My view on knowledge英语作文点评

　　My view on knowledge

Samuel johnson once said,”General principles must come from books ,which,however ,must be brought to the test of real life”.

First,what i want to emphasis is that I can’t agree with his remarks any more lmed in variety of books,general principles are easily accessible to us,including knowledge about science 、society 、botany、zoology 、philosophy and so on.

However,as the saying goes,”Practice is the sole criterion for testing truth .” Other than getting general principles from books ,what’s of more significance is to put them into practice. Only after testing them in daily lives can we identify which one works or not,no matter how brilliant it , though dealing with problems using those principles ,we have the ability to know which one can benefit us more . What’s more ,once you get to familiar with knowledge by putting them into use,you’ll have a better understand of knowledge e is no doubt that you will sublimate the knowledge you’ve got from books .

In short ,attention should not be paid to acquire knowledge from books ’s the application of knowledge we got from books that counts.

点评：

在文章的开头，运用景物描写，为文中所写的人和事渲染环境、提供背景，能给人以美好清新的印象。写景的内容，可以是天气情况、自然风光、建筑设施，可以是动景静景、远景近景、美景劣景、大景小景等。小朋友们都爱好景物，也最喜欢写景，这种开头，会一下子抓住读者，有助于增强读者的阅读兴趣。

当然，开头运用景物描写，要注意三个方面：一是写景的文字不能过多，不能一写到景物，就没完没了，无始无终，结果，景物写了很多，显得头大身子小，文章不匀称；二是要重点突出，主要景物多写一些，次要景物点一下即可，不能样样都写，结果都没有写好；三是写景是为人和事服务的，要与文中所写的人和事有密切关联，景与人事不能脱节，更不能把景物写成了文章的累赘。

请看下面这个开头：

瓦蓝瓦蓝的天，丝丝缕缕的轻云如烟般缭绕，夕阳的光辉洒满田间，万条金线接天浮动，玫瑰色的光彩，映在绿得发黑的菜上，叶面上像抹了一层油，亮闪闪的。

这段文字，是习作《路过天堂》的开头，用的全是景物描写，主要是仰视之景，夕阳下的.美景，蓝天、轻云、夕照的光彩、碧绿的菜叶，渲染了美好的情境，为写“我”下文“路过天堂寨”提供了优美的环境背景。读后有身临其境之感，令人心驰神往，显然是一个好的开头。
