Mosquitoes have an interesting life cycle. The female mosquito bites a person or animal in order to get some blood. She needs this blood before she can lay her eggs. Second, she flies to an area of water and deposits (存放),40 her eggs in the water. In a few days the eggs open, and the baby mosquitoes, called larvae, come out. In a short time, they will be mature and fly away.
It is interesting to note that only the female will bite for blood. She has a special mouth which can go into an animal's skin or a person's skin. On the other hand, the male mosquito can only drink plant juices with his mouth.
The author suggests that all mosquitoes like ______.
A.blood
B.wet areas
C.cold weather
D.dry climates

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

To the professional anthropologist, there is no intrinsic superiority of one culture over another, just as to the professional linguist there is no intrinsic hierarchy among languages.
People once thought of the languages of backward group as savage, undeveloped forms of speech, consisting largely of grunts and groans. While it is possible that languages in general began as a series of grunts and groans. It is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex, delicate, and ingenious pieces of machinery for the transfer of ideas. They fall behind our Western languages not in their sound patterns or grammatical structures, which usually are fully adequate for all language needs, but only in their vocabularies, which reflect the objects and activities known to their speakers. Even in this department, however, two things are to be noted: 1. All languages seem to possess the machinery for vocabulary expansion, whether by putting together words already in existence or by borrowing them from other languages and adapting them to their own systems. 2. The objects and activities requiring names and distinctions for "backward" languages, while different from ours, are often surprisingly numerous and complicated. A Western language distinguishes between what is close to the speaker, or to the person addressed, or removed from both, or out of sight, or in the past, or in the future.
This study of language, in turn, casts a new light upon the claim of the anthropologists that all cultures are to be viewed independently, and without ideas of rank or hierarchy.
The statement that "every group has a culture" grows out of the author's ______.
A.definition of culture
B.feeling about human beings
C.bias in regard to civilized humans
D.philosophy
