The Mayan Indians lived in Mexico for thousands of years before the Spanish arrived in the 1500s. The Maya were an intelligent, culturally rich people whose achievements were many. They had farms, beautiful palaces, and cities with many buildings. ___ This knowledge helped them to live a better life than most people of that time, because they could use it to make their lives more comfortable and rewarding.
In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields of corn, beans, and other crops around it. To clear the land for farms, the Maya cut down trees with stone axes. They planted seeds by digging holes in the ground with pointed sticks. __ But not every Maya had to be a farmer. Some were cloth makers, builders, or priests.
The Maya built large temples to honor the Mayan gods. Skillful workers built cities around these temples. Today, many of these ancient Mayan cities and temples are still standing.
Although the cities that the Maya built were beautiful, and the people worked hard to build them, very few of the people lived in them. Usually, only the priests lived in the cities. The other people lived in small villages in the forests. They lived in small huts with no windows. The walls were made of poles covered with dried mud, and the roof was made of grass or leaves. ____.
Measuring time was important to the Maya. ____ A system was developed for measuring time accurately. Mayan priests made the system to keep track of time. They made a calendar based on their study of the sun, moon and stars. The Mayan calendar was far more accurate than the European calendars of the time.
Around the year 800, the Maya left their villages and beautiful cities, never to return. ____ They may have died from an infectious disease. They may have left because the soil could no longer grow crops. Scientists are still trying to find the lost secrets of the Maya. They are still one of our greatest mysteries.

上将该选项涂黑。选项中有一项为多余选项。
| A. Careful biological research B. The information of global warming C. Solution to the terrifying result D. Greater danger of extinction E. Examples of species in danger of extinction F. A shocking report |
The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane (沼气) and nitrous oxide. These gases, called “greenhouse gases”, prevent the heat of the sun from leaving the earth’s upper atmosphere and this makes the earth warmer.
A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.
More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plants and animals from extinction.
The scientists studied some regions of the world with a very rich biology. These regions were Europe, Australia, Central and South America and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in greater danger of extinction.
The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100 of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in this region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.

Albert Einstein offered us more than just the amazing theory of relativity and
mc². Through his persistence in his discoveries in science, Einstein shined a light on how each of us can do the impossible by working hard, experiencing failure, and valuing people.
● Simplify Your Work
“ If you can’t explain it to a six years old, you don’t understand it yourself.” --Albert Einstein
The more complicated you have to make something seem, the more you do not understand the inner workings of it. Did they make even the most complicated topics full of vocabulary that you did not understand or did they make it easier to understand by simplifying?
● Live in the Present
“ I never think of the future - it comes soon enough.” --Albert Einstein
You can try to get yourself worried about the future and make plans that may not work out according to plans. What matters most is living now, today. Do your best right now and do not worry about tomorrow.
● Work Towards the Impossible
“Only those who attempt the absurd can achieve the impossible” --Albert Einstein
If it seems ridiculous to others and you are willing to take the risk, then you are able to achieve the impossible. You complete what was once an obstacle.
● Value People
“Life isn’t worth living; unless it is lived for someone else.” --Albert Einstein
If you put people first, they will value you and consider you a person who genuinely cares about others. Show them that you value them. Thank them and send compliments their way. It will not only make their day better, but they will appreciate it and remember what you have done for them.

In the 60s, people asked about your astrological (about star) sign. In the 90s, they want to know your website. Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity.
Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.
While web pages vary greatly in their design and content, most use a traditional magazine layout(版面设计). At the top of the page is a banner(横幅)GRAPHIC. Next comes a greeting and short description of the site. Pictures, text, and links to other websites follow. Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site.
While there are no rules you have to follow, there are a few things to keep in mind: If you want too much at the beginning, you may never get the site off the ground. You can always add to your site.
Less is better. Most people don’t like to read a lot of long texts online.
Smaller is better. Since it can take a long time to download large files, keep the file sizes small.
Have the rights. Don’t put any material on your site unless you are sure you can do it legally. Always remember to get the permission from the writer first.
Now it’s time to roll up your sleeves and start building.
| A．Start simply. |
| B．Break it into small pieces. |
| C．Draw a rough layout on a sheet of paper. |
| D．Many websites are considered very interesting. |
E. Before you start building your site, do some planning.
F. Think of your home page as the starting point of your website.
G. These days, having a web address is almost as important as a street address.
