[单项选择]"We thought there was a future in nuclear power when no one else believed in it," says Anne Lauvergeon, chief executive of Areva. The French, government-owned company is building the first nuclear reactors to be constructed in Western Europe for nearly 20 years. With" no oil, no gas, no coal and no choice", France decided to go nuclear in 1974, and today about 80% of its electricity is generated by 59 nuclear plants across the country. But even France became pessimistic about nuclear power: it stopped building new reactors at the end of the 1980s and in 2002 a government report called the industry a" monster without a future".
How things have changed. Nuclear power is back in favor, thanks to fears about oil supplies, energy security and global warming. France is ready to develop its expertise into a significant export. Its president, Nicolas Sarkozy, considers the sale of nuclear power to be central to his diplomacy: it is a symbol of France’s technical power and a reaffirmation

despises and condemns the vices which one does not happen to possess. I am
indeed not a severe man, nor would I permit myself to become intolerant of those
failings which I share with others. But, having no particular temptation to be
untruthful, I find myself believing that when one comes to think of it, truth is
the major virtue and lying the most blameworthy of all the vices. I should like,
therefore, to get my mind a little clearer on the truth question. I flatter
myself, as I have said, that I am a truthful man: a man who, when he tells a
lie, is careful not to forget that he has done so, and. who takes infinite
precautions to prevent his being found out. This, in the end, is the only test
by which you can distinguish the liar from the man of truth. The latter who is
bothered by untruthfulness, is worried and anxious. The real liar, however, is
merely amused: he doesn’t mind in the l
A. the former feels uneasy about the untruths he happens to tell
B. the latter takes great care to hinder his untruths from being exposed
C. the former is willing to confess his untruthfulness when he tells a lie
D. the latter is only amazed if his untruths are disclosed
