参考答案
参考解析
解析：
细节题。文章第二段第一句首先提出假设，想象在有文字记载的历史出现之前，人类在三个人烟稀少但水土肥沃的地方定居，种植植物、驯养动物。河流为驯养提供条件，农牧驯养的成功为这些地区吸引了越来越多的人和动物。第三段第一句又提到，人口向河谷和平原的迁移为这些文明的初步形成奠定了基础，由此可推断选项B（肥沃的土壤）和选项C（成功的驯养）对三大文明的形成起到了促进作用。选项D（广泛的文化交流）是人口迁移的必然结果，故也促进了三大文明的形成。而选项A（稀少的人口）只是对当时人口状况的描述，不是促成因素，故答案为A项。

DHave you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields.Components of SoilSoil is made up of a number of layers（层），each having its own distinctive colour and texture. The upper layer is known as the litter. It acts like a blanket. limiting temperature changes and reducing water loss. The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour. This layer is usually rich in nutrients，oxygen，and water. Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter. This layer is lighter in colour because of the lack of humus. Beneath the soil lies a layer of bedrock.Soil forms from the bottom up. Over time bedrock is attacked by rain, wind，frost, and snow. It is gradually broken down into smaller particles in a process called weathering. Plants begin to grow，and rotten materials enrich the topsoil. Most of the soil in Eastern Canada. for example. Was formed from weathered rock that was exposed when the ice disappeared l2,000 years ago.Water Beneath the SoilSurface water collects and flows above the ground in lakes. ponds. and rivers. Once in the soil or rock，it is called groundwater. Gravity pulls groundwater through the soil in a process called percolation（渗透）. Eventually the water reaches a layer called the water table. Under this is bedrock through which water cannot percolate.As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers. This causes a serious problem because plants require these nutrients for growth.Soil pHSoil can be acidic. neutral. or basic. The pH of the soil is determined by the nature of the rockfrom which it was formed. and by the nature of the plants that grow and rot in it.The acidity of rain and snow can lower the pH of the groundwater that enters the soil. By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils. When fossil fuels are burned. gases are released into the air and then fall back to earth as acid rain. Acid soil increases出e problem of carrying nutrients to lower soil levels. As nutrients are removed，soil is less fertile. Plants grow more slowly in acidic soil，and also become easily attacked by diseases.67. The layer of soil that provides necessary nutrients for plant growth is called.A. 1itter B. topsoil C. humus D. subsoil

问答题Practice 5 The large river best known to the ancient Greeks was the Nile of Egypt. They spoke of the river with admiration and called Egypt “the gift of the Nile”. The reason for this was, first, that the Nile brought water to a rainless desert and, second, that once a year, the river overflowed its banks, leaving, as the water went back, a new layer of fertile soil. The flood waters carry in them soil (called silt) from the upper parts of the river valley to the lower parts, and so to the sea. But as the river meets the sea, the sea acts as a barrier and forces the river to drop the silt it is carrying. There are no tides in the Mediterranean to carry the silt away, so year after year it collects at the mouth of the Nile, and the river must find its way around islands of silt to the always more distant Mediterranean. In this way, a vast area of fertile soil has been built up at the mouth of the Nile and out into the sea. The river water splits up to form small branches winding across the area. To the ancient Greeks, the mouth of the Nile looked like the drawing. Now we sometimes name things after the letters of the alphabet they resemble: a U-turn, an I-beam a T-square, an S-bend, and so on. The Greeks did the same. The triangular area of land built up at the mouth of the Nile looked like the fourth letter of the Greek alphabet delta (Δ) and so this was the name they gave it. The word is now used for all areas of land formed at the mouth of rivers which flow into tideless seas, even when they are nor triangular in shape. The Mississippi delta, for example, is not shaped at all like the Greek delta, as you will see if you look at a map.
