11 He is very ill. He can't eat anything. 12 Our new car is very wide. It won't get through those gates. 14 I was terrified. I couldn't move. 18 He is lazy. He won't get up early. 19 He won't get up early so he never catches the fast train. 22 He was very drunk. He couldn't answer my question. 23 It is very cold. We can't have breakfast in the garden. 24 He was extremely rash. He set off up the mountain in a thick fog. 25 We aren't very high. We can't see the summit. 26 You aren't very old. You can't understand these things. 27 He was very snobbish. He wouldn't talk to any of us. 28 The package is very thick. I can't push it through the letterbox. (Omit it.) 29 She was very mean. She never gave to charity. 30 He is very impatient. He never listens to anyone. 31 I was very tired. I couldn't walk any further. 32 It's not very dark. We can't see the stars clearly. 33 It was very hot. You could fry an egg on the pavement. 34 The oranges were very bitter. We couldn't eat them. (Omit them.) 35 Would you be very kind and turn down the radio a little? 36 He is very selfish. He wouldn't put himself out for anyone.
