One day in 1848 a carpenter called Marshall, who worked in a saw mill on the American River in California, made a remarkable discovery. He noticed some bright yellow particles in the water, bent down to pick them up and took them to his partner, Mr. Sutter. This was the beginning of the Californian Gold Rush. Sutter was a Swiss who had come to America some years earlier to make his fortune. The Governor of California had given him permission to found a settlement in the Sacramento Valley and his determination and energy had made him rich. He had built the mill in partnership with Marshall in order to make use of the abundant natural fresources of his land.

Sutter realized the importance of the discovery and decided to file a claim so that his right to the gold would be established. So he sent a man named Bennet to San Francisco to see the Governor. He warned Bennet not to tell anyone in case people came to the valley before his claim was recognised. Bennet could not keep secret but the people of San Francisco did not believe him at first. Then the editor of a weekly newspaper there, Sam Brannan, went to Sutter’s mill to make a report. When he came back he ran through the streets of the town shouting ‘Gold! Gold!’Within a month almost the entire population, then only 800 people, had gone to look for the precious metal. Soldiers deserted the army, sailors left their ships and men gave up their jobs so as not to miss the chance of becoming rich.

The news spread across America to Europe and thousands of people joined in the search. Those who went by ship had to sail round Cape Horn to reach California but some chose the overland route across America and wagon trains were formed for travellers to make the journey. Even then there were some who were prepared to cross the terrible desert of Death Valley in order to reach the gold a few days before the rest

The Gold Rush proved a disaster for Sutter himself. For years he tried to evict the prospectors from his property so that his family might enjoy the wealth of his land, but his busmess was ruined. The prospectors did a great deal of damage, and killed one of his sons, and at the end of his life he was a poor man who continually stopped people in the street to tell them that Gold is the Devil.

Bạn có thể tham khảo bài của mình.

a ) Nếu người con trai bị tai nạn giao thông mất nhiều máu và cần truyền máu gấp thì cả người bố và mẹ đều có thể truyền được vì 1 trong 2 nhóm máu này khi truyền vào nếu là nhóm máu A thì beta sẽ kết hợp với A trong nhóm AB. Còn nếu là nhóm B thì anpha sẽ kết hợp với B trong nhóm AB.

b ) Người con trai k thể truyền lại được vì nếu nhóm máu AB có A mà gặp anpha sẽ kết dính ( nhóm máu A ) , B gặp beta sẽ kết dính ( nhóm máu B ) gây tắc mạch máu .
