巴蜀中学2021届高考适应性月考卷(一)—(十)试卷及答案

与平面 A1B1C1D1 的所有交线均与直线 PQ 平行，根据平行的传递性，可得所有交线也平行；
对于 C 选项，设正方体棱长为 1，PB = DQ = a ∈ (0，1) ，则 AP = AQ = a2 + 1 ，PQ = 2 ，
则

巴蜀中学2021届高考适应性月考卷（五）物理一、选择题：本大题共10小题。

在每小题给出的四个选项中，第1～7题只有一项符合题目要求，第8～10题有多项符合题目要求。

1．如图所示，物体（视为质点）在t＝0时刻开始以初速度v0做匀减速直线运动，直至停下。

以t＝0时的位置为坐标原点，沿运动方向建立x轴，则物体的x-t图象可能为A．B．C．D．2．取无限远处电势为零，某种电场中x轴上各点的电势分布如图甲所示，则x轴是图乙中的A．图①：x轴是等量异种（左正右负）电荷的连线B．图②：x轴是等量正电荷的连线C．图③：x轴是等量异种（下正上负）电荷连线段的中垂线D．图④：x轴是等量正电荷连线段的中垂线3．如图所示，质量为m1＝2 kg的滑块放置在质量为m2＝5 kg的木板上，木板处于水平地面上，木板与水平地面间的动摩擦因数μ2＝0.1。

现用F＝21 N的水平力向右拉木板，测得木板的加速度a2＝2 m/s2。

取g＝10 m/s2，设最大静摩擦力等于滑动摩擦力。

则滑块与木板间的动摩擦因数μ1可能为A．0.05 B．0.10 C．0.15 D．0.254．将行星视为质量均匀的标准球体，地球与某行星的密度之比为2︰1，则地球的近地卫星的周期与该行星的近地卫星的周期之比为A．2︰1 B C．D．1︰25．如图，传送带倾角θ＝37°，以恒定的速率v0＝10 m/s逆时针匀速转动。

AB两端距离为L ＝16 m，在A端无初速度放上质量m＝1 kg的滑块，滑块与传送带间的动摩擦因数μ＝0.5，最大静摩擦力等于滑动摩擦力。

取g＝10 m/s2，对滑块从A端运动到B端的过程，下列说法正确的是（cos37°＝0.8）A．滑块先做匀加速运动，再做匀速运动B．滑块先做匀加速运动，再做匀减速运动C．滑块的机械能减少了24 J D．滑块的机械能减少了16 J6．如图所示电路中，R1＝R2＝R3＝6 Ω，电容C＝1 μF；电源电动势E＝6 V，内阻r＝3 Ω。

Could we incorporate community service activities into our experience?Community service not only allows us to learn about the world beyond the classroom first hand，but also offers us a unique opportunity to develop essential skills like teamwork，leadership，and communication through interacting with different people in diverse settings．We could engage in activities that address issues such as environmental conservation，children’s education，and healthcare．As for the assignment，I suggest that we submit a written report on our experiences and reflections or create an engaging video diary that captures our journey．I hope my suggestions will be taken into consideration．Thank you for offering this remarkable opportunity!—Li Hua英语参考答案·第1页（共9页）第二节（满分25分）【参考范文】It was then that my moment of courage arrived，inspiring me to act．With trembling hands and a pounding heart，I rose to my feet and recounted the story of the boy in my class．I described the cruel teasing he endured and our unawareness of his pain．Overwhelmed by emotion，I urged my classmates to put an end to the cruelty．As I finished speaking，a deafening silence enveloped the room．After what seemed like an eternity，soft clapping started in the front of the room，spreading throughout the entire audience．I knew I had touched something deep within us all．Later that day，the boy I had been talking about came up to me privately．With lowered eyes and flushed cheeks，he expressed his gratitude in a quivering voice．I gave him a bear hug，offering my delayed but heartfelt apologies．From that day on，I noticed that people began to treat him a lot better．The teasing stopped，and people greeted him in the halls with a friendly，“Hi!”It was those little，everyday things that I noticed．And I reckoned it was the speaker’s words of wisdom as well as our courage to change that made a huge difference to the boy and us as well．【解析】第二部分阅读第一节A【语篇导读】本篇为应用文。
