Maybe those who don’t like getting up early will not believe this, but it is true. Scientists made a survey(调查) in about one thousand people, and then they found that early rising people had less disease(疾病) than late rising people, and early rising people also look healthier than late rising people, and so on.So we may know early rising is helpful in more than one way. Firstly, it helps to keep us healthy. We all need fresh(新鲜的) air. And air is the freshest early in the morning. Besides(此外), it is useful to do morning exercises.Secondly, early rising helps us in our studies. In the morning we learn more quickly and find it easier to understand what we learn.Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan.Fourthly, early rising gives us enough time to get ready for our work, such as to wash our hands and faces and eat our breakfast.Late risers may find it difficult to form(形成) the habit(习惯) of early rising. They have to make an effort(努力) to do so. As the English proverb(谚语) says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”( )26. We may read this passage in a ____________ magazine.A. healthB. sportsC. musicD. travel( )27. Early rising people are ____________ than late rising people.A. fatterB. thinnerC. healthierD. cleverer ( )28.

I know that he was a kind and gentle (温柔的) man at heart, because when I was young, he gave me presents, and sat me on his knees, and told me stories. But I believe the boys at his school were afraid of him.At school, when he walked into a room full of noisy boys, there was silence at once. When he looked at a boy with a certain look in his eyes, that boy went red in the face, and looked down at his shoes. If a boy brought him poor, careless work, the work that was not the best that boy could do, my grandfather picked up the boy's book and threw it across the room, shouting, "Do it all again, and bring it back first thing in the morning!" If the boy was late, or if he forgot to bring the work, he had to do it again, and again, and yet again. My grandfather never forgot. He was a very different man at school, from the man I saw day by day in his own home.( )36.

One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .41. When he was in China , Marco polo ___________ .A. discovered CaiLun invented paperB. learned to make paperC. saw many wonderful thingsD. told people about it42.

My name is Alice. I am 12 years old. I live in New York City with my parents. I am a student at Lincoln Elementary School. My favorite subject is English because I love reading and writing. I also enjoy playing the piano. I have been learning it since I was six years old.After school, I usually go to the English enhancement class. It is a special class that helps students improve their English skills. In this class, we learn new vocabulary, practice reading, and work on grammar exercises. Our teacher, Mr. Brown, is very patient and explains everything clearly. He always encourages us to ask questions and participate actively in the class.One of the activities I enjoy the most is the weekly book club. We choose a book to read together as a group and then have discussions about it. This helps to improve our reading comprehension and allows us to share our thoughts about the story. Each member of the book club takes turns leading the discussion, which enhances our public speaking skills.In addition to the English enhancement class, I also attend the math Olympiad class. The class is more challenging, but I find it very interesting. We solve complex mathematical problems and learn new problem-solving strategies. Our teacher, Miss Johnson, always provides us with useful tips and tricks to solve difficult questions. It has greatly improved my analytical thinking and logical reasoning abilities.Overall, I am grateful to have the opportunity to be a part of the English enhancement and math Olympiad classes. They have not only expanded my knowledge but also helped me develop essential skills. I believe that with these extra classes, I will be well-prepared for the challenges that lie ahead.Questions:1.

2018-2019学年六上浙教版期末测试数学试卷复习强化提优数学数学试卷含解析

2018-2019学年六上浙教版期末测试数学试卷复习强化提优数学数学试卷一、填空题1．王老师要焊接一个长方体框架，可使用的材料如下。

为了方便起见，在不对铁条进行切割的前提下，王老师可做的这个长方体模型长、宽、高分别是________厘米，________厘米和________厘米；如果在这个长方体外面糊上一层包装纸，在里面最多可以放________个棱长为3厘米的小正方体木块。

【答案】25 20 9 144【分析】首先根据长方体有12条棱，4条长，4条宽，4条高，以及可使用的铁条材料，可得张老师可做的这个长方体模型长、宽、高分别是25厘米、20厘米和9厘米；然后分别用长方体的长、宽、高除以正方体的棱长，求出它们分别包含多少个棱长，再把它们相乘，求出在里面最多可以放多少个棱长3厘米的小正方体木块即可。

【详解】由分析可知张老师可做的这个长方体模型长、宽、高分别是25厘米、20厘米和9厘米。

因为2538÷=……1，2036÷=……2，933÷=，所以在长方体里面最多可以放棱长3厘米的小正方体木块的数量是：863144⨯⨯=（个）。

【点睛】认真分析题意，熟练掌握长方体和正方体的特征，根据实际解答。

2．王叔叔的小汽车行驶52千米用了524升汽油。

平均每千米需要用汽油（________），平均每升汽油可行驶（________）千米的路。

【答案】11212 【分析】因为每份数×份数＝总量，所以先把524升汽油看作总量，52千米看作份数，求每份数就得用总量÷份数，则列式为：524÷52，求的是平均每千米需要用汽油多少升；则另一个问题就是把路程看作总量，所用汽油看作份数，求每份数就得用52÷524，表示的是“平均每升汽油可行驶多少千米的路程”。

【详解】524÷52＝112（升） 52÷524＝12（千米）【点睛】两个问题互相关联且难以区别，如果利用总量、份数、每份数三者之间的关系，能够顺利理清每一次问题的核心，从而降低难度，顺利解答。
