This video is proposing 9 practice tasks for the FIRST question in the speaking section of the TOEFL IBT. You will also find sample responses for each of the tasks. These were included with the original CD. If anything, these samples can teach you the format of a good response. But don't let yourself be discouraged by the quality of their language and content. You will only have 15 seconds to prepare and I'm sure these guys took hours to write those samples... So the judges don't expect this kind of quality. But what they do expect is the level of organization they display. So when preparing your response, make sure you respect the following pattern
1: A Clear Topic Statement
2: 2 reasons to hold your opinion
3: Details and examples for each of your reasons.
4: A concise concluding statement... (example: those are the reasons I believe... kind of thing)
With that in mind, you should be able to get a good score for this question at least. That is if your grammar and vocabulary is good... of course.
