ATask 1TextTask 2Task 3Task 4Reading ATask 1Before reading the passage,see how much you know about the water supply systems by answering the following questions.1.Why is water supply system important?2.What does a water supply system mainly consist of?Reading AWater Supply Systems Water distribution systems in buildings drawwater from the exterior mains supply networkand distribute it among consumers in a building.Interior water supply systems may be dividedinto three types:domestic,fire-protection andindustrial.To cut down the cost of constructionand service,these are frequently combined withone another.Reading A Depending on the temperature of the water,cold and hot water supply pipes are used.Reading A A cold-water supply system consistsessentially of a communication pipe,a meter box,pressure boosters,storage tanks,a piping system,valves,and water dispensing fixtures(taps).A hot-water supply system also has water heaters and filters.Reading A The communication pipe is the pipe between the mains supply and the meter box.Reading A The meter box contains a water metera device used to measure the volume of water passing into the building.Reading A The pressure boosters serve to raise pressure in the system when the guaranteed pressure in the mains supply is lower than that required to feed water to high-levels or remote consumers.Reading A The storage tanks store water from thedistribution system and release it.This ensuresa constant supply even when the distributionsystem fails to maintain pressure at the levelrequired.Storage tanks may be mounted at thehighest point in the building or installed at orbelow ground level in the basement.Reading A The function of the piping system is todistribute the water supply among the consumers.It incorporates an internal piping system which feeds the individual consumers and a supply piping system which delivers the water from the meter box to the system for the building.Reading A The valves serve to control the flow of water.In particular,the stop cock is the name given to the valve that can be used to shut off the water supply to the entire building during inspection or in emergencies.Individual stop cocks may be fitted for each consumers property.Reading A The water-dispensing fixtures,better known as taps,let the water out for use.Reading A The layout of a domestic water supply system,that is,the type and number of component parts and the piping arrangement,depends on the pressure available from the mains and that required for normal and effective functioning of the domestic system.Reading A给水系统给水系统 建筑物的给水系统的作用是从室外管网引水至建筑物内各用户。室内给水系统可以建筑物的给水系统的作用是从室外管网引水至建筑物内各用户。室内给水系统可以分为生活、消防和工业系统三种。为了降低建造和维护费用，也经常采用合用管道。分为生活、消防和工业系统三种。为了降低建造和维护费用，也经常采用合用管道。Reading

闸阀用于控制水的流量。当系统检修或发生紧急情况时，一些特殊的闸闸阀用于控制水的流量。当系统检修或发生紧急情况时，一些特殊的闸阀会切断向建筑物内的给水，这些闸阀叫做阀门。单独的阀门也可以安装在阀会切断向建筑物内的给水，这些闸阀叫做阀门。单独的阀门也可以安装在住户家中。住户家中。Reading A水通过配水器具，又叫做龙头，流出后供人们使用。水通过配水器具，又叫做龙头，流出后供人们使用。Reading
