Part2的重要性
IELTS Speaking: the importance of part 2

如果Part2表现不太好雅思口语还能得高分吗？

Students often ask me what will happen if they do badly in part 2 of the speaking test. Is it still possible to get a high score?

Yes, in theory, it is still possible to get a reasonably high score (maybe band 7) if you do badly in part 2, but you would need to give excellent answers in part 3. In practice, candidates rarely recover from a bad part 2; I don't remember anyone who made a mess of part 2 but suddenly did a fantastic part 3.

My advice: You should consider part 2 as the core of your speaking test. It's your best chance to show how good your English is, and it's the examiner's best chance to listen carefully to your use of language. In fact, it's probably the point at which most examiners get a clear idea of what score to give you.

Students often worry that they need to use "complex structures" in the speaking test. But what is a complex structure?

This website explains the difference between simple sentences, compound sentences and complex sentences. You'll notice that compound and complex sentences are much easier than they sound! I'm sure you use them all the time without realising it.

Here's my advice: stop worrying about the need for "complex" grammar. Instead, focus on expressing your ideas well. As you explain your ideas in detail, you will naturally produce longer sentences which contain a variety of grammatical features.
