Internet shopping is a new way of shopping. Nowadays, you can shop for just about anything from your armchair. All you need is a computer which is linked to the Internet. Shopping on the Internet is becoming increasingly popular. In the United States, people spent over US $2.5 billion on Internet shopping in 1998. This figure is expected to reach US $11 billion by the year 2004.

People can shop for a variety of products on the Internet. Physical products include items such as books, CDs, clothes and food. These types of products are the most common purchases through the Internet. You can also buy information products such as on-line news or magazine stories, or you can download computer software through the Internet. Services such as booking airline tickets, reserving hotels or renting cars are also available on the Internet. You can also go shopping on the Internet for entertainment services and take part in on-line games.

Internet shopping offers a number of benefits for the shopper. The most important advantage is convenience. You can shop when you like as the on-line shops are open 24 hours a day and you don’t have to queue with other shoppers at the checkout counters. Secondly, it is easy to find what you are looking for on the Internet. Even out-of-print books may be ordered on line. Finally, it is often cheaper to buy goods through the Internet, and you can tell the shop exactly what you want.

The main disadvantage of Internet shopping is that you cannot actually see the products you are buying or check their quality. Also, many people enjoy shopping in the city and miss the opportunity to talk to friends. Some people are worried about paying for goods using credit cards, so Internet companies are now finding ways to make on-line payment safe.

Internet shopping is sure to become more and more popular in the years ahead. It promises to change the way we buy all kinds of things—from tonight’s dinner to a new car.

On-line news and magazine stories are ().

A. the most popular products on the Internet

B. not yet available on the Internet

C. everywhere on the Internet and free to download

D. information products available on the Internet

我们常用各种多边形地砖铺砌成美丽的图案,也就是说.使用给定的某些多边形,能够拼成一个平面图形,既不留一丝空白,又不互相重叠。这在几何里叫做平面密铺(镶嵌).我们知道.当围绕一点拼在一起的几个多边形的内角和为360°时,就能够拼成一个平面图形,某校研究性学习小组研究平面密铺的问题.其中在探究用两种边长相等的正多边形做平面密铺的情形时用了以下方法:  

如果用x个正三角形,y 个正六边形进行平面密铺.可得60°×x+120°×y=360°,化简得x+2y=6.因为x、y都是正整数。所以只有当x=2,y=2或x=4,y=1时上 式才成立,即2个正三角形和2个正六边形或1个正六边形可以拼成一个无缝隙、不重叠的平面图形。如图①②③。   

 请你依照上面的方法研究用变长相等的x个正三角形和y个正方形进行平面密铺的情形,并按①中给出的正方形和正三角形的大小大致画出密铺后的图形的示意图(只要画出一种图形即可).
