Can you tell me if I am correct

Five of your answers are correct.

Which ones are wrong?

Can you tell me which answers are wrong?

1. Look up each verb in a good dictionary or dictionary website, such as here, where I looked up "belong" -- http://www.answers.com/belong

The dictionary entry will tell you if the verb is transitive (trans. or just tr.) or intransitive (intrans. or just intr.)

Let us know what you decide.

I think #4 and #7 are wrong. Is that correct?

#7 The verb "serve" can be either transitive or intransitive, depending on the particular sentence. In this case, it's used as an intransitive verb -- there is no direct object for it.

You're right about #4.

4 is wrong. 7 is correct.

The verb, "serve" has no direct object, so it is intransitive.

"their size might surprise you." is this transitive or intransitive

To determine whether a verb is transitive or intransitive, you need to analyze the sentence structure and the presence or absence of a direct object.

1. "Most people think of Bamboo as a tree or bush." - Transitive (think of)
The verb "think of" is transitive in this sentence as it has a direct object ("Bamboo"). It shows an action being done to something.

2. "Bamboo belong to the grass family." - Intransitive (belong)
The verb "belong" is intransitive in this sentence as it does not have a direct object. It shows a state of being or ownership.

3. "More than 500 kinds of bamboo grow in the tropics." - Intransitive (grow)
The verb "grow" is intransitive in this sentence as it does not have a direct object. It shows a natural process of development.

4. "These plants thrive in warm climates." - Intransitive (thrive)
The verb "thrive" is intransitive in this sentence as it does not have a direct object. It shows a state of flourishing or prospering.

5. "People use bamboo in many ways." - Transitive (use)
The verb "use" is transitive in this sentence as it has a direct object ("bamboo"). It shows an action being done to something.

6. "Engineers strengthen concrete with it." - Transitive (strengthen)
The verb "strengthen" is transitive in this sentence as it has a direct object ("concrete"). It shows an action being done to something.

7. "In Japan, the hollow stems serve as water pipes." - Intransitive (serve)
The verb "serve" is intransitive in this sentence as it does not have a direct object. It shows a purpose or function.

Based on this analysis, your answers are mostly correct except for number 3. It should be "intransitive" as "grow" does not have a direct object.
