38、写作中如何组织段落(1)技巧点拨英语文章的段落都由主题句(Topic Sentence)和支持句(Supporting Sentence)构成。主题句概括全段意思，表示段落的中心思想。支持句必须围绕这个主题句的意义加以阐明、补充、发挥或论证。主题句在段落中的位置和表示法：1主题句写在段落的开端，后面的支持句为主题句提供论证和细节，初学者以使用此法为宜。如：Americans make no distinction in greeting friends，acquaintances，elders，or superiors.When Americans see someone they know

39、only by sight，they are likely to say“Hi”in all cases.This does not mean that they have no more regard for friends than for casual acquaintances.It only means that“Hi”serves as greeting for both.2主题句写在段落末尾，前面都是提供细节的支持句，内容逐渐收拢，最后用一句总结性的主题句加以概括。如：Americans might be embarrassed because their Japanese fr

42、”when they meet；Japanese bow.Many American men open doors for women；Japanese men do not.On the surface，it appears that good manners in America are not good manners in Japan，and in a way this is true.But in any country，the only manners that are important are those involving one persons behavior towar

43、d another person.In all countries it is good manners to behave considerately toward others and bad manners not to.It is only the way of behaving that differs from country to country.4主题句写在段落中间或其它地方。此时，要根据上下文的意思才能确定该段落中体现中心思想的句子。如：Californians and New Englanders are both American.They speak the same

44、language and abide by the same federal laws.But they are very different in their ways of life.Mobilityboth physical and psychologicalhas made a great impression on the culture of Californians；lack of mobility is the mark of the customs and morality of New Englanders.活学活用划出下列段落的主题句A Last Monday,our c
