A guy was carrying a box when he met his friend.

He said，"Guess how many cakes I have in this box."

He added, "Guess correctly and I'll give you both of them!"

Notes:

1. A guy was carrying a box when he met his friend.

一个男人遇到他朋友时正巧拿着一个盒子。

2. He said，"Guess how many cakes I have in this box."

他说：“猜猜我这个盒子里有几块蛋糕。”

问“我这个盒子里有几块蛋糕?”应该是"Hmv many cakes do I have in this box?"，但由于在本句中是做guess的宾语，由此用陈述句的句式.句末也不用问号。

3. He added, "Guess correctly and I'll give you both of them!"

他又补充说：“猜对的话，我会把这两块都送給你!”
