针对训练
3、若5x2 y与x m yn是同类项,则m=2( ) ,n=1( ) 若5x2 y与x m yn的和是单项式,则m=2( ) , n=1( )
只有同类项才 能合并成一项
考点三 去括号
例3 已知A=x3+2y3-xy2,B=-y3+x3+2xy2, 求:(1)A+B;(2)2B-2A. 【解析】 把A,B所指的式子分别代入计算. 解:(1)A+B=(x3+2y3-xy2)+(-y3+x3+2xy2)
5.绝对值 (1)一个数在数轴上对应的点到原点的距离 叫做这个数的绝对值 (2)一个正数的绝对值是它本身.
一个负数的绝对值是它的相反数. 0的绝对值是0.
6.有理数大小的比较 (1)数轴上表示的两个数,右边的总比左边的大. (2)正数大于0,0大于负数,正数大于负数;
两个负数,绝对值大的反而小.
三、有理数的运算 1.有理数的加法
例4 若A是一个三次多项式,B是一个四次多项式,
则A+B一定是( B )
A.三次多项式 B.四次多项式或单项式
C.七次多项式
D.四次七项式
【解析】A+B的最高次项一定是四次项,至于是否含 有其它低次项不得而知,所以A+B只可能是四次多项式或 单项式.故选B.
你能举出对应 的例子吗?
针对训练
5.若A是一个四次多项式,B是一个二次多项式, 则A-B( ) C

There are some apples on the tree. 树上有些苹果。
this&that; these&those 这四个词是指示代词。this,that是单数形式,意为 “这个,那个”;these, those 是复数形式,意为“这 些,那些”。this 和 these 表示近指,指近处的事物; that和those表示远指,指远处的事物。 例如:This is a black cat. 这是一只黑猫。

Is this/ that my backpack? (一般疑问句)
—Where is my schoolbag? —It’s under the sofa. 句型 “Where + be + 主语(人或物)?” 用来询问某 人或某物在哪个地方。where’s 是where is的缩写形 式;where意为“在哪里”,be要随着后面主语的变化 而变化变化,主语是单数时用is,复数时用are。这 个句子是特殊疑问句,因此回答时不能用yes或no, 而是要回答具体的内容。 例如:—Where’s my hat? 我的帽子在哪儿?
—It’s on the desk. 在桌子上。 —Where are my shoes? 我的鞋在哪里? —They’re under my bed. 在我的床底下。
