In a verbless clause, the omitted verb will generally be a form of to be (is, are, etc.).Mo2men wrote:Dear Mitch,
I have two questions about the OA??
1- Why is the verb is singular 'is'? what is the rule followed? can you shed light about the subject of the OA?
The omitted verb form must agree with the implied subject.
In the OA, the implied subject of the verbless as-clause is the rate (singular).
Since the implied subject is singular, the implied verb -- is -- also is singular.
The OA abides by this rule.2-In VERBLESS clause, the subject is usually implied to be the preceding clause. How is this applied in sentence on hand?
Thanks
Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow, as [the rate is] seen in the rings visible in the cross sections of their trunks.
Here, the subject of the main clause is the rate, as follows:
The rate at which trees grow is believed to be among the surest indications on Earth of sunspot cycles.
Thus, the subject of the main clause -- the rate -- is also the implied subject of the verbless as-clause.
