题目内容

Light travels（传播）at a speed which is about a million times faster than the speed of sound.In one second,light travels about 300,000 km,but sound travels only 344m.You can get some idea of this difference by watching the start of a race（比赛）.If you stand some distance away from the starter,you can see smoke come from his gun before the sound reaches your ears.This great speed of light produces（产生）some strange facts.Sunlight takes about 8 minutes to reach us.If you look at the light of the moon tonight,remember that the light rays（光线）left the moon 1.3 seconds

before they reached you.

The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute.In some cases（在某种情况下）the light from one of tonight's stars started on its journey to you before you were born.

Thus,if we want to be honest,we cannot say "The stars are shinning（发光）tonight."We have to say,"The stars look pretty.They were shining four years ago but their light has only just reached Earth."

Because six out of every 10 accidental deaths happen to Chinese children who are playing, Shanghai Johnson & Johnson Pharmaceutical (SJJP), a US?based pharmaceutical giant, is working on a Safe Kids Program to prevent injuries and deaths.

Since the Safe Kids Worldwide was set up in 1987 by Johnson & Johnson in the US, it has contributed to a nearly 40 percent decline in the child death rate from accidental injuries there.Learning from the successful experience, SJJP began the Safe Kids Program in China in 1999.

A recent survey conducted by SJJP and Safe Kids Worldwide China indicates that more than half of the responding parents didn't know how to help their children keep safe and that half of the parents didn't know about their children's motor skill development at different ages.The survey covered 3,359 Beijing, Shanghai and Guangzhou's parents with children between infancy (幼年) and 14.

Currently, a special team has been set up and traveling around 12 key cities of China to popularize child sports safety knowledge and offer free training for young parents.

Though SJJP refuses to say how much it has spent on the program, it says the number in terms of money, staff and technology, is large.

SJJP was founded by Johnson & Johnson in 1995 and specializes in manufacturing and development of non?prescription medicines (非处方药) and health care foods and products.So far，its investment has exceeded $41 million.
