答案及解析:
1.Have-Are
dress “某人着装，穿衣”的用法是 somebody be dressed/get dressed。
2.Can you-they
根据上下文可以看出这里是说在公众面前演讲你会注意你在公众面前的形象，穿得是否得体，头发是否整齐，比人会不会看出你正紧张得出汗等问题。所以此处的人称代词应该是“他们(别人，公众)”，而不是指“你自己”。
3.heard^-of/about
这里意思是说“你听说过吗?"
4.as-like
这里用like 表示“像……一样”，意义上才合理。As作为介词时意思是“作为”。
5.drew-paid
根据上下文，这里是说你有没有注意到其他在公众场合讲演的人，而不是说你引起什么人的注意。
6.the-/; in-to
the public 是指人，“公众，民众”，所以可以说speak to the public。In public 是固定用法，指“公开的，公然。
7.^qualities-the
qualities后面紧跟着限定性定语从句，所以是特指，前面需要加定冠词。
8.went改为goes
这里是时态保持一致的问题。此处的前后都是用的一般现在时，所以这里也要用一般现在时。
9.has改为have
humans是可数名词复数，所以后面的谓语动词要和主语保持一致。
10.^impact—an
impact 作“影响”解时，是可数名词，通常都用单数形式，所以impact前面需要一个不定冠词an，此处“产生影响”是make an impact.后面的it's a lasting one 已经给了我们解题的线索，a lasting one 就是指 a lasting impact。
