Sarah Lynn，an educational consultant and teacher，thinks English learners can improve their ability to remember and use new words by testing themselves. She adds that self-testing improves retrieval (数据检索)-the ability to use and remember new words.

If you are like most learners，you may have faced such a situation：You think you understand a topic. Yet when asked to use what you have learned，you are not able to remember the information. Not being able to retrieve new ideas could happen on a test or even in a conversation.

Learning takes effort. It takes effort because the learning process changes the brain，says Sarah Lynn. One way it changes the brain is by creating connections，which are called dendrites (树突).Lynn suggests that dendrite connections are important for retrieval. There are three main ideas about how to grow dendrites and improve retrieval，making connections，using repetition and testing yourself.

Lynn is not the only expert who recommends self-testing. A paper in Journal of Applied Research in Memory and Cognition says one benefit of testing practice is that it improves retrieval. Retrieving information once makes retrieving that information easier in the future. In addition，the paper says，when students test themselves as part of studying，they learn what they do not know. When students know what they do not understand，they can pay attention to overcoming their weaknesses. Lynn recommends that learners test themselves by getting away from what they are studying. Then，they should test themselves by thinking about what they have learned. She recommends that learners make themselves write or speak something. Lynn suggests reading something or watching a video on the topic，then getting rid of the reading or audio material and summarizing it. This will allow learners to test what they know.

The benefits of such practice，Lynn says，are not just about improving your ability to remember information. By testing yourself，you can build confidence in the skills you
