Clovers are lovely green plants that grow close to the ground. They can be found in most parts of the world. Typically, each stem of the plant has three green leaves at the top. However, genetic differences sometimes cause an extra leaf to grow, creating the rare four-leaf clover. Because the chances of finding one are slim, many people believe that finding a four-leaf clover brings good luck. This fourth leaf is often smaller than the other three leaves. Clovers with five or more leaves have also been documented, with the current world record holder boasting an impressive 63 leaves on a single stem.
三叶草是靠近地面生长的可爱绿色植物。它们几乎遍布于世界各地。一般来说，每株三叶草的茎部顶端有三片绿色的叶子。然而，基因差异有时会导致多长出一片叶子的情况，形成罕见的四叶草。由于找到四叶草的机率渺茫，许多人相信找到四叶草可以带来好运。这第四片叶子通常比其他三片叶子小。拥有五片或更多叶子的三叶草也曾被记载过，目前的世界纪录保持者以拥有一株惊人地在单一茎上有著六十三片叶子的三叶草为傲。
