Robinson saved the savage on Friday, so he named the savage "Friday". This name is related to Robinson's consistent emphasis on time. In the original work, there are many records about time. He remembered that he came to the island on September 3th, and after eleven or twelve days on the island, he thought of using a knife to carve marks on the big pillars to record the year, month and day ... So it is reasonable to give the savage time to name.

2. Now I'm going to lead a melancholy and lonely life unheard of in the world.

This sentence is a portrayal of Robinson's island life. The life he wants to live is unheard of, and his mood is melancholy and lonely. Being alone in an isolated island, it can be said that the difficulties Robinson faces are not only the embarrassment of food and shelter, but also loneliness and despair. How to overcome his mental depression and disappointment is the key to his survival on the island.

3. I don't want it to hold anything for me, and I don't want it to be my companion. I just want it to talk to me, but it can't.

There is a dog on the island, which should be said to be a good companion. Robinson said this, which is a manifestation of his extreme loneliness. People need to communicate. After this idea is too strong, I hope the dogs around me can talk. This also reflects Robinson's loneliness and helplessness. It is no wonder that when Robinson met "Friday" later, there was such a description: "But at this moment, the first man who was knocked unconscious woke up, so I pointed to him and showed it to the rescued savage. This man immediately told me a string of words that I didn't understand, and I felt indescribable kindness, because this was the first time I heard a human voice since I came to a desert island for 25 years. "

4. On the whole, it has been proved that my current unfortunate situation is rare in the world. However, even in such a situation, there are some negative things or positive things to be thankful for.

This passage should be understood in combination with Robinson's arrangement of "luck" and "misfortune" living on a desert island: being alone and living on a desert island is a great misfortune and a negative thing. However, compared with his partner who died in the sea, he is still lucky. After all, he is alive and there is hope, so he should be grateful. This sentence is a concentrated expression of Robinson's thought of "content with life".

5. I hope everyone in the world will learn a lesson from my most unfortunate situation, which is that in the most unfortunate situation, we can also compare the advantages and disadvantages, so as to find something to console ourselves.

This sentence is a concentrated expression of Robinson's positive and optimistic attitude towards life. The reason why he can be alone on a desert island for 28 years is closely related to his attitude towards life. He contrasted the advantages and disadvantages, so that he could face the reality rationally and see the spark of hope from despair, thus gaining inner comfort and courage and confidence to persist. This courage and experience of survival is also a good inspiration for people in modern society.
