【推荐1】It was a cold winter night when the police officer Lee and the detective Smith were walking back to the police station. They saw a robber attacking an old woman on the road. Lee and Smith ran over to the robber at once.

The robber saw them and ran away as fast as he could. Lee and Smith followed him for a long distance until the robber rushed into an underground station. Lee and Smith ran into the station and tried to find him. It was quite dark outside that night and they couldn’t see the robber clearly. But they remembered what his body shape was like.

When they went in, they saw six men in the station. All of them had the similar build as the robber. Lee looked at them carefully, one by one.

The first man was arguing(争辩) with an underground station worker. He seemed to be very upset.

The second one was watching the fight between the first man and the worker. It seemed like he was quite interested in it.

The third one was running to warm himself up, as it was cold in the station.

The fourth one was quietly reading a newspaper. His face was hidden behind the newspaper.

The fifth one was wearing a big coat, sitting on a bench quietly.

The sixth one was waiting for the underground. He looked at his watch several times. He seemed to be in a hurry.

Lee finally found out which one the robber was. He whispered to Smith, “Look! The robber wanted to cover up his panting(气喘吁吁) by doing this.”

【推荐2】A 12-year-old girl from Virginia, US, never thought that a simple message she put online could bring her big problems. She posted the words,"Killing. Meet me in the library Tuesday”,   with three emojis（表情符号）of a gun, a knife and a bomb (炸 弹 )on Instagram, a social media (社 交媒体). She was told that she broke the law because of threatening （威胁）her school.

This problem is not far away from us. Not long ago, Ni Hanxiang, a Chinese student at university in the US, was sent back to China after expressing on social media that he would kill his teachers if he failed to pass his exams.

In China, posting threatening words online is also against the law. In 2013, Wu Hongfei, a singer, got into trouble for saying on weibo that she wanted to blow up a building.

"Threatening happens not only face to face but also through the Internet, social media and the telephone,” said Mr.Cao, a lawyer from Chongqing."Although the law of China protects people's right of free speech, it doesn't include words that threaten others' lives and national safety."

"Some people may not mean to threaten. They may just be trying to say 'I'm strong’,” said Fred Pratt, a lawyer from the US.

The girl's mother said her daughter was a good kid who had never been in trouble before. Ni Hanxiang also said he didn't realize that what he put online was so serious.

"But not knowing the law doesn't mean the law will treat you any differently if you break it,” says David Allen Green, a lawyer from the UK. So, do you think we'd better spend a minute or two thinking about the words or emojis we use on social media before we press "send"?

【推荐1】The Nile River is the longest river in the world. It’s called “Father of African Rivers”. The Nile River was important to survival (生存) in ancient Egypt.

Egyptian people depended heavily on the river for drinking and bathing. The Nile was also an important transportation route (路线). Traders traveled along the river. They transported objects to other areas. Fishermen used the Nile to catch fish for food. Workers moved stones and other things for making pyramids (金字塔).

The ancient Egyptians created inventive ways of using the river. One important invention, still used today, is the “shaduf”. This was designed to get water from the river and move it so the water could be used on land to help the crops grow.

In ancient Egypt, the Nile River flooding wasn’t considered a natural disaster (灾难). Not only did the flooding help water crops, but it also deposited (沉淀) rich soil along the banks of the Nile. The soil was used to grow crops to feed the ancient Egyptians. The flooding of the Nile also helped ancient Egyptians survive by providing shelter. When the Nile flooded, it left behind rich soil, as well as mud. The ancient Egyptians used this mud to build mud-brick houses.

Apart from the river, Egyptians also depended on the “red land”. This was the red desert where nothing grew. It protected the people of ancient Egypt by separating the country from neighboring countries and invading (入侵) armies. The “red land’’ was rich in valuable metals and gems (宝石).

【推荐2】On the fourth Sunday of every November, most Americans get together around the dinner table to celebrate Thanksgiving. Special traditions in the US have been around for many years.    1    These are four popular Thanksgiving traditions and how they started.

    2    The first Thanksgiving meal was in the autumn of 1621 when the first travelers from England celebrated their first harvest(收获). But it wasn't made into an official(官方的)holiday until 1863. The first large meal had turkey, fruits and vegetables, which are still common today.

    3    Historians say the first travelers invited Native Americans to the meal to thank them for teaching them how to grow food. Today at the large meal, friends and family will also say what they are most thankful for.

    4    The parade includes very large balloons that look like cartoon characters and beautiful floats that carry famous people. There are also many musical performances to watch. This parade started in 1924, and today over 44 million people watch it on TV or in New York City.

    5    People started to watch football on Thanksgiving a few years after the day became an official holiday. Today, the National Football League takes advantage of this popularity and hosts three NFL games every Thanksgiving.

【推荐3】Most American families are small. Most American families each have one child or two children.

Children in the USA will leave their parents’ home when they grow up. They usually live far from their parents because they want to find good Jobs. They often write to their parents or telephone them. And they often go to visit their parents on holidays.

Parents in the USA usually let their children choose their own jobs. Americans think it’s important for young people to decide on their lives by themselves. Children are asked to do some work around their houses. And in many families, children are paid for doing the housework so that they can learn how to make money by themselves.

【推荐1】Did you know that when you surf the Web, many websites (网站) put secret software on your computer? The software collects a large amount of information about you and sends it to Internet companies. The Internet companies sell it to other businesses. Your personal information can also be collected from social media sites. There are many ways your information can be used.

What information do they collect and why? The companies find out where you live, what websites you visit, and what you do online. With this information, they can guess other things about you. For example, they can guess if you are male or female, how old you are, and your interests. The companies use this information to decide which advertisements are best for you.

What do they do with your information? Your personal information could also be sold. Some companies collect information just because they can sell it to other businesses. A business that collects and sells personal information is called a data broker (数据代理商). When data brokers sell your information, a lot of different companies will know your online habits. Then these companies will advertise products or other websites to you.

What online habits are tracked (追踪)? Another way your personal information can be collected is through social media. When your information is on social media, a lot of people can see it. Even if you don’t use social media, a friend might post a picture or video of you with your name on it. If someone knows too much about you, they can steal your identity (身份). Then they can buy things online and post messages while pretending (装作) to be you.

All of your online habits can be recorded. Studying people’s online habits is big business. Your personal information is very valuable to companies. That is how they know who to send their advertisements to. The Internet reaches almost every corner of the world, but the danger is that your personal information might travel that far, too.

【推荐3】Each nation has many good people who help to take care of others. For example, some high school and college students in the United States often spend many hours as volunteers in hospitals, orphanages (孤儿院) or homes for the old. They read books to the people in these places, or they just visit them and play games with them or listen to their problems.

Other young volunteers go and work in the homes of people who are sick or old. They paint, clean up, or repair their houses, do their shopping or mow their lawns. For boys who no longer have fathers there is an organization called Big Brothers. College students and other men take these boys to baseball games or on fishing trips and help them to get to know things that boys usually learn from their fathers.

Each city has a number of clubs where boys and girls can go to play games or learn crafts. Some of these clubs show movies or organize short trips to the mountains, the beaches,museums or other places of interest. Most of these clubs use a lot of high school and college students as volunteers because they are young enough to remember the problems of younger boys and girls.

Volunteers believe that some of the happiest people in the world are those who help to bring happiness to others.
