　　About one-third of a typical home’s heat loss occurs through the doors and windows. Energy-efficient doors are insulated（隔热的） and seal tightly to prevent air from leaking through or around them. If your doors are in good shape and you don’t want to replace them, make sure they seal tightly and have door sweeps at the bottom to prevent air leaks. Installing（安装） insulated storm doors provides an additional barrier to leaking air.

　　Most homes have many more windows than doors. Replacing older windows with new energy-efficient ones can reduce air leaks and utility bills. The best windows shut tightly and are constructed of two or more pieces of glass separated by a gas that does not conduct heat well.

　　If you cannot replace older windows, there are several things you can do to make them more energy efficient. First, caulk(填……以防漏) any cracks around the windows and make sure they seal tightly. Add storm windows or sheets of clear plastic to the outside to create additional air barriers. You can also hang insulated window curtain on the inside—during the winter, open them on sunny days and close them at night. During the summer, close them during the day to keep out the sun.

　　A. Seal the door tightly                        B. Make door sweeps at the bottom

　　C. You don’t do anything.                    D. Both A and B

　　53. If you don’t want to replace the windows, you can do except:

　　A. Seal the windows cracks tightly.

　　B. Installing storm window or sheets of clear plastic outside

　　C.  Hang insulated window curtain inside

　　D.  Make windows sweeps at the bottom

　　54. When in the summer, we should do:

　　A. Open the windows on days and close them at night

　　B. Seal the door tightly

　　C. Close the windows on days and open them at night

　　D. Seal the windows cracks tightly

　　55. What is the purpose of writing this text?

　　A. To tell people how to save energy.

　　B. Advertise the Energy-efficient doors and windows

　　C. To tell people that they should reduce the number of windows

　　D. Energy-efficient doors and windows are useful to decrease heat loss
