{#blank#}1{#/blank#}This invention was invented by a 15-year-old boy with the help of his grandmother. Then he could stay outside and skate longer with his friends. His cars were warm and comfortable.

{#blank#}2{#/blank#}Many people believe that the first one was invented by 18-year-old Blaise Pascal in 1642 to help his father count taxes. It was used to add and subtract（加减） numbers. About 50 were made but they were not very popular 300 years later, they finally became popular. They have been popular ever since.

{#blank#}3{#/blank#}This invention helps people read, write and do "close work "after the age of 45. Without them, the world would be difficult for the people above 45.

{#blank#}4{#/blank#}Since it was invented, it has been recording the history of the world. It's also convenient for us to take some pictures about the unforgettable and amazing moments in our daily lives, and even keep them forever.

{#blank#}5{#/blank#}This invention can help people in the street. It looks like a tree standing beside the street. It directs（指挥） cars and trucks. Without it, the traffic would be terrible.

As Picasso once said, "Every child is an artist. The problem is how to remain an artist once he grows up." For{#blank#}1{#/blank#}(多的) people, this is true. We{#blank#}2{#/blank#}(可能) have painted, written, or played an{#blank#}3{#/blank#}(乐器) as{#blank#}4{#/blank#}(孩子). However, as adults, it seems that{#blank#}5{#/blank#}(没有人) remembers his dreams of being a{#blank#}6{#/blank#}(电影) star or a musician. But is being creative really all that{#blank#}7{#/blank#}(重要的)?

The answer is yes, and it really {#blank#}8{#/blank#}(要紧). According to studies, {#blank#}9{#/blank#}(可能) being creative can help fight against negative emotions. It is a good {#blank#}10{#/blank#}(方法) to build problem-solving skills, and convey(表达) a {#blank#}11{#/blank#}(信息) of being confident. One study even found that creative people {#blank#}12{#/blank#}(活) longer because their brains are more active.

How can you become more creative? Try taking a child's way. Pull out a {#blank#}13{#/blank#}(笔记本) or a piece of paper and {#blank#}14{#/blank#}(仅仅) draw or paint, with no goal in {#blank#}15{#/blank#}(脑海). This gets all {#blank#}16{#/blank#}(种类) of connections in the brain working. Or you can get some exercise in the {#blank#}17{#/blank#}(早晨). A study discovered that a tired mind can be a more creative mind. So, hit the gym, go for a running {#blank#}18{#/blank#}(比赛) or climb a {#blank#}19{#/blank#}(山), and then sit down to try something new.

One of the{#blank#}20{#/blank#}(主要的) obstacles(障碍) to being creative is called "fear of failure." In other words, some people think they will{#blank#}21{#/blank#}(产生) a{#blank#}22{#/blank#}(数字) of{#blank#}23{#/blank#}(错误) when trying something new, so they just don't try. In fact, making mistakes is{#blank#}24{#/blank#}(没什么) serious. Don't be{#blank#}25{#/blank#}(紧张的). It is{#blank#}26{#/blank#}(必要的) to{#blank#}27{#/blank#}(学习) to change what "failure" means in your own mind. You might think failure is painting a picture that you see as ugly, but don't{#blank#}28{#/blank#}(丢失) your confidence. What if "failure" was actually not painting anything at all?

How can you remember a song for a long time? Why does your teacher use songs to teach you English? There is a scientific reason for this. 

Researchers (研究者) are studying the relationship between music and remembering a foreign language. "Singing could be a new way of learning, especially for a foreign language. The brain likes to remember things in a catchy (悦耳易记的) and relaxing way. For example, children can remember difficult words quickly when they are in a song," said Dr. Karen Ludke. If children find it difficult to learn foreign languages, this new way may help. On his blog (博客), Dr. Ludke wrote "A listen—and—repeat singing way can help to learn foreign languages and open the door for future research in this area."

Many language teachers know the importance of music and they often use it in teaching and learning. Hua Zhuying, a teacher at a Chinese language school in Washington DC, likes using songs in teaching Chinese. She said, "I use music all the time to teach children Chinese. For little kids usually we use English songs but teach them the Chinese lyrics. Not only does it work, but it is fun for children. Sometimes I think if I learned English that way when I was young, maybe I could speak English much better."

Our brain likes music in learning languages, especially for remembering. If you are still having problems in learning a language, why not try singing it out?

Do you like reading books? Some people may say yes. Reading is a good habit(习惯). They think reading is interesting. In Beijing, you can see some sharing(共享) bookstores. You can read and borrow(借) books there. But you can only get two books once(一次).

Readers can use their mobile phones to borrow some books. Then they can take these books home. But they must give a deposit(押金) of 99 yuan. There are many books in the sharing bookstores. People can keep these books for 10 days and they don't need to give the sharing bookstores money(钱). After they read books, they must return them to the bookstores. Then they can get one yuan as a reward(奖励). 

Now there are many sharing bookstores in Beijing. The bookstores want people to read more books and give people lots of fun. More and more people are interested in reading now.

Here are some cartoon characters．Let's have a look．

I want to become a doctor in the future. 

I think that being a doctor is one of the most important1 in the world. Most people are busy working every day. They don't have much2 to relax or do exercise. Lots of them are in3 health because they don't4 themselves. I would like to help them get healthy again. 

I know it's5 to be a doctor. I need to learn a lot. I am going to study hard to6 my skills. As a doctor, I am going to try to help the people who are ill. I'll always be there with them when they7 me. If someone doesn't have enough money, I am still going to8 him or her. I believe after he or she gets some money, he is going to9 the money back to me. Maybe doctors can't make much money, but I don't care. 

It would be10 to be a doctor because I can help others. Helping others would make me happy.
