The center of American automobile innovation     1    (move) 2,000 miles away in the past decade. It has migrated from Detroit to Silicon Valley,     2     self-driving vehicles are coming into life.

In a bid to take production back to Detroit, Michigan lawmakers have introduced legislation   that could make their state     3    (good) place in the country, if not the world, to develop self-driving vehicles and put them on the road.

“Michigan’s role in auto research and development is under attack from several states and countries which desire to take     4     place of our leadership in transportation. We can’t let happen,” says Senator Mike Kowall, the lead sponsor of four bills     5    (recent) introduced.

If all four bills pass as     6    (write), they would represent an important update of Michigan’s 2013 law that allowed the testing of self-driving vehicles in limited conditions. Manufacturer would have nearly total freedom     7    (test) their self-driving technology on public roads. They would     8    (allow) to send groups of self-driving cars on cross-state road trips, and even set on-demand rows of self-driving cars, like the one General Motors and Lyft are building.

Lawmakers in Michigan clearly want to make the state ready for the commercial use of self-driving technology.     9    contrast, California, home of Silicon Valley, proposed far more restrictive rules that would require human drivers be ready for the commercial     10    (apply) of self-driving technology.

2 . Federal laws have been in place to protect archaeological (考古学的) resources for more than a century.    1    However, decades later the law's language was deemed too vague to offer adequate protection from looters (劫掠者) and vandals ( 故意破坏公物者). In response, the Archaeological Resources Protection Act was enacted in 1979.    2    

Yet theft, vandalism, and looting continue to pose serious threats to our cultural resources, and land managing agencies, tribal communities, and others are faced with the challenge of protecting heritage sites. A 2010 National Park Service report revealed that more than 3,000 cases of vandalism and looting on federal lands were documented within a 3-year period, and many more are likely unreported. Destructive behaviors range from the harmful act of artifact collecting to the criminal activity of looting and grave robbing.    3    For example, some artifacts (古手工艺品) are removed from their contexts by collectors.

Ancestral sites and surface artifacts are abundant in the Southwest. These material remains maintain connections to ancient traditions and cultural identity.    4     Acts of theft and destruction cause real and lasting harm, depriving us of the opportunity to learn about and appreciate the history of our land. Looters disturb human remains and steal from graves for financial gain, thereby negatively impacting the spiritual health and wellbeing of Native American communities.     5    A shared goal among many archaeologists is to increase public awareness to help stop this destruction, but we are only subset of preservation- minded groups. The support of other parties like tribal communities, environmental advocates and historians is necessary to protect archaeological resources and sacred landscapes.
