题目内容

You can not 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 examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.

When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.

Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.

1.You can see the book because_______.

A．your eyes are close to it	B．it reflects some of the sunlight
C．it has light of its own	D．your eyesight can get to it

2.The underlined word “luminous” means_______.

A．visible

B．all colors

C．giving off light

D．sunlight

3.________ have light of their own.

A．The sun and the moon	B．The stars and the earth
C．The sun and the stars	D．The moon and the earth

4.Which of the following is true?

A．All the things you can see give off light.

B．Light from the book is much shorter than that from the moon.

C．The moment you open your eyes the light from the book travels to your eyes.

D．Light travels so fast that there is no time for you to read.

Remembering your dreams will require some efforts on your part. But what your dreams can offer and tell you about yourself will be well worth it . Here are some tips to help recall your dreams:

The internet will open up new vistas (前景), create the global village —you can make new friends all around the world .That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationships with more than a limited number of people. No matter how hard the internet tries to put you in communication, its best efforts will be defeated human mind.
The problem is twofold（双重的）.First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest（投入）in them. We invest a lot in a small number of people and then distribution what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline（减弱）until eventually it dies into “someone I once knew”.
This is not, of course, to say that the internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see then, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.
