Can software bring dead tongues back to life? Probably yes.
A computer algorithm（計算程序）works almost as well as a trained linguist（語言學(xué)家） in reconstructing how dead "protolanguages" would have sounded, says a new study.
"Our computer system is doing a basic job right now," says Alex Bouchard-Côté, an assistant professor in the department of statistics at the University of British Columbia and lead author of the paper describing the algorithm. But the program does a good enough job that it may be able to give linguists a head start, the statistician added.
For centuries, scholars have reconstructed languages by hand: looking at the same word in two or more languages and making educated guesses about what that word's "ancestor" may have sounded like. For example, the Spanish word for man （"hombre"） and the French word for man （"homme"） developed from the Latin word "homo." The way linguists compare words from descendant（后代）languages to reconstruct the parent language is called, appropriately, the comparative method.
The early 19th-century linguist Franz Bopp was the first to compare Greek, Latin and Sanskrit using this method. Jacob Grimm, one of the Brothers Grimm of fairy tale fame, used the comparative method to show how Germanic languages developed from a common ancestor.
The difference between that and Bouchard-Côté's program, the statistician says, "is we do it on a larger scale." As a proof of concept, Bouchard-Côté fed words from 637 Austronesian languages （spoken in Indonesia, the Philippines, Malaysia and more） into the new algorithm, and the system came up with a list of what the ancestor words of all those languages would have sounded like. In more than 85 percent of cases, the automated reconstruction came within one character of the ancestor word commonly accepted as true by linguists.
The algorithm won't replace trained human linguists, but could speed up language analysis.
Using a computer to do large-scale reconstruction offers another advantage. Bouchard-Côté says, “With big data sets, you can really start finding regularities … You might find that certain sounds are more likely to change than others."
So Bouchard-Côté's team tested the "functional load hypothesis（假設(shè)）," which says that sounds that are more important for two clearly different words are less likely to change over time. A formal test of this hypothesis in 1967 looked at four languages; Bouchard-Côté's algorithm looked at 637.
"The revealed pattern would not be obvious if we had not been able to reconstruct large numbers of protolanguages," Bouchard-Côté and his coauthors write in the new study.
In addition to simply helping linguists understand how people spoke in the past, studying ancient languages can perhaps answer historical questions. For example, Bouchard-Côté says, "Say people are interested in finding out when Europe was settled. If you can figure out if the language of the settling population had a word for wheel, then you can get some idea of the order in which things occurred, because you would have some records that show you when the wheel was invented.”
小題1:The underline word “protolanguages” in the first paragraph probably refers to __________.
A．the languages that couldn’t be reconstructed by hand
B．parent languages that existed in the past
C．languages developed from a common ancestor
D．languages used to explain things that occurred in the past
小題2:We can learn from the fourth and fifth paragraphs that the reconstruction of “protolanguage” by scholars __________.
A．is commonly accepted as false
B．dates back to the 19th century
C．focuses on European languages
D．is conducted using the comparative method
小題3:According to Bouchard-Côté, reconstructing the dead "protolanguages" might     _______.
A．a(chǎn)rouse people’s interest in when Europe was settled
B．a(chǎn)llow us to find answers to some historical questions
C．enable us to picture the way linguists communicated
D．help figure out how the wheel was invented
小題4:The author probably wants to prove the computer algorithm program led by Bouchard-Côté ___________.
A．will bring every dead language back to life
B．can take the place of linguists in language analysis
C．is of great help to promote language analysis with big data sets
D．can merely reconstruct Asian-Pacific “protolanguages”

小題1:B
小題2:D
小題3:B
小題4:C

Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(輻射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
小題1:Which of the following statements is true?
A．Nuclear radiation is just like common radio waves.
B．Nuclear radiation can cause cancer to human beings.
C．Nuclear radiation can be detected by human senses.
D．Nuclear radiation can be safe to human beings if its level is low.
小題2:How can nuclear radiation kill an animal?
A．By damaging its heart.
B．By killing a few cells.
C．By hitting any place in its body.
D．By killing many cells in important organs.
小題3:If a human being is hit by nuclear radiation, he may __________.
A．die of cancer after many years
B．die immediately
C．have a child who may be born weak
D．a(chǎn)ll of the above

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmosphere CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. “We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmosphere CO2 into the ocean.”
Scientists expected that as atmosphere CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves in the water or seawater in this case, it forms a weak acid, carbonic acid,” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”
小題1:What can be the best title of the passage?
A．Scientist Researching Seawater
B．Sea Life Facing Danger
C．Oceans Becoming More Acidic
D．Climate Change Affecting Seawater
小題2:With the increase of atmospheric CO2, _______.
A．more corals will appear in the sea
B．the chemical balance of the seawater is affected
C．the surface water is becoming warmer
D．the pH of the ocean out here has been increasing
小題3:Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a. Sea life is endangered.
b. CO2 goes into the surface water.
c. The ocean chemistry is affected.
d. CO2 decreases the pH and makes the seawater more acidic.
e. CO2 levels in the atmosphere go up.
A．a(chǎn)→b→c→d→eB．e→b→c→d→a
C．a(chǎn)→e→b→c→dD．e→d→c→b→a
小題4:Scientist Robert Dore came to the conclusion based on_______.
A．the expectation of other scientists
B．some former theory
C．his research and analysis
D．a(chǎn) major cause of climate change

During her junior year of high school, Diane Ray's teacher handed her a worksheet and instructed the 17-year-old to map out her future financial life. Ray pretended to buy a car, rent an apartment, and apply for a credit card.  Then, she and her classmates played the "stock market game", investing（投資) the hypothetical（虛擬的） earnings from their hypothetical jobs in the market in the disastrous fall of 2008. "Our pretend investments crashed," Ray says, still frightened. "We got to know how it felt to lose money."
That pain of earning and losing money is a feeling that public schools increasingly want to teach. Forty states now offer some type of financial instruction at the high-school level, teaching students how to balance checkbooks and buy stock in math and social-studies classes. Though it's too early to measure the full influence of the Great Recession（大蕭條）, the interest in personal-finance classes has risen since 2007 when bank failures started to occur regularly. Now, many states including Missouri, Utah, and Tennessee require teenagers to take financial classes to graduate from high school. School districts such as Chicago are encouraging money-management classes for kids as young as primary school, and about 300 colleges or universities now offer online personal-finance classes for incoming students. "These classes really say, 'This is how you live independently,' " says Ted Beck, president of National Endowment for Financial Education.
Rather than teach investment methods or financial skills, these courses offer a back-to-the-basics approach to handling money: Don't spend what you don't have. Put part of your monthly salary into a savings account, and invest in the stock market for the long-term rather than short-term gains. For Ray, this means dividing her earnings from her part-time job at a fast-food restaurant into separate envelopes for paying bills, spending and saving.  "Money is so hard to make but so easy to spend," she says one weekday after school. "That is the big takeaway."
Teaching kids about the value of cash certainly is one of the programs' goals, but teachers also want students to think hard about their finances long term. It's easy for teenagers to get annoyed about gas prices because many of them drive cars. But the hard part is urging them to put off the instant satisfaction of buying a new T-shirt or an iPod. "Investing and retirement aren't things teenagers are thinking about. For them, the future is this weekend," says Gayle Whitefield, a business and marketing teacher at Uth’s Riverton High School.
That’s a big goal for these classes: preventing kids from making the same financial missteps their parents did when it comes to saving, spending, and debt. Though the personal savings rate has increased up to 4. 2 percent, that’s still a far distance from 1982, when Americans saved 11. 2 percent of their incomes. “It’s hard for schools to reach strict money-management skills when teenagers go home and watch their parents increase credit-card debt. It’s like telling your kids not to smoke and then lighting up a cigarette in front of them,” Beck says.
Even with these challenges, students such as Ray say learning about money in school is worthwhile. After Ray finished her financial class, she opened up a savings account at her local bank and started to think more about how she and her family would pay for college. “She just has a better understanding of money and how it affects the world,” says her mother, Darleen－and that’s sown to the details of how money is spent from daily expenses to various taxes. All of this talk of money can make Ray worry, she says, but luckily, she feels prepared to face it.
小題1:The “stock market game” mentioned in Paragraph 1 is meant to       .
A．introduce a new course to students
B．help students learn about investment
C．teach how to apply for a credit card
D．encourage students’ personal savings
小題2:How does the writer show us that schools’ interest in teaching financial classes has increased in paragraph 2_________?
A．By giving examples. B．By providing data.
C．By raising questions.D．By making comparisons.
小題3:According to the passage, taking money-management courses will        .
A．better students’ learning methods
B．prevent students going into debt
C．help students get accepted by colleges
D．make students become very wealthy
小題4:After completing the financial class, Diane Ray is likely to       .
A．pay off all her debts. B．handle her money better
C．find a job in a bank. D．manage the family income
小題5:The passage is mainly about      .
A．ways to teach students to earn money

There are some things humans can go without. We can lose a kidney (腎)or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.

One such fish is the stout longtom（尖嘴魚 ）. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical(熱帶) fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. Its teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin（胰島素） that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.
小題1:What does the underlined phrase “get by” mean?
A．Live.B．Fight.C．Hunt.D．Recover.
小題2:Ryan Day ran the chemical tests in order to find out how the longtom ______.
A．catches smaller fish in the water
B．can jump so high to escape its enemies
C．digests the smaller fish in its body
D．uses acid to break down the protein
小題3:What plays a key role in the longtom’s digestion process?
A．AcidB．Trypsin.C．The stomach.D．Protein in its body.
小題4:Ryan Day’s results show that ______.
A．the longtom often waste energy
B．the longtom can make acid easily
C．the longtom’s high-protein food helps its unique way of consuming food.
D．meat-eating fish have higher levels of trypsin in their bodies than plant-eating fish

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very probably be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
小題1: The writer is in favor of the view that man’s intelligence is given to him____________.
A．a(chǎn)t birth
B．through education
C．neither at birth nor through education
D．both at birth and through education
小題2:If a child is born with low intelligence, he can_____________________.
A．become a genius
B．still become a genius if he should be given special education
C．reach his intelligence limits in rich surroundings
D．not reach his intelligence in his life.
小題3:The example of the twins going to a university and to a factory separately shows_________.
A．the importance of their intelligence
B．the importance of their positions
C．the role of environment on intelligence
D．the part that birth plays
