49.I was under the impression that the tickets were sold out a long time ago.
四級詞匯講解:
be under the impression that…意為“認為,覺得”,該種表達不常見,因此是本句的難點。其實它相當于think或者have the feeling that……。如:
※ I was under the impression that he was kind.我的印象中他挺善良的。
※ I'm under the impression that language is complex.我覺得語言挺復雜的。
※ I am under the impression that it will rain in the afternoon.我覺得下午會下雨。
