II. Reading Comprehension
Directions: In this section, there is a passage with ten blanks. You are re quired to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item. You may not use any of the words in the bank more than once.
Passage One
When we think of green buildings, we tend to think of new ones—the kind of high-tech, solar-paneled masterpieces that make the covers of architecture magazines. But the U. S. has more than 100 million existing homes, and it would be 1 wasteful to tear them all down and 2 them with greener versions. An enormous amount of energy and resources went into the construction of those houses. And it would take an average of 65 years for the 3 carbon emissions from a new energy-efficient home to make up for the resources lost by destroying an old one. So in the broadest 4, the greenest home is the one that has already been built. But at the same time, nearly half of U. S. carbon emissions come from heating, cooling and 5 our homes, offices and other buildings. “You can't deal with climate change without dealing with existing buildings, ”says Richard Moe, the president of the National Trust.
With some 6, the oldest homes tend to be the least energy-efficient. Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that 7 over time and let in more outside air.
Fortunately, there are a ____8____ number of relatively simple changes that can green older homes, from ____9____ ones like Lincoln's Cottage to your own postwar home. And efficiency upgrades(升级)can save more than just the earth; they can help ____10____ property owners from rising power costs.
A)accommodations B)clumsy C)doubtful D)exceptions
E)expand F)historic G)incredibly H)powering I)protect
J)reduced K)replace L)sense M)shifted N)supplying
O)vast
Passage Two
For a while, biologist Arjan Boonman lived in Indonesia and spent much of his time traveling the country to make ____11____ recordings of bats. “There's a lot of deforestation there, and lots of bats are ____12____ going to go extinct, ”says Boonman, now a post doctoral researcher at Tel Aviv University in Israel. 13 by the bats, he decided to gather as much information as 14 about the various species in Indonesia, before they're gone. One day Boonman sat down on a bus next to a friendly man, who told him he'd heard a species 15 cave nectar bats making a clicking sound with their wings, perhaps using it to echolocate. Echolocation is the process whereby bats and other animals bounce sound off their surroundings to help them navigate, especially in the dark. Boonman was 16. Bat biologists, including Boonman, pretty much all assumed that bats only echolocate 17, by making sounds in their larynx. It was also generally thought that the vast majority of species in this family, known as Old World fruits bats, didn't echolocate at all, says bat expert Nancy Simmons, the curator - in - charge at the department of mammalogy at New York's American Museum of Natural History.
Boonman was convinced that it was a story worth looking into, and together they and a third scientist went to Thailand to record several different unrelated species of fruit bats(one of the better travel excuses out there). They found that several species of bats did 18 make clicking sounds with their wings, increasing the frequency of these clicks more than fivefold when they turned out the lights. This and other experiments led them to 19 that the bats use these wing clicks to find their way around, and the clicking appears to function as a primitive form of echolocation, says Simmons, who wasn't involved in the study, which was 20 in the journal Current Biology.
A)called B)published C)vocally D)feasible E)possible
F)probably G)primarily H)stop I)indeed J)conclude
K)Interested L)Fascinated M)identical N)skeptical O)audio
