Passage Four
Within a large concrete room，Cut out of a mountain on a freezing-cold island just 1,000 kilometres from the North Pole，could lie the future of humanity.
The room is a vault(地下库)designed to hold around 2 million seeds,representing all known varieties of the world’S crops.It is being built to safeguard the world’S food supply against nuclear War,climate change，terrorism，rising sea levels，earthquakes and the collapse of electricity supplies。“If the worst came to the worst，this would allow the world to reconstruct agriculture on this planet，”says Cary Fowler,director of the Global Crop Diversity Trust，an independent international organisation promoting the project.
The Norwegian(挪威的)government is planning tO create the seed bank next year at the request of crop scientists.The ＄3 million vault will be built deep inside a sandstone mountain on the Norwegian Arctic island of Spitsbergen.The vault will have metre-thick walls of reinforced concrete and will be protected behind two airlocks and high-security doors.
The vault’S seed collection will represent the products of some 10，000 years of plant breeding by the world’S farmers.Though most are no longer widely planted，.the varieties contain vital genetic properties still regularly used in plant breeding.
To survive，the seeds need freezing temperatures.Operators plan to replace the air inside the vault each winter,when temperatures in Spitsbergen are around-18℃.But even if some disaster meant that the vault Was abandoned,the permanently frozen soil would keep the seeds alive.And even accelerated global warming would take many decades to penetrate the mountain vault.
“This will be the world’s most secure gene bank，” Says Fowler.“But its seeds will only be used when all other samples have gone for sOme reason.”
The project comes at a time when there is growing concern about the safety of existing seed banks around the world.Many have been criticized for their poor security, ageing refrigeration(冷藏)systems and vulnerable electricity supplies.
The scheme won UN approval at a meeting of the Food and Agriculture Organization in Rome in October 2005.A feasibility study said the facility“would essentially be built to last forever”.

B. as produc of world plant breeding
C.for their valuable genetic properties

答案：A
49.For the seed bank project to be successful，the most important factor is probably______________.

D.The UN financed the Spitsbergen seed bank.
答案：C
Passage Five
Probably the hardest part of setting goals is the first step of actually deciding to take action!The first barrier facing most people is the incorrect assumption that goals are only for business people.The reality is everyone sets goals mentally throughout the day.There are always occasions where something has to be done at a particular time Or in a particular place.Simple examples could be getting up at a certain time in order to be at work，or to meet with a friend for a leisure activity.
The beauty of having goals is the uniqueness.of each one to’the goal setter.
Whether it is personal，financial，business or spiritual，they are all specific to that person and their circumstances.
The most important part initially is to write them down.Having goals mritten down gives you incredible power while helping you to focus on this area.
Aim for something that will stretch you while remaining achievable.If you achieve your goal too easily,it is not high enough to make any significant change in your life and needs to be adjusted.On the other hand，if you consistently miss the goals，re-evaluate，and consider setting them a little lower as you will only get discouraged and probably give up. The aim is to keep growing，and moving into a more satisfactory position for your particular circumstances.
As you obtain the levels that you have set for yourself,always include a small reward at each point.This might only be a small thing in the early days like a meal out or a weekend vacation.
Remember that these changes will not happen overnight and there will be a period of time when nothing seems to be happening.This is why the goals need to be detailed and as specific as possible with a consequence and benefit.
Allow some time on a daily basis to educate yourself on how to make the necessary adjustments in your life.This could include listening to a CD，or reading a book on motivation etc.
A simple method to start with could be one goal in the main areas of life to be achieved in one month,six months,twelve months or five years.Break that down further into a daily,weekly and monthly system.Stay focused and disciplined t0 achieve all that you desire.
