Taking good notes is a time-saving skill that will help you to become

a better student in several ways 1.Second, your notes are excellent materials to refer to when you are studying for a test. Third, note-taking offers variety to your study time and helps you to hold your interest.

　　You will want to take notes during classroom discussions and while

reading a textbook or doing research for a report. 2.Whenever or however you take notes, keep in mind that note-taking is a selective process . 3.

　　The following methods may work best for you.

　　●Read the text quickly to find the main facts and ideas in it.

　　●Carefully read the text and watch for words that can show main points  and supporting facts.

　　● Write your notes in your own words.

　　 ●4.

　　 ● Note any questions or ideas you may have about what was said or written.

　　As you take notes, you may want to use your own shorthand(速记). When you do, be sure that you understand your symbols and that you use them

all the time. 5.

C. You must write your notes on separate paper.

D. Otherwise, you may not be able to read your notes later.

E. you will also want to develop your own method for taking notes.

F. That means you must first decide what is important enough to include  in your notes. 

G. First, the simple act of writing something down makes it easier for you to understand and remember it.

It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin.

　　Al Herpin, it was said, never slept. He was 90 years old when doctors came to his home in New Jersey. They expected to find out that he needed sleep of some kind. But they were surprised. Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one.

　　The closest that Herpin came to resting was to sit in a rocking chair(摇椅) and read some news papers. The doctors were puzzled by this strange continuous sleeplessness. Herpin offered the only probable explanation of his condition. He remembered some talk about his mother having been injured several days before he was born.

The point of this story is that _______.

　A. We needn't feel surprised to find someone who doesn't sleep

　B. one person was found who actually didn't need any sleep

C. everyone needs some rest to stay alive

　D. not sleeping may help one to live longer

After watching him closely, the doctors believed that Al Herpin _______.

　A. needed some kind of sleep   　B. slept while one was watching

　C. needed no sleep at all  　　　D. nearly slept in a rocking chair

One suggested explanation of Herpin's sleeplessness was _______.

　A. his old age  　　　

B. his not having a bed

　C. his magnificent physical condition

　D. his mother's injury while carrying him

The writer of the story obviously thinks that Al Herpin's sleeplessness ___.

　A. could be cured  　　　B. could be explained

　C. was healthful   　　　D. was uncommon

A Battery’s Worst Nightmare(噩梦)
Portable electronics that can be carried about easily are only as good as their batteries and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life!When the fuel runs out in your laptop or mobile phone, you just fill up and go.
The engine, about the size of a ten-cent coin, starts with a combustion chamber (燃烧室) that burns hydrogen (氢). Its tiny parts are etched onto silicon wafers (硅片) in the same manner that computer parts are imprinted onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.
But the devil in all this nice detail is efficiency(效率). Tiny engine parts don’t always behave like their scaled-up parts of the first engine. Something between the parts can slow down the work, according to Columbia University professor Luc Frechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.
The scientists’ goal is to create an engine that will operate 10 times better than batteries do. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t available until at least the end of the next ten years.
