[单项选择]Accidents caused by car doors being opened into the path of oncoming vehicles or cyclists are common in cities. But these incidents could become a thing of the past, if doors that react to potential impacts catch on.
……
The current prototype looks like a normal ear door, but an extra metal bar runs through its centre and connects to the ear’s flame between the hinges. In normal mode, the bar moves freely and doesn’t affect the door’s movement.

Most forest fires are caused by human carelessness or ignorance. Forest fire prevention, therefore, is mainly a problem of creating better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger.

Others are caused by hunter, hikers(徒步旅行者), fishermen, or woods workers who are careless in disposing of their smoking materials.

[单项选择]

Prolonging Human Life
Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have
A. the need to prolong the lives of old people.
B. the need to enrich the life of the retired people.
C. the need to build profit-making nursing homes.
D. the need to take care of a sick and weak person.
