China covers large areas and has a great population. Different living habits have always been an interesting topic in the country. Recently, another difference between southern Chinese and northern Chinese became a hot one: the way people shop at markets.

    People from southern China say that they always buy what they need for just one or two meals. It is normal for them to buy half of a Chinese cabbage, two potatoes and 0.25 kilogram of beef at a time.

    However, one may be laughed at if he does this in the north. Instead, buying vegetables and meat enough for a week is usual. Also, you can buy a small amount (数量) of fruit, such as a single apple or pear, each time in the south. Shop owners even help you peel and cut them. But shop owners in the north hardly offer such service. And many fruits are sold in baskets and boxes.

    The difference could be due to the different weather.

    Food can be kept for a long time in the north, as it is usually cold and dry there. Many northern Chinese have the habit of storing food, especially for the long winter. But the hot and wet weather in the south makes southern Chinese buy just enough food for one meal or one day, or else the food may go bad.

    My name is Sam. I joined a club called" passing help" last month: Now let me tell you why I joined it.

    One evening this May, on my way home my-old car broken down. It was 25 miles from my home.

    I wanted to get a ride, but there was no car. It was also hard to take a taxi. I decided to take a bus home. I went to bus stop nearby.

    After a while, a bus came, but it did not go to my town. The bus driver was a young woman.

    She was kind and she told me which bus I should take. I waited there for about thirty minutes, but no bus came. At last a car came to me and a woman came out of the car. She was just the bus driver.

    "When I reached the bus station, I got to know that the bus to your town couldn't come, so I returned here. I just can't leave you here," she said, "Get in my car and I will take you back to your home," "It is a long way." I said." Come on, sir," she said," Let's go."

    On the way she told me a story. A few days ago, there wasn't .gas(汽油) in her car. An old man drove her up to a gas station and then back to her car.

    When we got to my home, I wanted to give her some money to thank her, but she didn't accept. "I only want to help others and do something nice for somebody. Pass it along. "She said.

    Being street smart is an important skill to have and a good way to take care of yourself.

    Always carry your phone with you, but do not look at 1 while you are walking. Being able to communicate or call for help is important, so keep a list of useful numbers. But put your phone away while you are walking so that you can keep your 2 up and see what's going on around. If you do need to check your phone, 3 and look at it quickly.

    Don't wear earphones 4 you are out. If you have to 5 something when you're out, use only one earphone or play it at a very low volume(音量).

    Travel with 6 or family members when possible and never go anywhere with a stranger. It's 7 to be careful with strangers. Remember not to get into a stranger's car if they call you over.

   8 dark and out-of-the-way places. Do not take short cuts through dark areas, even if it will make your trip much faster. If you have to go to unsafe places, go 9 someone you know or speak to someone over the phone while you are there.

    Run and shout if you feel unsafe. Run away as fast as you can towards a police station, hospital, or nearby business for 10. Shout as loudly as you can to get the attention of people nearby.

You can see many dfferent monsters (怪兽) in the movie Hotel Transylvania 3: Summer Vacation. Some of them have a holiday on a big ship.

Rock climbing（攀岩） did not become a sport until late in the 1900s. But now it has become a popular outdoor activity. While rock climbing may still be necessary for mountain climbing，most people just climb low mountains for fun. 

If you have ever done rock climbing，you will know that it is not a very easy sport. Indoor and outdoor rock climbing both need practice. What most people don't know is that rock climbing is one of the sports that depend on your body and mind（意志）. 

To climb successfully，one must use wonderful skills. One of the important rules is to always have three parts of your body on the rock face. Another important rule is that your arms only hold you close to the rock face while your legs are pushing you up，the closer you are to the rock face，the easier it is to climb. 

Rock climbing is a wonderful sport. Once you start to learn how to climb，you'll find more fun. People who like games such as chess playing or problem—solving may love rock climbing，because they are nearly the same in the way of thinking. For anyone who wants to get into beautiful shape，rock climbing is a fun and good way. Anyone who enjoys a difficult game and loves the outdoors should think of taking rock climbing as a new hobby.
