要实现点击按钮退出并重置时间，可以在按钮的命令函数中添加退出和重置时间的功能。以下是修改的代码示例：

import os
import random
import time
from fnmatch import fnmatch
import pygame
import tkinter as tk
from tkinter import *
import wave
import threading
import tkinter
import tkinter.filedialog
import tkinter.messagebox
import pyaudio

root = tk.Tk()
root.geometry("450x200+374+182")
root.title("英语单词")
english1 = "开始"

w = Label(root, font=('times', 20, 'bold'), text=english1)
w.pack()
timer_running = False


def word():
    path = "D:\MY python\English"
    lists = os.listdir(path)
    english = (random.choice(lists))
    global english1
    english1 = english.strip(".wav")

    time.sleep(3)
    basedir = r"D:\MY python\English"
    for root, dirs, files in os.walk(basedir):
        for file in files:
            english3 = os.path.join(root, file)
            if fnmatch(file, f"{english1}*.wav"):
                pygame.mixer.init()
                pygame.mixer.music.load(english3)
                pygame.mixer.music.play()
    w.configure(text=f"{english1}")
    w.after(100, word)


fileName = None
allowRecording = False
CHUNK_SIZE = 1024
CHANNELS = 2
FORMAT = pyaudio.paInt16
RATE = 44100


def record():
    global fileName
    p = pyaudio.PyAudio()

    stream = p.open(format=FORMAT,
                    channels=CHANNELS,
                    rate=RATE,
                    input=True,
                    frames_per_buffer=CHUNK_SIZE)

    wf = wave.open(fileName, 'wb')
    wf.setnchannels(CHANNELS)
    wf.setsampwidth(p.get_sample_size(FORMAT))
    wf.setframerate(RATE)

    while allowRecording:
        data = stream.read(CHUNK_SIZE)
        wf.writeframes(data)
    wf.close()
    stream.stop_stream()
    stream.close()
    p.terminate()
    fileName = None


def start():
    global allowRecording, fileName
    fileName = tkinter.filedialog.asksaveasfilename(filetypes=[('未压缩波形文件', '*.wav')])
    if not fileName:
        return
    if not fileName.endswith('.wav'):
        fileName = fileName + '.wav'
    allowRecording = True
    start_timer()
    lbStatus['text'] = '正在录音中...'
    threading.Thread(target=record).start()


def stop():
    global allowRecording
    allowRecording = False
    lbStatus['text'] = '录音已结束'
    stop_timer()


def closeWindow():
    if allowRecording:
        tkinter.messagebox.showerror('Recording', 'Please stop recording before close the window.')
        return
    stop_timer()  # 停止计时器
    root.destroy()


def tick():
    global sec
    sec += 1
    time['text'] = sec
    # Take advantage of the after method of the Label
    if timer_running:
        time.after(1000, tick)


def start_timer():
    global timer_running, sec
    sec = 0  # 重置时间
    timer_running = True
    tick()


def stop_timer():
    global timer_running, sec
    timer_running = False
    sec = 0
    time['text'] = sec


button = tk.Button(text="开始", command=word)
button.pack()
btnStart = tkinter.Button(root, text='开始录音', command=start)
btnStart.pack()
btnStop = tkinter.Button(root, text='结束录音', command=stop)
btnStop.pack()
lbStatus = tkinter.Label(root, text='录音已准备', anchor='w', fg='green')
lbStatus.pack()
root.protocol('WM_DELETE_WINDOW', closeWindow)
time = Label(root, fg='green')
time.pack()
root.mainloop()

在上面的代码中，我添加了一个 `stop_timer` 函数来停止计时器并重置时间。在 `stop` 函数中调用 `stop_timer` 函数来停止计时器。同时，在 `closeWindow` 函数中也调用了 `stop_timer` 函数来确保在关闭窗口之前停止计时器。
