D
Many Chinese have been greatly shocked by the traffic accident caused by the drunk driver Sun Weiming, who has killed five and injured some others in Chengdu, Sichuan. However, such a case is not rare.
Today, the traffic accidents may have been regarded as a social problem. The car has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral (道德的) rights of others. In fact, the enemies of society on wheels are rather harmless but just ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even far beyond carelessness that can be imagined.
Researchers have estimated that as many as 80 percent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can change drivers’ reactions incorrectly, slow their judgment, and make them blind to the dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep his/her emotions under control.
Yet the .irresponsibility; that accounts for much of the problem isn't only put upon drivers. Street walkers regularly ignore or break traffic regulations. They are blamed in most vehicle walker accidents, and many cyclists even believe that they are not subject to the basic rules of the road.
Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicles have been raised both at the point of manufacture and through regular road inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to make people believe that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things present a threat to those with whom they share the road.
67. Traffic accidents may be regarded as a social problem because
A. auto driving has become dangerous and harmful in today's society
B. people usually pay no attention to law and morality when driving
C. they have caused serious psychological problems among drivers
D. the car has killed and disabled more people than any weapon in history
68. Who are NOT mentioned as being responsible for the road accidents?
A. Careless bicycle--riders.             B. Careless people walking in the street.
C. Irresponsible auto drivers.            D. Irresponsible auto manufacturers.
69. Discussing solutions to traffic accidents, the author seems to be
A. doubtful and hopeless               B. angry and disappointed
C. objective and concerned             D. anxious and annoyed
70. The author writes this passage to
A. show his worries about drunk driving
B. help protect street walkers from car accidents
C. discuss traffic problems and possible solutions
D. warn auto drivers to refuse drunk driving

ABCD請按實際情況填寫。其他請參照下表填寫。
A, B, C, D, E(AB), F(AC)

A. Control of Respiration
B. Basic tips for preserving cut flowers
C. Role of Respiration
D. Most Important Aspect of Flower Care
E. Need for Clean Water
F. Ways of Stopping Respiration

【小題1】
While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flowers for a week or more without floral preservatives(which contain biocides that kill bacteria and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.
【小題2】
An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
【小題3】
Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), generates the energy the flower needs to give the flower its shape and colour. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.
【小題4】
How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.
【小題5】
Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白劑) can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water. The water and solution should also be replaced each day.
