英語四級(jí)寫作錦囊關(guān)鍵句：453. There are some good reasons for

453. There are some good reasons for...to do...

譯文

……做……是有一些原因的。

點(diǎn)睛

本句型是典型的議論文中間部分的起始句型。在本句型的引導(dǎo)下，后面就可以一一敘述原因了。本句型中的some可以根據(jù)語境替換成數(shù)詞many，two，three等。如果把some替換成數(shù)詞one，則應(yīng)當(dāng)注意：there be句型中的be以及reasons的單復(fù)數(shù)形式都要隨之改變。在替換的時(shí)候需要注意：for后面應(yīng)該接某人或者某組織的名稱。to do則應(yīng)該根據(jù)語境進(jìn)行相應(yīng)的變化。本句型還可以變化為there are some reasons for sth.，表示“某事物是有原因的”。
