You’re on the school bus. But as soon as you turn the corner, you find yourself at the end of a very long queue. It’s another traffic jam! It is stop-start for the rest of your journey. Meanwhile, at the same time in Antarctica(南极洲), snow covers the land. A group of emperor penguins crowd together to keep warm, using stop-and-go movements to protect themselves from the winds. Can you see the connection?
Emperor penguins move like cars in traffic jams to keep warm, that’s according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow(流动) through the whole group of penguins like a “traveling wave”.
These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic “traffic jam” has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse(延时) videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction.
With temperatures usually dropping below –50, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm.
These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other. These are skills we should all learn from them when we are on the road!

In classes, your teachers will talk about topic that you are studying. (1)It will be important for you to know the information they provide 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. (2)Do this by writing abbreviations such as “km” for _______, using symbols such as “%” for ________, 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.

1.将(1)句译成中文:_________________________________________________________

2.在(2)处填入两个合适的词,使句意完整,上下文通顺:______________________

3.回答问题:Why do you need to review your notes you have taken before class?

5.在文中找出主题句:__________________________________________________________
