  • 河北省2016年中考文综(历史部分)真题试题(含答案)

    第二次世界大战终于落下了帷幕,但人们所希望的真正和平并未降临。美国、苏联这对战时的盟友很快变成了“冷战“的对手。”“冷战”为什么会爆发呢?史学家们从以下四个不同角度进行了分析:[角度一]美国当时拥有最强大的经济与军事实力,确立了称霸世界的全球战略,日益把苏联看作其称霸全球的主要障碍,企图遏制苏联。[角度二] 苏联为反法西斯战争胜利做出了重大贡献,国际威望大大提高,并且军事力量大大加强,能与美国抗衡。战后,苏联把确保东西部边界安全作为国家的首要利益,在自己的周边建立“安全带”,努力扩大自己在世界上的影响,推行大国沙文主义(即征服和奴役其他民族的思想和主张。)

  • 湖北省潜江市、天门市、仙桃市、江汉油田2015年中考语文真题试题(含答案)

    中国邮政日前宣布开放全国5000个自提网点,任何一家快递公司发货,均可享受此服务。自提网点包括现有邮政自有网点和“无人值守”的智能快递柜。看似简单的自提系统开放,背后却是智能快递的大市场。企业、专家、主管部门等负责人均认为,智能快递已成为当前政府驱动快递满足消费和商业需求的重要手段。快递员将快递包裹送到置于小区的智能快递柜中,给收件人发送取件短信。收件人经过手机查询——输入密码——开门取件三个步骤,便可将一个快递包裹从智能快递柜中取出,抱回家去。这种方式越来越受到居民和快递员欢迎。中国快递协会常务副会长李惠德说,目前出现的一些智能快递柜,代表着未来中国快递业的发展方向——智能快递,即通过引入信息化、大数据等现代化手段,融合预测等方式,以更加便捷的智能设施(如智能快递柜)和手段满足高密度、高成本、高人力的现代快递工作,通过建设社区的“智能快递站”为消费者服务。

    The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分,只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition
