That cold January night,I was growing sick of my life in San Francisco.There I was,walking home at one in the morning after a tiring practice at the theatre.With the opening night only a week away,I was still learning my lines.I was having trouble dealing with my part-time job at the bank and my acting at night at the same time.As I walked,I thought seriously about giving up both acting and San Francisco.City life had become too much for me.

    As I walked down empty streets under tall buildings,I felt very small and cold.I began running,both to keep warm and to keep away from any possible robbers.Very few people were still out except a few sad-looking homeless people under blankets.

    About a block from my apartment,I heard a sound behind me.I turned quickly,half expecting to see someone with a knife or a gun.The street was empty.All I saw was a shining streetlight.Still,the noise had made me nervous,so I started to run faster.Not until I reached my apartment building and unlocked the door did I realize what the noise had been.It had been my wallet falling to the sidewalk.

    Suddenly I wasn't cold or tired anymore.I ran out of the door and back to where I'd heard the noise.Although I searched the sidewalk anxiously for fifteen minutes,my wallet was nowhere to be found.

    Just as I was about to give up the search,I heard the garbage truck pull up to the sidewalk next to me.When a voice called from the inside,"Alisa Camacho"I thought I was dreaming.How could this man know my name?The door opened,and out jumped a small red-haired man with an amused look in his eye."Is this what you're looking for" he asked,holding up a small square shape.

    It was nearly 3 a.m. by the time I got into bed.I wouldn't get much sleep that night,but I had gotten my wallet back.I also had gotten back some enjoyment of city life.I realized that the city couldn't be a bad place as long as people were willing to help each other.

Editor: Today our topic is part-time job. Are they good for school children or not?

Headmaster: Certainly not. Children have got two full-time jobs already: growing up and going to school. Part-time jobs make them so tired that they fall asleep in class.

Mrs. White: I agree. I know school hours are short, but there's homework as well, and children need a lot of sleep.

Mr. White: Young children, perhaps some boys, stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They earn their pocket money instead of asking their parents for it. And they see something of the world outside school.

Businessman: You're quite right. Boys learn a lot from a part-time job. And we mustn't forget that some families need the extra money. If the pupils didn't take part-time jobs, they couldn't stay at school.

Editor: Well, we have got two for, and two against. What do our readers think?

    The 90-minute documentary, Amazing China, which is co-produced by China Central Television and China Film Corp, opened in theaters nationwide on Friday.

    The film focuses on the major achievements the country has made since the 18th National Congress of the Communist Party of China in 2012 under Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era（时代）.

    The documentary focuses on key Chinese infrastructure（基础设施）projects in aerospace, high-speed rail, the Hong Kong-Zhuhai-Macao Bridge and the world's largest single-dish telescope FAST.

    The documentary also informs viewers that seven of the world's 10 biggest sea ports are now in China. And that the country now has the longest high-speed rail network in the world.

    Speaking of the significance of the new documentary for the Chinese, La Peikang, the head of China Film Corp, says: “It's not only about showing the achievements, but presenting the status quo of China.

    “The film will help people to know our country better. The moving stories behind the Chinese miracles reflect the people's endeavors and spirit.”

A good documentary is usually a vivid portrayal（描绘）of individual stories rather than slogans, and Amazing China is no exception.

    One of the most touching moments in the film is probably footage from an interview of Nan Rendong, often called the “father of FAST”.

    Amazing China also focuses on common people.

    In the film, you see a young Tibetan woman volunteering in rural areas to help people poverty.

    The movie shows that their work is not easy, but their spirit and unwavering belief make it possible to achieve their targets. And, they are just representative of the many Chinese who work as hard.

    China is the world's second-largest economy. But the country still faces “the contradiction between unbalanced and inadequate development and the people's ever-growing needs for a better life”, as stated in the CPC's 19th National Congress in November. However, as this cinematic production proves, the documentary is a good way for country to boost self-confidence and to aspire for a brighter future.

    Can you imagine walking into a gym and seeing dogs lifting weights or cats jogging? We're being a bit silly thinking of dogs and cats going to the gym, but we do have a reason. Just like human beings, pets that don't get enough exercise can become overweight.   
   Overweight pets can develop serious health problems just like we can. So, if you have a pet, part of being a good owner is making sure that your pet gets the right amount and kind of exercise.

    Before you start your pet on an exercise program, be sure to schedule a check-up for your pet and ask your veterinarian how much and what type of exercise your pet needs.

    Just like humans, pets need to be started out slowly. Over time, they will get fit and be able to exercise for longer periods of time. If you exercise alongside your pet, you'll benefit, too!

    Starting out, you might want to play with your pet for 15－20 minutes at a time. Gradually, you can turn those plays into several 30－minute walks or jogs each week. If your pet is especially active, you can extend them to an hour or longer.

    Of course, some pets, such as cats, may not be easy to take for a walk or a run. These pets still need exercise, though. Don't underestimate the value of energetic indoor play, such as games of chase, for these types of pets.

    As you start exercising with your pet, here are some things to keep in mind:

    Make sure your pet has plenty of water before, during, and after exercising.

    If you have older pets, don't push them as hard.

    Watch the heat! If you are outside, exercising with your pet will be best early in the morning or later in the day.

    China is a country of many resources. Among its resources are many great rivers, which provide useful transport routes. Water transport is an efficient way to carry heavy loads, such as grain. In ancient times, a waterway was needed between China's rich farmlands and the capital city. This need inspired engineers to build a canal. According to writings by the ancient thinker Confucius, work on a canal linking the Yangtze River with the city of Huai-in began about 486 B.C. For many centuries afterward, Chinese emperors worked on extending this ancient canal.

    This canal is now known as China's Grand Canal. One thousand years after the original canal was begun, it was in extreme need of repair. This was in the year 607, during the Sui Dynasty. By 610 the emperor had had the canal extended. The Grand Canal formed a northeast-southwest link between the Yellow River in the north and the Huai River in the south. The canal remained the main waterway in this part of China for the next five hundred years.

    In the thirteenth century, the Mongols had conquered China. The Yuan Dynasty established Beijing as the capital. The city's growing population needed food, so a new canal was built to extend shipping. Building this part of the Grand Canal required enormous effort and cost. Neither the first attempt nor the second one was successful, so the builders chose another route. Finally this link in the Grand Canal was finished.

    By the time of the Ming Dynasty, the Grand Canal had six sections. These were busy with goods until the nineteenth century. Then a series of severe floods struck China. Parts of the Grand Canal were badly damaged. By 1868 it had been largely abandoned as a means of northern route.

    The Grand Canal was mostly restored in the twentieth century. It was widened and deepened, and a new section was constructed. Today the canal, which is about 1,200 miles in length, has new locks(运河的水闸). It is busy with ships and barges(驳船) carrying goods to and from cities along its banks.
