Hey! You still there? Cool! Don't ask me why but it looks like I've decided to discuss strong adjectives in every class regardless of its actual level. Anyhow, I feel there are a number of reasons why this might not be irrelevant. Let's see... suppose you need to attend a funeral or express your feelings after a 50-mile hike... Can you really settle for weak words? Don't you feel you should use some serious "power words"? Here's the trick. Intermediate students should feel content if they can handle ONE strong (or extreme) adjective. C1 students ought to experience something close to insatisfaction. How do you feel after the aforementioned hike? Very tired is for wimps. Exhausted is okay for intermediate students. The C1 crowd should be ready to come up with a colorful alternative such as... knackered, shattered, dead tired, burned out, or worn out or something along those lines... Here's some simple practice:

small	tiny
big
pretty
ugly
dirty
surprising
good
bad
funny
cold
hot
clever
angry
sad
happy
strange
good-looking
disgusting
slim
tasty
