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 technology—90 percent of those in the study had seen a 3D film．Schools would need 3D—enabled 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 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(小玩意儿)．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．

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．

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

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．

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

A．absorbed       B．annoyed

C．relaxed         D． confused

 

Answer 1

【答案】

 

1.B

2.D

3.D

4.A

【解析】

试题分析：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。

1.推理题：根据文章前三段内容可知3D用于教学中的有效性，可提高教学效果。故选B。

2.推理题：根据第四段中“While I think the idea of 3D technology is very interesting，

I worry that 3D is a bit of an expensive gimmick”虽然我认为3D技术的想法很有趣,但我担心3D有点昂贵的小玩意。由此可知有些学校负担不起3D技术带来的费用。故选D。

3.细节题：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.”在美国科罗拉多州的一个学区已经有1千台3D在教室中使用。故选D。

4.推理题：划线部分句意为那些观看3D演示的孩子更加全神贯注。“engrossed”意为“全神贯注于，专注于”，A．Absorbed全神贯注的；B．Annoyed生气的；C．Relaxed放松的；D． Confused困惑的。这四项中只有A项语意相近。故选A。
