s-v-o
s-v-io

s-v-a

1. S-V-N

2. S-V-O

Explanation:

1. This sentence begins with a subject (S) - global warming. The word that follows, is, is a verb (V) which tells us what the subject is doing or what it represents. The rest of the sentence behind the verb is a noun phrase (a real threat to the planet). When we're talking about sentence patterns, this noun phrase is known as noun predicate (N) because it is a noun that follows a linking verb.

Therefore, S-V-N.

2. This sentence begins with a subject (S) as well - hybrids. Then we have the verb (V) produce which lets us know what hybrids are doing. Then what follows is a direct object - the entire phrase than conventional cars is a direct object (O) because it is what the subject is performing an action upon.

Therefore, S-V-O.
