初一典范英语学案7(1-6) - 副本
太原市外国语学校七年级典范英语导学案Book7(1-6)初一年级组2021.09致家长和学生关于这套书：《典范英语》中每一本均是一个生动有趣，极富内涵的小故事，在引人入胜的情节中，用故事激发学生学习英语的兴趣，同时，扩大词汇量，提高阅读能力。
而其本身作为英国血红色呢个学习母语的材料，体现了地道的英语文化，有别于学生了解文化差异，培养学生的想象能力和思维能力，提高综合语言素养。
关于学习目标：它和学校统编课本的侧重点不同：统编课本以夯实基础知识为主，而《典范英语》侧重于扩大学生的阅读量，培养学生语感，提高学生“读”的能力：如朗读，阅读，泛读的能力。
关于学习方法的建议：行有意义的内容出发，以内容为核心，了解故事大意，用讲故事的方法学习英语。
具体如下：1.朗读方面：大声跟读，模仿CD中的语音，语速和语调。
2.泛读方面：不需要逐一查出不认识的单词的意思，而要学会通过文章题目，图片或上下文等线索猜测词意、句义。
3.阅读方面：采用整进整出的方式，从中自然吸收语言。
而非细扣词语、语法等内容。
4.角色扮演、表演方面：通过实践，进入人物内心世界，在语境中培养“说”的兴趣，体会成功的乐趣。
5.关于日常要求：每天抽出10--20分钟大声朗读《典范英语》，每周完成一部作品，并开展各种语言实践活动，如通过复述、讨论、改写、续编。
自创等方式来进一步学习。
最后，我们相对同学们说：在刚接触《典范英语》时，你可能会遇到很多困难，感到无所适从。
但如果你有恒心，有毅力，紧跟老师，坚持一段时间后，你会欣喜的发现自己的阅读能力提高了！随着知识和能力的积累和提升，读书会变得越来越轻松愉快！愿同学们学习顺利，在“读”的过程中不断超越自我！Good English 7-1……Walrus joins in导学案This is a story about ANIMALS.

1.5.1全称量词与存在量词【学习目标】1．能够记住全称量词和存在量词的概念．2．学会用符号语言表达全称量词命题和存在量词命题，并判断真假．3．理解全称量词命题、存在量词命题与其否定的关系，能正确对含有一个量词的命题进行否定．【要点梳理】1．全称量词与全称量词命题2.存在量词与存在量词命题【思考诊断】1．x>2是命题吗？对任意的x∈R，x>2是命题吗？2．全称量词命题和存在量词命题中是否一定含有全称量词和特称量词？3．判断正误(正确的打“√”，错误的打“×”)(1)在全称量词命题和存在量词命题中，量词都可以省略．()(2)“三角形内角和是180°”是存在量词命题．()(3)“有些三角形没有内切圆”是存在量词命题．()(4)内错角相等是全称量词命题．( )【课堂探究】题型一 全称量词命题与存在量词命题【典例1】 判断下列语句是全称量词命题，还是存在量词命题．(1)凸多边形的内角和等于360°；(2)有的力的方向不定；(3)矩形的对角线不相等；(4)存在二次函数y ＝ax 2＋bx ＋c 与x 轴无交点．[规律方法]判定命题是全称量词命题还是存在量词命题，主要方法是看命题中含有全称量词还是存在量词．要注意的是有些全称量词命题并不含有全称量词，这时我们就要根据命题涉及的意义去判断．[针对训练]1．用全称量词或存在量词表示下列语句(1)不等式x 2＋x ＋1>0恒成立；(2)当x 为有理数时，13x 2＋12x ＋1也是有理数； (3)方程3x －2y ＝10有整数解；(4)若一个四边形是菱形，则这个四边形的对角线互相垂直．题型二判断全称量词命题的真【典例2】判断下列全称量词命题的真假．(1)任意实数的平方均为正数．(2)函数y＝kx＋b为一次函数．(3)同弧所对的圆周角相等．(4)∀x∈R，x2＋3≥3.[规律方法]判断全称量词命题真假的方法要判定一个全称量词命题为真命题，需要进行推理证明，或用前面已经学过的定义、定理作证明，而要判断其为假命题，只需举出一个反例即可．[针对训练]2．判断下列全称量词命题的真假．(1)对每一个无理数x，x2也是无理数．(2)末位是零的整数，可以被5整除．(3)∀x∈R，有|x＋1|>1.题型三存在量词命题真假的判断【典例3】判断下列存在量词命题的真假．(1)有的集合中不含有任何元素．(2)存在对角线不互相垂直的菱形．(3)∃x∈R，满足3x2＋2>0.(4)有些整数只有两个正因数．[规律方法]判断存在量词命题真假的方法判断存在量词命题“∃x∈M，p(x)”的真假性的关键是探究集合M中x的存在性．若找到一个元素x∈M，使p(x)成立，则该命题是真命题；若不存在x∈M，使p(x)成立，则该命题是假命题．[针对训练]3．判断下列存在量词命题的真假．(1)有些二次方程只有一个实根．(2)某些平行四边形是菱形．(3)存在实数x1、x2，当x1<x2时，有x21>x22.题型四含有量词的命题的应用【典例4】已知命题“∀1≤x≤2，x2－m≥0”为真命题，求实数m的取值范围．[变式]若把本例中的“∀”改为“∃”，其他条件不变，求实数m的取值范围．[规律方法]求参数范围的2类题型(1)全称量词命题的常见题型是“恒成立”问题，全称量词命题为真时，意味着命题对应的集合中的每一个元素都具有某种性质，所以利用代入可以体现集合中相应元素的具体性质；也可以根据函数等数学知识来解决．(2)存在量词命题的常见题型是以适合某种条件的结论“存在”“不存在”“是否存在”等语句表述．解答这类问题，一般要先对结论作出肯定存在的假设，然后从肯定的假设出发，结合已知条件进行推理证明，若推出合理的结论，则存在性随之解决；若导致矛盾，则否定了假设．[针对训练]4．是否存在实数m，使不等式m＋x2－2x＋5>0对于任意x∈R恒成立，并说明理由．5．若存在一个实数x，使不等式m－x2－2x＋5>0成立，求实数m的取值范围．【课堂小结】1．判断全称量词命题的关键：一是先判断是不是命题；二是看是否含有全称量词．2．判定全称量词命题的真假的方法：定义法：对给定的集合的每一个元素x，p(x)都为真；代入法：在给定的集合内找出一个x，使p(x)为假，则全称量词命题为假．3．判定存在量词命题真假的方法：代入法，在给定的集合中找到一个元素x，使命题p(x)为真，否则命题为假.【随堂巩固】1．下列命题中，不是全称量词命题的是()A．任何一个实数乘0都等于0B．自然数都是正整数C．对于任意x∈Z,2x＋1是奇数D．一定存在没有最大值的二次函数2．下列命题中，存在量词命题的个数是()①有些自然数是偶数；②正方形是菱形；③能被6整除的数也能被3整除；④任意x∈R，y ∈R，都有x2＋|y|>0.A．0 B．1C．2 D．3A．有一个x∈R，使得x2>3B．对有些x∈R，使得x2>3C．任选一个x∈R，使得x2>3D．至少有一个x∈R，使得x2>34．对任意x>8，x>a恒成立，则实数a的取值范围是________．5．判断下列命题是全称量词命题还是存在量词命题？并判断其真假．(1)∃x∈R，|x|＋2≤0；(2)存在一个实数，使等式x2＋x＋8＝0成立；(3)在平面直角坐标系中，任意有序实数对(x，y)都对应一点．【参考答案】【要点梳理】1．全称量词与全称量词命题∀ 全称量词 ∀x ∈M ，p （x ）2.存在量词与存在量词命题∃ 存在量词 ∃x ∈M ，p （x ）【思考诊断】1．【答案】x >2不是命题，不能判断真假，而对任意的x ∈R ，x >2则是命题2．【答案】命题“正方形是特殊的菱形”，该命题中没有全称量词，即全称量词命题不一定含有全称量词3．【答案】(1)× (2)× (3)√ (4)√【课堂探究】题型一 全称量词命题与存在量词命题【典例1】[解] (1)可以改为所有的凸多边形的内角和等于360°，故为全称量词命题．(2)含有存在量词“有的”，故是存在量词命题．(3)可以改为所有矩形的对角线不相等，故为全称量词命题．(4)含有量词“存在”，是存在量词命题．[针对训练]1．[解] (1)对任意实数x ，不等式x 2＋x ＋1>0成立．(2)对任意有理数x ，13x 2＋12x ＋1是有理数． (3)存在一对整数x ，y ，使3x －2y ＝10成立．(4)若一个四边形是菱形，则所有这样菱形的对角线互相垂直.题型二 判断全称量词命题的真【典例2】[解] (1)假命题．若这个实数为0，则其平方为0，不是正数．所以“任意实数的平方均为正数”为假命题．(2)假命题．当k ＝0时，y ＝kx ＋b 不是一次函数，为常函数．所以“函数y ＝kx ＋b 为一次函数”是假命题．(3)真命题．根据圆周角的性质可知其为真命题．(4)真命题．∀x∈R，x2≥0，故有x2＋3≥3成立．[针对训练]2．[解](1)因为2是无理数，但(2)2＝2是有理数，所以全称量词命题“对每一个无理数x，x2也是无理数”是假命题．(2)因为每一个末位是零的整数，都能被5整除，所以全称量词命题“末位是零的整数，可以被5整除”是真命题．(3)当x＝0时，不满足|x＋1|>1，所以“∀x∈R，有|x＋1|>1”为假命题．题型三存在量词命题真假的判断【典例3】[解](1)由于空集中不含有任何元素．因此“有的集合中不含有任何元素”为真命题．(2)由于所有菱形的对角线都互相垂直．所以不存在对角线不垂直的菱形．因此存在量词命题“存在对角线不互相垂直的菱形”为假命题．(3)∀x∈R，有3x2＋2>0，因此存在量词命题“∃x∈R,3x2＋2>0”是假命题．(4)由于存在整数3只有正因数1和3.所以存在量词命题“有些整数只有两个正因数”为真命题．[针对训练]3．[解](1)由于存在二次方程x2－4x＋4＝0只有一个实根，所以存在量词命题“有些二次方程只有一个实根”是真命题．(2)由于存在邻边相等的平行四边形是菱形，所以存在量词命题“某些平行四边形是菱形”是真命题．(3)当x1＝－2，x2＝1时有x21>x22，故“存在实数x1、x2，当x1<x2时，有x21>x22”为真命题.题型四含有量词的命题的应用【典例4】[解]∵“∀1≤x≤2，x2－m≥0”成立，∴x2－m≥0对1≤x≤2恒成立．又y＝x2在1≤x≤2上y随x增大而增大，∴y＝x2－m的最小值为1－m.∴1－m≥0.解得m≤1.∴实数m的取值范围是{m|m≤1}．[变式][解]∵“∃1≤x≤2，x2－m≥0”成立，∴x2－m≥0在1≤x≤2有解．又函数y＝x2在1≤x≤2上单调递增，∴函数y＝x2在1≤x≤2上的最大值为22＝4.∴4－m≥0，即m≤4.∴实数m的取值范围是{m|m≤4}．[针对训练]4．[解]不等式m＋x2－2x＋5>0可化为m>－x2＋2x－5＝－(x－1)2－4.要使m>－(x－1)2－4对于任意x∈R恒成立，只需m>－4即可．故存在实数m使不等式m＋x2－2x＋5>0对于任意x∈R恒成立，此时需m>－4. 5．[解]不等式m－(x2－2x＋5)>0可化为m>x2－2x＋5.令t＝x2－2x＋5，若存在一个实数x使不等式m>x2－2x＋5成立，只需m>t min.又t＝(x－1)2＋4，∴t min＝4，∴m>4.所以所求实数m的取值范围是{m|m>4}．【随堂巩固】1．【解析】D选项是存在量词命题．【答案】D2．【解析】命题①含有存在量词；命题②可以叙述为“所有的正方形都是菱形”，故为全称量词命题；命题③可以叙述为“一切能被6整除的数也能被3整除”，是全称量词命题；命题④是全称量词命题．故有1个存在量词命题．【答案】B3．【解析】“∀x∈R，x2>3”是全称量词命题，改写时应使用全称量词．【答案】C4．【解析】∵对于任意x>8，x>a恒成立，∴大于8的数恒大于a，∴a≤8.【答案】a≤85．[解](1)存在量词命题．∵∀x∈R，|x|≥0，∴|x|＋2≥2，不存在x∈R，使|x|＋2≤0.故命题为假命题．(2)存在量词命题．∵x 2＋x ＋8＝⎝⎛⎭⎫x ＋122＋314>0，∴命题为假命题． (3)在平面直角坐标系中，任意有序实数对(x ，y )与平面直角坐标系中的点是一一对应的， 所以该命题是真命题．。

Module7语法学案 英语八年级上册
M7语法学案——过去进行时（1）一．语法梳理。
我们已经学习了四种基本时态，一般情况下“昨天晚上我在看电视”用时态那么我们表达“昨天晚上8点我在看电视”“当时我在操场上打篮球”这样情况用时态。
例句: ---- What were you doing at 7 am yesterday?昨天早上7点你在做什么?-----I was having breakfast.我在吃早餐。
一般来说，要表示过去或正在进行的动作，我们常使用时。
常和过去进行时连用的时间状语有:then,at this/that time yesterday,st night等, 过去进行时除了表示“”之外，还常常出现在的语境中，请看本模块的句子: Alice was sitting with her sister by the rive..爱丽丝正和姐姐坐在河边It was siting in a tree and smiling at everyone.它(那只猫)正坐在树上，朝着大家微笑。
They were having a tea party in the garden.他们正在花园里举行茶会。
过去进行时句子中的谓语部分由“was/were+动词”构成，与现在进行时结构相似，只是现在进行时中的am/is/are变成了。
由此同学们可以推断，过去进行时的句式变化也应该与现在进行时的一样。
句型转换：I was reading a book at that time?否定句：疑问句：肯定回答：否定回答：特殊疑问句（划线部分提问）：We were having a party at nine last night.否定句：疑问句：肯定回答：否定回答：特殊疑问句（划线部分提问）：You were sleeping then.否定句：疑问句：肯定回答：否定回答：特殊疑问句（划线部分提问）：She was sitting with her sister by the river.否定句：疑问句：肯定回答：否定回答：特殊疑问句（划线部分提问）：They were playing basketball at 4 pm yesterday.否定句：疑问句：肯定回答：否定回答：特殊疑问句（划线部分提问）：过去进行时和一般过去时区分：Laura was reading a novel at eight o'clock last night.昨晚8点劳拉在看小说。
