Scientists are fond of running the evolutionary clock backward, using DNA analysis and the fossil record to figure out when our ancestors stood straight and split off from the rest of the primate evolutionary tree. But the clock is running forward as well. So where are humans headed? Here's a thoughtless assessment of possible paths, ranging from similar humans to alien-looking hybrids bred for interstellar (星际的) travel.
Different populations of a species have to be separated from each other in order for those populations to diverge into separate species. Populations are increasingly in contact with each other， leading to greater gene-mixing. It's believable that separate species would appear. Evolution is still at work and the trend may well be accelerating. Cultural diversity is fading as human society becomes more interconnected globally.
The radical king of evolution moves much more quickly than biological evolution. High-tech improvements are ranging from Supermen, to camera-equipped flying drones（遥控飞机）, to pills that keep soldiers going without sleep or food for days. To date, genetic medicine has focused on therapies that work on only one person at a time. The effects of those therapies aren't carried on to future generations. Tinkering with the germline could conceivably produce a superhuman species in a single generation-but could also conceivably create a race of monsters.
Today the rapid pace of cybernetic(计算机控制论的) change has led to worry that artificial intelligence may outpace human’s natural smarts. In some fields, artificial intelligence has already bested human. We're already making machines that can be assimilated (同化) including artificial limbs, mechanical hearts, and artificial retinas (视网膜).
If humans survive long enough, there's one sure way to grow new branches on our evolutionary family tree by spreading out to other planets. If humans established a permanent settlement on other planets, the radically different living conditions would change the evolutionary equation (方程式) What will be inconceivable millions of years from now?

In recent years advances in medical technology have made it possible for people to live longer than in the past. New medicines and machines are being developed every day to extend life. However, some people, including some doctors, are not in favor of these life extending measures, and they argue that people should have the right to die when they want. They say that the quality of life is as important as life itself and that people should not be forced to go on living when conditions of life have become unbearable. They say thatpeople should be allowed to die with dignity (尊严) and to decide when they want to die. Others argue that life under any conditions is better than death and that the duty of doctors is always to extend life as long as possible. And so the battle goes on and on without a definite answer.

C. The argument hasn’t ended yet.
D. The quality of life is not as important as life itself, so it is generally thought that people should not be allowed to die under any conditions.
"Mark Twain" was the name used by Samuel Langhorne Clemens (1835-1910) when he wrote books. His father was a lawyer, but a poor one, who lived at Florida, Missouri. The family was so poor that Samuel did not receive much teaching. He had to learn all that he could from the people whom he met. His father died when he was very young, and then there was even less money than before.
Many of the men in this part of America worked in the ships on the great River Mississippi, and he did this himself at one time (1857).
Where did he find the name "Mark Twain"? It came from the great river itself. It was part of one of the cries used by men who worked in the ships. When a man called "By the mark twain!" he meant that the river was "two marks deep" there, that is to say, six feet deep ( "Twain" is an old form of the work "Two".) Samuel Clemens often heard these words when he was young, and he used them as a penname all his life.
During his work on the Mississippi he met travelers of all kinds, and this helped him a great deal when he started to write. But the number of travelers became smaller when war started in America in 1861. Many of the great ships on the river stopped work. Samuel left then and went to Nevada with his brother, who was at that time Governor of Nevada. There, near the town of Carson, Samuel became a gold miner, but he never made much money at the time. He soon saw that life in the gold mines was not for him. He also tried writing for the newspapers in Nevada, and this seemed more hopeful. He found that he could write.
He went to Europe in 1867 and visited France and Italy. In 1870 he married Olivia Langdon, and two years later he was spending nearly all his time writing. Among his books is his own story (1908).
He is now always known as Mark Twain, and many people do not even know that his family name was Clemens. He traveled in America and in England, and went to Oxford in 1907. He was one of the great American writers of the time, and could make his readers laugh – a thing which few writers can do. He died in 1910.

To swim across the English Channel takes at least nine hours. It‘s hard work and it makes you short of breath. To fly over the channel takes only twenty minutes as long as you’re not held up at the airport， but it‘s an expensive way to travel. You can travel by hovercraft （气垫船）if you don’t mind the noise and that takes forty minutes. Otherwise， you can go by boat， if you remember your sea-sickness pills. All these means of transport have their problems， and the weary（厌烦的）traveler often dreams of being able to drive to France in his own car. “Not possible， you say. Well， wait a minute. People are once again considering the idea of a channel tunnel or bridge.” This time， the great London Council（议会）is looking into the possibility of building a channel link straight to London. A bridge would cost far more than a tunnel， but you would be able to by rail or by car on a bridge， yet a tunnel would provide a rail link only. Why is this idea being discussed again？ Is Britain realizing the need for links with Europe as a result of joining EEC？ Well， perhaps， the main reason， though， is that a tunnel or bridge would reach the twenty square kilometers of London‘s discussed dockland（船坞）。 A link from London to the continent would stimulate（刺激） trade and revitalize（使重新具有活力）the port， and would make London a main trading center in Europe. With a link over the Channel， you could buy your fish and chips in England and be able to eat them in France while they
are still warm！
