题型：单项选择题 A1/A2型题

阅读理解。

Many people like animals, and often keep one or more of dogs and cats as pets(宠物). If you keep a dog or a cat

as a pet, you must look after it.

A grown-up(成年的)dog needs two meals a day-not more. It can eat meat, fish, rice and some other things. Dogs

like bones(骨头), but you can't give them chicken bones. Remember to give them a lot of clean water.

A dog should have a clean, dry box for sleeping(睡觉) in. Washing it once a week is good for its health. If it is ill,

take it to a vet(兽医). A healthy dog will bring you more pleasure.

Be careful when you choose(挑选)a cat. A cat has two meals a day with some meat or fish. It drinks a little milk

every day. Sometimes you can give them vegetables to eat. Don't forget that they need clean water to drink.

Take good care of your pets. They will be your good friends. Maybe they can give you some help when you are

in need.
