Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.（1）What does paragraph 3 talk about? A.s hard to set up expensive screening equipment like what39。 The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干擾)caused by two factors of objectsthe material and shape. Most dangerous objects such as weapons are usually metal or liquid, which have significant interference, researchers said.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，在法國凡爾賽宮召開的會議上，七個基本計量單位中的四個將被重新定義，其中包括對千克的重新定義。國際單位制是現(xiàn)時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)。根據(jù)第三段中的“it was the French who in 1799 made it law和The Syst232。根據(jù)第二段中的“The king39。 （1）考查推理判斷。me International d39。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. 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.2．犇犇閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。故選B。 （3）考查細(xì)節(jié)理解。故選A。destroy large areas of forests and pollute the faroff sea iceD.D.releasedanalyze all aspects of how northern fires influence climateB.large amou
