三年前的一个假日,我去外婆家玩。外婆见我来了,买了一个又大又吓人的东西放在桌上。我当时并不知道那东西是什么,只记得摸上去手很痛。我指了指那玩意儿,问道:“外婆,这是什么?”“手榴弹!”外婆笑着说。听了这话,我吓出了一身冷汗:手榴弹可是会爆炸的,我还是把它扔了吧! A holiday three years ago, I went to grandma’s house to play. Grandma saw me coming, bought a big, scary thing on the table. At that time, I did not know what was the thing, just remember to feel painful. I pointed to the stuff and asked: “Grandmother, what is this?” “Grenade!” Said the grandmother with a smile. After listening to this, I scared out of a cold sweat: grenades can explode, I still throw it!
