourtodomyhomeworkintheevening.晚上我要花半小時做作業(yè)。三.含tak
