2、bly, are very often asked. Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the bes
3、t reason for exploring space is this genetic tendency to expand wherever possible.Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowled

37、s【参考答案】1115、11-20 ADABD Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes.

38、nt of Africans, researchers at Pennsylvania State University report in the latest issue of Science.Scientists have changed the color of a dark-striped zebrafish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined
39、by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.However,
40、 Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.But when modern humans leave Afr
