1.(As sweentens),there is very (small)difference between honey and sucrose, (although) the former does contain minimal (quanties of) vitamins, minerals, and amino acids.
为什么选 b? 不是a?主语是"there",还可以用as?

2.It (is said)that no potential frontier has (such) fired the imagination or challenged the (ingenuity) of humankind (as has) space?
答案是b,我选d.为什么又错了

请高人指点，我的语法很糟糕。

anyone comfirm it?

Agree with 2楼. But 2) should change 'such' --> 'so'.

yes, such------so

honey and sucrose has nearly no difference in sweeetens, so use negative word "little".
Consider the whole sentence.

It (is said)that no potential frontier has (such) fired the imagination or challenged the (ingenuity) of humankind (as has) space?

as 这里是当连接词用吗？为什麽不是用having?

lucyyyh · 发表于 2003-9-27 10:02:00

这是一个并列结构,原型是是not so...as...的结构.as之后的v.应该与比较对象(potentialfrontier) 的谓语v.一致,这里用了倒装结构,所以最后是as has space(= as spac has)
