High-level Response: Listen to

Rater Comments
This speaker speaks quite naturally and uses stress and intonation well, which helps the listener to follow and understand his response easily. For example, the way he says, " it"s so much easier ," helps to make his point about the ease of using a car instead of the bus. He is also able to use rather advanced structures to effectively make this comparison: " compared with the other transportation devices, it"s so much faster. " (Note that "device" is an incorrect word choice here.) The speaker does hesitate and repeat words at times, but this is not overly distracting. He develops his response well, using the personal example of how long it takes him to get to the movie theater using both modes of transportation.
Mid-level Response: Listen to

Rater Comments
This speaker provides several good reasons and details to justify his choice of the subway as the most efficient. In terms of content, this is a strong response. However, the speaker is hard to follow at times. In contrast to the high-level response, which used stress patterns effectively to convey meaning, this speaker speaks in a fiat tone, pausing infrequently and at odd places. This means that the listener has to make an effort to separate his ideas and understand what he is saying. Some mistakes in pronunciation (" scheduled "), misused words ("electronic" instead of "electricity"), and some long hesitations also prevent this response from reaching the high level. [听力原文]
