根据汉语翻译写出对应英语
你认为哪一张画最好看?
Which ( )( )( )is the nicest picture.
我写Which (picture) (you) (think)( is the nicest picture到底对不对?我觉的是对的
但是正确答案是:Which( do) (you) (think) is the nicest picture
是不是应该写Which picture that you think is the nicest picture?

Which picture do you think,之所以要填do是因为原句中还未有动词作谓语,所以要补充一个do用作谓语.
