Planning before buying something is a good idea. For example, you are going to buy a pet dog, you still have to consider a few things and plan them well before you welcome it in the house. 1. You will also have to train it well so that it does not misbehave in front of people. You should realize that it is a big responsibility.

2. Think about whether your pocket can manage the purchase, as well as different items for keeping the dog. If something goes wrong with the health of your pet, you will have to spend some extra money on it.

The next thing you need to consider is your home. 3. You will also have to consider the family members. If your living place is already too crowded with people, getting a dog as an additional member of the house will not be a good idea.

4. Make sure nobody is allergic (过敏的) to the fur of the dog. Also make sure that you can easily find time to train the dog. Ensure that your family is welcoming to this idea.

5. When you are bringing this best friend in your house, you must make sure everything is right for it. You should make life easier for it, as well as others who are living in your house.

A. Looking after your dog doesn’t only mean taking it for a walk or playing with it.

B. A dog is supposed to be man’s best friend.

C. Before you think about getting a dog, think about the affordability (经济承受力).

D. The training should start as soon as the dog is in your care.

E. Once the dog has learned how to sit, you may teach him to shake hands.

F. You will also have to think about any health problems related to your family.

G. A small apartment will not be fit to house a large dog.

Germs(细菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!

Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.

Warmer Weather Brings Germs

The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can movethere. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.

Under Your Skin

Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.

Fighting Germs

Your immune system(免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
