　　GWD-13-Q34:

　　Which of the following, if true, would most weaken the author’s conclusion in lines 25-30?

　　A. New research reveals that the number of species of birds and parasites that prey on lepidoptera has dropped significantly in recent years.支持

　　B. New experiments in which the habitats of lepidoptera are altered in previously untried ways result in the shortening of lepidoptera population cycles.

　　In short, the evidence implies that these insect populations, if not self-regulating, may at least be regulated by an agent more intimately connected with the insect than are predatory birds or parasites.

　　C. Recent experiments have revealed that the nuclear polyhedrosis virus is present in a number of predators and parasites of lepidoptera.支持

　　D. Differences among the habitats of lepidoptera species make it difficult to assess the fects of weather on lepidoptera population cycles.

　　E. Viral disease is typically observed in a large proportion of the lepidoptera population.支持

　　--------------------------------------------------------------------------------

　　GWD-13-Q35:

　　It can be inferred from the passage that the mortality caused by agents such as predatory birds or parasites was measured in an attempt to

　　A. develop an explanation for the existence of lepidoptera population cycles

　　The common approach of studying causes of population cycles by measuring themortality caused by different agents, such as predatory birds or parasites, has been unproductive in the case of lepidoptera.

　　B. identify behavioral factors in lepidoptera that affect survival rates

　　C. identify possible methods for controlling lepidoptera population growth偏

　　D. provide evidence that lepidoptera populations are self-regulating

　　E. determine the life stages of lepidoptera at which mortality rates are highest

　　--------------------------------------------------------------------------------

　　GWD-13-Q36:

　　The primary purpose of the passage is to

　　A. describe the development of new techniques that may help to determine the driving force behind population cycles in Lepidoptera新观点中有阐述但不是文章主旨

　　B. present evidence that rutes a particular theory about the driving force behind population cycles in Lepidoptera不是文章重心

　　C. present a hypothesis about the driving force behind population cycles in Lepidoptera

　　D. describe the fluctuating patterns of population cycles in Lepidoptera

　　E. question the idea that a single driving force is behind population cycles in lepidoptera

　　--------------------------------------------------------------------------------

　　GWD-13-Q37:

　　According to the passage, bore the discovery of new techniques for detecting viral DNA, population ecologists believed that viral diseases

　　A. were not widely prevalent among insect populations generally

　　B. affected only the caterpillar life stage of Lepidoptera

　　C. were the driving force behind lepidoptera population cycles

　　D. attacked already declining caterpillar populations

　　For many years, viral disease had been reported in declining populations of caterpillars, but population ecologists had usually considered viral disease to have contributed to the decline once it was underway rather than to have initiated it.

　　E. infected birds and parasites that prey on various species of lepidoptera
