【正文】 passage? A.The opossum fakes its death to avoid being targeted by predators.C.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.B.C.D. （1）考查細(xì)節(jié)理解。Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對(duì)食物不那么感興趣，從而保護(hù)自己免受捕食者的傷害。 （2）考查細(xì)節(jié)理解。Opossum (負(fù)鼠)部分中的“In order to bee ‘dead’, they don39。故選B。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團(tuán)。眼睛，并在攻擊者身上留下可怕的氣味。故選C。3．犇犇閱讀下列短文，從每題所給的A、B、C和D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定義) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆樹) seed.s foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at , around a centimeter shorter than the Belgic foot, used in England until , Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (統(tǒng)一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.me International d39。s (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shakeup yet.s measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常數(shù)).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us? went before libra in measurement. things used to be adopted as measures. were accepted as measures by the Romans. measurement systems were gradually formed.（2）How does the author develop the second paragraph? time order. analysis. space order. parison.（3）Which of the following countries used SI as an official measurement? ....（4）What will the world39。 （1）考查推理判斷。故選B。根據(jù)第二段中的“The king39。故選D。根據(jù)第三段中的“it was the French who in 1799 made it law和The Syst232。Unit233。國(guó)際單位制是現(xiàn)時(shí)世界上最普遍采用的標(biāo)準(zhǔn)度量衡單位系統(tǒng)，采用十進(jìn)制進(jìn)位系統(tǒng)。 （4）考查細(xì)節(jié)理解。s measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units...will follow the other three...in being redefined in terms of the values of physical constants”可知，在法國(guó)凡爾賽宮召開的會(huì)議上，七個(gè)基本計(jì)量單位中的四個(gè)將被重新定義，其中包括對(duì)千克的重新定義。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。 This question was raised after a group of penguins were saved from an icy gully (峽谷) in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young.

They built a slope（斜坡）so that a few of the penguins could save themselves.”和第三段中的“The case has taken the international media by storm”可知，從峽谷中救出企鵝這一事件引起了大家的熱議。 （2）考查推理判斷。m so glad.
