decide 有两个核心用法：① 「决定（做某事）」：decide to do（决定做：decide to leave = 决定离开）；decide on sth.（决定/选定：decide on a career = 选定职业方向）；decide against doing（决定不做：decide against applying = 决定不申请）；② 「裁决，裁定（法律/竞赛）」：decide a case（裁决案件）；the match was decided by（比赛由…决定）。名词：decision（决定：make a decision = 做决定；reach a decision = 达成决定）。辨析：decide（决定，选定选项）vs. determine（确定，查明：determine the cause = 确定原因；也指「决心」：determined to succeed = 决心成功）vs. resolve（决心，书面：resolve to do = 下定决心做）。

语感
decide to do（决定做）；decide on sth.（选定/决定）；decide against doing（决定不做）；make a decision（做决定）；a deciding factor（决定性因素）
决定，做出选择（decide to do = 决定做）裁决，裁定（法律/竞赛：decide a case）
高频搭配：decide to do / decide not to do（决定做/不做）；decide on sth.（选定：decide on a plan = 选定计划；decide on which option = 决定选哪个）；decide against doing（决定不做：decided against applying = 决定不申请）；make a decision（做决定：make an informed decision = 做出知情决定）；reach / come to a decision（达成决定）；a decisive / deciding factor（决定性因素）；undecided（未决定的：remain undecided = 仍未决定）；辨析：decide（决定，选择其一）vs. determine（确定/查明：determine the cause = 确定原因；也指主动决心：be determined to = 下定决心）vs. resolve（决心，书面：resolve to improve = 下定决心改善；比 decide 更强调坚定意志）。
陷阱
⚠️decide to do（后接 to 不定式）——× decide doing
The committee decided to postpone the vote until all members had reviewed the supporting documentation.
✗
× decide doing（× 后接动名词）
✓
decide to do（后接 to 不定式，固定：decide to leave = 决定离开；decide to accept = 决定接受）；× decide doing = 非标准英语；× decide on doing = 可接受但偏口语（decided on going = 决定去）；比较：decide on sth.（选定：decided on the blue one = 选定了那个蓝色的）vs. decide to do（决定做某事）
委员会决定推迟投票，直到所有成员审阅了支持文件。（decide to do，× decide doing）
⚠️make a decision（做决定）——× do a decision / × take a decision（注意动词）
✗
After careful consideration, the management team will take a final decision on the merger proposal at the board meeting next week.
经过仔细考虑，管理团队将在下周的董事会会议上就合并提案做出最终决定。（make a decision = 国际标准；take a decision = 英式英语接受）
make a decision（做决定）是美式和国际标准英语；take a decision = 英国英语（British English）可接受，尤其在英国政治/商业文件中（the cabinet took a decision = 内阁做出决定）；× do a decision = 不正确；此句 take a decision 在英式英语中正确，但 make a decision 在全球英语教学中更标准；若用美式/国际标准：make a decision
✓
After careful consideration, the management team will make a final decision on the merger proposal at the board meeting next week.
经过仔细考虑，管理团队将在下周的董事会会议上就合并提案做出最终决定。（make a decision，× do a decision）
