It's not always easy to run an energy efficient house. But there are some simple things anyone can do.

Go LED with your lighting.

There are sevenal benefis to switching to energy efficient light bulbs. One of them is saving money- though the LED bulbs might cost more than traditional bulbs, the average saving on LED bulbs is $ 75a year._ 1.LED bulbs can last years or even decades.

Don't run your air conditioner constantly

As the weather starts to warm, you might be thinking about the right time to turrn on your air conditioner. _ 2.Air conditioner units are among the most energy-consuming appliances in your home. Using electrical fans instead of your air conditioner is much more efficient and it's a big money saver, too.

3.

On those days when you treat a large crowd and are low on time，don't beat yourself up if you have to use disposable(一次性的) dishware. This method reduces your water usage and saves energy. And as a bonus, if your city offers roadside recycling, your paper plates may qualify.

Update your insulation(隔热)

All that work you're doing to save energy in your home could go to waste if it's not properly insulated. If you can't insulate the whole house, pay special attention to the roof: it reduces air flow from outide. By updating your insulation,you're saving money.4.

Take showers instead of baths

A full bathtub requires about 70 gallons of waler.5.Showers are quite dfferent---taking a five-minute shower uses only 10 to 25 gallons!

A.But do you really have to?

B.You should use your air conditioner smartly.

C.Tum off water when not using it.

D.Plus, you needn't change them frequenly.

E.Don't feel guilty about using paper plates.

F.And it's also easier to control your home temperature.

G.Even if you don't fill it to the top, it still uses much more water.

Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (双层玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.

Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.

The Ouchidas are victims of indoor air pollution, which is net given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”

The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants produced in most households seldom build up to dangerous levels.

1. It can be learned from the passage that the Ouchidas’ house __________

A. is well worth the money spent on its construction

B. is almost faultless from the point of energy conservation

C. failed to meet energy conservation standards

D. was designed and constructed in a scientific way

2. What made the Ouchidas’ new house a horrible dream?

A. Lack of fresh air.                                  B. Poor quality of building materials.

C. Gas leak in the kitchen.                          D. The newly painted walls.

3. The underlined word “accentuate” in the third paragraph most probably means ___________.

A. control        B. worsen               C. relieve               D. improve

4. This passage is most probably taken from an article entitled “_________”.

A. Energy Conservation                             B. Houses Building Crisis

C. Air Pollution Indoors                             D. Traps in Building Construction

Flying out of an airport in the United States is not always easy. You will need to complete the ticketing process, baggage check, and security clearance procedures before boarding the plane.

If you are flying on an international flight, you'd better arrive two hours before your plane is scheduled to leave. You might need more time in a busy airport in a large city. If you are traveling on a domestic (国内的) flight, you may only need to arrive at the airport 90 minutes before your plane takes off.

Every airport in the States is now moving its ticketing procedure to electronic ticketing device. By using a ticketing machine, you have the chance to choose a seat you like on the plane. If you use it to check-in your bags, you will only have to talk to the ticketing agent when you turn in your luggage to be tagged (加标签). At the same time a real person will be nearby to help you if you need it.

After you have checked in, you will have to pass through airport security. Have your ID card or passport and boarding pass ready to show the security officer when entering the security checkpoint line. Airport security is getting tight in the States today. You're not allowed to travel with any prohibited things like knifes or fireworks.

After the security staff has checked your travel documents, you shall put all of your belongings through a scanning machine and then walk through a metal detector (探测器) or a full body scanner. You need to take off your coat, belt, and sometimes your shoes to go through one of these scanners. Be sure not to have any metal in your pockets. If you do not understand a question you are asked at a security checkpoint, ask the person to repeat their question until you are able to respond with an accurate answer.
