[单项选择] Air France SA said Monday that its second-quarter net profit fell 35 percent to €57 million ($57.4 million), but sales were steady and operating profit surged.
Earnings before interest and tax, a measure of operating income, gained 86 percent to €141 million as fuel costs fell and cargo traffic rose. Air France has been hurt less than rivals such as British Airways PLC and Lufthansa AG by the slowdown on North Atlantic routes following the war on Iraq in 2003 because it has fewer flights in that market.
Net income fell as the airline paid deferred taxes that came due. Sales rose 0.9 percent to €3.2 billion. The carrier lost about €80 million in revenue because of a four-day strike by pilots in September. An accord was reached tying future pay increases to inflation. The carrier said that first-half fuel costs fell 15 percent to €680 million. Cargo traffic rose 11 percent in the second quarter, while passenger traffic rose 1.1 percent. The airline’’s shares gained 87 cents

[单项选择]It happens to us all, however hard we may try to delay the process—we grow old. Surgery may remove wrinkles (皱纹), skin which has become less firm may be tightened by a surgical operation on the face, and hair-dressers may dye grey hair a more youthful color, but we cannot remain young forever.
Advances in medicine have made it possible for more people to stay alive longer. However, what is important is the quality of life, and people age differently. Some people remain quite well and able to look after themselves when they get old, but others of the same age are not so lucky. They have to go into a nursing home in order to receive adequate care.
The worst aspect of ageing is that often the mind becomes less alert. As people grow older, they often experience loss of short-term memory, although they may well be able to recall quite easily events that happened long ago. Later they may suffer from dementia (痴呆), a disease which gets gradually worse.

I don’t think there is anything wrong with your blood. The key to your problem is that long nap after dinner.
If you didn’t sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn’t nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day.
