解析：　本题考查动词时态和语态。从语意可知，我没有去听讲座，是因为之前(过去某个时候)没有人通知我，因此应该使用一般过去时态。因为我没有被(别人)通知，故用被动语态，选A项。‎ 答案：　A ‎2．(北京崇文期末)It________that the road will be closed tomorrow for repairs.‎ A．was announced　　　 B．has been announced C．had been announced　　　 D．would be announced 解析：　本题考查动词的时态和语态。题干句子中that到句子结束是宾语从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。‎ 答案：　B ‎3．—We want to sit at the table near the

答案：　B ‎5．—Would you like to go to the cinema with me tomorrow afternoon?‎ ‎—I’d like to，Mum，but I________to a party by Jane.It is her birthday.‎ A．am invited　　　 B．was invited C．will be invited
