1.Fathers often think {it} their duty to earn more money for their family
2.Good health is [something] most people take for granted——until they lose it
3.It's proved that there are no extra health benefits from eating organic food rather than [that] grown on ordinary farms.
问题:
1、都是特指,为什么1题不用that,3题不用it?
2、为什么是smothing?
第二题是根据翻译填单词。【身体健康是大多数人都认为理所当然的事情——直到失去它】
追答抱歉这个在我的水平范围外了,仅仅只是翻译,我觉得what也可以填进去
这个地方是一个名词性从句,我觉着一般能引导这类从句的无实意引导词都能放进去
谢了
(1)that构成的是宾语从句 从后面看不是一个完整句子 所以不用
(3)that有指向性 叫做指示代词 这里指向普通农场的作物
不定代词 不定 good health是比较模糊的一个概念
