1. 根据材料内容，选择正确答案。

    TWO English phrases show what people think about mice and rats: "As quiet as a mouse", and "a dirty rat".

    People think rats are dirty because they live in sewers(下水道) and other unclean places. They also carry diseases(疾病). Having a rat in your house is bad news. They smell terrible and make a lot of noise.

    Calling someone a "rat" in English means they are not to be trusted(信任). Saying "Rats!" is also a way to show that you are angry.

    Mice, on the other hand, are seen as quiet and cute. They live in fields and as unwelcome guests in people's houses. They are small and often kept as pets. Walt Disney's famous character Mickey Mouse helped make them lovable to children. Jerry, from the Tom and Jerry cartoons, is smart and naughty. It makes everyone happy.
