III. Reading Comprehension
Section A
Directions: For each blank in the following passages there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.
When we think of green buildings, we tend to think of new ones----the kind of modern, solar-paneled masterpieces that make the covers of architecture magazines．But the US has more than 100 million existing homes, and it would be incredibly 51 to tear them all down and 52 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 53 carbon emissions (排放) from a(an) __54 _ energy-efficient (节能) home to make up for the 55 lost by destroying an old one．
So in the broadest sense, the greenest home is the one that has already been built．But at the same time, 56 half of US carbon emissions come from heating, cooling and powering our 57 , offices and other buildings．"You can't deal with climate 58 without dealing with existing buildings," says Richard Moe, the president of the National Trust．
With some exceptions, the oldest homes tend to be the 59 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 60 over time and let in more outside 61 .
62 , there are a vast number of relatively simple changes that can green older homes, from 63 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 64 property owners from rising power 65 .

Section B
Directions: Read the following four passages. Each passage is followed by several questions or unfinished statements. 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．
A
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government must take care to control gene technology.
66. What does “these two killers” in the second paragraph refer to?
A. Gene technology and another treatment of the two diseases.
B. The two murderers who killed the cloned baby.
C. The two diseases of cancer and heart disease.
D. Hereditary diseases and cancer.
67. What’s the main idea of the third paragraph?
A. How gene technology can be applied in the field of treating hereditary diseases.
B. Gene technology can be used to clone human babies.
C. Gene technology can help people to give birth to a baby.
D. Gene technology can help the English imperial family out.
68. In what way gene technology can help to treat hereditary diseases?
A. Using gene technology, people with hereditary diseases can have more living days.
B. Using gene technology, the scientist finds the wrong gene and corrects it.
C. Using gene technology, human babies can be cloned.
D. Doctors can cure cancer and heart disease with the help of gene technology.
69. What is the main purpose of writing this passage?
A. Expressing the writer’s idea that gene technology will benefit people.
B. Telling people the disadvantages of gene technology.
C. Telling the readers that gene technology will not benefit people.
D. Explaining that gene technology will also do harm to the humanity.
