参考答案C

解析: There are two kinds of memory: short term and long term.Information in long term memory can be recalled at a later time when it is needed.The information may be kept for days and weeks.(23) In contrast,information in short term memory is kept for only a few seconds, usually by repeating the information over and over. The following experiment shows how short term memory has been studied. Henning studied how students Who are learning English as a second language remember vocabnlary. The subjects in his experiment were 75 college students.They represented all levels of ability in English: beginning, intermediate, advanced,and native speaking students.To begin with, the subjects listened to a recording of a native speaker reading a paragraph in English.Following the recording, the subjects took a 15 question test to see which words they remembered.Each question had four choices.The subjects had to circle the word they had heard in the recording. Some of the questious had four choices that sounded alike.For example, weather, whether,wither, and wether are four words sound alike.Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning.(24) Finally the subjects took a language proficiency test. Hennlng found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning.(25) Hennlng's results suggest that beginning students hold the sound of words in their short term memory, and the advanced students hold the meaning of words in their short term memory.
How is the information in short term memory kept?
C.【精解】文中提到，短期记忆的信息可能只会保存几秒钟，通常需要不断地重复。故答案为C.
