问题     In 1791 the French nation, in the midst of a revolution, wished to break with the past, especially with those aspects of it which they considered【S1】______and useless. One of those was the【S2】______system of weights and measures in use. Not only was the system overtly complicated, but it also varied【S3】______from place to place.
    In constructing the new【S4】______, the French began by setting up a unit of distance equal to one forty millionth part of the earth’s circumference(圆周). Unfortunately, later measurements showed that the unit designed was not【S5】______that fraction, but they continued to use it.(Today the unit is defined simply as the distance between two marks on a platinum-iridium(铂金)bar kept in a suburb of Paris). The unit is the【S6】______, and the system of measurements based on this unit is the metric system, the system today used by scientists the world over.
    The metric system is built in units of ten, Greek prefixes showing multiples and Latin prefixes【S7】______fractions. The Greeks had no【S8】______for a number larger than ten thousand and the Romans had none for a number larger than one thousand, but the system was extended by【S9】______less specific words; for instance megameter(one million meters)is【S10】______from a Greek word that means simply"large".

B)standard                                           J)system

D)derived                                            L)traditional
E)type                                               M)meter
F)illogical                                          N)explaining
G)totally                                            O)exactly
H)classic
【S4】
选项
答案J
解析 上段说要废除旧的度量衡体系(system)，该句说“在建立新的度量衡时”，很显然缺system。
