阅读文章,把方框中代表句子的字母A、B、C、D、E填到文章中划线部分的相应位置上。
A. If the new species (物种) is too strong or uses too much of the resources (资源) in the habitat.
B. We often talk about how important it is to take good care of ourselves and our planet
C. When farmers cut down trees, tigers can no longer hide and hunt
D. Steve says that we can help by creating more space for animals and plants
E. A species can become endangered for different reasons
                                                          Are we endangered?
     Steve Jones is an environmental expert who tries to keep animals and plants from becoming endangered.
"We are not alone in the world. We human beings could not survive (生存) without all the plants and animals
around us. 1           , but we don't always do as we say," Steve says as he takes us on a tour of Green Park
in Birmingham. Many of the earth's plants and animals have already died out, and several other species are
endangered. If we want to live a better life and have a bright future, we must learn to act in ways that do not
harm other living things.
     If we know more about what causes endangerment, we may be able to take measures (采取措施) before
it is too late. 2           . Animals and plants must have a habitat, or home, which is comfortable and clean,
and where there is enough food and other resources. They are all used to their environment; that is, they have
learnt how to live successfully in their habitat. When the habitat of a species is changed or destroyed, the
animal or plant had to either adapt to the change or find a new home. If this is not possible, the species becomes
endangered. If a new species arrives, the animals and plants of the habitats must change again. 3          , some
of the original (原始的) species may become endangered. A species may also die out if humans or other animals
use too much of a plant or kill too many animals.
     The good news is that there is a lot we can do to help. First of all, we need to learn more about animals,
plants and the environment. Experts tell us that we need to think about what we can do to keep animals and
plants from becoming endangered. 4           :"You can plant a tree or build a birdhouse. It is simple but useful."
Steve also wants us to think about what we do: "Please don't pollute the environment." If we find out more
about what we should do, we can help Steve and others like him keep. animals and plants and ourselves from
becoming endangered.
