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.

Eating Potatoes Gives Your Immune System a Boost
Eating potatoes is not only good for bowel health,but also for the whole immune system,espe- cially when they come in the form of a potato salad or eaten cold.In a study on an animal model, researchers in Spain found that pigs fed large_________(51)of raw potato starch(RPS)not on-ly had a healthier bowel,but also decreased levels of white blood cells,________(52)as leuco- cytes and lymphocytes in their blood.White blood cells are produced as a_________(53)of in-fEammation or disease,generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect,a generally more_________(54)body.The reduction in leucocyte levels was about 15 percent.Lower lymphocyte levels are also indicative of_________(55)levels of in-flammation,but the observed reduction in both lymphocyte density_________(56)lymphocyte apoptosis is surprising.
In_________(57)was the longest study of its kind,pigs were fed RPS over 14 weeks to _________(58)the effect of starch on bowel health.“The use of raw potato starch in this experi-ment is_________(59)to simulate the effects of a diet high in resistant starch,”said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,Spain.
Humans do not eat_________(60)potatoes,but they do eat a lot of foods that contain resist-ant starch,such as cold boiled potatoes,legumes,grains,green bananas,pasta and cereals.About 10 percent of the starch eaten by human is resistant starch—starch that is not_________(61)in the small intestine and so is shunted into the large intestine where it ferments.Starch consumption is thought to reduce the_________(62)of large bowel cancer and may also have an effect on irritable bowel syndrome(IBS).
Immunology expert Lena Ohman' s team_________(63)found that the overall lymphocyte levels do not vary for IBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of lBS being_________(64)least partially an inflammato- ry disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interest-ing,and a diet of resistant starch may be worth_________(65)in lBS patients.Ohman is cur-rently at the Department of Internal Medicine,Goteborg University,Sweden.The study is pub-lished in the Journal Chemistry and Industry,the magazine of the SCI.

Searching for Smiles
1 Ask most people anywhere in the world what they want out of life and the reply will
probably be:"to be happy."Ed Deiner,an American psychology professor,has spent his
whole professional life studying what makes people happy,comparing levels of happiness
between cultures and trying to find out exactly why we enjoy ourselves.
2 Many people would say that this question does not need an answer.But Professor Deiner
has one anyway."If you're a cheerful,happy person,your marriage is more likely to last,and
you're more likely to make money and be successful at your job.On average,happy people
have stronger immune(免疫的)systems, and there is some evidence that they live longer."
3 So who are the world's happiest people?It depends on how the word is defined.There
is individual happiness,the sense of joy we get when we do something we like.But there is
also the feeling of satisfaction we get when we know that others respect us and approve of
how we behave.According to Professor Deiner,the Western world pursues individual
happiness while Asia prefers mutual satisfaction.
4 "In the West, the individualistic(個(gè)人主義的)culture means that your mood matters
much more than it does in the East.People ask themselves,what can I do that's fun or
interesting?They become unhappy when they can't do any of these things.If you ask
people from Japan or China if they are happy,they tend to look at what has gone wrong in
their lives.If not much has gone wrong,then they are satisfied."
5 People from Spain and other Spanish-speaking countries had the happiest culture,Professor
Deiner found."The biggest cultural difference is to do with pride and shame.Hispanic(西班牙
語(yǔ)言的)cultures report much more pride and much less shame than others."
6 Income also made a big difference to people's happiness,but only at the lowest levels.
Average income earners in the US were much happier than people in poverty.But
millionaires were only a little bit happier than people on average incomes.It seems that
money makes us happy when we have enough to feel secure.
7 But can we be too happy? "You get people who are actually happy,but they think
happiness is so important that they try to be even happier.This desire to be always happy is
a product of individualism,where the emphasis is on you individually,your emotions and
feeling good.People can end up feeling unhappy because ordinary happiness is not good
enough for them."
Paragraph 5_________
A:Happiest Culture
B:An Unhappy Person
C:Definition of Happiness
D:Cultural Differences in Happiness
E:Reasons to Be Happy
F:Individual and Ordinary Happiness
