This garden is not like any other; it’s enchanted, filled with magical creatures and plants that whisper secrets of the past. The garden’s entrance is guarded by a m ajestic oak tree, its branches stretching out to form a natural archway. Only those pure of heart can pass through the barrier that surrounds the garden, a barrier that keeps away all who seek to harm or exploit its beauty.Within the garden, a crystal-clear pond reflects the sky above, while a rainbow of butterflies dances around fragrant flowers. The air is filled with the sweet melody of birdsong, and if one listens closely, they can hear the soft hum of fairies tending to their duties. At the center of the garden stands a stone fountain, where a statue of a mermaid sprays water into the air. It is said that the water from this fountain has healing properties, capable of curing any ailment.The garden changes with the seasons, offering different wonders throughout the year. In spring, delicate cherry blossoms cover the trees, while in summer, fruits ripen under the warm sun. Autumn brings a carpet of gold and red leaves, and winter transforms the garden into a winter wonderland, with snowflakes delicately adorning every branch and leaf.Those lucky enough to visit the enchanted garden are forever changed. They return to the world outside with a newfound appreciation for nature’s magic and the importance of preserving such sanctuaries.Questions:1.What is the main feature of the garden described in the passage?Answer: The main feature of the garden is its enchantment, which includes magical creatures, whispering plants, and a barrier that protects it from those who would harm it.2.Describe the entrance to the garden.Answer: The entrance to the garden is guarded by a majestic oak tree whose branches form a natural archway.3.What special property does the water from the fountain have?Answer: The water from the fountain has healing properties, capable of curing any ailment.4.How does the garden change during autumn?Answer: During autumn, the garden is covered in a carpet of gold and red leaves.5.What effect does visiting the enchanted garden have on people?Answer: Visiting the enchanted garden leaves people with a newfound appreciation for nature’s magic and the importance of preserving such sanctuaries.Each question is worth four points. The total possible score for this section is twenty points.五、作文(30分)Oxford Edition Year 8 Summer Holiday Writing AssessmentSection V: Writing(30 points)Instructions:You are required to write a short essay on the topic provided below. Your essay should be at least 300 words long and demonstrate your ability to express ideas clearly, use proper grammar, punctuation, and spelling. Remember to include an introduction, body paragraphs with supporting details, and a conclusion.Topic:The Importance of Books in Our LivesBooks have been a source of knowledge, entertainment, and inspiration throughout history. Write an essay discussing why books are important in our lives. Support your argument with examples from your own experience or from literature.Marking Scheme:•Introduction and thesis statement (5 points)•Body paragraphs with clear arguments and examples (15 points)•Conclusion and coherence (5 points)•Grammar, punctuation, and spelling (5 points)Example Essay:Title: The Indispensable Role of Books in Our LivesIntroductionIn today’s digital age, where information is readily accessible through various electronic devices, the significance of books may seem diminished to some. However, the importance of books in our lives cannot be overstated. They serve as a bridge between the past and present, a source of knowledge, a medium for entertainment, and a catalyst for personal growth.Body ParagraphsArgument 1: Knowledge and EducationBooks are a treasure trove of knowledge. They provide us with insights into different cultures, historical events, scientific discoveries, and philosophical ideas. Reading books broadens our horizons and allows us to learn about the world beyond our immediate environment. For instance, reading “A Brief History of Time” by Stephen Hawking hashelped me understand complex concepts of physics and cosmology in a way that textbooks alone couldn’t achieve.Argument 2: Entertainment and ImaginationBooks offer a form of escapism and entertainment. They allow us to travel to distant lands, meet fascinating characters, and experience adventures we might not encounter in real life. “The Lord of the Rings” trilogy by J.R.R. Tolkien, for example, transported me to Middle-earth, immersing me in a world filled with hobbits, elves, and epic battles. Such books stimulate our imagination and creativity, which are essential skills for problem-solving and innovation.Argument 3: Emotional Development and EmpathyReading books can also enhance our emotional intelligence and empathy. Through literature, we can gain insight into the human condition and understand the feelings and perspectives of others. “To Kill a Mockingbird” by Harper Lee taught me about racial injustice and the courage to stand up for what is right, even when it is unpopular.Conclusion。

背阳光的猫艾儿坐在草地上,享受着温暖的阳光。
突然,一只灰猫在附近的一座草房和不远处的一棵枯树之间穿梭……“小猫,你在忙什么?”艾儿好奇地问。
“我在背阳光呢!小姑娘有兴趣不妨进屋坐坐。
”小猫说。
艾儿跟着小猫进了屋。
忽然,艾儿听到一阵呻吟。
“那是个奄奄一息的老太婆。
”猫说。
艾儿走到床边,问:“老婆婆,你哪儿不舒服呀?”“这屋里冷呀!可把我这把病骨头冻坏了!”艾儿搀住老婆婆的手,想扶她走出屋子。
“不行呀!”老婆婆说,“在床上躺了太久,动不了了。
唉——”怎样才能帮助老婆婆呢?艾儿突然眼睛一亮,向灰猫恳求道:“请你给老婆婆背点儿阳光吧!”“哼!”灰猫傲慢地说,“我只给自己背。
不过,如果你愿意做一只猫,这事还能商量商量。
”“永远都变作一只吗?”“也许。
”“嗯,那好吧,其实当一只背阳光的猫也不坏呀!”艾儿话音未落,浑身就被一团金光笼罩了,身体渐渐缩小,最后变成了一只小白猫。
灰猫把艾儿带到枯树下,说:“只有这儿的阳光能背,你上树吧!”艾儿爬上了树,在树枝上静静地蹲着,果然,她觉得背上越来越重。
当爬进屋子时,她发现自己通体金光。
然后她把阳光往床上轻轻一抖,老婆婆双眼顿时有了光泽,高兴得喊道:“阳光!阳光!”艾儿听了,更卖力地背着阳光。
阳光洒落在地板上,洒落在桌子上,洒落在老婆婆布满皱纹的脸上,屋子里变得亮堂堂的,老婆婆也变得精神矍铄。
艾儿觉得开心极了,但她实在太累了,便一头扎在桌子底下,甜甜地睡着了……1.读文中画横线的句子,回答问题。
“老婆婆也变得精神矍铄”,此时还可以用、等成语来形容。
2.艾儿跟着小猫进屋后,她发现了什么?她为什么要帮助老婆婆?3.在文中找出描写艾儿为老婆婆背阳光的动作的词语。

四年级数学上册暑假预习与检测衔接讲义第五章平行四边形和梯形【知识点归纳】一、平行与垂直1、同一平面内的两条直线的位置关系,不是平行就是相交。
2、在同一平面内不相交的两条直线叫做平行线,也可以说这两条直线互相平行。
图一:“直线A和直线B是平行线;直线A 和直线B互相平行。
〞3、平行可以用符号“//〞表示。
a与b互相平行,记作a//b,读作:a平行于b。
4、如果两条直线相交成直角,就说这两条直线互相垂直,其中一条直线叫做另一条直线的垂线,这两条直线的交点叫做垂足。
图二:“直线A和直线B相互垂直;直线A是直线B的垂线;点C是垂足。
〞5、垂直可以用符号“⊥〞表示。
a与b互相垂直,记作a⊥b,读作:a垂直于b。
6、两条直线互相垂直,可以组成4个直角。
有1个垂足。
7、从直线外一点到这条直线所画的垂直线段最短,它的长度叫做这点到直线的距离。
垂直的线段最短。
9、两条平行线之间可以画无数条垂直线段,这些垂直线段不仅互相平行而且长度相等。
平行线间的垂直线段都相等。
10、过直线上一点和直线外一点画直线的垂线,只可以画1条。
过直线外一点画直线的平行线只可以画1条。
二、画垂线的方法1、过直线上一点画这条直线的垂线:2、过直线外一点画这条直线的垂线:3、从直线外一点到这条直线所画的垂直线段最短,它的长度叫做这点到直线的距离。
垂直的线段最短。
即“点A到直线所画的垂直线段最短;点A到这条直线的距离是10厘米〞三、画平行线的方法1、可以用直尺和三角尺来画平行线,先把三角尺的一条直角边紧靠直线,再把直尺紧靠三角尺的另一条直角边,这时沿直尺平移三角尺,再画一条直线就可以了。
2、平行线间的垂直线段最短3、画出一条长3厘米,宽2厘米的长方形先画一条长3厘米的线段;再过线段端点画一条2厘米的垂线;再过另一个点也画一条2厘米的垂线;连接两个端点就可以了。
四、平行四边形1、两组对边分别平行的四边形,叫做平行四边形。
2、平行四边形的两组对边不仅平行而且长度相等。

所以,这个数 = 9 × 107 + 5 = 968。
2、题目:一个数除以8,商是104,余数是6,这个数是多少?A. 832B. 838C. 842答案:B解析:根据除法的定义,被除数 = 除数 × 商 + 余数。
所以,这个数 = 8 × 104 + 6 = 838。
3、题目:一个数除以5,商是123,余数是4,这个数是多少?A. 615B. 619C. 620答案:B解析:根据除法的定义,被除数 = 除数 × 商 + 余数。
所以,这个数 = 5 × 123 + 4 = 619。
4、题目:一个数除以6,商是102,余数是2,这个数是多少?A. 610B. 612C. 614答案:B解析:根据除法的定义,被除数 = 除数 × 商 + 余数。
所以,这个数 = 6 × 102 + 2 = 612。
5、题目:一个数除以7,商是105,余数是3,这个数是多少?A. 735B. 738C. 740答案:B解析:根据除法的定义,被除数 = 除数 × 商 + 余数。
所以,这个数 = 7 × 105 + 3 = 738。
二、多选题(每题4分)1.下面哪些数既是2的倍数,又是5的倍数?(多选)A. 10B. 15C. 20D. 25答案:A、C解析:2的倍数特征是个位数字是0、2、4、6、8,5的倍数特征是个位数字是0或5。
因此,既是2的倍数又是5的倍数的数,其个位数字只能是0。
二年级上学期数学学科预习建议温馨提示:预习过程中若遇有不懂的问题,是非常正常的现象,不要责备孩子,可在网上给老师留言,老师会及时耐心地解答每位学生的问题。
第一周预习计划1.内容:第二单元 100以内的加法和减法2.主要教学目标:本周的学习内容是让学生会用竖式计算100以内的加法和减法,其中进位加和退位减是本单元的重点,进位加容易出现进到十位的一忘记加上,退位减容易出现当十位被个位退一之后就少了一个十,在十位相减时容易忘记。
所以请家长在教孩子预习时,要着重注意这两点,当孩子出现错题时,不要盲目改错或说教,要让孩子自己先找出错误的地方,说一说错在哪了,再改错。
同时,本单元的内容也需要多加练习。
星期一:请家长领着学生预习数学书p11---13页的不进位加法。
这节课内容主要让学生知道两位数加一位数和两位数加两位数的不进位加法除了可以用摆小棒、口算的方法计算外,还可以用竖式计算,也就是笔算。
在计算的过程中,要注意:1.个位加个位,十位加十位。
(个位对齐个位,十位对齐十位;也就是相同数位要对齐。
)2.从个位算起。
这节课的重点要注意:规范书写(为了便于规范书写,在写竖式的时候要注意将个位上的数和十位上的数空开一个数字的距离,这样才能更好的使数位对齐。
加号写在第二个加数的前面。
横线要求用直尺。
计算的结果也要求数位对齐。
)作业:(1)书上p12、13页的做一做。
(书写要求工整、规范)(2)口算p1、2页。
(学生做完后,请家长帮助检查。
)星期二:请家长领着学生预习数学书p14页的进位加法。
(笔算进位加法)这节课内容主要让学生知道,在计算进位加法时,个位相加满十要向十位进1。
先通过摆小棒的方法来解决问题,让学生了解满10根小棒就要捆成1捆,也就是在竖式计算中个位相加满十向十位进1。
在计算的过程中,要注意:1.相同数位相加。
(相同数位要对齐。
)2.从个位算起。
3.个位相加满十,向十位进1。
书写竖式的时候,注意:进位的1要写的小一点,横线要用直尺。

(认识比)
知识预览
1.比的基本性质:
比的前项和后项同时乘以或除以相同的数(0除外)比值不变。
a:b=(am ):(bm )=(a ÷m ):(b ÷m )(b ≠0, m ≠0 )
两个数的比表示两个数相除,比的前项和后项相除所得的商叫做比值 例如:5:3=(5*3):(3*3)=15:9 15:9=5:3
5是比的前项3是比的后向 同时乘或除以相同的数(0除外),比值不变。
(1)小数比化成最简整数比:方法如下:
先把小数化成整数,然后除以前项与后项的最大公因数。
(2)分数化成最简整数比:方法如下: 两个分数的分母乘以两个分母的最小公倍数,如果不是最简整数比 按照基本的法则进行化简。
