Explanation:

In this exercise, we need to properly use the verbs "be" and "have" to complete the sentences. Let's go through each sentence step by step:

1. Besides the advantages, the television _____ some drawbacks.

In this sentence, the correct verb to use is "has." We use "has" because the subject "the television" is singular, so we need to use the third-person singular form. Therefore, the sentence should be:

"Besides the advantages, the television has some drawbacks."

2. To tell the truth, there _____ many TV programmes that _____ no cultural or artistic value.

In this sentence, we need to fill in the blanks with the verbs "be" and "have." The first blank must be filled with the verb "are," as we are talking about the existence of many TV programs. The second blank must be filled with the verb "have," as we are referring to the lack of cultural or artistic value possessed by these programs. Therefore, the sentence should be:

"To tell the truth, there are many TV programmes that have no cultural or artistic value."

3. There _____ rather many films about gangsters and killers.

In this sentence, we need to use the verb "are" since we are talking about the existence of many films. We use "are" because the subject "there" is followed by an adjective phrase "rather many." Therefore, the sentence should be:

"There are rather many films about gangsters and killers."

4. We ______ so tired of them.

In this sentence, we need to use the verb "are" because we are expressing a state of being, specifically being tired. Therefore, the sentence should be:

"We are so tired of them."

5. Lately, so many advertisement clips ______ appeared on TV screens.

In this sentence, we need to use the verb "have" since we are talking about the existence of many advertisement clips appearing on TV screens. Therefore, the sentence should be:

"Lately, so many advertisement clips have appeared on TV screens."

6. But still, TV remains the main source of information, and we ______ spending a lot of our free time in front of our TV sets.

In this sentence, we need to use the verb "are" because we are expressing a state of being, specifically spending a lot of free time in front of TV sets. Therefore, the sentence should be:

"But still, TV remains the main source of information, and we are spending a lot of our free time in front of our TV sets."

I hope this detailed explanation helps you understand how to properly complete these sentences using the verbs "be" and "have"!
