Про COME и те его значения, что вы не используете (а могли бы). 1. COME как предлог: • Come May, we’ll finally get rid of that Christmas tree. • Come summer, all the building work should be finished. • Some clouds popping up on radar, widespread showers start to the work week, but drying out come Tuesday. «Когда придёт», а проще говоря – «в». В июне, апреле, в следующем году, летом и т.д. Если вы углядели в этом предлоге сабджанктив – все верно, это он и есть. Вспомните kingdom come (=shalt come). • Come June, it's our 40th anniversary. • A man speaking at a Greensboro City Council said citizens will keep their gun rights come hell or high water (=no matter what). 2. COME = BEGIN: • I've come to tolerate Africans over the years. Some of them. • This stand used to hold paper bags, but gradually came to be used for adult magazines. • How did that phrase come to mean “sorry”? 3. COME DO STH. Поди-ступай-подай-принеси. Должно быть, вы знакомы с аналогичным оборотом через GO. Во фразе GO AND DO STH за ненадобностью отпадает AND: • These "girls" are over 45! Go ask for your money back. • Go be a nigger somewhere else! Такая же тема с COME DO STH: • He can COME WRITE his essay in our room. • Raqqa, Syria: Come take some special photos & vids! • Come give me your hand. Still can be sewn back but next time be careful around circular saws.
