Having a trip abroad is certainly good for the old couple, but it remains_____B_ whether they will enjoy it.
A. to e B. to be en C. eing D. en
有remain doing这种用法!—-后面接V-ing作表语。
例如:
She remained standing though we repeatedly asked her to sit down.虽然我们三番五次地请她坐下,她还是站着。
咱们这个问题关键就是被动,在这里it形式主语,真正的主语是前半句:Having a trip abroad is certainly good for the old couple!
句子大意:
海外旅游对于老年夫妻当然好,但是不管他们是否享受这个过程这种情况还能被看到!
如果这个非谓语做 主语 的话,那肯定咯例如:it is bad for people’s health to eat too much salt.这个句子里,it是形式主语,to eat too much salt是非谓语(而事实上,它才是真正的主语)这个句子本来应该说to eat too much salt is bad for people’s health .这个时对数函数公式大全候 to eat too much salt 就做主语了.其实呢,非谓语动词,就是动词堕落的表现,记住这个就好.堕落的形式就三种:1.to do ;2.doing 3.done.其实不难记住的。
