A few cups of green tea each day may help prevent heart disease,Greek researchers said
on Wednesday.A study published in the European Journal of Cardiovascular (心血管的)
Prevention showed further evidence of the potential health benefits from tea already linked
to a reduced risk of a range of cancers and other conditions.
The study showed that green tea improves blood flow and the ability of arteries (动脉)
to relax,said Charalambos Vlachopoulos,an expert at the Athens Medical School in Greece
who worked on the study.
Other studies have shown that black tea also has benefits for cardiovascular health.
The Greek team said they believed green tea might be even better because it had higher
quantities of beneficial substances called flavonoids (类黄酮)-some of which are lost in the
oxidation (氧化) process that black tea undergoes.
Flavonoids are also found in cocoa,tomatoes and grapes."A couple of cups a day would
probably be good for people," Vlachopoulos said."This is the first study to show these
effects for green tea."
The researchers gave 14 healthy volunteers either green tea,coffee or hot water and then
measured the function of endothelial cells (内皮细胞).These cells help relax arteries and
ease blood flow."What is important is these effects are evident within 30 minutes,"
Vlachopoulos said.
The measurements taken 30,90 and 120 minutes following consumption showed an
almost immediate benefit among people who had drunk green tea,he said.While the researchers
looked only at a short-term effect,Vlachopoulos said the team's studies suggest the protection
is long-lasting.
"Green tea is consumed less in the Western world than black tea,but it could be more
beneficial,"he said.

Last year , my daughter was diagnosed with leukemia(白血病).
It is still hard to write that word. 16 is even harder to say it out loud, because it feels like that will make it more real. Although I wish I could either change the diagnosis 17
deny it altogether, this is what we’re facing. Every time we think about what her tiny body is doing to her, it 18 (break) our heart a little bit more. This is my worst nightmare.
But my husband and I are saying many thanks to God that her disease is the 19 (much)
common form of all the childhood blood cancers, which comes with an 85~90% cure rate. We believe that she is in that 90%, but we know there’s still a long road ahead 20 us.
21 (thank), she’s not in any pain, other than a little soreness from a recent procedure. And since she’s 4, she doesn’t quite understand 22 is happening at all. She is in good spirits, 23 helps us cope more than we realized it would. It also helps that she is in such 24 great hospital, specifically for children. They have done a great job, saving my daughter’s life and 25 (make) us go through the hard time as well.
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.
1.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
