“Solid”和“sturdy”这两个英语单词都表示坚固，但它们侧重的方面略有不同。“Solid”更强调物质的致密、坚实和完整性，通常用来形容物体的密度和结构的紧凑程度；而“sturdy”则更强调物体的结实、耐用和能够承受压力或冲击的能力。 简单来说，“solid”指“结实紧密”，而“sturdy”指“结实耐用”。

让我们来看一些例句来更好地理解它们的区别：

• Example 1 (Solid): This table is made of solid oak. (这张桌子是用实木橡木做的。) Here, "solid" emphasizes the density and quality of the wood, indicating it's a single, dense piece, not hollow or made of compressed materials.

• Example 2 (Sturdy): This sturdy chair can hold up to 300 pounds. (这把结实的椅子能承受300磅的重量。) "Sturdy" highlights the chair's ability to withstand weight and pressure. It focuses on its durability and strength.

• Example 3 (Solid): He gave me a solid piece of advice. (他给了我一个很实在的建议。) In this context, "solid" means reliable, dependable, and trustworthy, highlighting the quality and substance of the advice.

• Example 4 (Sturdy): The little boy built a sturdy tower out of blocks. (这个小男孩用积木搭建了一个结实的塔。) Here, "sturdy" describes the tower's ability to stand tall and resist collapse, emphasizing its resistance to external forces.

虽然这两个词有时可以互换使用，但细微的差别还是存在的。 选择哪个词取决于你想强调物体的哪个方面。 记住它们的区别，你的英语表达将会更加精准！
