Buildings Full of Light
Roman buildings were popular only as long as builders were limited in how tall they could make a building. They had not learned how to support the walls of a tall building.
About 1140, a new kind of building appeared in Europe. These new buildings were churches, or cathedrals, and they were seen first in France. Today, these cathedrals are called Gothic(哥特式的) buildings. Their pointed arches(拱门) rise toward the sky. They look very different from the Roman buildings that have low arches and thick walls. Unlike the dark Pantheon(万神殿) all these buildings are full of light.
Builders of the Gothic cathedrals found a new way to build strong walls and tall arches. They built supports outside the building. These supports, called “flying buttress(扶壁) ”, helped hold the walls. Buttress made it possible to build high buildings.
One end of a narrow beam(栋梁), or the flying buttress, was planted away from the wall. The other end was placed high up on the wall. The flying buttress acted like a crutch(支柱).
Since these buildings had many windows, artists made pictures in them by using small pieces of colored glass held together with lead(铅). Sunlight shines through the glass and made soft splashes of color inside the churches. Stained(染色的) glass windows and flying buttresses were part of every Gothic cathedral.

开心蛙口算题卡系列答案Years ago a farmer owned land along the Atlantic. He constantly advertised for hired hands. Most people were not willing to work on farms along the Atlantic because they worried about the terrible storms that destroy buildings and crops. The farmer received a steady stream of refusals at the interview for a farmhand
Finally, a short, thin man approached the farmer. “Are you a good farmhand?” the farmer asked him.
“Well, I can sleep when the wind blows. ” answered the little man.
Although puzzled by this answer ，the farmer, desperate for help, hired him. The little man worked well around the farm ，busy from dawn to dusk, and the farmer felt satisfied with the man's work.

Planting trees around poultry farms can improve air and water quality -- and relations with neighbors. Research has shown that just three rows of trees near poultry houses can reduce the release of dust and ammonia(氨). They can also reduce the strong smell of ammonia gas.
The trees take dust, ammonia and odors in their leaves. They also provide shade from the sun, so they reduce cooling costs in summer. And they act as a windbreak, so they reduce heating costs in winter. Trees can also improve water quality around farms by removing pollutions from soil and groundwater.
Several years ago, people were objecting to the odor of poultry farms on the Delmarva Peninsula in the eastern United State s. Delmarva is where the states of Delaware, Maryland and Virginia come together. Two thousand farms there can each house an average of seventy-five thousand chickens.
Traditionally the farms used windows to provide fresh air in the chicken houses. Farmers rarely planted trees or tall crops around the buildings, so there would be no barrier to the airflow. But then farms began to use new ventilation systems. Instead of windows, the new systems used tunnel fans to circulate air. The fans directed airflow from the poultry houses toward the homes of neighbors.
Researchers began dealing with the problem in two thousand. They found that over a period of six years, planting three rows of trees reduced total dust and ammonia by more than half. And they found that smells were reduced by eighteen percent.
Farmers may think trees will take too long to grow and be effective. But some trees can grow quickly. At least one-third of the Delmarva farms have planted trees, technically known as vegetative environmental buffers. The idea offers a way to cut pollution, save money and energy, and make the neighbors happy.

| A．three rows of trees are really good to the environment |
| B．researches began to realize the problem in 2000 |
| C．most farmers show interest in planting trees |
| D．the trees growing quickly can be cut off in a few years |
