5 . As you grow up, your parents are also getting older. "I don't want you to get old," you might say that to your mom and dad. But getting old is a normal (正常的) thing. Everyone will be old one day.

What's it like to be old? When you're with your grandparents, you may see wrinkles (皱纹) on their faces. Their hair might be gray. They need to wear glasses to read. They often lose things.

Old people are full of wisdom. They know lots of things and can give advice (建议). When people get old, they stop working. Think about your grandparents. They have a lot of time to do the things they like, such as traveling, reading, singing or going to school for the old people. That sounds great! They also have many stories of their lives, both good and bad. Do your grandparents like to tell you their stories?

How do you feel about getting old now? Do you still think it's bad to get old? Maybe different people can give different answers.

6 . People can’t eat or drink on the subway（地铁）in Beijing. This rule started on May 15.

Some people say it is good. Because if people eat on the subway, it will be full of the smell of food. That’s too bad. Eating on the subway also produces rubbish（产生垃圾）.

But others say it is bad. Some people live so far from their work places. They have no time to have breakfast before they go to work. And some people may get sick（生病）if they can’t eat in time.

Chen Yanyan, a teacher from Beijing, says we should think about（考虑）these people. They want to eat or drink on the subway. We should learn from many subway stations in Tokyo. “They have a special（特别的）place. People can eat and drink there.” She told Beijing Evening News.

7 . In the US, people are celebrating Arbor Day today, the last Friday in April. This holiday encourages(鼓励) people to plant and care for trees.

Not just the US thinks trees are important, other countries, such as Korea and South Africa, celebrate national tree days for a week! And India has a national planting(植树) festival every July.

Why do so many countries think trees and plants so important? What’s so important about trees? Trees make oxygen(氧气), which we need to live. Tree leaves also clean the air keeping us healthier. Trees also help stop dangerous and slides(滑坡) and they can even help stop water loss.

Trees are very important for city life, too. For example, if there are many trees in a place, there are fewer crimes(罪犯). And living near “green spaces”(parks with trees and plants), there will be fewer sick children.

Finally, people believe that spending time with trees in nature can help to relax and also make the stress lower. Some even call this “forest showing”. The time with green trees may even improve one’s immune system(免疫系统) and make our body stronger.

So maybe you should put your arms around a tree today — or at least sit quietly under one!

9 . Many people likes to travel(旅行) by plane, but I didn't like it because an airport(飞机场) is usually far from the city. You have to get there early and wait for(等待) hours for the plane to take off(起飞) and it is often late. You can't open the windows. You can't choose the food. Planes are fast, but it takes hours to go out of the airport and into the city.

I like traveling by train. I think trains are safe. Railway stations are usually in cities. When you are late for the train, you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.

I also like cars. You can start your journey(旅行) when you want to, and you don't need to get to a railway station or a bus stop. Also you can carry many things with you in the car. But sometimes there are too many cars on the road.
