Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly.

They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine. The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS. 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。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。 （4）考查細節(jié)理解。國際單位制是現(xiàn)時世界上最普遍采用的標準度量衡單位系統(tǒng)，采用十進制進位系統(tǒng)。Unit233。根據(jù)第三段中的“it was the French who in 1799 made it law和The Syst232。故選D。根據(jù)第二段中的“The king39。故選B。 （1）考查推理判斷。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。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.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
