Today is Saturday. My boyfriend and I decided to get some exercise at Tsinghua University.

At first, we tried to play badminton but it was a little too windy. So my boyfriend decided to run while I did the ninth set of radio gymnastics. We were both exhausted after we finished. 

We ate lunch at a fast-food restaurant. He had a hamburger with chips and a cola to drink. I had the same but with mango juice.

After we finished lunch, we walked to a supermarket to buy some fruits and vegetables. We bought apples, bananas, strawberries and Chinese celery, tomatoes, potatoes, garlic and ginger. We also bought beef, eggs and bean curd.

We rode bicycles back home. He is now busy cooking beef and tomato soup for dinner. He is a great cook. This is just one of the reason why I love him so much.

(or) "I caught over thirty fish." is what I would suggest. </em><em>I hope this helps.</em>
