There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration （集中）of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution.
Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a “greenhouse effect” - raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth’s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset（抵消）each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people don’t think about the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth?
72. As pointed out at the beginning of the passage, people used to think that air pollution ________.
A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaged effect on health
D. existed only in urban and industrial areas
73. As to the greenhouse effect, the author ________.
A. shares the same view with the scientists
B. is uncertain of its happening
C. rejects it as being ungrounded
D. thinks it will destroy the world soon
74. It can be concluded from the last paragraph that ________.
A. lowering the world’s temperature only a few degrees would lead major farming areas to disaster
B. raising the world’s temperature only a few degrees would not do much harm to life on earth
C. almost no temperature variations have occurred over the past decade
D. the world’s temperature will remain constant in the years to come
75. This passage is mainly about ________.
A. the greenhouse effect
B. the burning of coal and oil
C. the potential effect of air pollution
D. the likelihood of a new ice age

E
There’s talk today about how as a society we’ve become separated by colors, income, city vs suburb, red state vs blue. But we also divide ourselves with unseen dotted lines. I’m talking about the property lines that isolate us from the people we are physically closest to: our neighbors.
It was a disaster on my street, in a middle-class suburb of Rochester Town, several years ago that got me thinking about this. One night, a neighbor shot and killed his wife and then himself; their two middle-school children ran screaming into the night. Though the couple had lived on our street for seven years, my wife and I hardly knew them. We’d see them jogging together. Sometimes our children would share cars to school with theirs.
Some of the neighbors attended the funeral（葬禮）and called on relatives. Someone laid a single bunch of yellow flowers at the family’s front door, but nothing else was done to mark the loss. Within weeks, the children had moved with their grandparents to another part of the town. The only indication that anything had changed was the “For Sale” sign in front of their house.
A family had disappeared, yet the impact on our neighborhood was slight. How could that be? Did I live in a community or just in a house on a street surrounded by people whose lives were entirely separate? Few of my neighbors, I later learned, knew others on the street more than casually; many didn’t know even the names of those a few doors down.
Why is it that in an age of low long-distance expenses, discount airlines and the Internet, when we can create community anywhere, we often don’t know the people who live next door? Maybe my neighbors didn’t mind living this way, but I did. I wanted to get to know the people whose houses I passed each day – not just what they do for a living and how many children they have, but the depth of their experience and what kind of people they are.
What would it take, I wondered, to break through the barriers between us? I thought about childhood sleepovers（在外過夜）, and the familiar feeling and deep understanding I used to get from waking up inside a friend’s home. Would my neighbors let me sleep over and write about their lives from inside their own houses?
72. The underlined word “this” in the second paragraph probably refers to the talk about ____.
A. how a society is divided by dotted lines 
B. the property lines separating us from our neighbors
C. the couple’s death                  
D. understanding each other between neighbors

A. The husband killed himself.
B. The couple had the habit of jogging together.

D. The author never knew the couple until they died seven years later.

A. had once slept in the open air outside
B. had slept in his friend’s home more than once
C. had slept at home but woke up to find himself inside his friend’s home
D. used to live in his friend’s home
