In the speaking test, examiners don't like it when students use phrases like:
在雅思口语考试中，考官不喜欢考生使用下列短语：

- That's a very interesting question...
- It is my personal opinion that...
- Personally, I would have to say that...
- I am of the opinion that it depends on...
- To be honest, I personally believe that...

These phrases sound unnatural, and it is obvious to the examiner that the student has memorised them.
这些短语听起来不自然。会让考官认为考生显然是在背诵。

So what should you do instead? My advice: just answer the question directly. Stop using memorised phrases, and just get straight to the point.
那应该怎样做呢？我建议直接回答问题。别用这些背诵过的短语，直接回答答案中的要点。
