(2)Only when I left my parents for Italy ________ how much I loved them.
A.I realized
B.I had realized
C.had I realized
D.did I realize
解析:选D。考查Only+时间状语置于句首引起句子的部分倒装。因此排除A、B。又由于realize在left之后,故不用过去完成时。
COPERNICUS’ REVOLUTIONARY THEORY
Nicolaus Copernicus was frightened and his mind was confused.Although he had tried to ignore them,all his mathematical calculations led to the same conclusion: that the earth was not the centre of the solar system.Only if you put the sun there did the movements of the other planets in the sky make sense.Yet he could not tell anyone about his theory as the powerful Christian Church would have punished him for even suggesting such an idea.They
believed God had made the world and for that reason the earth was special and must be the centre of the solar system.
The problem arose because astronomers had noticed that some planets in the sky seemed to stop,move backward and then go forward in a loop.Others appeared brighter at times and less bright at others.This was very strange if the earth was the centre of the solar system and all planets went round it.
Copernicus had thought long and hard about these problems and tried to find an answer.He had collected observations of the stars and used all his mathematical knowledge to explain them.But only his new theory could do that.So between 1510 and 1514 he worked on it,gradually improving his theory until he felt it was complete.
In 1514 he showed it privately to his friends.The changes he made to the old theory were revolutionary.He placed a fixed sun at the centre of the solar system with the planets going round it and only the moon still going round the earth.He also suggested that the earth was spinning as it went round the sun and this explained changes in the movement of the planets and in the brightness of the stars.His friends were enthusiastic and
encouraged him to publish his ideas,but Copernicus was cautious.He did not want to be attacked by the Christian Church,so he only published it as he lay dying in 1543.
Certainly he was right to be careful.The Christian Church rejected his theory,saying it was against God’s idea and people who supported it would be attacked.Yet Copernicus’ theory is now the basis on which all our ideas of the universe are built.His theory replaced the Christian idea of gravity,which said things fell to earth because God created the earth as the centre of the universe.Copernicus showed this was obviously wrong.Now people can see that there is a direct link between his theory and the work of Isaac Newton,Albert Einstein and Stephen Hawking.
哥白尼的革命性理论
尼古拉·哥白尼被吓坏了,他心里非常困惑。虽然他曾经努力不去理睬那些数字,然而他所有的计算都得出一个同样的结论:地球不是太阳系的中心。只有把太阳放在中心位置上,天空中其他行星的运动才能讲得通。然而他不能告诉任何人他的理论,因为强大的基督教甚至会因为他提出这样一个想法而惩罚他。他们相信是上帝创造了世界,因此地球是很特殊的,它一定是太阳系的中心。
问题就随之产生了,因为天文学家们曾经注意到天空中的某些行星好像能停下来,向后运行,然后再向前做环形运动。其他行星有时好像亮些,有时好像又暗一些
