Citizen Scientists

Understanding 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 specific

research 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 climate
changes."

In"All that's needed to become one…（Paragraph 2)",what does the word"one"stand for?
A:A citizen journalist.
B:A citizen scientist?
C:A scientist.
D:A citizen.

答案：B
解析：

短文第一段提到科学家们不可能观察每一个地方的气候变化的现象，所以邀请普通人 为他们观察、收集信息。
短文第二段讲到，平民科学家运动鼓励普通人根据自己的兴趣来观察某一个特定的方 面，并把他们的观察结果发送到一个巨大的数据库来供专业科学家研究。结合选项，可知答案 为B。
短文第二段最后一句话的后半部分“所要做的仅仅是每天或每周抽出几分钟的时间来 收集数据并发送到数据库”可知，"one”是针对citizen scientist来说的。
全文都在讲述普通人参与科学项目的研究，只有A选项不符合题意。其他选项都能在 文中找到。
短文最后一段指出，通过收集数据，我们就能够估算出气候变化对植物和生物群落会 有怎样的影响。所以选D。第5部分：补全短文

第6题：

According to Federal health officials ,the fact that more West Nile cases have been reported indicates that

[A] more states are affected.

[B] the average age dropped drastically.

[C] health officials are more alert to the disease.

[D] the epidemic season began a month earlier.


正确答案：C
52.C 【精析】该题为细节题。第二段第四句“Federal. health officials are still trying to figure out why, but say they may be finding more West Nile precisely because they're on the lookout for it.”中的“be on the lookout for something”意为“注意，留心，警戒”，由此我们知道，联邦公共卫生官员仍然在寻找病毒蔓延的原因，但是认为因为他们对病毒的警惕性高，因此才可能会发现更多的感染者。故只有C项的表述正确。

Cloning（克隆）:Future Pertect?

1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish
scientists reported that they had managed to clone a sheep named Dolly in 1997,research
into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to
create two identical calves（牛犊）using cloning technology. A mouse has also been
cloned successfully.But the debate over cloning humans really started when Chicago
physicist Richard Seed made a surprising announcement:"We will have managed to clonen
a human being within the next two years."he told the world.
2 Seed's announcement provoked a lot of media attention,most of it negative.In Europe,
nineteen nations have already signed an agreement banning human cloning and in the U.S.
the President announced:"We will be introducing a law to ban all human cloning and many
states in the U.S. will have passed anti-cloning laws by the end of the year."
3 Many researchers are not so negative about cloning.They are worried that laws banning
human cloning will threaten important research.In March,The New England
Joumal of
Medicine called any plan to ban research on cloning humans seriously mistaken.Many
researchers also believe that in spite of attempts to ban it,human cloning will have become
routine by 2010 because it is impossible to stop the progress of science.
4 Is there reason to fear that cloning will lead to a nightmare world?The public has been
bombarded（轰炸）with newspaper articles , television shows and films , as well as
cartoons.Such information is often misleading,and makes people wonder what on earth
the scientists will be doing next.
5 Within the next five to ten years scientists will probably have found a way of cioning
humans.It could be that pretty soon we will be able to choose the person that we want our
child to look like.But how would it feel to be a clone among hundreds,the anti-cloners
ask. Pretty cool , answer the pro-cloners（赞成克隆的人）.

Within ten years scientists will probably have______.
A:the nucleus of a cell
B:cloned human beings
C:a human being in two years
D:a law to ban human cloning
E:a report on human cloning
F:heavy media coverage

答案：B

Passage Two

Questions 26 to 30 are based on the following passage.

Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition，man can catch the disease from animals. In fact，a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom，a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.

It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.

Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig，for example，to produce a new strain which is transmitted to man.

According to the passage，scientists have discovered that influenza viruses______.

A. cause ill health in wild birds

B. do not always cause symptoms in birds

C. are rarely present in wild birds

D. change when transferred from animals to man

_________63

答案：C
解析：
空格后的句子表明，生态学家正向公民科学家寻求帮助，可推测出每个地方不可能都有生态学家。故此处应选择A项。 everywhere每个地方；anywhere任何地方（通常用于疑问句或否定句）;somewhere某些地方；nowhere任何地方都不。
此处表示：因为世界上有很多地方，但科学家的数量却不足，所以他们才寻求帮助。所以选择D项。if如果，倘若；although尽管；when当……的时候；because因为。
气候变化的迹象需要人们进行“观察”。give给，给予；show展示；develop发展，开发； observe观察，观测。
结合上下文可知，公民科学家运动鼓励一般人观察非常具体的研究对象。special特殊的；professional专业的；skillful熟练的；ordinary普通的，一般的。
send…to…是固定搭配，表示“把……送往……”，符合题意。
公民科学家帮助搜集数据，为数不多的气候学家就可以分析大量的数据。空格处应该是在强调数据量的庞大，因此选择D项。small小的，少的limited有限的simple简单的，朴素的large大的，大规模的。
空格所在的句子把公民记者与公民科学家进行比较，表明他们的作用相似。much like 表示“就像……一样”，其中much修饰like，符合题意。very like与……很像，但不能用在句首，因此排除A项like与as都有“像……一样”的意思，若连用则意思重复，因此排除C项； many是形容词，不能修饰介词like，因此排除D项。
第二段最后一句表明，要想成为公民科学家中的一员，需要做的全部事情就是每天或每周留出几分钟来搜集并发送数据。all全部，所有；any任何；some一些，某些；most大多数，大部分。
根据第二段第三句可知，公民科学家搜集完信息后要将信息发往一个巨大的数据库，供专业科学家进行分析，所以此处选用send(送往，发送）。print打印，冲洗；answer回答；keep 保持，保留。
此处表示被称为国家物候网络的组织，应该用called，表示事物与名称的关系。known 被知道，若要表示“被称为”应用known as ; featured有……的特征；belonged属于，是……的成员；called被称为，被叫作。
这句话的大意是：这个团体最初的努力要依靠科学家和非科学家这类人去搜集花开叶落的信息。alike相似的，一类的（人或物），通常作后置定语；like相似的，一般作前置定语；un-like不同的; likely可能的，有希望的。
本句大意是：花季追踪计划搜集美国各地的植物的生长周期的数据。而且四个选项中唯有data可以与collects（搜集）搭配。point观点，看法；wonder奇迹，惊奇；data数据；interest 兴趣。
本句大意是：参与这一项目的人―这一项目对所有人开放―他们仅仅需要看看周围有什么。common普通的，平常的；suitable合适的；open开放的；strange奇怪的。
don't have to是固定搭配，意思是“无需，不必”，符合题意。want想要；forget忘记；mind 介意。
这句话的大意是：通过搜集数据，我们就能估算出植物和生物群落对气候变化会做出怎样的反应。how表示对方式的提问，用在此处符合题意。wh。谁，用来提问或连接先行词为人的定语从句；before在……之前；since自从，常用来引导时间状语从句，从句常用过去时，主句常用现在完成时。
