Some cities grow very large because of two important reasons. First, there may be importan

t natural resources like wood, gas, oil, rivers or harbors near or in the city. Natural resources like wood or oil can be brought to the city and made into products to sell. Other resources, like rivers or harbors help to send the city's products to other places to be sold. Second, the city may be located in a place where roads and rivers come together. This makes these cities good places to buy and sell goods.

Houston is a city that grew large because it has two important natural resources. They are oil and a good harbor. The oil can be brought to Houston, made into different products, and shipped out of the harbor to other parts of the world.

Chicago is a city that grew very large because of its location at a place where roads, railways, and airways meet. In Chicago, goods can be brought together from all over the country and bought and sold. Then the goods can be loaded into trucks, trains or planes and sent to wherever they are needed. Because of Chicago's location, many people live and work there.

Some cities grow large because of ______.

A．natural resources

B．convenient traffic

C．population growth

D．A and B

Insects live in bushes and grass and trees, in fields and houses and in the ground. Some e

ven live on other animals.

Did you know that there are more insects in the world than any other kind of animal？ They fly and hop and crawl and dig. Some insects, the ants, build hills and cities of their own. Insects called silk worms spin silk. Bees make honey. And crickets(蟋蟀) make music with their feet.

Lots of insects grow up in a curious way. When they are little, they look like tiny worms, and most of their lives are spent in just growing. Mosquitoes(蚊子) start this way, and so do beetles(甲虫) and flies, ants and bees. Some caterpillars (毛虫) grow into butterflies. Other wormlike wriggling (蠕动) things become moths (蛾). So all insects do not look the same. Worms in fruit are insects. So are caterpillars and potato beetles, flies and moths.

The things that some insects do are helpful to people. They spin silk and make honey and help the flowers to make seeds. Some insects are pests. They bite and sting (叮) and eat our plants and clothes, food and even furniture. Insects are everywhere.

Insects live ______.

A．in bushes

B．in the ground

C．on some animals

D．all of the above

第4题

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. The Mayan people knew a lot about nature and the world around them. 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. Knowledge about tools and farming, for instance, made their work easier and more productive.

In ancient Mexico there were many clearings in the forest. In each clearing was a village with fields of different crops around it. The Maya cut down trees with stone axes and planted seeds by digging holes in the ground with pointed sticks. A farmer was able to grow crops that produced food for several people. But not every Maya had to be a farmer. Some were cloth makers, builders, or priests.

The Maya believed in many gods. The people built large temples to honor their gods. Skillful workers built cities around these temples. It was difficult to construct these cities, because they had no horses to carry the heavy stone needed. Workers had to carry the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing.

Measuring time was important to the Maya, so they developed a system for measuring it accurately. Farmers needed to know when to plant and harvest their crops. Mayan priests made a system to keep track of time. They wrote numbers as dots (...) and bars (- ). A dot was one and a bar was five.

The Mayan priests studied planets. They made a calendar from what they learned. The year was divided into. 18 months of 20 days each with five days left over. 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. No one knows why. They may have died from an infectious disease. They may have left because the soil could no longer grow crops. Archaeologists are still trying to find the lost secrets of the Maya. They are still one of our greatest mysteries.

This article may be taken from ______.

A．a magazine

B．a literature book

C．an art book

D．a historical book
