1970 was World Conservation(保护) Year. The United Nations wanted everyone to know that the world was in danger. They hoped something could be" done.

    Here is one example of the problem. At one time there were 1,300 kinds of plants, trees and flowers in Holland(荷兰), but now only 866 are left. The others have been destroyed (毁灭) by modern people and their science. We are polluting earth, air, water and everything around us. We can't live without these things. If things go on like this, we shall destroy ourselves.

    What will happen in the future? Perhaps it's more important to ask "What must we do?". More and more young people have known this. Many of them are helping to save our earth. For example, they plant trees. In a small town in the United States a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conservation through a song called "No one's going to change our world". It was made by Cliff Gichard and other singers. The money from it will help to conserve tigers, elephants and pandas on the earth.

    Squirrels (松鼠) are getting ready for winter. They are looking for nuts and seeds, digging holes in the ground or finding holes in trees. That's where they store the food they will need during the coming months, when the weather is cold and sometimes snowy.

    Squirrels spend a lot of time in trees, which are like restaurants for them. Among their favorite things to eat are nuts and other parts of trees, like tender buds (花苞).

    Squirrels may also eat corn, insects and other animals. And, as anyone who has a bird knows, squirrels love bird food!

    Squirrels stay active all winter, so they need plenty of food to help keep up their energy. Squirrels tend to bury food underground, piece by piece. Some squirrels may gather food into piles that they put at the base of trees or bury underground.

    When they need food, squirrels use their memory and smell to help them find what they buried. Sometimes, you'll even see them digging through the snow.

    Squirrels make nests in trees. Some squirrels spend much of the winter in underground tunnels (地道), where it is warmer.

    When spring comes, squirrels change their eating habits to new plant growth, like buds and leaves. Sometimes they forget to dig up all their buried nuts.

    That's why you'll sometimes find a little tree growing in a place where neither you nor your family planted it. It must have been the squirrels.

Dear Jenny, 

You ask me about my favorite festival. It is Spring Festival. It is1 January or February. For the festival, we do many things and buy many things,2 we are always busy. The color of Spring Festival is3 . We wear new red 4  and put up (张贴) red paper-cuts (窗花). And we put lucky money in red packets (红包).5 are always happy those days because they can get lucky money from6 parents, grandparents, uncles and aunts. What do we usually

7 on Spring Festival? Jiaozi. In the8 , the family will watch TV together but children don't like watching TV for 4 hours. It's really9 for them. They always play fireworks10 their friends.

What about you? What festival do you like best?

Your friend,

Li Ming

In our lives, we have to get on with the people around us. Being a decent (得体的) person will help us form healthy relationships. Here are some useful suggestions on how to be a decent person. 

Let others trust you. Keep up with your promises. If you promise to be somewhere at a certain time, be there. If you say you'll do a favor, do it. Decent people follow through because they want others to feel safe. People need dependable friends and family members to have a sense of safety in their lives. 

Avoid judgment. Remember, you cannot fully understand what it's like to be inside someone else's head. Therefore, avoid trying to pass judgment on a behavior or a decision. Everyone is different. So, it should not be surprising if another person's choice is different from yours. It's okay to put yourself in someone else's shoes and try to understand their decisions. 

Provide support during bad times.Think about times in your life that were hard. You probably had friends, family members, and other loved ones helping you along the way. If you want to be a decent person, you should provide support in return. When people go through difficult times, put yourself out there and help. 

Let go of anger. If you live with a lot of anger, you're more likely to be unfriendly to others. Becoming a decent person often means letting go of some anger. If you find yourself becoming angry, take physical means to cool down. For example, take a deep breath. Always remember to avoid taking things personally. This will help you away from your anger.

 Recently, 76% of people between the ages of 65 and 74, who took part in a survey, said they used social media, compared to 40% five years earlier. An increase in social media use was also seen among people aged 75 and over. A growing number of elderly people are active on social networks and are using the Internet to make calls.

 But how will you feel when you find out your grandparents are using social media? Many young people may think" Oh no! They' re going to see everything I post and start writing comments(评论)" and many others say" I'm going to have to spend hours teaching them how to use social media. It's troublesome". Once they have learned how to use social media, they may get a lot of fun. Take Amy for example. She is an 80-year-old granny who has over three million followers on a social media platform because of her sincere sharing on fashionable dressing and positive life attitude.

 Honestly, you should be happy if your grandparents are eager to join the digital worlds. Social media use can have a number of health benefits for the elderly. Nowadays families are more geographically distant than ever before, and social media is a great way to connect with faraway relatives and friends. While nothing replaces face-to-face communication, social media is a great way to keep in touch with family members. Another benefit is that elderly people can make new friends who share similar interests, or find long-lost friends from childhood. Finally, social media use can be very educational. For example, looking through Wechat news is a great way to stay informed and keep up to date with local and global events.

 Have your grandparents had a social media account yet? Have they asked you to help them create one, but you didn't care? Perhaps you should make the effort because it may affect their quality of life.

Do you wear glasses? If yes, would you like to have surgery(手术) so you don't need to wear them anymore? Many believe that surgery can fix the problem forever, but that's not always the case(总是如此).

Most people wear glasses because of nearsightedness (近视). When we see things, light comes into our eyes and focuses (聚焦) on the retina (视网膜). But for people with nearsightedness, in their eyes, light focuses in front of the retina. This makes things far away blurry(模糊的) but close things clear. 

Surgery can treat this. Xu Jiayi, a 19-year-old student from Beijing, had the surgery five months ago during the winter vacation. "After the surgery, I can see very clearly. Life is more convenient without having to wear eyeglasses," said Xu. However, the process (过程) is not as easy as you might think. Xu said that her eyes hurt badly right after the surgery. Also, she needed to use medicine for at least three months. "At first, there were four types of medicines, then the number became six, she said. These medicines help the eye heal(康复) and prevent eye problems.

Moreover, if you don't look after your eye health well, nearsightedness may return even after surgery. "Because I use my eyes too much both at work and at home, things have started to look blurry to me again," said Du Anni, 32, who had the surgery nine years ago.

Instead of fixing nearsightedness, "the surgery just lets you ‘take off your glasses'" said Wei Wenbin from the Beijing Tongren Hospital in a speech in July. He said that the surgery doesn't fix the changes in the eye's structure(结构).
