Sir William Osler has a few words for you: “In the Life of a young man the most essential thing for happiness is the gift of friendship.” Truer words were never spoken. For what more could you ask than comradeship during the peaks and valleys of life? To whom else but a close, valuable friend can you show off your successes and complain about your failures or losses?
What is a “good friend”? How is he best described? Well, it has been my observation that although many will cry with you, few can sincerely rejoice (欣喜) with you. Therefore, in my opinion, a good friend is one who can enjoy your successes without envy; one who can say, “That was wonderful! You can do it again, even better if you want!” and mean it. Nothing taxes a friendship more than the prosperity of one and not the other. Even the closest of friendships often cannot resist such pressure and fail. No wonder many minor friendships go down day by day for the same reason.
A person of good character and sound moral, of honor and humor, of courage and belief is a friend to be sought and treasured — for there are few. Too often we hear, “If you can count your good friends on more than one hand, consider yourself blessed.”
What makes a friendship last? Well, I don’t know all the answers, but one of my observations is that most good friends usually have similar tastes. They generally like and dislike many of the same things. There also usually seems to exist a similarity of personality types — especially in the fundamental values of life such as honesty, sincerity, loyalty, and dependability. More often than not, birds of a feather do fly together. I don’t think it matters a lot whether one prefers jazz or hockey to another’s Mozart or ballet. Much other matters far more: relying, sharing, giving, getting, enjoying; a sympathetic ear always there; criticism when it can help; praise — even if only because it would help. With not many people on this earth will you find this much in common. When you find one, hang on to him, for a good friend found is a rare treasure.

There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century．
In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India．In order to reduce fraud（诈骗）, he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay．This finding inspired him to begin investigating fingerprints．In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system．Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist (优生学家). Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system—the first existence．
Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system．In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, they matched Rojas' exactly．She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy（指纹鉴定法）. It's still used in many Spanish-speaking countries．
Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world．

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).
But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.
The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.
Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.
