Explanation

Here, the plural or singular form is changed according to the 2nd subject ''friends'' which is in plural form,

so we use are in that sentence.

Neither he nor his friends are reading books نہ وہ اور نہ ہی اس کے دوست کتابیں پڑھ رہے ہیں

**Additional Information**

• In this sentence, "neither...nor" is a correlative conjunction that connects two singular subjects, "he" and "his friends."
• When using "neither...nor," the verb agrees with the closest subject,
• which in this case is "his friends," making the verb plural, hence "are" is used instead of "is."
• So, "Neither he nor his friends are reading books" is grammatically correct.

Explanation

It has been raining since last night.

We normally use 'since' with the present perfect(had been) to describe an action or situation that began in the past and continues in the present

Explanation

'He is poor, yet he is honest'.

Here 'yet' will be used as a conjunction.

Sentence - Though he is poor, he is honest.

Main Clause - He is honest.

Subordinate Clause - Though he is poor.

Explanation

we could use ‘if he were’, if the events are imagery or improbable.

‘If he were’ can be used when expressing an imaginary situation in the present that is definitely not true.  

In the given question, he behaves like a king, which is an imaginary situation 

So we have used ‘if he were’, instead of using ‘if he was’.

Explanation

“should” is used to indicate something which is probable.

Here in this case Probability of failure on not working hard.

The sentence, in this case, will be “Work hard lest you should fail”.
