Can you tell me if these are correct? I have to tell if the verb is transitive or intransitive.

1. Charles Dickens described the slums of London in his novels.

2. Terrible slums and poverty existed along the riverbanks.

3. In ancient times, traders from other countries sailed up river.

4. Ancient Romans built the first bridge across the river.

5. The depth of the Thomas River changes with the tides every day.

1.described=transitive
2.existed=intransitive
3.sailed=intransitive
4.built=transitive
5.changes=intransitive

Congratulations! All are correct!

1. Charles Dickens described the slums of London in his novels.

To determine if the verb is transitive or intransitive, you can ask yourself: Is there a direct object receiving the action of the verb? In this case, the verb "described" is transitive because it has a direct object: "the slums of London."

2. Terrible slums and poverty existed along the riverbanks.
To determine if the verb is transitive or intransitive, ask yourself: Is there a direct object receiving the action of the verb? In this case, the verb "existed" is intransitive because it does not have a direct object. It describes a state of being.

3. In ancient times, traders from other countries sailed up river.
To determine if the verb is transitive or intransitive, ask yourself: Is there a direct object receiving the action of the verb? In this case, the verb "sailed" is intransitive because it does not have a direct object. It describes the action of sailing without specifying what is being sailed.

4. Ancient Romans built the first bridge across the river.
To determine if the verb is transitive or intransitive, ask yourself: Is there a direct object receiving the action of the verb? In this case, the verb "built" is transitive because it has a direct object: "the first bridge across the river."

5. The depth of the Thomas River changes with the tides every day.
To determine if the verb is transitive or intransitive, ask yourself: Is there a direct object receiving the action of the verb? In this case, the verb "changes" is intransitive because it does not have a direct object. It describes the action of changing without specifying what is being changed.

So, your answers are mostly correct:
1. Transitive
2. Intransitive
3. Intransitive
4. Transitive
5. Intransitive
