For many years, Hawaii has been a magic name to people who like to travel. People on both sides of the Pacific Ocean, in Japan and in America, dream of seeing these beautiful islands in the middle of the ocean. Their dreams always include at least one scene of a sunset over the ocean. In the tropical(热带的) lands, the sun drops, like a ball of golden fire, into the sea, and it droops so quickly that you can almost see it move. The sun leaves behind a glow that lights the skies and shines in the quiet water.
People often have a quiet, peaceful time ---perfect for a leisurely(悠闲的) walk along the water. This scene is not too different from the dramatic(令人神往的) beauty that greeted the first strangers to these islands centuries ago. They were Polynesian people who came from Tahiti in canoes not much bigger than small boats.
They found the beautiful white sand beaches and the waving palm trees, but there were no giant hotels like the ones we see nowadays. The first people came to Hawaii nearly two thousand years ago, but skyscraper hotels were only built in the last 25 years. Now jet planes make it possible to fly to for a weekend from Tokyo. Wherever the people come from, they really want to see the original beauty of Hawaii. They want to see the lovely beaches and the mountain called Diamond Head which is almost hidden by the tall hotels.
【小题1】Hawaii is a name _____.

For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
　　After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.
　　Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.
　　Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids-the very kind of molecules found in all living things.

For many years it was common in the United States to associate Chinese Americans with restaurants and places that wash clothes. People did not realize that the Chinese had been driven into these occupations by the prejudice and discrimination that faced them in this country.

The first Chinese to reach the United States came during the California Gold Rush of 1849. Like most of the other people there，they had come to search for gold. In that largely unoccupied land， the men staked a claim (立界标表明所有权) for themselves by placing makers’ in the ground. However，either because the Chinese were so different from the others or because they worked so patiently that they sometimes succeeded in getting a mining claim to make a profit ( where others saw no way to do so) ,they became the target".Of their competi­tors. They were troubled and attacked in many ways. Often they were prevented from working their claims; some places even passed regulations forbidding them to own claims. The Chinese therefore started to seek out other ways of earning a living. Some of them began to wash clothes for the white miners; others set up small restaurants. (There were almost no women in California in those days and the Chinese filled a real need by doing this" women's work". ) Some went to work as farmhands or as fishermen.

In the early 1860's many more Chinese arrived in California. This time railroad companies brought the men in to build the first railroad line from California to the East. They were sorely needed because the work was so hard and dangerous，and it was carried on in such an isolated part of the country that the railroad company could not find other laborers for the job. As in the case of the first Chinese in America， these Chinese were almost all males; and like them，too，they encountered a great deal of prejudice. The hostility grew es­pecially strong after the railroad project was completed，and the Chinese laborers returned to California—thousands of them，all out of work

Many of today's Chinese Americans are the descendants of some of the early miners and railroad workers.
