As we were talking about travelling in class here you are a series of expressions (idioms) related to the topic. Can you complete the expressions? The solutions are in the comment below.
FEET / TIME / SUITCASE / MOVE / LINE / WEATHER
1. This new job in sales means that I’ll have to live out of a …………….. for months.
2. I’ll drop you a …………………. as soon as I get there and let you know what’s going on.
3. I can’t wait to put my ………………. up and forget about work.
4. Come on! If you don’t get a ……………….. on, we’ll miss the train.
5- I’ve been feeling a bit under the …………………… all week.
6- We arrived in the nick of …………………… The show was about to start as we sat down.
This is NOT double dutch to me! 
1- live out of a suitcase (travel so much that you don’t unpack)
2- drop someone a line (write a letter)
3- put one’s feet up (relax)
4- get a move on (hurry up)
5- feel a bit under the weather (feel a bit down, depressed or unwell)
6- in the nick of time (at the last moment)
Idioms are useful to improve natural speech but as phrasal verbs, they are difficult to understand !!.
I leave one, even though it is out of the topic is related with student’s work.
“Practice Makes Perfect”
I think, this is the only one I knew.
Thanks for your contribution! I will post it in the “Sentence of the Week” category 🙂
