学习了生词，回过头再听几遍，争取每句话都听懂，没听出来的对照下面的英文原稿。
Are worms the heroes we didn't know we needed? Silent, slimy and wriggling, you might think that worms are good for nothing except bait on the end of a fishing rod. However, there is more to the humble worm than meets the eye.
The British naturalist Charles Darwin said that no other animal has "played such an important part in the history of the world as these lowly organised creatures". They have lived on Earth for 600 million years and have even survived five mass extinctions. So, what do worms do that is so great?
Earthworms literally move the earth, and this is why farmers love them. As they travel, they aerate the soil by loosening, mixing and oxygenating it, which increases the ground's capacity to hold and drain water. They are effectively a small but very efficient plough. But it's not just earthworms that deserve praise.
In 2022, a group of scientists at the Margarita Salas Center for Biological Research isolated enzymes found in wax worm saliva which are plastic-eating. These can break down polyethylene, a very common plastic that normally degrades over many years. It's hoped that by producing these enzymes on an industry-level scale, we will have a more environmentally friendly way to reduce plastic pollution.
And worms are even inspiring the building industry. Bloodworms are small sea creatures which burrow into the mud of the ocean floor. Scientists at the University of California, Santa Barbara have been studying their jaws, which are made up of 10% copper proteins and are so strong that they last the worm's entire five-year lifespan. Because of this research, engineers may start using the jaws as inspiration for the design and manufacture of materials like concrete.
So, next time you see a worm, show it a little respect. They really are changing the world!
