2022-07-12写总结时，应尽量使用同一种时态

21. In summaries, keep to one tense

1. In summarizing the action of a drama, use the present tense. In summarizing a poem,story, or novel, also use the present, though you may use the past if it seems more natural to do so. If the summary is in the present tense, antecedent action should be expressed bythe perfect; if in the past, by the past perfect. （在总结部分用统一的时态。如果用现在时，过去的行为需要用完成时；如果是过去时，就用过去完成时）

2. But whichever tense is used in the summary, a past tense in indirect discourse or in indirect question remains unchanged. （总结部分不论用什么时态，如果是过去的对话或问题，则应用过去时）

e.g. The Friar confesses that it was he who married them.

3. Apart from the exceptions noted, the writer should use the same tense throughout. Shifting from one tense to another gives the appearance of uncertainty and irresolution.（除了上一条提到的例外，总结部分应当保持统一的时态。切换时态会导致不确定和犹豫不决）

4. In presenting the statements or the thought of someone else, as in summarizing an essay or reporting a speech, do not overwork such expressions as "he said," "she stated," "the speaker added," "the speaker then went on to say," "the author also thinks." Indicate clearly at the outset, once for all, that what follows is summary, and then waste no words in repeating the notification.（总结部分避免过度使用 "he said," "she stated," "the speaker added," "the speaker then went on to say," "the author also thinks."的表达，只需要在最开始的地方使用一次即可）
