这是MHT上placeholder it 的说法 列举了三个情况
我想问的是 比如强调句在内的一些没有列举到的情况 GMAT是怎么看的 (比如这个句子
It is +一段时间+ since从句 It is two years since I became apostgraduate student)
Placeholder It_____________________________
Sometimes it would be nice to move an awkward subject or object to the back of the sentence. In these
cases, we can put an it in the sentence where the subject or object used to be. We call this use of it
“Placeholder It.” Do not look for a noun antecedent for a Placeholder It.
Here are the three situations in which you might want to use Placeholder It on the GMAT.
1. Postpone Infinitive Subjects
Awkward: TO RESIST temptation is futile.
The subject of the sentence is the infinitive phrase to resist temptation. Although this sentence is grammatically
correct, the GMAT usually avoids similar sentences on stylistic grounds.
Better: H is futile TO RESIST temptation.
It is now the grammatical subject. As a pronoun, it refers to the infinitive phrase to resist temptation.
Under other circumstances, it cannot normally refer to an infinitive.
2. Postpone T/wf-Clause Subjects
Awkward: THAT we scored at all gave us encouragement.
The subject of the sentence is a That-Chnse, namely That we scored at all. Again, this sentence is grammatically
correct, since That-CXzxxses containing full subjects and verbs can function as nouns. However,
the position is awkward. Try to postpone a That-Clanst in subject position with an Placeholder It.
Better: H gave us encouragement THAT we scored at all.
Remember, however, that the “Awkward” form could be the right answer!
It cannot normally refer to a clause under other circumstances.

3. Postpone Infinitive or 7/mKlause Objects
Right: She made H possible for us TO ATTEND the movie.
You cannot say this sentence any other way, unless you change the infinitive phrase to attend into the
action noun attendance. Then you should drop the Placeholder It:
Right: She made possible our attendance at the movie.
Right: She made our attendance at the movie possible.
Again, the point of this discussion is that these uses of Placeholder it are legal and even encouraged. If
you come across Placeholder it, do not be anxious because you cannot find a noun antecedent for the it.
There is no such noun antecedent for this use of it.
