非谓语句子
Having a trip abroad is certainly good for the old couple, but it remains_____B_ whether they will enjoy it.
A. to see B. to be seen C. seeing D. seen
请问没有remain doing 吗?这里为什么不能用remain seeing ?

Having a trip abroad is certainly good for the old couple, but it remains_____B_ whether they will enjoy it.
A. to see B. to be seen C. seeing D. seen
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！
