Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,000km, but sound travels only 344m. You can get some idea of this difference by watching the start of a race. 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 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 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 shining tonight.” We have to say, “ The stars look pretty. They were shining four years ago but their light has only just reached Earth.”

Young women are more adventurous than young men when travelling abroad in gap years. One in three female backpackers visits more than three countries during a year out and travels alone, according to new research.
By contrast, the majority of their male counterparts visit only one country and tend to travel in groups, says a survey by the Gap Year company, which provides information and services for students considering taking a year out.
More women than men say that their prime reason for taking time off is to see the world and experience different cultures. Men were more likely to rank “having fun” higher on their list of priorities. Women were more likely to value the challenge of a foreign trip, and many cited reasons such as learning a language and meeting new people.
The more adventurous gap years taken by women seem to work to their benefit: more than three quarters of those surveyed reported increased confidence, self-reliance and inde??pendence, whereas only half of the men had that experience.
The research also showed that women were more likely to do voluntary work while trav??elling, with more than one in ten helping with teaching or development projects. One of the reasons given for this is a wish to see the country in an authentic light.
A greater proportion of women than men faced objections or criticism from their fami??lies over their gap-year plans. Among the men surveyed, lack of money was the main barrier to travel.
Carolyn Martin, a doctor from London, was a typically confident female traveller.
Starting in Cape Town, she travelled around southern Africa and Australia with a string of
unusual and sometimes dangerous jobs.
“I had one job chasing elephants off the runway in Africa by banging a stick against a pan,” she recalled. “It was OK but one day I did get chased by one.”
She said that she had travelled alone because “you meet more people”.
