二．阅读理解。
I am Cathy Brown. I am from America. I am working for the Sunshine Travel Agency(旅行社) in Changsha now.
Last week I took a group of French holiday-makers for a week’s trip to Taiwan. We traveled all around the island(岛). It is very beautiful. There are a lot of places of interest. My favorite place is the Sun and Moon Lake. You may ask why people call it so. If you fly high up over the lake and look down from your plane, you will find the answer yourself. In the middle of this lake, there is a small island. People call it the Pearl Island(珍珠岛) because it looks like a pearl. On one side of the Pearl Island, the lake looks like a sun, and on the other side, it looks like a moon. That is why people call it the Sun and Moon Lake.
There are many mountains around the Sun and Moon Lake. One of the most famous ones is the Ali Mountain. We stayed there for three days. We also had a dance party with Gaoshan people. On our first day there, we watched the sun going down slowly in the west. On our last day, we got up early and saw a very beautiful sunrise(日出).
Taiwan is a wonderful place to visit.
根据短文内容，判断下列句子正(T)误(F)。
( )1.Cathy went to Taiwan with some Americans last week.
