10、e with human-like abilityC.once we make a machine as ple as the human brain, it will posses intelligenceD.robots will have control of the vast, man-made world in space1.C 事實(shí)細(xì)節(jié)題。第1段末提到，使機(jī)器具有智能的方法有兩種，要么安裝適宜軟件，要么改變其架構(gòu)，故C正確。2.A 觀點(diǎn)態(tài)度題。作者在最后一段提到智能機(jī)器人可為人類做很多好事，故他對(duì)機(jī)器人態(tài)度是肯定的，故A正確，同時(shí)排除C。文中只是說(shuō)機(jī)器人會(huì)超越人類,但并未提到會(huì)控制

11、人類，故B排除;D與第1段末的that toowill hen矛盾，故錯(cuò)誤。3.D 詞義理解題。文中提到硅將會(huì)終結(jié)碳的長(zhǎng)期統(tǒng)治地位，聯(lián)絡(luò)上文可知，硅指的是智能機(jī)器人，再結(jié)合上文的機(jī)器人會(huì)超越人類，故可確定碳指代的是人類。4.A 事實(shí)細(xì)節(jié)題。第3段首提到，智能機(jī)器人能幫助開(kāi)發(fā)遙遠(yuǎn)地區(qū)的條件是intelligence.increase tomatch thatof humans和cost declines,A與此相對(duì)應(yīng),故正確。5.B 推理判斷題。綜觀全文，作者討論制作智能機(jī)器人的可能性及其影響，B所述與此相符。文中指出智能機(jī)器人的自我繁殖就是設(shè)計(jì)自己，故A錯(cuò)誤;第1段指出在制作出與人腦一樣復(fù)雜的

12、機(jī)器人后，還必須花很長(zhǎng)時(shí)間安裝軟件或改變架構(gòu)后才能使其擁有智能，故C錯(cuò)誤;D中的控制人造世界屬過(guò)度推斷，文中并未提及。The human brain contains 10 thousand million cells and each of these may have a thousandconnections.Suchenormous numbers used to discourage us and cause us to dismiss thepossibility of making a machine with human -like ability, but now that
