Question
Choose the four words / phrases from Exercise 1 that you think you w ill use most often. Then decide if there are any words or phrases you don’t think you will ever use. Think about why.
Answer
There are no fixed answers here, but students may choose phrases because they include new words they want to learn (I couldn’t stop yawning; It was hilarious), or because they are phrases relevant to their lives (a twenty year old may think I didn’t crawl into bed until ... and I feel a bit rough are useful phrases), or because they just like the sound of the expression (We were all on the floor in stitches). You could point out that some expressions (It was such a disappointment; It caused a bit of a scene; It was quite awkward) might suit more mature speakers.
