2012年上海市长宁区中考物理一模试卷

2012年上海市长宁区中考物理一模试卷参考答案与试题解析满分90分一、选择题(共16分)1.(2分)(2013•闵行区一模)下列各物理量中,可以用来鉴别物质的是()A.密度 B.体积 C.质量 D.重力【考点】密度PH113;重力PH215;质量PH112【难易度】容易题【分析】本题考查的是物质的特性:(1)不同的物质密度一般是不同的,密度是物质的一种特性,可根据密度的大小鉴别物质;(2)任何物质的体积是任意的,体积不是物质的一种特性,不能根据体积的大小鉴别物质;(3)任何物质的质量是任意的,质量不是物质的一种特性,不能根据质量的大小鉴别物质;(4)任何物质的重力是任意的,重力不是物质的一种特性,不能根据重力的大小鉴别物质;所以本题答案选择A.【解答】A.【点评】解决本题需要我们掌握密度用来鉴别物质的原理,密度是物质的一种基本属性,测量物体的密度实验是中考常见题型,考生在日常学习和实验中要注意积累总结物质的相关性质。

2.(2分)(2011•长宁区一模)一本九年级物理第一学期教科书平放在水平桌面上,它对桌面的压强约为()A.3帕B.30帕C.300帕D.3000帕【考点】重力PH215;压强PH232【难易度】容易题【分析】本题考查的是生活中常见物理量的估测:已知物理课本的质量约为150g,长度约25cm,宽度约20cm,课本质量m=150g=0.15kg,重力G=mg=0.15kg×10N/kg=1.5N,因为课本在水平桌面上,所以桌面受压力F=G=1.5N,与桌面的接触面积s=25cm×20cm=500cm2=0.05m2,桌面受压强:p=F/s=1.5N÷0.05m2=30Pa.所以本题答案选择B.【解答】B.【点评】解决本题需要我们掌握重力和压强的相关计算,学会合理的估测生活中常见的一些物理量,结合物理知识和实际情况对物理量的数值、数量级进行相应的估测。

3.(2分)(2011•长宁区一模)下列情况中,属于串联的是()A.教室里的各盏电灯 B.马路上的各盏电灯C.手电筒中的干电池组 D.家里的电脑和电冰箱【考点】串联电路、并联电路PH316【难易度】容易题【分析】本题考查的是生活中利用串联电路的实例:(1)教室里的各盏电灯之间独立工作,互不影响,所以它们之间属于并联电路;(2)由(1)可知马路上的各盏电灯和教室里的各盏电灯之间相似,属于并联电路;(3)因为干电池串联总电压等于各干电池的电压之和,所以手电筒中的干电池组是串联;(4)家里的电脑和电冰箱之间独立工作,互不影响,所以它们之间属于并联电路;所以本题答案选择C.【解答】C.【点评】解决本题需要我们掌握生活中常见的串并联电路及两者之间的区别,家庭电路中不同用电器之间是并联连接,彼此之间独立工作,互不影响,而控制用电器的开关则与用电器串联连接,以达到控制电路的目的。

2012年上海初三英语一模--回答问题

长宁区初三英语第一学期期末质量抽查试卷D.Answer the questions(根据短文内容回答问题):(12分)Exam time is the most stressful(压力重的) period of the year。

You have worked all school term on your classes and now it’s the time to prove what you have learned. With so much at stake (处于成败关头), it is easy to get stressed about your exams。

However, with the right amount of hard work and focus you can pass your tests with ease。

When I was in school, I used to get very stressed over my exams。

So did my friends。

Some people stopped eating and others ate too much! Some gave up and others burned themselves out!The most important thing to remember when studying is not to feel frightened! Take the middle path —— stay calm, eat healthy and get a rest。

Pushing yourself too hard is just as dangerous as not studying enough. A tired, overworked brain is just as useless as a lazy, empty one!So, what should you do ?Arrange a time each day for study and a time for relaxation 。
