Question

Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb 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 technology­90 percent of those in the study had seen a 3D film.Schools would need 3D­enabled 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 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(小玩意兒)．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.

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．a(chǎn)bsorbed B．a(chǎn)nnoyed

C．relaxed D. confused

 

Answer 1

1.B

2.D

3.D

4.A

【解析】

文章大意：本文講述了3D影響在教學中的應(yīng)用，雖然有人提出反對意見，但研究表明了3D用于教學的有效性，提高了教學效果：提高了學生的記憶效果、理解能力和接受能力，而且在美國的科羅拉多州的一個學校已經(jīng)投入使用。

1.B　主旨大意題。前三段的主題句是第一段第一句話，所以B項正確。

2.2】D　細節(jié)理解題。由倒數(shù)第二段的But可知，Danny Nicholson 持相反的觀點；再根據(jù)Danny Nicholson 的話“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)．”可知，Danny Nicholson認為，3D是不切實際的，因為很多學校負擔不起。

3.3】D　推理判斷題。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”，得出在科羅拉多3D課堂會在一個學校開展，D項正確。

4.4】A　猜測詞義題。由劃線詞后的“and reported a general increase in their interest in science”可推知，觀看3D課堂的學生會更加注意力集中，而且會對科學越來越感興趣。所以劃線詞應(yīng)為“集中注意力的”。
