      Last week, I went to the countryside to visit my grandmother with my sister. My grandmother is 80 years
old now but she is very healthy. She was glad to meet us. After talking with us for a while, she went to the
kitchen to cook lunch for us. When I was hungry, she came out with a large bowl of soup and two plates (盘)
of salad. The soup was made of carrots and potatoes and the salad was made of different kinds of fruits and
vegetables. I felt a little disappointed (失望的) because I liked meat not vegetables. But I still had a try at the
soup. To my surprise, it was so delicious. I tasted the salad. It was also nice and fresh. Then my grandmother
showed me her garden. It was not large but full of fruits and vegetables. My grandmother told me happily,
"What you ate just now all comes from my garden. I think it's a good idea to plant (种植) something here."
