英語四六級不會直接考察語法,但是聽力中需要聽句子,閱讀中需要句子,作文中需要寫句子,而語法是句子的骨架,有句子的地方就有語法,所以語法基礎是四六級做題之根本。下面是四級語法辨析:healthy與healthful用法辨析的資料,希望對你有所幫助!
1. healthy 有兩個意思,一是指“人本身健康的”,二是指“有益于健康的”。如:
Good food keeps you healthy. 好的飲食使你健康。
Cycling is certainly healthier than driving. 騎車肯定比開車有利于健康。
有時用于比喻義。如:
That book is not healthy reading for children. 那本書供小孩讀不健康。
2. healthful通常只表示“有益于健康的”。如:
Doing morning exercises is very healthful. 做早操對健康很有益。
Why don't you eat such healthy [healthful] foods? 你為什么不吃那些有益于健康的食物?
此詞在現(xiàn)代英語中用得不多(已屬過時用法),一般用healthy代替。
