Sentences starting with "To conclude," and "To sum up," are commonly seen in English, but can we also use any other verbs like "start" the same way?
I just came across a sentence from a book and it reads:
To start, the application of a gasket to a joint is a requirement if there is a possibility of leakage (vacuum, gas, liquid, or slurry) from the attachment either flowing inwards or outwards. Despite all the best of intentions, there is no such thing as a 100% leak-proof seal.
Here's a another one I saw:
In the first 5 months of 2016, the total new car sales in Mexico reached 587,320 units, up 16.8% from the same corresponding period. The total car production in the first 5 months of 2016 reached 1,354,848 units, down 4.6% from the same corresponding period. In the first 5 months of 2016, the total export reached 1,080,358 units, down 7.1% from the same corresponding period. To review by region, 820,460 units were exported to the U.S. (+0.3% from the same corresponding period; representing 75.9% of the total export volume). 70,862 units were exported to Latin American countries (-30.4% from the same corresponding period; representing 6.6% of the total export volume). 11,175 units were exported to Asia (-68.6% from the same corresponding period; representing 1.0% of the total export volume).
Does the clause "To start" and "To review by region" and the way they are used sound natural to you? I just kind of feel this "To + Verb, " structure does not necessarily apply to all verbs because grammatically the clauses before and after that comma mark should share the same subject, as in the following sentence where the verb "start" and "think" share the same subject "I" :
To start with, I think I must explain the aim of this meeting.
Am I thinking this wrong or am I correct?
