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。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball.

This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling. 【點評】本題考點涉及細節(jié)理解，推理判斷和段落大意三個題型的考查，是一篇科教類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。根據(jù)第四段中的“By 2016 there were approximately 150 million tons of plastic in the world39。Fly over it.（4）Which of the following ideas does Liparts agree with?
