Question

Mary is very clever and ___ worth teaching,but her brother is not.Look,he is now___ asleep in class.A very;very B much;very C well;very D well;fast

Answer 1

一般来说,worth前面可用well,really,very much,hardly, easily等词语修饰,但一般不用very修饰.
汉语的“睡得很熟”,英语习惯上用 fast [sound] asleep,而不说 very (much,very much) asleep 
所以~答案选D
