「英語四級(jí)」聽力口語關(guān)鍵句：49. I was under the impression that

49. I was under the impression that the tickets were sold out a long time ago.

點(diǎn)睛

be under the impression that...意為“認(rèn)為，覺得”，該種表達(dá)不常見，因此是本句的難點(diǎn)。其實(shí)它相當(dāng)于think或者h(yuǎn)ave 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(fù)雜的。
I am under the impression that it will rain in the afternoon. 我覺得下午會(huì)下雨。
