The National Gallery of Art in Washington, D.C., is one of the world’s greatest art museums. Millions of people have entered its doors to see paintings by the world’s fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery’s 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem.
In past times, the owners of paintings did not protect them from damaging changes in humidity（湿度）and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over.
Light is another enemy of paintings. Ultraviolet rays（紫外线）in light cause paintings to fade（褪色）. Long ago, paintings often hung in dark churches and palaces. A coat of varnish（清漆）was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age.
To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new precautions, many of the world’s greatest paintings are being well protected for future generations to enjoy.

试题【The National Gallery of Art in Washington, D.C., is one of the world’s greatest 】；主要考察你对题材分类等知识点的理解。[详细]
举一反三
What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck.
If you arrange the 26 English letters alphabetically(按字母表的顺序)and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11="98," meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5="96," while love :12+15+22+5="54," and luck : 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money or prayer(祈祷)? They can’t , either.
Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude(态度).Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark.
Different attitudes lead to different courses of life. Most times people hope for a better life. It is possible that one will have a change for the better after one has changed one’s attitude.
When you change your manner and became friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive(积极地)attitude towards failure(失败),you’ll find it’s also rewarding though it has caused you losses.
小题1:In the writer’s opinion , what is the most important things in a person’s life?
| A．Hard-work. | B．Knowledge. | C．Money. | D．Attitude. |
| A．ask for help from others | B．say your prayers to God |
| C．change your attitude | D．try maths-solving methods |
| A．diffrent attitudes come from different courses of life. |
| B．mathematics can solve every problem easily in our daily life |
| C．failure sometimes can bring you good if you take a positive attitude |
| D．none of the English words except “attitude” equals to 100 or more |
Franz Kafka wrote that “a book must be the ax (斧子) for the frozen sea inside us. ”I once shared this sentence with a class of seventh graders, and it didn’t seem to require any explanation.
We’d just finished John Steinbeck’s novel Of Mice and Men. When we read the end together out loud in class, my toughest boy, a star basketball player, wept a little, and so did I. “Are you crying?” one girl asked, as she got out of her chair to take a closer look. “I am,” I told her, “and the funny thing is I’ve read it many times.”
But they understood. When George shoots Lennie, the tragedy is that we realize it was always going to happen. In my 14 years of teaching in a New York City public middle school, I’ve taught kids with imprisoned parents, abusive parents, irresponsible parents; kids who are parents themselves; kids who are homeless; kids who grew up in violent neighborhoods. They understand, more than I ever will, the novel’s terrible logic—the giving way of dreams to fate (命运).
For the last seven years, I have worked as a reading enrichment teacher, reading classic works of literature with small groups of students from grades six to eight. I originally proposed this idea to my headmaster after learning that a former excellent student of mine had transferred out of a selective high school—one that often attracts the literary-minded children of Manhattan’s upper classes—into a less competitive setting. The daughter of immigrants, with a father in prison, she perhaps felt uncomfortable with her new classmates. I thought additional “cultural capital” could help students like her develop better in high school, where they would unavoidably meet, perhaps for the first time, students who came from homes lined with bookshelves, whose parents had earned Ph. D.’s.
Along with Of Mice and Men, my groups read: Sounder, The Red Pony, Lord of the Flies, Romeo and Juliet and Macbeth. The students didn’t always read from the expected point of view. About The Red Pony, one student said, “it’s about being a man, it’s about manliness. ”I had never before seen the parallels between Scarface and Macbeth, nor had I heard Lady Macbeth’s soliloquies (独白) read as raps (说唱), but both made sense; the interpretations were playful, but serious. Once introduced to Steinbeck’s writing, one boy went on to read The Grapes of Wrath and told me repeatedly how amazing it was that “all these people hate each other, and they’re all white.” His historical view was broadening, his sense of his own country deepening. Year after year, former students visited and told me how prepared they had felt in their first year in college as a result of the classes.
Year after year, however, we are increasing the number of practice tests. We are trying to teach students to read increasingly complex texts, not for emotional punch (碰撞) but for text complexity. Yet, we cannot enrich (充实) the minds of our students by testing them on texts that ignore their hearts. We are teaching them that words do not amaze but confuse. We may succeed in raising test scores, but we will fail to teach them that reading can be transformative and that it belongs to them.

Plants are flowering faster than scientists predicted（预测）in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide（CO2）in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researches of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated（低估）the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments under-predicted the speed of the advance — for both leafing and flowering — that results from temperature increases,” the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis（光合作用）to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8℃ since 1900, and nearly 0.2℃ every ten years since 1979.
So far, efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century — a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.
小题1:What is the key information the author wants to give in Paragraph 1?
| A．Plants’ reaction to weather could have damaging effects on ecosystem. |
| B．The increasing speed of flowering is beyond scientists’ expectation. |
| C．Climate change leads to the change of food production patterns. |
| D．Food chains have been seriously damaged because of weather. |
| A．plants’ flowering is 8.5 times faster than leafing |
| B．there are 1,634 plant species on the four continents |
| C．scientists should improve the design of the experiments |
| D．the experiments failed to predict how plants react to climate change |
| A．they can prove the climate change clearly |
| B．they are very important in the food chains |
| C．they play a leading role in reducing global warming |
| D．they are growing and flowering much faster than before |
| A．It has risen nearly 0.2℃ since 1979. |
| B．Its change will lead to weather extremes. |
| C．It is 0.8℃ higher in 1979 than that of 1990. |
| D．It needs to be controlled within 2℃ in this century. |
If you are looking for an animal to take the title of “most violent fish in the sea”, then the tiger puffer (河豚) fish would have to be a strong contestant. Not only is it deadly poisonous --- though that doesn’t stop people trying to eat it --- but it is also able to scare off enemies by inflating itself to become much larger than normal, when it is young it even chews on its own brothers and sisters.
Tiger puffer fish attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. Then the larvae (幼鱼) move to the entries of rivers and lakes once they have grown a little. Then, having put on a lot of weight, they head out to sea. There’s no innocent childhood for the puffer fish, as Shin Oikawa of Kyushu University in Japan and his colleagues found out when they put the larvae of tiger puffer fish in the lab and monitored them for two months. They found that the larvae went through three steps in which their metabolic(新陈代谢) rates increased dramatically when they reached body weights of 0.002g, 0.01g, and 0.1g. When a larva went through one of these steps, its behavior also changed. For instance, once a larva had passed the first level it would have grown its first tooth and could start attacking larvae that had not yet reached that stage. Similarly, any larva that had reached the 0.01g or 0.1g levels would start attacking lighter larvae.
The researchers noted that the baby fish had a “relatively small mouth”, so rather than swallowing their brothers and sisters whole, they would bite pieces out of them. Despite this limitation, the fish caused plenty of deaths --- up to 12 per cent of the deaths that happened in the lab each day.
Those fish that grew fast enough to be able to chew on their fellows had an advantage. The extra food accelerated their growth and development. Tiger puffer fish are likely to be faster and swifter, so they can deal better with enemies.
As the name suggests, puffer fish can inflate to make themselves seem much larger than they really are, thus scaring off enemies. They do this by filling their stomachs, which are extremely elastic(弹性的), with water. If that’s not enough of a threat, the tiger puffer fish --- like most of the other puffer fish in the family --- carries a deadly toxin(毒素). Eat one puffer fish and the poison will paralyze (瘫痪) your muscles, including the muscles responsible for breathing, so death is usually caused by a lack of oxygen. Famously, the fish is a delicacy in Japan, where highly qualified chefs produce dishes that contain the safe level of the poison. Interestingly, the puffer fish does not go to the trouble of producing the poison itself. Instead, it hosts bacteria (细菌) that produce the stuff. It obtains these bacteria from its diet, so the youngest adult fish are not poisonous.
小题1:All of the following statements account for the violence of puffer fish except that_____.
| A．they are very difficult to catch |
| B．they can become larger to threaten enemies away |
| C．they kill their younger companions as they grow up |
| D．they are deadly poisonous |
| A．can only grow to a weight of 0.1g |
| B．do not change their behavior as they grow up |
| C．like to find a safe place to hatch the next generation |
| D．begin to grow teeth when they reach the third level |
| A．Its inner organs. | B．The air it breathes in. |
| C．The diet it eats. | D．The bacteria around it. |
| A．Puffer fish can only produce poison when they face danger. |
| B．People like eating puffer fish even though they are poisonous. |
| C．The larvae are more aggressive than adult puffer fish. |
| D．Young puffer fish taste better than adult puffer fish. |
For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).
Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安装) a large number of internet-connected features in machines in an effort to make them “smart”.
Last year, it was a refrigerator that tweeted. This year, it’s Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.
The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners is at work or on the bus.
Samsung says it’s not just something new — the app connection actually has some practical uses.
“If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.
The company also says that with electricity rate(电价)varying depending on the time of day, more control over when the machines are used can help save money.
Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.
小题1:What can be inferred from the common response of the attendees at the CES?
| A．The machine will be a big success. |
| B．their wives like doing the laundry. |
| C．The machine is unrelated to their life. |
| D．This kind of technology is familiar to them. |
| A．They can tell you when your clothes need washing |
| B．They can be controlled with a smartphone |
| C．They are difficult to operate |
| D．They are sold at a low price |
| A．the app connection makes life easier |
| B．it is better to dry clothes in the morning |
| C．smartphone can shorten the drying time |
| D．we should refresh clothes back at home |
| A．The laundry should be frequently checked |
| B．Lazy people like using such machines |
| C．Good technologies also cause problems |
| D．Television may help do the laundry. |
