Madisyn Babcock from US is a high school student. She used to have thick blond hair and looked very beautiful. But at the age of 17, she suffered from a serious disease that causes people to lose hair. She had to face the challenges.

    Her senior photo shoot (高中毕业照) was coming, but Babcock didn't pity herself. She still wanted to nook beautiful in her pictures. She and her mother came up with a genius(天才的) idea--to paint some flowers all over her head. Her mother, an American artist, painted the flowers for Babcock.

    US photographer, Chelsea Taylor, took pictures of Babcock. "She has used this as an opportunity to show other girls how to love themselves and own their beauty--even if it isn't conventional," Taylor said. When life throws you a curve ball, it's important to have people that care about you by your side. So I think Babcock is also very happy and lucky!

    One day, Thomas Edison came home from school and gave a letter to his mother. He {#blank#}1{#/blank#} (tell) her, "My teacher gave this letter to me and asked me to give it to my mother only." His {#blank#}2{#/blank#} (mother) eyes were full of tears as she read {#blank#}3{#/blank#} letter out loud to her child, "Your son is a genius (天才). This school is too small {#blank#}4{#/blank#} him and doesn't have enough good teachers to train him. Please teach him {#blank#}5{#/blank#} (you)."

    Many years after Edison's mother had died, Edison became one of the {#blank#}6{#/blank#} (great) inventors of the century. One day, he was going through the old closet (壁柜) and he found a folded letter which {#blank#}7{#/blank#} (give) to him by his teacher for his mother. He opened it. The message {#blank#}8{#/blank#} (write) on the letter was, "Your son is mentally (精神上) ill. We cannot let him attend our school any more, he has to leave the school."

    {#blank#}9{#/blank#} surprised and excited Edison was after reading it! And then he wrote in his diary, "Thomas Alva Edison was a mentally ill child, but his mother turned him into the genius of the century {#blank#}10{#/blank#}(success)."

    Mr. Chen was puzzled（闲惑的）and a little suspicious（怀疑的）. He sat in the office and studied a letter apparently（看似）from Mrs. Wang, the mother of one of the pupils in his class. There was something about it which worried him.

    "I don't understand," he said to himself. He shook his head as he circled four mistakes in the letter. "Mrs. Wang is an educated woman. She wouldn't make mistakes like these even if she did write the letter in a hurry. "Mr. Chen took out his class register(名册)and said to himself, "Yesterday was Thursday. Let me see. Ah, yes. I thought so. David was absent on Thursday last week and the week before. Hm. Why is he so often absent on Thursdays? Was he really ill yesterday? Could it be a coincidence(巧合)?”

    Mr. Chen stared at the register as if the answers to his questions were hidden in it somewhere. Then he took out a copy of the timetable(课程表)for his class.

    "I wonder." he told to himself. "I wonder if his absence has anything to do with one of these lessons."

    Mr. Chen looked at the subjects for Thursday: Mathematics, English, P. E. He thought about P. E. He knew that the pupils had P. E. twice a week: once on Monday, when they usually played games on the school field, and once on Thursday, when they did exercises in the gym.

    Mr. Chen glanced round the office to find Mr. Long, the rather strict P. E. teacher, but he was not there.

    "I'd better have a chat with Long and David, "Mr. Chen thought.

The bell rang. "I can't do anything right now," Mr. Chen thought. "It's time to go to Class 2. I'll do it later on."

    Mr. Chen picked up his books and walked off to teach Class 2.

Later, on Friday, Mr. Chen spoke to Mr. Long, the P. E. teacher. Mr. Long agreed that it seemed strange for David to be absent so often on gym days. They thought about it for a while.

    "David is a good athlete(运动员)," Mr. Long finally said, "but he's afraid of heights. I was hard on him once because he wouldn't climb more than a couple of meters up the rope. Do you think that's why he's been absent recently?"

    "Yes, I think so," Mr. Chen said. "I'm going to talk to him this afternoon before he goes home."

    "Well, I've got a suggestion to make," said Mr. Long. "If he's scared of heights, he'd better come and see me after school. Quite a few people suffer from (遭受) vertigo. I'll be glad to help him."

    “That's very kind of you," said Mr. Chen. "I'll get him to come and see you on Monday or Tuesday."

    A few days ago, a baby in England saved(拯救) her mother by using a mobile phone. The baby named Amelia was only 11 months old. How could she save her mother at such a young age?

    On that day, the 20-year -old mother called Elizabeth became unconscious(晕倒) at home. At that moment, the mobile phone rang. Amelia, the 11-month-old baby picked it up and answered it. The phone was from Elizabeth's mother, Linda Wright. Linda heard "Who is that?" and "Mama" on the other end of the line. She knows that her daughter has a history of fainting(晕厥) and she also knows her daughter doesn't let the baby play with the phone. So she called 999.

    Elizabeth was in hospital when she woke up. The doctor said that she was all right after the examination(检查). Elizabeth was surprised to find herself in hospital. When she knew that Amelia had saved her, she said she was lucky to have her baby. "She is clever," Elizabeth said. "I am proud of her".

Imagine you are going to give a speech the next day.The night before, you spend a lot of time thinking about the possible mistakes you might make and whether you're prepared enough. Well, you might be overthinking. 

Overthinking means going over the same thought again and again, analyzing( 分 析 ) the simplest situations or events too much. 

According to The Conversation, overthinking comes from one of our primitive instincts(原始 本能). The primitive mind will always see things in the worst possible light.Our brains are always looking for threats(威胁), to make a plan to deal with those threats and keep us safe. 

Some people believe that overthinking may be helpful because it helps us look at a problem from every possible angle(角度) and get ready for what might happen. However, research suggests that overthinking can make us stressed, anxious(焦虑的) and depressed (忧郁的). 

What's more, overthinking might create problems with how you get along with others.As you think the worst, make incorrect guesses, or worry about every little thing others do and say, you might misunderstand their intentions(意图). 

So, instead of sitting and thinking about a problem again and again, you can distract(转移注意 力）yourself for a bit. Your brain might find better ways to solve the problem while you're doing something fun, like gardening(园艺), or even while you're sleeping. 

Also, when you find yourself overthinking, challenge these thoughts. Ask yourself if they make sense and think about other possibilities.It can be hard at first,but recognizing that you are overthinking can help you make a change.
