推展段落方法之一事实与数据法 事实与数据法： 事实(a fact)是可以客观证实的事情。例如：“The sunrises in the east.”是个事 实。“Oil and water do not mix.”也是个事实。两者都可以通过实验证明是真实 的。但是“Eating carrots improves eyesight.”也许是真实也许是不真实的。这不 是个事实，是一种看法(opinion)。数据(a statistic)是一个数字事实(a numeral fact),用于给某一主题提供有意义的信息。例如：There are twenty一five students in the class..”是一个数据。 示范段落1 The term population explosion is usually applied to the rapid growth of population over the last three centuries.In the two hundred years from 1650 to 1850,world population doubled and reached its first billion.In the next eighty years,it doubled again,and by 1975,it had doubled once more to a total of 4 billion.By the year 2000 it is estimated that it will exceed 6 billion and possibly approach 7 billion unless there is a major reduction in birth rates or a major increase in death rates 示范段落分析 主题句：The term population explosion is usually applied to the rapid growth of population over the last three centuries. 提供信息： 数据1：1650-1850；double,reach1 billion 数据2：1850-1930；double again,reach2 billion 数据3：1930-1975；double again,reach4 billion 数据4：1975一2000；exceed6 billion,approach7 billion 示范段落2 A snake is a strange animal.It walks on its ribs and it smells with its tongue.Since its teeth are sharp like needles and not good for chewing,it swallows its food whole. 示范段落分析 主题句：A snake is a strange animal, 1:walks with its ribs and smells with its tongue 事实2：swallows its food whole 关于如何写事实与数据段落的建议 1)不要把事实与看法混为一谈 事实是真实的，因为它们已被证据证实。然而看法只是人们的主观想法，不一定 真实。因此，记住用事实而不是用看法支持你的观点。 2)不要使用不相关的数据 如果你为了增加观点的可信度而使用不相关的数据，即使这些数据是真实的，也 会引起误解。推展段落方法之——事实与数据法 事实与数据法： 事实（a fact）是可以客观证实的事情。例如：“The sunrises in the east．”是个事 实。“Oil and water do not mix．” 也是个事实。两者都可以通过实验证明是真实 的。但是“Eating carrots improves eyesight．”也许是真实也许是不真实的。这不 是个事实，是一种看法（opinion）。数据（a statistic）是一个数字事实（a numeral fact），用于给某一主题提供有意义的信息。例如：There are twenty－five students in the class．”是一个数据。 示范段落 1 The term population explosion is usually applied to the rapid growth of population over the last three centuries.
