You can’t see any object unless light from that object gets into your eyes．Some of the things you see give off light of their own。The sun，the stars，a lighted lamp are the examples that can be seen by their own light．But most of the things you see are not giving off light of their own．They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies．The moon，for example，doesn’t give off any light of its own．It is not 1uminous．You see it because sunlight falls on it and some of the sunlight reflects on the earth．So moonlight is only second—hand sunlight．

    When you look at a book，it sends some of the light which fails on it to your eyes，and you see the book．If light could be kept out from where you’re so that there would be no light from the book to reflect．Then you couldn’t see the book even with your eyes wide open．Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time．Light reaches us from the moon，which is about 380，000 kilometres away，in only a little more than a second．

I live on the twelfth floor of a building. One afternoon I was coming home from a friend’s house. It was just after four o’clock. I got quickly into the lift and pressed Button12.

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.

As your eyes move along the line of point, they make fixations (固定) or pauses (暂停). It is important that you see several words at a fixation. It is also important that your eyes leave a group. The numbers of letters or words that you see at a fixation are called your eye span (视跨). Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.

The way in which you read always depends on (取决于) what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method is necessary. Here are four ways of reading:

(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.

(2) Rapid (快速) first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.

(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive (细致的) study of your school subjects, solving math problems or reading directions.

(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing materials that you already know well.

Some people say, “Extreme(极限的) sports are so dangerous. Why would anyone want to do them?” But the danger is what makes them so excited. Keep reading to find out the most popular ones.
