may not be 是常见的规范说法,may be not 这种说法也有,不如前者常见和规范。
The car may not be much to look at (=it does not look good) but it's very reliable.这辆车也许看上去不怎么样,但性能非常可靠。
这句话能否改成:The car may be not
much to look at (=it does not look good) but it's very reliable.因为下面这句话:He's not much to look at, but he has a wonderful
personality.他长相不怎么好看,但性格很好。 Not在be后面
