……
The current prototype looks like a normal ear door, but an extra metal bar runs through its centre and connects to the ear’s flame between the hinges. In normal mode, the bar moves freely and doesn’t affect the door’s movement.
However, if sensors detect a nearby obstacle at the same time as an accelerometer (加速度讲; 加速仪) detects an attempt to open the door, the door’s swing is restricted by a linear motor attached to the bar.
The design of the intelligent door is designed in such a way that the door becomes hard to open when
A. there is an obstacle nearby.
B. there is something wrong with the accelerometer.
C. there is something wrong with the sensors.
D. there is an accelerometer in the car.

Accidents was caused; they don’t just happen. The reason may be easy to see: a shelf out of reach, a patch of ice on the road, an overloaded truck. But merely often than not there is a chain of events leading up to the misfortune—frustration, tiredness or just bad temper—that show what the accident really is, a sort of attack on oneself.
Road accidents, for example, happen frequently after a family quarrel, and we all know people who are accidents-prone, so often at odds with themselves and the world that they seem to cause accidents for themselves and others.
By definition, an accident is something you can not predict or avoid, and the idea which used to be current, that the majority of road accidents are caused by a minority of criminally careless drivers, is not supported by insurance statistics. These show that most accidents involve ordinary motorists in a moment of carelessness or thoughtlessness.

A. mood
B. tiredness
C. carelessness
D. weather
