Much of the energy that comes from the sun never reaches the earth's surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the earth's surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the earth's surface back to the earth. These gases act like the glass of a greenhouse in that they allow energy from the sun to enter but prevent energy form. leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. Dark-colored surfaces, such as dark soil or forest, absorb more energy.
According to the passage, the root cause for weather changes on the earth is
A．the atmosphere surrounding the earth
B．water from oceans and lakes
C．energy from the sun
D．greenhouse gases in the sky

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

Psychologists Paul Ekman, Robert W. Levenson and Wallace Friesen enrolled professional actors in their experiment because they have been trained both to recall emotions from the past and not to be self conscious or embarrassed when asked to pose. After they were hooked up to equipment that electronically recorded the activity of their involuntary nervous systems, the actors were not told how to feel. But they were, instructed to move muscles in their faces to create smile, frowns, and expressions of anger, fear, sadness, happiness, disgust and surprise.
Two major findings came out of the study, published in Science magazine. One is that heart rate and skin temperature--both under the control of the autonomic nervous system--vary according to facial expression. This suggests some form. of communication between the brain's motor cortex(皮层), which governs voluntary movements, and areas in the brain's hypothalamus(下丘脑) that, instead, deal with unconscious bodily reactions to stimuli.
The other finding is that, contrary to what had been expected, the facial expressions that convey anger, fear, sadness and disgust each produce a different, but typical pattern of response from the involuntary nervous system. Though the psychologists have not yet detected correspondingly specific patterns for the other emotions they studied, they expect to identify them eventually.
As importantly, says Ekman, the new discoveries may, in time, have practical consequences because they "open the door to exploring how emotions cause physical disorders, and offer the possibility of using facial expressions therapeutically(治疗地)."
Scientists discovered that people's emotions are______.
A．controlled by their facial expression
B．influenced by their facial expression
C．identical with their facial expression
D．contrary to their facial expression
