根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
In spite of so many years of education behind us, can we confidently say we understand what it feels like to be a teacher?
The biggest misunderstanding about teaching jobs is that anyone can be a teacher. In fact, the truth is far from it. 1 They also know the teaching theory well. They should know how things should be taught and how one can be inspired to learn. Also, they need to have an idea about classroom management and students’ psychology（心理学）.
Now it can be really annoying for a teacher if someone says teaching is one of the easiest jobs around, because everyone just needs to be taught for a few hours a day. 2 However, teachers work longer to come up with ways to make the knowledge appear more interesting to students and help them learn better.
3 And this is a big reason why more people decide to choose teaching as a career. However, good teachers choose to make good use of the break, by enrolling (注册) themselves for workshops on teaching, classroom management, and related things.
All teachers are not the same, as against what is widely believed. 4 Every teacher is different and has a different approach（方法）to teaching.
5 A teacher has meetings to attend, and is responsible for (对……负责) organizing school events. An important duty of a teacher is to prepare the progress report of each student and discuss it with his or her parents.
In a word, teachersspan> ought to be respected for what they do, and we should never forget their great contribution（贡献）to our success in life.
A. A teacher has many things to do rather than just teach.
B. It is true that teachers get a lot more holidays than others.
C. A good teacher is one who motivates students to overcome challenges.
D. To begin with, teachers are people who perform well in their fields of study.
E. A statement that is true for one teacher is not necessarily true for the others.
F. And common people even believe teachers are probably overpaid when their days end at 3 pm.
G. These teachers give all they can to create an ideal learning environment for their students.
