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 move there. 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.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

A.kill germs | B.carry germs | C.protect germs | D.love germs |

小题1:D 根据Fighting Germs这一段可知“细菌进入身体,我们的免疫系统会发现并消灭细菌”
小题1:C 根据倒数第二段最后一句Antibodies help your body find and stop germs.“抗体帮我们发现并阻止细菌”可知答案为C

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

These are the steps to follow when you are reading something difficult:
1. Start to read normally until you run into a sentence that doesn’t make sense to you.
2. When a sentence doesn’t make sense, go back and read it again more slowly.
3. Look for any word you don’t know in the sentence. Try to understand their meanings using word parts and context clues(上下文线索). If necessary, look them up in the dictionary.
4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do not read very much farther ahead until you understand what is being said.
5. Finally, read the sentence again. Try to put it into simpler words.
6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage once more at a usual speed. This helps you to put all ides together.
The stops sound a lot harder than they are. It is really just the normal way good readers understand anything that is difficult to read. After you have done the best you can this way, you should always feel free to ask for help from your teacher, if you have one.
