好的，你需要使用 `tkinter` 中的 `ttk` 模块中提供的 `Combobox` 组件来实现下拉框。具体改动如下：

1. 首先需要在开头引入 `ttk` 模块：`from tkinter import ttk`

2. 然后将所有的 `Entry` 改为 `Combobox`，比如将 `self.date_entry = tk.Entry(master)` 改为 `self.date_entry = ttk.Combobox(master)`

3. 对于下拉框，需要设置可选项，可以使用 `values` 参数，比如 `self.date_entry = ttk.Combobox(master, values=["选项1", "选项2", "选项3"])`

4. 可以设置默认选中项，使用 `current` 参数，比如 `self.date_entry = ttk.Combobox(master, values=["选项1", "选项2", "选项3"], current=0)`

5. 最后需要设置字体和背景颜色，使用 `configure` 方法，比如 `self.date_entry.configure(font=("Arial", 14), background="white")`

修改后的代码如下：

from tkinter import ttk

class QueryWindow:
    def __init__(self, master):
        self.master = master
        master.title("查詢窗口")

        # 获取屏幕的宽度和高度
        screen_width = root.winfo_screenwidth()
        screen_height = root.winfo_screenheight()

        # 将窗口的大小设置为屏幕的大小
        master.geometry("%dx%d" % (screen_width, screen_height))

        # 下载按钮

        # 日期标签和输入框
        ri = datetime.datetime.now().strftime('%Y/%m/%d')
        self.date_label = tk.Label(master, text="日期:")
        self.date_label.grid(row=0, column=0, sticky=tk.W)
        self.date_entry = ttk.Combobox(master, values=["选项1", "选项2", "选项3"])
        self.date_entry.grid(row=0, column=1, sticky=tk.W)
        self.date_entry.current(0)
        self.date_entry.configure(font=("Arial", 14), background="white")

        self.line_label1 = tk.Label(master, text="线别:")
        self.line_label1.grid(row=1, column=0, sticky=tk.W)
        self.line_entry1 = ttk.Combobox(master, values=["选项1", "选项2", "选项3"])
        self.line_entry1.grid(row=1, column=1, sticky=tk.W)
        self.line_entry1.current(0)
        self.line_entry1.configure(font=("Arial", 14), background="white")

        self.line_label2 = tk.Label(master, text="点检表单:")
        self.line_label2.grid(row=2, column=0, sticky=tk.W)
        self.line_entry2 = ttk.Combobox(master, values=["选项1", "选项2", "选项3"])
        self.line_entry2.grid(row=2, column=1, sticky=tk.W)
        self.line_entry2.current(0)
        self.line_entry2.configure(font=("Arial", 14), background="white")

        # 查询按钮
        self.query_button = tk.Button(master, text="查询", command=self.query)
        self.query_button.grid(row=0, column=2, sticky=tk.W)

        # 结果标签和文本框
        self.result_label = tk.Label(master, text="")
        self.result_label.grid(row=2, column=0, sticky=tk.W)
        self.result_text = tk.Text(master)
        self.result_text.grid(row=3, column=0, columnspan=2, sticky=tk.W)
        self.result_text.configure(width=120)

        # 设置字体和背景颜色
        self.date_label.configure(font=("Arial", 14), background="white")
        self.line_label1.configure(font=("Arial", 14), background="white")
        self.line_label2.configure(font=("Arial", 14), background="white")
        self.query_button.configure(font=("Arial", 14), background="white")
        self.result_label.configure(font=("Arial", 14), background="white")
        self.result_text.configure(font=("Arial", 14), background="white")
