Guangzhou is becoming ___ after the 2010 Asia Games A.Beautiful B.most beautiful C.more beautiful

D.more and more beautiful
become+比较级
beautiful比较级：more beautiful
更加漂亮.D.more and more beautiful
【欢迎追问,】但是答案中写的是C我只是想问C和D两项的区别应该是become more and more beautiful.e.g.Shenzhen becomes more and more beautiful.因为一般使用的时候become总共加更加...，虽然more beautiful语法和D都对，但是D更加常见一些，比如become hotter and hotter
