知识点扩展

Therewillbe..=Thereis/aregoingtobe.

Therebe就近原则，也就是be动词后面那个名词的单数决定be动词用is，后面的名词是复数用be动词are。

例如：Thereisanappleandsomepearsonthetable.

Therearesomepearsandanappleonthetable.

一般将来时:

是指will+动词原形，或者begoingto+动词原形，表示动作将要发生或者存在的一个状态。

一般有tomorrow，nextmonth,inthefuture这样一些表示将来的时间状语。

paper是不可数名词，需要量词来表达“一张纸”apieceofpaper,asheetofpaper,复数是变量词twopiecesofpaper,twosheetsofpaper.

paper的第二种意思是报纸/论文/试卷。
