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.

Why was the plant hemp essential to worldwide trade in the past（　）

A:Ships' ropes were made from it. B:Hemp was a very profitable export. C:Hemp was used as fuel for ships. D:Hemp was used as food for sailors.

The Republican Party has lost its mind. To win elections, a party needs votes, obviously, and constituencies. First, however, it needs ideas. In 1994--95, the Republican Party had after long struggle advanced a coherent, compelling set of political ideas expressed in a specific legislative agenda. The political story of 1996 is that this same party, within the space of six weeks, then became totally, shockingly intellectually deranged.
Then, astonishingly, on the very moment of their philosophical victory, just as the Republicans prepared to carry these ideas into battle in November, came cannon fire from the rear. Pat Buchanan first came out to declare a general insurrection. The enemy, according to Buchanan, is not the welfare state. It is that conservative icon, capitalism, with its ruthless captains of industry, greedy financiers and political elites (Republicans included, of course). All three groups collaborate to let foreigners--immigrants, traders, parasitic foreign-aid loafers--destroy the good life of the ordinary American worker.
Buchananism would support and wield a big and mighty government apparatus to protect the little guy from buffeting, a government that builds trade walls and immigrant-repelling fences, that imposes punitive taxes on imports, and that polices the hiring and firing practices of business with the arrogance of the most zealous forcer.
Republicans have focused too much on the mere tactical dangers posed by this assault. Yes, it gives ammunition to the Democrats. Yes, it puts the eventual nominee through a bruising campaign and delivers him tarnished and drained into the ring against Bill Clinton.
But the real danger is philosophical, not tactical. It is axioms, not just policies, that are under fire. The Republican idea of smaller government is being ground to dust--by Republicans. In the middle of an election year, when they should be honing their themes against Democratic liberalism, Buehanan’s rise is forcing a pointless rearguard battle against a philosophical corpse, the obsolete paleoconservatism--a mix of nativism, protectionism and isolationism--of the 1930s.
As the candidates’ debate in Arizona last week showed, the entire primary campaign will be fought on Buchanan’s grounds, fending off his Smoot-Hawley-Franco populism. And then what After the convention, what does the nominee do Try to resurrect the anti-welfare state themes of the historically successful ’94 congressional campaign
Political parties can survive bruising primary battles. They cannot survive ideological meltdown. Dole and Buchanan say they are fighting for the heart and soul of the Republican Party. Heart and soul, however, will get you nowhere when you’ve lost your way--and your mind.
Which of the following can best describe the eventual nominee of the Republic Party of the election

A:"from a scratch." B:"on the ropes." C:"out of patience." D:"under attack."

What equipment on a ship was made from hemp

A:Ropes. B:Waterproof cloth. C:Engine fuel. D:Life rafts.

As in the field of space travel, so in undersea exploration new technologies continue to appear. They share a number of similarities with each other — as well as some important differences.
Manned submersibles (潜水器), like spaceships, must maintain living conditions in an unnatural environment. But while a spaceship must simply be sealed against the vacuum of space, a submersible must be able to bear extreme pressure if it is not to break up in deep water.
In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other hand, men paved the way, only recently have unmanned remote-operated vehicles (ROVs) been put to use.
One reason for this is that communicating with vehicles in orbit is much easier than talking to these underwater. A vacuum am ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles—particularly ROVs— operate at the end of long ropes.
For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship’s position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar (声纳) must be laid out in advance on the ocean’ floor in the area of a dive to locate the vehicle’s position.
Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: Going to the ocean depths doesn’t require the power necessary to escape Earth’s gravity. Thus, it remains far less expensive.

Ocean exploration is not so expensive as space travel mainly because （　）.

A:it is not affected Earth’s gravity B:most undersea vehicles operate at the end of long ropes C:ROVs have been put to use D:there is no need for submersibles to get away from Earth’ s gravity

Kite
Kite flying is the sport of sending up into the air, by means of the wind, a light frame covered with paper, plastic or doth. The frame can be one of many different shapes and is attached to a long string held in the hand or wound on a drum. Kites have a long history practical application and many different types of kite have been developed to serve various purposes.
The ancient Chinese used bird-kites to carry ropes across rivers and valleys. The current folding kite which will dive excitingly is an improved type of such a kite. With its long flat body and single pair of bird like wings, it looks just like a large bird in the air. The modern version is usually made of tissue paper rather than the traditional silk.
Man-lifting kites were developed in ancient times, again by the Chinese, for getting information from walled cities and army camps. In fact, as recently as World War Ⅱ, German U-boats flew kites from their towers to lift people into the air to watch the land. These kites, which are no longer in existence, were made of lightweight cloth. They were much larger and stronger than the Chinese ones. Their design, however, was simply that of the cutter kite. Smaller in size, this type of kite is still very popular as a toy for children, being easy to make with a diamond-shaped frame, no wings and brown-paper covering.
Box kites are another type of kite found in toy shops today. The first box kite, named for its box-like body, was developed in the 19th century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early airplanes. These kites are the ancestors of a heavier version of the box kite, called the double box kite, which consists of two main sections, placed side by side. Developed for the peacetime purpose of fishing in strong sea wind, it is the only modern kite described which has practical value. A long-lasting plastic material has to be used for this kite, which carries fishing lines.
