The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超声的) pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音调) and volume(音量) with the size and distance of the object.
The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny’s sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound(超声波) passes its edges. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. “From the first time he wore it,” says Mrs. Daughters, “it was like a light going on in his head.”
What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment.
Meanwhile, Telesensory, Inc, is working on the development of sonar(声纳) device with somewhat the same sensitivity as Dennis’s for use by school-age children.
小题1:Dr. and Mrs. Daughters’ research is directed to ________.
| A．helping the blind to see and learn as well as others |
| B．benefiting the learning process of blind children |
| C．solving blind children’s psychological problems |
| D．finding out how children develop intellectually |
| A．he already lags behind the sighted children |
| B．he leads a life as normal as any other children |
| C．he is at the early stage of the learning process |
| D．he has the aid of a sonar-type electronic device |
| A．Its first design was designed for blind adults. |
| B．Its battery is as small as a half-dollar coin. |
| C．It is functionally similar to a sane and guide dog. |
| D．It has been improved by Telesensory Systems, Inc. |
| A．the edge of an object |
| B．the edge of the device |
| C．the boundary of Dennis’ movement |
| D．the boundary of the sound pitch. |
答案
小题1:B
小题2:C
小题3:A
小题4:A
解析
试题分析：本文主要介绍了一项针对盲童学习过程的研究。
小题1:细节理解题。首段第三句末的不定式“to prevent a lag(滞后) in the learning process”表明了Daughters夫 妇研究的目的是为了使盲童的学习过程受益。另外，文章一开头就提到了本文讨论的重点是针对blind baby的，由此可见，选项B为本题答案。
小题2:细节理解题。首段首句提到的“a blind baby”，第三句提到的“ten months old”和末句提到的“infant” 等词都表明Dennis成为研究对象是因为Daughters夫妇 研究的是盲童从小的学习过程，Dennis年龄很小，正处 于学习的最初阶段，符合Daughters夫妇做研究的条件， 因此选项C为本题答案。
小题3:细节理解题。第二段首句中的“improvement”表 明Dennis用的声呐定位仪是Sonicguide的改良版，也就是说Sonicguide是Dennis的声呐定位仪的原型，根据该句对其功能的描述The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog.可以确定Dennis用的声呐定位仪原来是为盲人成年人使用的，选项A为本题答案。
小题4:细节理解题。第三段第四句中的“thanks to”表 明此处解释了Dennis的声呐定位仪的运作机制，即通 过声波描绘物体的形状，该句中the cone指的就是该定 位仪，而its edge应指周围物体的边缘，当声波碰到物体的边缘时，就能通过声音描绘出物体的形状了，因此本题答案应为A。

The plan and suggestions for its implementation will be announced in the first half of next year. It will be piloted in selected provinces and cities and promoted nationwide from 2017. A new exam and admission system will be established by 2020, according to the education ministry.
The decision has aroused a heated discussion among Shanghai educators and parents who doubted the reform would reduce the burden of learning English or if the substitute test could reflect a student’s English skills and help students learn English better.
“The reform shows China is learning from the West to give students more test-taking chances. But more chances might become more of a burden since Chinese students are likely to repeat the test until they get the highest score,” said Cai Jigang, a professor at Fudan University’s College of Foreign Languages and Literature and chairman of the Shanghai Advisory Committee for College English Teaching at Tertiary Level.
Yu Lizhong, chancellor of New York University Shanghai, where classes are in English and students are required to have a high standard of English, said the most important aspect of the reform lay in what to test and how to test.
“ As far as I see, the reform doesn’t mean English is no longer important for Chinese students after it will be excluded from the unified college entrance exam,” Yu said. “In a way, English is even more important than before since the test would only serve as reference, while every college and university, even every major, can have different requirements of a student’s English skills under a diverse evaluation system. ”
Yu said some students will have their study pressure reduced if the major they choose doesn’t need excellent English while others still need to study hard if they want to be among the best students.
The education ministry said the reform would not affect students attending the college entrance exam over the next three years.
小题1:What can we learn from the first paragraph?
| A．English will become less and less important in the stage of compulsory education. |
| B．It has been 30 years since English became one subject of national college entrance exam. |
| C．China’s once-in-a-lifetime exam system is unacceptable at all. |
| D．The system that tests are held several times does more good than once-in-a-lifetime exam system. |
| A．the new exam and admission system will make no difference |
| B．English shouldn’t be removed from China’s college entrance exam |
| C．the reform may accomplish the very opposite |
| D．Western educational system does not apply to China |
| A．Students needn’t lay a good foundation during the period of high school. |
| B．Whether students should study hard English may depend on their major. |
| C．Students can constantly strive for perfection only in their major. |
| D．English must be close to full mark. |
| A．To advise students not to devote themselves to English. |
| B．To call on Education Department to remove English from “Gaokao”. |
| C．To support the act of Ministry of Education. |
| D．To encourage students to do as they have planned. |
But something is happening to their children. Up until the age of two they develop normally. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse(诅咒)of Silicon Valley,” but the medical name for the condition is autism(自闭症). It used to be thought that autism was a kind of mental illness. Now doctors are sure that it is a neurological disease transmitted genetically. It seems that the people leading the communications revolution are having children who cannot communicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome is a mild version of autism. People who have it are highly intelligent and often brilliant with numbers or system but have no social skill. This very combination of symptoms makes Asperger’s sufferers into ideal computer professionals.
The Asperger’s sufferer has always been a well—known figure in popular culture. He or she was the eccentric but dedicated scholar or the strange uncle or auntie who never married. But the high numbers of such people in Silicon Valley mean that they can meet others who understand them and share their interests. And while they might not be personally attractive, they can earn truly attractive amounts of money. They can get married and have kids. Unfortunately, many of the children of two Asperger’s parents seem to be developing serious autism.
There is little anyone can do. It takes hours of work just to make autistic child realize that anyone else exists. And there is no cure in sight. Some argue that no cure should be found. “It may be that autistics are essentially different from normal people, but that these differences make them invaluable for the evolution of the human race,” says Dr. Kirk Whilhelmsen of the University of California. “To eliminate the genes for autism could be disastrous. ”
It seems that the children of Silicon Valley are paying the price of genius.
小题1:What does Dr Kirk Whilhelmsen think of autism?
| A．It is disastrous to society. |
| B．It is not completely a bad thing. |
| C．It is a punishment to those working in Silicon Valley. |
| D．People with autism should never marry. |
| A．It is believed to be a king of mental illness that can be cured. |
| B．People with autism can’t find people sharing their interests. |
| C．They do not care about the presence of others. |
| D．They are a burden for the society. |
| A．Because autistic people live in Silicon Valley. |
| B．Because many people working in Silicon Valley have autism children. |
| C．Because people with autism will be driven out of Silicon Valley. |
| D．Because people with autism are not personally attractive and not liked by others. |
| A．Asperger’s sufferers are ideal computer professionals. |
| B．Asperger’s sufferers never get married and have children. |
| C．Asperger’s sufferers are ashamed of themselves and locked into their own world. |
| D．Asperger’s sufferers can be beneficial to society if they are cured. |
Here are some tips you can use during your kids exam time.
Break their revision plan down into small parts. Doing this will help transform what once seemed like a huge impossible task into a more manageable one.
Help them arrange properly so that the subjects they like the least (perhaps ones that require more time and effort) are worked on first; once they are out of the way, it will help reduce the worry.
Plan week on week to make sure they are on track. Ticking items of a list each week will help them to feel good about themselves and their progress.
Create rewards for all the ticks - a favourite TV programme, a delicious snack, an hour’s surfing the Internet, computer games or whatever it was that they enjoy the most. This will encourage them to carry on and make them feel good.
Think of strategies on how to deal with exams calmly so their anxieties don"t get the better of them.
Talk about times in their lives when they had been successful at something and look at the qualities they used to get them there - determination, persistence, hard work, patience, positivity, dedication - discuss how they can apply these skills to their exams.
Acknowledge that if they do their best that is good enough.
Ensure they realize that this period in their lives will pass and that exams are only a temporary time in their lives; nothing can and does last forever.
Ensure they keep their eye on the prize: enjoying their long summer holiday when the exams are finished; giving them something to look forward to will help to motivate them and provide a positive end in sight.

But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite (冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits, according to the study. Some plants, such as oak trees, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions of years of evolution. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat of climate change.
小题1:What is the article mainly about?
| A．Why plants are not afraid of the winter chill. |
| B．The ways that plants survive cold weather. |
| C．Changes in plants’ water transport system in winter. |
| D．How plants evolve to keep up with climate change. |
| A．it produces more living tissues to stay alive |
| B．its leaves quickly fall out and its roots begin to die |
| C．lots of air bubbles form in its water transport system |
| D．its water transport system could be blocked in the spring |
| A．By dropping their leaves before winter. |
| B．By narrowing their water transport cells. |
| C．By widening their water transport cells. |
| D．By leaving only the seeds alive and growing from the seeds in the spring. |
| A．Plants may not be able to adapt to the increasingly cold climate. |
| B．Human activities might have a great impact on the pace of plants’ evolution. |
| C．Plants may not be able to evolve fast enough to adapt to human-caused climate change. |
| D．The strategies plants develop are not good enough to protect them against cold. |
