یکی از قواعد گرامری پرکاربرد در زبان انگلیسی، جملات as … as هستند که در مکالمات روزمره انگلیسی هم بسیار استفاده می شوند. جملات as … as برای مقایسه دو موضوع یا حالت استفاده می شوند که در ادامه به طور کامل آموزش شان می دهیم.

معمولا عبارات احتمال و امکان را به با استفاده از as … as بیان می کنیم. مثال:

As much as, as many as
وقتی می خواهیم به کمیت و تعداد اشاره کنیم از as much as برای کلمات غیرقابل شمارش (uncountable) استفاده می کنیم و از as many as برای کلمات قابل شمارش (countable) استفاده می کنیم.
نکته: در این حالت، بین as many و as دوم، اسم قرار می گیرد.
