17、本文是一篇说明文。喝下午茶是最为典型的英式传统。浓郁的茶香配上精致、美味的各色茶点让品饮下午茶成为了一件很惬意的事情。本文介绍了下午茶的起源、历史、发展、现状及受欢迎程度。1with 考查介词。此处为“with名词过去分词”的复合结构用法，在句中作状语。2that 考查强调句型。分析句子结构可知，此处为强调句型，“the invention of afternoon tea”是被强调部分，故填that。3a 考查冠词。a popular hobby “一个受欢迎的业余爱好”，此处用不定冠词a表示泛指。4comfortably 考查词性转换。空处在句中修饰“喝茶”这一动作，充当状语成分，应该用副

18、词。5was designed 考查动词的时态和语态。该空在定语从句中充当谓语，design与作主语的关系词之间是被动关系，且由“originally”“dates back to the 1840s”可知应用一般过去时的被动语态。6fashionable 考查词性转换。修饰其后的名词短语social occasion，作定语，用形容词。7popularity 考查词性转换。该空充当介词in的宾语，所以用名词。8although/while/though 考查连词。分析句意可知，句子中存在让步的逻辑关系，所以应用连词although，while或though来引导让步状语从句。9to enjo

19、y 考查非谓语动词。此处为动词不定式在句中充当目的状语。10being asked 考查非谓语动词。动词avoid后需接动名词作宾语，并且ask和you之间是逻辑上的动宾关系，故用动名词的被动式being asked。*完形填空。we have all heard of giant pandas, and know that they are endangered. when one has babies, it makes national news _1_， and pictures of their babies are _2_ circulated. but it now seems
