以下是雅思口语评分标准的4个维度：
1. Fluency and coherence
2. Lexical resource
3. Grammatical range and accuracy
4. Pronunciation
下面我们逐条来分析：
Fluency and coherence
Band 7:
1) Speaks at length without noticeable effort or loss of coherence
2) May demonstrate language-related hesitation at times, or some repetition and/or self-correction
3) Usesa range of connectives and discourse markers with some flexibility
without noticeable effort：表明你在表达的时候没有明显的困难，这就需要你有更少的停顿或犹豫；
Usesa range of connectives and discourse markers: 有一定灵活性地使用一系列连接词和语篇标记；
连接词这个概念大家都比较清楚，但我考了那么多次，哪怕是我考到9的那次（突然骄傲），用的连接词就只是以下这些：“and, also, so, because, but, although, before,after, when”等非常简单的连接词，为什么不用“furthermore, moreover, nevertheless”这些看起来很高端的连接词呢？后面词汇的时候我会说到。
有同学对语篇标记比较疑惑，但其实我们在不经意间就已经使用了很多语篇标记，这里我举几个例子：
Part1: “Well, Chinese people nowadays are pretty well-off,so...”
Part2: “… Anyway, we didn’t stay there for too long...”
Part3: “…You know, China is stilla developing country, so...”
这里的“Well,anyway, you know”就是3种表示不同功能的语篇标记，如果大家对此还有疑惑的话，可以剑桥在线词典上搜索“discourse marker”，里面会有更详尽的解释。
Band 7:
1) Usea range of complex structures with some flexibility
2) Frequently produces error-free sentences, though some grammatical mistakes persist
简单的从句，比如：
描述人的时候多用who或that：He’s kind and generous, who’s been actively involved in charity.
描述物品的时候多用which：This is one of my favorite books that I’ve read over and over again.
描述地点的时候多用where：It’s a great place where people can come together and enjoy their weekend.
用 “before, after, when”等连接词连接两个简单句的复合句：
He left before I could thank him.
It happened not long after he graduated from high school.
When I was a child, I used to share toys with my friends.
同时推荐：
给出更多样的时态，比如除了基本的“一般现在时态，过去时态，将来时态”等，可以多使用：
现在完成时态：We’ve known each other for over 20 years.
现在完成进行时态：I’ve been living here for a longtime.
虚拟语气：
第二条件句：If I were you, I would go there by bus.
第三条件句：If it wasn’t for the rain, we’d have arrived there on time.
等等；
同时尽量保证基础语法不出错，比如常见的代词，介词，主谓一致，过去时态的使用要保证准确；
接下来我们看Lexical resource，这也是很多同学非常头疼的一点。
1) Use vocabulary resource flexibly to discuss a variety of topics.
2) Uses some less common and idiomatic vocabulary and shows some awareness ofstyle and collocation, with some inappropriate choices
3) Uses paraphrase effectively
下面这些词汇大家可以着重记忆一下：
Very good→superb
Very bad→terrible
Very cold→freezing
Very rich→wealthy
Very happy→delighted
idiomatic vocabulary：习惯用语
我们先看几个短语：“take off, pick up, get alongwith, take part in, used to, get in touch with”。
大家觉得这些是idiomatic vocabulary吗？答案是：是的。因为它们都符合语言表达习惯，属于习惯用语。
这也是大家存在的一个误区，觉得只有类似：raining cats and dogs, cost an arm and a leg等idioms才符合7分的要求，因此疯狂囤积背诵类似的短语，完全不在意这些短语正确使用的语境，导致最后弄巧成拙，甚至闹出笑话。
因此建议大家先把基础的习惯用语的先用准确了，再去考虑在正确的语境下使用idioms。
举个例子：
我在2017年的一场考试中被问到了rainy days这个Part1的话题的时候考官问我：
Q: Do people take raincoats when they go out?
A: Well, the weather in Chongqing is quite changeable. I mean, it could rain out of the blue, so it’s kindof necessary to bring an umbrella when you go out.
在这里由于我在前面已经给了重庆的天气相当多变这个前提，因此后面的idiom “out of the blue”就有了语境的依托，这里表示suddenly就比较恰当了。
Awarenessof style：语体
我们来看一个例子：
We were obliged to return earlier than planned due to poor weather conditions.
We had to go back sooner than planned because the weather was so bad.
我们做一个小quiz吧，选出你认为对的搭配：
The government should pay attention in/at/to the air pollution.
Recently I’ve been busy in/with/about my study.
I gave/took/made a phone call to my friend.
The food in my hometown is very/extremely/really delicious!
我们来看正确答案：
The government should pay attention to the air pollution.
Recently I’ve been busy with my study.
I made a phone call to my friend.
The food in my hometown is really delicious!
另外从搭配的定义上来讲，是没有规律的，是人们的习惯用法，这也给大家的记忆带来了很大难度，下面这个系列是我推荐的比较好的积累搭配的书，大家百度即可下载：“English Collocations In Use”
use paraphrase effectively：转述
看下面这个例子：
Q: Do you like traveling?
A: Yes, I like traveling. I like to see different and unique parts of the world, like the Great Wall in China, and Ilike to meet people from different cultures too.
大家对比下面这个回答：
A: Yes, I love traveling! I really enjoy seeing different and unique parts of the world, like the Great Wall in China, and I like to meet people from different cultures too.
