Grass is, of course a plant which grows in the field; a plant which some kinds of animals like to eat. When there has been plenty of 1 , the grass is green. When the weather has been dry, the grass is brown. Animals like to eat grass when it is 2 and fresh. And if the grass in one place is greener than the rest, animals 3 to eat that grass. An animal in a field may look over the fence( 篱笆 ) into the next field , where perhaps there are no animals and grass in the field 4 greener. But if the animal could get into the field, it would find that the grass is really the same. It just seems better from a distance( 远处 ). So that's the 5 of the expression “The grass is greener on the other side of the fence.” We sometimes only say “The grass is 6 greener on the other side.” We use the expression to describe the situation — someone looks at distant things and feels they are better than the things around him. But 7 he could go to the distant place, he would find that life there is just as difficult. So don't always think that other people have a better situation. Just be 8 with what you have had. Enjoy and value it!
