Founded in 1966，Seacamp，the first program dedicated to the education of youth in marine(海洋的) sciences，is the result of a cooperative effort of parents，scientists，businessmen and camp leaders.Preservation practices and a respect for the marine environment are the philosophy of the Seacamp.
Seacamp’s tropical marine location in the lower Florida Keys enables it to offer a truly unique marine science program.This program is the heart of Seacamp.Young scientists participate in a variety of courses under the guidance of academically trained marine science instructors and biologists.All science activities include studies in both the field and the laboratory.Each session,140 to 160 campers come to Seacamp，mostly from the US，but also from across the world.There are about 30 international campers each summer from an average of twelve countries.Many Seacamp program graduates have gone on to careers as environmental educators and marine scientists.
One of Seacamp’s unique aspects is that campers create their schedules.In addition to science classes，campers choose from a variety of programs to ensure that there is something interesting and exciting for everyone.Campers interested in journalism may work on the camp newspaper，SEASCOPE，which is published periodically during camp sessions.Arts activities are also included.Photography allows campers to take home memories of friends，wildlife，and underwater experiences.
Seacamp teaches the fun and skills of sailing.It’s an excellent way for future marine scientists to become familiar with the winds，tides and currents that are of primary concern in oceanography.Basic Red Cross certification is offered to beginners in sailing.The Red Cross course in advanced lifesaving is taught at Seacamp.The course is designed to increase the campers’ ability to recognize and avoid dangerous water conditions and practices and to use selfrescue skills to get out of dangerous situations.
Parents may bring campers by car to Big Pine Key.Counselors(辅导员) also meet participants at the Miami International Airport on the opening day of camp and accompany them to Big Pine Key on a bus.The fee for roundtrip service is $90.To join the Seacamp adventure，interested campers should contact Seacamp for an application.

While learning the science lessons，I used to get a doubt—why ear，nose，tongue and eyes should be called as special senses？The basic reason is that these are the channels through which we maintain contact with the surroundings.Though apparently it may feel like these are individual sensory organs，they do show some connectivity.Interestingly，our hearing is less sharp after we eat a heavy food.Isn’t it good for a sound nap after a stomachfull meal？That does not mean we go deaf after a meal，but the hearing pitch(强度) does change after a heavy meal.
We usually give credit of the taste to our tongue，but do you know that unless saliva(唾液) dissolves something，our tongue cannot recognize the taste of the food eaten.Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds present on the tongue.Try_to_dry_off_your_tongue_and_mouth_with_a_tissue_paper_and_then_taste_something.
Women are much better smellers than men.They are born with this characteristic ability and can correctly pinpoint the exact fragrance of the sample.We all can store almost 50,000 different scents(气味)，which are strongly tied to the memories.
Pupils(瞳孔) do not respond to light alone，but to the slightest bit of noise around too.Thus surgeons，watchmakers and those professionals who have to perform a much delicate job do prefer to have a soundfree environment.Even a small noise can dilate(扩大) their pupils，change the focus and blur(使模糊) their vision.If you do not wear glasses or contact lens due to having a 6/6 vision，you are just among the one third of the human population.It is now statistically proved that only one third of the population has perfect vision，rest all are either wearing glasses or are trying to read with a compromised vision.
Each and every one of us has a particular or individualistic or characteristic smell，which is unique to us，except for the identical twins.This smell is very subtle(微妙的) yet can be sensed even by a newborn.It may be due to this scent that the newborn recognizes the presence of his parents around.Many of us can pinpoint the smell of our significant friends and colleagues.A significant part of this phenomenon is guided by genetics but it is also modified by the environment，diet and personal hygiene.This all together creates the unique chemistry that is individualistic for each person.
小题1:We can learn from Paragraph 1 that ________.| A．after a full meal our hearing is as good as before | | B．all sensory organs are connected and can be exchanged | | C．sensory organs’ functions can never be changed for their particular character | | D．we feel and learn about the world around us through our eyes，ears，nose and tongue |
小题2:What is the text mainly about?| A．The functions of sensory organs. | | B．The connectivity of sensory organs. | | C．A newborn’s senses of the sensory organs. | | D．The differences of senses between women and men. |
小题3:What does the author mean by the underlined sentence in Paragraph 2?| A．Our tongues can’t be dried while eating something. | | B．If your tongue is dried without any saliva on it，it will not work. | | C．A tissue paper is the only thing that can be used to dry our tongues. | | D．If your tongue is dried with a tissue paper，it may work as well as before. |

How far would you be willing to go to satisfy your need to know？Far enough to find out your possibility of dying from a terrible disease？These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的) tests，for everything from baldness to breast cancer，and the list is growing.Question is，do you really want to know what might eventually kill you？For instance，Nobel Prizewinning scientist James Watson，one of the first people to map their entire genetic makeup，is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green，a Harvard geneticist.
“Every ache and pain，” Smith suggested，could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease，then every time you can’t find your car in the parking lot，you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would，for lack of a better medical term，freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact，most people think they can handle it.People who ask for the information usually can handle the information，good or bad，said Green.

Scientists discovered 163 new species in Southeast Asia’s Greater Mekong region last year，but all are at risk of extinction due to climate change，the WWF said in a report released Friday.
The newly discovered creatures include a birdeating frog with fangs (毒牙)，a bird that would rather walk than fly and a gecko (壁虎) whose alien appearance inspired the report’s title of “Close Encounters”，the conservation group said.
The report was released ahead of major UN talks on climate change in Bangkok next week，which are being held before a makeorbreak summit in Copenhagen this December.
“Some species will be able to adapt to climate change，and many will not，potentially resulting in massive extinction，” Stuart Chapman，director of the WWF Greater Mekong program，said in the report.“Rare and endangered species like those newly discovered are especially vulnerable (易受伤害的) because climate change will further shrink their already restricted habitats，” he said.
“The new discoveries in 2010 include 100 plants,28 fish,18 reptiles,14 amphibians,2 mammals and a bird，”the WWF report said.The area spans Cambodia，Laos，Myanmar，Thailand，Vietnam and China’s Yunnan Province.
“Among the new species is the birdeating fanged frog，which remains hidden in a protected area of Thailand despite the fact that scientists are studying there for 40 years，” the report said.
The tigerstriped pit viper was discovered accidentally on an island off the coast of Vietnam when a scientist was looking for a lizard and his son pointed out that his hand was on a rock right next to the snake’s fangs.“We caught the snake and the gecko and they both proved to be new species，” researcher Lee Grismer of La Sierra University in California was quoted as saying in the report.The leopard gecko，found on another Vietnamese island，has the coloring of a leopard and bizarre orange，catlike eyes and thin legs.
The Greater Mekong region has proved a rich area for scientists.The WWF said in December 2010 that it had found 1,068 new species there between 1997 and 2009.
小题1:What is special about the newly discovered bird?| A．It usually walks. | | B．It likes walking and flying. | | C．It can eat other birds. | | D．It can eat frogs. |
小题2:Stuart Chapman believes that________.| A．most of the newly discovered species can adapt to climate change | | B．climate change can cause massive extinction of the newly discovered species | | C．the newly discovered species are not so vulnerable to climate change | | D．many species have already died out because of climate change |
小题3:When Lee Grismer discovered the tigerstriped pit viper，he probably felt________.| A．frightened | B．disappointed | | C．excited | D．puzzled |
小题4:What does the passage mainly tell us?| A．The Greater Mekong region is a rich area for scientists. | | B．Many rare species remain to be discovered in the Mekong region. | | C．Scientists have discovered many new species in the Mekong region. | | D．Climate change threatens Mekong new species. |

Plastic is one of the most important technological discoveries of the 20th century.However，it may soon be replaced.The new development—liquid wood—can replace plastics in all branches of modern industries.
Plastic as a material enjoys the biggest demand in the modern world，but it does have a number of drawbacks.First and foremost，plastic isn’t recyclable.Secondly，it contains toxins (毒物) helping develop cancerous diseases.Finally，it’s made of oil and oil reserves aren’t endless.
The liquid wood technology is likely to replace plastic and provide mankind with new materials for many years ahead.Norbert Eisenfreich，a senior researcher at the Faunhofer Institute for Chemical Technology (ICT) in Germany，said that arboform，the new material，is made of lignin (木质素)，which can be obtained from soft tissues of wood.Once mixed with several other materials，it turns into solid and nontoxic alternative for plastics.
ICT team leader Emilia Regina InoneKauffmann said the woodworking industry separates wood into three basic components，including lignin.Lignin isn’t used for the production of paper.Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded (铸型)．
When solid，arboform looks like plastic and possesses the qualities of polished wood.It can be used for the production of any items.Arboform is already used for the production of car parts which require extra strength.In addition，liquid wood can be recycled repeatedly.The material preserved all of its qualities even if it’s reprocessed ten times.
However，the new invention doesn’t enjoy an extensive use due to the high content of sulphur (硫) in it.German researchers are sure to reduce the amount of sulphur by 90 percent very soon to make arboform usable for home needs.
小题1:According to the passage，plastic________.| A．plays a big role in the modern world | | B．helps to protect our environment in some way | | C．has been replaced by the newly discovered material | | D．helps us to reduce the use of petrol |
小题2:What’s the advantage of arboform over plastics?| A．It is easily made from natural oil. | | B．It is more widely used in household. | | C．It is recyclable and friendly to the environment. | | D．It contains no poisonous materials. |
小题3:It can be concluded that German researchers will focus their future work firstly on________.| A．the material’s extensive use | | B．the content of sulphur in arboform | | C．the production cost of arboform | | D．the qualities of liquid wood |
小题4:The main purpose of the passage is to________.| A．advertise the new material—arboform | | B．introduce liquid wood which will replace plastic | | C．advertise new products made of arboform | | D．show readers how to produce arboform |
