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.

Eric was a nine-year-old boy who lived with his single mother, Stacey and sister, Lily. They lived a hard life. Eric felt bad for their situation but worse for himself, especially in school.

Eric's leather boots were worn out. They didn't protect his feet from the rain, and his socks became totally wet as water went through the holes in his shoes. Stacey attempted to fix the holes but it was no use. Eric still walked to school with that pair of broken shoes. How much he wished he could also have new comfortable and expensive shoes his classmates wore!

One day, Eric returned from school and complained to Stacey, "It was raining today. Water has leaked into my shoes again. I hate my boots! Why can't you get me new ones?" Stacey was sad and helpless. "I spent our last savings on your sister's medicine. She's sick. Eric you know that. You need to act like a responsible big brother!" she answered. Tears welled up in Eric's eyes. "I hate you!" he shouted. "You only care about Lily! You don't love me!" Then he cried and ran to his room.

After preparing dinner, Stacey went to his room with his dinner plate. "I'm sorry, Eric," she whispered to comfort him. "We're going through a very tough journey recently. But I'll get you new shoes in the future." However, Eric refused to listen to her.

The next day, when Eric went to class, he took his seat quietly and hid his feet under his chair, as usual. He was embarrassed to show his boots. As the math teacher Mrs Fletcher entered the class, all the students greeted her. "Today, we have a very special friend with us," she smiled. "Everyone, please welcome Ben, your new classmate." Soon after, a boy with a pair of crutches(拐杖)entered. The new boy only had one leg. Eric was shocked. He and all his classmates thought how unlucky Ben was and that he must be very shy and sad.

Paragraph 1: At that moment, Mrs Fletcher asked Ben to introduce himself. 

Paragraph 2: Inspired by Ben, Eric realized he should appreciate what he had. 

Adults check their phones, on average,360 times a day, and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our emails or social media feeds, and suddenly we've been sucked into endless scrolling.

It's an awful circle. The more useful our phones become, the more we use them. The more we use them, the more we lay neural（神经的） pathways in our brains that lead to pick up our phones for whatever task is at hand-and the more we feel an urge to check our phones even when we don't have to.

What we do know is that the simple distraction of checking a phone or seeing a notification（通知）can have negative consequences. This isn't very surprising; we know that, in general, multitasking does harm to memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It's true for everyday tasks that are less high-risk, too. Simply hearing a notification "ding" made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task.

It isn't just the use of a phone that has consequences-its me re presence can affect the way we think.

In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible（like on a desk）, nearby and out of sight（like in a bag or pocket）, or in another room. They were found to perform far better when their phones were in another room instead of nearby-whether visible, powered on or not.

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.
