4、 阅读理解。
One midsummer day, biologist Andrew Parker knelt in the baking sand of an Australian desert and gently placed the right back leg of a small lizard into a dish of water. The small lizard that has learned to survive in the extreme heat—has a secret that attracted Parker. “Look!” he shouted. “Its back is completely drenched!” In less than a minute, water from the dish had traveled up the lizard’s leg, across its skin, and into its mouth. It was drinking through its foot. The lizard can also do this when standing on wet sand. Parker had come here to solve the riddle of how it does this, with a specific purpose in mind: to make an object to help people collect water in the desert.
Parker is a leading scientist in the field of biomimetics*—applying designs from nature to solve problems in engineering, materials science, medicine, and other fields. His studies of the body coverings of butterflies and beetles have led to brighter screens for cell phones.
The work of Parker is only one part of a growing global biomimetics movement. Scientists around the world are trving to copy a wide variety of nature’s design secrets. In the United States, researchers are looking at the shape of humpback whale fins to help wind turbines* produce more electric energy. The shape of the body of a certain fish has inspired* designers at Mercedes—Benz to develop a more efficient car design. By analyzing how termites — a kind of insect keep their large mounds’ at the right temperature and humidity, architects in Zimbabwe have built more comfortable buildings. And in Japan, medical researchers have developed a painless needle that is similar in shape to the proboscis* of a mosquito.
Perhaps, one of the most useful applications of biomimetics is the robot. Professor Ronald Fearing is creating a tiny robot fly that can be used in surveillance or rescue operations. Although it will be years before his robot fly can perform anything like an actual fly. Fearing is confident that over time he will close the gap between nature and human engineering.
Nowadays, the gap with nature is gradually closing. Researchers are using more powerful microscopes, high-speed computers and other new technologies to learn more from nature. A growing number of biomimetic materials are being produced. And although the field of biomimetics has vet to become a successful commercial industry, it has already developed into a powerful tool for understanding nature’s secret.
1. Andrew Parker went to the Australian desert to ________.
A study the diet of lizards B. learn how lizards collect water
C. catch and bring back a lizard D. prove that lizards don’t need water

A. wet B. dry C. hot D. cold
3. The study of termite mounds has inspired people to ________.
A. improve wind turbines B. invent a painless needle
C. build more comfortable buildings D. develop a more efficient car design
4. What’s the purpose of writing this passage?
A. To give us examples of some biomimetics designs.
B. To show us the rapid development of biomimetics.
C. To tell us scientists are working on biomimetics.
D. To introduce some great scientists working on biomimetics.
