A recent Auburn University study provides some real numbers to back a theory we’ve all known was true for some time—planting a shade tree near your home reduces energy bil

ls significantly in the spring and summer months. The study, conducted in Auburn,
Alabama, included 160 homes with different levels of shade. Each home’s energy usage was monitored and compared to other houses with similar energy— using patterns, size, type of cooling system, etc. Here are some highlights from the study:
Houses with trees on the west side of their home had a “much lower power bill”.
Older homes had the most shade coverage, because people did not use to rely on air conditioning as much to keep them cool.
Children under age 12 consume the most power in a home as they watch television, play games and frequently leave lights on.
Fall and early winter are the perfect seasons to plant a tree. This time of year many nurseries（苗圃）are trying to reduce their inventory of trees heading into the winter, so you may find a deal on trees easily to plant around your lot.
While you have the spade out, consider planting a tree near your outside air conditioning unit. The shade will keep the unit cooler and help it operate more efficiently. Be sure to plant far enough from the unit to allow proper airflow, and account for the tree’s growth over time.
It actually hurts to watch the trees being knocked over when land developers plan neighborhoods be

cause trees could provide much needed shade to new homeowners, reducing their electric bill and the amount of energy they consume. Hopefully this study, and more like it in the future, will encourage developers and builders to plan around trees as much as possible to offer homeowners a shaded lot.

第三部分阅读理解（共20小题；每小题2分, 满分40分）
阅读下列短文, 从每题所给的四个选项（A、B、C和D）中, 选出最佳选项, 并在答题卡上将该项涂黑。
Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choices, we now hear about our “food print”, the amount of land needed to supply one person’s nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown loc

ally in a hothouse? Do we get the Granny Smiths from the farmers’ market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food．
Despite the complexities, t

here are some general guidelines you can follow．For instance, eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consumption of red meat because of its too much fat content．Beyond that, there are environmental reasons, too．Raising food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant-based one．
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go? You may not think so when seeing the true costs．Based on a survey, manufacturing the 30-plus billion plastic water bottles can produce more than 2．5 million tons of carbon dioxide and use three times the amount of water in the bottle．Adding in transportation, the energy used comes to over 50 million barrels of oil equivalent （等价物）．Consequently, skip the bottled water and drink tap water, both at home and at restaurants．Additionally, bottled water is not necessarily cleaner than tap．
1．In Paragraph 2 the author puts forward three questions mainly ______．
A．to prove Americans have less food to choose from
B．to show us the shopping habits of most Americans
C．to indicate Americans tend to buy food from abroad
D．to remind people to reconsider their food purchase
2．The doctor recommends eating less red meat partly because ______．
A．it contains too much fat
B．it costs a lot in transportation
C．it is too low on the food chain
D．it isn’t related to climate change
3．According to the text, which of the following is true?
A．Americans all prefer to buy cherry tomatoes from Mexico．
B．The plant-based diet is responsible for the climate change．
C．Americans have a variety of food to choose from．
D．Organic produce is the only choice for Americans．
4．Based on the last paragraph, we know that ______．
A．bottled water is cleaner than tap water
B．tap water is economical as well as eco-friendly
C．bottled water is more available than tap water
D．tap water uses one-third the cost of bottled water
5．What is the best subtitle for the last paragraph?
A．Skip bottled water, carry tap B．Drink bottled water
C．Produce plastic water bottles D．Save water resources

Section A 30%
Directions：Read the following four passages. Each passage is followed by several questions. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
Riding was the favourite activity of Thomas Jefferson, who was the third President of the United States. He usually rode good horses.
One day, he was riding outside Washington, when a jockey (赛马师) came near. He did not know the President, but his professional eye was attracted by Mr. Jefferson’s horse. He stopped and said that he wanted to buy the horse, but Mr. Jefferson politely refused his offer.
The jockey offered more money for the horse, because the closer he looked at the horse, the more he liked it. All of his offers were refused, which made him angry. He then became rude, but his rudeness left as little an impression as his money, for Jefferson had a very good temper. At last, he hit Mr. Jefferson’s horse with his whip, getting it to run suddenly. This would have thrown a less skillful rider to the ground, but Jefferson stayed on his seat, and controlled his horse well.
The jockey then gave up. He rode with Mr. Jefferson side by side and began to talk with him about politics. Jefferson joined in the conversation. When they got into the city and came close to the gate of the presidential mansion (总统府), Mr. Jefferson stopped, and politely invited the man to enter.
The jockey was surprised and asked, “Why? Do you live here?”
“Yes” was the simple reply.
“Why, stranger, what’s your name?”
“My name is Thomas Jefferson.”
Embarrassed, the man quickly left, while the President looked at him with a smile and then rode through the gate.

Breathe, wave and smile.Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement(graduation ceremony).
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.
Our principal, Mr Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).
Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”
Then came the core(the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.
1. What’s the article mainly about?
