1.二年级数学上册7单元 篇一

表内乘法和表内除法

(二)——《7的乘法口诀》教学设计

教材分析:本节课是苏教版二年级第六单元《表内乘法和表内除法

(二)》第一课时的内容,表内乘法和表内除法是小学阶段最重要的基础知识之一,7的成分口诀的学习,为后面学习8、9乘法口诀打下基础。

设计理念:学生已经学了1-6的乘法口诀和相应的除法后,学生已经初步学会编乘法口诀的基础上,创设了吸引学生自主探索7的乘法口诀的活动情境,使学生在理解乘法口诀来源的基础上,进一步掌握编乘法口的方法,促进对乘法口诀的记忆。编制乘法口诀时,注意由师生共同编制逐步过渡到放手让学生独立完成。教学目标:

1、经历编制 7 的乘法口诀的过程,体验 7 的乘法口诀的来源。掌握口诀的特征,并熟记口诀。

2、让学生主动投入到学习中去,在活动中培养学生的探索精神,合作交流的意识。

3、经历知识形成的全过程,体验探究的乐趣;感受到数学与生活的密切联系,体验到生活中处处有数学。

教学重点:经历编制 7 的乘法口诀的过程。教学难点:掌握口诀的特征,并熟记口诀。教学准备:口算卡片 教学过程:

一、复习旧知

(一)复习1-6的乘法口诀。

1.谈话:老师为准备了红色帆船,想带着大家前往数学王国,你们想去吗?先考考你。请快速说出算式的结果,并说出对应的乘法口诀。

4×5= 6×3= 4×3= 2×5= 2×3=

2.谈话:同学们,口算的速度可真快。我们的扬帆起航啦!

【设计意图:复习1--6的乘法口诀及对应的算式,进一步巩固已学乘法口诀,帮助学生学生7的乘法口诀做好准备】

二、自主探究,创编口诀

(一)出示例题:红色小船 1.谈话:这只小船是由什么图形组成?有几个三角形组成呢?我们一起数数。

2:提问:1只小船是有7个三角形组成,表示“几个7”?2只小船有几个三角形组成呢?

小结:2只小船可以表示“2个7”,比“1个7”多7,只要在7的基础上加上7就可以了。交流:你能用这样的方法算出3只小船有多少三角形组成吗?

3.追问:那4只、5只、6只、7只小船呢?你会算吗?打开书70页,自己算一算。

独立完成,教师巡视。

4.汇报交流:3、4、5、6、7只小船有多少个三角形组成? 5.引导:算三角形个数时,你能想到什么? 小结:我们想到用7的乘法口诀,计算更快一些。6.揭题:今天我们就来学习7的乘法口诀。

(二)编7的乘法口诀

1.谈话:根据以往经验,7的乘法口诀有几句?如果让你编口诀,你们会吗? 引导:比如:1个7 1x7=7 一七得七

2.追问:你们会编吗?请同学打开书70页,试着编7的乘法口诀。生填写,汇报。

4.谈话:我们一起读一读7的乘法口诀。(板书:7的乘法口诀)

(三)记7的乘法口诀

1.提问:如果要记住这些口诀,你觉得哪几句口诀容易记忆住? 2.追问:哪几句口诀难记一些?你有什么好办法记住这些口诀? 小组内讨论,汇报。

谈话:其实记住口诀的方法有很多,只要我们多动脑、多动口,就一定能熟练的记住它。我给大家提个要求:不管三七二十一,每位同学都必须熟记,难道背这几句口诀还需要七七四十九天吗?

3.提问:老师在这里提到了7的乘法口诀吗?生活中我们常会使用这两句口诀,可以帮助同学们记忆。

4.追问:下面给大家1分钟的时间,能记住这些口诀吗? 个人背、集体背。

5.谈话:大部分同学已经能背出口诀,那我们做个游戏吧!我说口诀的前半句,你们说后半句。

6.小组或者同桌之前说一说

(四)运用7的乘法口诀

1.谈话:我们学习乘法口诀其实就是为了方便计算,比如:7×2= 2.追问:刚才还有哪一道算式使用7的乘法口诀?这说明这句口诀可以写出两道乘法算式。

谈话:在乘法算式中,不管7在前,还是7在后都是用7的乘法口诀。看来乘法口诀还是很重要的,我们再背一遍好吗? 学生背口诀。

3.谈话:看来同学们已经掌握了7的乘法口诀,那么我们就用所学的知识来完成智力大闯关活动吧!

【设计意图:通过摆小船需要多少个三角形的问题,组织学生计算几个7想家是多少,一方面引导学生初步记忆“几个7 ”相加的结果,另一方面启发学生具体感知得到的这些之间的联系,从而为学生编制和记忆口诀做准备。

在学习7的乘法口诀的过程中,放手让学生自主编制口诀,交流口诀拍了规律,探讨记忆口诀的方法。通过提供足够的自主学习的空间、充分的数学交流机会,使学生在探索数学知识的过程中,体验学习成功而快乐。】

三、巩固练习1.第一关

(1)你能根据乘法口诀说出对应的乘法算式吗? 追问:一句口诀可以说出几道乘法算式? 2.第二关

(1)谈话:请同学们先计算各题,打开书71页第1题。提问:你发现什么?得数为什么会一样呢?

小结:3个7加1个7是4个7,下面两题也表示4个7。

(2)谈话:谁能准确的看出第二组是几个7?,请完成书上第2题。出示:5个7比4个7 多(),比6个7少()。

3、第三关 独立完成第5题

4、第四关:游戏:芝麻开门 游戏规则:

(1)选择2位同学做“大门”,6位同学参加游戏;

(2)将由全班同学出题,如选手回答正确,大家可以说“芝麻开门”,选手方可通过;选手回答错误,大家可以说“芝麻关门”,选手将被淘汰。

【设计意图:熟记并能正确的进行相关的计算是本节课的重点,教师通过有趣的游戏展开练习,帮助学生巩固新知,促进记忆。也为了下节课自主探索7的乘法口诀求商的方法做好准备】

五、课堂总结

谈话:通过本节课的学习,你有什么收获?我们一起再背一遍7的乘法口诀。

六、板书设计

7的乘法口诀 一七得七 二七十四 三七二十一 四七二十八 五七三十五 六七四十二 七七四十九

七、教学反思

本节课我主要发挥学生已有的2-6的乘法口诀的基础知识进行迁移,引导学生自我完成对7的乘法口诀的探究、编制,学生在这个过程中体验数学收获的幸福。根据二年级学生的年龄特点,在课堂上,我力求调动学生学习兴趣,吸引学生注意力,在发展学习能力的同时让学生学得轻松愉快、扎实有效。

我就启发学生2×7表示2个7相加,所以学生在计算以后几个得数时都采用这种方法,为学生创编口诀搭建了脚手架,接着我就放手让学生进行口诀的编制,进行小组交流,利用集体的智慧,写出所编写的口诀,从后面口诀的汇报可 以看出我这一环节的编排是非常的成功的,学生完全可以独立编写出7的乘法口诀。

设计的“智力大创关”练习主要是对7的乘法口诀进行巩固,然对7的乘法口诀和算式进行综合练习,使练习有坡度,难度适宜,体现了让不同的学生在教学中得到不同的发展。学生动手、动脑、动口,人人主动参与学习,有效地培养了学习习惯,发展了学生的学习能力。

2.二年级数学上册7单元 篇二

第一次教学设计:

教学过程:

一、情境导入, 揭示课题

1.创设情境, 认识新朋友乐乐, 开始出现一张图猜猜谁 是乐乐。

2.跟乐乐进入数学王国碰到一扇密码门, 密码是由1、2和3组成的两位数, 每个两位数的十位数和个位数不能一样, 通过密码门就能进入数学王国。

通过小组合作, 交流汇报, 学生板演, 教师引导, 得出三组不同的排列方法:

第一组:12、21、13、31、23、32学生介绍自己的想法。

教师引导:你先选了哪两个数字调换位置?再选了哪两个数调换位置?揭示调换位置法。

第二组:12、13、21、23、31、32学生介绍自己的想法。

教师引导:先选1固定在十位上, 和剩下的2、3分别组成12、13;再选2固定在十位上, 和剩下的1、3分组成21、23;然后选3固定在十位上, 和剩下的1、2组成31、32。揭示固定十位法。

第三组:引导既然可以固定十位来摆数, 那是不是也可以固定个位摆数呢?

得出21、31、12、32、13、23学生介绍自己的想法。

教师引导:这种方法先选1固定在个位, 再选2固定在个位, 然后选3固定在个位, 分别和另外的两个数组成不同的数。可以把这种方法叫什么呢?揭示固定个位法。

教师小结:引导学生要有顺序的思考, 才能不重复不遗漏。

揭示课题并板书:排列与组合。

二、探究新知

1.握手问题。进入数学王国, 碰见两个新朋友, 想跟他们 握手表示友好, 每两个人握一次, 可以握几次。

2.吃点心问题。数学王国的小精灵看小朋友这么能干, 来给大家送点心了, 面包、包子、饼干, 送给三个小朋友各一种, 一共有多少种送法?

三、巩固学习

三个人拍照留念, 可以怎么排位子?

四、小结

你学会了什么?

第一次反思:教学设计要从教材内容编排出发。

旧版人教版小学数学中数学广角中第一课时把排列与组合放在一起, 而新人教版小学数学教材中, 数学广角的第一课时只有排列, 并没有组合的内容摄入。我在备课中, 没有仔细研究新教材, 理解新教材, 把握手问题和吃点心问题放进了第一课时, 这两个都是组合的典型例题, 因此我做出了修改。而在一开始的导入中, 我出示两个小朋友让学生猜谁是乐乐, 这个知识点也不符合本课要求, 因此删去。

第二次教学设计:

教学过程:

一、情境导入, 揭示课题

(删去谁是乐乐这个环节, 直接导入, 进入密码门, 其他一样。)

揭示课题并板书:排列。

二、探究新知

1.用红黄蓝三种颜色, 分别涂头和身子, 有多少种涂法? (我的出发点是想创新, 不用书中的涂北城南城的例子, 又为了方便做课件, 我设计了这样一个涂头和身子的例子。)

2.考考你?用 0、2、3 能组成几个不同的两位数?

(这个例题也是在第一次试教中教研员指出的一个对于新知识的练习。)

三、提升拓展

1.三个人拍照留念, 可以怎么排位子?

2.吃点心问题。 (变成排列问题, 三种点心按顺序先后 吃, 可以怎么选择?)

四、小结

说一说你学会了什么?

第二次反思:教学设计的案例要符合实际生活。

虽然这次试教发现了很多问题, 但是其中给我印象最深的就是我设计的用红黄蓝三种颜色, 分别涂头和身子, 有多少种涂法的问题。我的出发点是想与众不同, 没想到我的例题却出了问题, 试问世上哪有红色的头蓝色的身子呢?这个问题确实没有任何实际的意义, 也无法激起学生的学习兴趣。

数学来源于生活, 寓于生活, 并用于生活, 因此, 在数学教学中, 老师要以生活为背景, 真实的设计教学案例, 使学生把数学和生活紧密联系起来。

第三次教学设计:

教学过程:

一、情境导入, 揭示课题

揭示课题并板书:排列。

二、探究新知

1.考考你?用 0、2、3 能组成几个不同的两位数?

2.练习一: (课本中) 用 红、黄、蓝 3 种颜色给地图上 的两个城区涂上不同的颜色, 一共有多少种涂色方法?

3.练习二:从读、好、书三个字中任选 2 个字, 一共有多 少种选法?

4.练习三:从读、好、书三个字中任选 3 个字, 一共有多 少种选法?

4.二年级数学上册7单元 篇四

在我的身边,有许许多多的小伙伴,但我有一个非常要好的小伙伴她就是曾雨舒。她很喜欢撒娇,也很可爱,很天真,很活泼。

雨舒胖胖的,有着一个圆圆的大脸蛋,长着一头乌黑的长头发,梳成一个辫子。雨舒那浓浓的眉毛下,有着一双水灵灵而炯炯有神的大眼睛,眼睛下面有一个小鼻子。最可爱的就是她的那张嘴巴和那对小酒窝,她的那张嘴虽然不小,但是一些笑话和幽默的语句,就会从她的嘴里快乐地蹦出来。当她笑的时候,小酒窝就会呈现在你眼前,看,她笑得多灿烂呀!

雨舒的优点可多了,但她最好的优点就是爱看书,因此,她的知识非常丰富。记得有一次,她读三年纪的时候,刚上完课,同学们就一窝蜂似的跑出了教室,出去玩。同学们你追我赶的。我收拾好书,拿出下一堂课的书后,就出去玩了。玩了一会儿,我心里想:雨舒呢?搞了半天,也没见她一个人影。我又跑道教室里,只见雨舒刚拿出些课外书来看,便奇怪地想:这个雨舒也真是的,好好的下课不玩,却在这里看书。我想着,我便走到雨舒身边看了她一会儿,像只小鸟似的叽叽喳喳地说:雨舒,你也真是的,下课了不去玩,还在这儿读书。出来玩吧!

我说完,拉起雨舒的左手,正要走的时候,怎么拉也拉不走,那时,我就胡里糊涂地想:糟了,雨舒该不会是被谁给定住了吧!我回头一看,雨舒就用两眼直瞪着我,生气地对我说:我就是要读,这样才有知识。听了雨舒的话,我休得低下了头。

5.二年级数学上册7单元 篇五

扇形统计图

一、教学内容 扇形统计图

选择合适的统计图

二、教学目标

1.使学生了解扇形统计图的特点与作用,知道扇形统计图可以直观地反映部分数量占总数的百分比。

2.使学生能读懂扇形统计图,从中获取必要的信息,进一步体会统计在现实生活的作用。

3.使学生知道对于同样的数据可以有多种分析的方法,能根据需要选择合适的统计图,直观、有效地描述数据,进一步发展数据分析观念。

三、主要变化与具体编排

(一)主要变化

到本单元为止,学生已经学完了条形统计图、折线统计图、扇形统计图这三种统计图。因此,本单元除了让学生认识扇形统计图(例1)之外,又新增了一道让学生根据不同的统计目的选择不同统计图的例题(例2),使学生从整体上认识三种统计图各自的特点,理解这三种统计图在使用上各有什么优越性和局限性。

(二)具体编排 1.例1。

教材联系学生的生活实际,创设了学生在校园参加各种体育活动的情境,为引出有关统计数据提供现实背景。通过统计表中的数据提出对数据的进一步处理要求:你能算出喜欢每种运动人数各占全班人数的百分之几吗?以百分数意义的理解引出扇形统计图的教学。

教材让学生将统计表中的数据填入未完成的扇形统计图,让学生经历用不同大小的扇形表示各部分数量占总数百分比的过程,初步了解扇形统计图的特点。

在完成了扇形统计图后通过三个问题的思考,进一步引导学生在观察的基础上得出扇形统计图的特点:用扇形可以清楚地表示出最喜欢的各种运动项目的人数占全班总人数的百分比。

2.例2。

条形统计图、折线统计图和扇形统计图的特点各异,在实际应用中的适用条件也不一样,例2以三组校园树木数量相关数据,通过不同的统计内容让学生选择合适的统计图,在统计图的多样化与优化中进一步认识各统计图的特点。同时体会相同的统计对象,当需要表达的信息不同时,选择的统计图也不同,让学生进一步感受统计的价值,发展数据分析观念。

第(1)小题统计的是树木总量在2007~2011年之间的变化情况。既可用条形统计图,也可以用折线统计图。这一题对比的意图在于让学生体会条形统计图、折线统计图的特点,突出选择折线统计图的一般条件,即表示数据变化趋势时用折线统计图更直观。

第(2)小题统计的是各种树木占树木总量的百分比,既可以用扇形统计图,也可以用条形统计图表示。条形统计图只是直观呈现了各种树木数量占总数的百分之几,而扇形统计图能更直观、有效地看出校园树木数量的分布情况,突出选择扇形统计图的一般条件:当需要了解整体与部分之间的关系时,选择扇形统计图更合适。

第(3)小题统计的是各种树木的数量,教材中只出现条形统计图,引导学生思考“为什么不用其他的统计图”,在对比三种统计图特点的基础上突出选择条形统计图的一般条件:当只需要表示各项目的数据时,用条形统计图就可以了。

四、教学建议

1.结合生活中的统计实例进行教学,使学生充分感受统计的现实价值。2.使学生通过比较,认识各种统计图的适用性和局限性。

节约用水

一、教学内容

通过对水龙头漏水情况的调查,了解水资源浪费情况,提出节约用水的具体建议并落实在行动中。

二、教学目标

1.通过测量等操作活动,让学生经历收集、整理、分析数据的过程。

2.使学生综合运用所学的数学知识、技能和方法科学地认识日常生活中水资源浪费的问题。

3.使学生加强环保意识,并把节约用水落实到行动上。

三、具体编排

本活动包含以下环节。(1)收集信息。

通过板报的形式给出地球水资源的一些统计信息,通过这些信息让学生认识到我国水资源匮乏,帮助学生认识到节约用水的重要意义。在此基础上让学生收集相关的信息:(1)观察生活中浪费水的现象,实际调查一下学校或家里漏水水龙头的数量。(2)选择其中一个漏水的水龙头,测量出它一定时间漏水的量。(3)通过多种途径收集节约用水的资料。

(2)分析数据。

小组同学合作对收集到的一定时间水龙头漏水的量进行测量分析,计算出水龙头每分钟漏水的速度。然后,对各组的分析结果进行比较,并针对比较的结果进行小组讨论:“收集到的水龙头漏水速度不一样,怎样表示全班同学调查到的水龙头漏水的一般水平比较恰当?”

(3)解决问题。

在上述数据分析的基础上,通过把有限样本得出的结论进一步类推到更大的样本,解决教材提出的问题,帮助学生对生活中浪费水的现象有一个客观而量化的认识。

(4)提出方案。

对课前收集的节约用水的资料进行讨论交流,提出具体的节约用水的方案,加强学生的环保教育。

四、教学建议

6.二年级数学上册7单元 篇六

生活处处有语文吗?对于这个问题,我进行了深入的思考

人与人的交流,无非是语言与文字两种方式。在这两种方式中,用的都是字词、语句,你说的每一句话,都是有语文中的字词组成的。若你在语文阅读中能够积累更多的好词妙句,那么你的语言将添上色彩。除此之外,语文阅读中应该深入理解,领悟每一个词、每一句话、乃至每一段,阅读报纸、与人聊天时才不会出现不明不白、走马观花的情况。例如:别人讲了一句:那家伙两面三刀,绝对信不过!你连两面三刀都不知道什么意思,就只好不懂装懂地点点头,应和声:对呀!这样,你也只能怪自己没有学好语文了。

除了人与人的交流以外,语文还是我们情感的调味料。在你失落时,一篇优美的写景散文可以让你的身心在美的意境中陶醉,喜悦的浪潮将湿润你的心灵,将原本的悲伤、失落抛之脑后;当你十分愉快时,一篇抒情悲壮的文章将在你的心中掀起万丈波涛,给予你心灵最大的震撼,让你黯然泪下。由此可见,语文还能调制你的生活的味道。

语文是人与人之间交流的工具,是生活情感的调味料,还是生活的指路灯。对于这一点,我深有感触。当我被别人误会时,《论语》中孔子说过的一句话人不知而不愠,不亦君子乎?让我恍然大悟:对呀,清者自清!我又何必在乎别人的看法呢?我应该做一回君子!当我觉得理想过于遥远,似乎无法实现时,流沙河先生笔下的《理想》告诉我:理想有时候又是海天相接的弧线,可望不可即,折磨着你那进取的心。不对,理想要折磨我,我怎能轻易屈服呢?它越要折磨我,我就越要取得成功给它看。于是我马上握住笔,开始奋斗!当语文总能在我迷路时,告诉我方向,让我更好地生活。

To be sure, only children experience some things differently from those with siblings(兄弟姐妹). Many feel more pressure to succeed. In the absence of brothers and sisters, only children are also likely to look more exclusively(独有地) to their parents as role models.

In India, 19-year-old Saviraj Sankpal founded a support group for the tiny number of only children. Among other things, the group does volunteer work to be against the myth(神话) that they’re irresponsible(不负责任的). “People think we’re pampered(娇惯) and spoiled,” says Sankpal, a computer-engineering student. “But I’d like to remind them how lonely it can get.”

Most only children, however, say they wish for brothers and sisters only when it comes to caring for aged, unhealthy parents.

Britain’s David Emerson, author of the book The only child, says that such a person bears terrible burden in having to make all the decisions alone. Emerson knows from experience: after his father died, he chose to move his elderly mother from their family home, where she was vulnerable(易受攻击的) to house breakers, to a new one with more safety. “The move was quite hard on her, and she might feel that I pushed her into it,” he says. “Finally, I am left with that responsibility.”

In the future, more and more only children will likely face similar choices. With working mothers increasing, many families are finding they simply don’t have the time, money or energy to have more than one child. As only children become common, perhaps the world will realize that the accusation(指责) made against them is unfair.

11. It can be inferred from the passage that only children’s parents should ____.

A. found a support group for their only children

B. do volunteer work to help their only children

C. let their only children make all the decisions alone

D. set good examples for their only children

12. Emerson decided to move his elderly mother to a new house because he ____.

A. is the only one who cares about her

B. is worried about her safety

C. wants to share the responsibility with her

D. doesn’t want to leave her alone

13. It is quite usual now for a working mother to ____.

A. spend all her time and money on her only child

B. be responsible for bringing up her only child

C. have and bring up only one child

D. put all her energies on her job

14. The main idea of the passage is that ____.

A. only children are spoiled and irresponsible

B. only children have to face many difficulties

C. most only children want to have brothers and sisters

D. most only children share their responsibilities with their parents

Most of us are used to four seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.

A new study from Switzerland, sheds light on(使某事清楚明白地显示出来) where ice sheets(冰川) melted during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions(区域).

This surprised the researchers from the University of Bern(波恩大学). Scientists have long assumed(假设) that most of the ice that melted was in the Northern Hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up.

The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence(证据) of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern Hemisphere that ice melted, there would have been a bigger impact(影响) on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern Hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.

It is still a mystery(神秘的事物) as to what caused the temperature changes that caused the ice to melt.

15. The North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. So scientists thought that ____.

A. most of the ice melted in the Northern Hemisphere

B. most of the ice melted in the Southern Hemisphere

C. the North Pole is colder than South Pole

D. the South Pole is colder than North Pole

16. We can infer from the passage ____.

A. the ice can easily just slip into the ocean

B. volcanoes caused the ice to melt

C. melting just in the Northern Hemisphere would have beenimpossible

D. researchers often use the computer models to help their researchwork

17. The scientists are not sure ____.

A. how long the ice age lasted

B. where ice sheets(冰川) melted during the ice age

C. what caused the temperature changes

D. what the earth is made up of

18. Which of the following is the best title?____.

B. Studies Show Ice Melted Equally in the North and the South

During the Ice Age

C. Most of the Ice Melted in the Northern Hemisphere(半球) Duringthe 30,000-year-long Ice Age

Ⅳ.阅读表达

黄石国家公园天气变化快,昼夜温差大,让我们走进下文感受这一点。Yellowstone Weather

Yellowstone National Park is at high altitude(海拔). Most of the park is above 7,500 feet (2,275 meters).

Yellowstone’s weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. So it is best to come prepared for cold evenings and mornings, especially if you are camping or hiking. When you leave your campsite, please leave it prepared for possible thundershowers and wind.

A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, an easy day hike or boat trip can turn into a battle for survival.

1. What kind of weather does Yellowstone have?

2. What decides Yellowstone’s weather?

3. If you are planning to spend your holidays in Yellowstone National Park in summer, what should you take with you?(不超过8个词)

4. What does the underlined word “readings” refer to?

5. What can be put in the blank with “?” (不超过5个词)

6. Here are some questions on how to ask about the weather elements of a place. Read these questions and fill in a word in each blank according to its first letter.

(1) What is the a____ temperature in your hometown?

(2) How o____ does it rain in your hometown?

(3) What is the d____ season in your hometown?

(4) Is your hometown often s____ by flood?

(5) What are the h____ months in your hometown?
