为什么Now I know a lot about public signs中,不用a lot of 而用a lot about 呢?

不一样的意思.
Now I know a lot about public signs.意思是我现在懂得了很多关于public signs的知识（东西）,与public signs有关的东西.
Now I know a lot of public signs.意思是我现在懂得（认识）了很多public signs（指public signs本身）,就是会辨别各种各样,不同的public signs.

为什么Now I know a lot about public signs中,不用a lot of 而用a lot a Now she ____(know) a lot about public signs. I know a lot about public signs.改成否定句I ()()a lot about publi I,public,now,know,signs,about,lot,a 连词成句 now l know a lot about public now l know a lot of about the signs哪里错了改否定句:l konw a lot about public signs There( ) a lot of public signs in the park now. A.are B.is C a lot of signs here I public a know sings lot about Now连词成句 know a lot about know a lot about computer,句中about为什么不用of?
