Grammar rule

Grammar from units 19–21

Unit	Grammar	Example
19	might / may for things that are possible	We might meet next week. They may want a new color.
20	used to for the past	I used to dream about this when I was a kid. Did you use to…?
21	who, which, that	the brand that sells jeans in every mall · a designer who makes jackets

Three things to watch: might and may take the base verb (not might meets, not might to meet); used to is for the past, with did / didn't use to (or didn't used to) in questions and negatives; and who is for people, which or that for things, with no extra he, she or it.
