I probably wouldn't say " a newspaper writer", but "a writer for (The Times)", but the difference between a writer and a reporter is pretty self-explanatory. I would say a "writer" would be someone who just writes and a reporter would be someone who reports, and of course in the process writes the reports. Not all people who write for newspapers go out to various locations and file reports, some might stay in the office and write feature articles and such-like, but there may be a lot of crossover between the two. The actual jobs are not black and white.
I saw the phrase "newspaper writer" in the textbook we use in this school year. Here's the original text. What would you think of it? Do the sentences sound right? Do you think it was written a long time ago?
American genius is to be found in both the arts and the sciences. For example, Walt Whitman is well known as a great American poet. He was born on Long Island in 1819. At an early age he moved to Brooklyn. He was forced to go to work when he was quite young. However, he read a great deal. After teaching school for a while, he became a newspaper writer and finally the editor of the Brooklyn Eagle. Because of his opposition to slavery, he was fired from the newspaper. Then he went to work as a carpenter. During the Civil War, Whitman volunteered as a male nurse. He supplied the sick men with tobacco, took care of their wounds, and read the Bible to boys who were dying. After the war he worked for the government in Washington. His last days were spent in Camden, New Jersey, where he died in 1892. His best poems are contained in the volume called Leaves of Grass. When this volume was first published, many people criticized it. His poetry did not seem to be poetry at all. It did not rhyme, nor did it have a regular rhythm. He used the plain, simple words of everyday life. But some people were able to see the greatness of his poetry, which expressed his sincere love for other people. Whitman believed that humans and nature were both part of God. As a scientist, Thomas Edison is well known all over the world for his many inventions. Yet he had very little education. When his teachers criticized him for being stubborn and unwilling to learn, his mother decided not to give him a formal education. She encouraged his natural desire to read and experiment. By the time he was ten years old, he had developed a strong taste for chemistry and made himself a laboratory. His first inventions were begun during his adolescence. With a little money made from one of his inventions, he started his own manufacturing business in New Jersey. This later developed into a research laboratory. Here he perfected the incandescent lamp, which enabled electricity to replace gas. Here too, he first reproduced the sound of the human voice on an instrument called the phonograph. Constant experimentation played an important part in Edison's success. He slept very little and worked very hard. Both Whitman and Edison lived in New Jersey, but neither had much formal education. So hard work is an essential element in becoming a genius. For example, when people told Edison he was a genius, he answered, "Genius is 1 % inspiration and 99% perspiration."
