15．Pulling luggage through the airport can be a pain，as any frequent traveler will tell you．A new suitcase called only"Hop"is looking to change all of that，though，using signals from your cell phone to go hands-free．
According to Hop's official website，the suitcase uses three sensors （感應(yīng)器） to identify the Bluetooth signal from your phone and pick you out of a crowd．Once it's done that，a microprocessor not only figures out Hop's position as it relates to your phone，but controls the two caterpillar tracks （履帶） in the bottom of the unit to get it moving．Hop follows behind the user at a constant distance，so you don't have to worry about it"stepping"on your heels，so to speak．If it loses the signal it's following，your phone will vibrate，letting you know that your poor suitcase is lost and alone in a sea of strange people．
We can see Hop in action in the video below，and we have to say that it looks like a great little device．There's just one problem：it looks as if you'll have to walk at a relatively slow pace to keep the suitcase from losing the signal．Since a walk through an airport is rarely a leisurely experience，that could potentially cause troubles．Also，don't expect TSA agents to just smile and wave as you walk through security with a remote-controlled suitcase tailing you．
Still，the idea behind Hop is really cool，and we're willing to believe that there are some frequent flyers who would like to put down some money for it right this instant．However，this is just a model at the moment，so don't expect it to be available for sale anytime soon （if it ever is，for that matter）．Would you purchase one of these if Hop ever became available commercially？
66．What is"to go hands-free"？A
A．The new suitcase
B．Your cell phone．
C．Signals from your cell phone
D．Frequent travelers．
67．Which paragraph tells about how Hop works？B
A．Paragraph One
B．Paragraph Two
C．Paragraph Three
D．Paragraph Four．
68．The article is probably taken fromB．
A．Hop's official website                   
B．a(chǎn) website of worldwide news
C．a(chǎn) Western newspaper                   
D．a(chǎn) Chinese newspaper
69．According to the article，Hop may run into trouble becauseC．
A．your cell phone fails to tell you Hop is lost 
B．its caterpillar tracks aren't powerful enough
C．you usually walk too fast for Hop to follow   
D．TSA agents won't be patient enough
70．What does the writer think of the invention？D
A．Hop will be in production soon
B．Hop is sure to be popular someday．
C．It's silly to have thought of that
D．Hop might never go on sale．

5．Can you believe your eyes？A recent experiment suggests that the answer to that question may depend on your age．
   Martin Doherty，a psychologist at the University of Stifling in Scotland，led the team of scientists．In this experiment，Doherty and his team tested the perception（觀察力） of some people，using pictures of some orange circles．The researchers showed the same pictures to two groups of people．The first group included 151 children aged 4 to 10，and the second group included 24 adults aged 18 to 25．
   The first group of pictures showed two circles alone on a white background．One of the circles was larger than the other，and these people were asked to identify the larger one．Four-year-olds identified the correct circle 79 percent of the time．Adults identified the correct circle 95 percent of the time．
   Next，both groups were shown a picture where the orange circles，again of different sizes，were surrounded by gray circles．Here's where the trick lies in．In some of the pictures，the smaller orange circle was surrounded by even smaller gray circles--making the orange circle appear larger than the other orange circle，which was the real larger one．And the larger orange circle was surrounded by even bigger gray circles--so it appeared to be smaller than the real smaller orange circle．
   When young children aged 4 to 6 looked at these tricky pictures，they weren't fooled-they were still able to find the bigger circle with roughly the same accuracy as before．Older children and adults，on the other hand，did not do as well．Older children often identified the smaller circle as the larger one，and adults got it wrong most of the time．
   As children get older，Doherty said，their brains may develop the ability to identify visual context（背景）．In other words，they will begin to process the whole picture at once：the tricky gray circles，as well as the orange circle in the middle．As a result，they're more likely to fall for this kind of visual trick．
71．Doherty and his team of scientists did an experiment to evaluate．D
A．children's and adults'brains           
B．children's and adults'eye-sight
C．the influence of people's age         
D．people's ability to see accurately
72．When asked to find the larger circle，．C
A．a(chǎn)dults got it right most of the time with gray ones around
B．children at 6 got it wrong 79%of the time with no gray ones around
C．children at 4 got it right about 79%of the time with gray ones around
D．only adults over 1 8 got it right 95%of the time with gray ones around
73．According to the passage，we can know that．A
A．a(chǎn) circle surrounded by bigger ones looks smaller than its real size
B．a(chǎn)n orange circle appears bigger than a gray one of the same size
C．a(chǎn) circle surrounded by other circles looks bigger than its real size
D．a(chǎn) smaller orange circle appears bigger on a white background
74．Visual context may work when children get older than．B
A．4               B．6               C．10              D．18
75．Why are younger children not fooled？D
A．Because older people are influenced by their experience．
B．Because they are smarter than older children and adults．
C．Because people's eyes become weaker as they grow older．
D．Because their brains can hardly notice related things together．

3．Living with physical disabilities can be challenging in all kinds of ways．But different from what most parents think，physical disabilities are no barrier（障礙）to a child enjoying all the benefits that healthy exercise and outdoor play can bring．The importance of exercise has been stressed in recent years as the problems connected with being too fat and poor mental（精神的）health become ever more widespread．Being physically disabled does not mean that a child cannot be affected by these problems．And being active is a natural and fun way of preventing problems like these from having a bad influence．
A swimming pool is one of the best places possible for physically disabled children to enjoy themselves．With proper support，whether from parents or from correctly trained professionals，children can get great benefits from being in the pool．The water provides both support and resistance（阻力），giving a cardiovascular（心血管的）workout as well as making muscles strong．Being able to feel free in a way that is not possible on land is another benefit of swimming．
It is possible to play most ball games with a group of children in wheelchairs．Moving and dancing to music is a great social activity for physically disabled children as well as something parents call enjoy with children．A parent or carer can help the child move in time to music or show movements to the child．Playing a modified （調(diào)整的）form of volleyball with a lowered net means that children in wheelchairs can take part and healthy people can sit on chairs to play with them．
With some imagination，enjoying activities with a child who is disabled is not a problem．With access to some special equipment，children with physical disabilities do not have to be limited in how they play．

72．What do most parents think of the children with physical disabilities？B
A．They can't really enjoy their lives．
B．They can't enjoy physical activities．
C．They have to stay indoors to protect themselves．
D．They are more likely to become too fat．
73．What benefits can physically disabled children get from swimming？C
a．getting support from professionals
b．making their muscles stronger
c．doing good to their heart
d．enjoying themselves by feeling free
A．a(chǎn)cd    B．a(chǎn)bd    C．bcd    D．a(chǎn)be
74．Why is dancing a good form of exercise for physically disabled children？A
A．It can offer them a chance to socialize with others．
B．It is easy for them to copy the musical movements．
C．It is the only exercise that they can do without wheelchairs
D．It is the most common exercise that they can enjoy with their parents
75．The passage is written toC
A．tell disabled children the importance of exercise
B．teach parents how to treat their disabled children
C．encourage disabled children to take physical activities
D．call on people to pay more attention to disabled children．

10．An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients'life．Called the Biologic-HT System，the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body．The heated blood causes the patient's body temperature to rise above 42 degrees Celsius．In people with AIDS，that increase in temperature kills some heat-sensitive HIV，the virus，most doctors say，causes AIDS．
Heating the blood of AIDS patients has been tried before，say doctors．But during previous attempts，the treatment induced deadly chemical changes in the blood．The Biologic-HT System prevents those changes from happening，allowing the heat to kill viruses with few ill side effects．
The new heat treatment cannot be considered a cure for Aids，says president of the company that makes the system．He says the treatment doesn't kill all traces of the virus．However，it kills enough virus particles to give a patient's immune system a reprieve in its deadly duel with HIV．
Tests of the Biologic-HT treatment began on 36 patients earlier this year．The treatment takes about four hours，and the patient normally feels well enough to leave the hospital or clinic the following morning．
So far，the patients who have had the treatment say they feel better and have developed no new opportunistic infections-disease that strike people with damaged immune systems．The patients also have experienced about a 50 percent increase in the number of T cells in their bodies．T cells are key disease-fighting cells of the immune system and the main target of HIV．
36．This passage is mainly concerned withA．
A．a(chǎn) way for treating AIDS              
B．a(chǎn) heat-sensitive virus
C．the immune system of the human body
D．the function of high temperature
37．The blood of the patientD．
A．is heated with a single injection
B．is heated by being circulated at a higher rate
C．is taken out from the body and then circulated through a heating system．
D．is taken out from the body，heated outside and then put back into the body．
38．The previous attempts to use high temperature for treating AIDS failed because theyA．
A．caused chemical changes     B．could not kill HIV effectively
C．resulted in deaths          D．killed both HIV and healthy cells
39．According to the passage，the new treatment．B
A．can kill all the HIV viruses
B．cannot eliminate the viruses completely
C．can double the number of disease-fighting cells
D．can reconstruct the patient's immune system．
40．The result of the experiment seems to beC．
A．disappointing   B．incomplete   C．successful     D．surprising．

7．Asian parents are spending billions of dollars on private tutors （家庭教師） for their children and the practice is growing despite doubts about its effectiveness，according to an Asian Development Bank study published Wednesday，AFP reported．
"Shadow education"is an expanding business not only in wealthy countries，but also in some of the region's poorer nations as parents try to give their children the best start in life，the study said．Nearly nine out of 10 South Korean elementary pupils receive private tutoring，while the figure for primary school children in India's West Bengal state stands at six out of 10．
he study estimated that the costs of private tutoring in South Korea were equivalent （相等的） to 80 percent of government spending on public education．Japan spent 12 billion on extra teaching in 2011，while the figure for Singapore stood at US$ 680 million in 2009．
Extra academic work aims to help slow learners and support high achievers．Many Asian parents view it as a constructive way for adolescents to spend their spare time．However，it can also reduce the students'time for sports and other activities important for their overall development as well as cause social tensions as richer families are able to pay for better-quality tutoring，the study said．
The study calls for a review of educational systems to make such extra teaching less attractive．
56．Why is"Shadow education"an expanding business？D
A．Because parents want to spend their money．
B．Because children don't want to go to school．
C．Because parents want their children to stay with teachers．
D．Because parents want to give their children the best start in life．
57．According to the article，what is the purpose of extra academic work？A
A．To aid slow learners and support high achievers．
B．To prepare children for all kinds of academic contests．
C．To increase children's hobbies and interests in many fields．
D．To gain the most knowledge that students can't get in class．
58．Which disadvantage of extra academic work is NOT mentioned？C
A．Causing social tensions．
B．Spending more extra money．
C．Lacking the chance to communicate with others．
D．Reducing the students'time for sports and other activities．
59．What is the text mainly about？D
A．The government policy on educational systems．
B．How to provide the best education for children．
C．The importance for children's overall development．
D．The reasons for the popularity of private tutors for children．
