Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners --- the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog，and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly，the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person.
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs，but won’t get rid of the need for human workers.

The scientific literature evaluating these techniques goes back to decades and across thousands of articles. It’s far too extensive and complex for the average parent, teacher or employer to look through. Fortunately, a team of five leading psychologists have done the job for us.
Professor John Dunlosky and other psychologists closely examined 10 learning strategies and rated each from high to low utility(实用) on the basis of the evidence they’ve gathered. Here’s part of their conclusions:
In contrast to familiar practices, the effective learning strategies with the most evidence to support them aren’t well known outside the lab. Take distributed practice, for example. This strategy involves spreading out your study time, rather than engaging in one marathon. Cramming (死记硬背）information at the last minute may allow you to get through that test or meeting, but the material will quickly disappear from your memory. It’s much more effective to look through the material at intervals over time.
And the longer you want to remember the information, whether it’s two weeks or two years, the longer the intervals should be.
The second learning strategy that is highly recommended by Dunlosky is practice testing. Yes, more tests---but there not for a grade. Research shows that the mere act of calling information to mind strengthens that knowledge and aids in future retrieval (检索). While practice testing is not a common strategy---despite the strong evidence supporting it ---there is one familiar approach that captures its benefits: using flash cards. And now flash cards can be presented in digital form. Both distributed practice and practice testing were rated as having “high utility” by Dunlosky.

Scientists have determined that the human finger is so sensitive it can detect a surface bump just one micron（l0－6m）"high． The human eye, by contrast, can"t tell anything much smaller than100 microns．No wonder we rely on touch rather than eyesight when faced with a new roll of toilet paper．
Biologically, touch is the mother of all sensory（感觉的） systems．It is an ancient sense in evolution: even the simplest single-celled living things can feel when something brushes up against them and will respond by moving closer or pulling away． It is the first sense aroused during a baby’s development and the last to weaken at life"s peak． Patients in a deep coma （昏迷）who seem otherwise lost to the world will show skin reaction when touched by a nurse．
“Touch ,is so central to what we are that we almost cannot imagine ourselves without it,” said Chris Dijkerman．“It"s "not like eyesight, where you close your eyes and you don"t see anything． You can"t do that with touch．It"s always there．"
Long ignored in favor of the sensory heavyweights of eyesight and hearing, the study of touch lately:: has been gaining new concern among scientists．They"re exploring the effects of recently reported false touch impressions, of people being made to feel as though they had three arms, for example, with the hope of gaining the true understanding of how the mind works．
Others are turning to touch for more practical purposes: to build better touch screen instruments and robot hands, a more well-rounded virtual life．。“There"s a fair amount of research into new ways of offloading information onto our sense of touch," said Lynette Jones． "To have your cell phone buzzing （making a low sound） as opposed to ringing turned out to have a lot of advantages in．some situations．"
Touch is our most active sense, our means of seizing the world and experiencing it "first hand． Dr．Susan Lederman pointed out that while we can become aware of something by seeing or hear,ing7;-．from a distance and without really trying, if we want to learn about something by means of touch, we must make a move．We must rub the cloth, or pet the cat． Touching is a two-way street, and that"s not true for seeing or hearing． If you have a soft object and you squeeze it, you change its shape． The physical world reacts back．"
Our hands are smart and can do many tasks automatically - button a shirt, fit a key in a lock, play the; piano for others．Dr．Lederman and her colleagues have shown that blindfolded subjects can easily recognize a wide range of common -objects placed．in their hands．But on some feeling tasks, touch is all thumbs （very clumsy）． When people are given a raised line drawing of a common object, they"re puzzled．“If all we"ve got is outline information;" Dr．Lederman said,．“no weight, no texture, no temperature information, well, we"re very, very bad with that．"
Touch also turns out to be easy to fool, Among the sensory tricks now being investigated is something called the Pinocchio illusion． Researchers have found that if they shake the band of the biceps（二头肌）, many people report feeling that their forearm is getting "longer, their hand floating ever further from their elbow（肘）． And if they are told to touch the forefinger of the shaken arm to the tip of their nose, they feel as though their nose was lengthening, too．

I asked about Timothy’s typical day. He awoke every morning at six thirty so he could reach his school by eight and arrived home around four thirty each afternoon. He then had a quick snack, followed by either a piano lesson or a lesson with his math tutor. He finished dinner at 7 pm, and then he sat down to do homework for two to three hours. Quickly doing the math in my head, I found that Timothy spent an average of thirteen hours a day at a writing desk.
What if Timothy spent thirteen hours a day at a sewing machine instead of a desk? We would immediately be shocked, because that would be called children being horribly mistreated. Timothy was far from being mistreated, but the mountain of homework he faced daily resulted in a similar consequence — he was being robbed of his childhood. In fact, Timothy had no time to do anything he truly enjoyed, such as playing video games, watching movies, or playing board games with his friends.
Play, however, is a crucial part of healthy child development. It affects children’s creativity, their social skills, and even their brain development. The absence of play, physical exercise, and freefrom social interaction takes a serious toll on many children. It can also cause significant health problems like childhood obesity, sleep problems and depression.
Experts in the field recommend the minutes children spend on their homework should be no more than ten times the number of their grade level. As a fifthgrader, Timothy should have no more than fifty minutes a day of homework (instead of three times that amount). Having an extra two hours an evening to play, relax, or see a friend would soundly benefit any child’s life quality.
小题1:What did the writer think of Timothy after learning about his typical day__________?
| A．Timothy was very hardworking. |
| B．Timothy was being mistreated. |
| C．Timothy had a heavy burden. |
| D．Timothy was enjoying his childhood. |
| A．Children should be allowed enough time to play. |
| B．Playing board games works better than playing video games. |
| C．The more they play, the more creative children will become. |
| D．The depression caused by homework makes children unwilling to play. |
| A．About ten minutes. | B．No more than twenty minutes. |
| C．No more than thirty minutes. | D．About fifty minutes. |
Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, “Year-round schools don"t really solve the problem of the summer learning setback. They simply spread it out across the year.”
Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.
But calling them “summer school” could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term “summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like “summer camp”, “enrichment”, “extra time” and “hands-on learning”.
小题1:According to the first paragraph the summer learning gap .
| A．helps children to gain weight |
| B．leads children to work harder |
| C．improves children’s memories |
| D．affects children’s regular studies |
| A．perform better and have more learning gains |
| B．have much less time for relaxation every year |
| C．have generally the same number of class days |
| D．hold more classes with more free weeks off |
| A．Students from poor families often fall behind after the vacation. |
| B．Year-round schools can solve the problem of the learning gap. |
| C．There are schools in each state following a year-round calendar. |
| D．Nothing can help the students who fall behind after the vacation. |
| A．They cherish the children’s rights of freedom very much. |
| B．They are worried about the quality of the “summer school”. |
| C．They want their children to be forced to make up the gap. |
| D．They can’t afford the further study during vacation. |
| A．Opening Summer Camps |
| B．Forbidding Summer Schools |
| C．Spreading Year-Round Education |
| D．Minding the Summer Learning Gap |
"Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
"Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded.
小题1:According to the passage, students who date in middle school may_____
| A．have poorer academic performances |
| B．be more likely to hurl others |
| C．enjoy better school lives |
| D．are less likely to use alcohol and tobacco |
| A．followed a group of students of 6th and 12th grade |
| B．completed a survey and a report each year |
| C．completed questionnaires about the students’ academic efforts |
| D．found that the students’ study skills have connection with their frequency of dating |
| A．being diligent | B．being well organized |
| C． being kind and helpful | D．finishing assigned schoolwork |
| A．They don’t want to see each other any longer. |
| B．Their attention to studying will be affected. |
| C．They will miss their ex-partners sometimes |
| D．They will think it reasonable to get depressed. |
| A．supportive | B．positive | C．negative | D．indifferent |
