该用什么时态? They _____(put)the young trees into the holes and ____(fill)the holes with earth after they dug the holes . "Let's try to _____( save ) the young tree.Let's ____(move) it into our garden."
第一个:看后面那个"dug"知其是过去时态(原形dig),那么就用过去式,其答案:put,filled 第二个:try to do sth是一个固定搭配,是"试图做某事"的意思.另外,"to"后面动词一般用原形.第二个空,是个祈使句动词用原形.其答案:save,move 类似这样的说法经常听到如"Let's go "学英语有时要么那么点联想,是吧,希望对你有帮助!...
