Let's discuss this topic. please share your opinions. 你认为保温杯有用吗？ 你怎么看？让我们来讨论这个话题吧！ 请说出你的观点。 I think thermal cups are important for me, especially in winter, because I like to drink hot water. The thermal cup can keep hot water warm for about six hours. I have three thermal cups. I always take it every time when I go on a business trip, go hiking or traveling. I remember that I forgot to take my thermal cup once when I was on a business trip. I felt very uneasy (I was not used to it不习惯), so I bought a new one at a local supermarket. I don't like to drink room temperature water or ice water, even in summer. I know that majority of the people in western countries drink tap water, ice water or (iced) coffee. I want to know do you think you need a thermal cup in your daily life? I look forward to hearing your thoughts. 我认为保温杯对我很重要，特别是在冬天，因为我喜欢喝热水, 它可以让热水保温大约6个小时。我有三个保温杯，我每次出差，徒步或旅行，总是带着它。我记得有一次出差时我忘记了带保温杯，我很不习惯，然后去当地的超市买了一个新的。即使在夏天我也不喜欢喝常温水或是冰水。 我知道大部分西方国家的人喝自来水，冰水或咖啡。我想知道，你认为在你的日常生活中，你需要一个保温杯吗？我期待听到你的想法。 说出 literally translates to "speak/say out." But it is not very natural in English. "I expect to hear..." sounds a bit forceful in English. It sounds like an order :) . Instead, you can say : I look forward to hearing ... / I am keen to hear ...
