BUTTERFLY


You must notice that a butterfly has four broad, often brightly coloured wings. You may often see butterflies fluttering from flower to flower. But you have never seen them fly at night, have you? They fly only in the daytime.

The butterfly, or the butterfly stroke, is one of the five basic strokes in swimming. It is not easy to learn, but it is smooth and graceful if performed correctly. Can you do it?

When may a person get butterflies in his stomach? It may be before a job interview if he is applying for a job; it may be before a major operation if he is a patient.
