From Mr. Ward Hoffman.
Sir, I was halfway through Professor Raj Persaud's article “What's the tipping point"
(Financial Times Weekend, April 9-l0) when it occurred to me that what I was reading was not ironic(讽刺的). If Prof Persaud wants to know why Americans tip in restaurants, he need only ask the first American he meets in
Americans tip in restarts for one reason, and one reason only: we tip to supplement (补贴) the salary of restaurant workers. Quality of service does not enter into it, beyond the fact that one may tip a bit less for poor service, or a little more for good service.
Not tipping at all in a non-fast-food restaurant is not a choice. In the US, one used to tip about 15 per cent for dining in a family-style restaurant or in an up-market (高档的) restaurant. Here, in
After eating at an Italian restart in my city, I left a tip of 20 per cent on the non-tax part of our dinner bill. It was expected. There is nothing more complicated (复杂的) than that about Americas tipping in restaurants.
Ward Hoffman,

From Mr. Philip McBride Johnson.
Sir, I agree with most of Raj Persaud's opinion about the doubtful value of tipping, but with one exception(例外). Tips can be very useful when one is a repeat customer or diner.
It is only when the tipper is a stranger and likely to remain so that the system does not work to his or her advantage. But frequent a hotel or a restaurant, always tip a bit more, and the difference in service and treatment will ha easily felt.

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(物种). That’s a move similar to what a 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. 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.”
69. 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
70. 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
71. 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

UNICEF is appealing for more than one billion dollars in aid for women and children around the world. The United Nations Children's Fund has released its “Humanitarian Action Report” for two thousand ten. The report lists twenty – eight countries and territories with some of the world’s most pester affecting women and children.
Haiti was considered to be in crisis long before the earthquake in January. The deputy executive director of UNICEF, Hilde Johnson, says the quake has only made the need for aid more immediate. But she says children all over the world have the right to the same assistance as children everywhere else.
The "Humanitarian Action Report" discusses several issues that UNICEF says increasingly threaten the basic rights of women and children. It says climate change has caused droughts and food insecurity in many areas. High food prices and the global financial crisis of two thousand eight-two thousand nine have only added to poverty and malnutrition (营养不良). And armed conflict continues to threaten the lives of millions.
Hilde Johnson says children are always the most affected by conflicts and disasters. They face an increased risk of abuse, including sexual violence and other serious rights violations(侵犯).
UNICEF deals with about two hundred emergencies around the world every year. The greatest need last year was in sub-Saharan Africa. The report says drought, food insecurity and civil unrest affected about twenty-four million people.
Violence and displacements of people were especially bad in Sudan, Chad, the Democratic Republic of Congo and the Central African Republic.
In Asia, UNICEF expects its financial assistance needs to more than double this year. This is partly the result of adding Pakistan and the Philippines to the latest report. In Pakistan, it says, more than two million people have been forced from their homes by the conflict in the Swat Valley and other areas of the northwest. And in the Philippines, more than two hundred thousand people are still living in shelters after severe storms last year.
This year's UNICEF report talks about the value of public and private partnerships in helping children and families in emergencies.
And that's the VOA Special English Development Report, written by June Simms. For a link to the UNICEF report listing the twenty-eight countries and territories in crisis, go to www.unsv.com. I'm Steve Ember.
According to Hilde Johnson, the most easily affected peens suffering from conflicts and disasters are .
A．women B．children C．the old D．the disabled
From this passage we know that the most serious problems in Asia are .
A．earthquakes and malnutrition
B．displacemerds, and storms
C．seminal violence and other rights violations
D．droughts and food insecurity
By saying “… the quake has only made the need for aid more immediate.” Hilda Johnson probably intends to energy the idea that “ ”.
A．everything must have a beginning
B．grass never grows where the wide blows
C．cloudy herrings turn to clear evenings
D．it never rains but pours
Which of the following might serve as a suitable tickle for this passage?
A．Haiti was in crisis due to the earthquake in January.
B．Violence in the twenty – eight countries and territories
C．UNICEF Appeals for And for Women and Children
D．the vatic of public and private partnerships in helping
