分析 本文主要講述很多青少年喜歡玩被叫做"太空武士"、"黑暗入侵者"等的電子游戲,過多地玩則會(huì)產(chǎn)生"太空武士腕",還可能影響肘部和肩部.甚至英國醫(yī)學(xué)雜志報(bào)道了一個(gè)17歲少女因玩完一個(gè)名叫"黑暗入侵者"的游戲后,她失去了知覺摔倒在地.因此,作者是不同意青少年玩這種游戲的.
解答 28--31 DACB
28.D 細(xì)節(jié)理解題.根據(jù)第一段In most towns today,you can see teenagers standing over electronic machines with flashing lights,shooting at spaceships from other planets and dropping bombs on strange monsters可知,現(xiàn)在在大多數(shù)城鎮(zhèn),你都能夠看到很多青少年站在不斷閃爍的電子游戲機(jī)前面,對(duì)著來自外行星的飛船射擊、對(duì)著奇異的怪物投擲炸彈,即這些電子游戲受到青少年的歡迎.故選D.
29.A 細(xì)節(jié)理解題.根據(jù)第二段They spend hours tightly holding the joystick controls and constantly pressing buttons marked"fire".They develop pains on their fingers because of the constant pressure(他們連續(xù)數(shù)小時(shí)抓住游戲機(jī)控制桿,不斷按著"開火"鍵.因?yàn)椴粩嗍┝Γ麄兊氖种钢饾u變得疼痛起來)和The muscles of the wrist and arm become so inflamed and swollen(充血紅腫) that they press against the bones.This condition is what doctors now call"Space Warrior's Wrist".(腕部和胳膊的肌肉變得腫脹,并壓迫到骨頭.這就是醫(yī)生們所說的"太空武士腕")可知,"太空武士腕"是由連續(xù)按按鈕產(chǎn)生的.故選A.
30.C 推理判斷題.根據(jù)第四段Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal可知,近來,英國醫(yī)學(xué)雜志報(bào)道了一個(gè)17歲少女的案例.這一案例揭示了一個(gè)更加令人吃驚的問題,由此看來,作者是不認(rèn)可青少年玩這種游戲的.故選C.
31.B 推理判斷題.根據(jù)第二段Many teenagers like electronic games so much that they can't stop playing.They spend hours tightly holding the joystick controls and constantly pressing buttons marked"fire"(很多青少年對(duì)于電子游戲愛不釋手.他們連續(xù)數(shù)小時(shí)抓住游戲機(jī)控制桿,不斷按著"開火"鍵.)和This condition is what doctors now call"Space Warrior's Wrist".Other strange aches and pains also are likely to affect the elbows and shoulders(這就是醫(yī)生們所說的"太空武士腕".其他各種怪異的疼痛也同樣可能影響肘部和肩部)可知,這種游戲既興奮,又對(duì)健康不利.故選B.
點(diǎn)評(píng) 高考中選用的科技文往往反映的是當(dāng)今人類最先進(jìn)的科技水平和最新的科研成果.我們閱讀它的過程其實(shí)就是學(xué)習(xí)科學(xué)知識(shí),掌握科技信息的過程.然后,理解文章,分析文章,以閱讀材料所提供的科學(xué)事實(shí)為依據(jù),同時(shí)得出的結(jié)論還應(yīng)符合基本的科普常識(shí),在細(xì)心對(duì)照基礎(chǔ)上,經(jīng)過一番分析、綜合,然后就要根據(jù)題目要求對(duì)選項(xiàng)作出正確判斷了,這些判斷包括選項(xiàng)的表達(dá)是否符合原文的意思,對(duì)概念,文句的理解是否正確,對(duì)要點(diǎn)歸納是否全面等,從而排除錯(cuò)誤選項(xiàng),選擇最合適的答案.
