Hi , TigerMom,

What puzzles you is actually a puzzle for many parents in China.

答案

Hi , TigerMom,

What puzzles you is netually a puzzle for many parents in China .  In my opinion , what you think and what you do are not suitable.

Although high grades are important in assessing students and for their future university admission, development in wisdom ,emotion, health,and life attitude should never be ignored. There are many examples around us . Some top students in school have turned out not to be as sueeessfus in society as they are expccted . The reason is often that the pressure from their parents allows them almost no time for other activities . Besider , punishment is by no means a wise choiee to

help them grow up mentally and physieally.

So I suggest that you take your friends ’ advice. More importantly, let her live like a lovely girl , let her have more friends and soeial activities ,and let her make mistakes of her own as the teenagers often do.

单项选择题 A3/A4型题
实验题

(1)在“验证力的平行四边形定则”的实验情况如图甲所示,其中A为固定橡皮筋的图钉,O为橡皮筋与细绳的结点,OB和OC为细绳。图乙是在白纸上根据实验结果画出的图。

①图乙中的F与F′两力中,方向一定沿AO方向的是____________________

②本实验采用的科学方法是(  )

A.理想实验法

B.等效替代法

C.控制变量法

D.建立物理模型法

(2)在做“研究匀变速直线运动”的实验时,某同学得到一条用打点计时器打下的纸带如图所示,并在其上取A、 B、 C、 D、 E、F、G等7个计数点,每相邻两个计数点间还有4个点,图中没有画出,打点计时器接周期为T="0.02" s的交流电源.他经过测量并计算得到打点计时器在打B、 C、 D、 E、F各点时物体的瞬时速度如下表:

①计算的公式为=         

②根据(1)中得到的数据,以A点对应的时刻为t=0,作出v-t图象,并求物体的加速度

a=    m/s2 ;

(3)某同学设计了如图甲所示的装置来探究加速度与力的关系。打点计时器固定在一端带有定滑轮的长木板上,细绳的两端分别与带有纸带小车和矿泉水瓶连接。

①该小组在实验操作中,在保持小车的质量不变的情况下,向矿泉水瓶中逐渐加水,研究小车加速度与小车受力的关系。这种实验研究方法叫做             

②利用多次测量的数据,画出了如图丙所示的a-F关系图线。

分析发现图线在水平轴上有明显的截距 (OA不为零),这是因为:_     ___                _____。
