Question

3．Robot scientists（70）are not just trying to make robots look like people．For example，there are already robots working（71）in factories．These robots look more like huge arms．They do simple jobs over and over again．People would not like to do such jobs and would get bored．But robots will never get bored．In the future，there will be more robots everywhere（72），and humans will have less（73）work to do．New robots will have many different shapes．Some will look like humans，and others might look like snakes．After an earthquake，a snake robot could help look for people under buildings（74）．That may not seem possible now，but computers，space rockets and even electric toothbrushes seemed impossible（75）a hundred years ago．We never know what will happene in the future．

Answer 1

分析 机器人科学家不只是试图让机器人看起来像人，还能做许多事情，机器人越多，人类干得活儿越少，蛇形机器人在建筑物下面帮助找人比较方便．

解答 70．scientists  考查名词的辨析．根据句意：机器人科学家不只是试图让机器人看起来像人，即 研究制造机器人的是科学家，根据动词are，确定用复数形式，故填scientists．
71．working．考查固定句型．根据题干可知是使用了"there be sb．doing…"句型，现在分词修饰做主语的名词robots，结合句意：已经有在工厂里工作的机器人，故填working．
72．everywhere考查副词的辨析．结合有：未来将会到处是机器人，此处表示地点，应该用everywhere．
73．less考查比较级的辨析．与前面的more相呼应，意思是机器人越多，人类干得活儿越少．故填less．
74．buildings考查名词的辨析．根据句意：地震后这种机器人在建筑物下面帮助找人比较方便．故填buildings，可数名词，注意应该用名词的复数．
75．impossible考查形容词的辨析．根据上句的"may not seem possible"或许看起来是可能的，可知此处应该是：但一百年前，电脑、太空火箭甚至电动牙刷似乎是不可能的．故填impossible．

点评 做这类题，不但要选择正确意义的词、词组及句型，还要根据具体语法和语境，选择适当的时态、语态及使用正确的词形．
