Once there was a little boy.He got angry easily.His father gave (36 A.him,结构：give sb.sth.人为间接宾语,要用宾格)some nails
and told him:"When you get （37.C.angry 下文40处提示发泄怒气）,put a nail into the wall."
On the first day,the boy (38.B.put 文章的说的是过去的事情,put的过去形势还是put) 37 nails into the wall.The next day,he put in （39.C.fewer,钉子 nail是可数名词,这里是与第一天比较） nails.A few days later,he found it much （40.B.easier 副词much放在形容词比较级前表示容易得多）not to get angry.After a while,the boy was happy every day.
Then,his father asked him to （41.A.take out 表示拔出来） a nail each day if he didn't get angry.After some time,all the （42.D.nails 指钉子全部被拔出） were gone.
Then the father took the boy to the wall and said:"Well done,son.But,look,the wall is full of holes (洞).It will （43.D.never 拔出钉子后“永远”不会再出现同样的情形） be the same.When you say things in anger,they leave a scar (伤疤) in people's hearts.No matter how many times you say （44.A.good-bye 无论说多少次“再见”）,the scars will always be there."
It's not nice （45.B.to leave； 句型It's not nice to do sth.其中 it 是形式主语,不定式是事实上的主语） scars in people's hearts.So please hold back your anger.Think before you say angry things to friends and family.
