Most forms of steel (26)_____ become brittle (脆的) at temperatures below about -25°C unless they are mixed with other metals. Now, though, a novel type of steel has been developed that resists (27)_____ at much lower temperatures, while retaining its strength and toughness—without the need for expensive (28)_____. Steel’s fragility at low temperatures first became a major concern during the Second World War. After German U-boats torpedoed (用鱼雷攻击) numerous British ships, a 2700-strong fleet of cheap-and-cheerful “Liberty ships” was introduced to replace the lost vessels, providing a lifeline for the (29)_____ British. But the steel shells of hundreds of the ships (30)_____ in the icy north Atlantic, and 12 broke in half and sank. Brittleness remains a problem when building steel structures in cold conditions, such as oil rigs in the Arctic. So scientists have (31)_____ to find a solution by mixing it with expensive metals such as nickel. Yuuji Kimura and colleagues in Japan tried a more physical (32)_____. Rather than adding other metals, they developed a complex mechanical process involving repeated heating and very severe mechanical deformation, known as tempforming. The resulting steel appears to achieve a combination of strength and toughness that is (33)_____ to that of modern steels that are very rich in alloy content and, therefore, very expensive. Kimura’s team intends to use its tempformed steel to make ultra-high strength parts, such as bolts. They hope to reduce both the number of (34)_____ needed in a construction job and their weight—by replacing solid supports with (35)_____ tubes, for example. This could reduce the amount of steel needed to make everything from automobiles to buildings and bridges.

Children with attention problems in early childhood were 40% less likely to graduate from high school, says a new study from Duke University.The study included 386 kindergarteners from schools in the Fast Track Project, a multi-site clinical trial in the U.S. that in 1991 began tracking how children developed across their lives.With this study, researchers examined early academic attention and socio-emotional skills and how each contributed to academic success into young adulthood.They found that early attention skills were the most consistent predictor of academic success, and that likability by peers also had a modest effect on academic performance.By fifth grade, children with early attention difficulties had lower grades and reading achievement scores than their peers. As fifth-graders, children with early attention problems obtained average reading scores at least 3% lower than their contemporaries' and grades at least 8% lower than those of their peers. This was after controlling for IQ, socio-economic status and academic skills at school entry.Although these may not seem like large effects, the impact of early attention problems continued throughout the children's academic careers. Lower reading achievement scores and grades in fifth grade contributed to reduced grades in middle school and thereby contributed to a 40% lower high school graduation rate."The children we identified as having attention difficulties were not diagnosed with attention deficit hyperactivity disorder(注意力缺乏多动症)(ADHD), although some may have had the disorder. Our findings suggest that even more modest attention difficulties can increase the risk of negative academic outcomes", said David Rabiner, an associate dean of Duke's Trinity College of Arts & Sciences, whose research has focused on ADHD and interventions to improve academic performance in children with attention difficulties.Social acceptance by peers in early childhood also predicted grades in fifth grade. Children not as liked by their first-grade peers had slightly lower grades in fifth grade, while those with higher social acceptance had higher grades."This study shows the importance of so-called 'non-cognitive' or soft skills in contributing to children's positive peer relationships, which, in turn, contribute to their academic success, " said Kenneth Dodge, director of the Duke Center for Child and Family Policy.The results highlight the need to develop effective early interventions to help those with attention problems stay on track academically and for educators to encourage positive peer relationships, the researchers said."We're learning that student success requires a more comprehensive approach, one that incorporates not only academic skills but also social, self-regulatory and attention skills, " Dodge said. "If we neglect any of these areas, the child's development lags. If we attend to these areas, a child's success may reinforce itself with positive feedback loops."What is the focus of the new study from Duke University? A.The contributors to children's early attention.B.The factors that affect children's emotional well-being.C.The predictors of children's academic success.D.The determinants of children's development of social skills.What do we learn from the findings of the Duke study? A.Modest students are generally more attentive than their contemporaries.B.Children's academic performance may suffer from even slight inattention.C.Attention deficit hyperactivity disorder accounts for most academic failures.D.There are more children with attention difficulties than previously thought.What does the Duke study find about children better accepted by peers? A.They care less about grades.B.They are teachers' favorites.C.They are easy to get on with.D.They do better academically.What can we conclude from the Duke study? A.Children's success is related to their learning environment.B.School curriculum should cover a greater variety of subjects.C.Social skills are playing a key role in children's development.D.An all-round approach should be adopted in school education.

For many people, working out and alcohol are closely linked. Sports teams and training partners celebrate victories, bemoan defeats or mark the end of training sessions with a beer or three. Beer, in fact, provides a substantial portion of some exercisers' fluid intake after workouts. But whether exercise encourages people to drink and, likewise, whether drinking encourages people to exercise has been in dispute. Now new studies suggest that exercise may well influence when and how much people drink. Drinking may even affect whether people exercise, and, the findings suggest, the interplay between exercise and alcohol could be a good thing. Past studies have shown that people who exercise tend numerically also to be people who drink, and vice versa. But most of these previous studies had limitations. They relied, for instance, on people's ability to recall their exercise and drinking habits over the course of, say, the past year, which can be notoriously unreliable. They also rarely took into account participants' ages and gender, which affect how much people exercise and drink. What is the relationship between exercise and alcohol from the new studies? A. The interaction between exercise and alcohol are in dispute.B. Exercise may impact on how long and when people drink.C. The interaction between exercise and alcohol might be good.

"Other countries have a climate; in England we have weather." This statement is often made by Englishmen, which is both revealing and true. It is revealing because in it we see the Englishman insisting once again that what happens in England is not the same as what happens elsewhere; its truth can soon be found by any foreigner who stays in the country for longer than a few days. It has been said only in England can one experience four seasons in the course of a single day! Day may break as a balmy spring morning; an hour later black clouds may have appeared from nowhere and the rain may be pouring down. At midday conditions may be really wintry with the temperature down by about eight degrees or more. And then, in the late afternoon the sky will clear, the sun will begin to shine, and for an hour or two before darkness falls, it will be summer. In England one can experience almost every kind of weather except the most extreme. Some foreigners seem to be under the impression that for ten months of the year the country is covered by a dense blanket of fog; this is not true. The problem is that we never can be sure when the different sorts of weather will occur. Not only do we get several different sorts of weather in one day, but we may very well get a period of winter in summer and a period of summer in winter. This uncertainty about the weather has had a definite effect upon the Englishman's character; it tends to make him cautious, for example. The foreigner may laugh when he sees the Englishman setting out on a sunny morning wearing a raincoat and carrying an umbrella, but he may well regret his laughter later in the day! The English weather has also helped to make the Englishman adaptable. It has been said that one of the reasons why the English colonized (开拓殖民地) so much of the world was that, whatever the weather conditions they met abroad, they had already experienced something like them at home! And, of course, the weather's variety provides a constant topic of conversation. Even the most unfriendly of Englishmen is always prepared to discuss the weather. And, though he sometimes complains bitterly of it, he would not exchange it for the more predictable (可以预测的) climate of other lands.1.

By reading the last sentence, we can see that Englishmen's basic attitude towards their weather is ________.A) positive B) bitterC) helplessD) indifferent4. Which of the following words can't we use to describe the English weather?A) Varied.B) Uncertain.C) Changeable.D) Predictable. 5. Which of the following is not the writer's view?A) Weather is Englishmen's favorite topic of conversation.B) For most of the year it is foggy in England. C) The English weather has affected Englishmen's character.D) Englishmen could easily make themselves fit for the local weather wherever they went.

35If you’ve ever looked at the ingredients list while grocery shopping, chances are you’ve seen the term “natural flavors”. But have you taken a 26 to consider what these natural flavors actually are?Most of us might think that “natural flavors” are, well, naturally good for us. A recent study in the journal Appetite found that when the word “natural” appears on packaging, people 27 that the food within is indeed healthier. In truth, natural flavors do not 28 much, at least chemically speaking, from their flavor-boosting 29: artificial flavors. Both can be made in a lab by trained flavorists, but artificial flavors use chemicals to give a product a 30 smell or taste.Natural flavors come from plant or animal 31, like fruit, vegetable, meat, fish or milk that is then processed or refined in some way. In short, natural flavors are 32 from plants and animals to create specific flavors for processed foods. But that does not 33 make it easier to tell what is really in your food. Because the Food and Drug Administration (FDA) has not 34 the term, companies can use it to refer to pretty much anything derived from a plant or animal. And natural flavors can also include a variety of chemical additives, such as preservatives. The FDA doesn’t require companies to reveal what additional chemicals a specific item 35.So if you want to know for certain what you’re getting with your groceries, you might want to stick to the farmer’s market.A、acknowledgeB、chanceC、containsD、counterpartsE、definedF、differG、especiallyA.extractedB.impliesC.necessarilyD.particularE.perceiveF.secondG.sourcesH.strange
