Those baby-faced people now have another reason to be smug: a new Danish study says looking young （1）______ means a longer life. Research suggests that people who look younger than their years also live longer.
In 2001, Danish researchers （2）______ physical and cognitive tests on more than 1,800 pairs of twins over aged 70, as well as taking photos of their faces. Three groups of people who didn't know the twins' real ages guessed how old they were. The researchers then （3）______ how long the twins （4）______ over 7 years.
The experts found that people who looked younger than their （5）______ age were far more likely to survive, even after they （6）______ for other factors like gender and environment. The （7）______ the difference in perceived age within any twin pair, the more likely it was that the older-looking twin died first.
They also found a possible biological （8）______: people who looked younger also tended to have longer telomeres （端粒）, a key DNA （9）______ that is linked to aging. People with shorter telomeres are thought to age faster. In the Danish study, the more fresh-faced people had longer telomeres.
The authors said that perceived age, which is widely used by doctors as a general （10）______ of a patient's health, is a good biomarker of aging that predicts survival among people over age 70.

It seems you always forget—your reading glasses when you are rushing to work, your coat when you are going to the cleaners, your credit card when you are shopping...
Such absent-mindedness may be （1）______ to you; now British and German scientists are developing memory glasses that record everything the （2）______ sees.
The glasses can play back memories later to help the wearer remember things they have forgotten such as where they left their keys. And the glasses also （3）______ the user to “label” items so that information can be used later on. The wearer could walk around an office or a factory identifying certain （4）______ by pointing at them. Objects indicated are then given a （5）______ label on a screen inside the glasses that the user then fills in.
It could be used in （6）______ plants by mechanics looking to identify machine parts or by electricians wiring a （7）______ device.
A spokesman for the project said: “A car mechanic for （8）______ could find at a glance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could （9）______ accident black spots or dangers on the road.”
In other cases the glasses could be worn by people going on a guided tour, （10）______ points of interest or by people looking at panoramas where all the sites could be identified.

After a day's hard work, we need some sleep. During sleep, the fatigue of the body （1）______ and recuperation begins. The tired mind gathers new energy. Once awake, the memory improves, and annoyance and problems are seen in a better （2）______.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. （3）______ sleep sixteen to eighteen hours daily and, as they grow older, the （4）______ gradually diminishes. Young students may need twelve hours; university students may need ten. A worker with a（n） （5）______ demanding job may also need ten, whereas an executive worker under great pressure may manage on six to eight. Many famous people are reputed to have required little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently （6）______ only four to six hours a night.
Whatever your （7）______ need is, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep （8）______: a favorite hour, a favorite bed, a favorite position, and a formula you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours, nearly five days, （9）______ animals that kept awake for from five to eight days have died of exhaustion. The （10）______ for human beings is probably about a week.

When women do become managers, do they bring a different style and different skills to the job? Are they better, or worse, managers than men? Are women more highly motivated and （1）______ than male managers?
Some researches support the idea that women bring different attitudes and skills to management jobs, such as greater （2）______, an emphasis on affiliation and attachment, and a （3）______ to bring emotional factors to bear in making workplace decisions. These differences are seen to carry advantages for companies, because they expand the range of （4）______ that can be used to help the company manage its workforce （5）______.
A study commissioned by the International Women's Forum （6）______ a management style used by some women managers （and also by some men） that differs from the command-and-control style （7）______ used by male managers. Using this “（8）______ leadership” approach, “women encourage participation, share power and information, enhance other people's self-worth, and get others excited about their work. All these things reflect their belief that allowing （9）______ to contribute and to feel powerful and important is a win-win situation good for the employees and the organization.” The study's director predicted that “interactive leadership may （10）______ as the management style of choice for many organizations.”

The most precious fluid on earth is not oil, but water. There are few challenges as important as conserving the world's usable water and （1）______ clean drinking water and water for irrigation to those who need it. Yet this work is not getting done. Humans are depleting the earth's store of usable water at a rate that will soon （2）______ our food supply. Poor water management already kills millions of people a year and （3）______ hundreds of millions to hunger.
The technology exists to solve these problems. Providing （4）______ with drinking water and sanitation, for example, is easy to do and a cost-effective way to prevent deaths and disease. But because those who suffer are poor, their access to water is rarely a political （5）______. There is now a（n） （6）______ for progress. More than 100 water ministers from around the world, along with thousands of water experts from villagers to scientists, have gathered in the Netherlands. The （7）______ will be useful if it can persuade governments and international banks to pay more attention to （8）______ and fair distribution of water.
In 1980, the U.N. set a goal of safe drinking water for all by 1990. Because of international prodding, about two billion new people received clean drinking water over the （9）______ 14 years. A new （10）______ is urgently needed to spread these healthy gains, help poor farmers and conserve the world's precious supply of usable water.

Men who bottle up their anger at being unfairly treated at work are up to five times more likely to （1）______ a heart attack, or even die from one, than those who let their （2）______ show, a Swedish study has found.
The study followed 2,755 employed men who had not suffered any heart attacks from 1992 to 2003. At the end of the study, 47 （3）______ had either suffered an attack, or died from heart disease, and many of those had been found to be “covertly coping” with unfair （4）______ at work.
“After adjustment for age, socioeconomic factors, risk behaviors, job （5）______ and biological risk factors at baseline, there was a close-response relationship between covert coping and the risk of incident myocardial infarction or cardiac death,” the study's authors wrote. Covert coping was listed as “letting thing pass without saying anything” and “going away” （6）______ feelings of being hard done by colleagues or bosses.
Men who often used these coping techniques had a two to fivefold higher risk of developing heart disease than those who were more （7）______ at work, the study showed.
The researchers said they could not answer the question of what might be a particularly healthy coping （8）______ at work, but listed open coping behavior when （9）______ unfair treatment or facing a （10）______ such as “protesting directly,”“talking to the person right away,”“yelling at the person right away” or “speaking to the person later when things have calmed down.”
