400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(蘚類植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(莖). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔蘚類植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(瀕絕生物保護(hù)區(qū)), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings(論文集)of the National Academy of Sciences.
小題1:Dr La Farge’s research is of great importance to ________.
A.knowing what the plants during the Little Ice Age were like
B.understanding how ecosystems recover from glaciers.
C.regrowing many species that have been destroyed before.
D.figuring out the effects of melting ice caps on moss.

Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.
小題1: The results of the South American experiment         .
A.a(chǎn)re not yet certainB.have proved to be wrong
C.have caused a serious troubleD.a(chǎn)re not important
小題2: The experiment mentioned in this passage was designed to             .
A.make African bees less active
B.make Brazilian bees more easy-going
C.increase the number of bees in Brazil
D.increase the amount of honey in Brazil
小題3: Which of the following may be the cause of the new bees' attacking personalities?
A.Their production of honey.B.Their living environment.
C.Their hard work.D.Their bad temper.
小題4: The last paragraph implies that            .
A.the bees have been driven to Central and North America
B.the bees must be stopped from moving north
C.the bees may bring about trouble in more countries
D.the bees prefer to live in Brazil

Today, the biggest killers stem as much from our lifestyles as from bacteria and viruses.  One of the worst of these is heart disease, and specifically high blood pressure. It’s a slow, but efficient killer that robs many people of what should be the last 10, 20 or 30 years of their lives.
Scientists are claiming that they have now separated unusual ingredients in a rare seaweed discovered by fishermen off the coast of Korea that offer incredible health benefits—including the ability to restore blood pressure to normal levels.
Dr. Haengwoo Lee, a famous biochemist conducted a clinical study on these two ingredients. The first is Seanol, an extremely rare seaweed extract(濃縮物) from Ecklonia Cava that's proven to be 100 times more powerful than any land-based antioxidant(抗氧化劑). That's because it stays working in your body for 12 hours, compared to land-based antioxidants that work for 30 minutes.  "Its secret is its make-up of special chemicals that are a huge 40% fat soluble( 可溶的)," Dr. Lee explains. "Unlike nearly all land-based antioxidants that are water soluble, Seanol's protective compounds can get into things like the fatty tissues of your brain and penetrate(滲透) all three layers of your cells, including the outside, the oil-based cell membranes(細(xì)胞膜), and your DNA." Indeed, Seanol is so powerful, it's the only FDA-approved Ecklonia Cava marine-algae (海藻)  extract in existence.
The second ingredient is Calamarine, a deep-sea omega-3 discovery that delivers 85% more DHA omega-3s to your heart, brain, joints, and eyes. It's known to reduce the problems from tiredness and poor memory, joint pain, mood swings and depression.
With that research in mind, Dr. Lee combined Seanol and Calamarine with a high dose of vitamin D to form  Marine-D3, the newest supplement in the fight against age-related illnesses and high blood pressure.
Dr. Lee found that Calamarine delivers some of the greatest concentration of omega-3s known to science. Combined with Seanol's ability to reduce body inflammation(炎癥), as well as help cells get the nutrients they need to thrive, stay healthy and protected, Marine-D3 is able to boost a body's entire well being.
The makers of Marine-D3 are so confident that you'll see fast dramatic results from this product, that if you aren't happy after two full months, simply return the unused portion and they'll buy it back. They'll even give you ten dollars extra just for giving it an honest try! That kind of faith, combined with Dr. Lee's exhaustive research, shows that Marine-D3 really is a one-of-a-kind product.
小題1:From the first paragraph we can infer that ________.
A.Our lifestyles result from the biggest killers
B.our lifestyles do less harm to our bodies than bacteria and viruses do.
C.High blood pressure left untreated may cause shorter life.
D.Heart disease is incurable.
小題2:What can we know from paragraph 2 ?
A.Fishermen off the coast of Korea have isolated unusual ingredients.
B.Scientists have purified ingredients that can lower blood pressure to normal standard.
C.Scientists discovered a rare seaweed.
D.Scientists have imagined a medicine that treat blood pressure.
小題3:Which is right about Seanol ?
A.According to FDA , Seanol reaches the agreed standard.
B.Seanol can be fat soluble entirely.
C.Seanol is a common seaweed extract fromEcklonia Cava.
D.Seanol's protective compounds can get into all things like the fatty tissues of your brain.
小題4:What do we know about Calamarine?
A. Calamarine is easy to find in the surface of the sea.
B. Calamarine 's ability to reduce body inflammation(炎癥) alone.
C. Calamarine has a low dose of vitamin D and C.
D. Calamarine may relieve you if you feel blue.
小題5:What’s the makers’ attitude toward Marine-D3?
A.pessimisticB.indifferentC.doubtfulD.Optimistic

I got tired of living the life that everybody told me I “should” be living, so one day I decided to start living life in my own ways. Frustrated(挫。﹚ith my job, I came home, put on my shoes, and just started running. It felt so good to be free. That first day I ended up running 30 miles without stopping. Yes, I had rediscovered my old passion ( 酷愛(ài)的事物) — and it felt so good that I set a goal to support myself and my family from my running alone.
I trained hard every day. Since I wanted to be the best I could be, I knew I would have to set some clear goals for myself. A couple of my goals were: run a 135-mile ultra-marathon(超級(jí)馬拉松) across Death Valley, win the Badwater Ultra-Marathon, and run a marathon to the South Pole.
I had no idea how I was going to achieve these goals, but they certainly encouraged me to work hard. Today, I am really grateful to say that I have achieved all of them. Shortly after completing these goals, I set another goal: to run fifty marathons, in fifty states, in fifty days. Nobody had done anything like this before. To be honest, I was not quite sure if I could. But there was only one way to find out…so I just started training and preparing to give it my best try.
I completed that goal one year ago, and it felt great! But for me, life is not all about achieving goals. Sure, it feels good to succeed, but the greatest reward for me was learning more about myself and what I was able to do.
Only by stepping out into the unknown and stretching(使傾注全力) ourselves can we really discover what our true potential(潛能) is。
小題1:Which played an important role in the author’s success?

What if I took that big jump on my bike?What’s the worst thing that could happen if I go out at midnight?Should try smoking?The teen years can play out like a choose-your-own-adventure novel.
Teenagers must act on an endless parade of choices.Some choices.including smoking.Come with serious consequences.As a result, adolescents often find themselves trapped between their impulsive tendencies(-Just try it!)and their newfound ability to make well-informed and logical choices(-Wait, maybe that’s not such a good idea!).
So what makes the teenager’s brain so complex? What drives adolescents-more than any other age group-to sometimes make rash or questionable decisions?
If you have ever thought that the choices teenagers make are all about exploring and pushing limits, you are on to something. Experts Experts believe that this tendency marks a necessary period in teen development.The process helps prepare teenagers to confront the world on their own. It is something all humans have evolved to experience-yes, teens everywhere go through this exploratory period.Nor is it unique to people:Even laboratory mice experience a similar stage during their development.
For example,laboratory experiments show that young mice stay close by their mothers for safety. As mice grow.their behavior does too.“When they reach puberty,they’re like,‘I’m gonna start checking out how this environment looks without my mom,…explains Beatriz Luna,of the University of Pittsburgh.
As a developmental cognitive neuroscientist,Luna studies those changes that occur in the brain as children develop into adults.She and other researchers are showing how the teen experience can lead to powerful advantages later in life.Take mice again:Young mice that explore most tend to live longest——that is,unless a cat eats them,Luna adds.
小題1:What is the best title for the text?
A.Teenagers make endless choices

Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles(裝置). Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星細(xì)菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(萬(wàn)億). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?
小題1:Which of the following is TRUE according to the “A welcoming planet” part?
A.Mars is a little bigger than Earth.
B.There are flowing rivers on Mars.
C.People haven’t been to Mars so far.
D.Scientists have discovered signs of life on Mars.
小題2:Which of the following can best fill in the blank in the passage?
A.Living in space.B.Limited resources.
C.Extreme conditions.D.Interesting challenges.
小題3:By “Tiny dangers” the author means ________________.

B.people won’t be in any danger
C.it’s difficult for people to realize the danger
D.the danger may be caused by very small things
小題4:Which may cause the biggest danger?
A.Martian germs may be different from those on Earth.
B.Martian germs may be brought back to Earth.
C.People may carry germs to Mars.
D.There may be germs on Mars.

Baekeland and Hartmann report that the " short sleepers"  had been more or less average in  their sleep needs until the men were in their teens. But at about age 15 0r so, the men voluntarily  began cutting down their nightly sleep time because of pressures from school, work, and other  activities. These men tended to regard their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these "short sleepers" appeared ambitious, active, energetic and cheerful. They  stuck to their opinions, and were very sure about their job choices..They often held several jobs at  once, or worked full-or part-time while going to school. And many of them had a strong urge to appear "normal"  or " acceptable"  to their friends and colleagues.
When asked to remember their dreams,  the " short sleepers"  did poorly. More than this,  they seemed to prefer not remembering. Similarly, their usual way of dealing with psychological problems was not to admit that the problem existed, and then to keep busy in the hope that the trouble would go away.
The sleep patterns of the " short sleepers"  were similar to,  but less extreme than,  sleep patterns shown by many mental patients categorized as manic  (躁狂者).
The "long sleepers" were quite different indeed. Baekeland and Hanmann report that these young men have been lengthy sleepers since childhood. They seemed to enjoy their sleep, protected it, and were quite concemed when sometimes they didn't have their desired 9 hours of nightly bed rest. They tended to remember their dreams much better than the  " short sleepers".      Many of the "long sleepers" were shy, anxious, quiet, nervous, passive, mildly depressed, and unsure of themselves ( particularly in social situations) . Several openly stated that sleep was an escape from their daily problems.
小題1:From the passage, we can leam that           .
A."short sleepers" need less sleep by nature
B."long sleepers" sleep a longer period of time during the day
C.many "long sleepers" preserve their sleeping habit formed during their childhood
D.many " short sleepers" have to reduce their nightly sleep time because of busy work
小題2:Many "short sleepers" are likely to hold the view that _____.
A.sleep is a good way to escape from the reality
B.sleep is not so important as their daily activities
C.sleep affects their judgment on some important things
D.sleep is the best way to deal with psychological troubles
小題3: It can be learned from the passage that the"short sleepers" _____.
A.do not know how to relax properly
B.a(chǎn)re more unlikely to run into mental problems
C.a(chǎn)re full of energy even under the pressures of life
D.often pay little attention to the consequences of inadequate sleep
小題4: When sometimes they cannot enjoy adequate sleep, the "long sleepers" might ______.
A.a(chǎn)ppear disturbedB.become energetic
C.feel dissatisfiedD.be extremely unhappy
