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.

Here is a part from Maria'sdiaries(日记) about her vacation.

The 3^rd Day:Yesterday we arrived in London in the rain. We went to some big shops.

The 4^th Day: Wecame to Paris. The day was cloudy and the food wasn't good. We liked the shopshere, but the things were dear.

The 5^th Day: Wearrived in Rome in the hot weather. We had lunch in a small restaurant, and thefood was delicious. We visited some shops. They were all wonderful.

The 6^th Day: Wewent to New York and the things in the shops were all dear. But we liked thewarm weather there.

The 7^th Day: Todaywe visited New York City. The weather was fine. We'll go back home tomorrowafter a week's vacation.

In spring 2021, Battersea Arts Centre, a venue（地点）in southwest London, introduced "pay what you can" for all its shows. The reason is simple—they believe that everyone should be able to be a part of the great work, regardless of(不管) their ability to pay. Should all shows be "paid what you can"?

Some supporters believe it's a good idea. In the 17th century when Shakespeare was writing his plays, everyone went to the theatre. The cheapest ticket in London was one penny. This is how shows should be open to everyone, no matter how much they earn. Paying what you can is in the spirit of Shakespeare's time, and it opens the arts to all. It also shows that many art venues are a type of charity(慈善机构) that provide public benefits and spread culture. That doesn't mean the show isn't good. 

However, this idea makes some people worried and some opponents(反对者) are against it. Society expects art for free—free art shows, free music, free videos. ____ For some people "pay what you can" would mean "pay what you want to"—nothing. It is expensive to put on a show. If the audience want to see a good show, they should pay a part of what it costs to put on. A survey by Arts Professional magazine found that many people a-void shows not because they are too expensive but be-cause they don't think they will enjoy themselves. Art venues should focus on making the best shows they can, and price the tickets to reflect the quality(质量).
