全国英语等级考试考前冲刺模拟卷一级听力

全国英语等级考试考前冲刺模拟卷一级听力全文共6篇示例,供读者参考篇1Hi there! My name is Emily and I'm going to tell you all about my last summer vacation. It was the best summer ever! Let me start from the very beginning.On the last day of school before summer break, my teacher Ms. Johnson gave us all big buckets of sidewalk chalk. She said we could draw pictures and write messages on the playground over the summer. I was so excited because I love art class and drawing is my favorite thing to do.The next morning after I woke up, I raced downstairs for breakfast. My mom made my favorite - chocolate chip pancakes! After I ate, I grabbed my chalk bucket and ran outside. The hot sun was shining brightly and I got right to work decorating the driveway with rainbows, flowers, and smiley faces.A little while later, my best friend Katie came over. Katie lives right next door, so we always play together. She saw my chalk drawings and thought they looked awesome. Katie had gotten a new sketching pad and colored pencils for her birthday, so wedecided to have an art day. We spent hours drawing pictures and making up stories about princesses, unicorns, and dragons battling evil wizards.The next few weeks were filled with fun activities like swimming at the town pool, having lemonade stands, and catching fireflies at night in the backyard. But I think my very favorite day was when my parents took me and my little brother to the county fair!We rode so many fun rides like the Tilt-a-Whirl, the Scrambler, and the biggest rollercoaster I've ever seen called The Cosmic Comet. I was a little scared at first, but my dad said he would go on all the big rides with me. After the first few coasters, I was hooked and couldn't get enough of the loops, corkscrews and feeling of flying through the air.At the fair, we also saw a magic show, a petting zoo with baby piglets and goats, and a circus with elephants, clowns and acrobats. For dinner, we had classic fair food - corn dogs, cotton candy, and funnel cakes. It was truly the best day ever!Eventually though, summer came to an end. The week before school started, my family went on our annual camping trip to Lake Wildwood. I loved canoeing across the lake, roastingmarshmallows around the campfire, and sleeping in our big tent under a canopy of bright stars.On the last night, we caught tons of fireflies and kept them glowing in a jar by our tent. We made shadow puppets and told ghost stories until it got too dark and scary to stay up any later. I had a weird dream that night about being chased by a giant mosquito!The next morning, we packed up camp and headed back home to get ready for the new school year. While I was sad summer was over, I couldn't wait to see all my friends again and show them the pictures I drew and tell them stories about my awesome summer adventures.Now I'm back in Ms. Johnson's 3rd grade class working hard on my reading, writing, and math skills. But I'm already counting down the days until next summer when I can enjoy warm sunshine, no homework, and making more incredible memories!篇2Hi everyone! My name is Emily and I'm 9 years old. I'm going to tell you all about my favorite day of the year - my birthday! Every year, my mom and dad make my birthday really special and fun.It usually starts the night before my birthday. After I go to bed, my parents decorate the living room with balloons, streamers, and a big 'Happy Birthday' banner. They also wrap all my presents and put them on the living room table. I always try to sneak out of my room to peek at the presents, but my parents are too smart for that!On my birthday morning, I wake up early because I'm so excited. My parents always let me open one small present before breakfast as a little treat. This year, I got a new backpack with unicorns on it! I love backpacks and I love unicorns, so it was the perfect little gift.After I open that first present, we have a big birthday breakfast. My favorite is when my mom makes chocolate chip pancakes in fun shapes like hearts or stars. She always puts a candle in one of the pancakes and I get to make a birthday wish before blowing it out. My dad sings "Happy Birthday" to me in a really silly voice which makes me laugh so hard!Once we're done with breakfast, it's finally time to open the rest of my presents! I try to open them slowly to make the fun last longer. My parents always get me fun toys, games, books, and clothes. This year, I got a huge art set with loads of colored pencils, paints, brushes, and sketch pads. I'm really into art rightnow so I was super excited about that gift. My grandparents sent me money, which I plan to save up to buy a new bike.In the afternoon, it's time for my birthday party with my friends! My parents decorate the backyard with balloons and banners. We play fun games like pin the tail on the donkey, musical chairs, and freeze dance. There's always lots of laughing and screaming when we all get together.My favorite part is when it's time for cake and ice cream! My mom always bakes the most delicious cake - usually chocolate but sometimes funfetti. This year, it was a huge chocolate cake shaped like a castle! It had so many candles that I needed help from my friends to blow them all out. After we stuff ourselves with cake, we open presents. My friends always give me cool new board games, dolls, art supplies, and other fun toys to play with.After all the fun and excitement, I'm always completely tuckered out by the end of the day. I head to bed feeling so happy, loved, and thankful for my wonderful family and friends. I can't wait to do it all over again next year! That's what my perfect birthday is like. Thanks for listening!篇3Hi there! My name is Emma, and I'm a 10-year-old student who loves learning English. Today, I'm going to share with you my experience of preparing for the National English Proficiency Test, Level 1. Get ready for some fun and excitement!First things first, let me tell you about my English class. We have the coolest teacher ever, Ms. Johnson! She's always full of energy and makes learning English so much fun. She often uses games, songs, and stories to help us learn new words and grammar rules. One of my favorite activities is when she plays a song, and we have to fill in the missing lyrics with the correct words. It's like a musical adventure every time!Speaking of adventures, last week, we went on a field trip to the local museum. Ms. Johnson told us to pay close attention to the tour guide's explanations because there would be questions about it later. The museum was amazing! We saw dinosaur skeletons, ancient artifacts, and even a replica of a space shuttle. My favorite part was the interactive science exhibit, where we got to do cool experiments like making a volcano erupt with baking soda and vinegar. So much fun!After the field trip, Ms. Johnson gave us a listening comprehension exercise based on the tour guide's explanations. At first, I found it a bit challenging to remember all the details,but then I realized that I should listen for keywords and take notes. It really helped me understand the main points better.Now, let me tell you about my study routine for the listening comprehension part of the English test. Every evening, I practice with my parents or older sister. They read passages from practice materials or play audio recordings, and I have to answer questions based on what I hear. Sometimes, it's tricky to understand accents or unfamiliar words, but I've learned some strategies to help me.One strategy is to focus on the context clues. For example, if I hear a word I don't know but it's mentioned along with other words related to food, I can guess that it might be a type of dish or ingredient. Another strategy is to listen for signal words like "first," "next," "finally," which can help me follow the sequence of events or instructions.Another thing that I find really helpful is to visualize the scenes or situations described in the listening passage. If it's a story about a girl going to the park, I imagine her walking through the gate, seeing the playground, and hearing the birds chirping. Creating these mental pictures makes it easier for me to remember the details.Speaking of journeys, last month, my family went on a trip to visit my grandparents in another city. During the long car ride, my parents played an audiobook for me to practice my listening skills. It was about a group of friends who discovered a secret treasure map and went on an exciting adventure to find the buried treasure. I was so captivated by the story that I didn't even realize how much time had passed!As you can see, preparing for the listening comprehension part of the English test can be a lot of fun when you approach it with the right mindset and strategies. It's all about being an active listener, using your imagination, and finding materials that engage you.Well, that's all from me for now. I hope my experiences have given you some useful tips and inspiration for your own English listening practice. Remember, the key is to make it enjoyable and engaging, just like one of those thrilling adventure stories. Good luck, and happy listening!篇4My Super Fun Summer VacationHi there! My name is Emma and I'm going to tell you all about my awesome summer vacation this year. It was the bestsummer ever! I had so much fun and went on all kinds of cool adventures.The summer started out with my birthday in June. I turned 9 years old! My parents threw me a big birthday party and invited all my friends from school. We had the party at a trampoline park and it was a blast. We got to jump around for hours, play dodgeball, and they even had a foam pit to jump into. After we were all tired out from jumping, we had pizza, cake, and ice cream. I got tons of great presents too - new books, arts and crafts supplies, and even a cute new stuffed animal. It was the perfect way to kick off summer!A few weeks later, my family went on a big road trip. We drove all the way from our house in Ohio to Florida to go to the beach for a week. The drive took forever, but my little brother and I kept ourselves busy by playing road trip games like I Spy and the license plate game. We also watched movies and played on our tablets. When we finally made it to Florida, we stayed in a big beach house right by the ocean. Every day we'd wake up and head straight to the beach to swim, build sandcastles, look for seashells, and play in the waves. My favorite was when we went boogie boarding - I caught some amazing waves! In the evenings, we'd walk along the beach and watch the beautifulsunsets. We also went mini golfing, to an amusement park, and did lots of other fun activities. I never wanted that trip to end!After we got home from Florida, it was time for summer camp! I went to day camp at our local park for two weeks. We did all kinds of cool outdoor activities like hiking, canoeing, archery, and survival skills. We even went on a camping trip for three days and two nights in the middle of the camp session. We all had to help set up the tents, cook our meals over a campfire, and sleep outdoors under the stars. I had never gone camping before so it was a really fun new experience for me. My favorite part was definitely the campfire at night where we sang silly songs, told ghost stories, and made s'mores!When I wasn't at camp, I spent lots of time just hanging out with my friends in the neighborhood. We'd have lemonade stands, have water balloon fights, ride our bikes around, and play games in the backyard. A group of us also started a fun club where we did arts and crafts projects together. We made friendship bracelets, painted rocks, and had talent shows. One of our club meetings was even a fun spa day where we did homemade facemasks and gave each other pedicures. So silly but so fun!As summer came to an end, my family took one final trip to Cedar Point, which is a huge amusement park a few hours away with the craziest roller coasters ever. I was a little nervous to go on the big coasters at first, but they ended up being so thrilling and exciting. My favorite was the Millennium Force - it goes so high and so fast! We spent two days at the park and I went on every single roller coaster. I also played games and won a couple of stuffed animal prizes. We had such a blast!Now it's back to school, but I have the best memories from my amazing summer vacation. Between my birthday party, our beach trip, summer camp, all the fun with friends, and Cedar Point, it was definitely a summer I'll never forget. I can't wait for more adventures next summer!篇5Hi there! My name is Emily and I'm 10 years old. I'm going to tell you all about my summer vacation and the fun adventures I had! Get ready because there's a lot to cover.The last day of school was the best feeling ever. No more homework, no more tests, just freedom for two whole months! My family and I didn't have any big trips planned though. Myparents both had to work during the days so we stayed home in our little town. But that didn't stop us from having a blast!The first week, my best friend Amanda came over almost every day. We spent tons of time riding our bikes around the neighborhood and exploring the woods behind my house. One day, we decided to have a lemonade stand in my front yard. We made a big sign and mixed up a huge pitcher of lemonade. Lots of neighbors stopped by on their evening walks to buy a cup for 25 cents! By the end of the day, we had made 7 which seemed like a fortune to us. We used the money to buy ice cream at Daisy's Dairy the next day.The second week, my aunt and uncle came to visit from across the country. They brought my cousins Jake and Emma with them. Having four extra people in our little house was crazy! But it was so much fun to have built-in friends to play with. Jake is 12 and Emma is 8 so we had to take turns picking what games we played. One day it was Jake's choice so we played his favourite video game for hours. I'm not very good at it but my cousins helped me and it was still really fun. The next day was my turn and I chose for us to have a big backyard camping adventure! We pitched a tent, built a fake campfire out of stones,and made s'mores. We even pretended there were bears and had to defend our camp! It was Emma's favourite day.During their visit, we also went to the town pool a couple times which was amazing on the really hot days. I practiced my swimming skills and even showed off my new diving tricks to my cousins. They thought I was a great swimmer! We also took them strawberry picking at the local farm one morning. We had strawberry shortcake for dessert that night - so delicious!After my cousins left, we had a few lazy weeks at home. I spent a lot of time reading books from this super cool summer reading program at the library. The librarian gave me a special folder to keep track of all the books I read. She said if I read 20 books, I would get a prize at the end of the summer! I ended up reading 23 books and won a stuffed animal and a gift card to the bookstore. Score! I also did some baking with my mom those weeks. We made chocolate chip cookies, banana bread, and my favorite - snickerdoodles! Yum.Towards the end of the summer, my parents surprised my brother and me with a three-day camping trip up north! We stayed at a lakeside campground and spent the days swimming, canoeing, and roasting marshmallows over the fire pit. My dad taught us how to fish off the dock and I even caught a tinysunfish! We saw wild rabbits and deer walking around the campground in the evening which was amazing. Sleeping in the tent at night was a little hard with the sounds of nature all around, but I felt like a brave explorer. We didn't have any showers though so we all smelled pretty ripe by the time we headed home!My last big summer adventure was going to Camp Sunny Days for a week at the end of August. It's a day camp not too far from my house where you get to do all sorts of fun activities like arts and crafts, sports, camping skills, and more. My favorite part was getting to select my activities each day like making friendship bracelets, playing soccer, or practicing archery. I made a ton of new friends and didn't want the week to end!And just like that, my wonderful summer was over. We had one last big barbecue with my grandparents and aunt and uncle to celebrate before I headed back to school. While I was sad for summer to be done, I was also excited to see my friends and start 5th grade. I have so many amazing memories from those sunny, carefree days. I can't wait for next summer's adventures!篇6Hi everyone! My name is Sarah and I'm 10 years old. I go to Oakwood Elementary School here in town. Today I want to tell you all about my favorite subject - science! We just finished up a really cool unit on animal habitats and ecosystems. I learned so much interesting stuff!First off, we learned what an ecosystem is. It's all the living things like plants and animals that live together in one place, along with the non-living things like water, air, and soil. The living and non-living things are all connected and need each other to survive. Pretty neat, right?Then we studied different habitats, which are the specific places where plants and animals live and find everything they need. Like a forest is a habitat for deer, squirrels, birds and so many other creatures. A pond is a habitat for fish, frogs, ducks and other water-loving animals and plants. Even your backyard could be a tiny habitat for bugs, worms and small critters!My favorite habitat we learned about was the rainforest. Can you believe that rainforests are home to over half of all the plant and animal species on Earth? That's millions and millions of different living things all packed into those tropical forest habitats. The rainforest is like a big apartment building, withcreatures living in the trees, on the ground, and even underground. It's truly an amazing interconnected ecosystem.We did lots of fun activities and experiments too. One time, we built our own mini-ecosystems inside plastic bottles with soil, plants, and a little water. We had to make sure all the elements an ecosystem needs were inside - like sunlight, air, nutrients, and decomposers to break down waste. It was awesome watching them grow and change over a few weeks.Another cool thing we did was examine samples of soil, water, and decaying matter under microscopes. We found tons of tiny organisms like bacteria, mold, and microbes that help decompose things and recycle nutrients back into the ecosystem. Who knew dirt could be so fascinating to look at up close?The most exciting part though was when we went on a field trip to Elkwood Nature Reserve just outside of town. We got to explore different forest and wetland habitats and see examples of producers, consumers, and decomposers all working together. We saw deer, rabbits, all kinds of birds, frogs, turtles, and insects - even found some snake skins! Our teacher taught us how to identify different plant and animal species and how they've adapted to survive in their particular habitats.On the way back to school, our bus drove by a construction site where a new shopping mall is being built. That made me sad because it means destroying the forest ecosystem that was there before. Our teacher told us that habitat loss is the biggest threat to ecosystems and endangered species nowadays. With more land being taken over for houses, roads, farms and buildings, lots of animals are losing their homes and food sources. It's a serious problem that people need to care more about.Still, learning all about these incredible habitats and ecosystems has been fascinating. My biggest takeaway is just how complex and interconnected everything in nature really is. From the smallest microbe in the soil to the largest predator roaming the rainforest, each species and habitat is precious and plays an important role. We need to appreciate and protect these amazing ecosystems while we still can. As kids, I think it's our job to take good care of the planet we're inheriting!Anyway, those are some of the highlights from our really fun and educational science unit. Let me know if you have any other questions! I better run for now though - my mom's calling me in for dinner. Thanks for listening, bye!。

高考模拟考试冲刺发言稿范文

高考模拟考试冲刺发言稿范文

高考模拟考试冲刺发言稿范文亲爱的同学们:大家好!今天咱们聚在一起,就是要给即将到来的高考模拟考试来个最后的冲锋。

我站在这里,就像一个即将带领大家冲向战场的小队长,不过这个战场没有硝烟,只有满卷的题目。

咱先说说这模拟考试啊,它就像是高考前的一场彩排。

你想啊,要是一场大戏,不先彩排几次,上台能不慌吗?这模拟考就是让我们提前找找高考的感觉,试试水温。

你要是在这模拟考里把问题都暴露出来了,那简直就是捡到宝了,为啥呢?因为你还有时间去解决这些问题啊,总比在高考的时候才发现要好得多吧。

就像打游戏,咱们现在还在新手村附近做最后的修炼,把技能都点满,把装备都升级。

那怎么才能在这最后的冲刺阶段让自己变得更强呢?知识复习得有条理。

不能像没头的苍蝇一样,东一榔头西一棒子。

比如说数学,你不能一会儿看看函数,一会儿又跑去做立体几何,得按照章节、按照题型系统地来。

就像整理衣柜一样,把知识都整整齐齐地码放好,要用的时候,一下子就能找到。

语文也是,那些古诗词、文言文,就像我们的老朋友,要时不时地去串串门,加深一下感情,这样考试的时候,它们才会很乐意地出来帮我们的忙。

还有啊,咱们得合理安排时间。

这就好比做饭,你不能把所有的菜都一股脑儿地丢进锅里,得有个先后顺序。

每天的学习时间就这么多,你得把时间分配好,哪科弱就多给点时间,但也不能把其他科给冷落了。

就像你不能只吃米饭不吃菜,或者只吃菜不吃饭一样,得均衡。

另外,心态也很重要。

别把模拟考当成世界末日,考好了,别骄傲得像只开屏的孔雀,觉得自己天下无敌了;考砸了,也别垂头丧气,像个斗败的公鸡。

要知道,这只是模拟考,是我们成长的垫脚石。

我听说有个同学,上次模拟考没考好,哭了一鼻子,结果后面复习的时候也没心思,你说这多傻呀。

这一次没考好,就当是给高考的敌人送了个假情报,让他们放松警惕,咱们偷偷地在后面憋大招呢。

我想跟大家说,咱们这一路就像一场马拉松,现在已经到了最后的冲刺阶段。

虽然大家都有点累,但是咬咬牙就过去了。

四编考前指导与模拟冲刺说课材料

四编考前指导与模拟冲刺说课材料

2.形成网络,提升思维——“蓦然回首” 当前,高三历史复习应该对知识重新整合,形成用课本标题,形成对课本的整体把握。读书 不宜翻开即读,不妨先回忆某一阶段相关章、节甚至 子目的标题,因为标题是“纲”,对这些“纲”的综合、 归纳便形成了“历史的阶段特征、基本线索”。在此基 础上,有选择地梳理一些重要的历史人物、历史事件 、典章制度和历史概念等。由于知识的内在逻辑关系 ,必然形成与其他知识点的“互动”,所谓“纲举目张” 就是这样。其次,要注重知识的横向与纵向联系。
3.形成一种整体世界观 从近两年的高考试题来看,考查学生归纳能力的比 较多。整体世界观要求从纵向看历史事件产生、发 展以及事件所起到的作用。这有助于学生更深层次 地理解历史事件,而不是割裂地看历史事件。 4.善思多问,提高效率 解题中不可避免会遇到困难,有一些题自己确实不 会做,这时就不要花很多时间苦思冥想,可以请教 老师和同学,以节省时间提高效率。
7.“三项意识” 一要破除大局已定的观念,现在应该是高考冲刺阶 段,成绩的提升仍有较大空间,千万不要自暴自弃!
二要注意反思和总结。把做过的考试卷拿出来,注 意做错的题目,分析做错的原因,然后在复习和训 练中针对性地改进,最终成绩会提高。另外,还要 注意近两年高考主观题的答题思路和答案陈述,并 有意识地模仿。
2.审题要慢,答题要快 有些考生只知道一味求快,往往审题不清便匆忙动笔, 结果掉进命题的“陷阱”之中,即所谓的“欲速则不达” ,看错一个词都可能会“失足成憾”,所以审题一定要 慢,有了这个“慢”,才能形成完整的符合逻辑的解题 思路,才有答题的“快”。 第一步:审中心词,即“答什么”。这一步同学们基本 上都能做到,但一定要做到“准”和“全”。非选择题别 忘了审答题方式。
第二步:审主体,即“答什么的什么”。这一步最容易 被同学们所忽视,但命题人经常在此设置“陷阱”。
