3．In modern buildings.we take a l to go up and come down．【查看更多】

When Oakland High School in California moved into a new building, the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts (專家) came to find the cause of the sickness. Finally, they discovered that the air in the building was not safe to breathe. They were surprised to find out that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards(合成板). This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化學物質). This is just one example of a modern problem that is most common in cities—indoor air pollution(污染).
People have worried about air pollution for many years, and the government has spent lots of money trying to clean up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows: Indoor air pollution is almost two to five time(倍) worse than outside pollution. So remember to open the windows and don’t stay too long in modern buildings with windows closed.
【小題1】Many students and teachers _________ after they moved into the new building.
A were very happy and excited   B. didn’t feel well    C. felt tired because of hard work
【小題2】The experts came to Oakland High School for _________.

     The oldest stone buildings in the world are the pyramids. They have stood for nearly 5000 years, and it
seems likely that they will continue to stand for thousands of years yet. The most famous of these are the
"Step" pyramid and the "Bent" pyramid.
     Some of the pyramids still look much as they must have done when they were built thousands of years
ago. Most of the damage (破壞) has been at the hands of men who were looking for treasure or, more often,
for stones to use in modern buildings. The dry climate of Egypt has helped to preserve the pyramids, and their
very shape has made them less likely to fall into ruin (廢墟). These are good reasons why they can still be
seen today, but perhaps the most important is that they were planned to last forever.
     It is most likely that plans were made for the building of the pyramids because the plans of other large
works have fortunately been preserved. But, there are no writings or pictures to show us how the Egyptians
planned or built the pyramid themselves. As a result, we are only able to guess at the methods used.
However, one thing is certain: there must have been months of careful planning before they could begin to
build. The first thing they had to do was to choose a suitable place. You may think this would have been easy
with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules
had to be followed, and certain problems had to be overcome.
     The pyramid had to be on the west side of the Nile, the side on which the sun sets. This was for religious
reasons. The pyramid also had to stand well above tho level of the river to protect it against the regular floods.
The pyramid could not be too far from the Nile, however, as the stones to build it needed to be carried in boats
down the river to the nearest point. Water transport was, of course, much easier than land transport. The
builders also had to find a rock base which was not likely to crack under the great weight of the pyramid.
Finally, the pyramid had to be near the capital, or better still, near the king's palace so that he could visit it
easily and personally check the progress being made on the final resting place for his body.

1. Most of the damage to the pyramids has been caused by _______.

A. stones
B. rivers
C. weather
D. men

2. What's the meaning of the underlined word preserve?

A. Damage.
B. Protect.
C. Build.
D. Cover.

3. What was the first thing people had to do before they could begin to build?

A. To follow the rules.
B. To draw the pictures.
C. To choose the right place.
D. To find the workers.

4. To protect a pyramid from floods they could have built it a long way from the Nile, but _______.

A. it had to be built on the west side of the river Nile where the sun sets
B. it was difficult to find a large enough rock base so far from the fiver
C. this would have been impossible because of religious reasons
D. this would have made it very difficult to transport the materials
