According to the passage, which one is wrong?

参考解析：

细节理解题。根据第三段第三、四句“Half an hour later, however, Blackie had not returned. Tom was feeling worried and felt angry at his friend’s little smile.”可知，半小时之后黑子还没回来，汤姆就有点担心了，因此不可能预计一小时内回来，应该是预计很快回来，因此A项是错误的；根据文章第三段最后一句“Tom was feeling worried and felt angry at his friend’s little smile.”可知，汤姆有些着急，并对他朋友脸上露出的一丝笑意感到生气，因此B项是正确的；根据文章最后一段最后两句“Blackie ran over to the window, barking and wagging his tail. Tom looked out of the door and saw a bone outside.”可知，黑子朝窗子跑去，边叫边揺尾巴，汤姆从门往外一看，看见了一根骨头，由此推知，黑子可能饿了，因此C项是正确的；根据文章第一段第二句“Whenever he got the chance, he would ask his dog to please his friends with some tricks.”可知，一有机会他就会让它玩一些把戏来取悦他的朋友，以此来炫耀黑子，因此D项也是正确的。故选A。
