Before we start discussing object relative clauses, let's quickly review subject relative clauses so we can see the difference between subject and object relative clauses. So, if you remember from the last video, we had these two sentences "SMC is a community college. It is located close to UCLA." So, we know that the second clause becomes the relative clause, and we know that the subject "it" is replaced with the relative pronoun "that" The subject is the same as the community college. When we take a look at object relative clauses we look at these two sentences "He is the professor. You saw him last week." We're focusing on not the subject "you" instead we're focusing on the object. Ok so, in this sentence "him" is referring to "the professor", so the object in this sentence is the same as this noun in the first sentence so when we put together these sentences, the second sentence will become the relative clause, but we put it together a little bit differently. We have "He is the professor WHOM you saw last week," and we'll take apart each sentence to make it a little bit more clear. Here's another example. "The textbook is heavy. "The students bought it" So, again we have the first independent clause and the second clause will become the relative clause, and in the second clause here, "It" is the object. We have subject "the students" verb "bought" and then the object "it" So when we put them together we have "The textbook which the students bought is heavy." So you can see that this sentence right here fits into this sentence right after the noun it is trying to describe. When we write object relative clauses we use the relative pronouns "who" "whom" "which" and "that". So, we have an additional relative pronoun "whom". We use "who" for people, "whom" for people, "which" for things and also places and as we said "ideas", and that for, everything. So let's take a look at a couple of practice problems. We have "The student is Chinese." "You met her yesterday". So, we have again two sentences, and we want to describe a noun in this first sentence with this second sentence. So we want to describe the noun "the student" with the second sentence Now if you read the second sentence, "You met her yesterday" were focusing on again the object. "The student you met her yesterday is Chinese", so we want to combine these two sentences but we still have the object we need to get rid of it. We need to use a relative clause to connect the second sentence to first sentence, so we come up with "The student whom you met yesterday is Chinese." So, we have all the parts of the original sentence here but we just moved the object right after "the student" and we leave the rest of the sentence. So when we get the complete sentence, we have "The student whom you met yesterday is Chinese." Let's take a look at another example. "We have "The university is located in Arizona." "She attends this University." So if we try to guess which noun we're trying to describe, in the first sentence with the second sentence we look for the noun that's the same in both sentences. So we have "the university" has a subject in the first sentence and in this sentence, "this university" is the object. So, if we combine these sentences we just start by putting this whole sentence in right after the noun we want to describe. which is the university we get "The university she attended this university is located in Arizona." Of course thissentence is incorrect we need to delete "the University" and replace it with a relative pronoun. So, we have "The University which she attended is located in Arizona." So again, you see that we have replaced "this university" since University is a thing we use "which" the relative pronoun "which". We move it to a position right after the noun we're trying to describe, and we get "The University which she attended is located in Arizona. Now you try this practice problem.
