3. there be 句型中的动词 be 有时可根据情况换成其他动词(如live, remain, seem, appear, exist, happen, stand, lie, come 等) 。如:

注:在这类句型中,有时将地点状语提前(置于句首),则可以省略 there 。如:

4. 在“there be+名词+动词”句型中,其是的动词根据情况可用现在分词(表示在进行或持续)、过去分词(表示被动关系)、不定式(表示动词未发生)等 。如:
There is a magazine lying on the ground. 地上有本杂志 。
There is much work to do [to be done]. 有许多工作要做 。
There were ten people killed in the accident. 事故中有10人丧生 。

People don’t want there to be another war. 人们不希望再打战 。
There being nothing else to do, we went home. 由于没什么其他的事要干,所以我们就回家了 。
注:用作介词宾语通常要用 there being, 但若用作介词 for的宾语则是个例外(即要用 there to be) 。比较:
They asked for there to be another meeting. 他们要求再开一个会 。
We planned on there being another meeting. 我们计划再开一个会 。

有个别现在分词用于该结构时可以表示将来(正如它们可用进行时表示将来一样):

2. there be+宾语+过去分词 。过去分词表示一种被动关系,同时表示动作已经发生:

有时过去分词也可表示一种状态(可转换成被动结构):
There were some old men seated (=who were seated) in the back. 有些老人坐在后面 。
There is a red car parked (=which is parked) outside the house. 房子外边停着一辆红色汽车 。
3. there be+宾语+不定式 。不定式通常表示动作尚未发生:

There was a large crowd to send him off. 有一大群人要来给他送行 。
There was so much to lose that we couldn’t take any risks. 可能会有很大的损失,因此我们不能冒险 。
【注】当其中的宾语与其后的不定式为被动关系时,可用主动表被动,也可用被动式:

有时其中的不定式为系表结构:
