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.

The use of blue lights to reduce suicides__.

A.has no result yet
B.is proved effective
C.is welcomed by suicides
D.has been refused by stations

Social customs and ways of behaving change．Things which were considered impolite many years ago are now acceptable．Just a few years ago,it was considered impolite behaviour for a man to smoke on the street．No man who thought of himself as being a gentleman would make a fool of himself by smoking when a lady was in a room.
Customs are also different from country to country．Does a man walk on the left or the right of a woman in your country?Or doesn't it matter?What about table manner?Should you use both hands when you are eating?
The Americans and the British not only speak the same language but also share a large number of social customs．For example,in both America and England people shake hands when they meet each other for the first time．Also,most Englishmen will open a door for a woman or offer their seat to a woman,and so will most Americans．Promptness is important both in England and in America．That is,if a dinner invitation is for 7 o'clock,the dinner guest either arrives close to that time or calls up to explain his delay.
The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable--especially if they are your guests．There is an old story about a man who gave a dinner party．When the food was served,one of the guests started to eat his peas with a knife．The other guests were amused or shocked,but the host calmly picked up his knife and began eating in the same way．It would have been bad manners to make his guest feel foolish or uncomfortable.

A.The guest who ate his peas with a knif
B.The other guests who were amused or shocke
C.The host who picked up his knife and began eating in the same wa
D.None of the abov
