你可以用There are many books in our school library.
　　但是还从没见过many跟在句尾的= =many+名词复数哦,
不过口语中可以跟在句尾
A:There are too many bad movies these days.
B:Yes,way too many!
————————————————————
至于第二个句子我感觉是对的吧,因为我背的课文里就有一句类似的
The old man with the white stick was blind.这个拿着白手杖的老人是个盲人
为了避免错误,可以用绝对对的一种形式
The horse is blind in the right eye.
这匹马的右眼瞎了.
