Problem:Article: The capsized accident which happened in Yangtze River on June 1st, 2015 shocked the whole country.There are so many people related to this accident.Zhang Shunwen, the captain of the vessel , has been probably the person being mostly discussed now. Born in 1963, Zhang has been working on this ship for 35 years and became captain of it in 2007.Until the accident, Zhang was regarded as an effective captain and his experience as a sailor was flawless with numerous awards. Zhang Shunwen said the wind was coming from the South, and the wind then was about three to four grade.He first tried to ride the ship northward on the leeside in an effort to counter it with the vessel's speed.However, the wind suddenly gathered speed and he lost control of the ship."We couldn't fend off the wind even if we made a full left turn." he said. Zhang escaped alive and is under watching by police, although he has not yet been accused of any wrongdoing. Every person has his opinion toward this kind behavior of police. Some of them think of it to be improper because the captain himself is also a victim in this accident, what's more, his wife, who also boarded on this boat, remains missing now. While others are in support of this action, to them, it is the captain who should shoulder the responsibility. For me, I agree with the former. Because the captain has made every effort to deal with the accident.
