第三部分：阅读理解（共20小题；每小题2分，满分40分）

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

When I was a child , I remember that my mother decided that we would take a trip to visit my Aunt Sandy who lived in Mammoth Lakes, California. I was about 7 at the time but my memory does not fail me because I can recall my personal details .

We were sitting in the kitchen getting ready to have peanut butter and suddenly without warning the room started shaking. I remember thinking that it was weird(怪异)that construction workers must have been moving the house or something, but that it was weird that they would do it when we were still in it. I had a vivid imagination too. So everything started shaking and my aunt had this horrible look on her face as she dropped the knife of peanut-butter onto the ground and held on to the counter. My mom told me to get under the table, which as I think back was odd because what was happening was from the ground so what good was getting under a table going to do. The kitchen window soon broke out on its own from the force of all the shaking and I started getting pretty scared(害怕). I don’t think my aunt moved the entire time. My mom had gotten under the table with me and was holding me to make sure I was OK I suppose. It seemed strange because no one really knew what to do.

So finally the shaking stopped. The power was out and it took minutes before anyone really even started to move and talk again. My mother decided that we would leave the next morning. I don’t remember if we were only planning to stay for one night or if we were just stopping by on our way to Fresno where my mom had friends.
