379. The reason why so many children like to eat this new brand of biscuit is that it is particularly sweet and crisp.

譯文　這么多小孩喜歡吃這種新品牌的餅干，是因為它特別甜、特別脆。

點睛　the reason why...是表示原因的固定句型，其中的why不可以用that替換。如：

The reason why I did it is obvious. 我這樣做的理由是顯而易見的。

說明reason的內(nèi)容時不能用because。如：

The reason why he was late was that he was ill. 他之所以遲到，是因為他病了。

有時，the reason后也可接介詞for，如上句又可改為：

The reason for his being late was that he was ill.
