Look at the poster! There a speech about Canadian culture in our school next Saturday.

A. has

B. will have

C. will be

D. is going to have

答案：

A. has

B. will have

(答案→)C. will be

D. is going to have

解析：There be句型表示“某地(或某时)存在有某人(或某物)，而并非某地(某人、某物或某时)拥有什么东西”，句中有若干个名词作主语，动词be常与后面主语中的第一个名词在数上一致。have一般表示某人有某物。句意：看这个海报！我们学校下周六有一场关于加拿大文化的演讲。结合语境可知选C。
