  [解析] 本题考查推断题;根据文章第二段“At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection。”可知新的声音技术可以给人们带来便利性,而后第三段又论述了这一技术会使现存自动语音电话问题更加糟糕,由此可推出技术有两面性,是把双刃剑。故正确答案是B。

  D

  By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study。

  At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton。 Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface。 Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton。 Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance。

  Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen。 When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate。 But phytoplankton are vulnerable to the ocean’s warming trend。 Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients。

  Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century。 In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur。 The model projects that currently blue areas with little phytoplankton could become even bluer。 But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener。 “Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing。”

  And why does that matter? Phytoplankton are the base of the food web。 If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive。” Those kinds of changes could affect the food chain。

  Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes。 “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet。”

  42。 What are the first two paragraphs mainly about?

  A。 The various patterns at the ocean surface。

  B。 The cause of the changes in ocean colour。

  C。 The way light reflects off marine organisms。

  D。 The efforts to fuel the growth of phytoplankton。

  42。

  [答案] B
