2 . The computer is a useful machine. It is the most important invention in many years. The oldest kind of computer is the abacus, used in China centuries ago, but the first large, modern computer was built in 1946. A computer then could do maths problems quite fast.
Today computers are used in many ways and can do many kinds of work. In a few years the computer may touch the life of everyone, even people in faraway villages.
In the last few years, there have been great changes in computers. They are getting smaller and smaller, and computing faster and faster. Many scientists agree that computers can now do many things, but they cannot do everything. Who knows what the computers of tomorrow will be like? Will computers bring good things or bad things to people? The scientists of today will have to decide how to use the computers of tomorrow.

3 . When gold was discovered in Coloma, California in 1848, news travelled fast and many went there to find their fortune. Before 1849, California was a place focusing mainly on agriculture. As word of the gold discovery spread, many people left their fields to seek their fortune. With more and more travellers arriving, restaurants and hotels were built to feed and accommodate (提供住宿) them.
On the mining sites, men were often forced to cook for themselves since few gold diggers were women. In the early days, both food and riches were plentiful and miners could uncover $2,000 worth of gold in just one day. When it came to food, there were plenty of wild animals to be hunted, and meat, beans and coffee could be purchased at a reasonable price. Times appeared to be good.
Over time, because the majority of food in California had to be imported, it became very expensive. Simple foods like eggs and bread were sold for one dollar a piece in 1849. Besides, fruit and vegetables were scarce (缺乏的). Therefore, many gold diggers couldn't get enough food, and some even had no food at all at last. But the gold diggers also hated to tear themselves away from their search for gold and turned to quick and simple meals that could be cooked over hot ashes.
During the Gold Rush, San Francisco's famous sourdough (酸面团) bread became a main type of food. Miners would often buy a piece in the morning that would be eaten slowly throughout the day. The Boudin family, who came from France, was partly responsible for putting San Francisco sourdough on the map. The Boudin bakery has used the same sourdough, a piece of socalled mother dough since 1849. And when the 1906 earthquake hit, Louise Boudin managed to save some sourdough, ensuring that each piece of bread that came from the bakery would be linked throughout history. So far the Boudin bakery has remained in California, using the sourdough that is the same as the one in 1849.
