Life has changed in Mexico City．Streets normally filled with people are empty．One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people．It's swine （猪）flu that has made life in Mexico City grind to a halt （慢慢停了下来）．

Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30．It has sent a wave of alarm around the world．Governments are trying to find ways to prevent further out-breaks．The World Health Organization has raised its swine flu global threat level to five out of six．

People may be familiar with bird flu, but they know little about swine flu．Swine flu is a contagious（传染性） respiratory（呼吸的）disease in pigs．It is caused by a type-A influenza virus．

Humans can also catch swine flu．The virus causes regular outbreaks in pigs, but people usually do not catch it．However, there have been cases of the virus spreading to people, and then from one person to another．

The symptoms of swine flu are similar to the common flu．They include fever, lethargy （无精打采）, lack of appetite, coughing, runny nose, sore throat, nausea（恶心）, and vomiting （呕吐）．The high proportion of young adults among the deaths is one of several mysteries about this virus．Most of the dead had lung damage．What caused it is not yet known．

The virus spreads the same way the common flu does．When an infected person coughs or sneezes around another person, the latter is put at risk．People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes．

There are medicines to treat swine flu．Doctors suggest using anti - viral drugs．They keep the virus from reproducing inside the body．

And there are vaccines for it now, several everyday steps can also help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it．

People may worry that they will get swine flu from eating or preparing pork．In fact, you cannot catch the virus from pork products if they have been properly prepared and cooked．Cooking food at temperatures of 71℃ kills the virus．

A story from the Bible tells of old Babylon, where the men decided to build a tower that would touch the sky．But God was unhappy, and he made them speak different languages．They couldn’t understand each other, so their dream never came true．

Yet the dream remains alive: if all men speak the same language, they can do anything．L．L．Zamenhof from Poland was among the men who pursue this dream．He developed Esperanto（世界语）between 1877 and 1885．

As the most successful man-made world language, it is spoken by over two million people around the world．Last month, the World Esperanto Congress（大会）, dealing with language rights, ended in Sweden．The 2004 conference will be held in Beijing．Most Esperanto speakers are in Central and Eastern Europe and in East Asia, particularly Chinese mainland．

Esperanto has two advantages．First, it’s easy．Each letter has exactly one sound and there are just 16 basic grammar rules．The second advantage is that it belongs to no one country．But Esperanto has only reached a small number of people compared with natural languages widely used around the world-such as English or Chinese．While these languages are deeply connected with their nations and cultures, Esperanto doesn’t have this background．

Will Esperanto really become a global language? It remains a question．

Between their crazy schedules and upside-down circadian（昼夜节律的） rhythms, teens have always been somewhat sleep-deprived（剥夺）．Now technology is making it worse．
Teens are not just texting, instant-messaging and surfing Facebook all day; they’re sleeping with their cell phones or laptops, too．Or rather, not sleeping．And doctors and parents, many of whom raised in an era when phones were attached to walls, are concerned．
“So many teens are having sleep issues, and parents aren’t necessarily regulating the use of the electronic devices enough,” says Margie Ryerson, a therapist．“It’s impossible to wind down and relax the body, the mind, the senses and be ready to fall asleep．”
“We all know teens don’t get enough sleep in general,” says San Francisco．“As long as parents allow teens to have these devices in their bedrooms at night, teens will be tempted（诱惑） to use them．”… Teens would socialize 24/7 if they could．
Ryerson calls it the CNN syndrome of teenhood— round-the-clock reports on breaking news about everything, from homework to wardrobe choices to ice-cream cravings．
Sleep deprivation is linked to memory and concentration problems, anxiety and depression, and moodiness．“Many people assume these problems arise directly from adolescence, which is not really true,” he says．“The real issue is sleep deprivation．Late-night texting can certainly make the situation worse．”
“The psychology behind this constant contact is certainly understandable,” Ryerson says．“It comes from wanting to avoid being left out．They won’t be considered important and significant in their peer group, if they don’t know what’s going on．If they’re on top of everything, they belong,” she says．
“What helps, at least for younger kids,” says Ryerson, “is parental involvement．If all of their friends are all able to text into the early hours of the night, it is hard for a middle or high schooler to set the limit themselves．Often they appreciate parents stepping in．”
“As parents, we want our kids to be happy, healthy and responsible,” she says, “and the most necessary requirement for achieving balance is to first take care of ourselves physically — eating well, exercising and getting enough sleep．”
【小题1】According to Ryerson, it seems that ____．

A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.
The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.
An addiction that doesn’t discriminate(歧视)
“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.
Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.
Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.
In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.
“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.
【小题1】The study led by Professor Mark Weiser shows that            .

A recent survey made by BUPA, an international healthcare provider, shows that 54 percent of Chinese people aged between 45 and 54 consider themselves old, while 28 percent say that the thought of getting old upsets them. 25 percent are afraid of getting old, and a third worry about life in old age.
BUPA made the survey among 12,262 people from 12 countries over 2 months, starting in June 2010. The survey shows that 72 percent of international participants(参加者) aged over 65 don’t feel old and that 67 percent still feel healthy. On the other hand, 65 percent of Chinese feel old even before reaching 60. About one third of those surveyed in China said they have enough savings(存款), and 46 percent are insured(参加保险). Around 60 percent of the Chinese participants hope they will be taken care of by family members.
According to the survey, the French hold the most positive attitude towards getting old, with 32 percent of them considering age 80 and up old. 17 percent of Brazilians look forward to old age, compared with 3 percent globally. Indians are not bothered by old age, as 70 percent said that they don’t feel that they will be affected by old age and 71 percent say they have already made preparations for this stage of life. The illnesses that most people around the world are worried about are cancer and Alzheimer’s disease.
【小题1】According to the survey, many Chinese people surveyed feel old before they are ______.
