hearrivedattheparty.他到達聚會的時候，大部分的客人已經(jīng)走了。Helenhadleftherkeysintheofficesoshehadtowaituntilherhusbandcamehome.海倫把鑰匙忘到辦公室里了，因此她不得不等她丈夫回來。4a.Makesentencesusingbythetimeorbefore.1.Timwentintothebathroom.Marygotup.BythetimeMarygotup,Timhadalreadygoneintothebathroom.2.Thecoffeebecamecold.Iputcreaminthecoffee.__________________________________________________3.Theteachercollectedthemathhomework.
