The global energy crisis is approaching. What can we do? Here are some steps you
can take.
Cooling puts the greatest stress on your summer energy bill and the power grid（电
网）. Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of
your heating and cooling system can improve efficiency and comfort. Clean or replace
filter monthly or as needed.
For central air conditioning systems and room air conditioners, look for the ENERGY
STAR, the federal government’s symbol for energy efficiency. For central air, purchase
the system with the highest possible Seasonal Energy Efficiency Ratio（SEER）.
Use energy-efficient ceiling fans either alone or with air conditioning Ceiling fans do
a great job of circulating air. When used with air conditioning, fans allow you to raise the
thermostat（恒温器）and cut costs. Ceiling fans cool people, not rooms, so before you
leave, turn off the ceiling fan.
Let a programmable thermostat “remember for you” to automatically adjust the
indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10
percent. You can come home to a comfortable house without wasting energy and
creating pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home
quieter and cleaner and reduce your cooling costs up to 20 percent.
Cut your air conditioning load, and reduce pollution by planting leafy trees around
your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix
shading equipment to avoid heat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs（荧
光灯）, which provide bright, warm light while using at least two-thirds less energy,
producing 70 percent less heat and lasting up to 10 times longer than incandescent
bulbs（白炽灯）.
Drive the car that gets better gas mileage whenever possible if you own more than
one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car
that gets 20 miles per gallon to one that gets 30 mpg will save you more than $65 per
year.
Carpool. The average U.S. commuter（乘车上班族）could save about $260 a year by
sharing cars twice a week with two other people in a car that gets 20. 1 mpg—assumingthe three passengers share the cost of gas.
68. According to the passage, the thermostat is used to .
A. make rooms quieter B. control room temperature
C. turn off the air conditioner D. reduce room air pollution
69. We can conclude from the passage that the author probably discourages .
A. planting leafy trees around your home
B. turning off the ceiling fan before you leave your house
C. keeping your south-facing windows open during the day
D. using fluorescent bulbs instead of incandescent bulbs
70. According to the passage, you can save fuel by ___________.
A. using energy-efficient ceiling fans B. sharing cars with others on
workdays
C. turning off everything not in use D. reducing 10% of your car trips
every year
71. This passage is mainly about .
A. energy-saving tips B. fuel-saving tips
C. do-it-yourself tips D. environment-protecting tips

A new study has found no evidence that sunscreen, commonly used to reduce the
risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18
earlier studies that looked at the association between sunscreen use and melanoma(黑素
瘤). They said that they found flaws in studies that had reported associations between
sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of
the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率)
faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the
opposite effect, perhaps by allowing people to remain exposed to the sun longer without
burning.
The researchers said that among the problems with some earlier studies is that they
often failed to take into account that those people most at risk for skin cancer—people
with fair skin and freckles（雀斑）, for example—are more likely to use sunscreen. As a
result, it may appear that sunscreen users get cancer more often.The studies, which generally relied on volunteers to recall their sunscreen use, were
also unable to prove how well the products had been applied, said the new study.
72. The underlined word “flaws” in the 2nd paragraph most probably means .
A. evidences B. facts C. faults D. failures
73. People with fair skin and freckles .
A. seldom use sunscreen B. are more in danger of skin cancer
C. can be free from the harm of the sun D. often expose themselves to the sun
74. We can learn from the passage that .
A. sunscreen users get skin cancer more often
B. the volunteers have proved the effect of sunscreen
C. the new study was based on the experiences of volunteers
D. the number of skin cancer patients is increasing in America
75. Which of the following can be the best title for this passage?
A. Sunscreen to Prevent Skin Cancer B. Sunscreen to Increase Skin Cancer
C. Skin Cancer Caused by Sunscreen D. Skin Cancer Caused by Freckles

68. B. 根据第五段第一句…automatically adjust the indoor climate with…可以得知 the
thermostat是用来自动调节室内温度的.
69. C. 根据第八段Close blinds or shades on south-and-west-facing windows during the
day…一句可以判断C选项为错误做法，而其他三个选项文中都认为是正确做法.
70. B. 要注意审题，本题问的是save fuel.
71. A. 通篇讲的是save energy，而save fuel仅仅只是其中的一部分.
72. C. 文章第一段就开门见山指出：到目前为止还没证据表明 sunscreen会增加 skin
cancer的几率，接下来的段落也解释了使用sunscreen跟skin cancer没有必然的联系，
故排除A、B选项.
73. B. 根据第五段中的…that those people most at risk for skin cancer—people with fair
skin and freckles (雀斑),…可以找到正确答案.
74. D. 根据第三段中的…,which is increasing in incidence (发生率) faster than any other
cancer in the United States. 可以获取正确信息.
75. A. 读完全文可知：sunscreen有助于防癌.
76. exciting→ excited 我很激动。而不是使人激动的。人做主语，用-ed分词形容词。
77. parent→ parents 父母应为复数。
78. do→ does 我的朋友Cathy 作主语，谓语动词应用第三人称单数。
79. 去掉第二个of because of 后一般接名词或动名词。
80. few→ little little 修饰不可数名词，few修饰可数名词。
81. √
82. like→ as work as 做……工作，充当，担任。
83. ourselves→ us 根据句意，应该用宾格。
84. 去掉far far 表示距离，与about three kilometers 重复。
85. 在where 后加the 开幕式为特指，所以加the.
