11、is/are.?拓展：1.weigh用作及物动词，意为“称的重量”。如:Heweighedthefish.他称了这条鱼。2.weight名词，意为“体重；重量”。eg:loseweight减肥,知识讲解：,Yourbagmustnt_toomuchifyouwanttotakeaplane.Youdbetteraskthetravelcompanyaboutthetotal_forallyourbags.(2017天津宝坻八中月考)A.weigh;weightB.weight;weighC.weighed;weightD.weight;weighed,练习：,A,2.Thiselephantw
