高三英语二轮复习专题一 强化练(七)

强化练(七)主旨大意题(2)Ⅰ.阅读理解A(2023·浙江五校联考)On Mondays, two of my children get ready for school in an unusual way.Each packs plenty of food and water, a pair of rubber boots and sometimes a cup of hot chocolate.Then, I drop them off at a nearby park where they spend the entire day outside at a certified forest school.When I first let them sign up for the forest school program,I loved the idea, but as a mum,I was concerned about a few things: Would they be comfortable outside for that long? Would they stay engaged for that many hours? Then I asked them if time ever seemed to move slowly,they stared at me in confusion.They didn't understand my question, which fittingly removed my concern.In this program, kids direct their own play,climbing tall trees or testing ice on the frozen lake.They are never told their play is too high or too sharp, but are rather trusted toself-adjust.Something else my sons appreciate about the forest school is not being told to move on to the next activity, but being left to stay in a particular spot for as long as their curiosity allows.“What about all the things they're missing in real school?”concerned parents have asked me.Neither of their classroom teachers thinks it's a problem, but most significantly, my kids are learning new and different skills that a classroom cannot teach.They are learning to sit silently and observe nature up close—a skill that's virtually impossible to develop in a noisy and overcrowded classroom setting.They are making social connections across a broader range of age groups.They cooperate together, using their different sizes and strengths to fulfill various roles within their games.I appreciate it that the forest school is shaping my boys' relationship with theoutdoors.They're learning how to spend extended periods of time in nature, what to do to pass the time,and developing knowledge that will get them much closer to nature in the coming decades.1.What is special about the forest school program?A.Teachers engage in kids' play.B.Kids play and learn outdoors.C.It focuses on nature protection.D.It offers various foods and drinks.2.How did the author feel about kids' reaction to her question?A.Awkward. B.Concerned.C.Relieved. D.Proud.3.What does Paragraph 4 mainly talk about?A.The concerns caused by the program.B.The benefits gained from role-play.C.The skills acquired by children.D.The games loved by teachers.4.What can be a suitable title for the text?A.Nature:a Wonderland for the YoungB.The Forest School Program Proves a HitC.Parks Are Replacing Traditional SchoolsD.Forest School:a Fine Place for My Kids[语篇解读]本文主要讲述了作者的两个儿子在森林学校项目中的收获以及该项目的好处。

[5]It is obvious that the way much coffee is grown affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
[4]In the evening, rides are usually at a more relaxed and unhurried pace, with golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

语音专题7: r音,re音节和成音节的发音

语音专题7: r音,re音节和成音节的发音

语音专题7:r音节, re音节和成音节的发音一、-r音节,也就是“元音字母+r”所构成的音节,一共有五个:ar, er, ir, or, ur。

请看它们在重读音节和非重读音节中的读音规则。

1. ar的读音有三种:a. ar常发/a:/:arm, party, farm, farmer, garden, market, parkb. 在/w/后常发/ɔ: /:warm(暖和的)c. 在非重读音节中ar发/ə/:dollar2. er也有三种发音:a. 在重读音节中发长元音/ə:/:her, dessert;特例:clerk /a:/b. 在非重读音节中er却发短元音/ə/:answer, computer, daughter, concert, summer, shower, exercise /'eksəsaiz/, tiger, under, father, mother, brother, sister,driver, river3. ir一般都发/ə:/:dirty, first, shirt, thirty, thirteen, skirt, bird, birthday4. or有三种读音:a. 在重读音节中常发/ɔ:/:for, sport, short, shorts, morning, born, horse;特例:airport中or是在非重读音节里,但也发/ɔ:/b. 在/w/后or却发/ə:/:word, work, worker, worldc. 在非重读音节中发短元音/ə/:color, actor, doctor, neighborhood5. ur的读音有两种:a. 在重读音节中发/ə:/:Thursdayb.在非重读音节中发短元音/ə/:Saturday, survey注意:hurry中有两个r,怎么办呢?是这样的,当元音字母后面有两个r时,我们不能把其中的“元音字母+r”看作-r音节,而只能当作元音字母在重读闭音节中的发音,因此hurry中的u发/ʌ/。

2.探究加速度与力、质量的关系:实验中应思考解决好以下三个问题:(1)怎样测量(或比较)物体的加速度(2)怎样提供和测量物体所受的恒力(3)怎样由实验数据得出结论。

【分类典型例题】
题型一:运动基本概念的辨析与匀变速直线运动基本规律的应用
解决这类问题需要注意:这类习题最大的特点就是解法较多,选择一个较好的方法可以又快又准确地得到回答,关键是对基本概念、基本规律深入的理解与掌握。

虽然这类习题在高考试题中单独出现的可能性较小,但是在综合题中却是非常重要的环节,是完整给出正确答案的基础。

[例1]做匀加速直线运动的物体,依次通过A、B、C三点,位移sAB=sBC,已知物体在AB段的平均速度大小为3m/s,在BC段的平均速度大小为6m/s,那么物体在B点的瞬时速度大小为A.4m/s B.4.5m/s C.5m/s D.5.5m/s
[变式训练1]物体以速度v匀速通过直线上的A、B两点间,需时为t。

现在物体由A 点静止出发,匀加速(加速度为a1)运动到某一最大速度vm后立即作匀减速运动(加速度为a2)至B点停下,历时仍为t,则物体的
A.vm只能为2v,无论a1、a2为何值B.vm可为许多值,与a1、a2的大小有关C.a1、a2值必须是一定的D.a1、a2必须满足
题型二:追及与相遇的问题
解决这类问题需要注意:画出示意图来表明两个物体追及过程中的空间关系,特别注意的是两个物体相遇时的临界条件。

[例2]在一条平直的公路上,乙车以10m/s的速度匀速行驶,甲车在乙车的后面做初速度为15m/s,加速度大小为0.5m/s2的匀减速运动,则两车初始距离L满足什么条件可以使(1)两车不相遇;(2)两车只相遇一次;(3)两车能相遇两次(设两车相遇时互不影响各自的运动)。

25为临界值
题型三:牛顿定律与图象的综合应用。

解决这类问题需要注意:利用图象分析研究对象的受力特点
以及运动性质,然后结合题意运用牛顿第二定律。

[变式训练3]放在水平面上的物块,受到方向不变水平推力F的作用,F与时间t的关系和物块速度v与时间t的关系如图所示,取重力加速度g=10 m/s2。

由此两图线可以求得物块的质量m和物块与地面之间的动摩擦因数分别为A
A.m=0.5kg,u=0.4 B.m=1.5kg,u=2/15 C.m=0.5kg,=0.2 D.m=1kg,u=0.2
题型四:连接体问题
解决这类问题需要注意:若连接体内(即系统内)各物体具有相同的加速度时,应先把连接体当成一个整体(即看成一个质点),分析其受到的外力及运动情况,利用牛顿第二定律求出加速度.若连接体内各物体间有相互作用的内力,则把物体隔离,对某个物体单独进行受力分析(注意标明加速度的方向),再利用牛顿第二定律对该物体列式求解。

[例4]如图所示,一辆汽车A拉着装有集装箱的拖车B,以速度v1=30 m/s进入向下倾斜的直车道。

车道每100 m下降2 m。

为了使汽车速度在s=200 m的距离内减到v2=10 m/s,驾驶员必须刹车。

假定刹车时地面的摩擦阻力是恒力,且该力的70%作用于拖车B,30%作用于汽车A。

已知A的质量m1=2000 kg,B的质量m2=6000 kg。

求汽车与拖车的连接处沿运动方向的相互作用力。

取重力加速度g=10 m/s2。

[变式训练4]如图所示,在粗糙水平桌面上放有A、B两个物体,A、B间用一根轻质硬杆C 相连,已知物体A的质量是m1=5kg,B的质量是m2=3kg。

A与桌面的动摩擦因数是μ1=0.2,B与桌面间的动摩擦因数是μ2=0.5。

现在A上施加水平向右的拉力F,使它们以v=10m/s的速度沿水平面向右匀速运动。

已知g取10m/s2,
求:(1)水平向右的拉力F的大小及轻杆C上的弹力大小;15N
(2)若在某时刻突然撤去拉力F,则A、B在水平面上滑动的距离是多大?16m
题型五:弹簧变化过程中运动分析
解决这类问题需要注意:弹簧的弹力是一种由形变决定大小和方向的力,注意弹力的大小与方向时刻要与当时的形变相对应。

一般应从弹簧的形变分析入手,先确定弹簧原长位置、现长位置及临界位置,找出形变量x与物体空间位置变的几何关系,分析形变所对应的弹力大小、方向,弹性势能也是与原长位置对应的形变量相关。

从此来分析计算物体运动状态的可能变化。

通过弹簧相联系的物体,有运动过程中经常涉及临界极值问题:如物体的速度达到最大;弹簧形变量达到最大;使物体恰好离开地面;相互接触的物体恰好脱离等。

此类问题的解题关键是利用好临界条件,得到解题有用的物理量和结论。

[例5]如图所示,A、B两木块叠放在竖直轻弹簧上,已知木块A、B质量分别为0.42kg 和0.40kg,弹簧的劲度系数k=100N/m,若在木块A上作用一个竖直向上的力F,
使A由静止开始以0.5m/s2的加速度竖直向上做匀加速运动(g=10m/s2)。

求:
(1)使木块A竖直做匀加速度运动的过程中,力F的最大值;
(2)若木块由静止开始做匀加速运动,直到A、B分离的过程中,弹簧的弹性势能减少了0.248J,求这一过程中F对木块做的功。

[变式训练5]竖直放置的轻弹簧,上端与质量为3kg的物块B相连接。


一个质量为1kg的物块A放在B上。

先向下压A,然后释放,A、B共同向上运动一段路程后将分离。

分离后A又上升了0.2m到达最高点,此时B的速度方向向下,且弹簧恰好为原长。

则从A、B分离到A上升到最高点过程中,弹簧弹力对B做功的大小及弹簧回到原长时B的速度大小。

(取g=10m/s2)B
A.12J,2m/s B.0,2m/s C.0,0 D.4J,2m/s。
