Question

Pupils remember more and behave better when 3D images are used in lessons，research suggests．They are quicker to learn and absorb new concepts，and display higher levels of concentration．
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(模仿動作) 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 technology—90 percent of those in the study had seen a 3D film．Schools would need 3D—enabled projectors(投影儀)，laptops with good picture capabilities，3D software and glasses for children to introduce animations(動作) into classrooms．
But Danny Nicholson，an educationist，said the technology would be impractical to use in schools 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(小玩意兒)．There are a few cases where a true 3D image might help，but most of the time，good 2D models that can be moved would be just as effective．”
In the US，one school district in Colorado is already in the process of having 1．000 3D projectors 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．
小題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．

小題2:Danny Nicholson holds the view that 3D_____.

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

小題3:What can we learn from the last paragraph?

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．

小題4:The underlined word “engrossed” in the last paragraph means_____.

A．a(chǎn)bsorbed	B．a(chǎn)nnoyed
C．relaxed	D．confused

Answer 1

小題1:B
小題2:D
小題3:D
小題4:A

試題分析：本文講述了3D影響在教學(xué)中的應(yīng)用，雖然有人提出反對意見，但研究表明了3D用于教學(xué)的有效性，提高了教學(xué)效果：提高了學(xué)生的記憶效果、理解能力和接受能力，而且在美國的科羅拉多州的一個學(xué)校已經(jīng)投入使用。
小題1:推理題：根據(jù)文章前三段內(nèi)容可知3D用于教學(xué)中的有效性，可提高教學(xué)效果。故選B。
小題2:推理題：根據(jù)第四段中“While I think the idea of 3D technology is very interesting，
I worry that 3D is a bit of an expensive gimmick”雖然我認(rèn)為3D技術(shù)的想法很有趣,但我擔(dān)心3D有點(diǎn)昂貴的小玩意。由此可知有些學(xué)校負(fù)擔(dān)不起3D技術(shù)帶來的費(fèi)用。故選D。
小題3:細(xì)節(jié)題：根據(jù)最后一段第一句話“In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms.”在美國科羅拉多州的一個學(xué)區(qū)已經(jīng)有1千臺3D在教室中使用。故選D。
小題4:推理題：劃線部分句意為那些觀看3D演示的孩子更加全神貫注。“engrossed”意為“全神貫注于，專注于”，A．Absorbed全神貫注的；B．Annoyed生氣的；C．Relaxed放松的；D． Confused困惑的。這四項(xiàng)中只有A項(xiàng)語意相近。故選A。
