종로 모의고사에 나온 문장인데요(3학년)A similar phenomenon occurs when the eye was still, ~여기서 was 가 쓰인게 적절한건가요?is 가 와야 하지 않을까요?문법공부안한지 오래됬는데;;주절이랑 종속절 시제관계가 어떻게되야하죠?혹시나 해서 전문을 올려드릴게요 그림이 있는지문인데 글만올릴게요When you look out the window of moving car, nearby objects appear to glide rapidly, but more distant objects appear to move more slowly. This phenomenon can be explained as follows. In Figure A, we see as eye viewing two objects at different distances. As the eye moves sideways, the distance which the images of the two objects travel across the retina are not the same. The image cast by Object B travels longer distance than that cast by Object A, which makes Object B, the nearer object, appear to move faster. A similar phenomenon occurs whenthe eye was still, and objects moved across the line of sight at equal speed as in Figure B. The image of Object D would travel further and faster across the retina than the image of Object C.
