【正文】 因此蝙蝠與鳥不同，蝙蝠可以倒掛著。故選C。根據(jù)第二段中的 In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings…This makes coordinating (協(xié)調) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances.可推斷出，過去人們認為蝙蝠與鳥在飛行運動方式與鳥沒有區(qū)別，最近的研究發(fā)現(xiàn)，這是不正確的，故也是要糾正的，故選C。尤其是they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do可知蝙蝠與鳥的運動不同；第三段中的Another interesting characteristic of bat flight is the way in which bats landupside down! Unlike birds which touch down on the ground or on tree branches,…再一次說明了蝙蝠與鳥運動方式的不同。以前人們認為蝙蝠和鳥類在運動方面沒有什么區(qū)別，但現(xiàn)在的研究證明蝙蝠的構造不同于鳥類，它們的翅膀由前肢和后肢組成，它們自我調節(jié)能力好，可迅速改變飛行方向，或完全逆行，這是鳥類不容易做到的，而且蝙蝠飛行的另一個有趣特征是蝙蝠倒立著降落的！這不同于那些降落在地上或樹枝上的鳥。the ability to change the speed（4）According to the passage, which of the following is NOT true? A.the sense of flying heightC.the distance to the netsB.Differences in the eating habits of bats and birds.D. Another interesting characteristic of bat flight is the way in which bats landupside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force。根據(jù)最后一段中的“The objects recovered from the bottom of the sea likely came from the recent explosion for two main reasons.”可知，作者在最后一段是想給出支持猜測的理由。 （3）考查推理判斷。故選C。一場巨大的流星雨導致了在海中搜索的開始。Give reasons to support a guess.C.B.Plenty of natural resources.D.To recover the rock particles. The Nautilus is equipped with two remotely operated vehicles(ROVs), called Hercules and Argus. These robotic submarines help researchers find and collect materials from the seafloor. The fact that the particles landed in the ocean, instead of on land, means larger pieces may have survived and can be studied. For this reason, scientists decided to launch the first intentional search for meteorites from the ocean. Until the latest research, scientists had only accidentally discovered a small number of meteorites from drilling operations.6．犇犇閱讀理解 caused greenhouse gas emissions.”地球上三分之一的無冰區(qū)被用于農(nóng)業(yè)生產(chǎn)，根據(jù)一些估算，食物生產(chǎn)大約占到了人類造成的溫室氣體排放量的五分之一。takes a big toll on固定短語，“付出了巨大的代價”，故選B。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。t explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that.” 我們發(fā)現(xiàn)（營養(yǎng)膳食指南的）影響因國家而異，但總的來說，在影響力較大的國家，如果你遵循國家推薦的膳食指南，即使這些膳食并未明晰對環(huán)境的影響，或者大多數(shù)膳食沒有明確說明這一點，但是你對環(huán)境的影響會因為遵循指南而減輕。 （1）考查推理判斷。 new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.D.caused greenhouse gas with only a third of the ice173。t mention the diet explicitly for its impacts can be ignored.（2）What do the underlined words takes a big toll on Following a nationally remended diet can do good to our health.C.eating173。 Overall, in high173。 However, following dietary guidelines would reduce those impacts, especially in wealthy countries like the US.
