1．（2021·全国高一期末）________ seems as if everybody else knew about the truth except me. （用适当的词填空）
【答案】It
【详解】
考查固定句式。句意：似乎除了我，其他人都知道真相。固定句式It seems as if，意为“似乎……；看起来……”，as if后的从句要用一般过去时的虚拟语气，表示和现在事实相反。故填It。
2．（2021·全国高一课时练习）If you want to succeed, it is no use ________ (talk) too much without actually doing anything at all. (所给词的适当形式填空)
【答案】talking
【详解】
考查动名词。句意：如果你想成功，只说不做是没用的。 it is no use doing sth.“做某事是没用的”，是固定句型，故填talking。
