charges are given for heavy use, but the solar system still makes sense for low-energy users such as
myself.
So much of Americans' carbon footprint results from buildings-about 43%, according to the U.S.
Department of Energy. I'm in a household of 1.5 (mom and 7-year-old), and we use only about 4
kilowatt hours of electricity per day, something we've managed through behavioral changes, such as
turning off the lights in rooms after we've exited, and through in-home efficiencies (效率), such as
swapping out all my light bulbs for energy-saving ones and using power boards that can turn off DVD
players, coffee makers and other electrical equipment.
Using less electricity means I can get by with a smaller, less expensive solar system that not only
covers my use but also produces a credit on my power bill. Going solar also meant my house was
upgraded with a time-of-use meter. This type of meter allows me to receive credit for the electricity I
produce during peak hours when electricity costs the most, but pay the least for the electricity during
off-peak hours, when I recharge my cell phone and laptop and perform other tasks requiring power.
The downsides are that I am tied in to the grid (电网) and still affected by power failure, and I now
have solar panels (太阳能电池板) that need to be cleaned. It's a subject of debate, but REC Solar said
dirty panels decrease energy production by 6% to 8%.Many panel producers recommend cleaning
panels at least once during the summer. I wash mine whenever they look dirty or dotted with bird
droppings, which is about every other week.
I think $6,000 is a small price to pay, not only for panels that should produce my next 20 years of
electricity, but also for the greenhouse gases I'm not creating.
B. The tips on reducing electricity use.
C. The benefits of using solar systems.
D. The importance of protecting the environment.
B. To save time.
C. To save energy.
D. To save money.
B. disadvantage
C. disapproval
D. disagreement
B. to protect the environment
C. to make them look better
D. to avoid power failure

| One day, when I was in high school, I saw a kid named Kyle from my class walking home from school with all his books, I thought to myself, " 1 would anyone bring home all his books for the weekend? He must really be 2 ." As I was walking, I saw several kids running toward him. They ran at him, 3 all his books out of his arms and he fell down in the dirt. His glasses went 4 and landed in the grass. He looked up and I saw this terrible sadness in his eyes. My 5 went out to him. So, I ran over to him. 6 I handed him his glasses, he looked at me and said, "Hey, thanks!" There was a big smile on his face. I helped him pick up his books, and asked him where he lived. As it 7 , he lived near me. We talked all the way home. I didn't see him before as he had gone to a private school. Over the next four years, Kyle and I became best friends. Kyle was the 8 student of our class, one of those guys that really found themselves during high school. Therefore he had the 9 to prepare a 10 speech. On the graduation day, I could see that he was 11 . So, I patted him on the back and said, "Hey, big guy, you'll be 12 !" He looked at me and smiled. He cleared his throat, and began. "Graduation is a time to 13 those who helped you make it through those 14 years. Your parents, your teachers… but mostly your friends. I am here to tell all of you that being a friend to someone is the best 15 you can give him." I just looked at my friend with 16 as he told the story of the first day we met. He had planned to 17 himself over the weekend and was carrying his books home. "Thankfully, nothing happened. My friend 18 me from doing the unspeakable." Not until that moment did I realize that you should never underestimate (低估) the 19 of your actions. With one small gesture you can 20 a person's life. For better or for worse. | ||||
