Here are three tips, one for each part of the speaking test.
下面有3个窍门,分别针对口语考试中的每个部分。

Part 1: stop and smile
第一部分:停止与微笑

For part 1 of the speaking test, you need to get used to giving short answers. Many students find it difficult to stop speaking, and the examiner is forced to interrupt. My tip is to give your answer then stop and smile, showing the examiner that you are ready for the next question.
在口语第一部分中,你要习惯简短回答。许多学生发现很难停住不说,然后考官不得不打断他们。我的诀窍是给出回答,停止,然后微笑,向考官表示你准备好回答下一题了。

Part 2: tell a story
第二部分:讲故事

In the context of speaking part 2, a story is simply a long example to illustrate a point that you have made. If you’re describing a person, for example, you could tell a story to illustrate why you like him/her. People find it easy to keep speaking for longer when they have a story to tell.
在第二部分中,故事是指用来说明你的观点的长例子。例如,如果你要描述一个人,你可以讲一个故事说明为什么你喜欢他/她。人们发现讲有故事可说时,很容易继续讲下去。

Part 3: include an ‘if...’ sentence
第三部分:使用if条件句

Adding a conditional 'if...' sentence might help your grammar score.
加入if条件句有助于提高你在语法方面的分数。
