Basic arithmetic operations: 1+1 is the foundation of all other arithmetic operations, such as addition, subtraction, multiplication, and division.
b. Counting and measurement: 1+1 is used in counting objects, where each additional object represents a unit increase. In measurement, 1+1 can be used to measure the increase in a quantity, such as distance, time, or weight.
c. Physics: In physics, 1+1 is used to calculate the sum of forces, energy, or mass. For example, the formula for momentum (p) is p = m * v, where m is the mass, and v is the velocity. In this case, 1+1 represents the addition of the mass and velocity of an object.
d. Computer science: In programming, 1+1 is used in algorithms and data structures to perform various operations, such as adding elements in a list or calculating the sum of a series of numbers.
In summary, 1+1=2 is a fundamental mathematical concept that serves as the basis for many mathematical and scientific operations. It is a simple formula with numerous applications in everyday life and across various disciplines.”
“第三题，讲一下你转学有什么感受。”
李佳站了起来。
“ Hello everyone,
I'm here to share my recent experience about transferring to a new school. I used to attend a different school, and now I'm excited to start a new chapter in my life at my current institution.
To begin with, let me tell you a little bit about my old school. It was a great place with wonderful teachers and supportive classmates. I have many fond memories of my time there, and I will always be grateful for the experiences and knowledge I gained. However, I started to feel that the school wasn't the right fit for me, and I knew it was time for a change.
Now, I'm thrilled to be attending a new school that offers a broader range of courses and extracurricular activities. The campus is beautiful, and the students and faculty are incredibly friendly and welcoming. It's safe to say that my transition to this new school has been smooth and enjoyable.
As for my current mood, I'm feeling optimistic and eager to explore new opportunities. I'm excited to meet new people, learn new subjects, and participate in various activities. The prospect of joining new clubs and participating in events is thrilling, and I can't wait to see what the future holds.
Looking forward, I have high expectations for myself and my academic journey. I plan to take full advantage of the resources and opportunities available at my new school to achieve my goals.
