Conditionals?

1. You mustn't use your mobile phone until the plane lands/has landed.

2. Many people have problems sleeping if they drink/are drinking coffee after midday.

3. I want to spend a year travelling when I finish/ I have finished university.

Can I use both options in each of the sentences?

Thank you!

anonymous 1. You mustn't use your mobile phone until the plane lands/has landed. I would recommend "has landed", since, strictly speaking, this is clearer that you must wait until landing is completed, rather than being able to use your phone while the plane is landing.

  • However, common sense tells us anyway that the former meaning is probably intended, so in practice "lands" is likely to be understood the same.
