Ⅲ.阅读理解(共5小题;每小题2分,满分10分)
Sometimes boys do risky things for many reasons, but most of the time they just try to prove to their friends that they are brave enough. I experienced this when I was spending my summer holiday with my parents on the beach.
On a warm but cloudy afternoon, I was walking on the beach when I met a boy called Bob. We walked along the beach and talked a lot. Then he said that it was fun playing on the cliffs(悬崖). I told him that I was not allowed to go near that place (Mum and Dad had always told me it was dangerous to play there). He called me a coward(胆小鬼). I wanted to prove to him that I was just as brave as he was, so I agreed to go with him.
We decided to make our way down to explore the area, so Bob started to climb down and I followed him. Unluckily, some rocks came down after us. One of them nearly hit my head. We could not get back up. We shouted and shouted for help, but for a long time, no help came. I was really scared. I wanted to cry. Then, we heard some sounds. Someone had heard us. A woman tied a rope around herself while a man at the cliff top held the rope. She made her way down to save us.
My parents were relieved(宽慰的) that I was unhurt, but they were angry that I had done such a risky thing. I apologized and promised that I would not do anything like that again.

A.spring B.summer C.autumn D.winter

A.引导 B.期待 C.探索 D.检查
(　　)24.How did the writer feel about what he had done
A.Surprised. B.Sorry. C.Excited. D.Glad.
