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 tha

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.
