Today I'll help you understand English prepositions Short as they are, prepositions are many people's nightmares because they have different usages and meanings when collocating with different words Such flirty players Then what should we do? How to learn prepositions? First of all, let's get clear on the definition of prepositions Prepositions describe relationships After a preposition we'll put a noun, namely the object of the preposition The whole unit is called a prepositional phrase such as on the floor, in the room, beside the chair on, in, beside are prepositions the floor, the room, and the chair are the objects of the prepositions If we put these prepositional phrases in a sentence they'll have different functions according to different positions If it's after a noun, it's used as an adjective to modify the noun the puppy on the floor If it's after a be verb, it's used as a complement to modify the noun The puppy is on the floor If it's after a verb, it's used as an adverb to modify the verb The puppy sat on the floor Wherever the prepositional phrase is it always describes the relationship of the words it modifies the puppy on the floor, the puppy is on the floor, the puppy sat on the floor Besides nouns, things that can "be used as nouns" like pronouns, gerunds and noun clauses, can be put after a preposition and be used as the object of the preposition to form a prepositional phrase such as "against me" a preposition and a pronoun, me "without stopping" a preposition and a gerund, stopping "for what he has done" a preposition and a noun clause, what he has done There are many common prepositions including at, on, in, from ... by...with... ........ to…...(Go on, not over yet, not over yet) ........... from.....? (You already said it!) Hahaha really? at, on, in, from, to, for, of, with, by, etc. Prepositions have many different meanings when collocating with different words Today's video is mainly the basic introduction to prepositions so we won't explain in detail what different meanings there are under different circumstances As for more detailed lessons, in the future ..... Will we do it? (May...Maybe?) Today we're gonna talk about top 3 commonly seen prepositions: at, on, in and how they describe positions and time These 3 are usually used to describe different kinds of places and time Although you can memorize their collocations one by one if you get the hang of prepositions, you can still infer some usages Technically, at, on, in respectively indicates points, surfaces, and spaces Now let's see how to use at, on, in to describe positions and time When these 3 are used to describe positions, "at" is for a point, "on" for a surface, and "in" for a space "At somewhere" indicates an exact point such as at the table, at the bus stop, at the store "On somewhere" indicates a surface such as on the second floor or on the street "In somewhere" indicates a space It can be big as a universe or small as a cup such as in the world, in the river, in the room But some places can be modified by different prepositions In such cases the meanings are a little different For example Beach 海灘, at or on? If it's "at the beach," it means the exact location, the beach If it's "on the beach," it means the surface of the beach Office 辦公室, at or in? If it's "at the office," it means the exact location, the office If it's "in the office," it means inside the office Water 水, on or in? If it's "on the water," it means upon the surface of the water If it's "in the water," it means inside the water You still with me? All right? Is it too boring for you? The following are simpler anyway When we use these 3 prepositions to describe time "At" indicates precise points in time "On" indicates certain days or dates "In" indicates long periods "At a certain time" emphasizes the moment when something happens such as at noon, at 6 o'clock "On a certain time" indicates specific dates such as on Friday, on April 1st, on Halloween "In a certain time" describes a longer period of time such as in the morning, in September, in spring, in 2015 Is that simpler? Here we have an interesting point in time, weekend Some say "at the weekend," "on the weekend," while others say "in the weekend" When you're not sure which preposition to use I recommend you go to Google Ngram and check how most people use it In Google Ngram, you can use commas to separate the collocations you want to compare The search engine will tell you which usage is more common Here we can tell "on the weekend" is the most common one Alright!
