     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.

Before discussing different kinds of emotions, let us briefly talk about how researchers   1 bodily processes, actions and behavior, and how this relates to what we do in our daily lives when we observe emotions in  2  .
Bodily processes can be directly measured by   3  of a polygraph. (测谎器)When a polygraph is skillfully used to   4  how we react bodily with what we are   5 , it is called a "lie detector". Bodily processes can also be measured  6 . This is what we do when we observe someone blushing (脸红). However, we are not always  7  of what bodily processes respond to.
Measuring action   8  behavior is the other way researchers assess the emotions.    9 , one measure of fear of snakes is how  10 a person will go to the snake. Another procedure is to have a person  11  how afraid he is, or how he feels, in this way, researchers have 12  the so-called "fear thermometer" to assess a person’s fear.  13  our everyday living, we do very much the same thing. Only not too   14 . We react to what a person does, what he says, 15  he says it, and how he looks. Is he smiling? Is his voice trembling? We put all this  16  together to infer what a person is feeling.
  17 , we do not always act as we feel. Sometimes we do things that we don’t feel like doing.  18  we say we feel one way and then we act another. Actors, for example, successfully learn to "make believe" emotions, or learn to   19  them. Thus we   20  always tell what a person is feeling by what he says or by what he does.

The younger daughter of former New York Mayor Richard White has moved her wedding from New Year’s Eve to this Thursday so her mother, who has been fighting against cancer for 11 years, can take part in the ceremony, a family spokesman said on Wednesday, Oct, 12, 2013. Elizabeth Lally White, who turns 28 on Thursday, will marry Sam Peterson in Spiaggia, a restaurant on North Michigan Avenue. The reception also will be held at the restaurant, which had been previously scheduled to host the couple’s engagement party on Thursday.

Lally White’s mother, Maggie, 68, was reported to have caught breast cancer in 2002. She had an operation in her leg in April and she was hospitalized twice in the weeks following the procedure for treatment of flu-like symptoms that doctors said were not related to the cancer. Maggie, who has used a walker or a wheelchair during most public appearances in recent years, is well beyond the average survival time for someone with breast cancer.

“As the mayor himself has said, she had a pretty difficult summer.” said Jacquelyn Heard, who served Mayor White’s press secretary for years and followed him to the same international law firm that he joined after leaving office in May. “She was not able to get around the way that she normally would do. This year, she has had quite a few setbacks and they’ve been pretty well documented. Lally White decided to reschedule the wedding so that her mom can participate in the festivities (庆祝活动).” Heard said. Lally White is a doctoral candidate at De-Paul University and plans to work with autistic (孤独症) children, and Sam Peterson works in insurance, Heard said.

Richard and Maggie White married in 1972 and had three children in addition to Lally — Nora, Patrick and Kevin. But Kevin was born with a disease and died in 1981 at 33 months.

1.When was Elizabeth Lally White born?

A. In 1983.?????????? B. In 1987.?????????? C. In 1985.?????????? D. In 1984.

2.What can we infer from Paragraph 2?

A. Maggie, 68, is recovering now.

B. Maggie caught breast cancer in 2002.

C. The cancer caused some flu-like symptoms on Maggie.

D. Average breast cancer patients lived a life shorter than Maggie.

3.Why did Lally White reschedule her wedding?

A. She was afraid that her mother couldn’t participate her wedding on New Year’s Eve.

B. She was eager to work with autistic children after wedding.

C. Her family will move out of New York.

D. Her mother will accept operation because of her disease.

4.How many children did the former mayor and his wife give birth to?

A. 3.??????????????? B. 4.???????????????? C. 5.???????????????? D. 6.

5.What does the passage mainly talk about?

A. The political life of former Mayor.

B. The brave wife of former Mayor.

C. The wedding of former Mayor’s daughter.

D. The family life of former Mayor.

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species. That’s a move similar to what  Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen(氮). If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

60. The aim of “Noah’s Ark” project is to _______.

A. make efforts to clone the endangered pandas 

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

61. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.

A. available panda eggs                B. host animals

C. qualified researchers                D. enough money

62. The best title for the passage may be _______.

A. China’s Success in Pandas Cloning                       

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas  

D. China —the Native Place of Pandas Forever

63. From the passage we know that _______.

A. Kraemer and his team have succeeded in cloning a dog

B. scientists try to implant a panda’s egg into a rabbit

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand of species will probably die out in a century

Every pet owner loves his pet .There is no argument here.
But when we asked our readers whether they would clone their beloved animals , the responses were split(分裂) almost down the middle . Of the 228 readers who answered it ,108 would clone, 111 would not and nine weighed each side without offering an opinion .
Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and eventual (最终的)sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure (步骤)
Most of the readers who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope that clone could truly recreate a pet; many simply did not wish to go against the natural law of life and death.
Both sides expressed equal love for their animals. More of them owned “the best dog/cat in the world”. They thought of their pets as their “best friend” or “a member of the family”. They told moving stories of pets’ heroism, intelligence and selfless devotion.
No wonder the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
But would cloning reduce the blow? This question seems to be at the heart of this problem.
【小题1】
As far as the cloning of pets is concerned, a recent survey shows that, of all pet owners,     .

A.a lot more of them are for itB.a lot more of them are against it
C.very few of them are willing to tell their opinions
D.about half of them are for it and the other half against it
【小题2】
The expression “eventual sadness of owning a pet.” (in paragraph 3) refers to       .
A.the death of one’s pet
B.the final ownership of a pet
C.the troubles one has to deal with in keeping a pet
D.the dangers involved in the cloning of a pet
【小题3】
In spite of their differences on the problem of cloning, it seems that     .
A.all pet owners love their pets very much
B.all pet owners try to go against the natural law of life and death
C.people who support cloning love their pets more
D.people who dislike cloning love their pets more
【小题4】
From what Gary Kowalski says, we can know that he     .
A.has never thought about the problem of cloning
B.thinks it hard to accept the idea of cloning pets
C.is in favor of the idea of cloning pets
D.is all against the cloning of pets
