【考點lo】decide 的用法
▲ 構詞：decision n. 決定；決心
▲ 搭配：
① make a / one's decision 決定下來，下決心，作出決定
② come to / arrive at / reach a decision 作出決定
③ with decision 斷然
▲ 句型：
① decide to do sth 決定干某事
② decide wh- to do sth 決定何時/如何/在哪里/是否/
干什么
③ decide on + sth / wh- to do sth / wh- clause
④ decide 后跟賓語從句，其含義是“斷定”。
⑤ it has been decided that clause... …已決定
⑥ make decisions / a decision to do sth 決定干某事
▲ 辨析：decide; determine; make up one's mind
該組詞均表達“決定，決心”之意，但decide意為“決定，
決心”，指經過考慮，對疑難問題、爭端等做出決定，含
有取舍之意。determine意為“決定，決心，確定”，指經

強。make up one's mind意為“決定.決心，認定”，多指
拿定主意去做某事，含有不再更改之意，后接不定式或

have you determined where to go for your holiday?你
決定去哪兒度假了嗎?
they have made up their minds to complete the task
ahead of time. 他們已決定提前完成任務。
