4．favorite　考查词性转换。此处应用形容词修饰名词author，指最喜欢的作家，故用favorite。

　　5．When/After　考查状语从句的连接词。此处指当/在你走进书店时/之后，故填When/After。

　　6．What　考查感叹句的引导词。"What＋a/an＋形容词＋单数名词＋主语＋谓语"为固定句型，在表意清楚的情况下，主语和谓语常常被省略，故此处用What。

　　7．But　考查连词。根据上下文语境可知，此处表示转折，故用But。

　　8．a　考查冠词。此处指"一个咖啡店"，表泛指，故用不定冠词a。

　　9．sickness　考查词性转换。由上文中的"the author is sick"可知此处表示作者生病了，再由空前的"author's"可知此处应用名词。

　　10．were　考查虚拟语气。此处表示要是你喜欢的作者现在没有生病，你可能就没有机会和老朋友喝咖啡了。表示与现在事实相反的假设，所以应用were。
