【写作】06-How to Write a Body/Main Paragraph 如何创作主体段

段落主旨句(一般是一个影响/结果) + 原因解释/降层解释/进一步的结果节水/对比解释/举例+ （如果需要可以重复主旨句）

可以只用其中一种扩展方法，也可以2-3种组合使用。

原因解释 + 举例解释
Using traditional cultures as money-making tourist attractions may destroy them. (This is) because the way they are originally performed needs to be altered to meet the needs of tourists. For example, in order to help audiences easily understand and happily enjoy the traditional Maori Haka dance in New Zealand, the moves have to be simplified and the show becomes more entertaining, which as a result leads to the loss of authenticity of the traditional art.

降层解释 + 进一步的结果
nother significant advantage is that the buyer can have more control over the process. Price comparison websites make it easier to find bargains, shopping can be done at any time of the day or night, and shoppers can browse for as long as they like without pressure from sales assistants. This means that shoppers can become more astute and knowledgeable about the products they are buying. Because of the greater competition involved in trading within a large market, sellers may have to improve the quality of their products.

只有举例
Technology can positively contribute to the keeping alive of traditional skills and ways of life. For example, the populations of some islands are too small to have normal schools. Rather than breaking up families by sending children to the mainland, education authorities have been able to use the Internet to deliver schooling online. In addition, the Internet, and modern refrigeration techniques, are being used to keep alive the traditional skills of producing salmon, because it can now be ordered from, and delivered to, anywhere in the world.
