Ⅲ. Read and complete the tasks.
The pan-Himalayan region is a good place to study plants. The Himalayas have very high mountains and very deep valleys. This makes it a special home for plants. Two-thirds of China's plants grow there, and many grow only in that place. By studying them, we learn about many China's plants.
Some plants there have cool ways to live in hard places. For example, snow lotuses cover their leaves like a little greenhouse to stay warm. Purple-blue flowers reflect(反射) sunlight to help look after their DNA. These show us how nature solves problems.
What is it like to work in the field? It is hard but exciting. In rainforests, we wear full hats to stop mosquitoes and ants. Once in Xizang, I tried to collect a small orchid(兰花). Suddenly, a group of local bees flew at me! The orchid's flowers looked like wasps' wings, so the insects thought I was hurting their friends. This experience taught me that plants can be very smart.
Why do I do this work? Because plants are important to us. Medicine, like artemisinin(青蒿素), came from plants and saved so many people. Hybrid rice started with wild plants and helped to end hunger. There are about 20,000 kinds of plants in the Himalayas. Who knows what else we might find? That hope gives me strength to continue my work.
A. Complete the table. No more than two words for each blank.
B. Answer the question.
How do plants protect themselves in the environment? Give an example.
