Questions 81 to 85 are based on the following passage：
　　It's never easy to admit you are in the wrong. Being human, we allneed to know the art of apologizing. Look back with honesty and think howoften you've judged roughly, said unkind things, pushed yourself ahead atthe expense of a friend. Then count the occasions when you indicatedclearly and truly that you were sorry. A bit frightening, isn't it？ Frightening because some deep wisdom in us knows that when even a smallwrong has been committed, some mysterious moral feeling is disturbed； andit stays out of balance until fault is acknowledged and regret expressed.
　　I remember a doctor friend, the late Clarence Lieb, telling me abouta man who came to him with a variety of signs： headaches, insomnia andstomach trouble. No physical cause could be found. Finally Dr. Lieb saidto the man, “Unless you tell me what's worrying you, I can't help you.”
　　After some hesitation, the man confessed that, as executor of hisfather's will （ò？？？）, he had been cheating his brother, who lived abroad,of his inheritance. Then and there the wise old doctor made the man writeto his brother asking forgiveness and enclosing a cheque as the firststep in restoring their good relation. He then went with him to the mailbox in the corridor. As the letter disappeared, the man burst into tears.“Thank you,”he said,“I think I'm cured.”And he was.
　　A heartfelt apology can not only heal a damaged relationship but alsomake it stronger. If you can think of someone who deserves an apology fromyou, someone you have wronged, or judged too roughly, or just neglected,do some-thing about it right now.

　　Questions 86 to 90 are based on the following passage：
　　In 1791 the French nation, in the midst of a revolution, wished to breakwith the past, especially with those aspects of it which they consideredillogical and useless. One of those was the traditional system of weightsand measures in use. Not only was the system overtly complicated, but italso varied widely from place to place.
　　In constructing the new system, the French began by setting up a unitof distance equal to one forty-millionth part of the earth's circumference（？2？ü）。 Unfortunately, later measurements showed that the unit designed wasnot exactly that fraction, but they continued to use it. （Today the unit isdefined simply as the distance between two marks on a platinumiridium （2？？e）bar kept in a suburb of Paris）。 The unit is the meter, and the system ofmeasurements based on this unit is the metric system, the system today usedby scientists the world over.
　　The metric system is built in units of ten, Greek prefixes showingmultiples and Latin prefixes showing fractions. The Greeks had no word for anumber larger than ten thousand and the Romans had none for a number largerthan one thousand, but the system was extended by using less specific words；for instance megameter （one million meters） is derived from a Greek word thatmeans simply“large”。

　　89. At first the basic unit was to equal _______. A） one-millionth part of the earth's circumference B） the distance between two marks on a platinumiridium bar C） one forty-millionth part of the earth's circumference D） one forty-millionth part of the earth's diameter
　　90. When the basic unit was proved inexact, the French _______. A） reconstructed the entire system B） changed to another system C） redefined the meter D） returned to the traditional system of measurements
