　　Thrilled by the successful landing of the rover（漫游者）on Mars，scientists from NASA（the National Aeronautics and Space Administration）have spent the last few days studying data from the robot and working on getting it ready to roll．The Spirit（勇气号）made a landing on Mars．The Spirit made a nerve-racking，but safe，landing on Mars on Sunday on what scientists believe is the rocky bed of an ancient lake that once may have contained life．Just three hours later，the six-wheeled rover began sending black-and-white photos of its surroundings back 170 million kilometres to Earth．The rover sent back a few colour photos on Monday．The scientists were overjoyed by the success．Two of every three past missions to Mars have failed．“It's a big step forward for all humanity．Now we have another rover on another planet，exploring a new world．What more could you ask for？”said Charles Elachi，director of NASA's Jet Propulsion Laboratory．The first images from the Spirit show a flat，wind-damaged surface dotted with small rocks．The scene made scientists eager to send the rover around the planet in search of evidence that the landing site was once covered with water．The US ＄ 820 million project also includes a twin golf cart-sized rover called Opportunity（机遇号），set to land on Mars'other side on January 24．The dozens of initial，low-resolution photos show Spirit landed upright（垂直的），level and facing south on a flat stretch of the hole the scientists believe once contained a lake．It will be about a week before the six-wheeled robot is ready to roll off its lander and move around Mars．Spirit's successful landing has ended the trend of failed missions to Mars．NASA's last attempt to land on Mars，in 1999，ended in failure．Its last successful landing was in 1997，when Path-finder（探险者）carried the tiny Sojourner（旅居者）rover to the surface of Mars．

　　Over the next three months，the robot will use a range of instruments to look for evidence of past water activity in the rocks and soil of the planet．

　　Some people say we need to plant trees in places where rock concerts or conferences are held in order to absorb the carbon dioxide created by the event．This picture shows how trees can help，

　　Photosynthesis（光合作用）

　　①photosynthesis takes place when there is sunlight

　　②Carbon dioxide in air enters the leaves through tiny holes called stomata（气孔）

　　③leaves contain chlorophyll（叶绿素）which traps the sun's energy

　　④Plant's roots gather water from the soil

　　⑤Leaves use chlorophyll and sunlight to change the water and carbon dioxide into food，or sugar，for the plant

　　⑥Oxygen is released into the air

　　Source：Science Net

　　The people below are now traveling in the U．S．，and now looking for a park to visit． After the description of these people，there is information about six American parks AF．Decide which park would be most suitable for the person mentioned in questions 610．There is one extra paragraph about one park which you don't need to use．

　　________1．Lisa is a naturalist．She loves the outdoors and is fascinated with adventure and all types of wildlife．Along with enjoying wildlife she also has a passion for backpacking and hiking．Lisa is also interested in photography and will climb as high as needed to get that great shot．

　　________2．Martin，who is specialized in geography，would like to see a d which is filled with exciting discoveries of facts about the earth movements．He also hopes to observe the changer in rocks due to time and erosion．

　　________3．Kelly，just graduated from university．Her major is archeology．She is interested in ancient finds such as ：fossils of animals and plant life，old pottery and especially things dating back to the prehistoric age．Kelly hopes to unearth something significant so that she can develop her career．

　　________4．Simon is one excitement．He enjoys all out-door sports especially white water rafting．He has been searching for a park that can fulfill his taste for adventure．And at the same time he can appreciate the beautiful sceneries along the way．

　　________5．Chris is looking for something famous perhaps a“superstar”of parks．He is interested in everything from wildlife to earth activities．He hopes he can find a park which can offer the most to him．

　　A．This park is a vast natural museum，and it is recognized as the lowest point in the U．S．All the great divisions of geological（地质的）time，the eras and most of their subdivisions，are represented（描写）in the rocks of the mountains bordering the great valley．These rocks and the land forms tell a story of endless changes in the earth's crust（地壳）-vast depositions，contortions，tilting，alternate rising and lowering，faulting and intense heats and pressures that changed the very nature of some rocks．

　　B．This park protects a large deposit（存放）of fossil（化石）dinosaur bones-remains of the so-called“terrible lizards” that lived millions of years ago．The dinosaurs weren't really lizards，and most of them weren't even terrible．But some of the first dinosaur fossils ever found were huge bones and teeth，very lizard-like except for their size，and so the idea of monstrous lizards was born．Today，many ideas about dinosaurs are changing，and the fossils at this park continue to help us learn more about these fascinating animals．

　　C．With elevations ranging from 8，000 feet in the wet，grassy valleys to 14，259 feet at the weather-ravaged top of Long's Peak，a visitor to the park has opportunities for countless breathtaking experiences and adventures．A large variety of animals will delight wildlife-watchers of all ages．Wildflower-lovers are never disappointed in June and July when the meadows and hillsides are splashed with botanical color．359 miles of trail offer endless opportunities to hikers，backpackers and horseback riders．So far to find 60 peaks rising above 12，000 feet challenge intrepid hikers and climbers．

　　D．The world's largest concentration of natural stone arches is found in this park．Over 1500 of these“miracles of nature”grace the 73，000-acre area．And it is famous for the red arches of Entrada sandstone that occur there in great profusion．A 41-mile round-trip paved road in the park leads to the major sights， including Balanced Rock，Skyline Arch，and the Fiery Furnace．But there are also many other striking rock formations scattered over the park's 73，000 scenic acres．

　　E．Yellowstone is the oldest park in the U．S．park system and is its flagship．Visitors come to experience the park's restless geology；to see grizzlies，gray wolves，and herds of buffalo．Its turbulent（狂暴的）landscape-which remains among the most geologically active lands on the planet，with steam-spewing geysers（间歇温泉），gurgling fumaroles，and frequent earthquakes-was protected as the world's first national park in 1872．Yellowstone and the huge tracts of national-forest land that ring it comprise one of the world's last intact temperate ecosystems-all its major species of plants and animals are still present．

　　F．This park has a canyon 200 miles long and about a mile deep．Along the ride you follow the Colorado River which carved this massive canyon．At times the canyon is from 5 to 15 miles across．The Colorado River continues to shape and gouge its way through the canyon where about 90 species of mammals（哺乳动物）and some 290 species of birds live．River rafting along the Colorado River has different options for people．You can go on long trips with organizations or even take a smooth ride down the river with a picnic style lunch．

　　There are many commonly held beliefs about eyeglasses and eyesight that are not proved to be facts．For example，some people believe that wearing glasses too soon weakens the eyes．But there is nothing to show that the structure of eyes is changed by wearing glasses at a young age．Wearing wrong glasses，however，can prove harmful．Studies show that only children can develop poor eyesight if they have wrong glasses． We have all heard of some of the myths（荒诞的说法）about how eyesight gets bad．Most people believe that reading in poor light causes poor eyesight，but that is untrue．Too little light makes the eyes work harder so they soon get tired and strained（疲劳）．Eyestrain also results from reading too long，reading in bed，or watching too much television．But，although eyestrain may cause some pains or headaches，it does not harm eyesight directly．Nevertheless，proper lighting，when reading or studying，is essential（基本的）to maintain（保持）good eyesight．

　　Another myth about eyes is that they can be transplanted．It is quite difficult to connect an eyeball to a new brain．And it is impossible to transplant a whole eyeball to another person．Only certain parts of the eye can be transplanted now． But if we keep clearing up the myths and learning more about the eyes，some day it may be possible to replace a full ball．

　　Many experts complain that media too often take advantage of the science fiction aspects of nanotech（纳米技术）．Reports of nanotech often refer to K．Eric Drexler's book Engines of creations，which predicts an age full of dominant molecular（分子的）manufacturing and a world without material scarcity．whatever humans need will one day be built cheaply with microscopic self-replicating machines（微细自我复制机）that put atoms together to create copies of anything alive in the world-from trees to human bodies．

　　In fact，the scientific community is deeply divided over whether self-replicating machines are possible．If they are，major dangers could exist．Mr．Drexler himself thought that self-replicating machines could probably go out of control．He writes in his book that man-made “plants”with“leaves no more efficient than today's solar cells could win over real plants，crowding the earth with leaves that are not suitable to be eaten．Tough‘bacteria'could be more competitive than the real bacteria：they could spread everywhere，replicate swiftly，and reduce the earth to dust in a matter of days．”

　　Critics of nanotech have made use of such images，calling for a delay on commercial nanotech until regulations are established．They also point to the possible military uses of nanotech．Bill Joy，the cofounder of Sun Microsystems，wrote a Wired magazine essay in 2000 that if nanotech falls into the wrong hands，it could bring danger to society．

　　Opponents say Mr．Joy is overreacting．“ In a way，calling for bans on research into molecular manufacturing is like calling for delay on faster-than-light travel because no one is doing it，”says Glenn Reynolds，a University of Tennessee law professor．

　　Professor Reynolds says it is a good idea to regulate nanotech，but in ways the government would regulate any products that could be dangerous．Export controls and certification systems for nanotech companies are examples．US lawmakers have put forth four bills on nanotech research and development．

1．Eric Drexler in his book predicts a future world with sufficient material，because________．

[　　]

A．man-made plants could replace real plants and grow more quickly

B．plants produced by nanotech would be as efficient as today's solar cells

C．man-made bacteria would be widespread and capable of self-replicating

D．humans could create copies of anything alive with high technology

2．To call for a delay of commercial nanotech，critics of nanotech make use of________．

[　　]

A．current social problems

B．science fiction descriptions

C．disagreements in the scientific community

D．he fact that no one is doing molecular manufacturing

3．Opponents of Bill Joy would NOT agree to________．

[　　]

A．control nanotech export

B．ban nanotech research to avoid any possible dangers

C．put forth bills on nanotech research and development

D．establish a certification system for nanotech companies

4．Which of the following statements best summarizes the main idea of the passage？

[　　]

A．Nanotech should not be put into wrong use in the military field

B．The government should regulate products that could be dangerous

C．Nanotech regulations should be established in spite of the divided opinions

D．The media should not take advantage of the science fiction aspects of nanotech．

　　Until men invented ways of staying underwater for more than a few minutes，the wonders of the world below the sea were almost unknown．And to make full use of the rich natural resources（资源）underwater was quite impossible．How could air be supplied to divers below the surface（表面）of the sea？There were pictures in the past showing men swimming under the surface with air bags tied to their bodies．A pipe from the bag carried air into the swimmer's mouth．But little progress was made in the invention of diving devices（潜水设备）until 1490，when the famous Italian painter Leonardo da Vinci（莱昂纳多·达芬奇）designed a complete diving suit．

　　In 1819 a German，called Siebe developed a way of forcing air into the head covering by a machine operated above the water．Finally，in 1837 he invented the“hard-hat suit” which was used for almost a century．It had a metal covering for the head and an air pipe attached（连接）to a machine above the water．It also had small openings to remove unwanted air．But there were two dangers to the hard-hat suit．One was a sudden rise to the surface，caused by too great a supply of air．The other was the crushing（挤压）of the body，caused by a sudden dive into deep water．

　　Are you carrying too much on your back to school？Lots of kids your age are． Not only are students in China suffering from the problem，but kids in the United States are puzzled by heavy school bags．

　　Experts are starting to worry that young students are having back and neck problems as a result of school bags being too heavy for them．“It is hard for me to get up the stairs with my bag because it's so heavy，”said Rick Hammond，an 11-year-old student in the US．

　　Rick is among the students who have regular backpacks（背包）with two straps（带子）to carry them，but a number of other students choose rolling back-packs．But even with rolling backpacks，getting upstairs and buses with them is still a problem for kids．Many of them have hurt their knees，backs or necks be-cause of heavy school bags．

　　But how much is too much？Experts say students should carry no more than 10 to 15 percent of their own body weight．Scott Bautch，a Wisconsin back doctor，said kids under 4th grade should stay with 10 percent，but it's also important that older kids don't go beyond（超出）15 percent，because their bones are still growing．

　　Bautch explained that there are other injuries caused by backpacks．“Kids are losing their balance and falling down with these backpacks，” he said．

　　Parents and teachers are starting to tell kids to only take home library books they will be reading in the evening．Some teachers are using worksheets（作业单）or thin workbooks for students to take home．
