First man to live with lions

First man to live with lions

I my personal opinion I believed the first man who tooked the decision of living all interested in wild cats the name George Adamson rings a bell. He was called “Father of lions”. Adamson lived with them for decades in Kenya. He managed to tread lions as equals.

It has been several years since his death on 20^th August 1989. He got shot by some bandits at Kora Reserve. The first time he decided to raise a cup was after the shot the lioness.

After the retired he dedicated completely to his lions and moved to Kora National Reserved. Once he was there he continued the rehabilitation of lions or orphaned lions to return them into the wild once they were ready.

The most interesting thing of this man is his ability to teach them how to live in the wild and the incredible response from these amazing creatures to his presence.

Modal Verbs of Probability

Modal verbs are used  when we want to make a guess about someting. We choose the verb depending on how sure we are.

• Use 'must' plus the verb when you are 100% (or almost 100%) sure that something is the case.
• Use 'might' or 'may' to express an opinion that you think has a good possibility of being true.
• Use 'could' to express a possibilty which is one of many. This form is not as strong as 'might' or 'may'. It is just one of a number of possibilities.
• Use 'can't' to express an opinion that you are 100% sure is NOT true.

In the present: Subject Modal Base Form Objects I You He, She We They must be might be could be can't be at work.

In the past: Subject Modal Perfect Form Objects I You He, She We They must have left might have left could have left can't have left early.

What is an Infinitive?

The infinitive describes an action, but unlike a regular verb, it is not limited in any way.

An infinitive is the basic form of the verb + "to".

Examples: to buy, to fish, to run, to watch, to tell, and so forth.

• I want to eat.
• They asked us to run.
• "To be, or not to be – that is the question."

Infinitives are often used when actions are unreal, general, or future.


Examples:

• Luis agreed to leave.
• I hope to see you soon.
• She promised to stop smoking.

What is a Gerund?

A gerund is a noun made from a verb. To make a gerund, you add "-ing" to the verb.


Example:

• "I swim every day", the word "swim" is a verb.

• In the sentence "I like swimming", the word "swimming" is a noun.

Therefore, "swimming" is a gerund.


Second example:

•  "She reads several books a week", the word "read" is a verb.

•  "Reading is important", the word "reading" is a noun.

Therefore, "reading" is a gerund.

More examples of gerunds: buying, fishing, running, watching, telling, and so forth.


Examples:

• She stopped smoking.
• I finished doing my homework.
• They keep on fighting.
