We sometimes call the lion “the king of the jungle (丛林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the   1  food chain (食物链).

In the sea, the shark is one of the animals at the  2  of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.

What is at the top of the world’s food chain?  3  are! We are not the biggest or fastest, but we are the   4  We could not run faster than cheetahs (猎豹),  so we  5  cars and now we can move the fastest. We could not  6   better than lions, so we invented guns (枪). Now we can hunt the best.

People’s inventions are clever, but they can be dangerous, too. For example, people invented  7 , and now they make the air and rivers dirty. This can make   8  changes.
