The lower the temperature, the more the molecules of water vapor in the cloud cling together. Then they form droplets of water. Usually droplets form around dust or other particles in the air when the dew point is reached. If ice crystals are in the cloud, even more droplets may form.In clouds, condensation may be so rapid that millions of droplets of water are formed. As these droplets collect more molecules and therefore become heavier, their weight makes them fall to the earth. If the temperature of the air is above freezing the drops will fall as rain.When the air high above the earth is well below freezing, the moisture in the air does not form raindrops. Instead, it forms snow. Snowflakes take on many interesting shapes. They seem to be formed around a center. Snow is made up of millions of these flakes, each a bit of water vapor that in freezing temperatures was changed into a flake of snow.Snowflakes are really crystals; they are water molecules grouped in a hexagonal pattern. It is interesting to study snowflake crystals under a hand lens.Sometimes droplets of water start out as rain and change into another form on their way to the earth. The raindrops may start downward through a layer of warm air and then strike a mass of cold air, where each raindrop freezes. These frozen raindropsfall to the earth as sleet; skeet us frozen rain.Sometimes still another change may take place in drops of rain. During a thunderstorm, swift upward currents of air usually carry raindrops with them. As the air grows colder, these raindrops may form little balls of ice. In a mass of warm air, they may get a coating of moisture, which freezes as soon as they are tossed up again into a colder mass of air. Up and down they are carried, acquiring more and more layers of ice. This goes on until the balls of ice become heavy enough to fall to the earth as hailstones. If you cut a hailstone in two, you can see the layers of ice.Some scientists think that hailstones are formed in a different way. A hailstone nucleus, a tiny droplet of water that is frozen, may form high in the atmosphere. As it falls through a cloud, it meets cold water droplets and snowflakes which stick to this nucleus. The hailstone may meet many of these droplets and snowflakes before it falls from the cloud to the earth. As the droplets of water stick to the hailstone, they add a clear layer of ice. As snowflakes stick to it, they form a cloudy layer. This theory explains why clear and cloudy layers are found inside the hailstone when it is cut open.EXERCISESthe following sentences with nouns formed from the verbs given in brackets.＿of rain depends on the ＿and the ＿of tiny droplets of water vapour in the cloud.(form/condense/combine)the droplets are heavy enough to fall, ＿can take place.(precipitate)＿and ＿of water can be observed in everyday life.(evaporate/condense)＿of ice to water and water to water vapour by heating is a good ＿of the change of state of matter.(convert/illustrate)100 equal ＿are made after the ＿by＿of the boiling point of water and the melting point of ice.(divide/determine/observe)best ＿of what takes place is the ＿of good examples.(explain/provide)7.

Translate the following passage into Chinese.In some regions, particularly the dry ones ,there is water vapor in the air, but the conditions may seldom be right for this vapor to condense and fall as rain or snow. Rain, snow, hail, dew, and are known as precipitation. Even where rainfall is usually moderate, there is at times a lack of rain. A drought may lead to serious water shortages, as it did in New York City in 1949 and 1950 and again in 1963 to 1966.In the summer of 1949, New York City’s reservoirs were down to one third of what they normally held. Several billion gallons of water were being used each day. So serious was the water shortage that people were asked to have one bathless, shaveless, and washless day a week. Cars went unwashed, lawns and parks unsprinkled. Even a glass of water was not servedin restaurants unless asked for.

From the characteristics show, particularly the physical and chemical properties we can distinguish several thousand minerals, each defined by its unique set of properties. Thus all grains or crystals of quartz have just about the same qualities, regardless of the kind of rock in which they are found. Some minerals, particularly those that have a more complex mixture of atoms,vary slightly in their properties, depending on their precise composition. A mineral like garnet, for example, has a number of varieties, each with its own range of composition, such as the proportions of iron and other elements, and hence, properties. Rocks are not as uniquely defined by their properties as minerals are. Because of the immense number of ways in which the thousands of minerals can be combined, the geologist is faced with a bewildering array of rock types. The only way for us to make order out of this array is to classify like with like and to sort out by general type. The major division of rocks into igneous, sedimentary, and metamorphic is just such an aid. Within each major division there are many groups and types. Using characteristic properties, we can divide the rock kingdom into several hundred general types, each with its own more or less distinctive earmarks.Despite all of these numbers, it is remarkable how much can be done even if only a small number of the most common minerals and rocks are known. In most parts of the world a field geologist can make an accurate geologic map by knowing only a few dozen major minerals and even fewer common rock types. This simplification is possible because most of the thousands of known minerals are either rare or unusual on the one hand or subspecies or varieties on the other. Thus the geologist who can recognize garnet will do well, even though a mineral sophisticate who can distinguish the many varieties of garnet by their slightly different chemical compositions might do better. Naturally, the more we can distinguish, the more the information gleaned, and the greater the power of our theories of explanation. Than is why professional petrologists have to know a great deal about mineralogy.EXERCISESthe words in Column A with their definitions in Column B, placing the appropriate letters in the blanks: Column A Column B＿1.

The varied minerals of the earth areunderstood in terms of their architecture — the way in which their atoms are arranged to make crystal structures. The kinds of atoms and their type of chemical bonding determine not only the crystal structures but the chemical and physical properties of minerals, all of which are used for their identification. Rocks are divided into the three major groups, igneous, metamorphic, and sedimentary on the basis of origin. They are further subdivided within each group according to mineral composition and texture, which provide the data that allow us to interpret details of their origin.Lesson ThreeNEW WORDSn.火山活动n.地壳vi.破碎,断裂a.熔化的vi.延伸,延展n.,a.内部的n.火山n.行为,举止,情况n.火山学10. crystallization n.结晶(作用)11. fluid n.流体,液体vi.,vt.逃走,漏出,逸出,避免13. crack n.裂隙n.火山学家15. refer vt.,vi将…归入,认为…属于,提到a.,n.喷出的17. toothpaste n.牙膏18. extrude vt.挤出,使喷出19. eruption n.喷发,爆发20. occur vi.发生,出现21. magma n.岩浆22. dissolve vt.,vi.溶解23. fissure n.裂缝24. atmospheric a.大气25. explosively ad.爆炸(爆发)性的26. chill vt.使冷却27. atmosphere n.大气28. froth vt.,vi.,n.(使)起泡沫,泡沫29. burst vt.,vi.破裂,爆发,喷出30. bubble n.泡,泡沫31. vent n.喷口32. cone n.圆锥形(物)vi.燃烧,放光34. column n.圆柱PHRASES AND EXPRESSIONS(to) be charged with …充满着less and less 越来越少at all 完全,根本(常用在否定句中)in much the same way以大体相同的方式TEXTVOLCANISMWhen the earth’s crust fractures, molten matter may flow from the break if it extends deep enough into the interior of the earth. A volcano may form. Earth scientists have studied the behavior and composition of molten rock materials and the forms that are produced . This branch of earth science is called volcanology.Some igneous rocks are formed by crystallization of fluid matter that has escaped through deep cracks in the eart h’s crust. Volcanologists refer to these rocks as extrusive rocks, or extrusives. If a tube of toothpaste has a crack in it and you press on the tube, some of the paste is pushed out. That is, the paste has been extruded. Volcanic eruptions occur in much the same way. The magma within the earth may be heavily charged with gases and steam. These are under such great pressure that they are dissolved in the magma. If a fissure develops in a region where the magma is heavily charged with steam and otherdissolved gases, the fluid magma rises through the fissure. As it rises, the pressure on it becomes less and less. The gases and steam expand, producing a force that helps to move the molten materials to the surface of the earth.When they reach the surface of the earth, the only pressure against them is atmospheric pressure—pounds per square inch. The steam and gases now expand suddenly and explosively , producing additional great force. The molten materials, laden with rapidly expanding gas and steam, may be thrown high into the air in a wild and noisy eruption.In this kind of an eruption, the molten materials are quickly chilled by the much cooler atmosphere. They fall back to the earth as solid fragments of extrusive igneous rocks. During an explosive eruption the molten fluids may be so heavily charged with gas and steam that they froth. Bursting of the bubbles in the molten froth produces billions of tiny fragments of mineral matter, which were once part of the bubble walls. These tiny fragments may be carried upward into the atmosphere by the explosive force of the eruption. These they form great clouds of volcanic dust. Slightly larger fragments of the froth may fall back around the vent, or opening, in the crust to make a cone-shaped pile of volcanic ash.The light produced during volcanic activity is the result of the glowing of gases and molten fluids. The “smoke” of a volcano is not smoke at all, but the column of volcanic dust, steam, and other gases that are given off from the molten fluid. EXERCISESI.

Total solids，including all solids present in a water sample are determined directly by evaporating a known volume of an unfiltered water sample in a 105℃oven. Total Solids are the total of the organic and inorganic solids or the total of the suspended and dissolved solids．In an average domestic wastewater，total solids are about half organic and half inorganic，and about two-thirds in solution（dissolved）and one-third in suspension. The organic solids，which are subject to decay，constitute the main problem in wastewater treatment.Suspended solids（SS）and volatile suspended solids（VSS）are the most useful. SS and BOD（biochemical oxygen demand）are used as measures of wastewater strength and process performance. VSS can be an indicator in the organic content of raw wastes and can also provide a measure of the active microbial population in biological processes。
