这几天,班里感冒的人很多,我也被传染了。妈妈带我去医院,医生说要挂水。在打吊针前,医生先用白色的棉花在我的手背上擦了一下。擦过的手背上有凉凉的感觉,空气中还有一种特殊的气味。 These days, there are many people in my class who have a cold and I have also been infected. Mom took me to the hospital, the doctor said to hang water. The doctor first wiped the back of my hand with white cotton on the back of the needle. Rubbed the back of a cool feeling, there is a special smell in the air.
