解决方法如下：

1. 导入BeautifulSoup库：

from bs4 import BeautifulSoup

2. 读取HTML内容：

html = '''



Hello, World!
This is a sample paragraph.
This is another paragraph.



'''

3. 创建BeautifulSoup对象：

soup = BeautifulSoup(html, 'html.parser')

4. 使用find方法查找包含指定文本的标签：

tag = soup.find(text="This is another paragraph.")
if tag:
    print(tag.parent)
else:
    print("找不到包含指定文本的标签")

完整代码示例：

from bs4 import BeautifulSoup

html = '''



Hello, World!
This is a sample paragraph.
This is another paragraph.



'''

soup = BeautifulSoup(html, 'html.parser')

tag = soup.find(text="This is another paragraph.")
if tag:
    print(tag.parent)
else:
    print("找不到包含指定文本的标签")

输出结果：

This is another paragraph.
