There are many colors in nature. But do you know if a color has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment.
First, put two objects（物体） with the same weight into two boxes. Then cover the box. Third, wrap(裹) one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colors have different weights in a man’s mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, yellow and white.
The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for (代表)a kind of light with a certain wavelength(波长). It reaches our brain through sense organs(感觉器官).
According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors.The idea of the second paragraph is to tell us ________.
| A．a red box is heavier than a white one |
| B．a color has weight in one’s mind |
| C．white paper is lighter than red paper |
| D．you can know the weight of a color by holding it |
Why did the scientist say colors have smell?
| A．Because people can sense(感觉) the light from colors. |
| B．Because we can smell colors with our noses. |
| C．Because every color has its own sweet smell. |
| D．Because every color can give off light of the same length. |
If a person walks from a blue room to a red room, his body temperature will__________.
| A．rise | B．fall | C．stay the same | D．change now and then |
It can be known from the text that________.
| A．colors have order in weight |
| B．colors can change the weight of an object |
| C．people would stay longer in a room with red windows |
| D．colors can affect （影响）our mood （情绪）and health |
This passage is probably a __________.

The first reality TV show in the world was called Expedition Robinson and it was shown in Sweden in 1997. Half the population of the country watched the final event and a new kind of TV program was born. Two years later in Holland , the first series of Big Brother was filmed. Again, it was a great success and the final program was watched by 15 million people. Now more than 20 countries around the world have Big Brother or Expedition Robinson on their TV screens. The ordinary people who take part in the programs are known by millions of people in their own countries and reality TV has become big, big business.
For the TV producers, reality TV is a dream which comes true because many of the
programs cost nothing to make. At some point, the television viewers are asked to telephone the program to vote or to apply to take part in the show. It is the cost of these telephone calls that pays for the shows. One of the most popular shows is Pop Idol. In the show a group of attractive young people are made into pop stars. TV viewers vote for their favorite person on the show. The winner makes a record and millions of copies of the record are sold. His or her pictures are published on the covers of magazines or on the front pages of newspapers, and then, they are quickly forgotten.
But not everyone is happy about reality TV. In Portugal, two TV channels got into trouble because they showed too much of the personal lives of the people in the shows. In France, reality TV is called “rubbish TV” and the TV studios of Big Brother were attacked three times in one week. In Greece, Big Brother was described as “ against human rights and civilization”. Those who take part in the reality TV shows are usually _____.
| A．successful people | B．pop TV stars | C．attractive people | D．famous film stars |
Who would pay for the cost of the reality TV shows according to the passage?
| A．TV producers who make reality TV shows |
| B．TV actors who take part in reality TV shows. |
| C．TV viewers who telephone reality TV shows |
| D．TV companies which broadcast reality TV shows |
It can be concluded from the passage that ______.
| A．everyone is happy about reality TV. |
| B．reality TV will do well in many countries. |
| C．all the people in Europe are in favor of reality TV |
| D．reality TV will not be broadcast in any countries. |
The website “FarmersOnly.com” calls itself an online dating and friendship finder. The idea started in the mind of a man, Jerry Miller in Ohio. He wondered how farmers could meet new people who understand the life of a farmer. Jerry Miller is not a farmer but he represents a lot of farmers.
As he tells it, the idea for the site was planted when a farmer told him one day that she was recently divorced and would like to date. But someone would invite her to meet for coffee at nine o’clock at night, when she had to start her day at five the next morning.
So, in 2005, Jerry Miller launched his website. “You don’t have to be a farmer to be on FarmersOnly.com, but you do have to have the good old-fashioned traditional values of America’s Heartland.”
You also have to live in the United States or Canada to be a member of the site. Some services are free, but a full membership costs fifty dollars for a year. As of last week the site listed more than 58,000 members. Many of them are farmers in the United States. Others are students or workers involved in some way with agriculture. Jerry Miller tells us about thirty marriages in the last year have resulted from his website.
Some farmers have also found love through a group, Singles in Agriculture, which was formed as a nonprofit organization in 1986. It organizes gatherings that usually end with a dance, but is not a dating service. The purpose is to support educational and social activities that offer people a chance for friendsh

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize.
Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants（婴儿）are able to quantify substances（物质）—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food.
With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount.
“Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” vanMarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.”
“This information further refutes（驳斥）the long-held idea that babies “know nothing of the world,” vanMarle said.
“Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” vanMarle said.
In the future, vanMarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study. The quantifying ability refers to the ability to .
| A．get much knowledge of the world |
| B．identify the quantity of something |
| C．choose between different substances |
| D．obtain math-related skills |
Babies choose the larger amount of food .
| A．on personal preference | B．by saying numbers |
| C．with the help of parents | D．through their natural abilities |
We can learn from the text that .
| A．people used to think the world is known to babies |
| B．scholars disagree on baby-training programs |
| C．little research has been done on infants |
| D．some parents don’t care about their kids |
When did you last visit a shopping mall? In many places, the answer would be “last weekend”. Some people go even more often. Why? For one thing, malls offer goods and services that people need all in one place : food, clothing, things for their houses, entertainment，and even medical services. So, are mallsone of the highlights of modern civilization? Environmental activists wo
uld say “No!” They would go even further and say that consumer behavior is causing a huge environmental disaster. They cause consumers of ignorance of the side effect of their shopping—urban sprawl (城市杂乱无序拓展的地区）.
Social scientists agree that patterns of development have changed the landscape a great deal in the last half century. Prior to 1950，most people lived in towns or cities and either walked to work or took public transportation. Only very wealthy people had automobiles. Farmers lived in rural areas or isolated villages and came into town only when they needed things they couldn’t produce themselves. If you gazed at the landscape you would see towns surrounded by countryside. Then a massive change occurred.
Automobiles became affordable and people were quick to adopt them. Now ambitious workers could live in the suburbs, the areas just outside cities, which started to grow rapidly. As long as there was lots of cheap land in the suburbs, no one paid much attention to the usage of that land. Malls, fast food restaurants, cinemas, and car dealerships spread out in large, flat buildings. These one - storey buildings and their parking lot took up a great deal of space. Well - meaning farmers thought they were better off selling their land than growing crops. In ignorance, no one realized that once the land was built up in urban sprawl, the good farming land would be ruined forever. There was no way to preserve it.
Only in recent years have people come to mourn the old way of life as they have developed insight into the problems of unconditional growth. Now people realize that urban sprawl has come with serious environmental problems. The negative aspects of sprawl include air and water pollution, loss of agricultural land, traffic jams, and the death of businesses in the old town centers. Many scholars think the time has come to analyze the problems better so we can develop appropriate policies to control further sprawl. Some think the best way to do is to educate citizens about their priceless environment.What is mainly discussed in the passage?
| A．Urban sprawl | B．Weekend fun |
| C．New automobiles | D．Isolated villages |
Who do activists blame for environmental problems?

Below is some advice on how to sleep better.
1. Maintain a regular bed and wake time schedule
Go to bed at the same time every night. Choose a time when you normally feel tired, so that you don’t toss or turn. Try not to break this routine on weekends when it may be tempting to stay up late. If you want lo changeyour bedtime, help your body adjust by making the changein small daily increments, such as 15 minutes earlier or later each day. As with your bedtime, try to maintain yourregular wake-time even on weekends.
2.Fight after-dinner drowsiness（睡意）
If you find yourself getting sleepy before your bed-time, get off the couch and do something mildly stimulating to avoid falling asleep, such as washing the dishes, calling a friend, or getting clothes ready for the next day. If you give in to the drowsiness, you may wake up later in the night and have trouble getting back to sleep.
3. Keep your room dark and cool
When it’s time to sleep, make sure that your environment is dark. Even dim light —especially those from TV or computer screens —can confuse the body clock. Heavy curtains or shades can help block light from windows, or you can try an eye mask to cover your eyes. The temperature of you
r bedroom also affects sleep. A bedroom that is too hot or too cold can interfere with quality sleep.
4. Turn off your television
Many people use the television to fall asleep or relaxat the end of the day. You may even have a television inyour bedroom. However, television actually stimulates themind, rather than relaxing it. Part of this is due to content. Late night news and prime time shows frequently have disturbing, violent mat
erial. Even non-violent programming can have commercials that are jarring and loud.
5. Exercise early
Exercise helps promote restful sleep if it is done several hours before you go to bed. Exercise can help you fall asleep faster and sleep more soundly— as long asit ’s done at the right time. Try to finish exercising at least three hours before bed or work out earlier in the day.
6. Consult your doctor
Use a sleep diary and talk to your doctor. Note what type of sleep problem is affecting your sleep or if you aresleepy when you wish to be awake and alert. Try these tips and record your sleep and sleep-related activities in a sleep diary. If problems continue, discuss the sleep diary with your doctor. There may be an underlying cause and you will want to be properly diagnosed. Your doctor will help treat the problem or may refer you to a sleep specialist.To prevent yourself from sleeping too much on weekends, you should________.
