Question

Answer 1

When I entered the living room,mother didn't say anything ,but I noticed a ___ look had come over her face.
原题是这个吧,你都没给全
surprised 是过去分词,表示事物本身感受的惊讶.
surprising是动名词,表示事物给人的感觉.
例句中,是mother自己感到惊讶,只不过被你发现了.你并没有惊讶..所以用surprised..
以上是在百度是查到的,补充一点,这里是表达母亲没想到你会在这个时候回来,因此她脸上才会有惊讶的表情
One is surprised by something.
Mother was surprised by my entering the living room.
母亲对我进来这件事感到惊讶.
因此你可以说
My entering the living room was surprising to my mother.
我进来这件事使母亲感到惊讶.
看到同一个意思的不同用法了吧
