Book 2-Unit 1 An expressive English lesson

Analyze the following text

1、填空题：
  1 It is a common knowledge that education plays an important role in our lives. The utmost level of education is undoubtedly to have a university degree. However, not every university may   meet your expectations. In order to state that you are a graduate of a good university, there should be some requirements to be met. In my opinion, a good university should have qualified teachers, technologically   adequate buildings and many facilities for students.​      2 First of all, it must have enough qualified teachers for each course. Qualified teachers should   have adequate teaching skills in their subjects. Without adequate teaching skills, it will be difficult for the teacher to transfer his/her knowledge to the students. Also, as a person, the teacher should have proper personalities, that is, a teacher should be kind, supportive and   understanding to his/her students. Otherwise, they may be disliked. So, good teachers are indispensable for a good university.​      3 Secondly, a good university must have many buildings with adequate high technology facilities with students. The classrooms must be large enough and  well–equipped. A small classroom or a classroom without  technological supplies such as the internet or television will certainly demotivate students. In addition, libraries should have enough books and materials for students. This is very important to do research for students' studies or assignments. All these above  considered, technologically developed buildings are necessary for a good  university education.​     4 Finally, a good  university should have many facilities for students. For example, there  must be enough sport centers and cafes for students to spend their time.  Since students spend most of their time studying at school, they need a place  to rest and chat with their friends.​ In addition, students sometimes need to get over their stress spending time in a sport center. Thus, beside academic study, a good university should provide social opportunities to its students.​     5 In conclusion, universities are places where students spend the most important stage of their lives. Universities should support the learning process with qualified teachers, technologically adequate buildings and many social facilities. Students should become familiar with all these characteristics so that they can choose a good university, which will affect their future.​Question:​Identify three parts of the essay: introductory paragraph, body paragraphs and concluding paragraph. ​​​‏​
