do you know和do you think的区别?
how many apples are there on the tree do you know?
是Do you know how many apples are there on the tree
还是Do you know how many apples there are on the tree
do you think how many apples are there on the tree
这2句意思重点在于
第1句问知道不知道,2句(do you think)是主问how many apples are there on the tree
若换成can you see?
...再有你说的那么简单就好了...
