一、选择题
1．A
解析：A
【解析】
【分析】
【详解】
句意：我不能开我爸爸的车，除非我拿到了我自己的驾照。
考查连词辨析。unless=if not除非，引导条件状语从句；because因为，引导原因状语从
句；if如果，引导条件状语从句；since自从，引导时间状语从句；也可以作“因为，由于”讲，引导原因状语从句。我拿到驾照是我能够开车的条件，因此B、D选项错误，由于前面是否定形式，因此如果没有驾照就不能开车，也就是填if not=unless，故选A。
2．B

【解析】
【详解】
句意：这个问题是如此的难以至于我们很少有人能回答。
考查such……that句型。quite相当，后面接形容词原形；so如此，后面接形容词或副词，与that构成so……that句型“如此……以至于”；such如此，后面接名词或名词短语；very非常，后面接形容词或副词，根据所给空后面的a difficult question是名词短语，所以用such，故选C。

解析：D
【解析】
【分析】
【详解】
句意：这个小女孩正在哭，因为她找不到她的父母了。
考查连词。根据句意可知，小女孩哭的原因是找不到父母了，所以后句表示哭的原因。and 并列连词，并且；but并列连词，但是，表示转折；so连词，因此，表示结果；because连词，因为，表示原因。根据句意，故选D。
7．A
解析：A

9．A
解析：A
【解析】
【分析】
【详解】
句意：——聚会怎么样？——太精彩了，好多年了我没玩的这么高兴过。
此题是考查句型：It’ s years + since + 一般过去式，此题中的动词是enjoyed延续性动词，应从动作结束算起，可以翻译成它的反义词，故选A。
10．A
解析：A
【解析】
【分析】
【详解】

11．D
解析：D
【解析】
句意：--我们应该坐公交车去上学而不要坐小汽车。--是的，我们用的车越少，对环境的污染就越少。这里句式：the+比较级+主语+谓语，the+比较级+主语+谓语，表示“越……，就越……”。few修饰可数名词的复数，第一空修饰可数名词cars,所以应该用fewer；第二空pollution是不可数名词，用little的比较级修饰。故选D。
12．C
解析：C
【解析】
【详解】
句意：当这个女士听到这个消息时，她如此高兴，以至于她说不出任何话。
考查连词辨析。too…to+动词原形，表示“太……不能……”；so…that+结果状语从句，表示“如此……以至于……”；very…because+原因状语从句，表示“非常……因为……”。根据句意，第一个空格所在句子表示“这个女士是高兴的”，第二个空格所在句子表示“她说不出任何话”，可知，第二个空格所在句子表示的是结果，所以空格处用引导结果状语从句的连词so…that。故选C。
13．C
解析：C
【解析】
【分析】
【详解】
句意：蒂姆和他的双胞胎兄弟一样高，他们都有180厘米高。
考查as…as的用法。taller than比……高；shorter than比……矮；as tall as 和……一样高；not so tall as不和……一样高。根据第二句中“They are both 180 centimeters tall.”可知，他们都有180厘米高，所以此处是“蒂姆和他的双胞胎兄弟一样高”，所以使用as tall as符合题意。故选C。
【点睛】
本题考查的是as…as结构的用法，as与as之间既可以用形容词也可以用副词，而且是形容词或副词的原形，其否定形式为not a s/so…as，例如：He is as tall as his sister. He doesn’t run as fast as his sister.
14．A

【分析】
【详解】

15．B
解析：B
【解析】
【分析】
【详解】
句意：——你为什么卖旧书？——我卖书是为贫困学生筹集一些钱。
考查连接词。in order that为了，后接目的状语从句；in order to为了，后接动词不定式作目的状语；so that以便，后接目的状语从句；because of介词短语，为了，后接名词或者动名词。根据句意可知，卖旧书的目的是为贫困学生筹款，表示目的，且空格后接动词原形，不是从句，故可知是不定式作目的状语。故选B。
16．B
解析：B
【解析】
【分析】
【详解】
句意：格林先生没有任何爱好，除非你把看电视称为爱好。

25．B
解析：B
【解析】句意：如果你挑战某人，你会邀请他们去战斗或者和他们在某方面竞争。A. encourage鼓励；B. challenge挑战；C. introduce介绍。根据句意：你邀请他们去战斗或者和他们在某方面竞争，可知是“如果你挑战某人”，“挑战”challenge。分析题干可知这是if引导的条件状语从句，要遵循“主将从现”的原则，所以if从句要用一般现在时，故答案选B。

二年级下册数学易错题分析 第一单元解决问题 错例1 题目描述： 典型错解： 错因分析： 学生在解决问题的过程中，对于用两种方法解决问题有所误解，认为像综合算式48-7+12=53（人）和分式48-7=41、41+12=53（人）两种算式的形式不一样就是两种列式的方法，没有将其与解决问题的思路联系起来，再加上教师在讲授的时候没有有效引导，从而导致这样的错误出现。
教学建议： 教师在引导学生认真审题的同时，也要引导学生交流和反馈解题的思路，使学生明确48-7+12=53（人）这个算式中，4第一步48-7就表示转走7人以后班级的人数，再加上12表示转来后现在学生的人数。对比分式48-7=41、41+12=53（人）不难发现，二者的解题思路是一样的，从而告诉学生解题思路相同的算式是相同的方法，激发学生从另外一个角度思考问题，如48+12-7=53，先求出转来后的班级人数，再求转走后的班级总人数。 错例2 题目描述： 校园里有22盆菊花，月季花比菊花多13盆，两种花一共有多少盆？ 典型错例： 错因分析： 通过学生的做题，可以分析出造成学生错误的原因大致有两个：首先是学生审题不够仔细，对于问题没有认真分析，想当然的拿两个已知的数字22和13相加；其次学生对其中的数量关系不够明确，没有认真分析其中的两个已知条件以及要求的问题，特别是“月季花比菊花多13盆”这个中间条件分析得不够透彻，以至于不知其所以然。
在教学过程中，教师要引导学生反复阅读题目，认真分析其中的数量关系，知道要想求“两种花一共有多少盆”这一问题，必须知道月季花和菊花各多少盆，从而顺着问题去找。学生进而从已知的条件中知道菊花有22盆，但月季花需要借助“月季花比菊花多13盆”这一中间条件去求，从而知道月季花可以用“22+13”这一式子表示，找到了两个必须的条件，“两种花一共多少盆”学生就可以列式22+13+22=57（盆）。因此在此类知识上，引导学生对于已知条件和数量关系的分析是今后教师教学的重心。 错例3 题目描述： 小红：我今年6岁。妈妈：我的年龄是小红的6倍。妈妈比小红大几岁？ 典型错例： 错因分析： 学生出现此类错误的原因主要是审题不够仔细，对于问题没有斟酌就开始下笔，以至于答非所问。另外一个原因就是，学生对已知条件的分析还不到位，对于“我的年龄是小红的4倍”这一中间条件理解还不是很透彻。

不等式易错题分析 一、解一元二次不等式的易错题 （一）、随意消项致误 例题1：解不等式; 22(44)(43)0x x x x -+-+≥ 错解：原不等式可化为：2(2)(1)(3)0x x x ---≥ 解得2(2)0,(1)(3)0x x x -≥∴--≥ 所以31x x ≥≤或 原不等式的解集为：{}|31x x x ≥≤或 剖析：错误是由于随意消项造成的，事实上，当2(2)0x -=时，原不等式亦成立 正解：原不等式可化为：20x -≠且(1)(3)0(2)0x x x --≥-=或 解得31x x ≥≤或或x=2 所以原不等式的解集为：{}31x x ≥≤x|或或x=2 （二）、函数不清致误 例题2：已知函数22(45)4(1)3y m m x m x =+-+-+的图像都在x 轴的下方，求实数m 的取值范围。 错解：，依题意，对,0x R y ∈>恒成立，于是函数的图像开口方向向上，且图 像与x 轴无交点。故[]2224504(1)43(45)0 m m m m m ?+->???=--+-
正解：当2450m m +-≠时，同上述解答有119m <<， 若2450m m +-=时，则m=1或m=5 若m=1，,则已知函数化为3y =，则对,0x R y ∈>恒成立； 若m=5，则已知函数化为243y x =+，对,0x R y ∈>不恒成立，故此情形舍去。 所以m 的取值范围为119m ≤< （三）、漏端点致误 例题3：已知集合{}{}2|20,|3A x x x B x a a =--≤=<+，且A B φ=，则实数a 的取值范围是____________ 错解：{}{}2|20|12A x x x x x =--≤=-≤≤ 若使A B φ=，需满足231a a >+<-或，解得24a a ><-或，所以实数a 的取值范围是24a a ><-或。 剖析：上面的解法错误原因在于忽视了集合{}|12A x x =-≤≤的两个端点值-1和2，其实当2a =时{}|25B x x =<<，满足A B φ=；当31a +=-时，即4a =-时也满足A B φ=。 正解：{}{}2|20|12A x x x x x =--≤=-≤≤若使A B φ=，需满足231a a ≥+≤-或，解得24a a ≥≤-或，所以实数a 的取值范围是 24a a ≥≤-或。 (四)、条件非充要致误 例题4：若方程2(2)50x m m +-+-=的两根均大于2，求实数m 的取值范围。 错解：设两根为12,x x ，则有题意可得：1212044x x x x ?≥??+>??>?2(2)(5)02454m m m m ?---≥??->??->?
