A.s ocean will be, on average, at least 60cm higher by the end of the century. However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg? A. The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change, she said. It is important that we get there quickly before the undersea environment changes as sunlight enters the water. A team of international scientists is due to set off for the world39。To study how the iceberg was formed.B.It is as big as London.B.冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學(xué)家提供了研究未知的海洋生物的機會。根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng)，可知選D。 A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them.

However, following dietary guidelines would reduce those impacts, especially in wealthy countries like the US. Most of the reductions e from meat and dairy, which have an outsized impact on land use and pollution, and are a major source of greenhouse gases.(That39。t mention the diet explicitly for its impacts can be ignored.（2）What do the underlined words takes a big toll on new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.D.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。takes a big toll on固定短語，“付出了巨大的代價”，故選B。4．犇犇閱讀理解 up isn39。If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding itD.Shining colors as a sexual strategy【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了彩虹色有助于生物隱藏。根據(jù)最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我們的目標上驚人的彩虹表面在視覺上打破了原本可以辨認的目標形狀，這使得它們很難區(qū)分。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was
