The garbage does not simply disappear.It may go on to a transfer station.Since it is difficult and expensive to dispose at landfill sites and incinerators .People are encouraged to recycle and compost (堆肥) picked up and taken and will be carefully buried or burned.The problem with these methods othey cost money, take up land and cause pollution.One solution to the problem of solid waste disposal is composting.Some things that can beand vegetable peels.People can compost these food products by placing them in an outdoor decompose( 分解 ) into a substance called compost.Compost, which contains plant nutrients, cto help other plants grow.Another solution to the problem of solid waste disposal is recycling.Some things can be recycled, such as glass newspapers.People can recycle used products by putting them in the "blue box".The recycled goods are melt doRecycling and composting are two ways of reducing the amount of solid waste.These methods show people a nmany things people throw away can be used again .1.Which of the following situation will be after the new ways to deal with garbage is used? ( )A、more solid waste will be producedB、less solid waste will be producedC、The same amount of solid waste will be producedD、people will stop producing solid wast2.The passage encourages people to ( )their solid wasteA、ncreaseB、burnC、hideD、recycle or compost3.The main idea for the second paragraph isA、compost is a special substance that provides your garden with nutrientsB、composting is one of ways to reduce solid wasteC、it can take a long time for compost to z, depending on what you put in the compost biD、meat, fish and grease are three things that you cannot put in your compost4.The passage is mainly concerned with ( ).A.Explain how to make compost and how it can benefit your garden.B.Choose the best way to reduce solid waste: composting or recycling.C、Compare and contrast composting with traditional garbage disposal.D、Classify the different methods of throwing away household garbage5.Which place is not a destination for solid waste?A、a transfer stationB、a landfill siteC、a recycling depotD、an incinerator

第三组：The sewage treatment system must be capable of discharging an effluent that comes within the limits of the tests. Sewage can be treated biologically so that it may be discharged with minimal damage to ecosystem. Biological treatment involves the use of living organisms to treat the sewage within the sewage treatment plant so the liquids and sludge discharged are within the standards specified.Biological treatment plants are usually built up as a module and consist of various sections.Waste matter collected from the ships sanitary appliances is led through a sanitary piping system to the treatment module. The solid matter is broken up by passing it through a screen or a series of revolving cutters. The broken up solid material, together with the waste liquid, passes into a tank containing bacteria which require oxygen and a nutrient to propagate. The nutrient is contained in the solid waste material, and oxygen is supplied by bubbling compressed air through the broken up waste. The propagated bacteria change the waste material into a sludge by aerobic digestion. The sludge is finally treated to kill the coliform. bacteria before it is passed overboard.When a biological sewage plant is started up, such as when activating a new ship or after cleaning out the tank, a pellet containing bacteria is introduced into the tank. It takes approximately one week for the bacteria to propagate and make the system fully effective. The choice of sanitary appliance cleaners requires extreme care, as many cleaners are toxic to the active bacteria. Once a biological sewage plant is made active it should not be shut down. If it is it will have to be reactivated again because the bacteria will die without a supply of nutrients and oxygen.Bacteria that require oxygen for their survival are referred to as aerobic. Aerobic bacteria are normally used in ships sewage treatment equipment. Other forms of bacteria that do not require oxygen are referred to as anaerobic. Anaerobic bacteria are used in shore based sewage treatment works where methane is obtained as a by-product for use as fuel.This passage is mainly aboutA.sewage treatment methodsB.the various sections of a sewage treatment plantsC.biological sewage treatment systemD.how the sewage treatment plants are started up
