Must, Have to, Need to, and Don't Have to

Help the traveler complete her checklist before flying abroad. Drag the correct words into the gaps! ✈️

"OK, let me think… I [*need to*|don't have to|must to](?) renew my passport because it expires next week. I [need to|*don't have to*|must to](?) buy a travel adapter since the hotel provides them for free. And the airline website says passengers [don't have to|*must*|needs to](?) check in online at least 24 hours before departure."

The correct answer for the first blank is **need to**.

>**Need to** expresses a personal necessity — her passport is expiring, so renewing it is essential. ("Must to" is never grammatically correct.)

The correct answer for the second blank is **don't have to**.

>**Don't have to** means it is not necessary — the hotel already provides adapters, so buying one is optional.

The correct answer for the third blank is **must**.

>**Must** is used for a strong obligation set by the airline. Note: "needs to" would require the subject "he/she" — with "passengers" (plural), it would be "need to," making "needs to" grammatically wrong here.
