Lesson 3. Learning from Nature’s Genius Nature’s Inspiration
From flying birds to self-cleaning plants, the way nature ∙∙∙하는 방식 = how works fascinates us. fascinate: 매료시키다, 사로잡다 not only A but also B: A뿐만 아니라 B도 *A와 B에는 같은 형태의 말이 옴. 모방하다 Some people not only use nature but also imitate it 동사 동사 = nature to find solutions to their problems. to부정사의 부사적 용법(목적) Leonardo da Vinci (1452– 1519) was one such person. He wondered how birds could fly. 간접의문문의 어순: 의문사+주어+동사

Learning from a Bird: Moving Fast and Quietly The high-speed train was first made in Japan. 고속의 be+p. p. (수동태) But it had one problem. When the train entered a tunnel, the sudden increase in 시간 부사절을 이끄는 접속사: ∙∙∙할 때 터널, 굴 증가, 상승 air pressure created a very loud sound. cause: 초래하다 It often woke people up and caused headaches. = a very loud sound 등위접속사로 woke, caused를 연결 headache: 두통 A team of engineers tried to solve the problem, but to부정사의 부사적 용법(목적) they didn’t know how they could reduce the noise. 간접의문문의 어순: 의문사+주어+동사

Learning from Burrs: Inventing an All-Purpose Fastener 가시식물 만능의, 다용도의 잠금장치, 고정 장치 One day, a Swiss engineer, George de Mestral, was 과거진행형 hiking in the woods with his dog. stick to: ~를 ···에 붙이다 be+p. p. (수동태) On his way home, he saw that burrs were stuck to his on one’s way: ∙∙∙도중에 clothes and his dog’s hair. 어순: 의문사+주어+동사 He wanted to know 간접의문문의 how that happened. 알아차리다, 주목하다 noticed를 연결 take a closer at: ∙∙∙을 자세히 살펴보다 He took a look closer look at the등위접속사로 burrstook, and noticednotice: that (식물) 가시, 바늘 the ends of the burr needle: needles were not straight.
He wondered if he could apply that to make something useful. 의문사가 없는 간접의문문의 어순: If(∙∙∙인지 아닌지)+주어+동사 something+형용사: -thing으로 끝나는 말은 꾸며 주는 말이 뒤에 온다. After a lot of testing, he finally invented two new materials. One had many tiny needles like those of burrs and One. . The other. . : (둘 중) 하나는 …. 나머지 다른 하나는 …. the other had a hairy surface. When they were pressed together, they became = two new materials be+p. p. (수동태) a very good fastener. = two new materials
