Every winter when the lake freezes over (冻结) for half the year, 80-year-old Lyubov skates across the ice wherever she needs to go.Lyubov has been using the ice to travel around her home for her whole life. As a child, she skated about 2.5 miles each way to school and back. She once fell through the ice and was luckily saved by her classmates.Lyubov lives alone now in a small house on the bank of Lake Baikal. Her children and five grandchildren don’t often visit her because they live five hours away by car. She has to look on a group of dogs, cows and chickens as her friends. Luckily, she has the ice to help her feel free! “For me, ice means being able to go everywhere,” the grandmother said.Every day, she skates half an hour to other villages to do her shopping. With temperatures often reaching -40 ℃, it’s hard for an old woman to live a normal life.

CCTV has reported that the food Chinese people waste every year is enough to feed 200 million people for a year. Chinese people are well known for being hospitable(好客的) and generous. Many even feel that they lose face if their guests have eaten all the food, because it seems that they haven’t prepared enough food for their guests.Luckily, the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives a sticker to the customers who have eaten all that they ordered. People can enjoy a free meal when they have 10 stickers. Besides, more than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their customers to take leftovers home.To reduce food waste is a big task, and it needs time.

It can help you develop a healthy attitude. A study shows that confident people are much happier. They may have more chances to succeed.
