在使用编程语言编写代码来按主题和日期范围选择新电子邮件的解决方法将根据你使用的编程语言而有所不同。下面是一个使用Python和IMAP库的示例代码，用来从电子邮件服务器中选择满足指定主题和日期范围的新邮件：

import imaplib
import email
from datetime import datetime, timedelta

def select_emails_by_subject_and_date_range(server, username, password, subject, start_date, end_date):
    # 连接到IMAP服务器
    mail = imaplib.IMAP4_SSL(server)
    mail.login(username, password)
    mail.select("inbox")

    # 构建日期范围查询
    start_date = (datetime.now() - timedelta(days=start_date)).strftime("%d-%b-%Y")
    end_date = (datetime.now() - timedelta(days=end_date)).strftime("%d-%b-%Y")
    date_query = f'(SINCE "{start_date}" BEFORE "{end_date}")'

    # 构建主题查询
    subject_query = f'SUBJECT "{subject}"'

    # 组合查询条件
    query = f'({date_query} {subject_query})'

    # 搜索符合查询条件的邮件
    result, data = mail.search(None, query)

    # 获取匹配的邮件ID列表
    email_ids = data[0].split()

    # 遍历邮件ID，并打印邮件主题
    for email_id in email_ids:
        result, data = mail.fetch(email_id, "(RFC822)")
        raw_email = data[0][1]
        email_message = email.message_from_bytes(raw_email)
        print("Subject:", email_message["Subject"])

    # 关闭连接
    mail.logout()

# 示例用法
server = "your_email_server"
username = "your_username"
password = "your_password"
subject = "your_subject"
start_date = 7  # 选择最近7天内的邮件
end_date = 0  # 选择过去24小时内的邮件

select_emails_by_subject_and_date_range(server, username, password, subject, start_date, end_date)

请注意，这只是一个示例代码，你需要根据你的具体需求进行适当的修改。
