10、dren who slept for shorter periods at night were more likely to be associated with borderline personality disorder at ages 11 and 12.The research,published in the journalJAMA Psychiatry,was the first time possible links between early childhood sleep problems and adolescent psychotic experiences and
11、borderline personality disorder(BPD)symptoms have been examined.“We know from previous research that persistent nightmares in children have been associated with both psychosis and borderline personality disorder,”said lead author Isabel at theInstituteofMental Healthat theUniversityofBirmingham.“But
12、 nightmares dont tell the whole story.Weve found that,in fact,a number of behavioral sleep problems in childhood can point towards these problems in adolescence,”she said.Adolescence,typically defined as the ages between 10 and 19,is a key period in human development because of brain and hormonal ch

19、vefigured out how to tap into that movement to produce electricity.Picture a pendulum(摆锤)fixed to a backpack frame and stabilized with springs on either side.The packs weight is attached to the pendulum,so the pendulum swings side to side as you walk.Then a machine is driven by that swinging movemen
20、t,and spits out electrical current to charge a battery.Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O2and CO2.Walking with the slightly swinging 20-pound load,the device(设备)did not significantly affect the volunteers metabolic(新陈代谢的)rate compar
21、ed to when they carried the same weight fixed in place.In fact,the energy-harvesting pack reduced the forces of acceleration theyd feel in a regular pack,which might mean greater comfort for a long hike.And the device did produce a steady trickle(涓流)of electricity.If you up the load to 45 pounds,the
22、 swing of the pack could fully charge a smart phone only after 12 hours.The details are in the journal Royal Society Open Science.The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices.
23、It is particularly useful for those who work in remote areas,as these people often carry a lot of weight in a backpack for their exploration.But heres a realconundrum:the energy-harvesting device currently weighs five pounds.The researchers say thats about four pounds too many to be a smart alternat
24、ive to batteries.So they hope that more research lets them lighten the load,to ensure the pack charges you up without weighing you down.8.What does Paragraph 2 mainly talk about?A.How the device works.B.What the device looks like.C.Who the device is designed for.D.Why scientists designed the device.
25、9.Which of the following describes the device?A.It greatly affected the volunteers metabolic rate.B.It harvested energy as the volunteers walk.C.It failed to produce steady electricity.D.It was useless for a long walk.10.What does the underlined word“conundrum”in the last paragraph mean?A.Problem.B.
