Ming.Do you have______basketball.﹣Yes,it's over there,behind______door.()A.a,a B.the,the C.a,the D.the,a【分析】﹣嘿,李明,你有一个篮球吗?﹣是的,在那边,在门后边.【解答】答案:C根据题意"﹣嘿,李明,你有一个篮球吗?﹣是的,在那边,在门后边.",可知第一个空表示泛指,泛指一个篮球,basketball发音以辅音音素开头,用a,故排除B D;第二个空是介词短语表达地点,用定冠词the,其结构是介词+the+名词,故选C.【点评】熟悉冠词的基本用法,结合题意,给出答案.27.(1分)﹣Our classroom is so clean.Who's cleaned it,Li Fei?﹣Sorry,I don't know.I think______did it before class.()A.somebody B.nobody C.everybody D.anybody【分析】﹣我们的教室如此干净.谁打扫的,李飞?﹣对不起,我不知道.我认为有人在课前打扫的.【解答】答案:A根据题干"did it before class在课前打扫的",可知是有人打扫,结合选项,A.某人B.没人C.每个人D.任何人,故选A.【点评】熟悉物不定词的基本用法,结合题意,给出答案.28.(1分)﹣What's your prediction about the______of our school basketball match next week.﹣I'm sure Class 8 will be the winner.()A.teammate B.result C.information D.player【分析】﹣你对我们学校下周篮球赛的结果有什么预测?﹣我相信8班肯定会赢.【解答】答案:Bteammate队友;result结果;information信息;player运动员;根据答语I'm sure Class 8will be the winner我相信8班肯定会赢,可知上句应是问对篮球比赛结果的预测,所以应该用名词result结果.故选B【点评】细读所提供的选项,认真分析它们的不同含义,然后在理解句意把握语境的基础上,选择正确的答案.29.(1分)﹣I haven't find the book report of Journey to the West.It's so difficult.﹣You should hurry up.The report is due______three days.()A.in B.for C.on D.at【分析】﹣﹣我还没有找到《西游记》的读书报告,太难了.﹣﹣你应该赶快,报告三天后到期.【解答】答案:A.结合语境可以推断这句话表达的意思是"﹣﹣我还没有找到《西游记》的读书报告,太难了.﹣﹣你应该赶快,报告三天后到期.",所以设空处的介词短语表达的意思是"三天后",应该用in+时间段,故选A【点评】英语介词的一个特点是一词多义,并且介词间语义交叉现象很多,习惯用法也很多,有时很难从词义上区分开来.故学习中要注意不断总结,熟记一些介词和动词的固定搭配用法及习惯用法,是完成此类问题的捷径.30.(1分)﹣Do you think we should share our problems with our parents?﹣Sure!______we talk to them,we will feel worse.()A.If.B.Although.C.Because.D.Unless【分析】﹣﹣你认为我们应该让家长分担我们的问题吗?﹣﹣当然,如果我们不跟家长谈,我们会感到更加糟糕.【解答】答案:D.首先明确选项中每个单词或短语的意思,A:如果;B:虽然;C:因为;D:除非;本题考查的是从属连词的辨析.根据语境推测句意是"当然,如果我们不跟家长谈,我们会感到更加糟糕."从句意来看,这里需要一个表假设的连词,说明后句是表假设的条件状语从句,结合选项,unless可以引导一个表假设的条件状语从句,意为"除非",相当于if not.故选D.【点评】本题主要考查连词的用法,连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词.是做好此类题型的关键.31.(1分)﹣Which country has the______population in the world.﹣China.It's a little______than that of India.()A.most,most B.biggest,biggerC.more,most D.bigger,bigger【分析】﹣世界上人口最多的是哪个国家?﹣中国.它比印度的人口多一点.【解答】答案:B根据答语China及常识可知上句应是问世界上人口最多的是哪个国家,应用最高级形式;先排除CD;修饰人口population的数量大,人口多应该用big或large;结合选项,所以此处应该用big的最高级biggest;根据关键词than,可知第二空应该用比较级,此句是中国和印度的人口作比较,应是指中国的人口比印度要多一点,a little修饰比较级,所以此处应用big的比较级bigger.综合以上分析,故选B【点评】判断形容词或副词的比较级和最高级,主要是结合语境及看几者之间的比较.两者之间用比较级,三者或三者以上比较用做高级形式.32.(1分)﹣Are we going to have a sports meeting on Friday Li Ping?﹣No,it will be______till next week because of the bad weather.()A.put out B.put on C.put away D.put off【分析】﹣﹣这个星期五我们开运动会吗,李平?﹣﹣不,由于糟糕的天气它被推迟到下一周.【解答】答案:D.Put off意为"推迟";put away意为"将某物放起来";put on意为"穿上,戴上,上映";put out意为"扑灭";根据because of the bad weather,可知由于糟糕的天气它被推迟到下一周.故选D.【点评】短语动词是由动词加介词、副词或其他词构成的词组,其作用和动词差不多.有些短语动词相当于及物动词,有些则相当于不及物动词.33.(1分)﹣______this past three years,which teachers will you miss most?﹣Mr Jiang.He's helped me a lot.()A.Looking back at B.Looking forC.Looking through D.Looking after【分析】﹣回首这过去的三年中,你会最想念哪位教师?﹣江老师,他帮了我很多忙.【解答】答案:Alook back at回顾;look for寻找;look through浏览;look after照看;根据关键部分this past three

25.A二、单项选择(共15小题;每小题1分,满分15分)从A、B、C、D四个选项中,选出可以填入空白处的最佳选项.26.(1分)【考点】52:不定冠词(a,an).【分析】﹣嘿,李明,你有一个篮球吗?﹣是的,在那边,在门后边.【解答】答案:C根据题意"﹣嘿,李明,你有一个篮球吗?﹣是的,在那边,在门后边.",可知第一个空表示泛指,泛指一个篮球,basketball发音以辅音音素开头,用a,故排除B D;第二个空是介词短语表达地点,用定冠词the,其结构是介词+the+名词,故选C.【点评】熟悉冠词的基本用法,结合题意,给出答案.27.(1分)【考点】65:不定代词.【分析】﹣我们的教室如此干净.谁打扫的,李飞?﹣对不起,我不知道.我认为有人在课前打扫的.【解答】答案:A根据题干"did it before class在课前打扫的",可知是有人打扫,结合选项,A.某人B.没人C.每个人D.任何人,故选A.【点评】熟悉物不定词的基本用法,结合题意,给出答案.28.(1分)【考点】48:名词的词义辨析.【分析】﹣你对我们学校下周篮球赛的结果有什么预测?﹣我相信8班肯定会赢.【解答】答案:Bteammate队友;result结果;information信息;player运动员;根据答语I'm sure Class 8will be the winner我相信8班肯定会赢,可知上句应是问对篮球比赛结果的预测,所以应该用名词result结果.故选B【点评】细读所提供的选项,认真分析它们的不同含义,然后在理解句意把握语境的基础上,选择正确的答案.29.(1分)【考点】7B:常用介词的辨析.【分析】﹣﹣我还没有找到《西游记》的读书报告,太难了.﹣﹣你应该赶快,报告三天后到期.【解答】答案:A.结合语境可以推断这句话表达的意思是"﹣﹣我还没有找到《西游记》的读书报告,太难了.﹣﹣你应该赶快,报告三天后到期.",所以设空处的介词短语表达的意思是"三天后",应该用in+时间段,故选A【点评】英语介词的一个特点是一词多义,并且介词间语义交叉现象很多,习惯用法也很多,有时很难从词义上区分开来.故学习中要注意不断总结,熟记一些介词和动词的固定搭配用法及习惯用法,是完成此类问题的捷径.30.(1分)【考点】C3:连词辨析.【分析】﹣﹣你认为我们应该让家长分担我们的问题吗?﹣﹣当然,如果我们不跟家长谈,我们会感到更加糟糕.【解答】答案:D.首先明确选项中每个单词或短语的意思,A:如果;B:虽然;C:因为;D:除非;本题考查的是从属连词的辨析.根据语境推测句意是"当然,如果我们不跟家长谈,我们会感到更加糟糕."从句意来看,这里需要一个表假设的连词,说明后句是表假设的条件状语从句,结合选项,unless可以引导一个表假设的条件状语从句,意为"除非",相当于if not.故选D.【点评】本题主要考查连词的用法,连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词.是做好此类题型的关键.31.(1分)【考点】81:形容词的比较级和最高级.【分析】﹣世界上人口最多的是哪个国家?﹣中国.它比印度的人口多一点.【解答】答案:B根据答语China及常识可知上句应是问世界上人口最多的是哪个国家,应用最高级形式;先排除CD;修饰人口population的数量大,人口多应该用big或large;结合选项,所以此处应该用big的最高级biggest;根据关键词than,可知第二空应该用比较级,此句是中国和印度的人口作比较,应是指中国的人口比印度要多一点,a little修饰比较级,所以此处应用big的比较级bigger.综合以上分析,故选B【点评】判断形容词或副词的比较级和最高级,主要是结合语境及看几者之间的比较.两者之间用比较级,三者或三者以上比较用做高级形式.32.(1分)【考点】E1:动词短语.【分析】﹣﹣这个星期五我们开运动会吗,李平?﹣﹣不,由于糟糕的天气它被推迟到下一周.【解答】答案:D.Put off意为"推迟";put away意为"将某物放起来";put on意为"穿上,戴上,上映";put out 意为"扑灭";根据because of the bad weather,可知由于糟糕的天气它被推迟到下一周.故选D.【点评】短语动词是由动词加介词、副词或其他词构成的词组,其作用和动词差不多.有些短语动词相当于及物动词,有些则相当于不及物动词.33.(1分)【考点】E7:动名词短语.【分析】﹣回首这过去的三年中,你会最想念哪位教师?﹣江老师,他帮了我很多忙.【解答】答案:Alook back at回顾;look for寻找;look

分析:根据倒数的定义直接解答即可.解答:解:∵(﹣)×(﹣2)=1,∴﹣的倒数是﹣2.点评:本题考查倒数的基本概念,即若两个数的乘积是1,我们就称这两个数互为倒数.属于基础题.2、(2017•随州)分解因式:8a2﹣2=2(2a+1)(2a﹣1).考点:提公因式法与公式法的综合运用。
分析:先提取公因式2,再根据平方差公式进行二次分解即可求得答案.解答:解:8a2﹣2,=2(4a2﹣1),=2(2a+1)(2a﹣1).故答案为:2(2a+1)(2a﹣1).点评:本题考查了提公因式法,公式法分解因式.注意分解要彻底.3、(2017•随州)要使式子有意义,则a的取值范围为a≥﹣2且a≠0.考点:二次根式有意义的条件。
专题:计算题。
分析:根据二次根式的性质和分式的意义,被开方数大于或等于0,分母不等于0,可以求出x的范围.解答:解:根据题意得:a+2≥0且a≠0,解得:a≥﹣2且a≠0.故答案为:a≥﹣2且a≠0.点评:本题考查的知识点为:分式有意义,分母不为0;二次根式的被开方数是非负数.4、(2017•随州)如图:点A在双曲线上,AB丄x轴于B,且△AOB的面积S△AOB=2,则k=﹣4.考点:反比例函数系数k的几何意义。
专题:探究型。
分析:先根据反比例函数图象所在的象限判断出k的符号,再根据S△AOB=2求出k的值即可.解答:解:∵反比例函数的图象在二、四象限,∴k<0,∵S△AOB=2,∴|k|=4,∴k=﹣4.故答案为:﹣4.点评:本题考查的是反比例系数k的几何意义,即在反比例函数的图象上任意一点象坐标轴作垂线,这一点和垂足以及坐标原点所构成的三角形的面积是,且保持不变.5、(2017•鄂州)如图:矩形ABCD的对角线AC=10,BC=8,则图中五个小矩形的周长之和为28.考点:平移的性质。
