The oldest stone buildings in the world are the pyramids. 1 .There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids.The most famous of these are the “step” pyramid and “ Bent ”pyramid.
Some of the pyramids still look much the same as they must have done when they were built thousands of years ago.Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings. 2 .These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last.
Forever, 3 .However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. 4 .Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly clear picture of them.
One thing is certain:there must have been months of careful planning before they could begin to build. 5 .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.
A.T he dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.
B.It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved.
C.The first thing they had to do was to choose a suitable place.
D.Consequently, we are only able to guess at the methods used.
E.Many people were killed while building the pyramids.
F.They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.
G.It takes workers twenty years to build the Pyramids.

Soil conservation(保护)efforts protect soil from wind and water that can blow or wash it away.[1]_________ One important form of soil conservation is the use of windbreaks.Windbreaks stop the wind from blowing soil away.They also keep the wind from destroying or damaging crops.Windbreaks are barriers formed by trees and other plants with many leaves.[2]_________ Windbreaks are effective when a wall of trees and other plants blocks the wind.The windbreaks should also limit violent motions of the wind to those areas closest to the windbreak.
[3]_________ If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground.These motions cause the soil to lift up into the air where it will be blown away.[4]_________ An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreak.There should be at least two lines in each windbreak.One line should be large trees.The second line, right next to it, can be formed from shorter trees and other plants with leaves.Windbreaks not only protect land and crops from the wind.They can also provide wood products.[5]_________
a.Windbreaks seem to work best when they allow a little wind to pass through.
b.Good soil produces food crops for both humans and animals.
c.For the long term, trees will be planted throughout the area to act as windbreaks which will provide adequate protection.
d.Farmers plant windbreaks in lines around their fields.They are very important when grains such as wheat are grown.
e.Plantations are also sometimes known as “man made forests” or “tree farms”.Environmental Plantations may be established for watershed or soil protection.These are established for erosion control, landslide stabilization and windbreaks reduce carbon di oxide and increase oxygen levels in atmosphere.
f.These include wood for fuel and longer pieces for making fences.Locally grown trees and plants are best for windbreaks.
g.For this reason, a windbreak is best if it has only 60 to 80 per cent of the trees and plants needed to make a solid line.

CATV is a short way of saying “community antenna(社区天线)television”.But “cable television” is the term most people use.[1]________
Television signals do not follow the curve(曲线)of the earth.[2]________ If you live only a few miles from a station, you may not get any picture at all.
[3]________ A community antenna was usually placed on a hill, a mountain, or on a high tower.Theantenna picked up TV signals and fed them into a small local station.From the station, thick wires called cables ran out to nearby homes.Each person using the cable paid a monthly charge.
CATV worked well, and soon new uses were found for it.Local stations could feed programs into empty channels that were not in use.[4]________
Today, cable television has moved into cities.It brings in extra programs that city viewers with regular antennas cannot see.[5]________
A.They travel in straight lines in all directions.Signals from a TV station move toward the horizon(地平线)and then go into space.
B.The wide use of CATV is due to the widespread of the TV set in almost every family.
C.Cable television allows viewers to receive TV programs that they cannot pick up with their regular antennas.
D.People along the cable could have local news, weather reports, and farm and school news at no extra charge.
E.CATV began in 1948.People in places far from TV stations shared the cost of putting up high antennas.
F.It is also used in many classrooms throughout the country.
G.Therefore, they could watch TV with extra charge.
