Ⅲ. Read and complete the tasks.
I am an ecologist. Today, I speak for the small creatures—the insects, worms, and other tiny life forms that most people ignore or even fear.
What would happen if insects disappeared? Within months, most life on land, including humans, would die. Plants would stop growing, too. Insects mean a lot to our ecosystems. If they are gone, everything else falls apart.
But here is the sad truth: we live on an unknown planet. Scientists have named only 1.8 million species. But the real number could be 10 million—or even more! We know less than 10% of life on Earth.
Worse still, we are causing the sixth great extinction. I use a word to help you remember the threats—HIPPO: Habitat loss, Invasive species, Pollution, Population growth, and Overharvesting.
If we do not stop this, half of all species may perish by the end of this century.
So what is my wish? To build an Encyclopedia of Life—a free, online database（数据库）of every known species on Earth. Everyone—students, teachers, scientists, and nature lovers—can use it to learn about the amazing life around us.
A. Match the words with the meanings.
()1. ecologist n. A. when a type of animal or plant no longer exists
()2. ignore v. B. a person who studies the relationship between living things and nature
()3. extinction n. C. to be gone
()4. perish v. D. to pay no attention to something or someone
B. Answer the questions.
()1. What does the underlined word “they” in Paragraph 2 refer to?
A. Lands. B. Humans. C. Plants. D. Insects.
()2. How many species have scientists named?
A. Ten million. B. One point eight million.
C. Ten percent of all species. D. Half of all species.
()3. What was the writer’s purpose of this talk?
A. To make people afraid of insects.
B. To sell his new book about nature.
C. To encourage people to discover and protect species.
D. To explain why humans are stronger than other species.
4. What is the writer’s wish? Why does he have this wish?

5. According to HIPPO, what can you do to help the writer realise his wish?

A. 1. B 2. D 3. A 4. C
B. 1. D 2. B 3. C
4. One possible version: The writer’s wish is to build an Encyclopedia of Life because he wants to protect all the amazing life around us.
5. One possible version: I can recycle paper and plastic.
