闡述段的句子潤色和修飾
方法一：修飾主系表中的is
如果只寫it is+名詞，句子的結構就比較單調(diào)，如果我們把is的寫法替換為一些被動結構，效果也不一樣，具體的方法如下：
1）It is nothing but+名詞
2）It has been well received as+形容詞的級+名詞
3）It is been commonly accepted as one of +形容詞級+名詞s
4）It is considered+名詞
5）It can be regarded as+名詞
6）It can be seen as +名詞
以上其中句子結構，選取任何一種，解決it is 名詞，結構簡單，字數(shù)過少的問題。其中It is nothing more than和It is nothing but可以用于語氣的增強，后面五種寫法可以讓主系表呈現(xiàn)出書面風格。我們可以通過對比，看一看寫作的效果。
比如你想表達"英特網(wǎng)是一種娛樂方式"這個意思，如果不會使用句子結構，就只能寫成It is a form of entertainment。但是如果選用上述句子結構，就可以分別寫成It is nothing but a major means of entertainment. 或者Internet has been well received as the most popular means of entertainment，或者Internet has been commonly accepted as one of the most popular forms of entertainments。大家可以對比一下，這幾個寫法，是不是比it is a form of entertainment更像書面表達呢？
