Though very cold temperatures continued to trouble the US in January this year, an act of kindness warmed everyone. In Chicago a young man provided a homeless old man with the proper footwear—from his own feet. Jessica Bell, a passenger, saw everything and posted the story on Facebook.

    According to her Facebook post, Bell was taking the train home on Friday when she noticed a homeless old man sitting across from her. Bell wrote that the man was wearing tattered shoes, and many pairs of socks to keep his feet warm, but there was blood seeping (渗) through.

    On the same train was another man. According to Bell's description, he was young, carrying a bag and a suitcase. He was wearing big black snow boots (靴子), which looked new and expensive. They were built for a Chicago winter. Then he did a good thing.

    Bell described that the young man took off his own boots and passed them to the old man. He opened his suitcase and gave him a pair of socks as well. Then the young man put on a different pair of shoes—not as nice as the ones he had given away. He told the old man to try them on and helped him clean his feet and change into the new boots as quickly as he could, and then left the train.

    At the end of her post, Bell wrote. "I love my city. I love that in a time and place where a quiet act of kindness appears without warning." The story has received thousands of comments (评论), with many people describing how moving they found the act of kindness. One wrote, "We can all learn from that young man." Others are thanking Bell for sharing the story—there are still good people in the world.

Dear Frank,

    Thank you for your postcard. I'm very glad you are having a good trip now. Ottawa is very beautiful in May. I hope I will have a chance to go there one day.

    Our summer holiday will start next month. I enjoy my summer holiday, although(虽然)it's hot at that time in America. During the summer holiday, I can swim in the sea and go fishing. It's so cool. And I am going to our hometown near Chicago with my sister Linda, and my parents agree(同意). Our uncle lives there, so Linda and I can stay with him.

    We are not going to take a plane. We are going there by train. I am going to fish there. And Linda likes painting. She is going to do some painting there. I'm sure we'll have a good time.

Sincerely,

Jack

I have always admired students who hand their homework in on time and never forget anything important to do. Me, on the other hand… I'm terrible at getting myself organized! The following tips are from my friends.

Drones（无人机）are like planes, but come in many shapes and sizes. They have no pilots and are controlled from outside the drones. During these years, they have been used to attack（进攻）enemies or moved goods（货品）in dangerous areas. 

Now small drones are part of people's lives. For example, people use drones to take photos or make videos. Besides, a drone delivery（n.投递）service has proved（证明）successful. 

Online store JD can use drones to deliver small packages（包裹）. It has built several drone stations so that it can load（装载）and deliver（v. 投递）its packages. 

Drones have made our shopping experience different. We can order a new coat in the early morning and it will be delivered before we finish breakfast. 

Bizzby Sky, a UK company, has created a delivery service for small goods. Open a smart phone app, enter your address, set a time and pay enough money for the delivery service. Then in minutes, a drone will do tasks for you. 

However, any drone company needs government permission（允许）to fly its drones in many countries. We believe we will see more and more drones with goods fly in the sky very soon. 

Our schooldays are the best and happiest days in our life. We should learn not to waste this wonderful time. 

Be positive (积极的). Don't say things are difficult or boring. We should be interested in the school life and school subjects, such as Chinese, maths and so on. We should join in lots of activities. We will enjoy ourselves very much. If we want to have a rest from schoolwork, we can go to some public places to do volunteer work (义工). 

Keep healthy. We need to have a good breakfast so that we won't be hungry in class. If we go to bed late, play the phone until (直到) midnight and don't get enough sleep, we will feel sleepy in class. In order to keep our body healthy, we should also do some sports. 

Study hard right now. Some students always say that they will study hard tomorrow. It is important to study today and the following every day. Everyone wants to be the first one to get to the top of mountain. In fact, if we fall behind, it will be very difficult for us to catch up (赶上). 

Don't be too disappointed (失望) if things sometimes go badly wrong. We should always believe that we are the best.
