Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia.
By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death.
The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit
from human to human.
"In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO.
Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico.
The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency.
Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems.

查看习题详情和答案>>CHICAGO （Reuters） - Smoking not only can wrinkle （起皱纹） the face and tarn it yellow—it can do the same to the whole body, researchers reported on Monday．
The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body—even skin protected from the sun．
"We examined non - facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr．Yolanda Helfrich of the University of Michigan, who led the study, said in a statement．
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers．Similar findings were seen in participants aged 45 to 65 years," Helfrich "s team added in their report．
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms． They ranged, in age from 22 to 91 and half were smokers．Independent judges decided how wrinkled each person' s skin was．
When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich ' s team wrote．
Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light．
The report did not discuss die mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels （血管） beneath the skin to constrict （紧缩）, reducing blood supply to the skin．
Smoking can also damage the connective tissue that supports both die skin and the internal organs,．
When your skin is exposed to sunlight long, it-becomes all of the following but _____．
A．flexible B．coarse C．rough D．discolored
How wrinkled a person's skin is doesn't relate to _____．
A．the number of cigarettes a person smokes．
B．the kind and characteristics of skin
C．how long a person smokes
D．how long skin is under sunlight
From the passage smoking results in skin aging mainly because _____.
A．it will lower blood supply to skin
B．it can make you feel tired
C．it can make skin come off
D．it can make blood run faster
The main purpose of the passage is to _____．
A．inform people about the result of the study
B．advise people how to protect skin
C．warn people not to smoke again
D．introduce a new way of avoid skin aging
查看习题详情和答案>>EBay will launch an online group gift-buying service today designed to make it easier for several people to chip in, buy and pay for gifts using their social-network and e-mail contacts．
EBay North America Vice President Christopher Payne says it is going to be a major step forward in social commerce, which is the still-small practice of selling products through social networks．Online retail experts aren't as certain, but eBay says the new tool makes it easier for friends and relatives to chip in （凑钱） for gifts because it eliminates the headache of collecting contributions．It can also be used for family members to pitch in to buy, say, an expensive child seat for a mother．
Anything on eBay that's available immediately, rather than up for bid, can be purchased this way starting today at groupgifts．eBay．com．If members of an extended family wanted to buy a gift for one member, one person would choose a gift — or have one recommended by eBay — and invite family members to chip in using Facebook or e-mail．Those who wanted to join in would choose an amount to contribute （or agree to pay a requested amount） and pay using either PayPal or a credit card．They could also add a personal note．
If enough people don't chip in, the organizer can ask people to contribute more or choose a less expensive gift．
"I see myself using this most in cases when I typically might not buy someone what they want because of price," says Nitzan Shaer of Boston, who was part of an online test of the site．
EBay, with its 200 million products, millions of sellers and mobile commerce proficiency, is a logical place to pull together the products, groups of buyers and payment tools, Payne says．
At least 12 sites, such as FrumUs．com and eDivvy．com, facilitate （便于,利于） group purchases but don't sell products．Although a handful of retailers, including Victoria's Secret and 1-800-Flowers, sell products through Facebook, Payne says he expects social commerce will take off as rapidly as shopping using mobile devices．EBay did more than $600 million in sales on mobile devices last year and expects mobile sales to increase to $1．5 billion this year．
Although one in five consumers surveyed said they'd used Facebook for shopping in the past year, 88% said they would not be buying holiday gifts through a social network, mobile phone or smartphone．Of these, 26% were reluctant because of security or privacy concerns, and 20% were unclear about the benefits of using phones or Facebook to shop．
What procedure should be followed if your extended family intends to buy your grandpa an 80th birthday gift?
①Asking family members to contribute more money if enough members don’t chip in
②Choosing a gift at groupgifts．eBay．com
③Paying using PayPal or a credit card
④Contributing or agreeing to pay a requested amount of money via Facebook or e-mail
A．②-①-③-④ B．①-③-②-④
C．②-④-①-③ D．②-③-④-①

查看习题详情和答案>>The Sahara Festival is a celebration of the very recent past. The three-day event is not fixed to the same dates each year, but generally takes place in November or December. It is well attended by tourists, but even better attended by locals.
During the opening ceremonies（仪式）, after the official greetings from the government leaders, people who attend the festival begin to march smartly before the viewing stands, and white camels （骆驼）transport their riders across the sands. Horsemen from different nations display their beautiful clothes and their fine horsemanship. One following another, groups of musicians and dancers from all over the Sahara take their turn to show off their wonderful traditional culture. Groups of men in blue and yellow play horns and beat drums as they dance in different designs（传统文化）. On their knees in the sand, a group of women in long dark dresses dance with their hair: their long, dark, shiny hair is thrown back and forth in the wind to the rhythm of their dance.
The local and visiting Italian dogs are anxious to run after hares. The crowd is on its feet for the camel races. Camels and riders run far into the distance, and then return to the finish Line in front of the cheering people.
Towards the evening, there comes the grand finale of the opening day, an extremely exciting horserace. All the riders run very fast on horseback. Some riders hang off the side of their saddles. Some even ride upside down -- their legs and feet straight up in the air -- all at full speed. Others rush down the course together, men arm in arm, on different horses. On and on they went. So fast and so wonderful!
