These days, many people begin     31     (try) a new way of doing shopping through the Internet. They are very     32     (interest) in it. Why is it becoming more and more popular now? There are some     33     (reason). First, more and more people have     34     own computers. So it is possible for many of them to do shopping through the Internet.     35    , shopping through the Internet can save them some money and a lot of time. Third, they don't need to go to the shop     36     (they). Because     37     these good facts, lots of people like going shopping on the Internet.

However, some people don't like this new way of     38     (shop). They are     39     (worry) about the safety of shopping online. People can only see the pictures of a product on the Internet. And they can't enjoy the joy of buying things in a large supermarket or a wonderful shopping center. These are the reasons     40     they do not like it.

But I think more and more people will like this new kind of shopping in the future.

Let us suppose (假设) it is now about A. D. 2060. People go to the moon every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe.

What are people eating now? People are still eating food. But many foods now come in pill (药丸) form. Farming, of course, is very highly developed. Very few people have to work on the farm. People are now largely vegetarians (素食者) and we are healthier both in our bodies and in our minds, and we don't have any diseases (疾病). No one has to be ill any more.
