Honestly, none of them sound 100% correct to my ear. I think these two are technically correct, but they don't sound "American" to me: Don’t read such books that you don’t understand. He is such a clever boy that we all like him. I think the word "such" is uncommonly used in American English. I think the only time I use it to say: "Don't be such an idiot" or "Don't be such a jerk" Adding anything more to sentence sounds weird and makes me want to think of a simpler way to say it.
