题型:不详难度:来源:
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car"s gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard (车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car"s batteries will last for around 200,000 miles.

Five star fathers and their children travel around China, riding camels through the western deserts, fishing off the east coast, and selling vegetables for their bus fare home in remote southwestern Yunnan province. One dad doesn’t know how to do his daughter’s hair, but give him a couple of days — he’ll figure it out. Another one must survive with his son for three days in the desert, where, because neither can cook, the two only eat instant noodles.
These story lines are part of Where Are We Going, Dad? which, since its first show in October, has become one of China’s most popular television shows, covering more than 600 million viewers each week. And searches for Where Are We Going, Dad? turn up over 40 million hits on Sina Weibo, China’s Twitter.
“In traditional Chinese culture, the common conception of parenthood is that the father is strict and the mother is kind. But on the show, we see fathers who are much gentler on their kids and more concerned with their upbringing,” said Li Minyi, an associate professor of early childhood education at the leading Beijing Normal University. “An important question arises in this show for modern Chinese society — what is the role of fathers in today’s China?”
“As they raise their children, parents are growing up at the same time,” said Wang Renping, a popular education expert, in an interview with the Qianjiang Evening News. “They cannot use parenting styles from 20 years ago to guide the development of children born 20 years later.”
The attraction of Where Are We Going, Dad? lies in the chance to have a close look at the lives of popular Chinese stars and their children. Audiences fancy watching the failed attempts of star dads making dinner, braiding hair(编头发), and disciplining children — tasks often left to mothers in a society still influenced by the opinion that “men rule outside and women rule inside.”
小题1:From the passage, we can draw a conclusion that Where Are We Going, Dad? is .
A.a TV show | B.a novel | C.a match | D.a news report |
A.how the fathers do housework at home |
B.how the children study in their spare time |
C.how the fathers look after and guide their children |
D.how the children help their father with their travel around China |
A.In modern society, men should not care too much about their kids. |
B.Where Are We Going, Dad has the most number of viewers in China. |
C.In Chinese tradition, fathers always play an active part in their children’s lives. |
D.While they bring up their children, parents are improving their parenting styles. |
A.audiences enjoy laughing at others’ failure in life |
B.it can make people laugh and think at the same time |
C.people love watching the stars and their children’s lives closely |
D.it presents a new generation of men’s role in their children’s lives |
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.
小题1:What can we learn about Ductbot?
A.It is a toy car and popular with children. |
B.It is designed to move like a snake in the ducts. |

C.Azad"s difficulties are impossible to overcome. |
D.Azad"s team are working to improve their robot designs. |
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.
小题1:In the book The Education of Millionaires,Michael Ellsberg___.
A.approves of the value of education |

A.the value of higher education is never challenged |
B.higher education ensures people making more money |
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. |
