We cannot figure out____________quite a number of insects, birds, and animals are dying out.

A.  that          B.  as           C.  why            D.  when

This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.

This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.

The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is just to be prepared.

Some nations think they must have more and more babies, more and more people, if they are to remain strong and free.

Actually, this is not so. Very often in history, small nations have conquered large ones. It’s not so much the size of the army as its organization and the technical level of its weapons. Thus, Greece took over Persia in the 300s B.C., Great Britain took over India in the 1700s, even though Persia and India had far bigger population than Greece and Great Britain.

If a nation wishes to avoid being dominated by its neighbors, its best chance is to raise its standard of living and its level of technology.This can be done best by not allowing its population to grow to such a point that it is sunk in misery and poverty. In fact, the worst way in which a nation can try to avoid being dominated by its neighbor is to increase its population to the point of misery and poverty.

If every nation tries to compete with its neighbors by raising its population, then the whole world will be sunk in misery and poverty. The nations will become weak in a disaster that will leave nothing behind that is worth dominating. No one will have gained anything. Everyone will have lost everything.

Once all this is understood, and people generally agree that population growth must not be allowed to continue, they must also come to understand how that growth can be stopped. Population grows because more people are being born than are dying. There are two ways, then, in which the growth can be stopped. You can increase the number of people who die until it matches the number of people who are being born. Or else you can decrease the number of people who are born until it matches the number of people who are dying.

The first method—increasing the death rate—is the usual way in which population is controlled in all species of living things other than ourselves, but we don’t want that, for disaster lies that way. The intelligent way is to reduce the birth rate. But how can the birth rate be reduced?

1. In paragraph 3, the word “This” refers to ______.

A．avoidance of poverty                    B．improvement of life and technology
