+    <h1>李白《静夜思》赏析</h1>
+    <p><em>《静夜思》</em>是唐代诗人李白的经典诗作，它短小精悍，却蕴含着深深的思乡之情。</p>
+
+    <h2>原诗内容</h2>
+    <p><strong>床前</strong>明月光，<br>
+        疑是地上霜。<br>
+        举头<sup>①</sup>望明月，<br>
+        低头思故乡。</p>
+
+    <p> 在诗中，“床前”这个词被加粗（床前），起到了一定的强调作用，让读者首先注意到诗人所处的位置。<br>
+        而“疑是地上霜”这句诗，通过“霜”这个字形象地描绘出月光的皎洁清冷，仿佛地上结了一层霜，这种感觉通过简单的文字就传达给了读者。<br>
+        当诗人“举头①望明月”时，这里的上标数字①可以用来做注释标记，表示对“举头”这个动作可能存在的特殊解读或者引用来源等，明月成为了引发思乡之情的重要媒介。<br>
+        最后“低头思故乡”，诗人深沉地（用em标签表示情感上的强调）陷入对故乡的思念之中。</p>
+
+    <hr>
+    <p>这首诗虽然没有华丽的辞藻，但每一个字都像是经过精心雕琢，<strong>强烈地（用strong标签表示语义上的强调）</strong>触动着读者内心深处的思乡情感，成为了千古流传的佳作。</p>
