A cactus (仙人掌) can store water when it rains. It then uses this water during the long dry season. The small needles on some kinds of cacti may number in the tens of thousands. These sharp thorns (刺) protect the cactus. They also form tiny shadows in the sunlight that help keep the plant from getting too hot. Other plants are able to live by dropping their leaves. This cuts down on the evaporation of their water supply in the hot sun. Still other plants survive as seeds（种子）, protected from the sun and heat by tough seed coats. When it rains, the seeds sprout quickly, bloom and produce more seeds that can withstand a long dry spells(一段时间). Some plants spread their roots close to the Earths surface to quickly gather water when it does rain. Other plants, such as the mesquite(豆科灌木), have roots that grow 50 or 60 feet below the ground to reach underground water supplies. ( )46.
