题型：不详难度：来源：
The robot is designed to snake through dark, narrow air conditioning ducts （管道） and clean them．A pair of LEDs fitted on the robot light up the dirty scenery, so it can be captured （抓拍） by a camera．
In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels．The robot can clean off lots of dirt, as well as dead pigeons and insects．Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge．It is important in some places where clean air can mean a difference between life and death, such as hospitals．Dirty air has a bad influence on people"s health．
EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad"s invention in a national newspaper after he had won an international robotics competition．EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work．Across India, for example, the task still falls to children．They are small enough to go through those ducts．
In 2005, Mr. Azad who was still at university decided to do something about it．Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners．
Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage （污水）pipes．Their biggest challenge is to make the robots user-friendly enough．Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers．There will be lots of difficulties they need to overcome in the future．

It is my understanding that this college has received a large donation to be used to improve the quality of life for students: expand the bookstore or add computers to the lab. I strongly argue in favor of the addition of more computers.
We have to think about a greater goal and a more practical way to enhance the quality of life for students. Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can research in their field using the best tools provided by technology?
As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future, since many students will be expected to be familiar with the latest software and other tools when they go on to work.
While they are in college, students find they are expected to use computers. They are asked to create PowerPoint presentations and research many topics on the Internet. Being able to do projects using the computer also gives students the opportunity to find information that without a computer would be much more difficult to find. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage.
If there are more new and faster computers accessible, students will be able to complete their work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and computer. No longer will they have to sit and wait while an outdated computer struggles to follow their commands.
The more computers are used in society, the more colleges will depend on them as a tool of teaching and learning. Making computers more accessible to students facilitates their learning process by making it much easier and more engaging(专注), and eventually improves their quality of life.
小题1:The purpose of the author in writing the passage is________.
| A．to explain why students are in great need of computers |
| B．to tell us what benefits students can gain from computers |
| C．to persuade the Dean to purchase more advanced computers |
| D．to describe the problems caused by lack of computers |
| A．computers are beneficial to students’ academic success |
| B．computers are the only access to good grades for students |
| C．students find it convenient to do homework by computers |
| D．students wish to use more money to buy more computers |
| A．furthers | B．equips | C．predicts | D．troubles |
A.  | B.  |
C. | D.  |
I welcome the kind of debate about the value of higher education.It is necessary to remember， however，that Ellsberg also tells how important it is to make money．He mentions a number of college dropouts一such as Bill Gates and Michael Dell一to show how successful they have become without the benefit of a college degree．While Ellsberg stresses the achievements of dropouts，he includes degree holders who have become wealthy and famous．For example，of the current Fortune 500 CEOs，some 99％have a college degree．Similarly，of the Forbes 400 richest people in America，81％hold postseconda.ry（高等）degrees.
But in the discussion，what is forgotten about the value is that the purpose of education is not simply to enable one to earn a living but to prepare one for living over the course of life ．What is also left out of the debate about higher education is that its purpose is not just to provide a pathway covered with gold for the nation’s elites（精英）．If we have the discussion that way，we may look down upon the people who devote themselves to other ordinary jobs that form the basic structures（结构）of our society，Though these individuals may not be reaching for the kind of stars that Michael Ellsberg and others would have them grasp，most are doing something even more important：they are involved in the useful tasks of good citizens and contributing to the common welfare，including providing for their families．

| C．most of the richest people received college education |
| D．success of dropouts proves the value of higher education |
| A．is keen on society charity work | B．calls for the equality of all man |
| C．speaks highly of the nation’s elites | D．shows respect to common people |
| A．persuade people to go to university |
| B．make a comment on a new book |
| C．complain about the college education |
| D．praise Michael Ellsberg for his hard work |
“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”
Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.
“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
小题1:According to the passage, a mom had better ________.
| A．give a kid some help when he is explaining his problem |
| B．just listen while a kid is explaining his problem |
| C．work together with a kid toward the solution to a problem |
| D．leave a kid alone when he meets a problem at school |
| A．should know the answer to a problem first |
| B．should pay attention to the child’s feedback. |
| C．may not know the answer herself |
| D．should not interrupt the child |
| A．The kid’s mom. |
| B．The kid’s grandmother. |
| C．A peer. |
| D．A relative the kid doesn’t know. |
| A．Children learn better when their mom is hearing their explaining. |
| B．Children learn better if they find the solution to a problem themselves. |
| C．Parents should not provide any assistance to their children’s schoolwork. |
| D．A mom should listen more to their children when they have problems at school. |
The study, conducted by neuroscientists (神经学家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “
小题1:From the second paragraph, we can learn that ________.
| A．women always speak more words than men |
| B．men and male rats have low levels of language protein |
| C．women and male rats have similar levels of Foxp2 |
| D．McCarthy isn’t the first to find females more talkative |
| A．paid attention to | B．related to | C．put pressure on | D．counted on |
| A．test which part of the brain is key to language in rats and humans |
| B．prove the levels of Foxp2 protein in humans and rats are different |
| C．determine the reason why female rats are more talkative than male rats |
| D．discover the association between Foxp2 protein and vocal communication |
| A．Tests on humans and rats |
| B．Why women are the talkative sex |
| C．Sex differences in Foxp2 protein |
| D．Foxp2 protein determines oral ability |
I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly (清晰地) a sign over her classroom door. It was a simple sign that said, “Laboratory—in this room the first five letters of the word was emphasized (强调), not the last seven.” In other words, I guess, labor for her was more important than oratory, which means making speeches.
She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.
I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit (有益于) the students.
小题1:Which of the following is considered a good teacher by the writer?
| A．A patient teacher. | B．An honest teacher. |
| C．A strict teacher. | D．A hard-working teacher. |
| A．to remind the students that this room was a laboratory |
| B．to advise the students to follow the disciplines |
| C．to warn the students not to be careless |
| D．to tell the students to work hard in the classroom |
| A．gave her students the usual amount of homework |
| B．gave her students less homework |
| C．asked her students to check the homework themselves |
| D．gave her students more homework |
| A．It makes the students dislike their teachers. |
| B．It does good to the students in the long run. |
| C．It’s too much for young children. |
| D．It does more harm than good to the students. |
