Read the following article and select the best answer. Article: My name is Hua Fei and I am a sporting robot of the 23rdcentury. I am an expert at high flying exercises. I jump from spaceships and as I fall I turn, dive circle and dance until I softly land as close as I can to the finishing line. Robot competitions in the 23rdcentury are truly a popular sport. Fans from all overprefix = st1 /Chinawatch their handheld TVs when a competition comes on. Last time I took part in the 78thOlympics on a flying island aboveBrusselsin the sky. I won the silver medal for my performance. This year I had the honour to be chosen again. I wanted to meet robots from other countries and explore ideas about sport. However, my programmer fell ill the week before we were going to leave. It was very painful for her and I felt very frightened. I no longer felt so confident that I would win. The day of the competition was rather cold for my legs and my special oil began to freeze. I paused before I jumped from the starting place on a little spaceship but then I began my performance. At the correct moment I tried to open my parachute but there was a problem. It only opened a little. Instead of flying softly to earth I began to fall faster and faster so that I could not turn, dive, circle or dance. My heart stopped beating as I landed heavily on a mountain covered with snow. This is why I am writing to you from my hospital bed with two broken legs and a fragile head. I did not win anything at the Olympics after all. I need the factory to build me two new legs and an even bigger head. Then I will be able to compete once more. Let's hope for greater success in the next Olympics! Question: What we know about Hua Fei is that he is_. - an experienced expert - a computer system - a flying spaceship - a sporting robot
(A).
a sporting robot

Read the following article and select the best answer. Article: Directions : Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B, C and D. Choose the one that fits best according to the information given in the passage When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks. But it was the boxfish that interested them. "We were surprised when this clumsy-looking fish became our model for designing an aerodynamic car",says Thomas Weber. He is the research and development chief for the car company Daimler. An aerodynamic design reduces wind drag and increases fuel efficiency. The boxfish may look clumsy, but it can start, stop ,back up and zigzag through the water with ease. And it does all this using surprisingly little energy. Daimler's bionic car is modeled on the fish's boxy skeletal system. Like the fish, the car is fast and drives easily. It's efficient too. The science behind nature-inspired inventions is called biomimicry . Biologist Janine Benyus came up with the term. As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature's best ideas. This month ,the Nature's 100 Best List will be revealed at the World Conservation Congress in Barcelona ,Spain. Benyus co-authored the list of nature inspired designs with economist Gunter Pauli. In Zimbabwe ,a country in southern Africa ,engineers designed energy-efficient buildings modeled on termite mounds . The buildings use vents to keep the air flowing and the temperature cool. A company in Atlanta ,US ,developed a self-cleaning paint modeled on the lotus leaf. When the paint dries ,it becomes bumpy ,just like the lotus leaf. Rain drops form on the bumps and roll off ,carrying dirt along with them. Nature has done billions of years of research. Only the best-designed products have survived. Companies owe Mother Nature a debt for all that... Question: Which is TRUE according to the passage? - In America a self-cleaning paint was modeled on the lotus flower. - Zimbabwe engineers learned from termites to create highly advanced heating systems. - After the boxfish ,many other ideas of new products are borrowed from nature. - Nature is a good source to turn to for improving technology.
(A).
Nature is a good source to turn to for improving technology.
