听力原文： Little by little, Americans are turning to solar power, tapping the strength of the sun for energy.
Solar energy is only in its infancy, however, sunlight has already been used for heating or cooling homes and office buildings in the sunny south. Experts say all signs point to the birth of the solar energy industry. Right now, an increasing number of companies are selling solar collector panels to heat and cool homes or to heat water. The glass and metal panels cost from ＄ 100 to more than ＄ 500 each, and the three or four bedroom homes usually require a dozen or more. They look like sandwiches, or very narrow flower boxes, 3 to 6 feet in width, 8 to 10 feet long, and 4 to 8 inches thick. They are usually placed in rooftops. Nobody knows how many have been sold, and in addition, many people have built their own units. It has been estimated that solar power equipment will be a ＄ 1.3 billion industry by 1995, and more a million homes will use sunlight for heat, air conditioning or to generate electricity, both in the cities and in countryside.

The islands were annexed by the US in 1898 and since then Hawaii's native peoples have fared worse than any of its other ethnic groups. They make up over 60 percent of the state's homeless, suffer higher levels of unemployment and their life span is five years less than the average Hawaiians. They are the only major US native group without some degree of autonomy.
But a sovereignty advisory committee set up by Hawaii's first native governor, John Waihee, has given the natives' cause a major boost be recommending that the Hawaiian natives decide by themselves whether to re-establish a sovereign Hawaiian nation.
However, the Hawaiian natives are not united in their demands. Some just want greater autonomy with the state—as enjoyed by many American Indian natives over matters such as education. This is a position supported by the Office of Hawaiian Affairs (OHA), a state agency set up in 1978 to represent to natives' interests and which has now become the moderate face of the native sovereignty movement. More ambitious in the Ka Lahui group, which declared itself a new nation in 1987 and wants full, official independence from the US.
But if Hawaiian natives are given greater autonomy, it is far from clear how many people this will apply to. The state authorities only count as native those people with more than 50 percent Hawaiian blood.
Native demands are not just based on political grievances, though. They also want their claim on 660,000 hectares of Hawaiian crown land to be accepted. It is on this issue that native groups are facing most opposition from the state authorities. In 1933, the state government paid the OHA USS 136 million in back rent on the crown land and many officials say that by accepting this payment the agency has given up its claims to legally own the land. The OHA has vigorously disputed this.
Hawaii's native minority refers to ______.
A．people of Filipino origin
B．the Ka Lahui group
C．people with 50% Hawaiian blood
D．Hawaii's ethnic groups
