The universe works in a way so far (remove) from what common sense (would) allow (that) words of any kind must necessarily be inadequate to explain (it).

A new kind of machine (21) to take the place of humans. These machines can do jobs that are too dangerous for humans. (22) , they are being developed to work in nuclear power centers, deep waters and outer space.
This is how the new machines work. A machine is placed in an area far away from the person who controls it. The person wears a special hard hat with tiny television screens. The screens (23) the person see and hear exactly what the machine is seeing and hearing. This gives the person the feeling of being in the same place (24) the machine. The person controls the machine. The machine follows the person’s movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an (25) worker can do a dangerous job while (26) in a safe place. For example, a person can direct the machine (27) a bomb (28) gooing near the bomb himself.
The new machines are not exactly (29) robots. Robots are controlled by a computer. The new machines are controlled by a person. The new machines are called teleoperators. The nuclear power industry is especially interested in teleoperators. The machines could solve the problem of (30) radioactive materials.

Motoring Technology ? ?1.2 million road deaths worldwide occur each year, plus a further 50 million injuries. To reduce car crash rate, much research now is focused on safety and new fuels, though some electric vehicle and biofuel research aims at going faster. ? ?Traveling at speed has always been dangerous. One advanced area of research in motoring safety is the use of digital in-car assistants. They can ensure you don’t miss important road signs or fall asleep. Most crashes result from human and not mechanical faults. ? ?Some safety developments aim to improve your vision. Radar can spot obstacles in fog, while other technology "sees through" big vehicles blocking your view. ? ?And improvements to seat belts, pedal (脚踏)controls and tires are making driving smoother and safer. The color of a car has been found to be linked with safety, as have, less surprisingly, size and shape. ? ?But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations(创新). Satellite tracking and remote communications can also come into play if you crash, automatically calling for help. ? ?Accidents cause many traffic jams, but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road. Such jams can be analyzed using statistical tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur(司机) , but their latest efforts suggest that won’t be soon. |
A:reduce oil consumption B:remove the obstacles on the road C:call for help when one’s car crashes D:help drivers get out of a traffic jam
In 1976 more than 500 people contracted an autoimmune disease called Guillain - Barresyndrome after receiving swine - flu shots in response to a small outbreak in Fort Dix, N. J. Some people understandably fear a repeat of that tragic episode, However, vaccine, production techniques have changed since then. Today, vaccines are highly purified to eliminate any potential contaminants. In addition, scientists use only selected viral proteins in the shots, not the entire virus, as they did in the 1970s. "The public is comparing this vaccine to the 1976 swine--flu vaccine," says CDC spokesperson Abbigail Tumpey. "In fact, the best comparison is to the seasonal vaccines of the last ten years. "
Nowadays ,vaccines are highly purified to
A:remove people’s fear for vaccine. B:avoid repeating the tragic episode in 1976. C:get rid of any possible contaminants. D:improve vaccine -production techniques.
