"Bill, you never miss！"Joe said admiringly. "Unless I'm in a real game, "Bill complained. "Then I miss all the time. " Joe knew that Bill was right. Bill performed much better when he was having fun with Joe in the schoolyard than he did when he was playing for the school team in front of a large crowd. " Maybe you just need to practice more, "Joe suggested. "But I practice all the time with you！"Bill said. He shook his head. " I just can't play well when people are watching me. " "You play well when I'm watching, " Joe pointed out. "That's because I've known you since we were five years old, "Bill said with a smile. " I'm just not comfortable playing when other people are around. " Joe nodded and understood, but he also had an idea.

The next day Joe and Bill met in the schoolyard again to practice. After a few minutes, Joe excused himself. " Practice without me, "Joe said to his friend. "I'll be back in a minute. "

Joe hurried through the school building, gathering together whomever he could find-two students, a math teacher, two secretaries, and a coach. When Joe explained why he needed them, everyone was happy to help. Joe reminded（提醒）the group to stay quiet as they all went toward the school's basketball court. As Joe had hoped, Bill was still practicing basketball. He made five baskets in a row without noticing the silent people standing behind him.

"Hey, Bill" Joe called out finally. Bill turned. A look of surprise came over his face. "I just wanted to show you that you could play well with people watching you," Joe said. "Now you'll have nothing to worry about for the next game!"

   When it comes to exercise，most of us fit into one of the two groups — those who keep a regular exercise habit and those who think about being more active but can’t seem to have a plan to do it consistently. Whatever your attitude to exercise，there’s another form of physical activity that many of us car-loving people can do to get enough movement in general.

Studies have shown that putting away your car and walking, biking or taking public transport to work can have a significant positive influence on your health by improving spirits, reducing body weight and lowering the risk of heart disease.

It’s not surprising that taking a bus or a train regularly leads to a more physically active lifestyle. Just think about what comes with using public transport. Those who travel to work without a car walk to stations, climb stairs, often stand while waiting for their bus or train, and then finally travel on foot or by bicycle to their destination. Such active transport can make up for the inactive time spent in work and school environments.

There’s no doubt that the improving public transport system in the city is influencing the way people work and live. But though the public transport system is improving, it is not within easy reach of everyone who would like to use it.

Bike-sharing programs are also growing in popularity（普及）and helping to bridge a gap in the crowded city public transport system. These programs allow users to easily book, ride and return a borrowed bike. Bike-sharing programs help people who might still need to travel some distance between the end of the bus or the underground line and their final destination. They also offer an opportunity to residents and visitors to travel freely around the city without being trapped in a car.

   Of all my dreams, my least favorite is the one where I'm in a car. It always begins with me driving, but eventually I realize that for some reason I'm sitting in the back seat. I can’t keep the car under control, rushing toward the roadside until, screaming, I wake up.

This is like the passenger experience in Waymo's self-driving cars. You sit in the back seat of a vehicle and watch as the wheel turns itself above an entirely empty driving seat.

''We made you live your nightmare, '' a Waymo staff member joked after I exited one of the company's fully self-driving car, following a quick drive inside its secret testing site. Waymo, a self-driving car company, arranged these rides for 40 journalists at this site.

There were also some demonstrations(演示). We watched as a Waymo car was cut off by a speeding vehicle. Then the employees created a situation in which a pile of moving boxes fell into the street just as another car passed in the opposite direction. Throughout the day, the cars performed impressively, driving with the level of care you might take if you had a wedding cake in the back seat.

During these demonstrations, Waymo gave information about what it was planning to do with these vehicles. The company has laid out four ways that its technology could be made available to the public. But Waymo's CEO, John Krafcik, wouldn’t show which of these was likely to come to market first, or on what kind of timeline.

I can't help but admire that Waymo is succeeding in developing this technology. There are countless possibilities at play on the road. The task of programming software to react to all those situations is unimaginably complex. What a great breakthrough!

During the summer vacation this year, I thought I should do anything meaningful instead of stay at home, so I got a job at a KFC fast-food restaurant, working there as a cleaner. I worked seven hours a day for three week. The job was hard and boring, which made me very tired that I nearly gave it up halfway. And I went on with determination. Every day I started off for work early in the morning and reached to home late in the evening. Final I finished the job before the new term begins. Now, I understand that work means. I think it is really successful experience.

   Kids' health：Four steps for fighting stress

Everybody gets stressed from time to time. 【小题1】 Some ways of dealing with stress — like screaming or hitting someone — don't solve (解决) much. But other ways, like talking to someone you trust, can lead you to solving your problem or at least feeling better.

Try taking these four steps the next time you are stressed：

(1)Get support. When you need help, reach out to the people who care about you. Talk to a trusted adult，such as a parent or other relatives. 【小题2】 They might have had similar problems，such as dealing with a test, or the death of a beloved pet.

(2)Don't take it out on yourself. Sometimes when kids are stressed and upset they take it out on themselves. Oh, dear，that's not a good idea. Remember that there are always people to help you. Don't take it out on yourself. 【小题3】

(3)Try to solve the problem. After you're calm and you have support from adults and friends，it's time to get down to business. 【小题4】 Even if you can't solve all of it，you can solve a piece of it.

(4)Be positive. Most stress is temporary (暂时的). Remember stress does go away, especially when you figure out the problem and start working on solving it.

These steps aren't magic，but they do work. And if you can stay positive as you make your way through a tough time，you'll help yourself feel better even faster. 【小题5】
