Science develops through objective analysis, instead of
through personal belief. Knowledge gained in science accumulates as time goes
by, building on work performed earlier. Some of this knowledge-such as our
understanding of numbers-stretches back’ to the time of ancient civilizations,
when scientific thought first began. Other scientific knowledge such as
our understanding of genes that cause cancer or of quarks (the smallest known
building block of matter) -dates back less than 50 years. However, in all fields
of science, old or new, researchers use the same systematic approach, known as
the scientific method, to add to what is known.
41__________. For example, in 1676, the English physicist Robert Hooke discovered that elastic objects, such as metal springs, stretch in proportion to the force that acts on them. Despite all the advances that have been made in physics since 1676, this simple law Still holds true. 42__________.

A.正确 B.错误 [单项选择]The planet’s wild creatures face a new threat—from yuppies (雅皮士), empty nesters and one parent families.
Biologists studying the pressure on the planet’s dwindling biodiversity today report on a new reason for alarm. Although the rate of growth in the human population is decreasing, the number of individual households is exploding. Even where populations have actually dwindled in some regions of New Zealand, for instance—the numbers of individual households has increased, because of divorce, career choice, smaller families and longer lifespan. Jianguo Liu of Michigan State University and colleagues from Stanford University in California report in Nature, in a paper published online in advance, that a greater number of individual households, each containing on average fewer people, meant more pressure on natural resources. Towns and cities began to sprawl as new homes were built. Each household needed fuel to heat and light it; each household required its own plumbin A. the increase of human population leads to more destruction of the natural world B. the decrease of animal population results from the dwindling biodiversity in the natural world C. the planet’s biodiversity is also related to the number of households D. the planet’s biodiversity relies on the balanced increase of larger and smaller households 我来回答: 提交
