Answer 2

I think you are asking me to answer in detail the following sentences, using the passive voice and the correct tense of the verbs in parentheses:

- Usually many folk tales (read) to babies before sleeping. - Many forests (put) on fire by tourists last summer. - His clothes (iron) always perfectly. - Much litter (collect) by voluntaries in the national park yesterday. - He (give) never bad marks. - She (betray) by her friend the other day.

Here are my answers:

- Usually many folk tales are read to babies before sleeping. This sentence uses the present simple passive, which is formed by the verb to be in the present tense and the past participle of the main verb. The present simple passive is used to describe general facts, habits, or routines. For example, "English is spoken in many countries." - Many forests were put on fire by tourists last summer. This sentence uses the past simple passive, which is formed by the verb to be in the past tense and the past participle of the main verb. The past simple passive is used to describe actions that happened in a finished time in the past. For example, "The house was built in 1900." - His clothes are ironed always perfectly. This sentence uses the present simple passive, which is formed by the verb to be in the present tense and the past participle of the main verb. The present simple passive is used to describe general facts, habits, or routines. For example, "The windows are cleaned every week." - Much litter was collected by voluntaries in the national park yesterday. This sentence uses the past simple passive, which is formed by the verb to be in the past tense and the past participle of the main verb. The past simple passive is used to describe actions that happened in a finished time in the past. For example, "The cake was eaten by the children." - He has never been given bad marks. This sentence uses the present perfect passive, which is formed by the verb to have in the present tense and the past participle of the verb to be and the main verb. The present perfect passive is used to describe actions that have a connection to the present, such as an experience, a result, or a change. For example, "The car has been repaired." - She was betrayed by her friend the other day. This sentence uses the past simple passive, which is formed by the verb to be in the past tense and the past participle of the main verb. The past simple passive is used to describe actions that happened in a finished time in the past. For example, "The secret was revealed by the spy."
