The Mysteries of Nazca
In the desert of Peru,300 kilometers from Lima,one of the most unusual artworks in the world has
mystified（迷惑）people for decades._________ (46 ) But from high above,these marks are huge images
of birds,fish,seashells,all beautifully carved into the earth.
The Nazca lines are so difficult to see from the ground that they weren't discovered until the 1930s,
when pilots spotted them while flying over the area. In all,there are about 70 different human and animal
figures on the plain,along with 900 triangles,circles,and lines.
Researchers have figured out that the lines are at least 1,500 years old,but their purpose is still a
mystery.__________(47)However,it would probably be very tricky to land a spaceship in the middle of
pictures of dogs and monkeys.
In the 1940s,an American explorer named Paul Kosok suggested that the drawings are a chronicle（记
录）of the movement of the stars and planets._________(48)Later,an astronomer tested his theory with
a computer,but he couldn' t find any relation between the lines and movements in space.
Another explanation is that the lines may have been made for religious reasons.British researcher Tony
Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by
the side of the road.It's possible that in the past,the lines of Nazca were created for a similar purpose.
_________(49)But the local people have never constructed anything this big.
Recently,two other scientists,David Johnson and Steve Mabee,have speculated that lines could have
been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every year.
While Johnson was searching for ancient water sources in the area,he noticed that some waterways built by
ancient people were connected with the lines.Johnson believes that the Nazca lines are a giant map of the
underground water in the area._________(50)

Your Bean Steak (素肉排), Sir!What sort of food are we likely to be eating in the year 2000?Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed ( 分配 ).This does not mean, however, that our diet ( 饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.1.Most people believe that food supplies in the future().A、will become a very serious problemB、will be the same as they are todayC、will be enough in quantity but not good in qualityD、will be much better than they are today2.The reason why people are hungry in today's world is().A、poor farming methods and bad distributionB、slow growth of food productionC、food shortages all across the worldD、fast rising population3.The word "bacon" in Line 5, Para.3 most probably is().A、a kind of "meat" made from grainB、meat made from fishC、food for fishD、meat made from pigs4.The word "particular" in Line 4, Para.4 means().A、specialB、choosyC、detailedD、very exact5.The title of this passage suggests that().A、food in the future will be tastelessB、there will be worldwide food shortagesC、diet in the future will be very differentD、science is making rapid progress

Where Has the Salt Come from?Every now and then,we meet a fact about our earth that makes us feel strange and no answer for the fact has yet been found.Such a fact is the existence of salt in the oceans. How did it get there?We simply do not know how the salt got into the ocean!We do know,of course,that salt is water-soluble,and so passes into the oceans with rainwater.The salt of the earth's surface is constantly being dissolved（溶解）and is passing into the ocean.But we do not know whether this can explain the huge quantity of salt in oceans.If all the oceans were dried up,enough salt would be left to build a wall 180 miles high and a mile thick. Such a wall would reach once around the world at the Equator（赤道）!The common salt that we all use is produced from seawater or the water of salt lakes, from salt springs（源泉）and from deposits of rock salt. The concentration（浓度）of salt in seawater ranges from about three percent to three-and-one-half percent. The Dead Sea, which covers an area of about 340 square miles,contains about 11,600,000,000 tons of salt!On the average, a gallon（加仑）of seawater contains about a quarter of a pound of salt.The beds of rock salt that are found in various parts of the world were all originally formed by the evaporation（蒸发）of seawater millions of years ago. It is believed that the thick rock-salt deposits were formed after about nine-tenth of theY volume of seawater had been evaporated.Most commercial salt is obtained from rock salt.The usual method is to drill wells（井） down to the salt beds. Pure water is pumped down（抽进去）through a pipe. The water dissolves the salt and it is forced through another pipe up to the surface.The author is sure that the dissolved salt from the earth's surface is the only source of the huge quantity of salt found in oceans.A:Right B:Wrong C:Not mentioned

Mt. Desert IslandThe coast of the State of Maine is one of the most irregular in the world.A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles.If you followed the coastline between these points,you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline._________(46)At that time,the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier（冰川）descended , however , it expendedenormous force on those mountains,and they sank into the sea.As the mountains sank,ocean water charged over the lowest parts of the remaining land,forming a seriesof twisting inlets and lagoons（咸水湖）.The highest parts of the former mountain range,nearest the shore, remained as islands._________(47)Marine fossils found here were 225 feet above sea level,indicating thelevel of the shoreline prior to the glacier.The 2,500-mile-long rocky coastline of Maine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited,but many are home to thriving communities.Mt. Desert Island is one of the largest,most beautiful of the Maine coast islands.Measuring 16 miles by 12 miles.Mt.Desert was essentially formed as two distinct islands._________(48)For years,Mt. Desert Island,particularly its major settlement,Bar Harbor,afforded summer homes for the wealthy.Recently though,Bar Harbor has become a rapidly growing arts community as well.But,the best part of the island is the unspoiled forest land known as Acadia National Park.Because the island sits on the boundary line between the temperate（温带）and sub-Arctic zones , the island supports the plants and ani- mals of both zones as well as beach , inland , and alpine（高山的）plants. _________( 49 ) The establishment of Acadia National Park in 1916 means that this natural reserve will be perpetually available to all people,not just the wealthy.Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping,cycling,and boating. Or they may choose to spend time at the archeological museum,learning about the Stone Age inhabitants of the island.The best view on Mt.Desert Island is from the top of Cadillac Mountain._________(50)From the sum- mit,you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty created by a retreating glacier._________(49)A:This mountain rises 1,532 feet,making it the highest mountain on the Atlantic seaboard.B:It is split almost in half by Somes Sound,a deep and narrow stretch of water,seven miles long.C:The wealthy residents of Mt.Desert Island selfishly kept it to themselves.D:Mt. Desert Island is one of the most famous of all the islands left behind by the glacier.E:The term comes from the activity of the ice age.F: It also lies in a major bird migration lane and is a resting spot for many birds.

New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat.

Despite the most pains-taking research， no one has yet found the answer， One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times， and this makes it easier for cold viruses to be passed on.No one has yet found a cure for the cold.There are drugs and pain suppressors such as aspirin， but all they do is relieve the symptoms.Arctic explorers may catch colds when ____.A
