2.Mind control
Imagine looking at something and being able to move it just by using your brain!That is exactly what the new technology called BrainGate can do---with the help of a robotic arm,anyway.
BrainGate is the idea of Professor John Donoghue and his team of researchers at the Brown Institute for Brain Science,USA.BrainGate is attached directly to the brain.First of all,gold wires are put into the part of the brain that controls movement.These are then connected to a small computer chip(芯片).When the person thinks about different movements,this creates electrical signals,which are picked up by the chip.After this,the signals that are created by the brain are sent back to a computer,which changes the signals into movements.Finally,the computer uses the robotic arm to carry out these movements.BrainGate can already be used to write an e-mail or play computer games,just by brain power.
The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost thousands of dollars per person.There are still many challenges ahead for Donoghue and his team.They are currently planning a mini wireless version,which will allow people to be connected to the
computer at all times.Donoghue also dreams of using this technology to help disabled people who can't move their arms or legs.He plans to connect BrainGate directly to their own paralysed limbs(瘫痪的胳膊或腿).This will mean that the person can control their own body again,without relying on a robotic arm.
This research is attracting the military's(军方的)attention as well.However,
It is easy to understand why scientists might be concerned about how thought-controlled machines could be used by the military.

32.What does the underlined word"These"in Paragraph 2 refer to?A
A.Wires.
B.Brains.
C.Thoughts.
D.Movements.
33.According to the text,what is one of BrainGate's disadvantages?A
A It is too expensive.
B.It needs improvement.
C.It is difficult to control.
D.It produces few movements.
34.How will Donoghue help disabled people?C
A.By making BrainGate smaller.
B.By developing a wireless version.
C.By attaching BrainGate to their bad limbs.
D.By replacing their limbs with robotic ones.
35.What does the military think of thought-controlled machines?A
A.They could be useful.
B.They could lead to disasters.
C.They would be in mass production.
D.They would face fierce competition.

13.There was a gardener who looked after his garden with great care.To water his flowers,he used two buckets.One was a shiny and new bucket.The other was a very old and worn-out one,(61)which had seen many years of service,but was now past its best.
Every morning,the gardener would fill up the two buckets.Then he would carry them along the path,one on (62)eachside,to the flowerbeds.The new bucket was very proud of itself.It could carry a full bucket of water (63)withouta single drop spilled.The old bucket felt very (64)ashamed(shame) because of its holes:before it reached the flowerbeds,much water (65)had escaped(escape) from the holes.
Sometimes the new bucket would say,"See how capable I am!How good it is that the gardener has me to water the flowers every day!I don't know (66)why he still bothers with you.What a waste of space you are!"
And all that the old bucket could say was,"I know I'm not very useful,but I can only do my best.I'm happy that the gardener still finds a little bit of use in me,at least."
One day,the gardener heard that kind of conversation.After (67)watering(water) the flowers as usual,he said,"You both have done your work very well.Now I am going to carry you back.I want you to look (68)carefully(careful) along the path."
Then the two buckets did so.All along the path,they noticed,on the side where the new bucket (69)was carried(carry),there was just bare earth; on the other side where the old bucket passed,there was a (70)joyous(joy) row of wild flowers,leading all the way to the garden.
17.Why do we laugh and get amusement from so many different things,from puns (双关语) to pratfalls?Why are some things funny to some people and not to others?How is that while a successful joke can cause pleasure,a sick one can cause serious harm?
Over the centuries,various scholars have attempted to produce a universally agreed-upon theory of humor.Plato and Aristotle introduced the superiority theory,the idea that people laugh at the misfortune of others.Their theory seems to explain teasing,but it doesn't work well for knock-knock jokes.Sigmund Freud argued for his relief theory,the concept that humor is a way for people to release psychological tension and reveal their inner fears and desires.Histheory works well for dirty jokes,less well for most puns.
The majority of humor experts today agree with the incongruity theory,the idea that humor arises when there's a gap between what people expect to happen and what actually happens.Incongruity has a lot going for it-jokes with unexpected funny lines,for example,fit well.But scientists have found that in comedy,unexpectedness is overvalued.
With the goal of developing a new,more satisfactory explanation,I produced"the gentle violation theory",the idea that humor arises when something seems wrong or threatening,but is actually OK or safe.A dirty joke,for example,trades on moral or social violations,but it's only going to get a laugh if the person listening is open enough to consider the subject OK to talk about.Similarly,puns can be seen as linguistic violations that still make grammatical sense.
And while most humor theories have struggled to account for tickling (挠痒痒),or just avoided the phenomenon altogether,my theory accounts for even this kind of laughter.Tickling involves violating someone's physical space in a gentle way.People can't tickle themselves-because it isn't a violation.

24.What is the author's attitude towards Plato and Aristotle's theory?A
A.Critical.
B.Approving
C.uncaring
D.Unclear
25.According to Sigmund Freud's theory,we can infer thatB.
A.people will laugh when they see others suffer
B.telling dirty jokes is a relief of one's nervous feelings
C.unexpectedness can explain how humor works
D.tickling doesn't involve psychological tension
26.According to the author,why are some things funny to some people but not to others?D
A.Because the sense of humor varies greatly from person to person.
B.Because people have different expectations for the same thing.
C.Because some people lack the sense of safety deep in their heart.
D.Because people's understanding of violation is different.
27.What is the author's main purpose of writing this passage?C
A.To draw people's attention to the research of humor.
B.To criticize people's misconceptions about humor.
C.To explain what exactly causes people to laugh.
D.To prove the sense of humor can be developed.
8.There's always that one student who never speaks.They constantly stare down at the desk or their work,afraid to direct their eyes else.Occasionally,they'll glance your way but only to look back down again.It is clear from their body language that the student is uncomfortable,but there's no way in making him feel at home.The timidity (胆小,羞怯) and the vulnerability(脆弱) in his eyes say all that needs to be said.
Though this student is an extreme example of an introvert(内向的人),there are still students like the student mentioned above.I know that one of this kind hide in the shadows of each of the world's classrooms.
In some countries,this little boy may swift through life successful,wealthy,and content with his life.However,the introvert cannot find comfort in America where there are outgoing,socially confident people,talking,shouting,and laughing for the world to hear.
America is a nation of those who peak freely.In fact,one of the most prized clauses of our Constitution is the freedom of speech.There is nothing we love more than the right to speak as we please,so much so that the burning of the American flag is a protected speech.Though it is looked down upon,the person who burnt the flag will not deserve a punishment of any kind.It's legal.
What seems to not be legal,however,is shyness.In a nation full of discussion,those who fear of speaking will not get by.In my high school,for example,teachers often hold Socratic Seminars of class discussion where students are expected to voice their opinions.Stressing the fact that what is said does not have to be correct,teachers encourage students to speak up.Most of the grades in my classes,in fact,rely heavily on participation.
Personally,I dislike public speaking.Class discussion where students mention repeated points over and over again is not my strength,but I must force myself to raise my voice.If I don't,often times there are other people talking for me.
Gradually I realized something else.Speaking stimulates the mind,enhances one's thoughts,and establishes a sense of confidence that wouldn't otherwise have been instigated.It may be uncomfortable and it may be embarrassing,but it's all worthwhile in the end.
Although I stress the importance of social confidence,it is not unheard of to see introverts stand out in various activities.In college,for example,they would be studying rather than spending the day with friends.They would be seen in a library rather than at a social event.Although these types of students lack the outgoing personality,they do not always lack the motivation and desire to succeed.Often times,the introverts will gather to form a friend group.Their happiness is from what brings them pleasure,and if they are content without speaking their mind,so be it.

61.We can learn from the passage is thatA.
A.it is not uncommon that in each of the world's classrooms there is an introvert
B.introverts swift through life successful and stand out in various activities in any country 
C.the writer's grades are not high because he dislikes public speaking  
D.from the writer's point,only when the introverts speak their mind can they succeed and gain happiness
62.What attitude does the writer hold towards introverts?A
A.Positive   
B.Negative  
C.Neutral     
D.Not Clear
63.which of the following words can replace the underlined word----instigated in paragraph 7?B
A.brought about   
B.inspired   
C.withdrawn
D.escaped
64.Which would be the best title for the passage?C
A.Introverts hidden in the shadows
B.Success of introverts
C.Speak for the speechless
D.Spe ak out,the speechless.
