Yes, he must. / No, he neednt.2)表猜测，如：He must be over forty.二、课文主要语言点My aunt Jennifer is an actress. 1)Jennifer是my aunt的同位语，其补充说明作用。注意aunt存有英美语发音上的差异。 2)actress，女演员。原形为act，表示表演。actor，男演员。She must be at least thirty-five years old. 1)句中的must表猜测，是对she当前的年龄的猜测，所以直接使用了must be的形式。 2)at least，至少。相反的表达为：at most。In spite of this, she often appears on the stage as a young girl. 1)in spite of，即使，是个介词短语，后面不能接句子。 2)appear on the stage，在舞台上表演。 3)as，表示作为、担任。Jennifer will have to take part in a new play soon. 1)will have to，表示她将不得不。 2)take part in，参加。This time, she will be a girl of seventeen. 1)this time后面用逗号隔开，起到强调作用，凸显这次她要扮演的角色。 2)a girl of seventeen，十七岁的女孩。类似的表达有：a boy of seven。In the play, she must appear in a bright red dress and long black stockings. 1)in+衣服，表示穿着.衣服。 2)bright red，鲜红色。Last year in another play, she had to wear short socks and a bright, orange-coloured dress. 1)注意wear(穿着，强调状态)与put on(穿上，强调动作)的区别。 2)orange-coloured，橙色的。也能够直接用orange来表示。If anyone ever asks her how old she is, she always answers, Darling, it must be terrible to be grown up! 1)if anyone ever asks her how old she is，注意句中的how old she is的语序，虽然是问句，但因为用在宾语从句中，所以要用陈述句语序。 2)it must be terrible to be grown up，must表猜测。grown up，成熟的、成人的。三、读写重点注意解读Jennifer最后的一句话“Darling, it must be terrible to be grown up!”，表达出了Jennifer害怕青春逝去的担心
