9．Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk．
Genetic engineering was used to introduce the"mothers'milk"genes into the animal before birth，according to the National Institute of Agribusiness Technology in Buenos Aires．
As an adult，the cloned cow"will produce milk that is similar to that of humans"，which will prove"a development of great importance for the nutrition of infants（婴儿）"，said the institute．"The cloned cow，named Rosita ISA，is the first in the world with two human genes that contain the proteins present in human milk，"said the statement．
In April，scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk．But the Argentine team said the Chinese only introduced one human gene，while their research involved two，meaning the milk will more closely resemble that of humans．
"Our goal was to raise the nutrition value of cows'milk by adding two human genes，which do good to the immune system of infants，"said Adrian Mutto，from the National University of San Martin which worked with the institute．
Cristina Kirchner，President of Argentina，said that the scientific institute made all Argentines proud．She also said that she had rejected the"honor"of having the cow named after her．"They came to tell me that the name is Cristina，but what woman would like to have a cow named after her？It appeared to me to be more proper to call it Rosita．"

8．In 1978，I was 18and was working as a nurse in a small town about 270km away from Sydney，Australia．I was looking forward to having five days off from duty．Unfortunately，the only one train a day back to my home in Sydney had already left．So I thought I'd hitch a ride （搭便车）．
I waited by the side of the highway for three hours but no one stopped for me．Finally，a man walked over and introduced himself as Gordon．He said that although he couldn't give me a lift，I should come back to his house for lunch．He noticed me standing for hours in the November heat and thought I must be hungry．I was doubtful as a young girl but he assured （使…放心）me I was safe，and he also offered to help me find a lift home afterwards．When we arrived at his house，he made us sandwiches．After lunch，he helped me find a lift home．
Twenty-five years later，in 2003，while I was driving to a nearby town one day，I saw an elderly man standing in the glaring heat，trying to hitch a ride．I thought it was another chance to repay someone for the favour I'd been given decades earlier．I pulled over and picked him up．I made him comfortable on the back seat and offered him some water．
After a few moments of small talk，the man said to me，"You haven't changed a bit，even your red hair is still the same．"
I couldn't remember where I'd met him．He then told me he was the man who had given me lunch and helped me find a lift all those years ago．It was Gordon．
