Unit 9: Desert Animals

A. Look at these sentences.

• Most snakes are quite harmless, but a few are poisonous.
• Most snakes lay eggs, but the rattlesnake gives birth to its young.

Now write five sentences like these using ‘most’ and the clues below.

1. (90% of) people are honest (10%) are dishonest.

4. (The majority of) films are romances, (a few) are on other topics.

B. Look at these sentences.

• Animals cannot survive for long without water.
• So desert animals have to find different ways of coping.

The first sentence says what cannot happen or be done; the second tells us what must, therefore, be done, what is necessary to do.
