“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished(减少) lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person"s individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won"t work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”

A. Rocket scientists are making researches on people’s health.
B. It"s obvious that air pollution has a bad effect on people’s health.
C. People aren"t sure whether taking deep breaths on a smoggy day is bad.
D. People often have a hard time when taking deep breaths on a smoggy day.
67. The word "vulnerable" in Paragraph 3 probably means _________.
A. easy to be hurt B. easy to be protected
C. easy to be used D. easy to be saved
68. The main idea of Paragraph 3 is _________.
A. that even small risk from particulate causes big problems
B. that air pollution often leads to heart attack
C. who are most likely to get affected
D. that we shouldn"t worry about the average low risk

First of all, there’s Dr Stone. He’s a man of about sixty five, with gray hair and a friendly face. He gave up his work a short while ago and is now traveling round the world before he retires to some quiet country village. As a young man, he served for many years as a doctor in the army and visited many countries. He’s told us a lot about the city to which we are going.
Then there’s “Grandmother”. I call her that because her name escapes me. In spite of being a grandmother, she looks rather young, not more than fifty, she’s on her way to visit a daughter who went to Australia some years ago. Naturally she is very excited at the thought of seeing her again, and her three grandchildren, whom she has never seen.
Then there’s a man I don’t care for very much, an engineer by the name of Barlow. He has been on leave in England and is now returning to his work in Singapore.
The other person who sits at our table is Mrs. Hunt. I’ve found out hardly anything about her. She’s extremely quiet and rarely talks, except to consult(咨询)the doctor about children’s various illness. She’s on her way to join her husband in India.
64. What can we know about Mr. Stone?

People have wondered for a long time how their personalities and behaviors are formed.It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are, of course, extremely interested in these types of questions.They want to explain why we possess certain characteristics and exhibit certain behaviors.There are no clear answers yet, but two distinct schools of thought on the matter have developed.As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory.The controversy is often referred to as “nature/nurture”.
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors.That our environment has little, if anything, to do with our abilities, characteristics, and behavior is central to this theory.Taken to an extreme, this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts.
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act.A behaviorist, B.F.Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings.The behaviorists’ view of the human being is quite mechanistic; they maintain that, like machines, humans’ respond to environmental stimuli as the basis of their behavior.
Either of these theories cannot yet fully explain human behavior.In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes.That the controversy will continue for a long time is certain.
69.Which of the following statements would the supporters of the “nature” theory agree with?
A.A person’s instincts have little effect on his actions.
B.Environment is important in determining a person’s behavior and personality.
C.Biological reasons have a strong influence on how we act.
D.The behaviorists’ view correctly explains how we act.
70.Concerning the nature/nurture controversy, the writer of this article____________.
A.supports the nature theory
B.supports the nurture theory
C.believes both are completely wrong
D.thinks that the correct explanation of human behavior will take ideas from both theories.
71.In the United States, Black people often score below White people on intelligence tests.With this in mind, which of the following statements is NOT true?
A.Nature proponents would say that Whites are genetically superior to Blacks.
B.Supporters of the nature theory would say that Whites score well because they have a superior environment.
C.Behaviorists would say that Blacks often lack the educational and environmental advantages that Whites enjoy.
D.Nurture proponents would disagree that Blacks are biologically inferior to Whites.
D
Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm-blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.
Getting enough water to survive is a major problem for all desert animals. Some desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.
Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.
The camel---often called the ship of the desert---is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps. A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.
71. Desert animals are usually more active at night because ______.
A. it is cooler at night B.it is easier to find water
C.they like the dark D. they are less likely to be attacked at night
72. Which of the following desert animals can get water only from the food?
A. The camel. B. The kangaroo rat. C. The frog. D. The toad
73. Which of the following is TRUE according to the passage?
A. All the desert animals rest during the day.
B. All the desert animals don’t rest during the day.
C. Cold-blooded desert animals don’t rest during the day.
D. None of the cold-blooded desert animals go out during the day.
74. The title for this passage could probably be ________.
A. Hot Deserts B. Desert Animals
C. How Desert Animals Get Water D. Ways To Escape the Desert Heat
75. The underlined word “burrows” in the first paragraph can be replaced by _________.
