Fashions in clothes change for almost as many different reasons as there are fashions. Among the chief causes are changes in the kind of work we do, the cost and availability of the materials used and the invention of new materials, such as manmade fibers. The attitude of different societies toward the body and how much of it should be displayed is also important. For example, if a girl in the Middle Ages had worn a miniskirt she would have been regarded as either mad or wicked, social standards change from age to age from country to country. There have been dramatic changes in fashion in our century, partly owing to the availability of new and cheap rnaterials and partly because this generation believes those clothes should be a matter of personal choice, and fortable ils well ils attractive. Many of the fussy clothes of our ancestors, often requiring yards and yards of material, would be too expensive to produce today. They would also be unsuited to modern living imagine cycling in a crinoline. Great wars often influence fashions. During the Second World War the style of women39。s clothes became military. Jackets, for instance, had square and padded shoulders. After the war, this fashion changed to the voluminous, more femine, new look of Dior, the great French designer. Another big change happened after the First World War. Women who had worked for the first time with men in the factories durinng the wars began to dress with greater freedom and started to wear short skirts. Today, what we wear is largely a matter of personal choice, convenience and what we can afford. 作者在第一段開門見山指出服飾變化 有種種原因，然后按時(shí)間順序，具體說明服飾變化的過程及原因。最后一段指出如今人們著裝變化的主要原因。 How to Make a Sun Scope To build your own sun scope, get a carton and cut a hole in one side, big enough to poke your head through. Paste white paper on the inside surface that you will be facing. Then punch a pinhole into the opposite side high enough so that the little shaft of light will miss your head. For a sharper image you can make a better pinhole by cutting a oneinchsquare hole in the carton, taping a place of aluminum fold over this hole, and then making the pinhole in the foil. Finally, tape the box shut and cover all light leaks with black tape. Equality Between Men and Women At present, more and more people think that men and women should enjoy equal rights. Many countries even have passed laws to guarantee such equality between different sexes. Accordingly, there are now no longer certain jobs or certain places that are closed to women. The number of businesswomen, female doctors, scientists and leaders is considerably increasing. There are three rnain reasons for the improvement of women39。s social position. First, women themselves have been persistently struggling for the equality. Second, men also realize that women are not born inferior to them. Women can do a great many things as well as or even better than men. Third, the social development has produced a great demand for women39。s participation in every field. In spite of these changes the liberation of women has not been pletely realized. Prejudice against women is deeply rooted in some people39。s mind, especially in the distant rural areas. So, our mankind should take further painstaking efforts to really realize the equality. 這篇文章的第二段，就是非常典型的用 first， second， third 為次序詞，列舉三方面細(xì)節(jié)進(jìn)行論證的例子。 Traffic Accidents In China This table shows the traffic accidents from January to June 1985 in China. We can see from it that traffic accidents are being such a serious problem that more and more people are injured or killed. As is shown in the table, from January to June, a total of 94,670 people were injured and 2,827 people were killed. We can find that traffic accidents have been on the increase all the time. In Jan, there were only 13,905 people injured while in June the number went up to 17,151. In January, there were only 230 people killed, but in June, the number increased to 700. The rise not only shows that traffic accidents are being a threat to people39。s lives and properties, but also shows that problems existed in the traffic systems. It is now very urgent for us to take effective measures to bring them under control. On Punctuality(論守時(shí) ) 1．什么叫守時(shí) ? 2．不守時(shí)有哪些害處 ? 3．如何才能守時(shí) ?

A man who gets up at six o39。clock every morning is punctual A man who has promised to call on a friend at five o39。clock in the afternoon and actually does so at that hour is also punctual. Punctuality is a good habit, and unpunctuality is, of course, a bad one. A few minutes delay may not be a serious matter. But it may have bad results. Getting up five minutes later than usual may upset the plan of the day. Calling on a friend five minutes later than the appointed time may cause him some unexpecte
