  1.turn out/ off, turn on, turn down, turn up
  turn out/ off意思是“关掉”,常指关掉电器的电源或水龙头等。反义词组是turn on(打开)。表示“开大”是turn up,“关小”是turn down。例如:
  Please turn out/ off the TV. My baby is sleeping.
  请关掉电视。宝宝在睡觉。
  It’s so hot today. Could you please turn on the air-conditioner?
  今天天气真热。请打开空调好吗?
  He turned off/ out the computer and turned on the TV.
  他关上电脑,然后打开了电视。
  She is doing her homework. Turn down the TV, please.
  她在做功课。请把电视声音关小一点。
  值得注意的是,turn on,turn off/out, turn down与turn up都是动词加副词构成的词组,接代词时,要位于副词之前,接名词放在副词前后都可以。例如:
  There is something wrong with the blender. Don’tturniton.
  榨汁机有毛病。请不要打开。
  I can’t hear the news. Please turn up the radio/ turn the radio up.
  我听不见新闻。请把收音机开大一点。
  2.win, beat
  两者在表示“战胜,赢得,打败”这一意思时,后接宾语有所不同。beat后面的宾语是比赛对手,而win后面的宾语是match, game, war, prize, fame(荣誉)等名词。试比较:
  I can beat you at swimming.
  在游泳比赛中我能击败你。
  Who do you think can win the volleyballmatchintheend?
  你认为谁最终能赢得这场排球比赛?
  beat与win的反义词是lose,常用的结构是“lose(sth.) to sb.”,后接的宾语与win相同。例如:
  Welosttothe women’sfootball team.
  我们输给了女子足球队。
  3.at the end of, in the end
  at the end of 意为“在……末尾”“到……尽头”;in the end意为“最后”“终于”,用作状语。试比较:
  At the end of the term we shall have another exam.
  在学期末我们还有一次考试。
  Some of the students sat on the benches at the end of the room.
  有几个学生坐在房间尽头的长凳上。
  In the end I agreed to go.
  最后我同意去。
  Intheendhefoundoutallthe secret.
  他终于弄清楚了所有的秘密。
  4.alive, living, lively
  alive是表语形容词,作“活着的”“在世的”解,它既可以修饰人也可以修饰物。作定语时,应将其放在被修饰的名词后面。例如:
  She was still alive when I reached the hospital.
  当我赶到医院的时候她还活着。
  They caught a lion alive.
  他们活捉了一只狮子。
  living意为“活着的”,主要用作定语,常置于名词前。也可用作表语。例如:
  He is one of the greatest living scientists.
  他是健在的最伟大的科学家之一。
  lively读作[laivli],意为“生动的” “活泼的” “充满生气的”,用作表语或定语,可以用来修饰人或物。例如:
  She is a lively girl and popular with everyone.
  她是个活泼的姑娘,大家都很喜欢她。
  The boy has a lively mind.
  这男孩头脑灵活。
  He had a strange way of making his classes lively and interesting.

教育家叶圣陶先生说过:“语文教学成功与否,是要看学生最终能否离开教师自己读书、作文,掌握语文这一工具学科。”我想,作为老师的我们应该将打开文化宝库的钥匙交给学生,让学生做“春耕”的主人,从“学会”转变为“会学”。先哲说过:“吾生也有涯,而知也无涯 。”说的是人的生命是有限的,而知识是无穷的。不管一个人在学生时代如何勤奋,他也不可能把所有的知识全部学到手。踏入社会后,新的知识更是层出不穷。因此,为了

根据反比例函数的意义可知,两个变量与的乘积是一个常数(≠0).如图1,设P(,)是反比例函数 =图象上的任意一点,过P作轴、轴的垂线,垂足为A、B,则△OPA(或△OPB)的面积 = OA·PA = || =||,即矩形PAOB的面积等于||.   由此,我们得出系数的几何意义:过双曲线上任意一点P(,)分别作轴、轴的垂线,两垂线与坐标轴所围成的矩形面积为||.灵活运用此性质可以帮助我们快速简捷地
