Bolivia has a population of three and a half million. About one tenth of the total population are white; one-fourth are mixed Indians and white; and more than half are full-blooded Indians. The government and the industries are under the control of the white people.
The Indians today live in much the same way as their ancestors. Most of them are farmers. Many work in the mines, for mining is the most important industry on Bolivia’s. Of all the mining products, tin is the most important, which makes up three-fourths of all Bolivia’s exports. The eastern slopes of the Andes, since there are very few roads there, are fertile but not highly developed. The two primary means of transportation are river boats and porters. East of the hill region is the great plains where tropical plants are grown. A serious problem for Bolivia is the transport of food from the warm regions, where it is grown, to the mountainous regions, where most of the people live.
Bolivia gained its independence from Spain about a hundred years ago. It has been slow in developing, but its rich resources promise a better future in it.

The real moment began when I stood on the platform with so many eyes fixing on me. My listeners were waiting patient. I gradually found myself back, giving my speech.

The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.
But just as in face-to-face communication, there are some rules of behavior that should be followed when on line. 1. Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread. 2.
If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 3. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
4. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you a license to correct everyone else. 5. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended (冒犯).
It is not polite to ask others personal questions such as their age, sex and marital status (婚姻地位). Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
A. It’s natural that there are some people who speak rudely or make mistakes online.
B. Repeat the process (过程) till you feel sure that you’d feel comfortable saying the words to the person’s face.
C. Everyone was new to the network once.
D. The basic rule is simple: treat others in the same way you would want to be treated.
E. When you send short messages to a person online, you must say something beautiful to hear.
F. You sho
uld either ignore the person, or use your chat software to block their messages.
G. If you do decide to tell someone about a mistake, point it out politely.
Some colors people see late at night could cause signs of clinical（临床的）depression (沮丧). That was the finding of a study that builds on earlier study findings. They show that individuals (个人) who live or work in low levels of light overnight (整夜) can develop clinical depression. Doctors use the word “clinical depression” to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide.
In the new study, American investigators designed an experiment that exposed hamsters（仓鼠）to different colors. The researchers chose hamsters because they are nocturnal（夜行的）, which means they sleep during the day and are active at night.
The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light.
After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water.
Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. “What we saw is that these animals didn’t show any sleep uneasiness (不安) at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim（微弱）red light, they did not.”
Randy Nelson notes that photosensitive（感光）cells in the eyes have little to do with eyesight. He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle.
He says there’s a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness.
1.Researchers use hamsters in the experiment because __________.
A. they are similar to humans in dealing with colors
B. they are easy to observe and study
C. they are sensitive to colors like human beings
D. they are active at night and sleep during the day
2.What sign shows that the hamsters are being depressed?
A. They drink less sugary water. B. They don’t sleep well.
C. Their eyesight becomes worse. D. Their energy level becomes low.
3.What can help people who work late at night to avoid being depressed?
A. Not being exposed to dim red light when using computers.
B. Equipping their computer screens to put it more in the reddish light.
C. Living or working in low levels of light overnight.
D. Going to see doctors of clinical depression regularly for help.
