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 move there. Some of these insects, like mosquitoes(蚊子), carry dangerous germs. These germs cause headaches(头疼), 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(进入) your body when you touch your eyes, nose, or mouse.
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.

We know that many animals do not stay in one place．Birds, fish and other animals move from one place to another at a certain time．They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded．
When cold weather comes, many birds move to warmer places to find food．Some fishes give birth in warm water and move to cold water to feed．The most famous migration (迁移) is probably the migration of fish, which is called “salmon”．This fish is born in fresh water but it travels many miles to salt water．There it spends its life．When it is old, it returns to its birthplace in fresh water．Then it gives birth and dies．In northern Europe, there is a kind of mouse．They leave their mountain homes when they become too crowded．They move down to the low land．Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea．
Recently (近来), scientists have studied the migration of a kind of lobster (龙虾)．Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean．Nobody knows why they do this, and nobody knows where they go．So, sometimes we know why humans and animals move from one place to another, but at other times we don’t．Maybe living things just like to travel．Most animals move from one place to another at a certain time to _______．

In classroom, your teachers will talk about topics that you are studying．The information they provide will be important for you to know when you take tests．So you must be able to take good written notes from what your teachers say．
Here are the three stages(阶段) of taking notes and what you should do during each stage．
1.Before Class
Review your notes you have taken before you come to class．This will be good for remembering what was covered．Get you ready to understand new information your teacher will provide．
2.During Class
Keep your attention on what your teacher is saying and “the signal words” that tell you what your teacher is going to say and it is important to write in your notes．Examples of signal words are “The most important point…” and “Remember that…”．Be sure to include in your notes information that your teacher repeats or writes on the blackboard．Write quickly so that you can include all the important information in your notes．Do this by writing abbreviations such as med for medicine, using symbols such as % for percent, and writing short sentences．
3.After Class
Rewrite your notes to make them more complete and accurate(准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences．Use them to answer your questions．If necessary, ask your teacher for help．
