在英语中引出谚语有多种方法，以下是一些常见的技巧：

使用“as the saying goes”

意思是“常言道”或“正如有句谚语所说”，可以放在句首、句末或句子中间。例如：

“More haste less speed,” as the saying goes.

From my point of view, taking more physical exercises is a good way to solve these problems. Just as a saying goes: “only work no play makes Jack a dull boy.”

使用“There is a saying going like this”

意思是“有句谚语是这样说的”，通常放在句首。例如：

There is a saying going like this, “A friend in need is a friend indeed.”

使用“A proverb goes / says”

意思是“一句谚语说”，后面跟谚语的内容。例如：

A proverb goes, “Actions speak louder than words.”

使用“As a / the proverb goes / says”

类似于“as the saying goes”，但更正式一些。例如：

As a proverb says, “Where there is a will, there is a way.”

使用引号

如果谚语是特定的或需要强调，可以用引号括起来。例如：

“Actions speak louder than words.” （Proverb）

添加形容词或修饰语

有时可以在谚语前面加上一些形容词或修饰语来增加其正式性或特定性。例如：

An old Chinese proverb says, “井干方知水珍贵。”

根据具体的语境和写作风格，可以选择最适合的方式来引出谚语，以增强文章的表现力和说服力。
