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.

We think other things will, like shopping or TV. But South Korea is starting to challenge this opinion.
