Research shows that people often come up with more solutions to problems after they’ve taken a break.So next time you’re stuck with homework,stop for a moment and see where your daydreams take you.41.Which writing skill is used in paragraph1?A.Giving an example.B.Raising a question.C.Listing numbers.D.Comparing facts.42.Daydreaming can make people_________.A.fly around B.walk slowly C.think freely D.beabsent-minded43.Guo Qiang first suggests_________.A.escaping from the hard time B.looking for new worldsC.finding time to imagine D.focusing on success44.What is mentioned in paragraph4?A.The steps to daydream.B.The things to daydream of.C.The reasons for daydreaming.D.The meanings of daydreaming. 45.Daydreaming is talked about_________. A.to remind people to have a mind break B.to suggest living at the momentC.to find solutions to homework problems D.to show a science research result四、多句选词填空五、短文综合填空六、材料作文61.你的英语老师布置了一项体验式作业,希望你和家人假期时去一次公园,然后写一篇英文短文,向同学们介绍公园离你家有多远,能在公园内体验的活动项目及公园周边生活设施。

2023年湖北省武汉市中考数学试卷及答案解析(word版)

2023年湖北省武汉市中考数学试卷及答案解析(word版)考试时间:2023年6月考试科目:数学考试地点:湖北省武汉市一、选择题(共30题,每题2分,共60分)1. 在三角形ABC中,已知∠A=60°,AB=5cm,AC=8cm,则BC的长度是多少?A. 5 cmB. 8 cmC. 11 cmD. 13 cm2. 若一元二次方程ax^2+bx+c=0(a≠0)的两个根为x1和x2, 则x1 + x2 的值是多少?A. aB. bC. cD. -b/a...二、填空题(共20题,每题2分,共40分)1. 设直线k的斜率为3,且过点(-2, 4),则直线k的方程是__________。

2. 若两个互为倒数的有理数和为0,则这两个数分别是__________和__________。

...三、解答题(共2题,每题20分,共40分)1. 已知函数y=2x^2-5x+3,求其对称轴方程和顶点坐标。

解答:对称轴方程的一般形式为x=h,其中h为对称轴的横坐标。

根据对称性,对称轴上任意一点(h,y)的函数值与对称轴上与其关于顶点对称的点(h,y')的函数值相等。

所以,有2h-5h+3=y-y',整理得到3h=y+y'-3。

由于顶点在对称轴上,所以顶点的横坐标与对称轴的横坐标相等,即h=x。

代入方程3h=y+y'-3中,得到3x=2x^2-5x+3。

解方程2x^2-8x+3=0,得到x=1或x=1.5。

将x=1和x=1.5代入函数y=2x^2-5x+3,求得顶点坐标分别为(1, 0)和(1.5, -0.75)。

所以,对称轴方程为x=1,顶点坐标分别为(1, 0)和(1.5, -0.75)。

2. 两条非平行直线分别是直线k1和直线k2,已知直线k1的斜率为2,过直线k1的一点(3,-2),直线k2经过(1, 4)且与直线k1垂直,求直线k2的斜率和方程。

解答:由直线k1的斜率为2,过直线k1的一点(3,-2),可得直线k1的方程为y-(-2)=2(x-3),整理得 y=2x-8。

(10分)文创产品如何破解同质化难题①文创产品指以文化为主题或基本元素,在设计、加工、营销等环节融入创新意识,兼具文化内涵与创新属性的产品。

小到一张贴纸、一对耳环,大到一个电视节目、一处旅游景点,都可以被赋予特定的文化内涵,打造为文创产品。

②优秀的文创产品不仅可以表达文化、传承文化,更能推动文化产业发展,助力经济增长,中央广播电视台制作的文创精品《国家宝藏》节目,别出心裁地将有代表性的中国文物与电视舞台剧的艺术表现形式结合起来,讲述中国文物宝藏的前世今生。

节目播出后,故宫博物院等多家国家级博物馆的参观人数大幅增加,“为一座博物馆赴一座城”成为旅游打卡的新趋势。

③优秀的文创产品带来了消费热潮,文创产品的同质化问题也随之出现。

某地青砖灰瓦的传统建筑成为了旅游热点,不久各地就都建起了“仿古主题小镇”——满街青砖灰瓦,哪怕完全不符合当地的历史建筑形态。

一个景区以本地景观为造型的文创雪糕上热搜了,其他景区便亦步亦趋,群起售卖类似的文创雪糕——造型虽然有所不同,吃到嘴里都是一样的甜腻。

(10 分)“信用”的现代意义①诚实守信是中华民族的传统美德。

“人而无信,不知其可也”“自古皆有死,民无信不立”“言必信,行必果”等名句,都强调了“信”的意义与价值,而信用就是从这一传统美德中发展而来的。

②信用是什么?信用是因履行承诺而取得的信任长时间累积的结果,是我们过去履行承诺的正面记录,还是人人可以尝试的自我管理的行为模式。

信用本质上是社会交往关系的产物,社会个体和群体为了生存和发展必须在社会交往中建立一种信用关系。

③信用对社会发展至关重要,直接关乎能否形成良好的社会信任结构,而良好的社会信任结构是一个社会正常运转的基础。

信任与仁爱、友谊、交流一样,是把人与人联系在一起的必不可少的条件,没有人与人之间的普遍信任,社会极易出现裂痕。

只有建立互信,社会方能正常地运行、发展。

④现代社会已形成较为完备的信用体系。

现代社会的信用体系包含四个基本要素,即受信对象、授信主体、信用中介和信用环境。

受信对象通常指的是债务人,即那些接受信用并同意在未来某个时间偿还债务的个体或实体。
