What is a garden path sentence?
【正确答案】：A garden path sentence is an awkward sentence that is initially interpreted with a different structure than it actually has. It typically takes quite a long time to figure out what the other structures are if the first choice turns out to be incorrect. Sometimes, people never figure it out. They have been “led up to the garden path”, and fooled into thinking the sentence has a different structure than it has. Reduced relative clauses quite frequently cause this feeling of having been garden-pathed.
One example of garden path sentence is “I placed the magazine Tom was reading in the reading room.” We tend to attach the elements “in the reading room” to the verbs preceding it. It seems that we were led down a garden path, but found out, at the end, that we took the wrong way. Then we have to correct our mistake by rereading the whole sentence.
