1. 阅读下列短文，从下面每小题的A、B、C、D四个选项中选出最佳选项

    When I was a kid, I often played basketball. So I was thin but healthy. When l was about 15, I stopped playing basketball. I also started to drink a lot of drinks high in sugar and eat much more than before. Between 15 and 17, I put on a lot of weight-about 50 kg.

    I didn't know how big I was until I saw a photo one day. In the photo, I had a fat neck and my stomach was out there. I hated the way I looked. I knew I needed to lose some weight.

    I started to drink only water, and eat less and healthier. I ate mainly vegetables and only one piece of meat every day, and stayed away from sugar.

    I also started to exercise. Every day, I ran for 30 minutes first, and then I did some push-ups (俯卧撑) for 10 minutes. I also jumped rope for 15 minutes every day.

    I kept exercising the whole winter. When March came, many people said to me, "Oh, Dave, you've been a different person!"

    It was true. I had lost 25 kg in three months. I liked taking photos, and I noticed the difference in my looks.

    I loved the three months. It felt good to lose weight, and it felt even better to set a goal (目标) and go for it.
