英语初高中衔接(含答案)
二、初高中英语衔接专题一：名词考点集汇，讲解和训练【名师点睛】一、名词的数1．单数和复数可数名词有单数和复数两种形式。
复数形式通常是在单数形式后加词尾“-s”构成，其主要变法如下：（1）一般情况在词尾加-s，例如：book→books，girl→girls，boy→boys，pen→pens,doctor→doctors, boy→boys。
（2）以s，x，ch，sh，结尾的词加-es，例如：bus→buses，class→classes box→boxes，watch→watc hes，brush→brushes。
（3）以ce, se, ze,（d）ge结尾的名词加s，例如：orange—oranges。
（4）以辅音母加y结尾的词变“y”为“i”再加-es,例如：city→cities, factory→factories, country→countries, family→families。
但要注意的是以元音字母加y结尾的名词的复数形式只加s，如：boy→boys, day→days。
（5）以o结尾的词多数都加-es。
例如:hero→heroes，potato→po tatoes，tomato→tomatoes,但词末为两个元音字母的词只加-s。
例如：zoo→zoos，radio→radios，还有某些外来词也只加-s，例如：photo→photos，piano→pianos。
（6）以f或fe结尾的词，多数变f为v再加-es，例如：knife→knives，leaf→leaves, half→halves。
复数词尾s（或es）的读音方法如下表所示。
复数词尾s（或es）的读音方法（7）少数名词有不规则的复数形式，例如：man→men，woman→women，tooth→teeth，foot→feet，child→children，mouse→mice。
110【注意】与man和woman构成的合成词，其复数形式也是-men和-women。

中考物理专题复习《初高中物理衔接类问题》练习
中考物理专题复习《初高中物理衔接类问题》牛顿第三定律、动能、重力势能、弹性势能、机械能守恒定律、实际电流表和理想电流表、单摆摆动周期、平抛运动、斜抛运动、万有引力、电场力、凸透镜成像规律、磁力等问题，在初中阶段都没有量化的表达，有的只是定性的说明，但初中课程教学中，有的只是经过拓展学习，初步的达到了和高中阶段所学内容十分接近，在知识和知识简衔接处，用到一定的物理方法就完全可以达到高中阶段所学知识的水平。
在中考中，为了选拔能力素养突出的学生，物理试题的命制就会以初高中衔接知识为素材。
所以毕业班学生多学习这些问题，中考成绩会更加突出。
一、牛顿第三定律1.作用力和反作用力：两个物体之间的作用总是相互的，一个物体对另一个物体施加了力，后一个物体同时对前一个物体也施加力.2. 牛顿第三定律内容：两个物体之间的作用力和反作用力总是大小相等、方向相反、作用在同一条直线上.理解要点：(1)作用力和反作用力相互依赖性，它们是相互依存，互以对方作为自已存在的前提；（2）作用力和反作用力的同时性，它们是同时产生、同时消失，同时变化，不是先有作用力后有反作用力；（3）作用力和反作用力是同一性质的力；（4）作用力和反作用力是不可叠加的，作用力和反作用力分别作用在两个不同的物体上，各产生其效果，不可求它们的合力，两个力的作用效果不能相互抵消，这应注意同二力平衡加以区别。
（5）一对平衡力与作用力、反作用力的比较二、机械能守恒定律（一）动能1．概念：物体由于运动而具有的能量，称为动能。
2．动能表达式：221υm E K =3．动能定理（即合外力做功与动能关系）：12K K E E W -=4．理解：①合F 在一个过程中对物体做的功，等于物体在这个过程中动能的变化。
②合F 做正功时，物体动能增加；合F 做负功时，物体动能减少。
③动能定理揭示了合外力的功与动能变化的关系。
5.适用范围：适用于恒力、变力做功；适用于直线运动，也适用于曲线运动。

初高中衔接型中考数学试题（4）
1. （杭州03改）把抛物线
c bx x y ++=2的图象向右平移3个单位，再向下平移2个单位，所得图象的解析式是
2(1)2y x =++，则有b= ，c= 。
2. （重庆03/8）已知：如图，梯形ABCD 中，AD ∥BC ，∠B ＝45°，∠C ＝120°，AB ＝8，
则CD 的长为（ ） A 、
638 B 、64 C 、238 D 、24
3. （2003资阳市）如图，在△ABC 中，已知∠ACB＝90°，CD⊥AB 于D ，AC ＝36，BD ＝3。
（1）请根据下面求cosA 的解答过程，在横线上填上适当的结论，使解答正确完整： ∵CD⊥AB ，∠ACB＝90°，∴AC ＝ cosA ， ＝AC·cosA，由已知AC ＝36，BD ＝3 ∴36＝AB cosA ＝（AD ＋BD ）cosA ＝（36cosA ＋3）cosA
设t ＝cosA ，则t ＞0，且上式可化为322t ＋ ＝0，则此解得cosA ＝t ＝
2
3 （2）求BC 的长及△ABC 的面积。
450
1200
D B
A
D C B A
4. （荆门03/19）（本题满分8分）（1）如图1，在△ABC 中，∠B 、∠C 均为锐角，其对
边分别为b 、c,求证：B b sin =C
c sin ； （2）在△ABC 中，AB=3，AC=2，∠B =450,问满足这样的△ABC 有几个?在图2中作出
来(不写作法,不述理由)并利用(1)的结论求出∠ACB 的大小。
A
B
C
A B C （图1） （图2） 19题图
参考答案
1、答：b=8，c=20。
分析：抛物线2(1)2y x =++的顶点是（－1，2），向左平移3个单位，横坐标－1变－4，
再向上平移2个单位，纵坐标2变4，顶点变为（－4，4），而抛物线的大小形状开口方向
都不改变，故解析式为2(4)4y x =++，即2
820y x x =++，与c bx x y ++=2比较得b=8，c=20。
点评：逆向思维，抓住关键，以“点”代线、从特殊到一般，是本题的解题策略。
2、答：A 。
3、答：（1）AB AD （2）
（2）解：在Rt △ABC 中，BC=AC ·tanA=36＝6
S △ABC =12AC BC ⋅=4、。
