The Book of Life
So far, scientists have named about 1.8 million living species（物种）,and that's just a small part of
what probably exists on Earth.With so many plants,animals,and other creatures covering the planet,it can
be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon-to-be-launched Web site mighit help. An international team of researchers has announced the
creation of a Web-based Encyclopedia（百科全书）of Life(EoL).The project aims to catalog every species
on Earth in a single,easy-to-use referenice guide.
To get the encyclopedia started,the creators will use information from scientific databases（数据库）that
already exist. And eventually , in special sections of the site , nonscientists with specialized（专门的）
knowledge will get to join in Bird-watchers,for example,will be able to input which birds they'ye seen and
where.The technology for this kind of tool has only recently become available.
As the EoL develops,you might find it useful for school projects.The site will feature special pages for
kids who are studying ecosystems（生态系统）in their neighborhoods. To make sure the encyclopedia is
accurate,scientists will review much of the information added to it.People who visit the site will be able to
choose to leave out pages that haven't been reviewed.
Another convenient feature of the EoL is that you'11 be able to pick the level of detail you see to match
your interests,age,and current knowledge.If you wanted to learn about bears for a science class report,for
example,you could use the"novice"setting to get basic information about the animals.On the"expert"
setting,on the other hand,you could get much more detailed information about the history,literature,and
exploration of bears.
It now takes years for scientists to collect all the data they need to describe and analyze species.The
creators of the Encyclopedia of Life hope that their new tool will speed that process.

共用题干第三篇No one knows exactly how many disabled people there are in the world,but estimates suggest the figure is over 450 million.The number of disabled people in India alone is probably more than double the total population of Canada.In the United Kingdom,about one in ten people have some disability. Disability is not just something that happens to other people.As we get older,many of us will become less mobile,hard of hearing or have failing eyesight.Disablement can take many forms and happen at any time of life.Some people are born with disabilities.Many others become disabled as they get older. There are many progressive disabling diseases.The longer time goes on,the worse they become.Some people are disabled in accidents. Many others may have disability in the form of a mental illness.All are affected by people's attitude towards them.Disabled people face many physical barriers.Next time you go shopping or to work or visit friends,imagine what would you do if you could not get up steps,or on to buses and trains?What would you do if you could not see where you were going or could not hear the traffic?But there are other barriers:prejudice（偏见）can be even harder to break down and ignorance represents by far the greatest barrier of all.It is almost impossible for the able-bodied to fully understand what the disabled go through,so it is important to draw attention to these barriers and show that it is the individual person and their ability,not their disability,which counts.The key word in Paragraph 4 is__________.A:barriers B:disabledC:disability D:prejudice

共用题干Ecosystem1. The word “ecosystem” is short for ecological（生态的）system. An ecosystem is where living creatures expand within a given area. You can say that an ecosystem is the natural environment where biological organisms（生物）such as plants,animals and humans co-exist in this world. So naturally that includes you and me. Yes,we are all members of an ecosystem!2 .There are different kinds of ecosystems depending on the type of surface or environ-ment. Most are naturally made such as the ocean or lake and the desert or rainforest.Some are man-made or artificial to encourage co-habitation（同居）between living and non-living things in a monitored environment,such as a zoo or garden.3 .Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone. Plants raised in the earth need air and collect sunlight to help them grow. When they grow,the plants and its fruits or flowers eventually become a source of food to animals,microorganisms（微生物）and even hu- mans,of course. Food is then converted to energy for the rest of us to function,and this hap-pens in a never-ending cycle until the living creatures die and break up back in the earth.4 .Ecosystems are the basis of survival for all living things.We depend on plants and ani-mals for food. In order for us to exist,we need to grow and care about other organisms. We also need to care for the non-living things within our environment like our air and water so we can continue living as a population. Since plants,animals and humans are all of various species（物种）,we all play a role in maintaining the ecosystem.5 .To preserve our ecosystems,we should stop using too much energy,which happens when we consume more than our share of resources. Humans should not disturb the natural habitat（栖息地）of plants and animals,and allow them to grow healthily for the cycle to con-tinue. Too many people in a habitat can mean displacement（搬迁）: imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ru- in the environment and cause destruction of existing plants and animals.Plants,animals and humans are all effective in______.A: our share of resourcesB: a biological creatureC: a given areaD: the maintenance of the ecosystemE: the source of foodF: various species

Yes,we are all members of an ecosystem!2 .There are different kinds of ecosystems depending on the type of surface or environ-ment. Most are naturally made such as the ocean or lake and the desert or rainforest.Some are man-made or artificial to encourage co-habitation（同居）between living and non-living things in a monitored environment,such as a zoo or garden.3 .Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone. Plants raised in the earth need air and collect sunlight to help them grow. When they grow,the plants and its fruits or flowers eventually become a source of food to animals,microorganisms（微生物）and even hu- mans,of course. Food is then converted to energy for the rest of us to function,and this hap-pens in a never-ending cycle until the living creatures die and break up back in the earth.4 .Ecosystems are the basis of survival for all living things.We depend on plants and ani-mals for food. In order for us to exist,we need to grow and care about other organisms. We also need to care for the non-living things within our environment like our air and water so we can continue living as a population. Since plants,animals and humans are all of various species（物种）,we all play a role in maintaining the ecosystem.5 .To preserve our ecosystems,we should stop using too much energy,which happens when we consume more than our share of resources. Humans should not disturb the natural habitat（栖息地）of plants and animals,and allow them to grow healthily for the cycle to con-tinue. Too many people in a habitat can mean displacement（搬迁）: imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ru- in the environment and cause destruction of existing plants and animals.To protect our ecosystems we should not use more than______.A: our share of resourcesB: a biological creatureC: a given areaD: the maintenance of the ecosystemE: the source of foodF: various species

共用题干第三篇Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle events一 flowering,the appearance of leaves and the first frog calls of the spring一all around the world.But ecologists can't be everywhere so they're turning to non-scientists,sometimes called citizen scientists,for help.Climate scientists are not present everywhere.Because there are so many places in the world and not enough scientists to observe all of them,they're asking for your help in observing signs of climate change across the world.The citizen scientist movement encourages ordinary people to observe a very specificresearch interest一birds,trees,flowers budding,etc.and send their observations to a giant database to be observed by professional scientists.This helps a small number of scientists track a large amount of data that they would never be able to gather on their own.Much like citizen journalists helping large publications cover a hyper-local beat,citizen scientists are ready for the conditions where they live in.All that's needed to become one is a few minutes each day or each week to gather data and send them in.A group of scientists and educators launched an organization last year called the National Phenology Network."Phenology"is what scientists call the study of the timing of events in nature.One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing eveiy year.The program,called Project BudBurst,collects life cycle data on a variety of common plants from across the United States.People participating in the project一which is open to every- one一record their observations on the Project BudBurst website."People don't have to be plant experts一they just have to look around and see what's in their neighbor- hood,"says Jennifer Schwartz,an education consultant with the project."As we collect these data,we'll be able to make an estimate of how plants and communities of plants and animals will respond as the climatechanges."What is the final purpose of Project BudBurst?A:To study when plants will have their first buds.B:To find out the types of plants in the neighborhood.C:To collect life cycle data on a variety of common plants from across the United States.D:To investigate how plants and animals will respond as the climate changes.
共用题干第二篇The Book of LifeSo far, scientists have named about 1.8 million living species（物种）,and that's just a small part of what probably exists on Earth.With so many plants,animals,and other creatures covering the planet,it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.A soon-to-be-launched Web site mighit help. An international team of researchers has announced the creation of a Web-based Encyclopedia（百科全书）of Life(EoL).The project aims to catalog every species on Earth in a single,easy-to-use referenice guide.To get the encyclopedia started,the creators will use information from scientific databases（数据库）that already exist. And eventually , in special sections of the site , nonscientists with specialized（专门的） knowledge will get to join in Bird-watchers,for example,will be able to input which birds they'ye seen and where.The technology for this kind of tool has only recently become available.As the EoL develops,you might find it useful for school projects.The site will feature special pages for kids who are studying ecosystems（生态系统）in their neighborhoods. To make sure the encyclopedia is accurate,scientists will review much of the information added to it.People who visit the site will be able tochoose to leave out pages that haven't been reviewed.Another convenient feature of the EoL is that you'11 be able to pick the level of detail you see to match your interests,age,and current knowledge.If you wanted to learn about bears for a science class report,for example,you could use the"novice"setting to get basic information about the animals.On the"expert" setting,on the other hand,you could get much more detailed information about the history,literature,andexploration of bears.It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new tool will speed that process.At the starting stage the EoL will get information from________.A:all the Web sites availableB:the existing scientific databasesC:databases built up by its creators D:nonscientists with specialized knowledge
