1. 根据短文内容，选择正确答案。

Dear Linda,

    I'm very busy with my work. But my mother needs my key. She can't get into the house. Please help me take the key to her. It's not difficult to find my house. Now let me tell you how to get to my house.

    First, walk to the post office near our office building(建筑物). Pass it and go straight. Turn right at the traffic lights (交通灯), then you'll get to New Street. There's a bank on your left and then go down the street. Go through Green Street, High Street and River Street. Then turn left into Long Street. Go down the street and you can see a supermarket. My house is next to it. My mother will wait for you in the garden in front of the house.

    Thanks a lot. See you soon.

Yours,

Susan
