_______ a certain doubt among the people as to the pratical value of the
project.
A.It has B .They have C. It remains D.There
raimains
答案是D，虽然 remains
作系动词用，为什么不选C。
_________________________________________________
答：
1、假设选C的话，我们看看会怎么样？
It remains a
certain doubt among the people as to the pratical value of the
project.
这 是 有一个 疑惑 在人们中间
关于 这个项目的实际价值
语法分析：it一定是逻辑主语，那么后面一定要出现他所代替的真正的主语，或者是不定式、动名词，或者是从句。
但是上面的句子中，后面没有任何一部分能够做主语，among the people是介词短语， as to the practical
value of the project
是介词短语。因此这句话肯定是错的。
2、那么D 为何正确呢？这是一个there
be句型的变体，或者叫扩展形式：
在There be 句型中, 除be之外, 某些表示存在概念的不及物动词也可以用于这种句型, 这些动词大致是: live, come, stand, lie，remains 等。请看：
Once there lived an old fisherman near the sea.
海边曾经住着一位老渔夫。
There stands a big tall apple tree in front of my house.
我家屋前有一棵高大的苹果树。
Then there came a knock at the door.
那时传来了敲门声。
本题考点：there be句型的扩展形式，附加考点：句子的语法分析.
补充：there be句型的其他重要考点：
一、There be
结构中的主谓一致
1.当动词be后所接的名词是单数可数名词或不可数名词时，be
应该取单数is；当其后所接的名词是复数的可数名词时，be用复数are。
There's a man at the
door.
门口有个人。
There is some apple juice in the bottle.
瓶子里有些苹果汁。
There are some strangers in the street.
大街上有一些陌生人。
2.如果There be 后面是几个并列名词做主语时，动词be的形式和最靠近它的那个名词保持数的一致。
There is an
ashtray and two bottles on the shelf.
架子上有一只烟灰缸和两个瓶子。
There are two bottles and an
ashtray on the shelf.
架子上有两个瓶子和一个烟灰缸。
二、There be
结构的非谓语动词形式
There be 结构的非谓语动词形式是there to be 和there being
两种形式。在句中作主语、宾语和状语。
1. there being 结构起名词的作用，直接位于句首作主语，通常用it
作形式主语，并且用for引导。
There being a bus stop near my house is a great advantage.
我家旁边有个公共汽车站，很是方便。
It is impossible for there to be any more.
不可能再有了。
2. there
be 结构作宾语时，通常用there to be ，常作这样一些词的宾语：expect，like, mean, intend,
want,prefer,hate等。
I expect there to be no argument about
this.
我期望关于这件事不要再争吵了。
I should prefer there to be no discussion of my private
affairs.
我宁愿不要讨论我的私事。
People don’t want there to be another war.
人们不希望再有战争了。
另外，作介词宾语时，如果是介词for，只能用“there to be”其它介词用“there being”
The
teacher was waiting for there to be complete silence.
老师在等着大家都安静下来。
I never dreamed of there being any good chance for
me.
我做梦也没想到我会有好机会。
3. 作状语的there be 形式，通常用“there being”结构。
There being nothing else to do ,we went
home.
因为没有其他事可做，我们就回家了。
They closed the door ,there being no
customers.
因为没有顾客，他们的店关门了。
三、There be 句型的时态:
There be 句型没有语态形式, 但是却有比较复杂的时态形式, 以及可以表达不同的情态语境,请看下面的例句:
There will be a class meeting this afternoon. (一般将来时)
今天下午有班会。
There was a football match in our school yesterday. (一般过去时)
昨天我们学校有一场足球赛。
There have been great changes in China in the past twenty years. (现在完成时)
