Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; _________________, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way children, learning to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances(表現(xiàn))with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he became dependent on the teacher.
Why should we teachers waste time on such tiring work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let’s end all this nonsense(荒謬的)of grades, exams and marks. Let us throw them all out, and let the children learn what all educated persons must someday learn, how to measure their own understanding, how to know what they know or do not know.
We should, of course, offer help to them just as they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated(復(fù)雜的)and rapidly changing as ours. Don’t worry! If something is basic, they will go out into the world and learn it.

試題分析:讓孩子們自己評(píng)判他們的學(xué)習(xí),讓他們自己去發(fā)現(xiàn)錯(cuò)誤并自己改正錯(cuò)誤。作者為老師,應(yīng)該轉(zhuǎn)變以前那種給學(xué)生指出錯(cuò)誤并監(jiān)督他們改正的教學(xué)觀念,注重培養(yǎng)孩子獨(dú)立思考和判斷的能力。
小題1:根據(jù)第一段“Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time ...But in school we never give a child a chance to find out his mistakes for himself, let alone correct them.”可知,文章大意說的是,讓孩子學(xué)會(huì)自己評(píng)判他們的工作,老師要給孩子自學(xué)的機(jī)會(huì)。故填Let children judge their own work. /Let children learn by themselves. /Give children chances to learn by themselves.
小題2:根據(jù)第一段“We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to.”可知,老師認(rèn)為,如果不給孩子指出錯(cuò)誤,他就不會(huì)注意到那個(gè)錯(cuò)誤;如果不讓孩子去改正錯(cuò)誤,他就不會(huì)去改正。故填We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to.
小題3:根據(jù)“A child learning to talk does not learn by being corrected all the time”中的all the time可知,不應(yīng)該一直提醒孩子要糾正錯(cuò)誤,而應(yīng)該讓孩子自己發(fā)現(xiàn)并加以改正。故填I(lǐng)f (he is) corrected too much/frequently/too often。
小題4:根據(jù)第二段“Our job should be to help the child when he tells us that he can’t find the way to get the right answer.”和第三段“We should, of course, offer help to them just as they ask for it.”可知,老師應(yīng)該做的事情是,當(dāng)孩子找不到答案向老師求助時(shí),老師才伸出援助之手。故填(A teacher should) offer help when a child asks for it. A teacher should help the child when he can’t find the way to get the right answer.
小題5:根據(jù)“Let’s end all this nonsense(荒謬的)of grades, exams and marks. Let us throw them all out”中的nonsense可知,作者認(rèn)為分?jǐn)?shù)和考試是沒有意義的,故填(The author thinks) them (that they are) nonsense /useless/ meaningless/pointless/(that) they make no sense.

Electric cars are dirty.In fact,not only are they dirty,they might even be more dirty than their gasoline­powered cousins.
People in California love to talk about “zero­emissions vehicles”,but_people_in_California_seem_to_be_clueless_about_where_electricity_comes_from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells,we get our electricity from generators.Generators are fueled by something—usually coal,oil,but also by heat generated in nuclear power plants.There are a few wind farms and geothermal(地?zé)岬? plants as well,but by far we get electricity mainly by burning something.
In other words,those “zero­emissions” cars are likely coal­burning cars.It’s just because the coal is burned somewhere else that it looks clean.It is not.It’s as if the California Greens are covering their eyes—“If I can’t see it,it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle;a gallon of gas has a lot of energy in it.But when you take that gas(or another fuel) and first use it to make electricity,you waste a nice part of that energy,mostly in the form of wasted heat—at the generator,through the transmission(傳送) lines,etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won’t get you nearly as far—so electric cars burn more fuel than gas­powered ones.If our electricity came mostly from nukes;or geothermal,or hydro,or solar,or wind,then an electric car truly would be clean.But for political,technical,and economic reasons,we don’t use much of those energy sources.
In addition,electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill.And finally,when cars are the polluters,the pollution is spread across all the roads.When it’s a power plant,though,all the junk is in one place.Nature is very good at cleaning up when things are too concentrated,but it takes a lot longer when all the garbage is in one spot.
小題1:What does the underlined part mean in Paragraph 2?
A.People see the California Greens everywhere.
B.People in California love to talk about zero­emissions vehicles.
C.People in California love to have their roofs covered with solar cells.
D.People in California have no idea that so far electricity mainly comes from burning coal,oil,etc.

A.Electric cars are not clean at all.
B.Electric cars are better than gasoline­powered ones.
C.People cast doubts on electric cars’ batteries.

小題3:The electricity we get from a gallon of gas may make our car run ________.
A.not less than 25 miles
B.a(chǎn)s far as 50 miles
C.a(chǎn)s far as 25 miles
D.not more than 25 miles

The £109 Nest Protect Smoke Alarm promises Internet alerts(警報(bào))and an end to the low battery chirp(短而尖的叫聲). Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep(嘟嘟聲). And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”
小題1:For what purpose did Nest create the Protect Smoke Alarm?
A.To predict low-level fire risks.B.To experiment with a new battery.
C.To improve present smoke alarms.D.To avoid the low-battery chirp.
小題2:What did Tony Fadell really want to tell us in Paragraph 3?
A.One of his cooking experiences.
B.Disadvantages of present smoke alarms.
C.His growing distrust of smoke alarms.
D.His source of annoyance to crying wolf.
小題3:Which of the following are the advantages of the Protect Smoke Alarm?
a. Rechargeable batteries         b. A talking smoke alarm
c. Longer battery life            d. Going off constantly
e. Internet connection
A.a(chǎn), b, cB.c, d, eC.a(chǎn), c, eD.b, c, e
小題4:What can we know from the last paragraph?
A.In the UK people seldom set up smoke alarms.
B.Matt Rogers didn’t like the safety requirements.
C.Non-functioning smoke alarms make people annoyed.
D.The government should pay attention to safety issues.

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

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

In 1901, H.G.Wells, an English writer, wrote a book describing a trip to the moon.When the explorers landed on the moon, they discovered that the moon was full of underground cities.They expressed their surprise to the “moon people” they met.In turn, the “moon people” expressed their surprise.“Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H.G.Wells could only imagine travel to the moon.In 1969, human beings really did land on the moon.People today know that there are no underground cities on the moon.However, the question that the “moon people” asked is still an interesting one.A growing number of scientists are seriously thinking about it
Underground systems are already in place.Many cities have underground car parks.In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas.The “Chunnel”, a tunnel(隧道) connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities.” The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on.A solar dome(太陽(yáng)能穹頂) would cover the whole city.
Supporters of underground development say that building down rather than building up is a good way to use the earth’s space.The surface, they say, can be used for farms, parks, gardens, and wilderness.H.G.Wells’ “moon people” would agree.Would you?
小題1:The explorers in H.G.Wells’ story were surprised to find that the “moon people” _____.
A.lived in so many underground cities
B.knew so much about the earth
C.understood their language
D.were ahead of them in space technology
小題2:What does the underlined word “it” refer to?
A.Discovering the moon’s inner space.B.Traveling to outer space.
C.Meeting the “moon people” again.D.Using the earth’s inner space.
小題3:What sort of underground systems are already here with us?
A.Tunnels, car parks, shopping areas.
B.Offices, shopping areas, power stations.
C.Gardens, car parks, power stations.

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

“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多種維生素make you healthier?
“We believe that the case is closed - supplementing(補(bǔ)充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(認(rèn)知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰劑)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.
小題1:This text is likely to be selected from a book of           .
A.medicineB.educationC.foodD.business
小題2:Which of the following is NOT Dr. Edgar Miller’s opinion according to the passage?
A.Vitamins should not be used for chronic disease prevention. Enough is enough.
B.Having a balanced diet and exercising would probably be a better way to keep healthy.
C.The three studies do not provide support for use of multivitamin supplements.
D.Taking vitamins to replace or supplement your healthy diet is necessary.
小題3:What can be inferred from the text?
A.Vitamin supplements have proved harmful to the health of adults.
B.Vitamin supplements are beneficial in certain conditions.
C.Nowadays taking vitamin supplements is common to most people.
D.Daily multivitamins will make you healthier.

Everybody knows how to learn.  Learning is  a natural thing.  It begins the     we are  born.  Our first  teachers are our f amilies. At  home  we  learn  to talk and to         and feed ourselves. We learn these and other skills by       .
Then we go to school. A teacher tells us      to learn and how to learn.  Many teachers teach us, and we pass many tests and exams. Then people say we are      .
Are we really educated? Let's     the real meaning of learning.  Knowing facts doesn't          being  able to solve problems.  Solving  problems requires creativity, not just a good     . Some people who don’t know many       can also be good at solving problems.
Henr Ford is a good       . He left school at the age of 15. Later, when his company couldn’ t build cars     enough, he solved the problem. He       of the assembly line. Today the answer seems      . Yet, just think of the many university  graduates who       solve any problems.
