Molting (换羽,脱毛) is one of the most involved processes of a bird's annual life cycle. Notwithstanding preening (梳理羽毛) and constant care, the marvelously complex structure of a bird' s feather inevitably wears out. All adult birds molt their feathers at least once a year, and upon close observation, one can recognize the frayed (磨损的), ragged appearance of feathers that are nearing the end of their useful life.
Two distinct processes are involved in molting. The first step is when the old, worn feather is dropped, or shed. The second is when a new feather grows in its place. When each feather has been shed and replaced, then the molt can be said to be complete. This, however, is an abstraction (抽象的概念) that often does not happen: incomplete, overlapping, and arrested molts are quite common.
Molt requires that a bird find and process enough protein to rebuild approximately one-third of its body weight. It is not surprising that a bird in heavy molt often seems listless and unwell. But far from being random, molt is controlled by strong evolutionary forces that have established an optimal time and duration. Generally, molt occurs at the time of least stress on the bird. Many songbirds, for instance, molt in late summer, when the hard work of breeding is done but the weather is still warm and food still plentiful. This is why the woods in late summer often seem so quiet, when compared with the exuberant (充满活力的) choruses of spring.
Molt of the flight feathers is the most highly organized part of the process. Some species, for example, begin by dropping the outermost primary feathers on each side (to retain be dance in the air) and wait until the replacement feathers are about one-third grown before shedding the next outermost, and so on. Others always start with the innermost primary feathers and work outward. Yet other species begin in the middle and work outward on both weeks while the replacement feathers grow.
The passage mainly discusses how______.
A．birds prepare for breeding
B．bird feathers differ from species
C．birds shed and replace their feathers
D．birds are affected by seasonal changes

Young Female Chimps Outlearn Their Brothers
Young female chimps are faster and better learners than young male chimps, suggests a new study, echoing learning differences seen in human girls and boys
While young male chimps pass their time playing, young female chimps carefully study their mothers. AS a result, they learn how to fish for tasty termite snacks over two years before the boys.
Elizabeth Lonsdorf, now at Lincoln Park Zoo in .Chicago, US, and colleagues at the University of Minnesota, Saint Paul, spent four years watching how young 'chimpanzees in the Gombe National Park in Tanzania learned "cultural behavior".
The sex differences in learning behavior. were "consistent and strikingly apparent", says the team. The researchers point out that similar differences are seen in human children with regard to skills such as writing. "A sex-based learning differences may therefore date back at least to the last common ancestor of chimpanzees and humans," they write in the journal Nature.
Chimps make flexible tools from vegetation and then insert them into termite mounds, extract them and then munch the termites clinging onto the tool The researchers used video cameras to record this feeding behavior. and found that each chimp mother had her own technique, such as how she used tools of different lengths;
Analysis of the six infants whose ages were known showed that girl chimps were an average of 31 months old when they succeeded in fishing out their termites, Where the boy chimps were aged 58 months on average. Females were also more skillful at getting out more termites with every dip and used techniques similar to their mothers while males did not.
Instead of studying their mothers, the boy chimps spent a significantly greater amount of time frolicking around the termite mound. Behaviors such as playing or swinging might help the male infants later in life when typically male activities like hunting or fighting for dominance become important, suggest the researchers.
Lonsdorf adds that there are just two main sources of animal portein for chimps -- the termites or colobus monkeys. "Mature males often hunt monkeys up trees, but females are almost always either pregnant or burdened with a clinging infant. This makes hunting difficult," she says. "Adult females spend more time fishing, for termites than males." So becoming proficient at termite fishing could mean adult females eat better. "They can watch their offspring at the same time. The young of both sexes seem to pursue activities related to their adult sex roles at a very young age."
Why do young female chimps learn faster than young male chirnps at fishing for termites？
A．Because young female chimps don't play with their brothers.
B．Because young female chimps begin to study their mothers earlier.
C．Because young male chimps never learn to fish for termites.
D．Because young male chimps are not interested in termites.

The editor of Exciting Comics, Ed O' Donnell, was important in extending the success of this marketing drive. Here organized comic drawing to encourage artists' innovation.

He abandoned the low-cost budget publication, a step considered risky to his peers in the publication industry; however, his begin environment for artistic creation eventually proved successful. Kenny Bar was one of the artists that helped spawn the most innovative titles to come out of Exciting Comics.

This revolutionary idea laid the foundation for the now thriving market for sophisticated adult-oriented comic books.
What is the best title for this passage？
A．Kenny Barby' s Contribution to the World of Comics.
B．The Publishing World of Edward O' Donne Ⅱ.
C．The Birth of the Comic Book.
D．The Comic Book Since World War Ⅱ.
