2. c根据课文第9-10行he explained that his diet was so strict that he had to reward himself occasionally 可以判断只有c. hasn’t kept to a strict diet(没有严格的控制饮食)是课文所暗示的情况，而其他3个选择都不符课文的实际内容。

3. d只有选d. is 才能使这个句子的意义和时态同前一句相协调. a. was 时态不对. b. has 不是系动词,不能跟形容词.c. has been 时态不对,表示"他现在仍然很胖",没有必要用现在完成时.4. d本句的时间状语是How long ago 表示过去的时间，因此应该用一般过去时。

合并同类项练习题及答案【篇一：初一合并同类项经典练习题】、典型例题代数式求值例1 当x?2,y?时，求代数式x2?xy?y2?1的值。

例2 已知x是最大的负整数，y是绝对值最小的有理数，求代数式2x3?5x2y?3xy2?15y3的值。

例3已知合并同类项例1、合并同类项（1）(3x-5y)-(6x+7y)+(9x-2y)（2）2a-[3b-5a-(3a-5b)]（3）(6m2n-5mn2)-6(m2n-mn2)解：（1）(3x-5y)-(6x+7y)+(9x-2y)=3x-5y-6x-7y+9x-2y （正确去掉括号）=(3-6+9)x+(-5-7-2)y （合并同类项）=6x-14y（2）2a-[3b-5a-(3a-5b)] （应按小括号，中括号，大括号的顺序逐层去括号） =2a-[3b-5a-3a+5b] （先去小括号）=2a-[-8a+8b] （及时合并同类项）=2a+8a-8b （去中括号）=10a-8b教师寄语：如果想要看得更远，那就需要站在巨人的肩膀上！1 12122?2a?b?3?a?b?2a?b的值。

??5，求代数式a?ba?b2a?b （3）(6m2n-5mn2)-6(m2n-mn2) （注意第二个括号前有因数6） =6m2n-5mn2-2m2n+3mn2 （去括号与分配律同时进行）=(6-2)m2n+(-5+3)mn2 （合并同类项）=4m2n-2mn2例2．已知：a=3x2-4xy+2y2，b=x2+2xy-5y2求：（1）a+b （2）a-b （3）若2a-b+c=0，求c。

解：(1）a+b=(3x2-4xy+2y2)+(x2+2xy-5y2)=3x2-4xy+2y2+x2+2xy-5y2（去括号）=(3+1)x2+(-4+2)xy+(2-5)y2（合并同类项）=4x2-2xy-3y2（按x的降幂排列）（2）a-b=(3x2-4xy+2y2)-(x2+2xy-5y2)=3x2-4xy+2y2-x2-2xy+5y2 （去括号）=(3-1)x2+(-4-2)xy+(2+5)y2 （合并同类项）=2x2-6xy+7y2 （按x的降幂排列）（3）∵2a-b+c=0∴c=-2a+b=-2(3x2-4xy+2y2)+(x2+2xy-5y2)=-6x2+8xy-4y2+x2+2xy-5y2 （去括号，注意使用分配律）=(-6+1)x2+(8+2)xy+(-4-5)y2 （合并同类项）=-5x2+10xy-9y2 （按x的降幂排列）例3．计算：（1）m2+(-mn)-n2+(-m2)-(-0.5n2)（2）2(4an+2-an)-3an+(an+1-2an+1)-(8an+2+3an)（3）化简：(x-y)2-(x-y)2-[(x-y)2-(x-y)2]解：（1）m2+(-mn)-n2+(-m2)-(-0.5n2)=m2-mn-n2-m2+n2 （去括号）=(-)m2-mn+(-+)n2 （合并同类项）（2）2(4an+2-an)-3an+(an+1-2an+1)-(8an+2+3an)=8an+2-2an-3an-an+1-8an+2-3an （去括号）=0+(-2-3-3)an-an+1 （合并同类项）=-an+1-8an（3）(x-y)2-(x-y)2-[(x-y)2-(x-y)2] [把(x-y)2看作一个整体]教师寄语：如果想要看得更远，那就需要站在巨人的肩膀上！2=(x-y)2-(x-y)2-(x-y)2+(x-y)2 （去掉中括号）=(1--+)(x-y)2 （“合并同类项”）=(x-y)2例4求3x2-2{x-5[x-3(x-2x2)-3(x2-2x)]-(x-1)}的值，其中x=2。
