Even if you don‘t live in America, you can also show your love to ani mals. How? First think about how animals make your life richer (更丰富). If you have a pet, take more time this week to play with it. Remember to give it nice food. If you don‘t have a pet, be kind to animals around you. For example, if you see a street dog, don‘t kick it. Just leave it alone, or make friends with it. If others around you do bad things to animals, try to stop them. As people, we must protect (保护) animals because they can‘t speak for themselves.( )38.
