写一个教师通讯录查询系统，要求有显示界面，可操作，有选项。系统里面有：1，显示所有教师 2，按姓名查询 3，按部门查询 4，打印青年教师 5，退出系统，这五个选项。并且生成模拟数据验证通讯录查询系统的准确性

好的，这个教师通讯录查询系统可以使用Python语言进行开发。下面是一个简单的实现：

# 导入模块
import random

# 定义教师类
class Teacher:
    def __init__(self, name, department, age):
        self.name = name
        self.department = department
        self.age = age

    def __str__(self):
        return '{}\t{}\t{}'.format(self.name, self.department, self.age)

# 生成模拟数据
names = ['张三', '李四', '王五', '赵六', '钱七']
departments = ['数学系', '物理系', '化学系', '生物系', '计算机系']
teachers = []
for i in range(50):
    name = random.choice(names)
    department = random.choice(departments)
    age = random.randint(25, 60)
    teachers.append(Teacher(name, department, age))

# 显示所有教师
def show_all_teachers():
    print('姓名\t部门\t年龄')
    for teacher in teachers:
        print(teacher)

# 按姓名查询
def search_by_name():
    name = input('请输入教师姓名：')
    results = [teacher for teacher in teachers if teacher.name == name]
    if len(results) == 0:
        print('未找到该教师')
    else:
        print('姓名\t部门\t年龄')
        for teacher in results:
            print(teacher)

# 按部门查询
def search_by_department():
    department = input('请输入部门名称：')
    results = [teacher for teacher in teachers if teacher.department == department]
    if len(results) == 0:
        print('未找到该部门')
    else:
        print('姓名\t部门\t年龄')
        for teacher in results:
            print(teacher)

# 打印青年教师
def print_young_teachers():
    print('姓名\t部门\t年龄')
    for teacher in teachers:
        if teacher.age <= 35:
            print(teacher)

# 主函数
def main():
    while True:
        print('1.显示所有教师')
        print('2.按姓名查询')
        print('3.按部门查询')
        print('4.打印青年教师')
        print('5.退出系统')
        choice = input('请输入选项：')
        if choice == '1':
            show_all_teachers()
        elif choice == '2':
            search_by_name()
        elif choice == '3':
            search_by_department()
        elif choice == '4':
            print_young_teachers()
        elif choice == '5':
            break
        else:
            print('输入有误，请重新输入')

if __name__ == '__main__':
    main()

这个系统中，通过定义一个教师类，生成了50个随机的教师数据，然后实现了按姓名、按部门查询，以及打印青年教师等功能。用户可以通过输入选项来使用这些功能。在主函数中通过一个while循环，不断接收用户的输入，直到用户选择退出系统。
