完形填空

阅读下面短文,根据要求完成下面各小题。

Things are going great in Cannes(戛纳), France. I have an exciting experience here. I have only been here at the film festival for two days, but I have already seen four films. When the films are not on, I like to go to watch the fashionable people on the beach. Everywhere you look, there are famous film stars and directors. I saw three of my favourite stars hanging out at the festival yesterday. However, I was too nervous to talk to them.

At this year’s Cannes Film Festival, about twenty films are competing for the main prize, the Palme d’Or(金棕榈奖). The films are from all over the world—Europe, Asia, North America, Africa… 

There are also so many different types of films, and lots of them are from countries which are not famous for the film making business. For someone who loves films, this is heaven(天堂)!

If you come to the festival, the following suggestions will be helpful. First, you’ll need to remember to bring your invitation, because you cannot watch any of the films without one. 

Second, you’ll need to bring some nice clothes. During the day everyone walks around in T-shirts and shorts. But in the evening, everyone has to wear formal(正式的) clothes. I am wearing a long dress all the time!
