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(kāi)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.

There the bee will deposit what she has got into the mouth of one of her coworkers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the b. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only onetwelfth of a tea spoon of me. Alas, my good health is not guaranteed.
