1 There is going to be a class meeting this afternon.
因为be going to后面跟动词原形.am is are的原形是be,所以填be.
2 There will be a talk about America country music in our school tonight.
因为表示“客观存在,即有,”的时候,我们用句型there be,.
3 There are a few sheep in the field.
因为在修饰可数名词复数形式的时候,应该用a few.much和little都是修饰不可数名词的,不可以用.
4 There will be an important meeting tomorrow.
理由同第二题.
5 There are rows of white houses by the river.
rows of表示几排,.
