　　英语说明文的写作方法（一）之二

　　ay，the first paragraph sets up the topic focus（主题所在）Next，the sentences in the body of a paragraph develop the topic sentence. Similarly，the body of an essay consists of a number of paragraphs that discuss and support the ideas given in the introductory（引导的）paragraph. Finally，a concluding sentence（结束句）whether a restatement，conclusion，or observationends the paragraph. The essay，too，has a concluding paragraph which ends the essay logically and satisfactorily. Although there are some exceptions（例外），most well written expository（说明文的）paragraphs and essays are similar in structure.

　　　　可以看出，在比较相同点的时候，常用到similarly，also，too，in the same case，in spite of the difference等这样的词语。

　　European Football and American Football

　　　　Although European football is the parent of American football，the two games show several major differences. European football，sometimes called association football or soccer，is played in 80 countries，making it the most widely played sport in the world. American football，on the other hand，is popular only in North America（the United States and Canada）.Soccer is played by eleven players with a round ball. Football，also played by eleven players in somewhat different positions（位置）on the field，is played with an elongated（拉长的）round ball. Soccer has little body contact（接触）between players and therefore needs no special protective equipment. Football，in which players make the greatest use of body contact to stop a running ball-carrier and his teammates，needs special protective equipment. In soccer，the ball is advanced toward the goal by kicking it or by butting（顶）it with the head. In American football，on the other hand，the ball is passed from hand to hand or carried in the hands across the opponent's（对手）goal. These are just a few of the features which distinguish（区别）association and American football.

　　　　这是一篇用比较不同点的手法写的说明文。从文章中可以看出：however，on the other hand，in contrast，but，nevertheless等表示转折的词语常用来引导对不同点的比较。[1][2]
