Pigs are always considered dirty animals because they roll in mud．But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．So do elephants, who also cover themselves in dust or mud to keep cool．When they find a place with clean water they will take a bath，using their long noses to give  themselves—or each other—a nice shower

Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don’t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease

Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth  cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any  parasites(寄生虫)between the crocodile’s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．

You wouldn’t think fish would need baths．But some undersea parasites live under the  fish’s skin．“Cleaner” fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．

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（地位相当者） 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 are more likely to rank “having fun” higher on their list of priorities．Women are 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 have reported increased confidence, self-reliance（自立） and independence, whereas only half of the men had that experience．
The research also shows that women are more likely to do voluntary work while travelling, 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 face objections or criticism from their families over their gap­year plans．Among the men surveyed, lack of money is the main barrier to travel．
Carolyn Martin, a doctor from London,is 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”．
【小题1】By referring to “gap year” the writer means ________．  

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（地位相当者） 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 are more likely to rank “having fun” higher on their list of priorities．Women are more likely to value the challenge of a foreign trip, and many cited reasons such as learning a language and meeting new people．
