假设你叫王红，于5月7日星期五在学校门口看到两则海报后，决定邀你的好友Harry一起参加其中的一项活动。你赶到Harry住处时，发现他不在。请根据海报内容给Harry 写一张留言条，要他选择其中的一项活动并尽快通知你。

　　Dear Harry,

　　It’s a pity that you are not in, so have to leave you a note. There are two posters at the school gate. One is about the movie “ Gone with the Wind”, which is to be shown at 7 Saturday evening in the school hall. The other is about a lecture on women’s liberation, which is to be given by Prof. Betty Power, writer of the book “ The Other Half of the Sky”, at 7 on Saturday evening in Room 101. I’d like to invite you to either the movie or the lecture, but I wonder which you would prefer. Please let me know your decision as soon as possible.

　　Wang Hong
