Imagine walking into a new classroom, filled with unfamiliar faces and a teacher who is about to be your guide through a new language. For many students in China, this experience is multiplied when they start learning English in the first grade. English is a challenging subject for beginners, but it opens up a world of opportunities.In the first grade, students are introduced to basic English vocabulary and grammar. They learn simple words like “hello,”“goodbye,” “yes,” and “no,” as well as basic sentence structures. One of the first activities they do is to create a simple “Hello, my name is…” card, which helps them practice their new vocabulary and introduces them to the concept of proper introductions.The classroom environment is designed to be engaging and interactive. There are posters with colorful pictures and words, and there are often games and activities that reinforce the lessons. One popular game is “Simon Says,” where the teacher calls out commands beginning with the word “Simon says,” and the students only follow the commands if they are preceded by “Simon says.”Despite the excitement, the first day of English class can also be daunting. Many students are worried about making mistakes and being corrected in front of their peers. However, the teacher reassures them that learning a new language is a process, and mistakes are a natural part of that process.Questions:1.Why is the first day of school exciting for students?2.What are some of the basic words and sentence structures that first-grade students learn in English?3.How does the classroom environment help students learn English?Answers:1.The first day of school is exciting for students because they are starting a new journey, meeting new classmates, and learning a new subject.2.Some of the basic words and sentence structures that first-grade students learn in English include “hello,” “goodbye,” “yes,” “no,” and simple sentence structures like “I am…,” “My name is…,” and “This is…”.3.The classroom environment helps students learn English by being engaging and interactive, with colorful posters and games that reinforce the lessons.三、完型填空（15分）Title: Human Education Edition Grade 7 English Mid-term Exam - Part 3: Cloze TestQuestion 1:Reading the following passage, choose the best word or phrase for each blankfrom the options given below.In the small town of Greenfield, the [1] of the library was always a topic of conversation among the residents.
