You probably don’t know as much as you think you do. When put to the test, most people find they can’t explain the workings of everyday things they think they understand. Don’t believe me? Find an object you use daily (an ear phone, a toilet, a stereo speaker) and try to describe how it works. We call this phenomenon the illusion of explanatory depth(解释性深度错觉). It means you think you fully understand something that you actually don’t.
We see this every day in buzzwords (流行语). Though we often use them, their meanings are usually unclear.
Several years ago, I attended a meeting where the president spoke about global business practice in the coming year. During the talk, people around the room nodded in agreement. Afterwards, though, many of them discussed how to manage global business practice, none of the people who had nodded in agreement could exactly describe what it actually meant.
No matter what job you do, discovering your gaps in knowledge is necessary. An unknown gap means you might not fully understand a problem.
To discover the things you can’t explain, take a lesson from teachers. When you guide someone else, you have to fill the gaps in your own knowledge. But you don’t need to teach someone else. Explain concepts to yourself as you learn them. Get in the habit of self-teaching. Involve others in learning together. Ask them to explain difficult concepts, even if you think everyone understands them. Not only will this help you to work through new ideas, but it will occasionally uncover places where your friends don’t understand the explanations.
They can help you have a better understanding of problems.
| A．An active learner usually puts it into reality. |
| B．That can prevent you from solving the problem properly. |
| C．Your explanations can’t show your own knowledge gaps. |
| D．Help recognize the knowledge gaps of the people around you. |
E. You’re likely to discover unexpected gaps in your knowledge.
F. They cover gaps in our knowledge, serving concepts we don’t fully understand.
G. When you do uncover these gaps, treat them as learning opportunities, not signs of weakness.

In many parts of the world, cars play an important role in daily life and many societies would not exist without them. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. That will mean much saving, no accidents and better use of roads. The super-intelligent car in the future will drive itself.
Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says, cars will be fitted with some intelligent devices(装置) to regulate(调节) the distance between one car and another. computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen. Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.”says Davis. “but all the others in the train would burn about ten percent of the normal amount, and so produce about ten percent of the pollution.”
| A．The team there believes that by 2030 all cars will be computerized. |
| B．They believe that cars will become more important in 20 years. |
| C．And it will not be owned by one individual. |
| D．And by 2030, cars will travel in line, linked to each other electronically. |
E.So the idea that in 20 years’ time, no one will own cars may be hard to believe.
F.Every driver will use less fuel in the car he owns.
G.The car will automatically speed up, or slow down, to match the speed of the car in front.
