light of a second unit, elementary wisdom.
1. shadow producing conditions: (light, transparent objects, shade).
2. the direction of the shadow of the sun as the object (the sun direction) is changed, the shadow and the sun is always in the direction (the opposite).
3. the sun shadow of the object (width) of the change is with the sun in the sky (position) change, the position of the sun (tall ) shadow of the (short), the situation of the sun (cheap) the shadow of the (long).
4. It has long been understood by the sun (variation of the shadow of the object) to determine the time. the ancient people used to use (at movie observation instrument) time, such as (sundial).
5. just to (straight line) in the form of communication. is the circulation velocity of light per second (300,000) km.
6. reflected light is forward the (straightforward) transportation.
7. Many sources in the hair (light) are made at the same time (heat). the sun has brought us (the light) at the same time send us (lukewarm).
8. light intensity on the temperature (high), (feeble light) temperature on the (low).
9. it was base (concave) and (convex) can light up together to form a lusty light and high temperature,
10. (sun) is the largest source of light and heat the world. The sun's outer temperature of approximately C (6 thousand degrees), the interior temperature of approximately C (2 million degrees). Earth's solar stamina received, only accounts fhardly everlar radiation vigor (twenty- one million).
11. The color and heat-absorbing aptitude is related to dark heat-absorbing objects, the object than the light (fast).
12. objects, sun angle and endothermic relative objects endothermic than the perpendicular slope with the sun (hasty).
13. solar water heater is a (solar thermal converter), with (energy), (green), (security) conveniences.
Second, the interpretation of the concept of .
1. source: such as light emitting object is called its source.
2. to make sure an object is light, first light in their own prelude, and is creature be called light-emitting objects such light source.
3. Projection: obtain the thing from another sides, the shadow of exposure is phoned projection.
4. the reflection of light: light kick the mirror changes the direction of propagation, is reflected behind, a phenomenon called the reflection of light , also called reflective.
three, case in point.
1 life use of the principles of light reflection.
A: ① ② car mirror with the amount of physicians mirror ③ ④ light shade on the wall of the classroom ⑤ telescope painted white.
3, concave and convex principles of the application.
A: convex lens magnifying cup ① ② periscope; concave mirror: ancient copper mirror with a concave make launch, the use of concave mirror made of the principle solar cookers, the Olympic flame blaze is the use of concave mirror made of ... ...
four short response.
1, the shadow What are the specifics?
A: ① the situation of the shadow will be with the light source, the change of instruction change. ② The size of the shadow and block light objects and the distance between the light source, is, a large shadow from the small, large shadow from the small. ③ light source the shadow of the object shape and the shape of the side.
2 how is the eclipse of? Why shadow is forever in the backlight side?
A: light travels in straight lines, the light propagates via the vague objects if they are in the light of objects behind it will not depart a place dark areas, the formation of a shadow dark areas.
third unit and change the Earth's surface topography and terrain functions
: Mountain: quite high, crooked down, several overlapping peaks; Hill: The ups and downs, than the slope slow, low hills formed by the perennial; plateau: an area of vast, open terrain, to remove the soak slopes circling the border; plain: wide flat outlook, rolling small; basin: four weeks was quite high, middle low, flat; Earth more on the sea, land less, more mountains of western China, east and more plain.
2. earthquakes and volcanoes are reasoned by motion of the Earth's internal. Earth's interior can be divided into crust, mantle, gist of three parts. most of the earthquake occurred in the crust. volcano activities narrated to the mantle and crust movement.
3. collision of two continental plates fashioned the magnificent Himalayas. continental plates collide, separate, pan, resulting in magnificent changes in the surface. If the formation of mountains , Highlands, Rift Valley and trenches and so on. also trigger volcanic outbreaks, earthquakes, tsunamis, etc..
4. two plates of the Great Rift Valley is formed by extensional fault ravine. topography caused by motion of the Earth's interior changes.
5. rocks underlying causes of changes in the role of cold and heat; the role of water; the role of plants; animal role. due to water, air, temperature, or the role of animals and plants, rock trampling, a phenomenon called weathering . gravel and sand is formed by rock weathering.
6. According to the mote size of soil particles can be classified: the biggest is the pebble, emulated by sand, is smaller than the sand silt,does the melody itself ought be brings the sensory judgments lacking you, the smallest soil particles is clay.
7 . soil humus and salt is essential for plant growth nutrients. humus is decomposed plants and animals on black material, salt is liquefied minerals in water.
8. soil is sand, gravel, clay, humus , water and air medleys.
9. Soil is the planet's maximum valuable resource. in each cubic meter of soil, billions of alive creatures. soil to provide them with edible and living space too provide shelter and food for people sources of matter. and always alive creatures in the soil and garbage residues can enrich the soil humus. beast and plant roots can loosen the soil, climate and water to build space.
10. raindrops fall to the ground is the beginning of soil erosion. clay and sand bathed away by rain lighter lightly.
11. of land the size of the slope, with or without plant cover, rainfall will influence the size of the degree of soil erosion.
12. As the character of water erosion on the land surface will be the formation of numerous flows and gullies. streams come attach they will convert a huge river. riverbed covered with large stones upstream, midstream mattress piled Many of the pebbles, river bed full of yarn.
13. nature, every time the phenomenon of erosion and deposition have occurred. erosion makes some of the ground where soil erosion processes, and deposition has filled a number of low-lying areas , erosion and deposition form a different landforms on the planet.
14., water, air, glaciers, and gravity waves will erode the land. erosion of the soil erosion in some places, changing the topography, when the human production and life also had a colossal shock. in order to protect their homes, people try to lessen erosion.
motion and force the fourth unit
1, thousands of annuals antecedent, man invented the automobile. hove the cable cord automobile is the car forward
2, there is a downward force on the object, which is gravity. apple on the tree to fall, discard up the pellet eventually falling to the ground, these are as by their own gravity
3, the rubber band ring linking one end fixed on the border and the other end firm to the axle, turn the wheel, so that rubber band wound approximately the axle, loosen the hand wheel will corner.
4, when the rubber band is stretched to generate power.

1. shadow producing conditions: (light, transparent objects, shade).
2. the direction of the shadow of the sun as the object (the sun direction) is changed, the shadow and the sun is always in the direction (the opposite).
3. the sun shadow of the object (width) of the change is with the sun in the sky (position) change, the position of the sun (tall ) shadow of the (short), the situation of the sun (cheap) the shadow of the (long).
4. It has long been understood by the sun (variation of the shadow of the object) to determine the time. the ancient people used to use (at movie observation instrument) time, such as (sundial).
5. just to (straight line) in the form of communication. is the circulation velocity of light per second (300,000) km.
6. reflected light is forward the (straightforward) transportation.
7. Many sources in the hair (light) are made at the same time (heat). the sun has brought us (the light) at the same time send us (lukewarm).
8. light intensity on the temperature (high), (feeble light) temperature on the (low).
9. it was base (concave) and (convex) can light up together to form a lusty light and high temperature,
10. (sun) is the largest source of light and heat the world. The sun's outer temperature of approximately C (6 thousand degrees), the interior temperature of approximately C (2 million degrees). Earth's solar stamina received, only accounts fhardly everlar radiation vigor (twenty- one million).
11. The color and heat-absorbing aptitude is related to dark heat-absorbing objects, the object than the light (fast).
12. objects, sun angle and endothermic relative objects endothermic than the perpendicular slope with the sun (hasty).
13. solar water heater is a (solar thermal converter), with (energy), (green), (security) conveniences.
Second, the interpretation of the concept of .
1. source: such as light emitting object is called its source.
2. to make sure an object is light, first light in their own prelude, and is creature be called light-emitting objects such light source.
3. Projection: obtain the thing from another sides, the shadow of exposure is phoned projection.
4. the reflection of light: light kick the mirror changes the direction of propagation, is reflected behind, a phenomenon called the reflection of light , also called reflective.

process of this usage shown in Figure 1, the raw water through the water with a grid of wells afterward the removal of large drifting through the water pump upgrade, and then grind through 3 or water down the sink later the water into the aeration folk ditch aerobic biological percolate. wrinkle aerobic biological filter according to the another packing gravel segment is divided into two segments and the carbon leftovers, followed by purification factory bed and ecological ditch, the water tank were explicit, the last efflux. < br> ditch the advantages of biological filter:
① ditch biological filter at chamber temperature, the urban landscape treatment of contaminated water, can control the water repugnant color, smell, savor and other sensory features, and ammonia are certain removal.
② biological filter trench generally cheap biomass, merely the root zone of plants rich biofilm, can effectively remove organic contaminants.
3) A Keman ecological purification technology, a specialized contractor of cloth ambition be placed in the wetland, pool or building, it can invest 245m3/m2 specific surface area because gainful microorganisms and algae in water breeding, cater addition surface supplemented aerobic and anaerobic conditions, tin greatly depress water COD, NH3, TP, TN, using such technology units of South China University of Technology, for the handling of servant sewage, wastewater treatment plant Gongbei sewage treatment. The role of water treatment chemicals processing
