Our hopes of winning were dashed in the semi final
Our competition run came to an end in the semis
To be knocked out of a competition means that you, or your team, lost by being beaten by another team or individual - depending on the type of competition it is.
If your hopes are dashed it means: Destroy someone's plans, disappoint or disillusion. For example,
"That fall dashed her hopes of a gold medal." This term uses dash in the sense of "destroy," a usage surviving only in this idiom.
If you are winning a series of games in a competition it is described as a 'winning run' or a 'winning streak' and if you are then beaten by a team, 'the run comes to an end.'
To be knocked out of a competitionとは、自分のチームまたは自分がその競技でまけてしまったことを意味します。
dash は、計画や希望を台無しにする、という意味があります。
例："That fall dashed her hopes of a gold medal."
あの失敗が彼女の金メダルへの夢をないものにしてしまった。
大会で連続して勝ち続けていることを、'winning run' または 'winning streak'といい、もし負けてしまったら、'the run comes to an end.'と言うことができます。
beatenは beat（打ち負かす）の過去分詞なので、かんたんですね。
England was beaten by France in the semi-final.
（イングランドは準決勝でフランスに敗れた。
eliminateは「取り除く」という動詞で、be eliminatedはその大会から除かれてしまう、つまり敗退することです。
Our team was eliminated in the semifinal.
（我々のチームは準決勝で敗退した。）
なお、semi-finalとハイフン付はイギリス、semifinalと一語なのはアメリカの用法です。
