32、意：他转过头，看见一个意大利青年，从他身边匆匆走过。此处是非限制性定语从句，先行词是an Italian young man，定语从句中缺少主语，应使用关系代词who引导。故填who。3out考查固定短语。句意：当那个法国人突然发现他的手表不见了时，那人已经快看不见了。固定短语：out of sight“看不见，在视野之外”。故填out。4missing考查形容词。句意：当那个法国人突然发现他的手表不见了时，那人已经快看不见了。此处指“手表不见了”，使用形容词missing“找不到的，丢失的”。故填missing。5it考查强调句型。句意：他想一定是那个意大利人偷了他的表。根据句意及句子结构分
33、析可知，此处是强调句型。故填it。6to follow考查非谓语动词。句意：他决定跟着他把表拿回来。固定搭配：decide to do sth.“决定做某事”。故填to follow。7caught考查时态。句意：不久法国人就赶上了意大利人。此处描述的是过去的事情，应使用一般过去时。故填caught。8pointing考查状语从句省略。句意：法国人指着意大利人的表，用拳头吓唬意大利人。while后面是省略的时间状语从句，省略了the Frenchman和be动词was。还原为the Frenchman was pointing.。故填pointing。9greatly考查副词。句意：当他妻子指着桌子上的手表时，他大吃一惊。此处修饰形容词surprised，应使用副词形式。故填greatly。10had robbed考查时态。句意：现在他意识到他误抢了意大利人的手表。rob发生在realized之前，属于“过去的过去”，应使用过去完成时。故填had robbed。
