根据下面一篇短文的内容判断下列句子的正误,正确的用"T"表示,错误的用"F"表示。

 Miss Grey lived in a small house. She was old and did not like noise at all, so she was very pleased when her noisy neighbor moved out. A young man moved in and Miss Grey thought the man seemed to be quiet.

  But at three o'clock the next morning, the noise of a dog woke her up. She thought she had never heard a dog there before. It must be the young man's dog. So she telephoned the young man, said something bad about the dog and then hung up the telephone before he could answer. Nothing more happened until three o'clock the next morning. Then Miss Grey's telephone rang, and when she answered, a voice said, "You telephoned me twenty-four hours ago. Now I've rung you up to say that I haven't a dog."

小题1:Miss Grey felt sorry when her noisy neighbour moved out.

小题2:Miss Grey's new neighbour was as noisy as the old one.

小题3:Some noise woke her up in the early morning.

小题4:She thought the new neighbour had brought a dog with him.
