[填空题]Going down a hill is like ______.

[单项选择]It’s easier to go clown a hill than to climb up a hill, so it is easier to fall into bad habits than into good ones.
Bad habits do not come suddenly. They come little by little while people don’t notice their danger. Schoolboys first pick up a few bad habits in schools and on the streets. When they can’t finish their homework, they copy from their classmates, If they see bigger boys smoking, they also want to have a try. When they get bigger, the habits become so strong that they can’t get rid of them any longer. From copying, they fall behind others and then they don’t want to go to school and they learn to steal. And smoking is bad for their health. At last, they become worse and worse.
It’s important and necessary for us to get rid of the bad habits in the beginning.
Going down a hill is like ______.
A. falling into bad habits B. falling into good habits C. falling into water
