Train companies in Tokyo are taking action to reduce the number of people jumping in front of trains．They are fitting blue lights on station platforms to try and create a more calming atmosphere．The East Japan Railway Company has invested almost$170,000 to install the lights in all of the 29 stations on the capital's busy Yamanote Line．There has been an alarming rise in the number of people committing suicide at train stations．A total of 68 people threw themselves under trains in the year up to March．This compares with 42 suicides in the same period a year earlier．In 2008,Japan had nearly 2,000 suicides by jumping in front of a train;around six percent of all suicides nationwide．Suicides have risen sharply in the past decade due to poor economic conditions.
No one knows if the blue lights will work．There is no evidence to show that blue light reduces suicidal feelings．Keihan Railway spokesman Osamu Okawa stated:"We thought we had to do something to save lives．We know there is no scientific proof that blue lights deter suicides,but if blue has a soothing effect on the mind,we want to try it to save lives."The Associated Press news agency reports on a Japanese therapist called Mizuki　Takahashi．She explained her reasons why the blue lights might be a good idea:"We associate the color with the sky and the sea．It has a calming effect on agitated people,or people obsessed with one particular thing,which in this case is committing suicide,"she said．Other companies are watching this experiment with interest.

A.has no result yet
B.is proved effective

The first true piece of sports equipment that man invented was the ball.
In ancient Egypt,as everywhere,pitching stones was a favorite children's game．But a badly thrown rock could hurt a child．Looking for something less dangerous to throw,the Egyptians made what were probably the first balls.
At first,balls were made of grass or leaves held together by vines．Later they were made of piece of animal skin sewed together and stuffed with feathers or hay.
Even though the Egyptians were warlike,they found time for peaceful games．Before long they had developed a number of ball games,each with its own set of rules．Perhaps they played ball more for instruction than for fun．Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.

This selection says that the Egyptians played__.

A.many different games with balls
B.many different kinds of games
C.only one ball game
D.different games with similar roles
