Americans love to cheer for their favorite football teams.

Join in football fun

The National Football League(NFL) is exciting for many Americans. If you live in the US and don’t understand the sport, you can easily feel left out. Here are some tips to help you go from outsider to super fan.

Learn the basic rules

There are two teams, each with 11 players on the field. The team on offense（进攻） aims to run with the ball to the opposing team’s end zone for a touchdown or kick the ball through the other team’s goalposts for a field goal. The team on defense (防守) aims to stop these things from happening or take control of the ball for themselves. The team with the most points at the end wins.

Get into the drama

It’s exciting to see powerful players moving the ball forward on offense- and equally powerful defensive players trying to stop them from getting points. The game sometimes causes serious damage to players’ brains. “As long as no one gets terribly hurt, the hitting is the best part,” said Calvin White, a 16-year-old from New York.

Watch the Super Bowl

The Super Bowl is the annual championship game of the NFL. Nearly 110 million viewers will watch this game on TV. Even non-fans don’t want to miss the star-studded halftime show. It’s not only a treat for US football fans, but also a global wonder.

What things do football players have to wear?

American football is a violent sport. Players tackle each other to get the ball. Although the conflict is exciting, players must have gear（装备）to protect themselves from serious injuries. Here is some of the gear they wear.

I didn’t want to be a bodybuilding champion. I wanted to be the best bodybuilder of all time.

Deep, deep down ask yourself, “Who do you want to be?” Not what, but who. I’m talking about thinking it out for yourself, “What makes you happy?”

You have to think outside the box. That’s what I believe, after all. What’s the point of being on this Earth if all you want to be is to be liked and avoid trouble?

We have so many rules in life about everything. I say break the rules. Don’t break the law, but break the rules.

I remember that after I had finished with my bodybuilding career I wanted to act. I wanted to be a star in films. Everyone had the same thought that I couldn’t be done. They said, “Look at this body, you have this huge monstrous body, you’re overly developed.” They thought I wouldn’t fit into movies. But I didn’t listen to them. Those were their rules. I was completely certain that I could do it.

Then I got my big chance in Conan the Barbarian. That shows you should trust yourself no matter what anyone else thinks.

On that movie, the director said, “If we didn’t have Schwarzenegger, we would have to build one.” Then when I did The Terminator, I said, “I’ll be back…” One of the famous lines in movie history, all because of my crazy voice. It just shows that you should never listen to those who say you can’t do something.

Don’t be afraid to fail. In everything that I have tried, I’ve always been willing to fail. Don’t be afraid of making decisions. You can’t be frightened with the fear of failure or you will never push yourself. You can push because you believe in yourself and your imagination. You know it’s the right thing to do and success will come. Don’t be afraid to fail.

---By Arnold Schwarzenegger

Since the COVID-19 outbreak, many people have been forced to stay at home for long periods of time to protect themselves from the virus. This has given people more free time to learn new skills and find different ways to entertain themselves.

Some of these activities include things like singing, learning to cook and ordering fresh food online. All of these things can be done in the palm of your hand with mobile apps.

Before, young people would go outside and meet friends at karaoke bars. Now, friends can meet and sing on the mobile karaoke app Changba, which translates to Singing Bar. “The Changba app not only gives me the chance to sing whatever I like at home, but also lets me keep in touch with friends by sharing our songs,” said an app user.

Some people have also taken up cooking as a new hobby to pass the time. You don’t need to attend culinary(烹饪的) school, thanks to apps like Xiachufang and Ecook, which make it easier for those who want to learn how to cook. These apps provide a platform for users to look up different recipes (菜谱) and to share their own recipes with others. “Using this app, I have learned many new and healthy dishes which help me eat better,” an app user commented on the app’s website.

To help people avoid crowded places like grocery stores, apps that deliver goods right to your door have also become very popular. “It is noteworthy that the epidemic has attracted new groups of consumers(消费者), such as elderly people, who originally didn’t belong to our target user group,” Zhang Yi, an analyst (分析师) from the market research company iiMedia Research, said.

Indeed, during this special time, these apps have opened up a whole new world of opportunities for people of all ages and backgrounds.

If you are a recent social science graduate who has had to listen to jokes about unemployment（失业） from your computer major(专业课) classmates, you may have had the last laugh. There are many advantages for the social science major because this high-tech “Information Age” requires people who are flexible(灵活的) and who have good communication skills.

There are many social science majors in large companies who fill important positions.

For example, a number of research studies found that social science majors had achieved greater managerial（管理的） success than those who had technical training or pre-professional courses. Studies show that social science majors are most suitable for change, which is the leading feature(特点) of the kind of high-speed, high-pressure, high-tech world we now live in.

Social science majors are not only experiencing success in their long-term company jobs,but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry-level (入门的) positions with social science graduates. The study also showed that the most important quality in a person who was looking for a job was communication skills, noted as “very important”, by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably because of these skills that they have been offered different kinds of positions.

Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don’t regret their choice of study.

Everyone speaks a language, but language is not just for talking. It is our most important communication tool. Through language, we can tell other people what we think, how we feel, and what we need. In fact, civilization (文明) itself depends on our ability to communicate.

In the long history of human, languages survive, grow, disappear, move from place to place, and change with time. There are about 6,000 different living languages around the world today, and there are many thousands more that are no longer in use. Languages might sound different, but they are thought to have come from a single ancient language.

Nobody knows exactly when people first started using languages. Some scientists say that people first spoke to one another about two million years ago.

Today, our complicated (复杂的) languages get fully used in the magazines, novels, science books, and movies that fill our libraries and bookstores. As humans, it is important that we can tell the long stories, which separates us from the great apes (类人猿). Other animals may use kinds of methods to communicate, but we humans can send complicated messages through space and time.

Throughout history there were many languages that served as a lingua franca (通用语)—a common language that could serve as a bridge between people of different cultures. Today, English is the main language that plays that role around the world. Many people have studied English as a second or third language.

Language helps people to work together, to share knowledge, feelings, and build up modern societies. The development of humanity’s many languages was an important process that helped humans move forwards towards civilization.
