[单项选择]There is one kind of pain for which nobody has yet found a cure--the pain that comes from the ending of a relationship. The relationship could be a marriage or a deep friendship. Such a relationship may come to a sudden end; or it may simply fade away slowly as people and circumstances change. You may be the one to "break it off’, with a short note or a brief phone call. Or you may be on the receiving end. However it ended and whoever decided to end it, the pain is equally hard to bear and it requires the same time for grief. Although there is no cure for grief, we can not help looking for one, to ease the pain and to make us forget our tears. We keep ourselves busy with work, or we try to plunge ourselves into our hobbies. Perhaps we start to drink more than we should to "drown our sorrows", or we follow the conventional advice and join a club or society. But these things cannot cure it. Moreover, we are always in a hurry to get rid of our grief. We feel that we should try to convince
A. how to erase the emotional pain
B. what is the emotional pain like
C. what cause the emotional pain
D. why to erase the emotional pain

A new kind of radar has been developed for spaceship travelers. A working laboratory model of a new system of radar that makes use of a beam of light is said to be ten thousand times more accurate than the best comparable system of radar that used microwaves.
The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops—speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship’s skin, or a nudge could knock the station out of its orbit.
The light-beam radar, which operates at a frequency of trillions (百万兆) of cycle
A. measures the movements of a spaceship by means of light beam
B. makes use of microwaves
C. makes use of sound waves
D. Both A and B
