23. Connection is a powerful tool helping you learn better. Using connection, you need to take information and connect it to images, examples and things you already understan However, as a skill, this takes some time to develop and it often fails when you face very hard material, and it can also be misapplied，particularly if it’s used as a direct replacement for practice. Here are some ways I’ve used it:
While learning Chinese, I would recognize the radicals (部首）of the characters and try to form a mental picture either with those radicals or the character meaning or the pronunciation, or all three. While studying international business law in France, I used the link and peg (挂钩）method to link the date and place of a particular treaty(协约）which was signed to the name of the treaty. While studying accounting, when I couldn’t remember a rule, I’d make a mental image that encapsulated (概述）it. While learning biology, whenever I couldn’t remember a chemical, I made a list of its properties (性能)，turned those properties into images and linked that to the way the name sounds.
When you’re trying to memorize a lot of information that isn’t well connected, focus on quick and loose images that will help you translate the information, even if they don’t represent it well.(10分)
