looking for,"she said.Her husband had been part of the rescue operation.Today,safe at home,Brian still misses the welcome he received."Everyonc was veryhappy everywhere I went,"he says.He recalls the way the village's elders came to meethim-the man who had survived in the wild,and the man who had refused to give up.24.Why did Brian Koonoon climb a hill?A.To search for a way to the nearest village.B.To find his tracks in the snow.C.To let the airplane see him.D.To receive a radio signal.25.For what reason did Brian decide to walk to Repulse Bay?A.It was the closest way home.B.There was a rescue team there.C.He could turn to others for help there.D.He could keep in contact with his family there.26.What do we know about Brian s adventure from the text?A.A rescue team found him in the end.B.It took him about four days to arrive at Repulse Bay.C.He dragged the bag with the stove and a tent to head for the village.D.He only had 15 miles left to reach the village after a good sleep.27.What can we infer from the last paragraph?A.Brian's not giving up was respected by the villagers.B.Brian was proud of his courage to survive.C.Brian considered his experience a horrible one.D.Brian was unwilling to take an adventure again.If you're a fan of hummingbirds(),then you probably know that at night they lowertheir body temperatures greatly by dropping into an energy-saving state of inactivity calledtorpor().A new study finds that the birds have more than one level of torpor."Therehave been a few signs that this ability to fine-tune thermoregulation(温度调节)1 s possible,”said the lead author Anusha Shankar.Shankar and her colleagues used a special method to track the body temperatures of threehummingbird species in Arizona:the blue-throated mountaingem,Rivoli's hummingbird,and theblack-chinned hummingbird.They measured the temperatures emitted from the skin around the eyesof the birds and found that differences in heat generation at various stages are noticeable.The normal daytime body temperaturc of a hummingbird is more than 100 F,even incold weather.During shallow torpor,their body temperature drops by about 20 F.In deeptorpor,the bird keeps a body temperature 50 F below its normal daytime temperature.Ifhuman body temperature were to drop mere 3 degrees from the standard 98.6 F,we'd be in astate of hypothermia(低体温症)and,unlike hummingbirds,we would need outside help toget warm again."In this study,we found that the smallest bird used deep torpor every night,"saidShankar."The bigger birds sometimes use deep torpor and sometimes shallow torpor,andsomctimes no torpor at all.Shallow torpor may have developed to balance energy saving with the cost of deep torpor.In deep torpor,a hummingbird is much more likely to be affected by disease because itsimmune system(免疫系统)shuts down..And what's more,it would get inadequate sleep andbe easily harmed by its enemies.Torpor is not the same as sleep.Sleep uses much more energy and serves many importantfunctions.Daily torpor also differs from hibernation().Hibernating animals enter a low-energy state for weeks or months at a time,while hummingbirds can enter torpor every night.But the researchers say their studies were done under laboratory conditions,not the conditionsa bird would encounter in the wild.They say more research is needed to understandthermoregulation in birds.23031A
