average sth表示普通的某物，类似于general sth，如：
R：Tech COMPANIES are as likely as the AVERAGE COMPANY to fail.科技公司和普通公司倒闭的概率是一样的。W：Tech COMPANIES are as likely as the INDUSTRY AVERAGE to fail. (Compare apples to apples.)
Americans of Middle Eastern descent were twice as likely as the average American to be self-employed. 有中东血统的美国人创业的可能性是普通美国人的两倍。
the national average看上去像一个统计指标，不指人，不能与前面的Americans进行比较。

请问为什么A解释说found后用doing或者从句，但E中说find吼只能用从句呀？为什么doing不可以呢？ 谢谢！
A it 没有指代 ， both as well as错误 句子重心不对 B逻辑主语不对 IT 没有指代 C没有谓语动词 to be不对 it无指代 E句子重心不对
不好意思，点错了，应该是从语义出发，find后面应该接一个句子，也就是能飞很多航线这件事，如果是 doing ，那么核心意思在doing
