19．A knock at the door again!It was the third time someone _____ me that evening．（　　）

	A．	has interrupted		B．	had interrupted
	C．	interrupted		D．	would have interrupted

分析门口又有敲门声，这是那晚第三次有人打扰我．

解答答案：B．
本句考查特殊句式：It be the first time （that）+完成时态．在"It be the first time （that）…"结构中，that分句中的谓语动词用完成时；具体的取决于前面be动词的时态，当be为is时后面用现在完成时；当be为was时，后面常用过去完成时．根据本句中的was故选B．

点评对于一些特殊句式，只要掌握熟练基本结构，正确作答是不成问题的．另如：
This is the third time that Mr Smoth has visited the Summer Palace．这是史密斯先生第三次游览颐和园．

7．In 1991，high in the mountains of Europe，hikers made a discovery：a dead man partly frozen in the ice．However，the police investigation soon became a scientific one．Carbon dating indicated that the man died over 5，300years ago．Today he is known as the Iceman and has been nicknamed"?tzi"for the ?tztal Alps where he was found．Kept in perfect condition by the ice，he is the oldest complete human body on the earth．
Scientists think he was an important person in his society．An examination of his teeth and skull tells us that he was not a young man．His arms were not the arms of a laborer．His dagger（匕首） was made of stone，but he carried a copper axe．This implies wealth，and he was probably from the upper classes．We know he could make fire，as a fire-starting kit was discovered with him．Even the food he had eaten enabled scientists to reason exactly where in Italy he lived．
But why did the Iceman die in such a high and icy place？There have been many theories．Some said he was a lost shepherd．Others thought he was killed in a religious ceremony．Over the years since he was found，tiny scientific discoveries have led to great changes in our understanding of the story of the Iceman．The newest scientific information indicates that he was cruelly murdered．"Even five years ago，the story was that he fled up there and walked around in the snow and probably died of exposure，"said Klaus Oeggl，a scientist at the University of Innsbruck in Austria．"Now it's all changed．It's more like a…crime scene．"
In June 2001，an X-ray examination of the body showed a small dark shape beneath the Iceman's left shoulder．It was the stone head of an arrow．It had caused a deadly injury that probably killed him very quickly．In 2003，an Australian scientist discovered the blood of four different people on the clothes of the Iceman．Did a bloody fight take place before his murder？Injuries on his hand and head indicate that this may be true．One theory，put forward by archeologist （考古学家） WalterLeitner，says that the Iceman's murder was the end of a fight for power among his people．However，this idea is certainly debatable．

66．What does"?tzi"refer toA．
A．the oldest perfectly preserved human body
B．the most famous tourist attraction?tztal Alps
C．an important discovery by the police of Europe
D．the person living in ?tztal Alps for a long time
67．After the examination of the Iceman，scientists believe thatC．
A．he died at an early age
B．he made a fire-starting kit
C．he had a higher social status
D．he was born at a village in Italy
68．According to Klaus Oeggl，the Iceman died fromD．
A．a serious diseaseB．a snow disaster
C．a religious faithD．a terrible murder
69．What is the passage mainly talking aboutC？
A．The life of ancient people in the AlpsMountains．
B．The cruel religious life of the Europeans in the past．
C．The discovery andpossiblecause of death of the Iceman．
D．The application of carbon dating technology to the Iceman．
