七年级下错题收集(一)

七年级下册数学易错题50道一、相交线与平行线1. 判断题：不相交的两条直线叫做平行线。

（错误）解析：必须是在同一平面内不相交的两条直线才叫做平行线，如果不在同一平面内，不相交的直线不一定平行。

2. 若∠1与∠2是同旁内角，∠1 = 50°，则∠2的度数是（）A.50°B.130°C.50°或130°D.不能确定答案：D解析：两直线平行，同旁内角互补；两直线不平行，同旁内角的关系不确定，只知道∠1 = 50°，不知道两直线的位置关系，所以∠2的度数不能确定。

3. 如图，AB∥CD，直线EF分别交AB、CD于点E、F，EG平分∠BEF，若∠1 = 72°，求∠2的度数。

解：因为AB∥CD，∠1 = 72°，所以∠BEF = 180°∠1 = 180°-72° = 108°。

因为EG平分∠BEF，所以∠BEG=公式∠BEF=公式。

又因为AB∥CD，所以∠2 = ∠BEG = 54°。

二、实数4. 公式的平方根是（）A.2B.±2C.4D.±4答案：B解析：先计算公式，然后求4的平方根，因为公式，所以4的平方根是±2。

5. 下列说法正确的是（）A.无限小数都是无理数B.带根号的数都是无理数C.无理数是无限不循环小数D.实数包括正实数和负实数答案：C解析：无限循环小数是有理数，A错误；公式是有理数，B错误；无理数是无限不循环小数，C正确；实数包括正实数、0和负实数，D错误。

6. 计算：公式解：公式，公式，公式。

则原式公式。

三、平面直角坐标系7. 点P（m + 3，m + 1）在x轴上，则点P的坐标为（）A.（0，-2）B.（2，0）C.（4，0）D.（0，-4）答案：B解析：因为点P在x轴上，所以P点的纵坐标为0，即m + 1 = 0，解得m=-1。

一、选择题1. 错题：下列哪个数是负数？A. -3B. 0C. 3D. 5错误答案：B正确答案：A解题过程：在数轴上，负数位于0的左侧，因此-3是负数。

2. 错题：下列哪个数是正数？A. -3B. 0C. 3D. 5错误答案：C正确答案：D解题过程：在数轴上，正数位于0的右侧，因此5是正数。

3. 错题：下列哪个数是有理数？A. √2B. πC. -1/2D. 无理数错误答案：A正确答案：C解题过程：有理数是可以表示为两个整数比的数，因此-1/2是有理数。

二、填空题1. 错题：下列哪个数是整数？A. -3.14B. 0.5C. 3D. √9错误答案：A正确答案：C解题过程：整数是没有小数部分的数，因此3是整数。

2. 错题：下列哪个数是无理数？A. √2B. πC. -1/2D. 3错误答案：B正确答案：A解题过程：无理数是不能表示为两个整数比的数，因此√2是无理数。

三、解答题1. 错题：已知a=2，b=-3，求a+b的值。

错误答案：-5正确答案：-1解题过程：a+b=2+(-3)=-12. 错题：已知x=3，求x^2-5x+2的值。

错误答案：4正确答案：-7解题过程：x^2-5x+2=3^2-53+2=9-15+2=-7总结：通过整理错题集，我们可以发现自己在学习过程中的不足，及时进行复习和巩固。

同时，了解自己的错误原因，有助于提高解题能力。

在今后的学习中，我们要认真对待每一道题目，总结经验，不断提高自己的数学水平。

B.癞头僧看见英莲，乃指着她大笑，口内念了四句言词道：惯养娇生笑你痴，菱花空对雪澌澌，好防佳节元宵后，便是烟消火灭时。

七下科学作业本A错题集（含答案）AP1－9：女性发育到青春期，卵巢才开始形成成熟的，如果中遇到精子，就可能。

10.形成一个受精卵需要（）A．一个精子和一个卵细胞B．两个精子和一个卵细胞C．多个精子和一个卵细胞D．多个精子和多个卵细胞AP2－14.受精卵形成后，一边进行，一边沿着往下移动，进入子宫。

随着分裂次数的增加，受精卵逐渐形成了，并附着在上，这时女性就怀孕了，也称为。

16.对已生育的育龄妇女可通过结扎输卵管达到节育目的，结扎输卵管的作用是（）A.减少雌性激素分泌量，是卵细胞不能正常发育B.使精子和卵细胞不能相遇，不能完成受精作用C.使受精卵不能移至子宫，从而不能发育为胎儿D.使卵巢不能产生卵细胞，从而无法形成受精卵（答案：B ）（陈娅）17.通常情况下，卵巢每次只排一个卵细胞，少数情况会一次排两个卵细胞，两个卵细胞都受精，形成两个受精卵，每个受精卵各自发育成一个胎儿，形成双胞胎。

由于这样的双胞胎是又两个卵细胞分别受精发育而来的，故称为双卵双胎。

有时一个受精卵经过分裂后形成两个细胞，而这个细胞就像两个受精卵一样，各自发育成一个胎儿，这种情况称为一卵双胎。

根据以上叙述，可以知道双胞胎可以由个受精卵发育而来。
