分析 这是一篇科技报道.当你旅行归来,带这满满一包纪念品,如果有一个会走路的行李箱,那就太方便了.以色列的一家公司就开发了一款智能行李箱.它不但能认路,还可以防盗.预计每年就可以上市出售.这种行李箱对老年人或行动困难的人帮助很大.此外,该公司计划开发智能购物车.

解答 答案:61.enjoyable;考查形容词.句中enjoy修饰名词trip,要用形容词形式.    
62.a;考查冠词.句中high-tech company from Istael作Nua Robotics的同位语,要用不定冠词来限定.  
63.has developed;考查时态.句意表达的是已经完成的动作,要用现在完成时态.   
64.that/which;考查连词.句中will follow you everywhere like a pet dog修饰名词suitcase,是一个定语从句;从句缺少主语,且先行词suitcase指物,要用that或which来引导.   
65.weight;考查名词.句中weight表示重量,抽象名词,用原形即可.
66.being stolen;考查语态.句中steal与it之间构成动宾关系,要用被动;steal位于介词from后,要用动名词形式,故填being stolen.   
67.at;考查短语搭配.at a price of以…的价格.    
68.physically;考查副词.句中physical修饰形容词disabled,要用副词形式.    
69.it;考查句型搭配.find it+形容词+to do sth发现做某事怎么样;it充当形式宾语,真正的宾语是后面的动词不定式.            
70.to use;考查短语搭配.plan to do sth计划做某事.

点评 语法填空题是考查学生的语言运用能力.解题时,要在理解文章的基础上,灵活运用语法知识,如词性,时态,名词单复数,连接词,代词,冠词等判断空白处应填写的内容.答完后,还要通读全文,核对所填单词形式是否正确,是否符合语境.

9.If you saw another kid ride her bike too fast around a corner and fall down,you might ride your bike more slowly on that turn.Yes,we humans are very sensitive to others'mistakes.And the same is true for other animals.Animals mess up all the time.They might eat poisonous leaves,fall off a tree or let their prey(猎物) slip away.By watching others fail,an animal can avoid making the same mistakes,thus improving its chance of survival.
Scientists suspected that one part of the brain helps animals process information about others'errors.Cells in that part appear to become more active when a person sees someone else making a mistake.But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors.
To investigate the brain's response to errors in more detail,the researchers taught a game to two macaques,a type of monkey.One monkey could press a yellow or green button while the other watched.If the first monkey pressed the right button,the team gave both animals a treat.Every couple of rounds,the two monkeys switched roles.Meanwhile,the scientists monitored individual cells in the animal's brains.
When the first monkey messed up the game by pressing the wrong button,a group of cells in the second monkey's brain fired.But if the second monkey also made the wrong choice during its turn,some of the cells in that group didn't respond.Those unresponsive cells reacted specifically to mistakes made by others,not to the monkey's own mistakes.
Scientists believe other parts of the brain also might help people process information about another's errors."You start to think about this other person and see things from his angle."Ellen de Bruijn told Science News.She studies the brain at the University of Leiden in the Netherlands.

31.According to Paragraph l,animals'ability to learn from others'mistakes.B
A.used to be ignored by humans        
B.helps them to survive better
C.is being lost because of humans        
D.ensures that they will never fail
32.The underlined word"detecting"in Paragraph 2probably means"D".
A.correcting      
B.making      
C.drawing     
D.sensing
33.From the game the scientists taught to two macaques,we can see.C
A.animals can avoid the same mistakes    
B.which part of the brain is more active
C.how the brain responds to mistakes    
D.how the brain processes information
34.In the experiment mentioned,those unresponsive cells are only sensitive toA.
A.others'mistakes            
B.the same buttons
C.one's own mistakes                
D.the monkey's brain
35.What's the main idea of the passage?A
A.Animals can learn from mistakes like human beings.
B.An interesting experiment by scientists surprised us.
C.Monkeys can avoid making mistakes by learning from us.
D.The brain cells are always sensitive to others'information.
