Unit 2 Cloning 一、閱讀理解。 Kanda really doesn’t like to walk alone.The scientist from a research institute of intelligent robots finds the experience so boring that he’d rather drive—even though he lives close to his lab and knows that walking is healthy.“I enjoy walking with someone，like with my wife，with my daughter，” Kanda said.“But they are not always available.” So Kanda，who specializes in humanlike bots，developed a robotic walking partner that could make small talk based on its surroundings，which，he hopes，might motivate people to get out and exercise more.The bot rests on a person’s shoulder like a boxy parrot.It weighs about a pound and a half and sits roughly 8.5 inches high，and is 3.5 inches wide and 10 inches long.A microphone，a speaker，and an internal camera allow it to municate.It’s even equipped with a smile. Kanda and his team collected video from five different locations，including a garden and a shopping mall，and created a dataset of small talk topics related to each location.Then they programmed the robot to associate visual cues with specific topics.A special speech software provided the robot with a voice.Near a group of parked cars，for example，it might say，“In a big parking lot， sometimes I forget where I parked.” They tested the robot on 15 volunteers，10 males and 5 females，who were paid and averaged about 26 years old.“Have you ever blown a puff of dandelion（蒲公英） seeds into the air？”The robot asked a participant，who smiled and responded，“Yes，I often did that when I was a child.” Although several participants noted the robot’s weight，Kanda was surprised that no one considered the experience strange or funny.“I guess people enjoy new technologies，” he said. Just like a human partner，Kanda’s bot isn’t perfect.It’s not able to go for walks in heavy rain and，while the robot can make expressions，it can’t really hold a conversation，about which Kanda is most worried.Despite its limits，Kanda was forted by the bot’s presence.“I felt a kind of sense of being with someone，” he said，“particularly when it spoke.” 【解題導(dǎo)語】　本文主要介紹了新研發(fā)的陪人散步的機(jī)器人。 1.Why does Kanda have the idea of developing a robotic walking partner？ A.Because he wants someone to acpany him while walking. B.Because he has never developed a robot like a parrot. C.Because his family are unwilling to walk with him. D.Because he is crazy about developing robots. A　解析：細(xì)節(jié)理解題。根據(jù)第一段的“‘I enjoy walking with someone，like with my wife，with my daughter，’Kanda said.‘But they are not always available.’”可知，Kanda發(fā)明陪人散步的機(jī)器人的原因是想找個(gè)人在他散步時(shí)陪他，故選A。 2.What characteristic does the robot have？ A.It can “speak” and “see”. B.It can walk like a human being. C.It can municate with people freely. D.It is much more humorous than a real person. A　解析：推理判斷題。根據(jù)第二段倒數(shù)第二句以及第三段的“Then they programmed...with a voice.”可推知，這種機(jī)器人可以說話還可以看，故選A。 3.What is necessary for the robot to function？ A.A small size.　　　 B．A boxy shape. C.A human partner. D．A speech software. D　解析：細(xì)節(jié)理解題。根據(jù)第二段倒數(shù)第二句和第三段的“Then they programmed...A special speech software provided the robot with a voice.”可知，這種機(jī)器人是要配備麥克風(fēng)、揚(yáng)聲器、內(nèi)置攝像頭以及特殊的語音軟件的，故選D。 4.What is Kanda most likely to do about his robot next？ A.To make it more convenient to carry. B.To improve its conversational skills. C.To enable it to walk in heavy rain. D.To better its sound system. B　解析：推理判斷題。根據(jù)最后一段第二句的“it can’t really hold a conversation，about which Kanda is most worried”并結(jié)合全文的內(nèi)容可推知，接下來Kanda將要改善的是機(jī)器人的交流技能，故選B。 二、單句語法填空 1．She was forced ________ (retire) early from teaching because of ill health. 答案：to retire　be forced to do ... “被迫做……”；retire “退休”。 2．Many local people ________(object) to the building of the new airport. 答案：objected　object to ... “反對……”。 3．It wont make much ________(differ) whether you go today or tomorrow. 答案：difference　由空前的much可知應(yīng)填名詞difference。make a/no/some/much difference 表示“有/沒有/有些/有很大影響/作用/關(guān)系”。 4．He owes his success more ________luck than ________ ability. 答案：to; to　owe ... to ... “把……歸功于……”。 5．Alcohol acts on the brain, so drivers are forbidden________ (drink) it when they drive a car. 答案：to drink　be forbidden to do ... “被禁止做某事”。 6．________(strike) by strong snowstorms, the area faced a severe water and electricity shortage. 答案：Struck　過去分詞短語在該句中作原因狀語。 7．The question ________will take his place is still not clear. 答案：who　who引導(dǎo)同位語從句，在從句中作主語，表示“……的人”，從句說明question的內(nèi)容。 8．The advantage is ________the cost of this method is low. 答案：that　設(shè)空處引導(dǎo)表語從句在從句中不作成分，無語義，只起連接作用，故填that。 9．I cant ________(undertake) that you will win in the election. 答案：undertake　由空前的情態(tài)動詞can可知應(yīng)填動詞原形。I cant undertake that ... “我無法承諾……”。 10．You can use my puter on condition ________ you return it tomorrow. 答案：that　on condition that ... “條件是……；只要……”。 三、完形填空。 閱讀下面短文，從短文后各題所給的A、B、C和D四個(gè)選項(xiàng)中，選出可以填入空白處的最佳選項(xiàng)。 One Saturday afternoon，my mother was driving home.On the halfway，after __1__ her credit card to buy something at the store near the gas station，she put her wallet on the top of her car just for a moment to __2__ my phone call.And then __3__，she forgot and drove off.When arriving home，she realized that and thought that the __4__ of getting it again was small.
