这一段要好好理解。就是说给定s和a，G满足一个分布，可能方差会很大，所以G的值就会很不稳定。这就效果很差。

possibly there is a lil mistake

She touched the clay and the clay seemed to have a bad meaning which let everyone uncomfortable.

It's the third time that this expression appears. Maria always laughed in this way, which shows that she was a very kind person.

According to the former description, Maria was a good and welcome person. But actually there were no ring or man for Maria, though she was aged and was disappointed at this, why?

There are many verbs in this paragraph. Rather than directly depicting her inner thoughts, the author described a series of her actions to show her upset and helplessness.

We can see that Mrs. Mooney is an able and confidence woman. She liked to control everything.

Mrs. Mooney is a very determined and mature person. This may help us understand others' characteristics and the relationship between Mrs. Mooney and other characters better.

"Foolish" is quite an interesting expression. It shows the narrator's adoration of her.

The narrator formally depicted everything as silent and a little unlively. However, he suddenly told us such a beautiful and graceful girl. He must like her very much.

Old Cotter thought the narrator as a child. The relationship between them seemed not good.

These words seemed to Mr. Neave more like moking than praise.

Poor Mr. Neave! Even his children showed no respect and symathy towards him! They were just indifferent to him and didn't know how much their father had did for them. They might just take their happy life for granted. That made Old Neave feel more upset and hopeless.

I think this is Mr. Neave's inner activity. Though the female family member lived a happy life, he suffered a lot to maintain that. These words show his upset and helplessness, because he was not able to change this.

The metaphor suggests that he was too old to move like a normal person. Also, I can also see his great powerlessness for aging.

There are many adjectives which depict the surroundings. Previously the surroundings had been "dark, silent, beautiful, mournful", which means that Leila was unfamiliar with the new environment and a little nervous. But now it "had opened dazzling bright", which indicates she had adapted to the environment.

Leila was from the country and everything seemed novel and fascinating to her. The vigorous atmosphere and beautiful surroundings gave her a good impression. Different from The Garden Party, in this novel the lower class seemed to get along well with the upper class.

The ending is also kind of tragic and ironic, just like the other short stories. Isabel compromised at last. She had totally become "new Isabel".

This indicates that the relationship between William and others was not close but a little distant. Maybe William was tired and stressed.

William might be indfferent to any other people. All his attention was concentrated upon Isabel.

There are many contrasts in this story. What she looked like was "ancient, withered", and she act "slowly". On the contrary, her dress was luxurious. This succesfully depicts a gambler's charater, who pursued a lot of money and was very addicted to gamble.

The contrast between "snuffy old saints" and "croupiers and crowns" is obvious. Maybe it is to indicate the risk of losing everything in the casino.

In the end, they were perplexed about the future.

She was still whispering, even she was told not to do so. She was very nervous and scared because they feared their father, even he had died.

It seems that the colonel had absolute authority over his children.

The averenge length of this story is shorter than that of The Moonstone and The Garden Party, I think, if we measure them. There are some sentences which only contain simple expressions, such as "silence again". Brief as they are, they create a silent atmosphere well.

I found that there are a few conversations that seem meaningless and trival. But these conversations are not of no use. They successfully show the two characters' upset and anxiety after their father's death.

The upper classes just takes everything for granted. No matter what accident happened, they will still live a extravagant life, while the lower class will still live a poor life.

The cook's kindness was quite a contrast to what Mrs. Sheridan had decribed. Maybe this indicates that they who had a higher status sometimes had a stereotype of the workers.

Laura made a compromise at last. Does this mean her innocence would gradually lose when she grew up?

Laura cared little about others' status. Though workmen had different identity from the "silly boys” who were at the same class as her, she'd rather stay with the workmen.

The author is good at using metaphor to protray beautiful things. He describes that the morning, the surroundings and the house are of great beauty and joy, maybe in order to create a symbol of the upper class. This may help to make preparation for the later conflicts.

It is interesting that the characters' outlook is from different culture, like the green turban from Mideast or India, the silk from the east and the kimono from Japan. The diversity of their outlook is just like the beautiful scene around.

It seemed that they began to live a happy life, as the misfortune brought by the Diamond had gone. This may indicate that the mystery of the Diamond had been solved totally and everything would run normally.

This is an interesting expression. If Mr. Ablewhite had not kept the Diamond, his personal reputation would be ruined. So the fact that he took the Diamond away is very reasonable.

I think the reason why his father refused to lend him money might be that his father knew his actual hypocritical character, and didn't want to help him.

That is to say, there wasn't enough evidence to prove that it was the three indians who murdered Ablewhite.

I think Ezra used a contrast between himself and Rachel's outlook. He described himself as ugly wrinkled face, and then praised Rachel's kindness and beauty. This admiration for Miss Rachel let me feel Rachel was a lot kinder than before.

This kind of amusing behavior usually happens when one feels nervous and trys to do something meaningless but relaxing.

Till now, all of Mr. Cuff's three predictions had realized. He would come back to deal with the Diamond again. This is amazing and makes me admire Mr. Cuff more.

Wow! We can make sense of all of Rosanna's strange behaviors. Before she suicided, she discovered that Franklin, the man she loved, was the actual thief. She also knew Franklin didn't realize that it was himself who stole the Diamond. So she decided to keep the truth, and with the sacrifice of herself. Besides,she asked Lucy not to give the letter to anyone but Franklin, just in order to keep others from knowing the real stoler. She was such a humble person who dedicated her poor life to the man she loved. What a tragedy!

He was still missing Mr. Rachel and cherishing the momory there. I think this is a reason why he continued to seek the stealer.

From this paragraph, we can know that Franklin thought Betteredge's discreption of him was beyond the reality. So some narration from Mr. Betteredge may be not that true.

I really like Mr. Bruff. Because we can find him a just and believable narrator without prejudices and too much subjective thoughts, compared with Miss Clack, who conveyed her personal dislike for Bruff in her part. So I think he is the most objective and reliable one among those who had narrated the story till now.

Till now, we can easily know Mr. Bruff's attitude towards other people. He thought that Mr. Godfrey was not a believable person. Besides, he sympathized with Miss Rachel and he wanted to help her.

A little ironic because Miss Clack was such a pious Christian that she thought religion could cure everything, but others seemed not concerned about her advice.

By searching the word Christian, nearly all of them appear in the first narrative by Miss Clack, and this word appears for a lot of times. We can easily notice that Miss Clack is a Christian and she might use the word Christian to describe good things.

Miss Clack might regard Mr. Franklin as a person who was not so spiritually wealthy. That is quite different from what I thought about him before from Betterage's narration. And Betterage had told the reader not to believe what Miss Clark would say about him. So I think in the first narrative there will be something interesting that is different from what Betterage has said.

Why was she anger? Because of the loss of the Diamond which brought bad luck to their life? Or there was some other reasons?

This phrase has appeared for 4 times. It shows that Rosanna was greatly shocked and absent-minded when she heard the words by Franklin. The author depicted a lot to show Rosanna's extreme upset which maybe a lot more serious than before. Maybe he was making a pretext to what would happen later.

I feel so surprised here. In the former narration, the author did not mention the relationship between Miss Verinder and Rosanna (By searching Rosanna, we seldom see Miss Verinder's appearance), but here he told us that Miss Verinder believed Rosanna very much. I admire the author's skill of telling detective stories, that he was good at creating surprises and suspenses. This makes the reader more willing to continue to read.

The appearance of Mr. Cuff seemed weird and unusual, which indicates that he was a very capable man and might make a breakthrough in the event.

Haha these paragraphs around makes me laugh because Miss Rachel was so unconscious of the danger that the Diamond might be lost that it seemed bound to be lost later.

Before this sentence, the author uses lots of words to describe the situations in the dinner party which I think are pretty interesting. They're roughly about Mr.Candy and Mr. Franklin, etc. But I don't think these depictions are closely related to what will happen next that they met the Indians. Actually, sometimes I do find some parts kind of fun but unrelated to the main story. This may be the author's unique personal writing style.

These words by Franklin shows his indifferent attitude towards Rosanna, in contrast to Rosanna's unusual actions. This indicates Rosanna's tragic fate that she would not be loved by Franklin at all.

Just by quote this short sentence from ROBINSON CRUSOE, the narrator not only reemphasizes the importance of the book to him, but also briefly and clearly shows us his decision to obey his lady.

These words are quite interesting. It conveys the narrator's preference for the book.

The author uses many words to suggest Herncastle's bad temper, such as absurdly angry, unlucky temper, fiery temper and exasperated. So by using these words, the author may successfully depict a person's characteristic very well.

In the beginning, one of the author's apparent writing styles, which can be noticed at many places, is that he tried to tell the background in a very objective but convincing way. He just chose the first person to give introduction to the background story that is kind of historical and legendary. This way of writing makes me very addicted to the story and I cannot wait to continue reading !！
