Pets are popular. They’re good listeners, they encourage us to exercise, and they’re always on our side when we argue with others. They can bring people comfort and pleasure.
But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often — especially after you touch, feed, or clean up a pet — is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails(指甲)carefully every time you wash.
You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub (浴缸), but if you do, always disinfect (消毒) the tub immediately afterward.
Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured.
You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It’s not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw meat because it can carry germs (细菌) that cause serious illness.
And funny as it can be to see your dog or cat drinking from the toilet, don’t let pets do this. It’s bad for your pet’s health! Give them clean, fresh water to drink at all times.
Never give milk to cats. The only milk an animal should drink is from its mother. Cow’s milk is not for pets, especially for cats, as it makes them sick.
Finally, some animals aren’t pets. Don’t take in a wild or abandoned (被抛弃的) animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.

Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little equipment of yours----- it might also spread disease.
“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.
