GWD 26-3:哪位NN告诉我, ALLOW THAT 用法, SO THAT, SO 的区别...

GWD 26-5

The particular design of muscles and bones in the neck and limbs of the turtle allow

that it can draw in its exposed parts such that an attacker can find nothing

but hard shell to bite.

A.     allow that it can draw in its exposed parts such that

B.     allow it to draw in its exposed parts, and so

C.     allows for it to draw in its exposed parts and that

D.     allows that it can draw in its exposed parts, and so

E.      allows it to draw in its exposed parts, so that

不知道LZ问allow that的用法的意思，allow that就是这样用呀。

so that与so做连词表达的意思是一样的。

建议LZ自己准备一本longman字典和语法书。

我认为答案应该是E

查过字典後

allow that翻译为承认

A allow B to do sth翻译成A允许B做某事

做如此翻译後D选项变成乌龟「承认」自己的露在龟壳外的身体部位缩进来，这样句意不是很怪吗？
