Example Input: Article: I moved to this area seven years ago. For years I have had noisy neighbours. Ever since I moved into this flat, I've had to put up with noise during the night. I decided I'd had enough and I've been looking for a new flat since the beginning of the year. I haven't found anything till now. Every week I go to the estate agent's office, but it's the same story. "I might have something by the end of the week" he says, or, "Wait till next week. I think I might have a few flats by then." I've seen a few flats during my search, but I don't like any of them. One flat I saw has been empty for two years. "It's got a busy road on one side and a railway on the other!" I said loudly, "I want peace and quiet." Last week I visited the agent again. "I won't leave till you show me something," I said. "I've got just the flat for you." I went to see it and I was frightened. "But it's next to a cemetery!" I cried. "But you won't have noisy neighbours," my agent said. "It's exactly right for peace and quiet!"

No traditional classroom can compare with it. We give each lesson according to the students' interest and their strong and weak points, "said Joel. Klein, the school's headteacher, "We're looking for a new way that interests students. " Students enjoy these math lessons, especially lessons with video games.

Caleb Deng had to answer the question: What is 5+(6x3)? He _ on paper quickly because there was just a minute left to play. "I was right, "said Deng, 14, as he ended the game with a high score .

Example Input: Article: I have a good memory of my grandfather,Jack. He was sitting in his armchair in the front room. I sat next to him. We were reading aloud,our heads bent over the page in front of us,a finger marking the words;separated by seven decades,brought together by words. It's a common scene in British families;however,in our case,the usual order of things is reversed .Granddad had been blind since I was tiny,so I was reading to him.When reading aloud,people usually read something that's of interest to the listener. So I didn't read children's books;I read the sorts of things Granddad liked to hear about. Much of the vocabulary in Granddad's reading material was far beyond me. When I met unfamiliar words,I'd spell them out. Granddad would help me. It must have been painful for him to hear news;but he never hurried me along or complained. Our reading wasn't really about getting knowledge. It was a way for us to spend time together. My grandfather wasn't always blind. He had been a good carpenter .The first Christmas of my parents' marriage,he built my mother a bookcase,which now belongs to my son Jonah,providing a link between four generations. I was a fortunate child;I spent a lot of time with my grandfather,and he opened the world to me in a particular way. Reading was our way of building a relationship that has had a lasting effect on me. In the school holidays,I sometimes accompanied him on trips to the seaside with the local association for the blind. This might seem strange,but I felt that my personal value was realized because I could finally do something for Granddad. A decade later,I found a position in a nursing home,which reminded me of my early experiences;reading to senior citizens was a connection back to Granddad. More than simple conversation,reading aloud is a connection between two individuals and it can have a big emotional effect on elderly people.
