Unitl Science and scientistsWrite an essay about scientific spiritsSample Writing:Great Scientific MindsWhen we consider the great minds of many centuries and ask the question of what makes someone a great scientist, there are many aspects we should evaluate. But which ones are most important? Is it their inventions, cures, or solutions to problems? Is it the personal challenges they had to face? Or is it their overall character?Looking at the lives of Qian Xuesen and Stephen Hawking, some common characteristics surface: they are knowledgeable, gifted, self-sacrificing for the greater good of the country or humanity, brave, and determined. In short, they have to tenaciously chase down solutions to big problems and not let discouragement set in during their discovery process.We can see this in Qian Xueshen,s life, pioneering to another country to work with and inspire like-minded people in his field and to collaborate on their work. We can see it in his vigour to return to China and lead their aerospace programme through its birthing stages. We saw the determination and devotion to accuracy and truth on the part of Stephen Hawking from his youngest days through the decades he fought for his body while his mind progressed into the arena of geniuses.The definition of scientific spirit is to, above all else, be willing and able to grasp a problem or a question and not let go of it until knowledge, creative power, and collaboration have brought a clear answer. Then this same mind must believe in its findings enough to bravely present them, prove, and perfect them for the betterment of the quality and sustainability of life all over the world. It is to look squarely, ask questions, and never give up trying.Unit 2 Bridging CulturesWrite a letter to the editor expressing your own opinions about studying abroadSample Letter Dear Editor,Many people ask the question,Why study abroad? After all, there are many great universities and schools in China that attract great professors both local and foreign.'11 think that while this is true, this gets things slightly wrong. The question isn,t that people think the quality of their local university is not adequate, but rather how studying abroad helps and benefits the individuals in their own study and career plans.By studying abroad, Chinese students get a better understanding of other cultures and countries, and learn to see themselves as global citizens.As a result, they can better understand China,s place in the world and how they can contribute to world peace and development.In addition, overseas students can learn cross-cultural communication skills, which will help them understand how they can participate on the world stage. There are so many places in the world with hurting, needy people.With such skills and knowledge, they can better lend them a helping hand.Finally, when our students return home, they can share their experience with others. There is a wide open world which they can contribute to, but only if they first learn about people from other countries, and their struggles and challenges.In conclusion, the best way to get is by giving, and the easiest way to be loved is by loving others. I hope everyone will agree that there is a wonderful world out there which can be made better by our presence, but they need to learn how they can contribute and help, and they can best do this through student exchange.Best regards, Liu PingUnit3 Food and CultureWrite an essay about your own dietSample writing:Overall, I think I have healthy eating habits. As for the things that I am doing right, I am eating a variety of healthy foods and trying to eat fresh food as much as possible.After noting down what I have eaten over the last three days, I can see lots of healthy and nutritious things on the list, such as fish, eggs, fruit, and salad. Put simply, most of my diet contains food that is good for my body. The fruit and vegetables that I eat are full of vitamins and minerals. And they contain much more nutrition than processed foods. Fresh food is also lower in sugar, salt, and fat.However, I do have some bad eating habits. There are some foods that I should not eat too much of. For example, rice and bread are healthy, but eating too much can create too much unused energy and cause you to gain weight and feel tired. I also really like eating pre-made steamed buns and tomato soup from store, I now know they contain far too much sugar, salt, and fat. Also, some types of meat contain a lot of fat, so I should be careful with how much I consume. The same goes for the pancakes I buy on the street. They are delicious, but they are by no means healthy, and I should be careful with how often I consume them.In addition to the above, I also sometimes find myself too busy and forget to eat. I also have a hard time refusing sweets from others, even though I know they are bad for me.I should improve my bad eating habits by always taking th
