America has a new national park. It is the Great Basin. It is the first national park in the western state of Nevada. The new park is in the eastern part of Nevada, close to the border(边界) with Utah. It is far from any city.
An American explorer John Charles Fremont travelled through the area in the early 1800's. He found the land shaped like a bowl. So he named it the Great Basin. It is a land of unusual beauty and sharp differences.
For example, you can climb a mountain covered with green forests, then cool yourself in a field of snow as you arrive at the top. Here and there, sharp rocks push out through the snow. Among the rocks you might see homes of the golden hawk (鹰), a bird that was once in danger of dying out.
You can camp in a campground on the edge of Lehman Caves. These caves are a group of large underground rooms made of limestone (石灰石). You can walk through them for about a kilometre. Before the park opened, the caves were the centre of interests for anyone travelling through this area.
The state of Nevada has wanted a national park for more than 60 years. There have always been the opposite ideas from people who believes that a park would harm(损害) mining and agriculture. The bill that set up the park, however, promises that mines will remain open, and that sheep and cows will continue to feed on the mountainsides.
Lehman Caves are______.
A．about a kilometre each
B．separated from each other
C．rooms made of limestone
D．what interest visitors most

How many years will it be before the world runs out of oil？ The question is far from an academic exercise. This year oil hit a near record high of $40 a barrel, and Royal Dutch/Shell Group downgraded its reserves by 4.5 billion barrels.
While consumers pay for perceived shortages at the pump, scientists and economists struggle to reach consensus over "proven oil reserves," or how much oil you can realistically mine before recovery costs outstrip profits. Economist Leonardo Maugeri fired up the debate that accused the "oil doomsters" of crying wolf.
Oil pessimists estimate that maximum oil production around the globe will peak in 2008 as demand rises from developing economies such as China. "If you squeezed all the oil in Iraq into a single bottle, you could fill four glasses, with the world consuming one glass of oil each year," says a physicist. "We've consumed nine bottles since oil was discovered, and we have another 9 or 10 in the refrigerator. How many more are there？ Some say five or six, but we say three."
Others believe, like Maugeri, that the number of glasses is virtually limitless. John Felmy, chief economist at the American Petroleum Institute, argues that peak oil-production estimates are so far off that. "Ever since oil was first harvested in the 1800s, people have said we'd run out of the stuff," Felmy says. In the 1880s a Standard Oil executive sold off shares in the company out of fear that its reserves were close to drying up. Some scientists said in the 1970s that we'd hit peak oil in 2003. It didn't happen.
If there is an end to the debate, advanced oil-recovery technologies will most likely find it. A new seismic survey technique, for instance, sends sound waves of varying frequencies thousands of meters belowground. Microphones arrayed aboveground record the reflected signals, and computer software models a 3-D portrait of possible oil hot spots. The surveys have now added a fourth dimension, creating a time-lapse simulation of fluid movements.
Companies are also finding sophisticated ways to mine more oil from existing wells. Flexible, coiled-tube drills that carve out horizontal side paths are a marked improvement over conventional, rigid drills that move only straight down. Using such technology, companies hope to soon harvest 50 to 60 percent of oil from existing wells, up from today's 35 percent.
Biotechnology, too is keeping the black gold flowing. University of Albert scientists are searching for microorganisms that could dilute viscous, hard-to-recover oil and make it flow more freely.
"Technology can help push peak oil production further and further out," says an expert. But only time will tell when oil production will peak.
According to the passage, which of the following statements is true？
A．How long the oil age will last is simply an academic question.
B．The oil price this year set a new record.
C．Shell Group reduced its reserves to 4.5 billion barrels this year.
D．Economists disagree with one another on how much oil you can realistically mine.

Another aspect of C that's worth mentioning here is that it is, to put it bluntly, a bit dangerous. C does not, in general, try hard to protect a programmer from mistakes. If you write a piece of(66)which will(through some oversight of yours)do something wildly different from what you intended it to do, up to and including(67)your(68)or trashing your(69), and if it is possible for the(70)to compile it, it generally will. You wont get warnings of the form. "Do you really mean to... ？" or "Are you sure you really want to... ？". C is often compared to a sharp knife :' it can do a surgically precise job on some exacting task you have in mind, but it can also do a surgically precise job of cutting off your finger. It's up to you to use it carefully.

Man’s mind is his tool Of survival.The mind is used to gain，use，store，and recall knowledge.It is his mind that enables a famer t0 know what t0 plant，when to harvest it，how to prepare food from the result.It is his mind that enables a hunter to know what he needs to make a spear，how t0 make it，and how to use it.And it is his mind that enables a blacksmith to know how t0 make iron tools.In short，it i s the mind that enables a person to know what to d0 in order tOosurvive.
Man’s mind allows long—range planning and thinking.It enables such long—range planning as required for farming，hunting，and tool making.These efforts require the ability to form. concepts of long—term cause and effect chains.“I need t0 make a spear tonight SO I can hunt tomorrow and have food for the next 7 days.”There may be environments where people could survive for a while without long—range planning，but without the results 0f knowledge like spears，fire，and 0ther technologies，people would get out—bred by Other animals and die out。
Man’s mind is his tool for survival，but like all tools，it must be properly used.The mind makes good use 0f knowledge，and knowledge can only be 0btained through reason.Without reason，there is no knowledge，and thus no survival。
You must recognize reality and act in accordance with it in order t0 be successful.To the extent that you use reason as your method of judgment in knowledge and action，you will survive and flourish .If you ignore or escape form. reality you will suffer and die.
It is very important t0 note that survival by reason requires the freedom to act according t0 your reason.That is why people d0 not develop well in the control of others，and can not survive when they are subject t0 foree that destroys their ability to act on reason.

The history of ice cream is amystery. No one knows exactly how and when people began to eat it. There is onestory that the Roman emperor Nero (A.D. 37—68) sent slaves to the mountains tobring back snow. The snow was served to him sweetened with honey and fruit pulp.Marco Polo (1254—1324) tasted flavored ices, too, during his famous travels inthe Far East. He brought the recipes back toItaly.
Recipesfor ices spread fromItalyto the rest of Europe in the 1500’s. The chefs of kings constantly experimentedwith new combinations to please their masters, and at some point cream andbutter were added to the recipes for ice. The new dish was called cream ice.Cream ice, molded into amusing shapes, began to be served on the tables ofkings across Europe. Louis XIV (1638—1715)surprised his court with a dessert of eggs in cups of silver and gilt. Theeggs, of course, were really cream ice.
Graduallycream ice took the name it has today. One of the earliest advertisements forice cream was put in a New Yorkpaper in 1786. The ad announced that “Ladies and gentlemen may be supplied withice- cream every day at the City Tavern by their humble servant, Joseph Crowe.”But ice cream was still not an everyday event. It was usually presented infancy shapes at the end of dinner parties. Policy Madison (1768—1849) was famous for herimaginative dinners, and she was the first to serve ice cream at the WhiteHouse. When her guests came into the dining room, they found a table coveredwith delicious dishes, and in the center of the table, a huge mound of pink icecream on a silver platter.
Icecream was such a delicacy because it was so hard to make. At first it wasbeaten and then shaken by hand in a pan of salt and ice until it became firm. Afreezer that was cranked by hand was developed around 1846. Making ice creamwas still a chore, but cranking the freezer was much easier and faster thanshaking the mixture in a pan.
“Icecream socials” became a popular way to entertain friends. Everyone helped turnthe crank of the freezer, and homemade peach or strawberry ice cream was thereward. The development of the continuous freezer in the 1920’smade the manufacture of ice cream very quick and economical. It soon was easierto buy packaged ice cream than to make it at home. Eskimo pies and popsiclesbegan to be sold at the same time.
Possiblyice cream cones began with the World’s Fair in 1893. Vendors there sold FriedIce Cream. The ice cream was covered with a fritter batter and then quicklydipped in very hot lard or olive oil. Putting the ice cream in an alreadyprepared cone was the next step. Today there are many novelty products, fromfrozen drumsticks to ice cream pies.
