ishisdream.TolearnEnglish

isimportantanduseful.一般位于句首，谓语动词用单数形式。为了避免句子“头重脚轻”，往往用it代替不定式作形式主语，而将不定式放在后面作真正的主语。=Itishisdreamtotravelaroundtheworld.=ItimportantandusefultolearnEnglish.GrammarFocus用法Wedecidetoplant

treesthisweekend.Iwanttobeavolunteer.2.作宾语LilywantstofindajobasanEnglishteacherinBeijing.GrammarFocusOurteacheraskedustocleantheclassroomafterschool.
