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.

阅读理解.     Since its opening,camp teachers at New Jersey"s Liberty Lake Day Camp disinfect
(给……消毒) door knobs,take the temperatures of children as they arrive and remind
the campers not to share canned Coke.
     Many of the 12,000-plus summer camps in the United States are making greater efforts
to guard against the spread of the new A/H1N1 flu.
     Many parents are debating whether they should stop their kids from enjoying the summer
camp because of the new flu.Jing Zhang of New York said she decided to keep her
5-year-old daughter at a local day-care center."Why would I want to spend a fortune on
the summer camp when the risk is the same?" she asked.
     Dr.Daniel Rauch,said the risk of catching A/H1N1 flu is only greater in close or group
settings,for instance,when kids sleep near each other in beds,tents or cabins.Unless children
already have potential illness or immunodeficiencies (免疫缺陷),going to summer camps
does not necessarily have a greater risk of catching A/H1N1 flu than going to public spaces
such as playgrounds and shopping centers,he added.
     Some camp administrators said they would send any sick child home immediately or
separate them in a clinic and let them play board games while they are being observed.
"We try to create a temporary camping center in the summer and we are very vigilant
about it," said Andy Pritikin,director of Liberty Lake Day Camp in Mansfield,who sent a
child with fever home last week,with full credit to come back later in the summer.
     "Parents should know whether camp nurses are available.And if there"s only a bottle
of medicine and a bed in the back room,and it takes three and a half hours to get to the
nearest hospital,parents need to know that," said Sean Nienow,director of the National
Camp Association.
1．To protect campers from A/H1N1 flu,the organizers have taken the following
measures EXCEPT________.A．taking campers" temperatures on their arrival
B．building temporary clinics near camping places
C．separating sick campers or sending them home soon
D．reminding campers of some matters they need to pay attention to2．According to Dr.Daniel Rauch,________.A．taking children to public places and sending them to camps are both safe
B．parents should not let their children go camping or take them to public places
C．going to summer camps doesn"t mean an increasing risk of catching A/H1N1 flu
D．sending children to camps is more dangerous than taking them to public places3．The "vigilant" in the fifth paragraph refers to"________"．A．cautious

D．confident4．Which of the following can be inferred from the passage?_____A．Experts encourage parents to send their kids to camps.
B．Parents are very worried about the spread of A/H1N1 flu.
C．A/H1N1 flu has spread widely among young campers in the US.
D．Children who have potential illnesses are not allowed to go camping.5．What can we learn from what Sean Nienow says in the last paragraph?_____A．The medical conditions are poor at the camp.

     Nowadays, most of us live a busy life. What do you do to keep yourself relaxed?
Besides spending time with family, having a glass of wine with friends or reading a book,
how about a hobby?
     Personally, I"m a collector. I like blue and white pieces the best---blue and white
anything﹗Plates,jars,vases, cups, bowls---I love them all. Collecting items is like
something you can"t get enough of. You get one, and you want to have more.
     I find collecting to be a fun and inspirational hobby. In many ways, it"s like a puzzle
I"m never tired of solving. I look high and low for new pieces to add to my collection. I
can often be found visiting Marshell"s, looking over their inexpensive offerings. In fact, I
found one of my favorite pieces there.
     I"ve mixed inexpensive pieces from Marshell"s with more expensive finds. A lot of times,
it"s the piece I"m not looking for that falls into my lap; I find a way to make it part of my
blue and white family. What I love about my collection is that when I get inspired, I can
move them around the house, mix and match and make things look fresh and new.
     Ever since I was a little girl, blue has been my favorite color. I think I got it from my
aunt in Mexico. Some of my earliest memories are visiting her in Mexico and sitting on a
chair in her kitchen, which had blue and white tiles(瓷砖)from the floor to the ceiling. I
would spend countless hours admiring all the beautiful blue and white plates and shiny blue
tiles around her kitchen. Once I had a home, I began to build my own blue and white
collection.

     Your body, which has close relation(关系) with the food you eat, is the most important thing you
own. So it needs proper treatment(对待) and proper nourishment(营养).
     The old saying “An apple a day keeps the doctor away” is not silly as some people think. The body needs fruit and vegetables because they contain vitamin C (维生素C). Many people take extra(额外的) vitamins in the form of pills(药丸), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins. So why waste money on them?
     In the modern western world many people are too busy to care about eating  properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illness caused or made worse by bad eating habits is frightening.1. The old saying in the passage tells us that_______.A. the apple is the best among all kinds of fruits.
B. apple can take the place of doctors.
C. eating apples regularly (有规律的) does lots of good to our health.

______.A. only eat an apple a day.
B. eat properly.
C. take as many vitamins pills as possible.

阅读理解。     English families face being limited to 80 bags of rubbish a year. Households throwing away
more waste will have to take it to the tip (垃圾站) or buy a limited number of extra bags.
     Doretta Cocks, protester of the Campaign for Weekly Waste Collections, said, "They must
think we are fools. How can they claim to be concerned for the environment when they tell people
to drive to the local tip? And what do you do if you don"t have a car? Walk?"
     The plan ignores the voice from ministers to end such heavy-handedness (笨拙).
     It is to be carried out by the Tory-led council (市政厅) in Wokingham, Berkshire, and is
already in operation in Brozbourne in Hertfordshire.
     Many of the 180 councils that still offer unlimited weekly rubbish collections are watching the
trial.
    Wokingham officials have told residents that 75-litre bags will be given to each household and
anything not left in them will not be collected.
    "Every household will receive 80 bags every year," it said. "You can buy extra bags in rolls of
ten but this will not be encouraged."
    Families of five will get 100 rubbish bags a year and households of six or more will get 120.
    Residents will have a weekly recycling collection limited to cans, paper and cards, plastic bottles
and so on.
    Plastic packaging and glass including bottles must either go with the general waste or be taken to
recycling points. Green waste pick-ups cost an extra ￡60 a year.
    The council has told residents it will save ￡922,000 a year under the new system. There will be
no local consultation (商讨) before it is introduced next April.1. What" Doretta Cock"s attitude towards the new plan?A. Satisfied.
B. Curious.
C. Angry.
D. Interested.2. What does the underlined word "this" refer to in the seventh paragraph?
