有一个句子需要大家帮助翻译，谢谢了
The greater the size of the shaded area, the easier communication is; readers whose language and background differ from the writer’s can expect a more difficult task. On the other hand, if they are similar, the reader is likely to interpret the text without conscious effort. There are still dangers of misinterpretation, however: a careless reader may read into the text meanings that are not there, simply because his sense of having much in common with the writer is so strong. Such a reader assumes that the extent of the common ground is greater than it actually is.
