5、y children?阅读理解 women staying in mini-skirts for longer阅读判断 across the desertsthe sahara desert is the largest desert in the world. it stretches across africa from senegal to egypt. the sahara desert is an unfriendly environment. during the day its very hot, and at night its sometimes very cold. it
6、is also difficult to find water in the sahara.in 2006, kevin lin, ray zahab, and charlie engle decided to do something very difficult. they made the decision to run across the sahara desert 4,300 miles (6,920km). it seemed impossible to do, but they wanted to try. the three men liked to test themsel
7、ves, and this would be a very big test.on the morning of november 2, kevin, ray, and charlie started their trip across the sahara. every morning they began running at 5:00. at11 a.m. they stopped and rested until 5 p.m. then they ran again until 9:30 in the evening. each day they ran about 40 miles
8、(64 km). every day it was the same thing. they got up and ran. they listened to music on their ipods, and they ran and ran.kevin, ray, and charlie needed to eat a lot of food during their trip. most people need about 2,000 calories of food each day. kevin, ray, and charlie needed between 6,000 and 9
9、,000 calories every day. thats a lot of food! they also needed to drink a lot of water.the three men had some problems on their trip, and many times they wanted to quit and go home. it was often very hot (140f/60c) during the day, and the heat made them sick. their legs and feet hurt. sometimes it w
10、as very windy, and they couldnt see. one time they got lost. but they didnt quit. after 111 days, kevin, ray; and charlie successfully finished their trip across the sahara desert. they hugged each other and put their hands in the water of the red sea. then they ran to a hotel to take a long shower.

15、found a reason why. the dogs weaknesslies in its social organization.within each pack of up to 20 adultsand pups, only the dominantmale and female breed. the remaining animals help raise the pups, cooperatingto hunt prey and defend the kill from other carnivoresbecause pups cant keep up on a hunt, l
16、arge packs leave an adult behind to protect them from predators, which include lions and hyenas . but leaving a babysitter also carries costs . a smaller hunting party is less able to tackle large prey and to defend the kill. there is also one less stomach in which to carry food back to the den and
17、one more mouth to feed when they get there.courchamp investigated this awkward trade-off by modeling how the costs of a babysitter change with decreasing pack size. this showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. but with smaller pack
18、s , either the hunting or the babysitting suffers , or the animals have to compensate by increasing the number of hunting excursions - which itself carries a cost to the pack.field observations in zimbabwe supported the model. packs of five animals or fewer left pups unguarded more frequently than l
19、arger packs did. there was also evidence that when they did leave a babysitter, they were forced to hunt more often.a pack which drops below a critical size becomes caught in a vicious circle , says courchamp, who is now at paris-sud university. poor reproduction and low survival further reduces( pa

23、y see. say goodbye to the greetings of the past, from the hands-off “whats up!” to the handshake or high-five. for young people across the country, hugging is the new “hello”. girls are hugging girls. boys are hugging boys, girls and boys are hugging each other. and, like every major trend, there ar
24、e lots of variations on the form. theres the classic, full-body, arms-around-the-person bear hug, the casual one-armed side hug, the group hug and the hug from behind, theres the handshake that turns into a hug that turns into a pat on the back. as trends go, this one seems pretty innocent. but some
25、 parents, teachers and school administrators and worried nonetheless. will young people who arent as comfortable with physical contact feel peer pressured into hugging? will kids who dont receive hugs feel left out? could an extra-long hug slide into the more ominous territory of sexual harassment?
26、in response to some of these concerns, some schools have set up new rules to limit or eliminate hugging. one school head has created a three-second limitation for hugs at her school. a few schools have taken even more drastic measures, placing a ban on all forms of touching between students. a few i
27、mportant points are being left out of the discussion. while the us has traditionally been reserved about touching-saving hugs and kisses for relatives, romantic partners and very close friends-people in many other parts of the world have been greeting each other this way for ages. in latin american
28、or western europe, in countries like spain, france, and italy, a kiss on the cheek is common among women, as well aw among women and men who are not romantically involves. the cheek-kiss varies by region. sometimes it is just an air kiss blown past the face. in other places, the proper way of greeti
29、ng is to deliver a kiss upon both cheeks, or sometimes even a triplet of kisses performed by kissing one cheek, then the other, then back to the first. latin american men are more likely to shake hands when greeting other men, but in some countries like turkey, its not unusual for men who know each

52、the institute views as opposition and indifference from school boards and government entities. the institute believes that the teaching of evolution in america is being diminished by the teaching of creationism as well as by an overall lack of teaching darwins theory in high school. “theres nothing
53、that requires schools to teach evolution. sometimes teachers in high schools just leave it out. however from the point of view of biologists, evolution is the central theory of biology upon which everything is based,” said weis. “unfortunately, teaching evolution has become a political issue in many
