Sandy: I’m really excited about seeing the famous paintings by Picasso.
Wu Lan: Me, too! I'm glad Mr. Smith chose the art museum for our school trip
this year.
Sandy: I’m going to bring my new camera to take lots of photos!
Wu Lan: Oh, no. Mr. Smith says we must not take photos. It’s not allowed in the
museum.
Sandy: That’s too bad! Do you think we may be allowed to take photos if we don’t use
a flash
Wu Lan: Hmm ... I think they just want to protect the paintings. So if you don’t use a
flash, then it may be OK.
Sandy: Yeah. I think we should be allowed to do that. I’ll bring my camera anyway.

Language points
1.I don’t think sixteen-year-olds should be allowed to drive.
→ I think sixteen-year-olds should not be allowed to drive.
否定前移
宾语从句中，若主句谓语动词是
think, believe, suppose, expect, guess, fancy, feel, imagine
等表示心理活动的动词时，宾语从句不能用否定形式；
若宾语从句是否定句式，则常将否定词not前移到主句谓语动词前面，从而形成“形式上否定主句，实际上否定宾语从句”的现象，这种语法现象叫做否定前移。
注意：
这种特殊句型的主语一定是第一人称 I 或者we，若是第二三人称代词（不论单复数）做句子主语，便不能形成否定前移。
