Dreams may be more important than sleep. Some people don’t need much sleep. But we all need to dream, scientists say.
Dreams take up about one quarter of our sleeping time. People have several dreams each nigh -t. Dreams are like short films. They are usually in color. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.
Some people get new ideas about their work from dreams. They could have been thinking about their work all day. These thoughts can carry over into dreams.
Sometimes we wake up with a good feeling from a dream. But often we can’t remember the dream. Dreams can disappear quickly from memory. Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is hard at working when we dream. That is why we may have a long sleep and still wake up tired.
( ) 51. It may be less important to sleep than to _______.
A. think
B. dream
C. work
D. study

八年级上册期末试卷测试卷附答案 一、八年级数学全等三角形解答题压轴题（难） 1．（1）已知△ABC是等腰三角形，其底边是BC,点D在线段AB上，E是直线BC上一点，且∠DEC=∠DCE,若∠A等于60°（如图①）.求证：EB=AD； （2）若将（1）中的“点D在线段AB上”改为“点D在线段AB的延长线上”，其他条件不变（如图②），（1）的结论是否成立，并说明理由． 【答案】（1）证明见解析（2）证明见解析 【解析】 试题分析：（1）作DF∥BC交AC于F，由平行线的性质得出∠ADF=∠ABC，∠AFD=∠ACB，∠FDC=∠DCE，证明△ABC是等边三角形，得出∠ABC=∠ACB=60°，证出△ADF是等边三角形，∠DFC=120°，得出AD=DF，由已知条件得出∠FDC=∠DEC，ED=CD，由AAS证明 △DBE≌△CFD，得出EB=DF，即可得出结论； （2）作DF∥BC交AC的延长线于F，同（1）证出△DBE≌△CFD，得出EB=DF，即可得出结论. 试题解析：（1）证明：如图，作DF∥BC交AC于F， 则△ADF为等边三角形 ∴AD=DF，又∵∠DEC=∠DCB， ∠DEC+∠EDB=60°， ∠DCB+∠DCF=60°， ∴ ∠EDB=∠DCA ，DE=CD， 在△DEB和△CDF中， 120 EBD DFC EDB DCF DE CD ， ， ∠=∠=? ? ? ∠=∠ ? ?= ? ∴△DEB≌△CDF， ∴BD=DF， ∴BE=AD . (2).EB=AD成立；
理由如下：作DF∥BC交AC的延长线于F，如图所示： 同（1）得：AD=DF，∠FDC=∠ECD，∠FDC=∠DEC，ED=CD， 又∵∠DBE=∠DFC=60°， ∴△DBE≌△CFD（AAS）， ∴EB=DF， ∴EB=AD. 点睛：此题主要考查了三角形的综合，考查等边三角形的判定与性质，全等三角形的判定与性质，等腰三角形的判定与性质，等腰直角三角形的判定与性质，平行线的性质等知识，综合性强，有一定的难度，证明三角形全等是解决问题的关键. 2．（1）如图（1），已知：在△ABC中，∠BAC＝90°，AB=AC，直线m经过点A，BD⊥直线m, CE⊥直线m,垂足分别为点D、E.证明:DE=BD+CE. （2）如图（2），将（1）中的条件改为：在△ABC中，AB=AC，D、A、E三点都在直线m 上,并且有∠BDA=∠AEC=∠BAC=α,其中α为任意锐角或钝角.请问结论DE=BD+CE是否成立?如成立,请你给出证明;若不成立,请说明理由. （3）拓展与应用：如图（3），D、E是D、A、E三点所在直线m上的两动点（D、A、E 三点互不重合）,点F为∠BAC平分线上的一点,且△ABF和△ACF均为等边三角形，连接BD、CE,若∠BDA=∠AEC=∠BAC，试判断△DEF的形状. 【答案】（1）见解析（2）成立（3）△DEF为等边三角形 【解析】 解：（1）证明：∵BD⊥直线m，CE⊥直线m，∴∠BDA＝∠CEA=900． ∵∠BAC＝900，∴∠BAD+∠CAE=900． ∵∠BAD+∠ABD=900，∴∠CAE=∠ABD． 又AB="AC" ，∴△ADB≌△CEA（AAS）．∴AE=BD，AD=CE． ∴DE="AE+AD=" BD+CE． （2）成立．证明如下：
