ability to do / capability of doing - 两个习惯表达，但是其他条件相同时优先选前者

A - ability to do / because 都正确

B - capability of doing 正确/ because of 结构太笨拙

C - capability of sth to do 注意这里的of是修饰capability属性的，不是我们上述的动词结构，所以错了

D - 同C

E - 同B

especially vs specially 在Logman上给出的解释：

Especially is most often used to emphasize something, or to say that something is more worth mentioning or more important than the other things you are talking about: It can be especially difficult for drivers to see cyclists at night. | The town is especially crowded in the summer (=much more than in winter). I hate interruptions, especially when I'm trying to work (=I do not mind as much at other times). Specially is usually used when you do something that is different from what you usually do for a particular purpose. It is often used with the passive form of a verb: a specially made/designed/adapted etc car | I bought it specially for you
