1/31要考了, 讨论新JJ一题:

Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse.

1. so hard that it makes burrowing difficult or so soft that it could cause

2. hard enough to make burrowing difficult or soft enough as to cause

3. so hard as to make burrowing difficult or soft enough so it causes

4. as hard as to make burrowing difficult or as soft as to cause

5. too hard, making burrowing difficult, nor too soft, so as to cause

我觉得是B, 可是不太平行.... A看着也很对啊, 请指教!

10秒钟内判断肯定是D。意思正确，平行优美。

可以简单看成“it is not hard to make burrowing difficult or not soft to cause tunnels to collapse.

该句从意思上判断最好：

研究人员假设花岗岩泥土是沙漠乌龟的最好的建筑材料，因为这种材料不会硬到无法在里面打洞，也不会软到让乌龟的“隧道”塌陷。

太谢谢了, CD牛人就是多啊....

不客气，我也很为SR头疼啊，在这个版面找“宝贝”学习呢。

祝你好运！

我觉得(D)不对，

(A)个人倾向于此答案，it在此句中都是指代granitic soil，两个so...that...对称平行；

(B)enough在so that/so as to中基本都是错误选项，另外or后面的as to在没有so的情况下也是不对的；

(C)or前后不对称，前面用了so...as to，而后面用了adj.+ enough,还莫名其妙地多了so；

(D)as...as...表示和...一样...，而so that/so as to表示如此以至于

(E)错误就太多了，not...nor结构，没见过，前后也不对称，前面用making，后面用so as to。

一家之言，仅供参考。

我觉得肯定是A！前面几位说的理由我赞同，再加一点：从逻辑意思上看也应该是A；就是说，从逻辑意思上来说，这里不能说as hard as, 也不能说hard enough to...（请仔细体会）

最近做GMATprep做吐血了，发现：做语法题时，逻辑合理性真的是越来越重要，甚至比平行更重要！也许是新的趋势吧
