Unit 8 Section A Animals or children?—A scientist's choice动物还是孩子？——一位科学家的选择1 I am the enemy! I am one of those cursed, cruel physician scientists involved in animal research. These rumors sting, for I have never thought of myself as an evil person. I became a children's doctor because of my love for children and my supreme desire to keep them healthy. During medical school and residency, I saw many children die of cancer and bloodshed from injury —circumstances against which medicine has made great progress but still has a long way to go. More importantly, I also saw children healthy thanks to advances in medical science such as infant breathing support, powerful new medicines and surgical techniques and the entire field of organ transplantation. My desire to tip the scales in favor of healthy, happy children drew me to medical research.1 我就是那个敌人！我就是那些被人诅咒的、残忍的、搞动物实验的医生科学家之一。

Early farmers grew rice and 14 pigs and chickens in the valleys. They cut down the trees and burnt them.

八年级下学期第七单元英语作文：探索未知，拥抱变化一、开启新知的勇气之门As we embark on the seventh unit of our eighth-grade semester, we find ourselves standing at the threshold of a new intellectual adventure. This journey is not merely about mastering facts and figures; it's a call to embark on a thrilling quest to explore the vast expanse of unknown territories within and around us. With open minds and hearts, we embrace the challenge of delving into unfamiliar topics, ready to be amazed, inspired, and sometimes even puzzled by what we discover. Each lesson becomes a treasure hunt, where we gather clues, form hypotheses, and eventually unravel the mysteries that lie hidden in the depths of knowledge.二、变化中的成长轨迹Change, the ever-present companion on our academic voyage, takes on a special significance in this unit. We learn that just as the world around us is constantly evolving, so too must our perspectives and understanding. By engaging with diverse perspectives and ideas, we foster resilience and adaptability –skills essential for navigating the complexities of life. Whether it's through discussions that challenge our preconceptions or projects that push us out of our comfort zones, we recognize that every encounter with the unknown is an opportunity for growth. We come to understand that change, though sometimes daunting, is also the catalyst for personal transformation and the fuel that drives progress.三、创意与合作的火花碰撞One of the most rewarding aspects of this unit is the emphasis on creativity and collaboration. As we delve deeper into our studies, we are encouraged to think outside the box, to question the status quo, and to express ourselves uniquely. Group projects become platforms where diverse minds converge, sparking a flurry of innovative ideas. We learn that the best solutions often emerge from the synergy of multiplevoices, each contributing their unique perspective to the mix. This process not only enriches our learning experience but also fosters a sense of camaraderie and mutual respect among our peers. As we work together, we realize that the sum of our parts is greater than the whole, and that through collaboration, we can achieve feats we never thought possible.四、展望未来，心怀希望As we conclude this unit, we are left with a renewed sense of excitement and anticipation for what lies ahead. The journey through the unknown has taught us that fear of the unfamiliar should not deter us from exploring; rather, it should fuel our curiosity and determination. We carry with us the lessons learned –the importance of courage, the power of adaptability, the beauty of creativity, and the strength of teamwork. With these tools in our arsenal, we are better equipped to face the challenges that life may throw our way. As we step into the future, we do so with hearts full of hope, minds brimming with ideas, and a spirit that is unafraid of the unknown. For we know that in the end, it is our willingness to embrace change and our courage to explore that will shape our destiny and define our success.总结：八年级下学期第七单元的学习，不仅是一场知识的盛宴，更是一次心灵的洗礼。
第七单元英语作文八年级下册Everyone has dreams, and my dream is to become a successful scientist. Ever since I was a child, I have been fascinated by the natural world and how things work. I remember the first time I conducted a simple experiment in my school science class. We mixed different liquids and observed the changes that occurred. This experience ignited a spark in me and made me realize that I wanted to dedicate my life to science.To achieve my dream of becoming a scientist, I know I need to work hard in my studies. I pay special attention to subjects like biology, chemistry, and physics because they form the foundation of scientific knowledge. My teachers often encourage me to ask questions and think critically about the world around me. I enjoy reading books and articles about various scientific discoveries, and I often find myselfamazed by what scientists have accomplished throughout history.Moreover, I believe that practical experience is just as important as theoretical knowledge. Therefore, I am actively seeking opportunities to participate in science fairs and competitions. These events allow me to engage with my peers and showcase my projects while learning from others. Last year, I participated in a science fair where I created a model of a renewable energy source. This project not only deepened my understanding of energy but also taught me valuable skills in teamwork and presentation.In addition to my academic pursuits, I am also passionate about environmental issues. I often volunteer for localclean-up campaigns and participate in initiatives aimed at raising awareness about climate change. I understand that scientists hold a crucial role in solving the challenges our planet faces, and I want to be part of that solution. Byresearching new technologies and finding ways to protect our environment, I hope to contribute to a healthier planet for future generations.Looking ahead, I aspire to attend a prestigiousuniversity to further my education in science. I want to explore various branches of science and ultimately specialize in environmental science. My goal is to conduct innovative research that can lead to sustainable practices and policies that benefit our world. I dream of working alongside other passionate scientists, conducting experiments, and making discoveries that can change lives.In conclusion, my dream future as a scientist is shaped by my curiosity, dedication, and passion for the environment.I am fully aware that the path to achieving my dreams will be challenging, but I am committed to overcoming obstacles and continuously learning. I believe that with hard work andperseverance, I can make a meaningful impact on the world through science.。

The Red Delicious apple is likely to lose its title as the most popular apple this year, which it held for more than half a century. The U.S. Apple Association is projecting, that the Gala apple will usurp（夺取）the Red Delicious for the top spot.The group, which advocates on behalf of 7,500 apple growers and 400 companies in the apple business, predicted that the U. S. would grow 52.4 million Gala apples in 2018, up 5.9 percent from a year earlier. Red Delicious apple production is expected to fall 10.7 percent to 51.7 million.Consumers apparently like the Gala's "taste, texture（口感）and sweetness," the U.S. Apple Association said in a statement. "The rise in production of newer varieties of apples aimed at the fresh consumption domestic market has caused demand for the Red Delicious to decline." said Mark Seetin, the association's director of regulatory and industry affairs.The Granny Smith, Fuji and Honeycrisp apples are expected to rank third, fourth and fifth. The association predicted that within a year or two the Honeycrisp may pass the Granny Smith and Fuji, jumping into third place. The production of the apple rose 21.8 percent to 23.5 million this year. That puts it ahead of the Golden Delicious apple for the first time. The Honeycrisp was created by the University of Minnesota's apple breeding（培育）program only 21 years ago. It typically costs more than its competitors.Until the 1970s, Americans had only a few choices of apples. While the Golden Delicious offered a color contrast and the Granny Smith brought tartness（酸味）to the table, the Red Delicious was the star, heavily promoted by Washington state growers. Then wholesalers began looking for tastier varieties, finding them overseas in Japan, home to the Fuji, and New Zealand, which had the Braeburn and Gala.（1）How does the author prove Americans' preference for the Gala?A.By using statistics.B.By listing examples.C.By explaining causes.D.By presenting research findings.（2）What do we know about the Honeycrisp?A.It is sour in flavor.B.It is light in color.C.It is gaining popularity.D.It is losing its price advantage.（3）Which of the following comes from New Zealand?A.The Fuji.B.The Honeycrisp.C.The Braeburn.D.The Granny Smith.（4）What does the text mainly tell us?A.Why Americans eat apples from different countries.B.How different apples are becoming popular in America.C.How American farmers choose their apple growing types.D.Why the Red Delicious was Americans' favorite for 50 years.causal inferences rather than simply finding patterns. "At some point—you know, if you're intelligent—you realize maybe there's something else out there," he says.【长难句分析】1.

初二第8单元英语作文下册As the sun peeks through the curtains, I know another day has begun. Today is no different from the rest, filled with the usual routine of a middle school student in the second yearof junior high. Let me take you through my day.Morning RoutineMy day starts early at 6:30 am. After freshening up, I have breakfast with my family, which usually consists of some toast, an egg, and a glass of milk. This is a crucial part of my day as it provides me with the energy I need to stayactive throughout the morning.School TimeAt 7:30 am sharp, I leave for school. The journey to schoolis about 20 minutes by bus, and I often use this time toreview my notes or listen to English learning podcasts to improve my language skills.Once at school, the first class begins at 8:00 am. Ourclasses are 45 minutes long with a 10-minute break in between. English is one of my favorite subjects, and today we are learning about the past continuous tense, which isfascinating as it helps me understand how to talk aboutactions that were happening at a specific time in the past.Lunch BreakLunchtime is at 12:00 pm. The school canteen offers a variety of dishes, but today I decide to have some rice, vegetables, and a small portion of chicken. Eating a balanced meal is important for maintaining my health and focus.Afternoon ClassesAfter lunch, we have a couple more classes, including math and physics. I find these subjects challenging but also very rewarding. The afternoon can be tiring, so I make sure to stay hydrated and take short breaks to rest my eyes and stretch my legs.Extracurricular ActivitiesAround 3:30 pm, school officially ends, but I have extracurricular activities that I participate in. Today, I am attending the school's English debate club where we discuss global issues and practice our public speaking skills.Homework TimeOnce I get home, it's time to tackle my homework. I have assignments from various subjects, but I always start with English. Today, I am working on a composition about "The Importance of Biodiversity," which is not only a school task but also a topic I am genuinely interested in.Evening RelaxationAfter finishing my homework, I take some time to relax. I enjoy reading books, and today I am reading "The Old Man and the Sea" for my English literature class. Reading not only helps me unwind but also improves my vocabulary and understanding of complex narratives.BedtimeBefore bed, I make sure to prepare my school bag for the next day and set my alarm. I usually sleep by 9:00 pm to ensure I get enough rest for another day of learning and growing.And that's a typical day in my life as a second-year middle school student. It's filled with learning, challenges, and personal development, all of which are essential for my journey towards becoming a well-rounded individual.。
