Read the text about appearance.

What is an appearance? Appearance is human look. People can look very differently: be skinny or plump, tall or short, well-built or fit, bald or curly. People have wrinkles, moles and freckles on their faces.

Hair can be very different: some people prefer cutting it short, some let it grow long. Some men shave their heads and are bold. Some people dye their hair, and some like its natural colour — blonde, brown, red or black. Often when we talk about senior people, we call their hair grey or 'salt and pepper' hair.

There is a proverb that says that the eyes are windows of the soul. Probably it's true. People's eyes can be brown, blue, black or green. Some people have different-coloured eyes, for example, one blue and one brown. It's called heterochromia.

Some people are pale and some are dark-skinned. If you are very pale, be careful in summer — you can get sunburned in no time.

We call the manner of walking the walk or pace. Some people limp, some shuffle, some stumble.

1. People have

2. Some people have
