10．I know a woman who complained about how expensive it was to stay warm in her house in winter．Her problem was that she was wearing shorts an T-shirts inside and then turning the thermostat（恒温器）way up，which caused her furnace to use more natural gas and her heating bill to climb．By putting on long pants and long-sleeve shirts，she could keep warm and turn the thermostat down，which saved money．
Each degree you lower your thermostat can save you up to 3 percent on heating．When you are paying to heat the air，you certainly don't want to lose it．So it's also important to identify areas where warm air gets out or cold air gets in．And the fixes don't have to be expensive．
I traced a cold draft in my living room to the old keyhole in the front door．Since the keyhole was no longer used，I fixed it with packing material and the draft disappeared．I also realized that my bedroom was cold because I was leaving the door open．When I keep it closed，I don't have to pay for more heat to make the temperature in the room comfortable for me．
Another idea came to me on one of those winter days when it's still cold outside but the sun heats up the inside of the car so much that you put the window down．On sunny winter days，I raised the blinds（百叶窗）to let some of that warmth come through the windows．Letting that sun in has a benefit beyond helping to heat my house．In a long winter，those occasional bright rays also boost my spirits．It's not as good as a trip to Florida，but definitely cheaper．

28．Why did the woman complain？D
A．She was short of money          
B．She felt cold in her house．
C．She lacked enough clothes．
D．She paid too much for heating．
29．Which can replace the underlined word"draft"mean？A
A．air    B．smoke    C．sunlight    D．natural gas
30．Which is the author's way of keeping warm on sunny winter days？B
A．Opening windows          
B．putting blinds on
C．staying in a heated car．
D．Having a trip in Florida
31．What is the main purpose of the text？B
A．To introduce new technologies．
B．To give some simple suggestions．
C．To persuade people to be economical．
D．To show the importance of energy saving．
