阅读理解。 Don't open the door to strangers It was Sunday afternoon. My brother and I were at home. My parents had gone to a party and asked me to look after my brother. Suddenly the doorbell rang. Ding-dong! My brother thought that it was our parents, so he opened the door quickly. A tall man wearing a black raincoat stood outside. He asked if we would like to buy some storybooks. I said no. when I wanted to close the door, he suddenly pushed the door very hard and came into our house. He took out a knife and asked me to tie up (捆起来 ) my brother’s hands with a rope. I tied up his hands in a special way so my brother could unite (解开) himself easily. The man then tied my hands and locked both of us in the kitchen. Then, he went to look for money. I taught my brother to untie the rope. He then untie me. We got out of the house through the kitchen window and went to the nearest pay phone to call the police. Soon the police came and took the man away. My parents were glad we were not hurt. They told us that we should not open the door to strangers. I learned a lesson about safety. 根据短文内容，判断下列句子正误。正确的用A表示， 不正确的用B表示。 (     )1. The man was a book seller. He came to sell books to the brothers. (     )2. The man locked the brothers in the kitchen.
