英文小作文：

Cicadas and their shells are symbols of summer in many cultures, and they have fascinated people for centuries. To me, cicadas are a reminder of nature"s rhythm and the passage of time. As they emerge from their nymph stage and sing their song, we can feel the warmth of summer and the joy of new life.

Their shells, which are often collected and used in traditional Chinese medicine, are also a testament to their lifecycle. These exoskeletons, which once protected the nymphs, now serve as a reminder of their past and a keepsake of nature"s beauty.

Cicadas also teach us about resilience and perseverance. Despite their harsh environment and challenging lifecycle, they emerge from their shells to sing their song and contribute to the beauty of nature. Similarly, we can learn from their example to face challenges with courage and persistence, knowing that with time and effort, we too can emerge as better versions of ourselves.
