Text B. “The USA Science Centers”
1. Read and translate the text.
Silicon Valley is the southern part of the San Francisco Bay Area in Northern California, United States. The term originally referred to the region's large number of silicon chip innovators and manufacturers, but eventually came to refer to all the high-tech businesses in the area; it is now generally used as a metonym for the high-tech sector. Despite the development of other high-tech economic centers throughout the United States, Silicon Valley continues to be the leading high-tech hub because of its large number of cutting-edge entrepreneurs, engineers and venture capitalists. Geographically, Silicon Valley encompasses the northern part of the Santa Clara Valley and adjacent communities, though the term is often used when referring to the Santa Clara Valley as a whole.
