Caves form over thousands of years,as water slowly dissolves (rock like limestone,creating amazing shapes such as stalactites(钟乳石)(which hang from the ceiling)and stalagmites(石 )which rise from the floor). Exploring caves,also called caving or spelunking,is an exciting activity,but it can be dangerous.Cavers must wear helmets and use headlamps,because it is completely dark inside. They also need to be careful not to damage the delicate（脆弱的)environment,as many cave 44 英语·课后分层作业 features take thousands of years to form.

Exploring this trench is one of humanity's final frontiers.The challenge isn't just to go down, but to survive,see,and collect scientific data.Early attempts used unmanned "landers"-heavy machines dropped on cables.In 2012,filmmaker James Cameron piloted the "Deepsea Challenger,”a specially designed submarine(潜艇)，to the bottom.It had a thick steel sphere to protect him from the pressure and powerful lights to pierce the darkness. The rewards of such missions are huge.Scientists have discovered strange life forms,like giant amoebas（变形虫)and translucent(半透明的)snails,that survive on chemical nutrients from the seabed,not sunlight.Studying these "extremophiles"helps us understand the limits of life,which might even inform the search for life on other planets.The rock samples collected help us understand Earth's geology and the movements of tectonic plates. Reaching the trench is a feat of engineering,but the true victory is knowledge.Each dive challenges our understanding of life and reminds us that even the most hostile(有阻碍的)places on our planet are full of surprises,waiting to be explored not by conquering,but by curious minds. (一)根据短文内容判断下列句子正(T)误(F)。 )1.The pressure at the bottom of the Mariana Trench is about 1,000 times stronger than at sea level. )2.All life forms in the deep sea depend on sunlight for energy. )3.Studying creatures from the trench helps scientists understand how life might exist on other planets.
