上海自主招生试题及答案

上海自主招生试题及答案自主招生是中国普通高校招生渠道之一,也是一种选拔高中生的重要方式。
上海自主招生试题涵盖了多学科,旨在全面评估学生的综合素质。
本文将为您介绍上海自主招生试题的示例以及相应的答案。
1. 语文试题阅读下面的短文,然后根据短文内容回答问题。
【短文】人们常说“树有生命”,到底是怎样的呢?从春天到秋天,树会在它的枝叶上生出花朵、绿叶、果实等。
砍倒一棵树,它还能给人们送来燃料、建筑材料。
人们在束蓬、华表上雕刻图案,画门窗花样,这些都离不开树来;人们用树皮造纸,还用树根造药,这些也是人们利用树木创造出来的。
所以人们说:“树有生命是真理”,是树给人们带来方便、实用的东西而说的。

But usually people would accept tame(温顺的) and loyal(忠诚的) animals as pets rather than dangerous ones such as a lion,a tiger or a snake.People love pets and take good care of them. The owners usually regard pets as good friends and some even consider them as members of the family.

We often hear that a pet dog saved the owner's life or traveled thousands of miles to return home. Such stories often make pets more lovely.Some pets can also be trained to help people with some special work. For example, trained dogs can help the blind to walk and trained dogs and pigs can even help police to find where drugs are easily.But pets are sometimes trouble-makers. Some pets like dogs or snakes may hurt people without any warning. Some people may become ill after being hurt because of the virus carried by the pets. If they are not taken good care of, they will become very dirty and easily get ill. So pets are helpful to us but keeping pets is not an easy job.51.

1.如图,在P-V图像中,气体做一个完整的循环,轨迹是一个圆心在(2,2),半径为1的圆。
(1)求在这个循环中的最大温度是哪个点(2)在这个循环中对外做的功是多少2、如图所示,半径为R的空心圆环固定在滑块上,滑块放置在光滑水平地面上,滑块与圆环的总质量为M,质量为m的小球(看成质点)可在环内作无摩擦运动。
开始时小球位于圆环最高点,环与小球均静止。
在微小扰动下小球沿环下滑。
1)试求小球相对地面的轨迹方程2)试用物理方法求小球轨迹(相对地面)在图中A、B两处的曲率半径。
3、我们设计了一个理想的实验:设有两个黑体I和II,其平衡温度分别为T1和T2,且T1>T2,C为连接两个黑体场的真空圆筒,筒中有两个可无摩擦滑动的平面活塞A和B,圆筒的内壁和活塞A,B的两个平面都是理想的反射面,初始时刻活塞A和B的平面分别紧贴黑体I和II的位置1和2,如图所示。
现作如下操作:先将B移出筒C,让黑体II的辐射能充满C,再将B移回到位置2,并把A移出筒C,然后推动活塞B,当B移到位置1时,筒C中的辐射能全部被黑体I吸收,此时,筒中又充满了黑体II的辐射能。
把活塞A和B轮流移入和移出,重复上述过程,黑体II的辐射能不断地被黑体I吸收,从而使黑体I温度不断上升,黑体II的温度不断下降。
1)证明:使活塞在筒中移动时要消耗功;2)活塞在筒中移动时所做的功实际上是克服了“光压”,即光照射在物体表面会产生压强作用。
现重复上述实验使得q的热量从黑体II传到了黑体I,问活塞克服光压所做的功至少是多少?(假设黑体I,II都非常大,以至于这个过程种T1和T2可视为恒定值)4、在空间A点有电量为5Q的固定点电荷,在B点有电量为12Q的固定点电荷,A点和B点相距13a,空间另一C点与A点和B点分别相距5a和12a。
1)以C点为球心,以r=a为半径作一球,试求在该球区域内,静电场电场强度E的平均值的大小(表达式为:)式中E i是在体积元△V i处的电场强度。

10.若一个圆锥的侧面展开图是半径为18cm,圆心角为240°的扇形,则这个圆锥的底面半径长是9cm。
11.如图,已知在矩形ABCD中,点E在边BC上,BE=2CE,将矩形沿着过点E的直线翻折后,点C、D、N处,B在同一直线上,分别落在M、F与BE交于点G.设AB=√3,那么△xxx的周长为4+4√3.12.如图,已知点x1,x2,…,xx均在直线x=x−1上,点x1,x2,…,xx均在双曲线x=−x上,x1x1⊥x并且满足:x1x2⊥x轴,x2x2⊥x轴,…,xx−1xx⊥x轴,xxxx⊥x轴,且x1x2=x2x3=…=xx−1xx,则n的最小值为2.1.由题意可知,点B在x轴负半轴,点A在x轴正半轴,且AB垂直于x轴,因此AB的斜率为0,即AB为x轴,所以B的纵坐标为0.又因为B在x轴负半轴,所以其横坐标为负数,设为-a。
