Recently, a possible alternative way of producing paper has been suggested by agriculturalists and environmentalists: a plant called hemp. Hemp has been cultivated by many cultures for thousands of years. It produces fiber, which can be made into paper, fuel, oils, textiles, food, and rope. For centuries, it was essential to the economies of many countries because it was used to make the ropes and cables used on sailing ships; colonial expansion and the establishment of a world wide trading network would not have been feasible without hemp. Nowadays, ships" cables are usually made from wire or synthetic fibers, but scientists are now suggesting that the cultivation of hemp should be revived for the production of paper and pulp. According to its proponents, four times as much paper can be produced from land using hemp rather than trees, and many environmentalists believe that the large-scale cultivation of hemp could reduce the pressure on world"s forests. However, there is a problem: hemp is illegal in many countries of the world. This plant, so useful for fiber, rope, oil, fuel and textiles, is a species of cannabis(大麻), related to the plant from which marijuana is produced. In the late 1930s, a movement to ban the drug marijuana began to gather froce, resulting in the eventual banning of the cultivation not only of the plant used to produce the drug, but also of the commercial producing—producing hemp plant. Although both George Washington and Thomas Jefferson grew hemp in large quantities on their own land, any American growing the plant today would soon find himself in prison—despite the fact that marijuana cannot be produced from the hemp plant, since it contains almost no THC (the active ingredient in the drug). In recent years, two major movements for legalization have been gathering strength. One group of activists believes that ALL cannabis should be legal—both the hemp plant and the marijuana plant—and that the use of the drug marijuana should not be an offense. They argue that marijuana is not dangerous or addictive, and that it is used by large numbers of people who are not criminals but productive members of society. They also point out that marijuana is less toxic than alcohol or tobacco. The other legalization movement is concerned only with the hemp plant used to produce producing; this group wants to make it legal to cultivate the plant and sell the fiber for paper and pulp production. This second group has had a major triumph recently: in 1997, Canada legalized the farming of hemp for fiber. For the first time since 1938, hundreds of farmers are planting this crop, and soon we can expect to see pulp and paper produced from this new source. Way do agriculturalists think that hemp would be better for paper production than trees
A. It is cheaper to grow hemp than to cut down trees.
B. More paper can be produced from the same area of land.
C. Hemp produces higher quality paper.
D. It is easier to find hemp than to find trees.

The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where earthquakes are most likely to occur are called earth quake "belts" where government is spending a great deal of money and is working hard to help discover the answer to these two questions; 1. Can we predict earthquakes 2. Can we control earthquakes To answer the first question, scientists are looking very closely at the most active fault(断层) systems in the country, such as the San Andreas fault in California. A fault is a. break between two sections of the earth"s surface. These breaks between sections are the places where earthquakes occur. Scientists look at the faults for changes, which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately. And the control" of earthquakes is even farther away. Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was put into a layer of rocks 4,000 meters below the surface of the ground. Shortly after this injection of water, there were a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. When the water "oiled" the fault, the fault became slippery and the energy of an earthquake was released. Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this knowledge to prevent very big, destructive earthquakes, that is, scientists could inject some kind of fluid-like water into faults and change one big earthquake into a number of small, harmless earthquakes. What did scientists learn about earthquakes at the Rocky Mountain Arsenal
A. They occur at about 4,000 meters below ground level.
B. The injection of water into earthquake faults prevents earthquakes from occurring.
C. They are usually caused by the oil in the faults.
D. Harmful earthquakes can be possibly prevented by causing small, harmless earthquakes.
Changes in the economy, Europe"s reunification and technological evolution challenge our educational system. Vocational education will be particularly touched. It will be then necessary to intervene in the field of higher vocational education. Their level of education has to be qualitatively redefined and adapted to current demands. Professionals will have new chances of promotion through these reforms. At this point, vocational education has to define itself as being equal to high school-university courses, while keeping its particularities. As far as employment opportunities are concerned, it is assumed that graduates from colleges of higher education have more or less the same chances to find a job as university graduates. In some areas, the former will probably even find employment easier, as their practical work experience is by far larger than university students. These may possess a much larger theoretical background as they start working but would in most cases need more time to get familiar with the practical side of their job. Those among higher vocational schools that satisfy the prerequisite for courses and research-development studies will be upgraded to colleges of higher education. We are happy to see that our higher vocational colleges (engineering school for example) have already good contacts with economical circles. By putting together different subjects and research-development facilities into a dozen of colleges of higher education, we will be able to guarantee quality education and a better use of already existing technical and financial means. We thus have to group schools together, most of which are being at present geographically separated. Vocational education, also giving the possibility to deepen professional knowledge through attractive courses, must offer a real alternative to general culture schools. The creation of the new advanced vocational diploma as well as the colleges of higher education must contribute to the education of our future elite. Every youngster will thus have the possibility to better develop his/her own abilities. The creation of the new advanced vocational diploma is ______.
A. giving the possibility to deepen professional knowledge
B. a real alternative to general cultural schools
C. equal to diploma of colleges of higher education
D. vital to the education of our future elite
