Holmes said, “Somebody sent a letter with five pips (桔核) in it from India, and arrived seven weeks later to kill John’s uncle. Then they sent five pips from Scotland and arrived three days later to kill John’s father. Now they have sent five pips to John from London!”

“The letters are all from sea ports. The writer was on a ship when he wrote the letters,” I replied.

“Very good, Watson! And John’s enemy is in London already!”

“Well, I hope they won’t kill young John,” I said.

But they did. The next morning, we read in the newspaper that a policeman found him die near Waterloo station. Holmes was very angry about it.

“He came to me for help and those men murdered him! I’m going to find them, if it’s the last thing I do!” he said to me, and he hurried out of the house.

At night, when he came back, he was tired, but pleased, he said, “I know the names of John’s enemies! And now I’m going to send them a surprise! This will frighten them!” He took five pips from an orange and put them in an envelope (信封). On it he wrote “S. H. for J. C.

“I’m sending the pips to captain James Calhoun. His ship is called the Star. He and his men are sailing back to Georgia, USA.”

“How did you find him, Holmes?” I asked.

“Ship’s papers,” he said, “I’ve looked at hundreds of them today. Only one ship, the Star, was in the three ports at the right times, this morning the Star left London to sail back to Georgia. I found out that the captain and two of his men, all Americans, weren’t on the ship last night, so I’m sure they killed John. When they arrive in America, they’ll get the pips and then the police will catch them!”

Are you happy most of the time? Or do you easily get angry sometimes? Everyone has a different temperament(脾气). It is usually believed that both genes(基因) and environment may affect people’s temperaments in different ways. Scientists have found that the season of the birth also plays a role.

Scientists from Budapest, Hungary, studied 400 university students. In the study, the students need to finish a questionnaire(问卷). The purpose of it was to find out which of four kinds of temperaments they most had. From the questionnaire, scientists found that the students always answered something like "My mood often changes for no reason."and "I love to deal with new projects, even if it is risky."These answers were then matched with their birthdays.

They discovered that people born in summer easily change between sad and happy moods compared to people born in winter. Those who always feel positive are mostly born in spring and summer.

The study also found that those born in autumn less probably had a mood of depression which may easily drive them to cry, while those in winter were not easier to be angry.

Scientists said that this was probably because the seasons had an influence on certain chemicals in the human body. And the chemicals are important to control people’s moods even in adult life.

"It seems that when you are born may increase or decrease your chance of developing certain mood disorders(紊乱) ," lead scientist Xenia Gonda told the Telegraph.
