题型:填空题 阅读理解. Many animal lovers would like to do more to help animals, but aren't sure where to start or feel like they just don't have the time. The good news is that there are many simple thingsyou can do to help protect animals. Think twice before you decide The decisions you make when it comes to eating meat or other animal products can goa long way toward stopping the killing of animals. Consider eating a vegetarian(素食的) diet. If you aren't ready to make this change, there are still things you can do. Do not buyanimal products from companies known to use practices that go against the law such as using drugs to increase milk production in cows. Help get the word out Getting the word out about the problems faced by animals can be as easy as putting upa notice on your car. Also, talk to your friends and family members about important issuesthat are related to animals. Give some simple advice to a friend with a new pet about theserious pet over-population problem we're facing. Turn to some books on the subject if you are not so clear about the advice you give your friend. Write a letter We've all heard the saying, " The pen is more powerful than the sword". Put this ideato the protection of animals. If a company has practices or rules that are harmful to animals, write them a letter to let them know you are angry about them, and that you won't buy their products until they make some changes. Write letters to state and local legislators(立法者)to let them know how important it is that they support legislation that protects animals. Make them know that their actions will have a great effect on your vote. Be more loving If you're considering adding a dog or a cat to your family, think about getting one from ahomeless-animal house rather than buying a pet. There are many wonderful animals just waiting for a home. By taking back an animal from there, you will be helping in the fight against pet over-population, as well as giving your money to those who are responsible fortaking care of pitiful animals. Let your actions be an example to others It may sound simple, but one of the best ways to help animals is to let your actions speakto the world. You should do the following things first by yourself: Treat all living creatures with respect. Care about your pets and look after them well.
