Canvas tents have been around since before they started making tents out of nylon, polyester and other synthetic materials. I own two canvas tents myself, both a Kodiak and a Springbar.
From Wikipedia, the free encyclopedia. The conditional perfect is a grammatical construction that combines the conditional mood with perfect aspect. A typical example is the English would have written. The conditional perfect is used to refer to a hypothetical, usually counterfactual, event or circumstance placed in the past, contingent on some other circumstance (again normally counterfactual, and also usually placed in the past).
When we want to predict something conditional about the future (what we think might happen), we can use the present tense in the if clause and will or be going + the base form of the verb in the result clause. If Jeffrey grows any taller, the basketball coach is going to recruit him for the team.
