阅读下列短文，从文后各题所给的四个选项中选出一个最佳答案。
What does the word ecology mean It was 76 by Ernst Haeckel, a German biologist. He joined two Greek words: oikos, meaning “house,” and logie, meaning “the study of”. Together they mean “the study of the house.” The “house” Haeckel had in mind is our 77 , Earth. Earth is home for all living things—humans, animals, plants, and even 78 microbes.
To study a house is to learn how its residents（居民）use it. An ecologist is a scientist who studies the 79 between organisms （生物）and their environment. The environment is an organism’s surroundings. It may 80 water, gases, rocks, and temperature.
Ecologists also study the balance of 81 the environment while protecting it.
An ecologist once asked a boy 82 he thought it meant to protect the environment.
The boy said, “You go into the 83 and look for somebody who wants to cut down a tree. You take away his axe. You tell him about how 84 trees are. You say they are good for natural beauty, saving soil, and giving shelter to birds and other animals.”
“Good answer,” said the ecologist, “ 85 it may not be easy to find a woodcutter to talk to. Also, remember that sometimes it’s 86 to cut down a tree. If we cut down too many trees, the forest will disappear. 87 we don’t cut down any trees, we won’t get any resources from the forest. We have to find the right 88 .”
“I get it,” the boy said. “We need the forest’s 89 for wood and paper or we might not have desks or notebooks for school.”
“Exactly—and school is a good place to learn about ecology”, 90 the ecologist. “Then you will know how to protect the natural environment.”

Bats tend to live in dark and wet places. There are all 91 of viruses. Bats always live in groups. Therefore the viruses can have large “playgrounds’’ to evolve (进化) and become 92 ariants (变体). Bats are mammals (哺乳动物), just like humans. Our similar genes (基因) make it 93 for us to become infected with the same viruses.
When bats fly, their body temperature can reach as 94 as 40℃. This temperature can kill weak viruses, but stronger 95 will survive (存活) and continue to evolve. Bats have special immune (免疫) systems 96 allow them to live with viruses without getting sick. Since they can fly, bats can spread viruses farther and more easily than other animals.
Although wild animals carry many diseases, it doesn’t mean that we should view them 97 evil. Each species has a role in the ecosystem (生态系统) and all of them are important for keeping a good ecological balance. The 98 we should learn from virus outbreaks is to respect and 99 animals and to live in harmony with them, instead 100 hunting, killing, or eating them.
