Viewed from a star in some other comer of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow, Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds—which are all too small to be seen from such a distance-reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own.
(2) "If you looked at our solar system from far away, and you looked at the terrestrial planets--Mercury, Venus, Earth and Mars--one of the quickest ways to see that Earth is unique is by looking at the light curve," said Ed Turner, professor of astrophysics and a co-author of the study. "Earth has by far the most complicated light curve." The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet's atmosphere, looking at the change in light over time docs not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.
"Earth would put on a little show" means: as it spins, ______.
A．Earth is a more active planet than Venus and Mars
B．Earth reflects a brighter light curve than Venus and Mars
C．Earth shows oceans, deserts, forests and clouds, while Venus and Mars don't
D．Earth reflects sunlight in an ebb-and-flow manner

Despite the general negative findings, it is important to remember that all children who live through a divorce do not behave in the same way. The specific behavior. depends on the child's individual personality, characteristics, age at the time of divorce, and gender. In terms of personality, when compared to those rated as relaxed and easygoing, children described as temperamental and irritable have more difficulty coping with parental divorce, as indeed they have more difficulty adapting to life change in general. Stress, such as that found in disrupted families, seems to impair the ability of temperamental children to adapt to their surroundings, the greater the amount of stress, the less well they adapt. In contrast, a moderate amount of stress may actually help an easygoing, relaxed child learn to cope with adversity.
There is some relationship between age and children's characteristic reaction to divorce. As the child grows older, the greater is the likelihood of a free expression of a variety of complex feelings, an understanding of those feelings, and a realization that the decision to divorce cannot be attributed to any one simple cause Self-blame virtually disappears after the age of 6, fear of abandonment diminishes after the age of 8, and the confusion and fear of the young child is replaced in the older child by shame, anger, and self-reflection. Gender of the child is also a factor that predicts the nature of reaction to divorce, the impact of divorce is initially greater on boys than on girls. They are more aggressive, less compliant, have greater difficulties in interpersonal relationships, and exhibit problem behaviors both at home and at school. Furthermore, the adjustment problems of boys are still noticeable even two years after the divorce.
Girls' adjustment problems are usually internalized rather than acted out, and are often resolved by the second year after the divorce. However, new problems may surface for girls as they enter adolescence and adulthood. How can the relatively greater impact of divorce on boys than on girls be explained？ The greater male aggression and noncompliance may reflect the fact that such behaviors are tolerated and even encouraged in males in our culture more than they are in females. Furthermore, boys may have a particular need for a strong male model of self-control, as well as for a strong disciplinarian parent. Finally, boys are more likely to be exposed to their parents' fights than girls are, and after the breakup, boys are less likely than girls to receive sympathy and support from mothers, teachers, or peers.
Temperamental, irritable kids have difficulty adapting to parental divorce because
A．they care too much about the life change.
B．the great stress of their families diminishes their ability.
C．they tend to lose temper easily and are sensitive to the life change.
D．they are faced with more parents' fights than the relaxed, easygoing children.

Too much metal in the soil is considered pollution. Yet too little metal in a person's diet can cause health problems. An American scientist says the answer to both problems may be plants that take up large amounts of metal in their tissues.
David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals.
In recent years, scientists have shown interest in using such plants to clean up harmful waste materials. Professor Salt says such plants also could be used to improve people's diets or even to create foods that fight cancer.
Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is blamed for health problems in many developing countries. Children and pregnant women are mostly affected.
Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that contain minerals needed for good health.
For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants.
Locoweed, which is a common plant in the western U.S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil.
Many people take pills to add important minerals or vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form.
The scientist says his team would like to develop a vegetable crop high in selenium. He wants to create an anti-cancer product in the foods we already eat.
According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______.
A．clean polluted soil and cure disease like cancer
B．clean up harmful waste materials in soil and improve people's diet
C．produce large number of micronutrients such as iron and zinc
D．create food with important minerals or vitamins
