ho is Who
George is a policeman, and his son, Bill, is a high school student. One day they went into a cafe to have tea. When they sat down,Bill said,"Look! My classmates Logan, Kevin and Jason are over there!" He pointed to a table at the corner.
"But who is who?" said George."My guess is that the one drinking coke is Logan, the one wearing the hat is Kevin,and the one with a big face is Jason.
"Wrong. All wrong!" said Bill.
Just then, the big face got up from the table.
"It's time to go now,Kevin."he said. The two got up and all of them laft without another word.
"Shall I tell you who is who?" asked Bill
"No," said George. "I already know who is who…"
Complete George's words with Logan/Kevin/Jason:
"I already know who is who._______ was drinking,______had a big face, and _______ was wearing a hat."

首先可以从
"But who is who?" said George."My guess is that the one drinking coke is Logan, the one wearing the hat is Kevin,and the one with a big face is Jason.
"Wrong. All wrong!" said Bill
知道George全猜错了,那么可以得到下面这个表
the one drinking coke 可能是Kevin或者Jason
the one wearing the hat 可能是Logan或者Jason
the one with big face 可能是Logan或者Kevin

然后从Just then, the big face got up from the table.
"It's time to go now,Kevin."he said. The two got up and all of them laft without another word. (left你打成了laft,这里指出)
可以知道,big face不可能是Kevin,因为不可能对着别人说自己的名字,我们走了,而是叫其中一个人的名字,叫他们一起走
所以the one with big face是Logan,所以the one wearing the hat是Jason,the one drinking coke 是Kevin

所以"I already know who is who.___Kevin____ was drinking,__Logan____had a big face, and ____Jason___ was wearing a hat."
