Professor Anne Bamford,of the University of the Arts,London,studied the effectiveness of 3D content in 15 schools across seven countries,including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding,increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology90 percent of those in the study had seen a 3D film.Schools would need 3Denabled projectors(投影仪),laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use inschools and could be costly.He said,“While I think the idea of 3D technology is very interesting,I worry that 3D is a bit of an expensive gimmick(小玩意儿).There are a few cases where a true3D image might help,but most of the time,good 2D models that can be moved would be just aseffective.”
In the US,one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
小题1:What is the main idea of the first three paragraphs?
A.There are slight differences between 3D and 2D images. |
B.Pupils perform better when 3D images are used in classes. |
C.Schools have difficulties in making full use of 3D technology. |
D.3D technology is always more effective than 2D technology. |
A.is of no help in classes |
B.has a bright future in classes |
C.is more practical than 2D models |
D.may not be affordable for schools |
A.3D technology will replace 2D models in the future. |
B.Many pupils are now more Interested In science than before. |
C.Teachers will use the 3D technology through specific training. |
D.3D will soon be put into use in one school district in Colorado. |
A.absorbed | B.annoyed |
C.relaxed | D.confused |
答案
小题1:B
小题2:D
小题3:D
小题4:A
解析
文章大意:本文讲述了3D影响在教学中的应用,虽然有人提出反对意见,但研究表明了3D用于教学的有效性,提高了教学效果:提高了学生的记忆效果、理解能力和接受能力,而且在美国的科罗拉多州的一个学校已经投入使用。
小题1:B 主旨大意题。前三段的主题句是第一段第一句话,所以B项正确。
小题2:D 细节理解题。由倒数第二段的But可知,Danny Nicholson 持相反的观点;再根据Danny Nicholson 的话“While I think the idea of 3D technology is very interesting,I worry that 3D is a bit of an expensive gimmick(小玩意儿).”可知,Danny Nicholson认为,3D是不切实际的,因为很多学校负担不起。
小题3:D 推理判断题。根据最后一段第一句话“In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms”,得出在科罗拉多3D课堂会在一个学校开展,D项正确。
小题4:A 猜测词义题。由划线词后的“and reported a general increase in their interest in science”可推知,观看3D课堂的学生会更加注意力集中,而且会对科学越来越感兴趣。所以划线词应为“集中注意力的”。

Ma Xingrui, chief mander of China"s lunar programme, declared the mission (任务)a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China"s ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang"e3 mission landed some 12 days after being launched atop a Chinesedeveloped Long March 3B rocket from Xichang in the country"s south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13:00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球车) in Shanghai a few years ago it"s a wonderful technological achievement to have landed,” Prof Andrew Coates, from UCL"s Mullard Space Science Laboratory, told BBC News.
Chang"e3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod2, which was kept warm by polonium(钋)210. But the sixwheeled Chinese vehicle carries a more sophisticated payload(复杂的有效负荷), including groundpenetrating radar which will gather measurements of the lunar soil and crust.

Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牵牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants,” they added.

Asian carp are strong to jump over barriers such as low dams. They lay hundreds of thousands of eggs at a time and spread into new habitat quickly and easily. Also, flooding has helped the fish expand into previously unattainable water bodies. And fishers using young carp as live bait have also helped the fish"s spread, as they have boats going through locks up and down the Mississippi.
The federal government considers the Asian carps to be annoying species and encourages and supports “active control” by natural resources management agencies. Federal and state governments have spent millions in tax dollars to prevent the carp from making their way into the Great Lakes, but an underwater electric fence constructed to keep them out has not worked as well as hoped, and policymakers are reviewing other options now.
In the meantime, state and federal agencies are monitoring the Mississippi and its branches for Asian carp and testing various barrier technologies to prevent their further spread. For instance, the National Park Service is cooperating with the state of Minnesota"s Department of Natural Resources to construct new dams that are high enough to prevent Asian carp from jumping over. The Asian Carp Regional Coordinating Committee has funded DNA monitoring in potentially affected water bodies whereby researchers can determine whether the troublesome fish are present just by the biological footprints they leave behind. Individuals can do their part by not transporting fish, bait or even water from one water body to another, and by emptying and washing boats before moving them between different water bodies.

C.both the state and the individuals can make efforts to keep out Asian carp |
D.Asian carp have successfully invaded the Mississippi and the Great Lakes |
That American high schools spend more time and money on sports than on math is an old complaint. In December, when the latest Program for International Student Assessment (PISA) results are announced, it"s safe to predict that American highschool students will once again show their limited skills in math and reading, outscored not just by students in Poland but also by students in places like China, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader a mother with three children in the school was asked about the school"s flaws (瑕疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies of the situation is that sports show what is possible. American kids" performance on the field shows just how well they can do when expectations are high. It"s too bad that their_test_scores_show_the_same_thing._
小题1:Tom decides to spend his senior year in Poland because ________.
A.he intends to improve his scores |
B.Polish kids are better at learning |
C.sports are not supported at schools in Gettysburg |
D.he wants to be the smartest kid in the world |
A.PISA plays a very important role in America |
B.little time is spent on sports in Japanese schools |
C.American students do better in both math and sports |
D.too much importance is placed on sports in America |
A.low expectations result in American students" poor PISA performance |
B.high expectations push up American students" academic performance |
C.American students" academic performance worries their parents a lot |
D.lacking practice contributes to American students" average performance |
A.compare Polish schools with those in America |
B.call on American schools to learn from the Polish model |
C.draw public attention to a weakness in American school tradition |
D.explain what is wrong with American schools and provide solutions |
