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.

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.

Strategies to Overcome Self-Doubt Once and For All

Being self-confident is not easy and not everyone can do it, but it doesn't need to be that difficult. {#blank#}1{#/blank#}

Going through life can be very challenging at times. When we were young, no one told us how hard it will be in the future but here we are {#blank#}2{#/blank#} And it is unpleasing and can kill your confidence levels if not controlled from the beginning.

We will all experience some self-doubt, which is natural. {#blank#}3{#/blank#} It happens to us during normal days or whenever we are going to start a new job, a new task, or a new relationship, anything new in life will make you self-doubt. This sort of feeling puts you into dark days when nothing seems to go right and you might feel like giving up, and that is the time to be strong.

 {#blank#}4{#/blank#} Self-doubt is when you are unsure about one or more aspects of yourself. For example, when starting a new job, you might feel inexperienced or might think that you are not fit enough for the job, and this is a prime example of self-doubt.

 {#blank#}5{#/blank#} Low-level of self-criticism is actually good for you. It motivates you and pushes you to be better in life, to become greater than yesterday. This type of feeling will push you to work harder and faster than before and will also increase your productivity, but it should be a low level of self-criticism. You don't want to punish yourself over things that are beyond your control.

A. We needn't take it seriously.

B. It's impossible for us to deal with it.

C. One of the big problems of adult life is having self-doubt,

D. Self-doubt isn't all that bad, let us tell you why.

E. Let's explore to find ways to remove self-doubt forever.

F. It will take long for us to solve this problem.

G. There are some people mistaking self-doubt for something else.

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.

The popularity of ancient towns in the south of the Yangtze River, such as Zhouzhuang and Wuzhen, has aroused a nationwide trend in the construction of ancient towns. Lin Peng, the director of China's Institute of Ancient Cities and Cultural Studies, pointed {#blank#}1{#/blank#} that there are more than 2,800 developed or developing ancient towns in our country, {#blank#}2{#/blank#} is definitely the highest number globally.

In ancient towns, {#blank#}3{#/blank#} immersive（沉浸式） experience being mentioned here is historical and cultural characteristics—the "ancient" of ancient towns. Apart from visible "special buildings", characteristics also include invisible "culture". Tourists in ancient towns want to see the living {#blank#}4{#/blank#} （condition） of local people, feel the vitality of town life, try characteristic local snacks {#blank#}5{#/blank#} （influence） by geography and folk customs, and understand how long history {#blank#}6{#/blank#} （shape） local culture. Out of modern fast-paced work and life, tourists want to awaken their inner softness with a slow-moving ancient town.

Touring ancient towns is for recreation, relaxation, and pleasure, {#blank#}7{#/blank#} if all the ancient towns in different places are the same and cannot find their own {#blank#}8{#/blank#} （unique）, then ancient town tourism will {#blank#}9{#/blank#} （eventual） decline. Let every ancient town become a unique historical imprint（印记）, so that tourists can find their "poetry and distance" while {#blank#}10{#/blank#} （wander） through the ancient towns. This is the soul that ancient towns need to regain.
