。各種展開段落的方法綜合在一個(gè)段落里全部是為表達(dá)主題服務(wù)的。接下來用了比較法,說明熱氣球要比充氣氣球安全;同時(shí),作者還用了因果分析法說明熱氣球以其安全性能強(qiáng)為美國(guó)人青睞。Balloons have been used for sports for about 100 years. There are two kinds of sports balloons: gas and hot fire. Hot balloons are preferred by most balloonists in the United States because of their safety. They are also cheaper, and easier to manage than gas balloons. Despite the ease of operation on a balloon, pilots must watch the weather carefully. Sport balloon flights are best early in the morning or late in the afternoon, when the wine is light. Over the years balloonists have tried unsuccessfully to cross the Atlantic Ocean. It wasn’t until 1978 that three American balloonists succeeded. It took them just six days to make their trip from their home in the United States to Paris, France. Their voyage captured the imagination of the whole world.這里的第二句話是段落的主題句。九、綜合法綜合法是指根據(jù)行文的需要采用兩種或兩種以上的方法來展開段落的寫作方法。然后集中筆墨闡明結(jié)果,在這里即problems。也有一些段落結(jié)果是顯而易見的,就集中說明原因;有的段落正好相反,就集中說明結(jié)果,因?yàn)樵虿谎宰悦?。可以先講原因,后給結(jié)果,也可以先給結(jié)果,后講原因。A good name is better than riches.——聲譽(yù)勝于財(cái)富。作者在段落首句里用一個(gè)which引導(dǎo)的定語從句直接對(duì)Poetry進(jìn)行定義、解釋。Poetry is a branch of literature which explores ideas, emotions, and experiences in a distinctive form and style. Poetry, sometimes called “verse”, depends greatly on the natural rhythms and sounds of language for its special effects. Poetry, even more than prose (all other writings), depends on precise and suggestive wording. In other words, a poem says much in little space. Poetry differs from prose in obvious ways, also. Most often the first word of every line begins with a capital letter, even in the middle of a sentence. Poems sometimes contain rhyme, and often they have a particular rhythm, like music.本段通過下定義的方法說明什么是詩歌。段落一開始,作者先指出,愛是一個(gè)常見的字眼,意義很泛。定義法常用于說明、描寫和論證,以提供更多的具體解釋來說明某一概念或術(shù)語。然后,作者運(yùn)用One is the machine scored “objective type”, Another is the “pletion type”,” And the third type is the essay examination” 來清楚地將考試分類闡述,段落脈絡(luò)一目了然,層次十分分明。Examinations fall into three kinds. One is the machine scored “objective” type. In an objective test, the students answer questions by deciding on best choice among a number of alternatives given. Another is the “pletion” type. This kind of examination requires the students to add a word or phrase to plete a sentence. And the third type is the essay examination, in which the students are asked to write a position on a given topic. All these kinds of examinations are designed to reveal what a student may have learned in any particular course.本段采用分類法來展開段落。There are two kinds of sports: “amateur” and “professional”. Amateur athletes do not receive money for peting in sports. Olympic athletes, for example, are amat
