4．either  make  signs them best provide who sure prevents others

If you visit the animal shelter （收容所） in Salinas，California，you'll see huge signs that have a picture of a dog and a cat on them．These （71）signsare put in front of the shelter to catch people's attention．The signs （72）makepeople interested in the shelter and encouraged them to visit it and maybe
even take a cat or a dog into their homes．
Each year，the Salinas shelter accepts thousands of dogs and cats．The animals are （73）either lost ones or are left by people who can't take care of （74）them．Of all the animals，some of them are taken into new homes．Some （75）others are moved to other shelters．And，unluckily，some cannot be saved because they are too sick or are thought to be dangerous．
Animal shelters （76）provide food，medicine，and safe places for animals．But they are not the（77）best  homes．The animals stay in small cages （笼子）．The people （78）who work at shelters do their best to care for the animals，but the animals do not always get the attention or exercise they need．
To prevent a nimals from becoming homeless，pet owners should take good care of their pets．Most pet doctors also suggest people make （79）sure their pets have a special surgery （ 外科手术）．It （80）prevents animals from having more babies．And that reduces（减少）the number of homeless animals．
