I returned home the other night, tired. My husband asked me how my evening was, “Great.” I told him. I had spent 90 minutes in a gym with 10 Ping-Pong tables and all kinds of players, all playing a little ball over the net. By 9 pm, I was excited, tired, satisfied. I had beaten two young men half my age and lost battles against other competitors. To an observer, the night was common. To me, it was a lucky thing that I hadn't expected.

    I had taken up Ping-Pong during college, and in my 30s took more advanced lessons. However, a serious accident hurt my leg, which made me unable to take exercise. Months later, I tried to play Ping-Pong but my leg pained for a week. I put the game out of my mind.

When I was 53, one day my bad leg was working a little bit better. Could Ping-Pong be possible for me, now—in my condition, at my age? I tried to play Ping-Pong again

    Ping-Pong is a sport which requires endurance(耐力). Players need quick foot work and upper body movements to return balls, requiring faster response time than tennis.

    Playing Ping-Pong offers benefits for the brain. A study of 164 women aged 60 and older showed that Ping-Pong improved cognitive(认知)function more than dancing, walking or gymnastics. “The great thing about our sport is that it can be played by anyone,” said Jimmy Butler, a four-time national USA Table Tennis Association winner. “I see 90-year-olds and 10-year-olds.”

    Years passed and my endurance improved. People started to praise my shots. I won a game. Then I won agin. These days, I feel wonderful, I believe this sport is the fountain (源泉)of youth.

    What is it that makes people laugh? More than two thousand years ago the ancient Greek philosopher Aristotle defined (定义) jokes as the pleasure that results from a feeling of triumph(胜利) by showing we're better than someone else in a certain way. According to Aristotle and many other philosophers，all jokes depend mainly on showing inferiority in another person or group of persons—that is，putting it clearly，on showing that they are worse off than ourselves. Jokes raise our good opinion of ourselves at someone else's expense.

Showing how much better than other people we are is only one reason we like jokes. Someone may also use a joke to express their anger or their cruelty or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a banana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes，especially those involving cruelty，are so popular with certain people.

    Besides，all jokes depend on our enjoyment of laughing at something that is strange and out of place because it's different from things which are happening around it. The same situation can be either sad or pleasant，depending entirely on how strange and out of place it is. If a girl in a bathing suit falls into a swimming pool，we don't laugh because nothing unusual has happened. But if a man in a smart suit falls in，the situation is at once unusual in a pleasant way and we laugh. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens，and so we laugh.

Around the World by Wheelchair

    Rick Hansen was always an active kid and loved to fish. When returning in a truck one day from a fishing trip, he had an accident and suffered injuries to his spine (脊柱)，This 15-year-old young man awoke to find that he had lost the use of his legs. However, he didn't give up. Many months later he began to compete in wheelchair sports. At the age of 27, he decided to wheel around the world to raise awareness and money for spinal cord research. His tour took him through 34 countries around the world between 1985 and1987. In this Man of Motion World Tour, he wheeled 24,901.55 miles, which is equal to the distance around the earth.

    Bad weather and difficult, rocky roads often provided challenges for Rick, but he continued to push himself to complete the trip. He was determined to succeed. Even mountains did not stop Rick Hansen. He wheeled himself up the Rocky Mountains and several other major mountains in the world. He even wheeled himself along the Great Wall of China!

    “Never Give Up On Your Dream” was his motto and he hasn't given up yet. He completed his world tour raising $24 million. He continues to work to increase knowledge of spinal cord injury. He is a true Canadian hero who shows what determination can achieve.

    For many foreigners who have visited or worked in China, one of their strong impressions is that the country is very safe. Here , you can go out alone late at night to eat at a food stand without feeling nervous. You can also let your younger children ride public transport all by themselves without worrying about their safety.

    This year, 2018 , marks 8 special anniversary of the launching of the reform and opening up policy, which took place two score years ago in China. Over the past few decades, the country has achieved fast economic growth, while social peace and stability have been maintained(维护) to the fullest extent at the lowest cost. Of course, there are still unsolved problems. However, from the overall aspect, Chinese society remains harmonious and safe. In my eyes , this should be attributed(归于) largely to the cultural ;economic and political environment of the country.

    A society can be stable and orderly only when its people can lead a prosperous(繁荣的) life. After the introduction of the reform and opening up policy, China achieved fast economic growth and significant scientific and technological progress. In the meantime, the Chinese government has taken various measures such 2s those to fight corruption, reduce poverty and promote the rule of law, in order to uphold social equity. Thanks to these efforts, the potential factors that might cause social problems have been greatly reduced.

    Apart from government departments including the police and judicial(司法的) departments , the general public also contributes much to social governance. The development of information technology has created new ways of linking the police and the public. By jointly fighting crimes in such ways, the public and the police have developed an ever-increasing level of mutual trust and positive interaction.

    The safety and stability in China did not come easily. Rather; it should be attributed to the efforts made by 1.3 'billion people. For both Chinese and foreigners living in the country, the sense of safety and security is very precious.

    If you go into the forest with friends, stay with them. If you don't, you may get lost. If you get lost, this is what you should do. Sit down and stay where you are. Don't try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle(吹口哨) three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.

    Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.

    If you don't think that you will get help before night comes, try to make a little house with branches(树枝). Make yourself a bed with leaves and grass.

    When you need some water, you have to leave your little branch house to look for it. Don't just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place.

    Last week, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon.

    Imagine never having to worry about traffic, stop lights, or road construction. A flying car would get to a place much faster than one travelling by road. On the other hand, imagine having to avoid drones (无人驾驶飞机) and other flying cars. Also, what if your battery dies when you are in the air? And, how will you know where to land?

    Kitty Hawk is a start-up tech company supported by Google co-founder, Larry Page. According to the Kitty Hawk website, its car will be able to travel at speeds up to 40 kilometers an hour in the air. It says under US aviation law such a machine “does not require registration or a pilot's license and may be flown in uncongested (不拥挤的) areas for recreational purposes.” As of now, the car can only be flown over fresh water.

    Kitty Hawk is making a list of people interested in buying the flying car. They must pay a deposit of US$100. Those who get their names on the list early will receive US$2, 000 off the final cost of the car. However, Kitty Hawk has not yet announced the price. Kitty Hawk expects its first flying cars will go on sale by the end of this year.

    At a conference last week, Uber announced plans for flying taxis to begin carrying passengers. Unlike the Kitty Hawk company, Uber does not plan to build its flying cars. Instead, it will use the resources of partner companies.

    Like the Kitty Hawk car, Uber flying taxis will use electric power. Uber says its flying taxis could travel up to 241 kilometers an hour. The company said that could reduce the travel time between San Francisco and San Jose, California from two hours on the road to 15 minutes in the air.

    Riders could use the Uber app to book a flying taxi to take them to their destinations. The company has not yet said how costly air taxi travel would be compared to road taxi travel.
