全程说英文用英语怎么说

"Throughout" 或 "throughout the whole process" 可以用来表示"全程"。
"Throughout" 是一个副词，来源于中世英语中 "thoru" 和 "out" 的组合，意思是"通过整个过程"。
例句:
Throughout the game, the home team played with great energy.
(在整个比赛中, 主队非常积极地参与)
The company will provide training throughout the onboarding process.
(公司将在整个上岗过程中提供培训)
The company has been working on this project throughout the year.
(公司在整个一年中都在致力于这个项目)
另外，"throughout the whole process" 也是一种说法，意思同上。
例句:
They were in constant communication throughout the whole process.
(在整个过程中，他们保持着不断的沟通)
I have been studying English throughout the whole process.
(我在整个过程中一直在学习英语)
