个人观点供参考：
     1.with不行，表示伴随，改变意思了。
       each，强调型独立主格结构，解释说明
       supported修饰roof
     2。especially和specially的区别，以前讨论过的。大概记得especially比specially表达“特殊”意思更强。
       另外：the capability of the respiratory system to deal不如the respiratory system’s ability to deal好，同样表达“能力”的话，应该是ability优先考虑，除非还有其他错误

谢谢dreadpower的回答。
再问：
2。‘S不是用在人所有格吗？
    the capability of 和 ability to 有没有实质区别？
   对这题，大家有没有别的看法？

dreadpower

：）厚着脸皮再答：2。‘S不是用在人所有格吗？

      这点不是绝对的，不要以此为判断排除选项的标准！

谢谢 dreadpower 又一次的耐心解答。
同时坚持问这个问题：
    the capability of 和 ability to 有没有实质区别？
   对这题，大家有没有别的看法？

这两题好像以前都问过，你要不要试试用新版题号搜寻。
一般来说，can 比 ability 或capability都要好。
这两个都当名词。有惯用的语法句型，何妨查查字典先。

capability 与 ability 看不出来有明显的使用区别，
但有些情况似乎用capability较为适当：
These tests are beyond the capability (= ability) of an average 12-year-old.

2 : 表a feature or faculty capable of development : POTENTIALITY
a child's language capability
I have a good knowledge of French, but simultaneous translation is beyond my capabilities.

3 : 表the facility or potential for an indicated use or deployment
*the capability of a metal to be fused*
*nuclear capability*

用法上
(ability, capability) to V
(ability, capability) of N
单独当名词使用都可

此外
形容人有能力一般用 ability    (able to do)
形容军事力量一般用 capability  (can do)

请多补充。谢谢！

好像有以下固定用法．．．
－ability of somebody to do something
－capability for doing something

I guess D could be right if it had used "for dealing with" instead of "to deal with".
nn, any comments?
