Betty likes the house  three windows.

Once there was a girl, named Kate. She was very polite and ready to help everybody. One day she found a pink paper bag on the way to school. She opened it and saw there was a lot of1in it. She thought she should hand it in to the teacher, so she2 it in her schoolbag.

When she went to the teacher's office, her teacher wasn't 3. As it was time for class, she hurried to the classroom.

After class, she told her friend, Mary, about the money that she4. Then, her greedy(贪婪的)friend took away the bag.

After school, Kate wanted to go to the5office again, but she found the money was missing.

The next day when the children were playing a game, Mary fell down and was hurt very badly. The other children stood around her and didn't know6to do. Kate kept calm and did something to stop the bleeding. She told the others to go to find teachers for7. Soon a teacher took Mary to the8and the doctor examined her carefully. Within a week she was all right again. Kate became very popular in the school.

Two weeks later Mary came to Kate's house. Her eyes were red. She was crying. She gave Kate the9paper bag with the money in it and said, "Kate, I have taken the money away. That day when you helped me, I felt very sad and now I decide to tell you the10. You are such a nice friend!11please don't tell the school about this!" Then Kate said, "You are now12, but you have done a bad thing. Though I will not tell anyone, I want you not to be greedy and 13 to do anything wrong. "The girl thanked Kate and 14.

At the end of the term, Kate was given a 15for being a very helpful girl in the school. Mary became an honest girl and was never greedy again.

Once wrong, never be wrong forever.

Everything you see around you was once nothing more than an idea in someone else's head. So, if you think you've got a genius idea, be prepared to start inventing things and get to market them. It's not as hard as you think!

The best part about inventing new things is finding out which of your problems, or other people's problems you'd most like to solve. If you can find a problem that hasn't been solved, or a way to solve a problem better, you've hit upon something you may want to achieve,

You need to find out if there are people willing to buy your product, if someone else is making or selling similar products and if your product can beat all others.

This is why you need to write down everything you can think of that relates to (与……有关) your invention, from what it is and how it works to how you will make and market it. This is the. first step in patenting (获得专利权)your idea and keeping it from being stolen.

You can't just say you have invented something useful if you don't have a prototype (雏形). At this beginning stage, don't spend too much money. In fact, if it's possible to make a working prototype from cardboard or paper, that's totally fine. If you do require a more professional prototype, use a 3-D printing company, or find a factory that you can afford.

You could license somebody else to produce, use or sell your invention. It could be the easiest way to make money from it. If you're someone who is great at sales, who can manage people well and who enjoys taking risks, starting your own business may be a better choice.

A. There are two ways to get your product to market.

B. Inventing a product means one thing: solving a problem.

C. Once you've come up with an idea, it's time to do some research.

D. Now you need to get a prototype made so that you can test it.

E. You should protect your ideas and invention.

What do you want to be when you grow up? (近来), as 'more and more people keep pets, a new job called pet photographer has been quite popular. Zhang Tianhang, a 33-year-old man from Beijing, is one of the most popular pet photographers in China.

Driven by his love for animals, Zhang studied photography at Nottingham Trent University in the UK, (尽管)his family weren't pleased with his decision. ""They don't think being a pet photographer meets their (标准)for a good job, "he said.

However, that didn't change Zhang's mind. In2010, he opened his photography studio (工作室), Inpetphoto, in the UK. After graduating(毕业)a year later, he returned to Beijing and (继续)offering photography services to pet lovers.

In the following years, he overcame many (困难)and founded his own company. Today, he has seven professional photographers and two studios in Beijing.

" (与……相比) people, pets are harder to control. They are always excited and like to (冲)around. Therefore, besides having a good eye for photos, you'll also need a great deal of patience (耐心)to consider the (感觉) of pets," he said. Besides taking photos for pets, his studios also offer training classes to pet photography lovers.

In the future, Zhang plans to set up more such studios in other Chinese cities, and (添加) more training classes and services." Today, pets are no longer just pets, but family members. For this, I (打赌)that the market will have a good future," he said.

The word photography was first used in 1839. However, at that time the subject had to keep still (静止的) while it was taken a photo of. Few people had ever tried to take photos of moving subjects. The first man to do so was Eadweard Muybridge, a world-famous photographer. He created the first moving picture.

When a horse is running, do all four hooves(蹄)ever leave the ground at the same time? That was the bet that a gentleman called Leland Stanford had with some of his friends. Most people believed that a horse always had one hoof on the ground, but Stanford didn't think so.

Because a horse's legs are moving so fast, it's impossible to tell just by looking. Stanford needed away to record the movement of a running horse. In1872, Leland Stanford offered Eadweard Muybridge $ 25, 000 to find the answer. Muybridge had no idea if he could successfully set up and perform an experiment to settle the bet, but he thought he should give it a try.

In 1878, after years of experiments, Muybridge got what he wanted. He had a sequence (连续)of 12images(图像), and one of them clearly showed all four of the horse's hooves were off the ground at the same time. In the end Muybridge collected his well-earned $ 25, 000 from Stanford.

Though Thomas Edison is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison's invention.
