WHEN & WHILE We use when and while to talk about two things that are happening at the same time. I was sleeping when the teacher finished the lesson. He was snoring while she was watching a movie. What is the difference between when and while? WHILE: Usually we use while when there are two long actions. WHEN: Usually we use when if one action is long and the other is short. We use when + past simple We use while + past continuous

Used to and didn´t use to We use 'used to' for something that happened regularly in the past but no longer happens. I used to smoke a packet a day but I stopped two years ago. Ben used to travel a lot in his job but now, since his promotion, he doesn't. I used to drive to work but now I take the bus. We also use it for something that was true but no longer is. There used to be a cinema in the town but now there isn't. She used to have really long hair but she's had it all cut off. I didn't use to like him but now I do. For negatives sentences we use didn´t use to + infinitive

Adverbs and the adjectives in English Adverbs tell us in what way someone does something. Adverbs can modify verbs (here: drive), adjectives or other adverbs.

It is easy to see how adverbs describe, or modify, verbs, since they simply explain most about the action. For example: He quickly runs She slowly walks He happily chatters
