Proofreading 2 (2018 课标全国 I) During my last winter holiday, I went to countryside with my father to visit my grandparents. I find a big change there. The first time I went there, they were living in a small house with dogs, ducks, and another animals. Last winter when I went here again, they had a big separate house to raise dozens of chicken. They also had a small pond which they raised fish. My grandpa said last summer they earned quite a lot by sell the fish. I felt happily that their life had improved. At the end of our trip, I told my father that I planned to return for every two years, but he agreed.
