1. Fall back on: to have a “backup plan”; to have a plan that you can use in an emergency
E. g. You should get a college degree, so just in case you are not successful as a singer, you will have something to fall back on.
2. Fall behind: to progress more slowly than others; to be at a lower level than others
E. g. I was sick for a week, so I fell behind in class. Now I have to do extra work just to catch up.
3. Fall for: 1) to be attracted to someone; to fall in love with someone
E. g. Jane fell for Bill the first time she laid eyes on him. It was love at first sight.
2) to believe a lie; to be tricked by someone; to be gullible
E. g. I told Mike that it was snowing in the desert and he believed me! That guy falls for everything!
4. Fall into: to “end up” doing something that you hadn’t planned to do or didn’t originally want to do
E. g. Jack used to be a model student, but recently he fell into the wrong crowd and has been getting into trouble.
5. Fall off: to decrease (especially: sales, numbers, profits, etc. )
E. g. After the holiday peak season, sales usually fall off until the summer.
6. Fall through: if a plan is unsuccessful or an expectation is not met, you say it “fell through”
E. g. We were going to go camping this weekend, but our plans fell through due to the rain.
