I was feeling a little blue because my mother had lost her job.

    One day, while I was1on the street, I heard the piano music and singing rising above the noise of the people. I walked more slowly to2where it was coming from. Then I saw a young lady sitting at a piano.

    She was singing songs about love,3 yourself and keeping on trying. The way she was singing made me a little comfortable. I stood there 4, watching her playing on such a crowded New York square. I thought that she must be 5enough to perform in front of so many people. She noticed me. I walked over and told her how good her6sounded. "Thank you," she said.

    "I have been going through a hard time recently, 7 you've made me hopeful again." I said to her.

    "I'm glad that I could help," she replied. "Why are you so 8?"

    "Well, my mum has lost her job, and I'm not sure what to do…"

    "Did you noticed the9you were walking? Your head was down," she said. "Don't be upset, because 10 comes in different ways and if your head is down, you might not see it. You should11more…lift your head up."

    I looked12her, amazed at how she was encouraging(鼓励) me. "13are you playing the piano here?" I asked her with a smile. She14that she saw a lot of unhappy people in the world and she tried to cheer15 up by playing music.

    I smiled a little wilder, realizing that no difficulties could stop me from going on.

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

I like traveling by train. I think trains are safe. The stations are usually in cities. When you are late for a 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 trip 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 a car. But sometimes there are too many cars on the road. 

A new rubbish sorting system(垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing. Local people not only sort their rubbish，but also put QR codes(二维码) on it. 

"When the rubbish is collected and the codes are seen，I will get reward points to exchange for small gifts and even some money，"one of the local people told reporters. "It's really creative and encouraging. "

This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example，Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly. 

China produces quite a lot of rubbish every year. Much of the rubbish is buried(填埋) in soil or burned without being sorted. Landfills take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting，we can reduce the use of landfills and air pollution. 

What's more, rubbish sorting saves resources, which could bring economic benefits(经济利益). For example，a ton of waste paper can be reused to make about 850 kg of paper，saving 17 trees and 50 percent of water. Because of their benefits，some countries have developed successful sorting systems. 

Japan has a strict and detailed system. When people throw away a water bottle，the cap，the wrapper(包装纸) and the bottle itself have to go into three different bins. Every year，families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish. 

In Australia，every family is provided with three rubbish bins—the red lid(盖子) bin for "general waste" like food and plastic bags，the yellow lid bin for "recycling" like steel and glass，and the green lid bin for "green waste" such as grass and leaves. On the streets，the bins are printed with pictures of the things that are allowed inside. It takes recycling quite easy. 

Making new friends can be difficult, especially if you are a child in a new neighborhood. It may seem like everyone else has a friend to sit with or to talk to. Don't worry:if you're a nice person, you can make friends, too. 

Step 1. Decide what kind of people you want to play with. Choose (选择) wisely, because you'll probably become like them. Pick children that are nice to other people. 

Step 2. Smile and say something nice to the person you want to be your friend. If you like a person's shoes or think a girl is good at basketball, just say so. Everyone likes compliments. 

Step 3. Join clubs and teams. If you like sports, try out for some. Put yourself in situations where you are around many children that enjoy the same activities as you. It's easier to develop (发展) friendships when you have the same hobbies. 

Step 4. Ask questions whenever it's appropriate(适当的). People love to talk about themselves. Be careful not to ask too personal questions or ask someone too many questions. But asking one or two questions shows you're interested in him or her.
