Lesson 17 Always young 课⽂内容： My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, ‘My dear, it must be terrible to be grown up!' 本⽂语法：情态动词must和have to的⽤法 语法归纳：must通常表⽰主观上的“必须”，have to通常表⽰客观上的“不得不”。
1)has / have to = has / have got to，后者常常⽤于⼝语中。
2)has / have to 的过去式为had to。
例如：You must clean your own room.你必须打扫你的房间了。
I have to leave at 6 o’clock this afternoon.今天下午六点钟我必须得⾛。
Last winter, we had to wear gloves and scarf.去年冬天，我们不得不戴上⼿套和围⼱。
