1. 释义:

"As to" 是一个英语短语,通常用于引导一个关于前面话题的新的或具体的讨论点。它等同于 "关于" 或 "至于",用来引出对某个问题或主题的看法、解释或决定。在句子中,"as to" 通常置于主句之后,用来引导一个从句。

2. 用法:

- 引导观点或意见:例如,"As to the proposal, I think it's worth considering."(至于这个提议,我认为值得考虑。)

- 表示对比或转折:例如,"We agree on the first point, but as to the second, we have different opinions."(我们对第一个点达成一致,但至于第二个点,我们有不同的看法。)

- 引导决定或计划:例如,"As to the meeting, we'll have it at 3 pm tomorrow."(关于会议,我们将在明天下午三点举行。)

3. 同义词辨析:

- "Regarding": 这个词也表示“关于”,但通常用在正式或书面语境中,如 "Regarding the matter, we need further discussion."(关于这个问题,我们需要进一步讨论。)

- "In regard to": 比 "as to" 更显正式,如 "In regard to your question, I will provide an answer later."(关于你的问题,我会稍后给出答案。)

- "With respect to": 常用于学术或专业环境中,如 "With respect to the experiment, the results were inconclusive."(关于实验,结果并不明确。)

- "Concerning": 这个词语气较强烈,暗示某种问题或挑战,如 "Concerning the budget, there seems to be a significant shortfall."(关于预算,似乎存在显著的短缺。)

4. 注意事项:

- "As to" 不宜用于句首,因为它通常引导一个从句,而从句不常置于句首。

- 它可以与多种动词搭配,如 "think", "believe", "decide" 等,表达不同的含义。
