There be是一个“存在”句型,表明“有”的意思。
必定句的方式为:There be + 名词(奇数或复数)+地址状语或时刻状语。
be动词单复数的确认,看be后边第一个名词,当所接主语为奇数或不可数名词时,be动词方式为is;当所接主语为复数名词时,be动词为are;当be动词后接两个以上主语时,be动词与最接近主语坚持数上的共同。意思为“某地有或人或某物”。如:
There is an eraser and two pens on the desk. 桌子上有一块橡皮和两支钢笔。
There are two pens and an eraser on the desk. 桌上有两支钢笔和一块橡皮。
