E.      In an attempt at the development of a strong strain of silk-producing insects, a French scientist, importing the gypsy moth from Europe into Massachusetts in 1869 in order to cross gypsy moths and adult silkworms.

此题为何不能选A

第2题答案是不是D?

A中crossing gypsy moths with adult silkworms的逻辑主语很容易误认为是 the gypsy moth

而且，in an attempt at developing 感觉蛮罗嗦的...

个人观点

第1题中的especially和specially词义有区别，especially是相同类型东西的比较，specially是不同类型东西的比较，Sulfur dioxide属于pollutant所以用especially更好。

第2题crossing gypsy moths with adult silkworms这部分动作应该是由主语发出的，而主语是the gypsy moth ，所以不好。

个人见解，还请其它NN指教

和诸位探讨:

1)查WEBSTER和longman后发现 ability和capability 都可以用为: ability to do sth , capability to do sth 的形式, 虽然在某些时候especially 与specially可以互换,但是在书面语中especially语气更重,因此选A

2)选D.同意上两位的看法, 另外attempt 是否应该与to 搭配而非 at .

请大家指教!

在词义上capability和ability也是不同的，朗文字典上的解释

capability:the natural ability, skill, or power that makes a machine, person, or organization able to do something, especially something difficult

ability:1[countable] the state of being able to do something

         2[uncountable and countable]someone's level of skill at doing something

longman:

attempt n.

attempt at (doing) something
her feeble attempt at humour
