The college entrance examination is just around the corner. Homework and tests will keep many of you up late at night, and you may plan to make up for your lost sleep during the weekends. {#blank#}1{#/blank#} is it useful? A study published in the journal Current Biology completely has changed {#blank#}2{#/blank#} people used to think. It shows that the habit of sleeping in on weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}3{#/blank#} (bad), it may damage your health.

Earlier this year Rodney Smith Jr. made headlines when he drove eight hours from his home in Huntsville. Alabama, to cut the lawn for an elderly soldier in North Carolina who couldn't find anyone to help him with his yard work.

That wasn't the first time the twenty-nine-year-old Bermuda native had gained such attention. To do his good deeds, Rodney often finds leads for those in need through social media.

Back to one August afternoon in 2015, Rodney Smith Jr. was driving home. That's when Rodney saw an elderly man struggling to mow his lawn. He would take a couple of shaky steps, using the handle to stabilize himself, pause, then slowly push the mower again. Rodney decided to help. Mr. Brown thanked him greatly, and Rodney went home feeling satisfied.

Sitting at his computer to do his homework, Rodney couldn't get Mr. Brown out of his mind. There must be many Mr. Browns out there. He went online and posted that he would mow lawns for free for senior citizens. Messages flooded in.

One day a cancer-battling woman said she wasn't having a good day. Rodney decided to do more than mowing lawns. After he finished mowing, he knocked on her door. "You're going to win this fight, Madam", he said. Then he asked folks to pray for her on social media.

Word of Rodney's mission spread. A grandmother in Ohio said he'd encouraged her 12-year-old grandson to mow lawns. He got a letter from a seven-year-old boy in Kansas. "Mr. Rodney, I would like to be a part of your program, and I'll make you proud," he wrote.

That gave Rodney an idea. In 2017, he decided to establish a programme Raising Men Lawn Care Service to make a national movement for young people. The kids learn the joy of giving back.

Yard work seems like a small, simple thing, but taking care of the lawn means a lot to the people they do it for. "When we mow their yards for free, they can use the money for healthcare and food etc. It means more than you would think," Rodney said.

One teacher had two students. One of them had a positive vision while the other had the 1 one.

One day, the teacher 2 for a park with both the students and while wandering in the garden, they 3 a mango tree from which some ripe and juicy mangoes were 4 . On seeing this, the teacher thought to 5 both of his students. Then, he asked the first one, "My dear child, what do you think of this mango tree?"

The student answered instantly, "Teacher, in spite of people 6 this tree with stones, it gives us sweet and juicy mangoes. It does 7 but still it gives us fruits. I wish all human beings learn this important 8 from the mango tree-to share their 9 even if they have to suffer for this."

After that, the teacher asked the other student the same question. The student 10 answered, "Teacher, this mango tree is no good and will not give mangoes by itself but only when we hit it with stones and 11 . Therefore, we should hit it hard to get sweet mangoes from it. That is the only way to 12 these mangoes. It is also clear from this tree that in order to get good 13 from others, we need to be violent and only when we become violent, then and only then will we get 14 ."

The teacher was delighted with the answer given by the first student because he had an admirable vision and 15 the tree with positive vision.

 "BANG!" I pulled the door heavily behind me. "Never set foot in this house again!" stormed father. I rushed out of the flat and ran along the street.

A young man who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree. But now...I don't know whether it is because I have grown up or because Dad is getting old. We differ in our ways of thinking. We are just like two people coming from two different worlds. It feels like there is an iron(铁制的) door between us that can never be opened.

I wandered in the streets, until I had only the street lights to keep me company. My heart was frozen on this hot summer night. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.

I thought to myself, "Is Father waiting for his boy, or still angry with him?"

All the lights were off except Father's.

Dad was always like this. Maybe he didn't know how to express himself. After an argument he had the habit of tucking me underneath the covers(掖被子) while I was sleeping. This was how he always was. He had been a leader for so long that telling everyone else what to do had become his second nature.

The light was still on.

"Am I wrong?" I whispered, maybe... With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my cheeks. I suddenly realized that the iron door that I had imagined between us did not exist at all. Love——it's second to none.

Zhang Guimei taught at a school during the day and took care of a children's home in her spare time. One day, Zhang met a teenage girl {#blank#}1{#/blank#} told Zhang that her family was too poor {#blank#}2{#/blank#} (afford) school fees. Zhang went to persuade her parents to allow their daughter to continue schooling {#blank#}3{#/blank#}, the parents refused Zhang. With the little girl lingering in her mind, Zhang tried to figure out how to help those poor local girls.

In 2007, Zhang {#blank#}4{#/blank#} (elect) as a representative of the 17th National Congress of the Communist Party of China and attended the meeting in Beijing. A news report on Zhang helped her ambition of building a school {#blank#}5{#/blank#} girls gained the attention of Huaping county officials and other {#blank#}6{#/blank#} (support). A year later, Huaping Girls' High School, China's {#blank#}7{#/blank#} (one) tuition-free high school, opened and enrolled 100 students, with Zhang as its president. Most of the girls were from remote areas.

{#blank#}8{#/blank#} (follow) in Zhang's footsteps, many of the graduates of Huaping Girls' High School have chosen to work in remote areas.

In July 2021, she was one of the recipients of this year's July 1st Medal, the {#blank#}9{#/blank#} (high) honor for a Communist Party of China member, for her outstanding contributions to education in the {#blank#}10{#/blank#} (mountain) region.
