有关非谓语动词.
.___again later if the webpage you are looking for is temporarily unavailable.A.Try B.To try C.Having tried D.Trying 后面有个is,句子已经有动词,那前面那个空为什么不用非谓语呢
答
这题是选A吗
答
祈使句…开头用动词原形
答
if the webpage(从句主语) you are looking for(定语从句,修饰webpage) is (系动词)temporarily unavailable(表语).这是if引导的条件从句
前半部分是句子的主干,因为没有主语,只能是祈使句,所以这里只能选A.
