人教版英语九年级unit10知识点总结Unit 10 Knowledge Points Summary - A Comprehensive Guide to Mastering EnglishIntroductionEnglish is a universal language that opens up numerous opportunities for communication, education, and career advancement. In unit 10 of the 9th-grade English course, several essential knowledge points are covered. This article aims to provide a comprehensive summary of these points and offer valuable insights to help students master English effectively.1. VocabularyVocabulary acquisition plays a crucial role in language learning. In unit 10, students encounter a variety of vocabulary words related to environment and pollution. To enhance their vocabulary skills, it is beneficial to adopt different strategies, such as reading extensively, using flashcards, and engaging in regular practice exercises. By incorporating new words into daily conversations or writing exercises, students can reinforce their understanding and retention.2. GrammarGrammar is the backbone of any language, including English. In unit 10, students focus on several essential grammar points. Firstly, they learn about the Passive Voice, which is used when the subject of the sentence is acted upon, rather than acting. Understanding the passive voice is essential for effective communication and diverse writing styles.Additionally, students delve into the usage of Modal Verbs, which express ability, possibility, necessity, or permission. Practicing modal verbs in different contexts can significantly improve students' language accuracy and fluency. It is also crucial to grasp the differences between similar modal verbs, such as 'can' and 'could', as well as 'may' and'might'.3. Reading ComprehensionEnhancing reading comprehension skills is vital for understanding complex texts and broadening one's knowledge. Unit 10 introduces students to a variety of reading passages related to environmental issues and conservation efforts. To improve reading comprehension, it is beneficial to scan the text beforehand for contextual clues, skimming for the main idea, and reading actively by underlining or highlighting key points. Students can also practice summarizing the texts to ensure a deeper understanding of the content.4. Listening SkillsListening is an integral part of effective communication. Unit 10 provides listening exercises centered around environmental concerns, such as global warming and deforestation. To enhance listening skills, it is essential to expose oneself to different types of audio resources, including podcasts, songs, and videos. Practicing listening comprehension regularly helps students develop their ability to identify key information, infer meaning from context, and recognize different accents and speech patterns.5. Speaking PracticeUnit 10 encourages students to engage in discussions related to environmental issues. This provides an excellent opportunity for students to express their opinions, debate varying viewpoints, and develop critical thinking skills. To improve speaking proficiency, it is beneficial to participate actively in classroom discussions, join speaking clubs or language exchange programs, and practice pronunciation and intonation patterns regularly.6. Writing SkillsWriting is an essential skill that enables effective expression and communication. In unit 10, students are encouraged to writeargumentative essays or persuasive speeches concerning environmental protection. To improve writing skills, it is crucial to develop a clear thesis statement, organize ideas logically, and provide supporting evidence. Students should also focus on enhancing their vocabulary usage, grammar accuracy, and overall coherence and cohesion in their writing.ConclusionUnit 10 of the 9th-grade English course covers significant knowledge points that are essential to mastering English. It is vital for students to develop vocabulary skills, grasp important grammar concepts, enhance reading and listening comprehension, improve speaking proficiency, and refine writing abilities. By dedicating time and effort to these areas, students will significantly enhance their English language proficiency and open doors to endless opportunities in their personal and professional lives.。

学位英语图文总结12-Unit 10-Ode to Public Transport
Unit 10-Ode to Public TransportText APre-reading Question1.Do you find it important to use public transportation? What are some of the reasons?2.What suggestions do you give to others on using public transportation?1.According to the author, public transportation is ____.A.a service which is available for use by the general publicB.not a cheaper and environmentally friendly alternativeC.a transportation service that you can arrange privatelyD.a transportation service that suits your personal convenience2.The author knew the importance of public transportation through ____.A.news reportsB.first-hand experienceC.a US Congressman's speechD.research done in America3.Which of the following is NOT a reason for riding public transportation?A.It helps the environment.B.It saves money.C.It provides ease and convenience.D.It saves time.4.Public transportation provides valuable service to ____.A.local residents in the area onlyB.everyone in the areaC.tourists to that area onlyD.both local inhabitants and tourists5.The author's attitude toward public transportation is _____.A.neutralB.negativeC.positiveD.objectiveThe Importance of Public TransportationA US Congressman once proclaimed that, "There can be no doubt that the transportation sector is the most critical sector of our economy." I know exactly what he means. In this day and age, access to transportation is considered a necessity.1.no doubt that 毋庸置疑2.critical 至关重要的=crucial3.access to 获得…的渠道、机会、权利4.necessity 必需品= necessaryPublic transportation is defined as a service that is available for use by the general public. It is a cheaper and environmentally friendly alternative. It is not a transportation service that you can arrange privately to suit your own personal convenience (although you may, to a certain extent, such as paying for a cabin or suite on a train or ship). since you have to consider other passengers who are riding and making similar arrangements with you.5.alternative 替代品= substitute6.cabin 小木屋、舱房suite 套房I have experienced first-hand how important public transportation is .I live in Saipan, a US territory and the closest things we have to public transportation are tourist and school buses. You have to have your own car or bike, rent a car, or pay upfront for a taxi to go from point A to point B. Otherwise you end up basked in sweat and sunburn traveling to work every day. When I first came here, I walked. I walked going to and from work.7.pay upfront for 预付(upfront 预先支付的)8.end up 结果是9.bask 晒太阳sweat 汗水、流汗sunburn 晒伤I walked to the store and lugged my heavy groceries back to the house. I walked to church and I barely got to go to places farther than a twenty-mile radius from my house. since I did not own a car then, and I considered renting a car and riding a taxi such an expense for a starting single mother like I was at that time.For me, public transportation is very important because of the following reasons :10.Lug 吃力地拖、拉、拽11.grocery 杂货店、杂货12.radius 半径(diameter 直径/ meter 米)1.It saves money.According to research done by the American Public Transportation Association,individuals can save up to $9,515 annually by parking their cars at home and using public transportation instead. In this economy, saving money has become a main concern in most households. With the rising prices of fuel and other vehicle-related expenses, doing the public commute to work and school certainly saves money.13.done by= conducted by14.up to 至多15.household 家庭16.fuel (n.)燃料(v.)加强(strengthen)、刺激(stimulate)2.It helps the environment.When you switch from driving your car to taking public transport, you are reducing your carbon footprint and making a great step forward in saving the environment. The environmental costs of individuals using their cars every day has done massive damage to the environment and if the majority or all individuals like you and me use public transport instead, think of what good we could do for the environment.17.switch 转变= shift开关按钮switch from A to B :从A转变到B18.carbon footprint 碳足迹(emission)3.It will wean us out of energy dependence.According to a paper made by Dr. Jean-Paul Rodrigue and Dr. Claude Comtois, transportation accounts for approximately 25% of world energy demand and for more than 62% of all the oil used each year. Ninety-five percent of transportation is almost completely reliant upon petroleum products with the exception of railways using electrical power.19.wean 断奶- 逐渐减少wean sb out of sth 使某人逐渐摆脱sth20.account for 占...比重21.reliant upon= depend on 依赖依靠22.petroleum 石油23.with the exception of 除…之外(exception例外/ expection 期望、预期)While the use of petroleum for other economic sectors, such as industrial and electricity generation, has remained relatively stable, the growth in oil demand is mainly attributed to the growth in transportation demand.When we strengthen our public transportation services, we are consequently lessening this oil demand and dependence. It will also motivate us to consider alternative energy and fuel resources.24.attribute to 归因于、由于25.lessen 减少(reduce)26.motivate 激励、动员4.It provides ease and convenience.Having public transportation definitely eases some of the burdens of people who do not have cars or prefer not to own one. They are provided with choices to use public transport. Public transportation also provides valuable services not just to local inhabitants in the area but to tourists as well. When a tourist visits a place, which does not have public transportation, their choices are limited and the experience they get is limited, too.27.inhabitant= dweller 居民inhabit 居住、栖息inherit 继承All in all , public transportation improves our way of life, strengthens the community, provides new jobs for the public and gives us a cleaner environment.1.According to the author, public transportation is ____.A.a service which is available for use by the general publicB.not a cheaper and environmentally friendly alternativeC.a transportation service that you can arrange privatelyD.a transportation service that suits your personal convenience网校答案:A (第二段第一句)2.The author knew the importance of public transportation through ____.A.news reportsB.first-hand experienceC.a US Congressman's speechD.research done in America网校答案:B (第三段)3.Which of the following is NOT a reason for riding public transportation?A.It helps the environment.B.It saves money.C.It provides ease and convenience.D.It saves time.网校答案:D (看四个小标题)4.Public transportation provides valuable service to ____.A.local residents in the area onlyB.everyone in the areaC.tourists to that area onlyD.both local inhabitants and tourists网校答案:D (倒数第二段第三行)5.The author's attitude toward public transportation is _____.A.neutralB.negativeC.positiveD.objective网校答案:C (尾段结论,优点。
