(沪教版)初二下册英语知识点 ◆unit 3 What were you doing when the UFO arrived? 知识点: 1.过去进行时 a) 过去进行时由“was/were+动词ing形式”构成。以动词work为列,其肯定式,否定式,疑问式以及简略答语见下表: 肯定式:I/He/She/It was working. We/You/ They were working. 否定式:I/He/She/It was not working. We/You/They were not working. 疑问式和简略答语:Was I working? Yes, you were. Was he working? No, he wasn’t. 【注意】was not常简略为wasn’t; were not常简略为weren’t b) 过去进行时的用法:过去进行时表示过去某一时刻或某一段时间正在进行的动作。这一特定的过去时间,除有上,下文暗示以外,一般用时间状语来表示2.not …until直到…才。表示动作在某时之前尚未开始,直到此时动作才开始。not…until可以用after或when来代替,但主句谓语动词要用肯定形式。Until 为连词时后接时间状语从句,until作介词时,后面接表示时间的名词。Until 用于肯定句多表示动作或状态一直延续到until所表示的时间为止,意思为“直到…” from..till…中till往往表示不太具体的时间。From …to…或from…until常用来表示具体的时间。 3.find it…to do,it在此句中为形式宾语代表动词不定式,动词不定式为真正的宾语,常用于这种用法的动词有find, feel, think, make等。 4.“疑问词+不定式“结构相当于一个名词性从句,常常可用同等成分的从句代替。改写时,只需在疑问词后面加一个适当的主语(这个主语一般与主句的主语一致),并将不定式改成适当形式的谓语即可。如,Where to go is still a question.=

沪教版八年级数学下知识点总结

沪科版八年级数学下知识点总结 二次根式知识点: 知识点一:二次根式的概念 形如()的式子叫做二次根式。 注:在二次根式中,被开放数可以是数,也可以是单项式、多项式、分式等代数式,但 必须注意:因为负数没有平方根,所以是为二次根式的前提条件,如,,等是二次根式,而,等都不是二次根式。 知识点二:取值范围 1. 二次根式有意义的条件:由二次根式的意义可知,当a≧0时,有意义,是二次根式,所以要使二次根式有意义,只要使被开方数大于或等于零即可。 2. 二次根式无意义的条件:因负数没有算术平方根,所以当a﹤0时,没有意义。 知识点三:二次根式()的非负性 ()表示a的算术平方根,也就是说,()是一个非负数,即0()。注:因为二次根式()表示a的算术平方根,而正数的算术平方根是正数,0的算术平方根是0,所以非负数()的算术平方根是非负数,即0(),这个性质也就是非负数的算术平方根的性质,和绝对值、偶次方类似。这个性质在解答题目时 应用较多,如若,则a=0,b=0;若,则a=0,b=0;若,则a=0,b=0。知识点四:二次根式()的性质 () 文字语言叙述为:一个非负数的算术平方根的平方等于这个非负数。 注:二次根式的性质公式()是逆用平方根的定义得出的结论。上面的公式 也可以反过来应用:若,则,如:,. 知识点五:二次根式的性质 文字语言叙述为:一个数的平方的算术平方根等于这个数的绝对值。 注: 1、化简时,一定要弄明白被开方数的底数a是正数还是负数,若是正数或0,则等于a本身,即;若a是负数,则等于a的相反数-a,即; 2、中的a的取值范围可以是任意实数,即不论a取何值,一定有意义; 3、化简时,先将它化成,再根据绝对值的意义来进行化简。 知识点六:与的异同点 1、不同点:与表示的意义是不同的,表示一个正数a的算术平方根的平方,而表示一个实数a的平方的算术平方根;在中,而中a可以是正实数,

沪教版八年级数学上下册总结

八年级数学 第十六章 二次根式 第一节 二次根式的概念和性质 二次根式 1. 二次根式的概念: 式子)0(≥a a 叫做二次根式.注意被开方数 只能是正数或O . 2. 二次根式的性质 ①? ??≤-≥==)0()0(2a a a a a a ; ②)0()(2≥=a a a ③)0,0(≥≥?=b a b a ab ; ④)0,0(>≥=b a b a b a 最简二次根式与同类二次根式 1. 被开方数所含因数是整数,因式是整式,不含能开得尽方的因数或因式的二次根式,叫做最简二次根式. 2.化成最简二次根式后,被开方数相同的二次根式,叫做同类二次根式 二次根式的运算 1.二次根式的加减:先把各个二次根式化成最简二次根式,再把同类三次根式分别合并. 2.二次根式的乘法:等于各个因式的被开方数的积的算术平方根, 即 ).0,0(≥≥=?b a ab b a

3.二次根式的和相乘,可参照多项式的乘法进行. 两个含有二次根式的代数式相乘,如果它们的积不含有二次根式,那么这两个三次根式互为有理化因式. 4.二次根式相除,通常先写成分式的形式,然后分子、分母都乘以分母的有理化因式,把分母的根号化去(或分子、分母约分).把分母的根号化去,叫做分母有理化. 二次根式的运算法则: c c c≥0) ?b a b a ab = ≥ ).0 ,0 (≥ a a =a≥0,b>0) b b =( a≥0) ()n n a a

第十七章 一元二次方程 一元二次方程的概念 1.只含有一个未知数,且未知数的最高次数是2的整式方程叫做一元二次方程 2.一般形式y=ax 2+bx+c (a ≠0),称为一元二次方程的一般式,ax 叫做二次项,a 是二次项系数;bx 叫做一次项,b 是一次项系数;c 叫做常数项 一元二次方程的解法 1.特殊的一元二次方程的解法:开平方法,分解因式法 2.一般的一元二次方程的解法:配方法、求根公式法 3.求根公式24b b ac x -±-=:221244b b ac b b ac x x -+----= , = ; △=24b ac -≥0 一元二次方程的判别式 1.一元二次方程20(0)ax bx c a ++=≠: △>0时,方程有两个不相等的实数根 △=0时,方程有两个相等的实数根 △<0时,方程没有实数根 2.反过来说也是成立的 一元二次方程的应用 1.一般来说,如果二次三项式2ax bx c ++(0a ≠)通过因式分解得2ax bx c ++=12()()a x x x x --;1x 、2x 是一元二次方程20(0)ax bx c a ++=≠的
