Luis and his wife Gloria need a house with at least three bedrooms. They also want to have a yard for the children to 1 in. And so far they have looked at several houses that are for sale. Their 2isn't going well, so they can't afford an expensive house. That's why they 3 for one that doesn't cost a lot, and, of course, that's not 4 to find.

Yesterday, they looked at four houses, and three of them were great. But they couldn't afford the houses they liked, and they didn't like the one they could afford. The only affordable one was old and had cracks (裂缝) in the5. Last night, Luis and Gloria talked about the house for two hours. "I know we didn't find anything that costs 6, but I want to move as soon as possible," said Luis. "And I'm7 of looking at houses we can't afford," Gloria added. So they8 to buy the old house and repair it. The house will need a lot of work, but it's in a nice 9 and the back yard is big. It'll look10 after it is repaired.

When I was in primary school, I got into a big argument with a boy in my class. I forgot what the argument was about, but I will never forget the lesson I learned that day.

I thought that I was right and he was wrong and he thought that I was wrong and he was right. The teacher decided to teach us a lesson.

She brought us to the front of the class and asked him to stand on one side of her desk and me on the other. In the middle of her desk was a large round ball. I could clearly see that it was black. She asked the boy what color the ball was. "White," he answered.

I couldn't believe he said the ball was white, when it was obviously black!

Another argument started between us, this time about the color of the ball.

The teacher told us to change places and then asked me what color the ball was. I had to answer "White". It was a ball with two differently colored sides, and from his side it was white.

From my side it was black.

Sometimes we need to look at problems from the other person's view in order to truly understand his or her ideas.

Being safe in your everyday life needs knowledge. If you remember the following information, your life will be much safer.

Always notice the environment around you. You shouldn't walk alone outside. Make sure where the public phones are. If anything dangerous happens, you can find them easily.

Your bag should be carried towards the front of your body instead of putting it on your back. When a bus is full of people, it is easy enough for a thief to take away the things in the bag on your back．

If you are followed by someone whom you don't know, cross the street and go to the other way, let the person understand that you know he or she is after you. Next, don't go home at once. You are safer in the street than you are alone in your home or in a lift.

If you have to take a bus to a place far away, try to get to the stop a few minutes earlier before the bus leaves. This stops other people from studying you. On the bus, don't sit alone. Sit behind the driver or with other people. Don't sleep.

"Why do I live? Why do I wish for anything, or do anything? Is there anything in my life that will not be destroyed by my death?" Like Leo Tolstoy, the famous Russian writer, many people ask these difficult questions. Tolstoy spent his whole life trying to answer these difficult questions.

As a young man, he thought people could achieve perfection if they tried hard enough. So he worked very hard to be the best in everything. He thought that he would find meaning and truth in success.

In the 1850s, Tolstoy wrote his first stories. He wrote about his life in the army. He also told stories about his childhood. These works were published and Tolstoy became a well-known writer.

He earned the respect he always wanted. Many rich and smart men met and talked with Tolstoy. Some of them were writers like him. They talked a lot about faith (信仰) and the meaning of life. But soon Tolstoy recognized that these men were not perfect. Now he knew they could not answer his questions about faith.

So in the 1860s, Tolstoy tried a different way to find the meaning of life. He opened a school for the children of his serfs-the people who worked on his land. These workers were very poor. He wanted to help them because he thought they were more honest than the rich people he knew.

Tolstoy learned a lot from his workers. He understood how they worked hard to support their families. He began to believe that marriage and family would give his life meaning. So in 1862, Leo Tolstoy married a young woman named Sonya Behrs.

The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books-War and Peace and Anna Karenina. Many experts say that War and Peace is one of the greatest books ever written. In these books, Tolstoy believed humans should live a simple life and take care of their families. Tolstoy thought this would satisfy him and bring him happiness.

Leo Tolstoy is still a very respected writer today. His faith and writings have influenced many people all over the world.

Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution.

To improve the environment, many countries are developing electric vehicles (EVs, 电动车). Among them, China is taking a leading role and has created the world's largest EV market.

Last year, over 40 percent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.

"Filling up a fossil fuel car with gas (汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric car this year.

However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before needing to be recharged.

Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 167, 000 charging piles in total.

Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

"As China goes, so will the world's car industry," The Wall Street Journal said. China has taken a leading role in the world's electric vehicle industry.
