Question

The sun can be used to heat your home in two ways．The first is called passive solar heating because no mechanical equipment is used．Windows in the house are positioned to allow a large amount of sunlight in during the day．As sunlight passes through the windows, it heats up the walls and floors in the room．These radiate the heat slowly, keeping the room warm longer after the sun has set．Thick curtains are lowered at night to keep the heat in．During our coldest months, an extra heating source, such as a furnace(火炉).will be needed to help the passive solar house.

    The second way to heat your house is with active solar heating．Mechanical aids (things that help) are used．Specially setup solar panels (镶板) are fitted on the roof, collecting the rays from the sun．Under the panels are a network of water pipes．The panels heat up in the sunlight and in turn heat the water in the pipes．The hot water is then stored in a special holding tank, usually in the basement of the house．It is now ready to be piped into radiators in the house, giving heat to the rooms.

1．What does solar have something to do with?

A．the wind.

B．The rain.

C．The sun．

D．The air.

2．What’s the weakness of the passive solar house?

A．On the coldest days of the year some extra heater is needed to help to heat the room.

B．More curtains are needed.

C．In winter sunlight is not able to pass through the glass window.

D．Mechanical aids are expensive.

3．How does the solar energy heat the passive solar house?

A．Sunlight is kept in by the windows and walls.

B．The furnace in the middle of the room sends out heat.

C．Sunlight heats up the walls and floors through the windows and these heated walls and floors radiate the heat slowly.

D．Many windows are positioned in the house to prevent sunlight from coming in

4．What’s a radiator?

A．A large holding tank in the basement in which hot water is stored.

B．A heater in the room which radiates heat from hot water supplied, through pipes.

C．A solar panel on the roof.

D．A thick curtain keeping the heat inside the room.

5．Which of the following do you think correct?

A．The active solar house is useless in our modem life.

B．The passive solar house is more useful than the active solar house.

C．The active solar house is probably more expensive than the passive solar house.

D．The passive solar house is probably more expensive than the active solar house.
