Early people had very little effect on the environment. They lived in caves in very small ‘clan’groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which means that they did not stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖) before the clan returned for the next season.
As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually , people tamed(驯养) wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so they began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also gave people more free time. So art, dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.

It was unusually quiet in the emergency room on December 25.
I was nurse on duty that day. I didn’t think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children.
“Are you all sick?” I asked suspiciously.
“Yes,” she said weakly and lowered her head.
But when it came to descriptions of their presenting problems, things got a little vague. Two of the children had headaches, but the headaches weren’t accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it.
Something was wrong, but I didn’t say anything but explained that it might be a little while before a doctor saw her. She responded, “Take your time; it’s warm here.”
On a hunch (出于直觉), I checked the chart after the admitting clerk had finished registering the family. No address---they were homeless. The waiting room was warm.
I looked out at the family huddled by the Christmas tree. The little one was pointing at the television and exclaiming something to her mother. The oldest one was looking at an ornament on the Christmas tree.
I went back to the nurses’ station and mentioned we had a homeless family in the waiting room. The nurses, grumbling about working Christmas, turned to compassion for a family just trying to get warm on Christmas. The team went into action, much as we do when there’s a medical emergency. But this one was a Christmas emergency.
We were all offered a free meal in the hospital cafeteria on Christmas Day, so we claimed that meal and prepared a banquet for our Christmas guests. We needed presents. We put together oranges and apples in a basket. We collected from different departments candies, crayons and other things available that could be presents. As seriously as we met the physical needs of the patients that came to us that day, our team worked to meet the needs, and exceed the expectations, of a family who just wanted to be warm on Christmas Day.
Later, as the family walked to the door to leave, the four year old came running back, gave me a hug and whispered, “Thanks for being our angels today.”Which of the following would be the best title of the passage?
| A．Working Christmas Day |
| B．Christmas Day is Coming |
| C．A Happy Family |
| D．A Pale Woman and Four Small Children |

By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat?
To solve the problem, we should have to double our food production. We can also develop a diet of algae（海藻）, insects and meat grown in laboratories.
Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars.
Man-made meat looks like meat, feels like meat and it is meat, although it’s never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land.
China has developed “green super rice”, a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding（作物育种）techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years.
Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein（蛋白质）, low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.In order to exist in the future, people have to _______.
| A．move to other planets |
| B．produce rain in laboratories |
| C．build new laboratories for food research |
| D．increase the food production or look for other food sources |
From the second paragraph we know that _______
| A．algae have a strong life force |
| B．few people eat algae now |
| C．algae have few values for human beings |
| D．algae can pollute our environment |
Green super rice _______
| A．has to be watered with salty water |
| B．can grow even in a bad environment |
| C．includes no more than 250 rice kinds |
| D．was developed with new technologies |
What can we learn from the passage?
| A．Green super rice is delicious but high in price. |
| B．In Asia about 100 million people may be faced with food shortages. |
| C．Man-made meat doesn’t look like meat but has the same taste as real meat. |
| D．One of the reasons why many people begin to eat insects is their rich food value. |
Our environment isn’t as green and beautiful as it should be. There are steel monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth.
You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “ accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.
At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps（水龙头）are not leaky（泄露的），which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs.
Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.
Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.
With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.The underlined word “scrimping” in the third paragraph can be replaced by _____.
| A．saving | B．cleaning | C．cooking | D．drinking |
From the fifth paragraph, we can know that ________.
| A．protecting the environment begins with small chores |
| B．protecting the environment should start from childhood. |
| C．wonderful life comes from environmental protection |
| D．protecting the environment benefits the country and the people |
Which of the following isn’t true?
| A．The more people do their part, the greener the environment will be. |
| B．Selling what you don’t want any more is a kind of recycling. |
| C．To protect the environment may help you save some money. |
| D．Your bad habits for the environment are a valuable contribution. |
Which of the following can be the best title for this passage?
| A．The Use of Garbage Dustbin |
| B．How to Save Water and Electricity |
| C．How to Save the Environment |

A famous Renoir had been stolen from a museum. Detective Earl Blackman was to work on the case.
Everyone was in the dark before an art professor came to point out the false picture. So the museum even didn’t know when the picture had been stolen. Thousands of people came to visit the museum every day. After long work, some art students were focused on.
The five students who had made copies of the Renoir during the last six months were asked to bring their copies to the museum. The fifth student said she had sold her copy, which was later proved to be the one in the museum. She, however, could only remember the buyer was a man with the little finger on his left hand missing.
Blackman went back and stayed in his office looking at all the pictures of known thieves. No success.
The next afternoon, at about closing time, Blackman went to the museum to ask if the cleaning men were in the museum after everyone else had left. The director told him they had no cleaning man but six cleaning women.
As the detective left the director’s office, he saw five cleaning women. He stopped one and asked about her work. Then came the sixth cleaning woman. She was dressed just like the other women except the gloves on her hands which made her different. Blackman watched her for some time. When she came near, Blackman caught her.
