Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her breast wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby falls down to the ground and squeaks(尖叫) for help. Then the older ones swoop (俯冲) down and try to pick it up. If they fail to do so, it will die, Often hundreds of dead baby bats can be found lying on the ground at the foot of a tree.
The passage tells us that there is no difference between, the flying fox and the ordinary hat in ______. ()
A．their size
B．their appearance
C．the way they rest
D．the kind of food they eat
Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.
This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.
World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.
Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.
This passage chiefly discusses______.
A．the growth of world population
B．one type of the exponential rate
C．the population problem of more rapidly growing countries
D．the possible ways of dealing with the rapid population growth
1、In prehistoric times people____.

Some experimental evidence tends to show that alcohol reduces fear in an approach-avoidance situation. Conger trained one group of rats to approach a food goal and trained another group to avoid electric shock. After an injection of alcohol the pull away from the shock was measurably weaker, while the pull toward food was unchanged.
The obvious troubles experienced by alcoholic persons appear to contradict the learning theory in the explanation of alcoholism. The discomfort, pain, and punishment they experience should presumably discourage the alcoholics from drinking. The fact that alcoholic persons continue to drink in the face of family discord, loss of job, and illness is explained by the proximity of the drive of reduction to the consumption of alcohol; that is, alcohol has the immediate effect of reducing tension while the unpleasant consequences of drunken behavior. came only later. The learning pattern, therefore, favors the establishment and repetition of the resort to alcohol.
In fact, the anxieties and feelings of guilt caused by the consequences of excessive alcohol drinking may themselves become the signal for another time of alcohol abuse. The way in which the desire for another drink could be caused by anxiety is explained by the process of stimulus generalization: conditions or events securing at the time of reinforcement tend to acquire all the features of stimuli. When alcohol is consumed in association with a state of anxiety or leer, the emotional state itself takes on the properties of a stimulus, thus triggering another time of drinking.
The role of punishment is becoming increasingly important in explaining a cause of alcoholism based on the principles of learning theory. While punishment may serve to suppress a response, experiments have shown that in some cases it can serve as a reward and reinforce the behavior. Thus if the alcoholic person has learned to drink under conditions of both reward and punishment, either type of condition may trigger renewed drinking.
Conger's experiment with two groups of rats
A．concludes that alcohol drinking may affect appetite.
B．confirms the findings of other academic researchers.
C．shows that alcohol minimizes fear.
D．disproves learning and reinforcement theory.
