tom,_____(not walk)on the grass the geese____(catch) the fish now

问题描述:

tom,_____(not walk)on the grass the geese____(catch) the fish now

do not walk 意思是:Tom,不要走在草地上.(Tom,不要践踏草坪),否定祈使句,don't +动词原形
is catching 那只鹅正在捉鱼.正在进行的动作用一般进行时,be动词+动词-ing为什么不用doesn't 呢??因为这种祈使句的主语其实是you,但是一般情况下都会省略,原本的句子是:you don't walk on the grass.you被省略了 就变成don't walk on the grass ^ ^
