2.1 段落层面总技能
边看边秒懂每个句子，明白段落的主要意思，以及段落之间的逻辑关系。
2.2 技能D1：一气呵成看段落
首先能速读、秒懂段落中的每个句子，看完后还要明白段落描述的重点内容是什么。阅读过程需要“一气呵成”，一开始读得不流畅没关系，逐渐改进，慢慢找感觉，找到阅读中文小说那种“行云流水”的感觉。

AbstractDataSource is an abstract base class for Spring’s

implementation.

段落看完后，领会到它重点讲述了：AbstractDataSource是关于DataSource各种实现的基类，自己写DataSource实现要继承它。

D1
一气呵成阅读以下段落，领会主要含义。
1）
Increasing the replication factor of an existing partition is easy. Just specify the extra replicas in the custom reassignment json file and use it with the --execute option to increase the replication factor of the specified partitions.
2）
This form of JPA deployment is the simplest and the most limited. You cannot refer to an existing JDBC DataSource bean definition, and no support for global transactions exists. Furthermore, weaving (byte-code transformation) of persistent classes is provider-specific, often requiring a specific JVM agent to be specified on startup. This option is sufficient only for stand-alone applications and test environments, for which the JPA specification is designed.
2.3 技能D2：一气呵成看多个段落
看多个段落与看一个段落，在难度上总体没差别，只是花费的时间更多而已。阅读时，留意起“承上启下”作用的连词或用于衔接的短语。位置居后的段落，通常与前面的段落构成递进关系，进一步深入说明主题，或者构成并列关系，从其他方面进行叙述。

流畅阅读所有段落，开始看第二个段落时，留意连词。
Through Blue Ocean
If you are new to Jenkins Pipeline, the Blue Ocean UI helps you set up your Pipeline project, and automatically creates and writes your Pipeline (i.e. the Jenkinsfile) for you through the graphical Pipeline editor.
As part of setting up your Pipeline project in Blue Ocean, Jenkins configures a secure and appropriately authenticated connection to your project’s source control repository. Therefore, any changes you make to the Jenkinsfile via Blue Ocean’s Pipeline editor are automatically saved and committed to source control.
...
这个小标题省略了几个单词，完整的是：Set up your Pipeline project through Blue Ocean. 标题即揭示主题：通过Blue Ocean创建Pipeline项目，其下两个段落都围绕这一主题展开。
第二段开头的As具有衔接上下文的作用，让行文紧凑。两个段落之间总体上构成并列关系。

一气呵成阅读以下段落，把握段落之间的关联。
Balancing leadership
Whenever a broker stops or crashes, leadership for that broker's partitions transfers to other replicas. When the broker is restarted it will only be a follower for all its partitions, meaning it will not be used for client reads and writes.
To avoid this imbalance, Kafka has a notion of preferred replicas. If the list of replicas for a partition is 1,5,9 then node 1 is preferred as the leader to either node 5 or 9 because it is earlier in the replica list. By default the Kafka cluster will try to restore leadership to the preferred replicas. This behaviour is configured with
