Welcome to the Club! and answer the questions that follow.I came here to teach English in my early 20s and eventually moved into business, running a small import-export operation. I majored in Mandarin Chinese back in the U.S. and continued my languag e studies here. I’m now fluent in Chinese and my reading is just about perfect, I’m married to a local woman and have three kids who were all born and raised here. Granted, I haven’t got Chinese citizenship, as that would have involved me renouncing my Ame rican citizenship. I wasn’t prepared to do that as it would have caused me too many headaches, not least of which would have been having to get a visa every time I wanted to go back to visit family. But I have permanent residency in China and consider this my home. Despite all this, most Chinese people will always see me as an outsider. When I speak Mandarin, some people sometimes stare at me like I’m from another planet as they just can’t get it into their heads that a foreigner can speak their language. Also, as an African-American and a fairly tall guy, I am constantly stereotyped. People will ask if I can play basketball and are incredulous when I say I’m not a big fan. Once when I had just come through customs, I was mobbed by a huge group of fans who were waiting to greet some NBA stars who were visiting. It took me ages to explain that they had the wrong guy. Most of the stereotypes people have here are pretty harmless and there is no malice intended, but it can be pretty annoying, especially when peop le act amazed on discovering you’re a businessman.43. Which of the following is true about the writer?a. He has Chinese citizenship.b. He enjoys basketball.c. He has spent many years in his adopted country.d. He has had no issues adapting in his adopted country.44. What do people find hard to believe about the writer?a. He is an NBA star.b. He is an American businessman.c. He has so many children.d. He speaks Mandarin fluently.45. Why did fans mistake the writer for someone famous?a. He is black.b. He is tall.c. He looks American.d. All of the above.46. The word malice is closest in meaning to which of the following?a. harmb. visac. residencyd. stereotype(B)Directions:Directions: Read the following excerpt from Smarty Pants: The Stars with Big Brains and answer the questions that follow.Conan O’BrienThere’s no doubt that the late-night talk show host has the gift of the gab. He’s known for poking fun at anyone and everyone in the entertainment industry including himself. Illustrative of his knack for irreverent, quirky humor is the fact that he was a writer and producer for The Simpsons for a couple of seasons before he made a name for himself. Some might feel that his brand of humor is far from intellectual. However, there is no disputing the 50-year-old’s academic credentials. He graduated magna cum laude from Harvard with a degree in history in 1985.Natalie PortmanThe Israeli-born actress is the perfect example of how beauty and brains need not be mutually exclusive. In addition to starring in many critically acclaimed films, she is known for her political-activism, supporting causes like same-sex marriage in the U.S. and women’s rights in developing countries. Although she made her big screen debut in 1994 at the tender age of 12, she did not let it affect her education. Like O’Brien, Portman attended Harvard, where she got her bachelor’s degree in psychology in 2003 while continuing her work as an actress. Furthermore, Portman is also a polyglot, with fluency in Hebrew, French and Japanese.47. What did Conan O’Brien do before he was famous?a. studyb. drawc. actd. sell48. According to the excerpt, what do Portman and O’Brien have in common?a. They are 50 years old.b. They graduated in the same year.c. They majored in the same subject.d. They studied at the same university.49. Where is Portman originally from?a. Franceb. Japanc. the Middle Eastd. the U.S.50. The word polyglot is closest in meaning, as it is used in the excerpt, to which of the following?a. bilingualb. multilingualc. Jewishd. deaf。

2020年期末考试八年级上册英语作文
2020年期末考试八年级上册英语作文全文共6篇示例，供读者参考篇1My 2020 Final ExamsWow, what a crazy year 2020 has been! I can't believe I just finished taking my final exams for 8th grade English, math, science and other subjects. This school year will definitely be one to remember, that's for sure.I've been going to Oakwood Middle School for the past three years, and mrs. Johnson has been my English teacher since 6th grade. She's a pretty cool teacher - makes learning grammar and writing essays kind of fun actually. Normally she makes us do lots of practice essays and writing assignments to get ready for the big English final exam at the end of the year. But this year with COVID-19 and everything, so much was different.We ended up having to do remote learning starting in March after the lockdowns began. At first it was kind of exciting getting to stay home and learn from my laptop. But after a few weeks, it started to feel really hard and lonely not being able to see my friends or teachers in person. We had to have all our classes overvideo chat, which was just really awkward and glitchy a lot of the time. Trying to learn new grammar concepts or get help revising an essay just wasn't the same.I remember feeling really stressed out when Mrs. Johnson told us we'd still have to take the big English final exam, but it would be online instead of in-person at school. I've never been a great test taker, and the thought of having to write a whole essay on the computer for a timed exam made me super nervous. There were a lot of tech issues too - people's wifi cutting out, not being able to hear the instructions clearly, that kind of thing. Such a mess!But I tried to stay positive and studied really hard leading up to the exam. My mom helped me do practice writing prompts timed on the computer to get me ready. I made sure to get a good night's sleep and eat a good breakfast before the big day. When the time came, I just did my best to block out any distractions around the house and focus.The exam ended up having two main parts - some multiple choice questions testing our grammar and reading comprehension skills first. That part wasn't too bad. But then we had to write a whole descriptive essay about a person or place that was really important to us. We only had 60 minutes tobrainstorm our ideas, make an outline, and actually write the full 5 paragraph essay. My hands were shaking a little as the countdown timer started!I decided to write my essay about my grandpa, who is one of the most special people in my life. I covered how he grew up on a farm, went off to serve in the military, started his own business, and has so many wise sayings and great life lessons to share. Describing his warm personality, his cowboy boots and plaid shirts, the affectionate nickname "Pops" our whole family calls him. Making sure to include a clear thesis statement, relevant details and examples in each body paragraph, and a strong conclusion. Proofreading and fixing any errors I spotted as best I could with the limited time.When the timer went off signaling the end, I have to admit I felt a huge sense of relief just to have that intense pressure of the exam over with. Of course then the waiting and wondering how I did began! A few weeks later, once all the essays had been graded, we got our scores back from Mrs. Johnson. I was over the moon to find out I got an A- on the exam! All that hard work and perseverance paid off. She said my descriptive essay was full of rich details and really让her feel like she knew my grandfatherpersonally. I was proud that my writing skills had improved so much over the school year.Looking back, while taking an important exam from home online definitely had its challenges, it also helped me build resilience, time management, and tech skills that will be useful in the future. The 2020 final exams won't be something I'll forget anytime soon, that's for sure! I'm just glad to have all my 8th grade courses behind me now as I get ready to start high school in the fall. Bring on the next chapter!篇22020 End of Year Exams – An Eighth Grader's PerspectiveWhew, what a year 2020 has been! I can't believe I'm already wrapping up 8th grade and getting ready for my final exams. This school year has definitely been the craziest and most challenging one of my life so far.It all started back in March when COVID-19 really started spreading across the country. One day we were going to school like normal, and the next thing we knew, everything was shutting down due to the pandemic. My friends and I were honestly pretty excited at first when we found out school would be closedfor a couple of weeks. A surprise extended spring break? Yes, please! Little did we know that it would end up being much more篇3Final Exams in the Crazy Year of 2020Wow, what a year 2020 has been! I'm an 8th grader and I just finished my final exams for the first semester. But these exams were like nothing I've ever experienced before because of the coronavirus pandemic that turned everything upside down.It all started back in March when our school closed down due to COVID-19 spreading across the country. One day we were Going to classes like normal, and the next thing we knew, we were told school would be closed for at least a few weeks. At first, I was excited for an unexpected extended spring break! No school = no homework or tests for a little while. Sounds awesome, right?Well, the vacation didn't last long. Within a week, our teachers had figured out how to use video conferencing apps like Zoom and Google Meet to have virtual classes online. So there we were, sitting at home in our pajamas, trying to learn algebra and biology from our laptop screens. It was so weird! The internet kept cutting out, my little brother was runningaround yelling in the background, and the cat wouldn't stop jumping on the keyboard. What a mess.But we had to make it work, because those few weeks of online classes turned into months as the coronavirus situation kept getting worse. By the end of the school year, it was clear we wouldn't be going back to in-person learning. We had our final exams for the 2019-2020 school year virtually too. Instead of sitting at desks in the classroom, we logged into a portal and took the tests on our computers at home. Honestly, it was kind of nice being able to take exams in my comfy pajamas without stress. But it was also really tough because we had no teacher there to ask questions if we got stuck or confused.Somehow we all made it through that crazy spring semester, and then we had an entire summer of uncertainty about what the next school year would look like. When we finally went back in August 2020 for 8th grade, it was a total hybrid model - some days we were in school, some days online. And everything was so different with all the COVID safety protocols in place. We had to wear masks all day, couldn't share supplies, and were spaced really far apart with plastic dividers on our desks. No group activities, no assemblies, no cafeteria...it was all just strange and somber.But hey, we were just happy to have some sense of normalcy and routine back in our lives, even if it was a "new normal." School became our escape from being cooped up at home and a break from watching the scary news about the pandemic. We learned to adapt and be resilient.Now here I am finishing up my first semester of 8th grade, which has been filled with its own challenges thanks to the COVID crisis. These final exams were definitely not normal either. For the in-person days, we had to take our exams spread out in the gym instead of in classrooms to allow for more social distancing. The desks were separated by 6 feet, we had face masks on the whole time, and we couldn't ask the teachers questions if we got stuck. The rules for the virtual exam days were strict too - we had to keep our cameras on, couldn't look away from the screen, and show our workspace to prove we didn't have any notes or resources out.It was a super stressful few weeks of studying and testing, but we powered through. As difficult as this semester has been with the hybrid learning model, I'm just proud of myself and my classmates for persevering and doing our best despite all the obstacles and weirdness. Nothing about 2020 has been ideal, but we're getting through it day by day.Now I've got a nice long winter break ahead to relax, recharge, and get ready for the second semester of 8th grade. Who knows what else 2021 has in store for us? I'm really hoping we can go back to normal in-person school soon. But after making it through this crazy year, I know I can handle anything thrown my way. Eighth grade in 2020 has taught me to be flexible, resilient, and not take normal life for granted. Even though it was hard, I've gained perseverance and grit. I'm becoming way more responsible with my schoolwork too since we don't have teachers constantly looking over our shoulders in virtual learning.So here's to making it through 2020 and becoming a stronger person! I've learned that I can push through and overcome major challenges and obstacles. If I can pass final exams during a global pandemic with a hybrid school model, I'm confident I can achieve anything I set my mind to. Eighth grade in 2020 has been one crazy ride, but I've made it to the finish line. Bring on 2021!篇4Certainly, here is a 2000-word essay written in the voice of an eighth-grade student, with the topic "2020 Year-End Exam, Grade 8, First Semester English Composition":My 2020 Year-End Exam ExperienceWhew, what a crazy year 2020 has been! I never imagined that my final year of middle school would be so full of surprises and challenges. From the COVID-19 pandemic disrupting our normal school routine to having to adapt to online classes, it's been a roller coaster ride for sure. But through it all, I've learned so much, and I'm grateful for the opportunity to share my experience with this year-end English exam.Let me start by saying that preparing for this exam was no walk in the park. With all the disruptions and changes we faced, it was hard to stay focused and motivated. I'll admit, there were times when I felt like giving up, especially during those long stretches of online classes where it seemed like the material was just going in one ear and out the other.But then I remembered how important this exam was for my future. A good score could open doors to some of the best high schools in the area, and that was something I really wanted. So, I buckled down and got serious about my studies.One of the biggest challenges was trying to learn English without the face-to-face interaction with my teacher and classmates. Don't get me wrong, our online classes were great, and our teacher did an amazing job trying to keep us engagedand on track. But there's just something about being in a physical classroom that makes it easier to stay focused and ask questions when you're struggling.To overcome this, I had to get creative. I started setting up virtual study sessions with a few of my friends, where we could practice our English conversation skills and quiz each other on grammar and vocabulary. We even had a friendly competition going to see who could improve the most by the end of the semester.Another thing that really helped me was finding ways to immerse myself in the English language outside of class. I started watching movies and TV shows in English (with subtitles, of course), and I even tried reading some of my favorite books in their original English versions. It was tough at first, but the more I exposed myself to the language, the more comfortable and confident I became.Speaking of confidence, I have to give a shout-out to my parents for their unwavering support and encouragement throughout this whole process. Whenever I felt like I was hitting a wall or doubting myself, they were there to remind me of how far I'd come and how capable I was of achieving my goals.As the exam date approached, I'll admit, I was a bundle of nerves. But all the hard work and preparation paid off in the end. When I walked into that exam room, I felt ready. Sure, there were a few questions that threw me for a loop, but I just took a deep breath and did my best to apply everything I'd learned.And you know what? It wasn't as bad as I thought it would be! I actually found myself enjoying the challenge and feeling proud of how much I'd grown in my English skills over the past year.Looking back on this experience, I've learned so much more than just English grammar and vocabulary. I've learned about perseverance, resilience, and the importance of having a strong support system. I've also gained a deeper appreciation for the English language and the countless opportunities it can open up for me in the future.To my fellow eighth-graders who are also facing this exam, I want to leave you with a few pieces of advice:Don't be afraid to ask for help when you need it. Your teachers and classmates are there to support you, so don't be shy about reaching out.Find ways to make learning fun and engaging. Whether it's watching movies, listening to music, or playing educational games, the more you can immerse yourself in the language, the better.Believe in yourself! You've made it this far, and that's something to be proud of. Trust in your abilities and knowledge, and don't let self-doubt hold you back.Remember that this exam is just one step in a much longer journey. No matter what the outcome, there will be plenty of other opportunities to grow and succeed.So, here's to all of us eighth-graders, navigating the ups and downs of this crazy year and coming out stronger on the other side. We've got this!篇5My Final Exams for 8th Grade EnglishIt was that dreaded time of year again – final exams! I couldn't believe we were already at the end of the first semester of 8th grade. Time had flown by so quickly. As I looked over my exam schedule, I felt a mix of emotions – nervousness, excitement, and even a little bit of confidence.English was one of the exams I was most anxious about. It's not that I didn't like the subject or wasn't good at it, but there was just so much material to cover. From grammar rules and vocabulary to reading comprehension and writing essays, the exam would test our skills in all areas of the English language.My English teacher, Mrs. Thompson, had been preparing us for weeks. She kept reminding us that the final exam wasn't just about memorizing facts and rules, but also about applying what we had learned throughout the semester. "The exam will challenge you to think critically and express yourselves clearly," she would say with a smile that was both encouraging and slightly mischievous.One of the things I found most challenging in English was the writing component. Essays and short stories always seemed so daunting to me. How was I supposed to come up with an interesting plot, develop compelling characters, and use descriptive language all at the same time? Mrs. Thompson tried to make it easier by giving us prompts and guidelines, but I still felt overwhelmed sometimes.As the exam date approached, our class spent a lot of time reviewing key concepts and practicing sample questions. We went over the different types of essays we might be asked towrite, like persuasive essays, narrative essays, and expository essays. We also reviewed the importance of using proper grammar, varied sentence structures, and strong vocabulary.During one of our review sessions, Mrs. Thompson reminded us of the importance of reading the prompts carefully and planning our essays before diving into the writing. "Awell-structured essay with a clear thesis statement and supporting details will go a long way," she advised.I also remember her emphasizing the need to proofread our work thoroughly. "One silly mistake in grammar or spelling can detract from an otherwise excellent essay," she cautioned.As the exam day approached, I felt a mix of nervousness and determination. I knew I had worked hard all semester, and I was as prepared as I could be. When the day finally arrived, I took a deep breath and tried to stay calm.The English exam was divided into several sections, including reading comprehension, grammar and vocabulary, and writing. The reading comprehension section required us to read a few passages and answer questions about the main ideas, details, and author's purpose. I found this section manageable, thanks to all the practice we had done in class.The grammar and vocabulary section was a bit more challenging, as it tested our knowledge of complex rules and word meanings. But I tried to approach each question methodically, applying the strategies Mrs. Thompson had taught us.Then came the writing section – the part I had been both dreading and looking forward to. The prompt asked us to write a narrative essay about a memorable experience from our childhood. As I read the prompt, ideas started swirling in my mind. I took a few minutes to jot down an outline and organize my thoughts before starting to write.As I wrote, I tried to keep Mrs. Thompson's advice in mind. I focused on creating a clear structure with an engaging introduction, well-developed body paragraphs, and a satisfying conclusion. I also made an effort to use descriptive language and varied sentence structures to keep the reader interested.Time seemed to fly by as I wrote, and before I knew it, the exam period was over. I double-checked my work for any mistakes and then turned in my exam with a sense of relief and accomplishment.In the days that followed, I couldn't help but replay certain parts of the exam in my mind. Had I analyzed the readingpassages correctly? Did my grammar and vocabulary knowledge hold up? And most importantly, had I crafted a compelling narrative essay?Finally, the day came when Mrs. Thompson handed back our graded exams. With trembling hands, I flipped through the pages, eager to see how I had performed. To my delight, I had done well – not just on the English exam, but on all my exams.As I looked at the comments and feedback from Mrs. Thompson, I felt a sense of pride and gratification. All the hard work and late nights of studying had paid off. But more importantly, I realized how much I had grown as a student and as a writer over the course of the semester.The final exams had been a challenge, but they had also been a valuable learning experience. They had pushed me to apply everything I had learned, think critically, and express myself clearly and creatively. And while I was relieved to be done with them, I knew that the skills I had developed would be invaluable as I continued my academic journey.As I looked ahead to the second semester of 8th grade, I felt a renewed sense of determination and excitement. I couldn't wait to see what new challenges and opportunities awaited me in my English class and all my other subjects. With the final examsbehind me, I felt more confident and prepared than ever to tackle whatever came my way.篇6My Final Exams in 8th Grade During the Covid-19 PandemicWow, what a year 2020 was! It felt like the world turned upside down because of the coronavirus pandemic. Schools were closed, we had to stay home for months, and everything was just weird and different. But one thing that didn't change was the need to take our final exams in 8th grade. Let me tell you all about how strange and crazy those exams were!It all started a few weeks before the exams were supposed to happen. Our teachers told us that because of the pandemic, we wouldn't be able to take the exams at school like normal. Instead, we'd have to take them online from our homes. I remember thinking "Oh cool, I get to take my exams in my pajamas!" But it wasn't that simple...First, my parents had to sign all these forms saying they would make sure I didn't cheat or get any help during the exams. They set up a little desk area for me in the living room with my laptop and nothing else around. No books, no phones, nonothing. Just me and that laptop for hours on end. It felt like I was in exam prison!The exams were split into different days and time slots. My first one was math and I was really nervous. I had to log into this weird portal and do all these test compliance things like showing my desk area with a webcam. The math exam itself was okay, just a bunch of questions and equations to solve. But it was sooo hard to concentrate at home! My little brother kept running around yelling and there were all these distracting noises. Plus I kept getting scared the internet would cut out and I'd get logged off. Talk about stressful!English was a couple days later and that was a whole different challenge. We had to write out essays and answers in this lockdown browser that didn't let you go anywhere else. My hands cramped up so bad from typing for hours straight. And the reading comprehension section was brutal - having to read these tiny passages on a laptop screen. Why couldn't we just get physical papers like at school?Science and history were just as intensive in their own ways. I had to do online labs for science and show my work by writing on my webcam. And history had so much typing to explain allthe concepts and dates. By the time I finished those last few exams, my brain felt like mush.The weirdest part though? We didn't even get our exam scores back until like a month later! Normally we get them the next week, but with everything being online, it took forever for teachers to go through and grade them all. I spent the whole summer wondering how I did and if I'd have to go to summer school. That feeling of uncertainty was almost as bad as the exams themselves.Don't get me wrong, I know my teachers worked extremely hard to make this all possible during the pandemic. And I'm grateful I got to finish 8th grade and take those important exams, even if the experience was totally different to anything I could have imagined. Looking back, those final exams from home were just another example of how crazy and unprecedented 2020 was. I'll always remember having to take high-stakes tests from my living room, with my parents frantically trying to keep my siblings quiet in the other room. Definitely one for the memory books!While the pandemic disrupted so much of normal life, I learned that some things had to go on no matter what - including getting rid of those annoying finals before summer! Ijust hope by high school, things are back to in-person testing. Because as memorable and unique as my 2020 exams were, I'm good without having to ever do that again! Fingers crossed for a more normal, less world-turning-upside-down future from here on out.。
