在英语中，“虽然但是”这一结构通常可以通过“although”或“though”（表示“虽然”）与“yet”或“but”（表示“但是”）的结合来表达。以下是一些常见的表达方式：
Although + 句子, yet + 句子：
- Although he was tired, yet he kept on working. 虽然他很累，但他还是继续工作。
Although + 句子, but + 句子（注意：虽然“although”和“but”在严格意义上不应在同一句子中连用，但在非正式或口语中有时会见到这种用法）：
- Although it was raining, but he still went out. （更正式的表达应为：Although it was raining, he still went out.） 虽然下着雨，但他还是出去了。
Though + 句子, yet/but + 句子：
- Though he is rich, yet he is not happy. 虽然他很有钱，但他并不快乐。
- Though I wanted to stay, but I had to leave. （更正式的表达应为：Though I wanted to stay, I had to leave.） 虽然我想留下，但我不得不离开。
在正式写作中，推荐使用“although”与“yet”的搭配，或者单独使用“although”并在后续句子中用逗号隔开（省略“yet”或“but”），以保持句子的流畅性和正式性。例如：
- Although he was very tired, he still managed to finish the race. 虽然他非常累，但他还是设法完成了比赛。
总的来说，“although”和“though”后面跟从句，“yet”或“but”（在非正式场合下）用来引导表示转折的主句，这样构成了英语中表达“虽然但是”的结构。
