问题描述：
With his student __,the teacher felt unhappy.A.disappointed B.to be disappointed C.disappointing
D.being disappointed.
答
前半句 with his student disapointing是独立主格结构,前一句做主句的伴随状语,动词用现在分词时表示原因.动词为不定式时表示目的或结果.
本句的意思是：学生令人失望,所以老师不高兴.表示原因所以用现在分词选A
disapointing令人失望的.
disappointed是形容词,意思是失望的.
祝楼主开心进步,希望对你有所帮助.!那不是应该选C吗不好意思。是选C 我打错了。
