Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a non¬specific but stable change. For many people, the high¬tech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.
In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic genie is out of the bottle.
However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fast¬growing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?
The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.
How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.

The last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at home with her parents. All she’s ever wanted to do is to become an elementary school teacher. However, Hipp has racp(累计) $100,000 (about 0.67 million yuan) in student loan debt and isn’t able to earn enough through working as a part-time skating instructor and restaurant server to live anywhere other than home.
To some degree, multigenerational households have always been a part of American life. However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily.
The Pew Research Center recently reported that 2016 was a milestone in the evolving living arrangements of young adults in the US. Until 2016, the most common living arrangement for young adults was to be living in their own property as part of a couple. UBS Financial Services, a Swiss global financial services company, released a report that even suggests one reason for the growing number of young adults still living at home could be that their family doesn’t want them to leave. The report shows that 74 percent of millennials(千禧一代) get some kind of financial support from their parents after college. Millennials see their parents as peers, friends and mentors(导师). In return, their parents happily provide financial support well into adulthood, helping fund everything for them. Stuart Hoffman, chief economist for the PNC Financial Group in the US, said “Although job growth for millennials since 2014 has improved, that doesn’t necessarily mean that millennials are starting to fly the nest, he said. “They may like living at home and being able to save money.”
He added, “While it has held bacsehold formation and purchases on things, they are probably traveling more and eating out more. I don’t know if it represents a change in moral values, it’s much more common for adult children to live in their parent’s homes because it’s becoming part of the culture.”

We had a TV series in London. One of our fellow TV presenters seriously upset the camera crew when they arrived at his house. He was rude and unconcerned, treating them like lowly workers. Minutes later, when the camera was turned on, he became the perfectly smiling spiritual figure he was publicly known to be. But, as the crew told us later, he had already shown them that he didn't walk his talk.
In contrast, Ed was meeting with Jo, our TV producer, in a small London cafe. If you have ever been to London you'll know that in such cafe the tables are very close. Two well dressed African men sat down next to them, which effectively meant they were sharing the same table. Ed asked the two strangers where they were from and one said, "South Africa. " The man pulled out his business card—his name was Jacob Zuma who, at that time, was the President of the ANC but is now the President of South Africa.
Usually, if you sit next to someone in a big city cafe, you don't even make eye contact, let alone conversation. Jacob had never met Ed before so he could have been distant and polite, he certainly didn't have to talk, let alone maintain communication, which he did over the following few years. He even hugged him!
How we walr talk shows far more than just our public behavior. Rather, it highlights how we view the world and our place in it. Jacob Zuma showed us how he treats others—with the fairness, consideration and respect that he treats all beings. No matter who we are, whether a street cleaner or a president, we are all equal, here together as one human family.
