大致上符合我们习惯对于听力能力的划分，不同的是官方的能力划分上，把22以上到30 都规划到了一起，但其实22 到30 之间还可以有一个25 的断点。
即以下我们会从 20 以下//21-25// 25-28+ 3个梯队来说下听力部分的提分方案。
Test takers who receive a Listening section score at the High-Intermediate level typically understand the main ideas and important details of conversations and lectures that take place in academic settings. 能听懂主要信息和重要的细节
对于 22+ 的导语部分：
Test takers who receive a Listening section score at the Advanced level typically understand conversations and lectures that take place in academic settings. 没有了17-21 阶段的“主要信息”的限定修饰， 22+ 的同学，就是所有的信息都能听懂了
Test takers who score at the High-Intermediate level typically can
■ Understand main ideas and explicitly stated important details that are reinforced (by repetition, paraphrase, or indirect reference).
■ Distinguish main ideas from other information.
■ Keep track of information over an extended portion of an information-rich lecture or conversation, and recognize multiple, possibly conflicting, points of view.
■ Understand how information or examples are being used (for example, to provide support for a claim), and how pieces of information are connected (for example, in a narrative explanation, a compare-and-contrast relationship, or a cause- effect chain).
■ Understand, though perhaps not consistently, ways that speakers use language for purposes other than to give information (for example, to emphasize a point, express agreement or disagreement, express opinions, or convey intentions indirectly), especially when the purpose is supported by intonation.
■ Synthesize information from adjacent parts of a lecture or conversation, and make appropriate inferences on the basis of that information, but may have difficulty synthesizing information from separate parts of a lecture or conversation.
Test takers who score at the Advanced level typically can
■ Understand main ideas and explicitly stated important details, even if not reinforced.
■ Distinguish important ideas from less important points.
■ Keep track of conceptually complex, sometimes conflicting, information over extended portions of a lecture.
■ Understand how information or examples are being used (for example, to provide evidence for or against a claim, to make comparisons or draw contrasts, or to express an opinion or a value judgment) and how pieces of information are connected (for example, in a cause-effect relationship).
■ Understand different ways that speakers use language for purposes other than to give information (for example, to express an emotion, to emphasize a point, to convey agreement or disagreement, or to communicate an intention).
■ Synthesize information, even when it is not presented in sequence, and make appropriate inferences on the basis of that information.
那这里就有一个问题了，官方的分类貌似没有分出来我们成绩单分数的22/25/28 + 之间的区别。
总的来说 22-25 还是存在能力上提高的需求的。
