that..的固定句式，意为“的确…，减然”，表示对某种观点持肯定态度，其中that引导主语从句，it是形式主语；which引导非限制性定语从句，修饰先行词learning。2.In a word,there is no denying that lifelong learning is inevitable and essential.本句使用了there is no denying that..的固定句式，意为“毋庸置疑…，无疑…”，用来表达强烈的肯定语气。光3.Only through lifelong learning can we avoid getting left behind.本句采用了部分倒装句式，当oy所修饰的状语置于句首时，句子的谓语部分必须采用部分倒装句式，即be动词、情态动词或助动词需提至主语前面，比如此处的can we。这种句式也是表达强烈语气的一种常见方式。Listening ComprehensionSectionANews Report One【听力原文】Some unusual weather from around the world.Starting in the US state Washington,more than 63 centimetersof snow fell in just
