Active Voice And Passive Voice?

Anonymous1.The sugar is blended with the butter until a smooth mixture is obtained.
2.He was not expected to check his iphone every hour, but he was expected to call the office once a day.

We blend the sugar with the butter until we obtain a smooth mixture.

"The office" didn't expect him to check his iphone every hour, but they did expect him to call in once a day.
(casual use of "the office," "they," and "call in.")

Please offer some attempt at answering the questions. Thanks!

Best regards, - A.

AnonymousI have couple of doubts changing active - passive and vice versa,,, here are the sentences,
1.Passive to Active voice.
1.The sugar is blended with the butter until a smooth mixture is obtained.
2.He was not expected to check his iphone every hour, but he was expected to call the office once a day.

You can't convert these 'short passives' to actives without knowing who the obligatory subject of the active version is. So, these active voice versions are clearly ungrammatical:

1. *Blends the sugar with the butter until a smooth mixture is obtained..

2. *Expected him to check his iphone every hour, but expected to call the office...

It's a wrong question. The 1. and 2. are in active voice. So, you have to put the subjects of the 1. & 2. ( 'sugar' and 'he') in the object positions to have sentences in the active voice in order to change them into the subjects of passive sentences:

They blend the sugar with the butter until a smooth mixture is obtained. (active voice)

The sugar is blended with the butter until a smooth mixture is obtained. (passive voice)

His boss didn't expect him to check his iphone every hour, he expected him to call the office once a day. (active voice)

He was not expected to check his iphone every hour, but he was expected to call the office once a day. (passive voice)

Part of the charm of the passive voice is that the actor doesn't need to be named.

Anyone who asks you to make a transformation to active voice should know this,
and expect you to make up (invent) the actor.

How is the question wrong?

You need to rethink the parts in bold, or at least explain in greater detail. You seem to contradict yourself later in your post.

Clearly so.
But where did they come from?

Mix it well until smooth and well combined.
