What do you think your college life will be in the first few weeks? Perhaps you will be choosing the classes you want to take.However, if you go to university in Chile there is something extra you must do before you can begin.An important part of starting university in Chile is the mechoneo. The mechoneo is an ancient university tradition there.Students beginning their first year at university are “welcomed” by the older university students. They are taken to a place such as a swimming pool filled with terrible things such as old fruit, vegetables, meat and fish. They have to do games for a whole day, which may include some really revolting things like kissing a dead fish!The “queen mechona” and “king mechona” are chosen that day. This will be based on how well the students do the activities, and many students try hard to be the king or the queen for the year.The older students then take away the younger students' things (their backpacks, money, phones, etc.) and tell them they must go out onto the street and ask people for money. They will need to bring back a certain amount of money (e.g.around 20 dollars per person) in order to be given their things back. This money is then used to have a welcome party at nighttime.During the month of March it is common to see new university students all around the town wearing dirty clothes and covered in paint and mess. But the mechoneo is increasingly a source of debate.Some students see it as an important tradition and a unique experience that can help new arrivals get to know everyone while others find it shameful. There have been campaigns to ban (取缔) it and student organizations in some universities have voted to end the mechoneo completely.【语篇解读】本文语篇类型是说明文，主题语境是校园生活。

2023年人教版高中物理选择性必修第三册第一章学业质量检测试卷及答案
本章学业质量标准检测本卷分第Ⅰ卷(选择题)和第Ⅱ卷(非选择题)两部分。
满分100分，时间75分钟。
第Ⅰ卷(选择题 共40分)一、选择题(共12小题，其中1～8小题只有一个选项符合题目要求，每小题3分，第9～12小题有多个选项符合题目要求，全部选对的得4分，选不全的得2分，有选错或不答的得0分)1．(2023·德州市第一中学高二阶段练习)浙江大学高分子系高超教授的课题组制备出了一种超轻气凝胶，它刷新了目前世界上最轻的固体材料的纪录，弹性和吸油能力令人惊喜，这种被称为“全碳气凝胶”的固态材料密度仅是空气密度的16。
设气凝胶的密度为ρ(单位为kg/m 3)，摩尔质量为M (单位为kg/mol)，阿伏加德罗常数为N A ，则下列说法错误的是( D )A ．a 千克气凝胶所含的分子数N ＝a M N AB ．气凝胶的摩尔体积V mol ＝M ρC ．每个气凝胶分子的体积V 0＝M N A ρD ．每个气凝胶分子的直径d ＝3N A ρM解析： a kg 气凝胶的摩数为n ＝a M ，则1 kg 气凝胶所含有的分子数为N ＝nN A ＝aN A M，A 正确；气凝胶的摩尔体积为V mol ＝M ρ，B 正确；1 mol 气凝胶中包含N A 个分子，故每个气凝胶分子的体积为V 0＝M N A ρ，C 正确；设每个气凝胶分子的直径为d ，则有V 0＝16πd 3，解得d ＝36M πN Aρ，D 错误。
2．(2023·河北张家口宣化一中高二下月考)运用分子动理论的相关知识，判断下列说法正确的是( C )A ．气体分子单位时间内和单位面积器壁碰撞的次数仅与温度有关B ．某气体的摩尔体积为V ，每个分子的体积为V 0，则阿伏加德罗常数可表示为V V 0C ．生产半导体器件时需要在纯净的半导体材料中掺入其他元素，这可以在高温条件下利用分子的扩散来完成D ．水流流速越快，说明水分子的热运动越剧烈，但并非每个水分子运动都剧烈解析： 气体分子单位时间内与单位面积器壁碰撞的次数，与单位体积内的分子数有关，还与分子平均速率有关，故A 错误；由于气体分子的大小相对于分子间的空隙来说很小，故不能用摩尔体积除以分子体积得到阿伏加德罗常数，故B 错误；扩散可以在固体中进行，温度越高，扩散越快，生产半导体器件时需要在纯净的半导体材料中掺入其他元素，这可以在高温条件下利用分子的扩散来完成，C 正确；水流速度反映机械运动情况，不能反映热运动情况，故D 错误。

7．如果函数y ＝3cos(2x ＋φ)的图像关于点⎝⎛⎭⎫4π3，0中心对称，那么|φ|的最小值为( ) A.π6 B.π4 C.π3D.π2解析：选A 由y ＝3cos(2x ＋φ)的图像关于点⎝⎛⎭⎫4π3，0中心对称，知ƒ⎝⎛⎭⎫4π3＝0，即3cos ⎝⎛⎭⎫8π3＋φ＝0， ∴8π3＋φ＝k π＋π2(k ∈Z )，∴φ＝k π－13π6(k ∈Z )， |φ|的最小值为π6.8．同时具有下列性质的函数可以是( )①对任意x ∈R ，f (x ＋π)＝f (x )恒成立；②图像关于直线x ＝π3对称；③在⎣⎡⎦⎤－π6，π3上是增函数．A ．f (x )＝sin ⎝⎛⎭⎫x 2＋π6 B ．f (x )＝sin ⎝⎛⎭⎫2x －π6 C ．f (x )＝cos ⎝⎛⎭⎫2x ＋π3 D ．f (x )＝cos ⎝⎛⎭⎫2x －π6 解析：选B 依题意知，满足条件的函数的周期是π，图像以直线x ＝π3为对称轴，且在⎣⎡⎦⎤－π6，π3上是增函数．对于A 选项，函数周期为4π，因此A 选项不符合；对于C 选项，f ⎝⎛⎭⎫π3＝－1，但该函数在⎣⎡⎦⎤－π6，π3上不是增函数，因此C 选项不符合；对于D 选项，f ⎝⎛⎭⎫π3≠±1，即函数图像不以直线x ＝π3为对称轴，因此D 选项不符合．综上可知，应选B.二、多项选择题(本大题共4小题，每小题5分，共20分) 9．若α是第二象限的角，则下列各式中一定成立的是( )A ．tan α＝－sin αcos αB.1－2sin αcos α＝sin α－cos α C ．cos α＝－1－sin 2α D.1＋2sin αcos α＝sin α＋cos α解析：选BC 由同角三角函数的基本关系式，知tan α＝sin αcos α，故A 错；因为α是第二象限角，所以sin α>0，cos α<0，所以sin α－cos α>0，sin α＋cos α的符号不确定，所以1－2sin αcos α＝(sin α－cos α)2＝sin α－cos α，故B 、C 正确，D 错．10．下列函数中，最小正周期为π的偶函数是( ) A ．y ＝sin ⎝⎛⎭⎫2x ＋π2＋1 B ．y ＝cos ⎝⎛⎭⎫2x ＋π2 C ．f

不满足条件．故选AC. 11．定义：角θ与φ都是任意角，若满足θ＋φ＝π2，则称θ与φ“广义互余”．已知sin(π＋α)＝－14，下列角β中，可能与角α“广义互余”的是( )A ．sin β＝154B ．cos(π＋β)＝14C ．tan β＝15D ．tan β＝155解析：选AC ∵sin(π＋α)＝－sin α＝－14，∴sin α＝14，若α＋β＝π2，则β＝π2－α.A 中sin β＝sin ⎝⎛⎭⎫π2－α＝cos α＝±154，故A 符合条件； B 中，cos(π＋β)＝－cos ⎝⎛⎭⎫π2－α＝－sin α＝－14，故B 不符合条件； C 中，tan β＝15，即sin β＝15cos β，又sin 2β＋cos 2β＝1，故sin β＝±154， 即C 符合条件；D 中，tan β＝155，即sin β＝155cos β，又sin 2β＋cos 2β＝1，故sin β＝±64，故D 不符合条件．12．下列在(0,2π)上的区间能使cos x >sin x 成立的是( ) A.⎝⎛⎭⎫0，π4 B.⎝⎛⎭⎫π4，5π4C.⎝⎛⎭⎫5π4，2π D.⎝⎛⎭⎫π4，π2∪⎝⎛⎭⎫π，5π4 解析：选AC 在同一平面直角坐标系中画出正、余弦函数的图像，在(0,2π)上，当cos x ＝sin x 时，x ＝π4或x ＝5π4，结合图像可知满足cos x >sin x 的是⎝⎛⎭⎫0，π4和⎝⎛⎭⎫5π4，2π，故选AC.三、填空题(本大题共4小题，每小题5分，共20分．把答案填在题中的横线上) 13．已知函数y ＝tan ωx (ω＞0)的图像的相邻两支截直线y ＝1和y ＝2所得的线段长分别为m ，n ，则m ，n 的大小关系是________．解析：∵两条直线所截得的线段长都为y ＝tan ωx (ω＞0)的最小正周期，∴m ＝n ＝πω. 答案：m ＝n 14．arctan33＋arcsin ⎝⎛⎭⎫－12＝________.解析：∵arctan 33＝π6，arcsin ⎝⎛⎭⎫－12＝－π6， ∴arctan 33＋arcsin ⎝⎛⎭⎫－12＝0. 答案：0 15．若函数f (sin x )＝cos 2x ，则f ⎝⎛⎭⎫12的值为________． 解析：令sin x ＝12，得x ＝2k π＋π6或x ＝2k π＋5π6，k ∈Z ，所以f ⎝⎛⎭⎫12＝cos π3＝12. 答案：1216．将函数f (x )＝2sin ⎝⎛⎭⎫ωx －π3(ω＞0)的图像向左平移π3ω个单位得到函数y ＝g (x )的图像．若y ＝g (x )在⎣⎡⎦⎤－π6，π4上为增函数，则ω的最大值为________． 解析：根据题意得g (x )＝2sin ωx ，又y ＝g (x )在⎣⎡⎦⎤－π6，π4上为增函数，所以T 4≥π4，即ω≤2，所以ω的最大值为2.答案：2四、解答题(本大题共4小题，共40分．解答应写出必要的文字说明、证明过程或演算步骤)17．(8分)已知cos ⎝⎛⎭⎫π2＋θ＝12，求cos (3π＋θ)cos θ[cos (π＋θ)－1]＋cos (θ－4π)cos (θ＋2π)cos (3π＋θ)＋cos (－θ)的值．解：因为cos ⎝⎛⎭⎫π2＋θ＝－sin θ，所以sin θ＝－12. 原式＝－cos θcos θ(－cos θ－1)＋cos θcos θ(－cos θ)＋cos θ＝11＋cos θ＋11－cos θ＝21－cos 2θ＝2sin 2θ＝8.18．(10分)函数f (x )＝3sin ⎝⎛⎭⎫2x ＋π6的部分图像如图所示．(1)写出f (x )的最小正周期及图中x 0，y 0的值．(2)求f (x )在区间⎣⎡⎦⎤－π2，－π12上的最大值和最小值．解：(1)f (x )的最小正周期为π，x 0＝7π6，y 0＝3. (2)因为x ∈⎣⎡⎦⎤－π2，－π12，所以2x ＋π6∈⎣⎡⎦⎤－5π6，0， 于是当2x ＋π6＝0，即x ＝－π12时，f (x )取得最大值0； 当2x ＋π6＝－π2，即x ＝－π3时，f (x )取得最小值－3. 19．(10分)设函数f (x )＝3sin ⎝⎛⎭⎫ωx －π3，其中0<ω<3.已知f ⎝⎛⎭⎫π6＝0. (1)求ω；(2)将函数y ＝f (x )的图像上各点的横坐标伸长为原来的2倍(纵坐标不变)，再将得到的图像向左平移π4个单位，得到函数y ＝g (x )的图像，求g (x )在⎣⎡⎦⎤－π4，3π4上的最小值． 解：(1)因为f (x )＝3sin ⎝⎛⎭⎫ωx －π3， 且f ⎝⎛⎭⎫π6＝0，所以ωπ6－π3＝k π，k ∈Z . 故ω＝6k ＋2，k ∈Z . 又0<ω<3，所以ω＝2.(2)由(1)得f (x )＝3sin ⎝⎛⎭⎫2x －π3， 所以g (x )＝3sin ⎝⎛⎭⎫x ＋π4－π3＝3sin ⎝⎛⎭⎫x －π12. 因为x ∈⎣⎡⎦⎤－π4，3π4，所以x －π12∈⎣⎡⎦⎤－π3，2π3， 当x －π12＝－π3，即x ＝－π4时，g (x )取得最小值－32. 20．(12分)如图，函数y ＝2sin(πx ＋φ)，x ∈R ⎝⎛⎭⎫其中0≤φ≤π2的图像与y 轴交于点(0,1)．(1)求φ的值；(2)求函数y ＝2sin(πx ＋φ)的单调递增区间；(3)求使y ≥1的x 的集合．解：(1)因为函数图像过点(0,1)，所以2sin φ＝1，即sin φ＝12.因为0≤φ≤π2，所以φ＝π6. (2)由(1)得y ＝2sin ⎝⎛⎭⎫πx ＋π6，所以当－π2＋2k π≤πx ＋π6≤π2＋2k π，k ∈Z ，即－23＋2k ≤x ≤13＋2k ，k ∈Z 时，y ＝2sin ⎝⎛⎭⎫πx ＋π6是增函数， 故y ＝2sin ⎝⎛⎭⎫πx ＋π6的单调递增区间为⎣⎡⎦⎤－23＋2k ，13＋2k ，k ∈Z . (3)由y ≥1，得sin ⎝⎛⎭⎫πx ＋π6≥12，所以π6＋2k π≤πx ＋π6≤5π6＋2k π，k ∈Z ，即2k ≤x ≤23＋2k ，k ∈Z ，所以y ≥1时，x 的集合为⎩⎨⎧⎭⎬⎫x ⎪⎪2k ≤x ≤23＋2k ，k ∈Z .。

(建议用时：40分钟)Ⅰ.阅读理解A(2020·成都诊断)For the past two years I have been travelling and living abroad. Home has become more of a feeling than a place. I feel at home when I am with my family in London, but I also feel at home in Italy with friends I love. Home is no longer a picture of a house with a front door and some windows. It is more complicated than that.This is one of the reasons that celebrating the new year has become very important for me. I do not care about “New Year’s resolutions(新年计划)”—living abroad has made me constantly reconsider what kind of person I want to be and how I will live my life, so I don’t feel the need to plan for change: I live for change.New Year’s Eve has become my time to reconnect with the friends, which makes me feel at home. Every year we try to reunite wherever we are, and remember the time when we knew each other so well that we felt like a family. It is a moment to reconnect and get to know each other again. Last year, we travelled to a cottage in Ireland where we had no Internet and no neighbours. In the middle of the countryside, away from our constantly changing lives, we were able to become like a little family again.This year, we went to Barcelona. It was a very big change. We were surrounded by culture and life and joy. There were bars and parties. It was different, but one thing stayed very much the same—I felt at home again and we felt like a family again.A lot of people feel that New Year’s Eve cannot live up to expectations. Ideas such as the “New Year’s kiss”and “resolutions”create a lot of pressure for people to have a night to remember, a night that will change their lives and perhaps make the next year worth living. I think those people are missing the point. Why can’t New Year be about friends?【解题导语】本文是一篇夹叙夹议文。

2019-2020学年高中语文人教版必修3配套习题：模块综合检测 Word版含解析
姓名，年级：时间：模块综合检测（时间：150分钟满分:150分)一、现代文阅读（36分）(一)论述类文本阅读(9分,每小题3分）阅读下面的文字，完成第1~3题.20世纪30年代,爱因斯坦等科学家在研究引力场方程时，假设宇宙中可能存在连接两个不同时空的狭窄隧道，这个隧道就是后来物理学家所说的虫洞。
爱因斯坦认为通过这个隧道即虫洞可以做瞬时的空间转移，如果虫洞的出口恰好停在过去，就可以通过它逆着时间旅行。
当然，进行这种时间旅行时你只能旁观,因为时间是线性的，事件就是一个个已经穿好的珠子,你无法改变珠子也无法调动其顺序。
但截至2013年,还尚未有实验证实虫洞真正存在.早在19世纪50年代,已有科学家对虫洞做过研究.一些物理学家认为,理论上,也许虫洞可以使用,但虫洞的引力过大,会毁灭所有进入的东西;同时，即使宇宙中充斥着数以百万计的虫洞，但也很少会有直径超过10万公里的，而这个宽度正是太空飞船安全航行的最低要求。
因此虫洞不太可能用于宇宙航行。
随着科技的发展,新的研究发现,虫洞的超强力场可以通过“负质量”来中和,起到稳定虫洞能量场的作用。
科学家认为,相对于产生能量的“正物质”，“反物质"拥有“负质量",可吸去周围所有能量。
目前世界上的许多实验室已经成功地证明了“负质量”能存在于现实世界，并且通过航天器在太空中捕捉到了微量的“负质量”.“负质量”的发现为利用虫洞创造了新的契机，只要用“反物质"去扩大原本细小的虫洞，并强化“虫洞”的结构,使其稳定,就可以让太空飞船穿过.与此同时,许多科学家也在致力于构造人工虫洞的研究。
科学家桑恩等人从理论上提出了构造虫洞的概念。
他们相信,先进文明所创造的人工虫洞,可以用奇异物质的“支柱”来保持虫洞的畅通。
奇异物质具有超过它能量密度的极大的负压，其引力具有排斥性，从而使得它周围的空间被扭曲得十分奇怪，这正好改变了空间扭曲的“符号”.桑恩的虫洞,可称为奇异物质虫洞。
