The Science magazine reported that scientists had successfully grown meat in their laboratory by November, 2018. The news aroused heated discussion among the public. Is the meat safe? Is it any different? Why do we have to grow meat in a lab? People have tons of questions about this. And the scientists said that the lab-grown meat is produced when cells from animals are grown under lab conditions. It isn't like plant-based meat substitutes (替代品) made from vegetable proteins (蛋白质), since cell-based meat is grown from actual animal cells. This means that it is an animal product, so not suitable for vegetarians.

Is cell-cultured meat the same as ordinary meat? The muscle fibers (纤维) produced in the lab are the same as those found in steak, said leading researchers in this technology at Maastricht University in The Netherlands. But they pointed out that to get the same nutrient. (营养物) content that is found in red meat, they need to make some changes to the procedure. Scientists say they are also looking into changing the type of fat in lab-grown meat, for example.

Some people have concerns with growing meat in the lab. Some say this method of meat production would result in less land and water use. Others argue that growing meat in the lab would influence the environment more negatively than our traditional way of raising cattle. It would take massive amounts of energy resources to produce meat in this way, they say.

Some groups have petitioned (请求) the US Food and Drug Administration (FDA) to better define the term “meat”. They want to know if we are buying the traditionally produced type or the cultured variety. Hopefully we will see some labeling guidelines on these products before they show up in grocery stores. And that may be a few years away. Regulatory issues and cost - the first lab-grown hamburger patty (肉饼) cost $330,000 (2274,900 yuan) - could delay the arrival of cultured meat.

What do you say when you pick up the phone?

You say “hello”, of course.

What do you say when someone introduces a friend, a relative, anybody at all?

You say “hello”.

“Hello” has been for a long time considered to be the standard English language greeting since English people began greeting. But is that true?

It may be the most spoken word on the planet and the English word that most people learn first. The word is so familiar to us that it's surprising how new it is: “hello” has only been in use for about the last 200 years of the 1000-year history of English.

The Oxford English Dictionary says the first published use of “hello” goes back only to 1827. But it wasn't mainly a greeting back then. People in the 1830s said “hello” to attract attention (“Hello, what do you think you're doing?”), or to express surprise (“Hello, what do we have here?”).

But the true breakthrough for this now-common word was when it was used in the service of brand-new technology: the telephone. According to the Oxford English Dictionary, it was Thomas Edison who put “hello” into common usage. He asked the people who used his phone to say “hello” when answering—which required people to address an unseen and unknown person. It was simpler and more efficient (高效的) than some other greetings used in the early days of the telephone, such as “Do I get you?” and “Are you there?” However, the actual inventor of the telephone, Alexander Graham Bell, thought that the better word was “ahoy”, which turns out to be much longer—at least 100 years longer—than “hello”. It too, was a greeting from the Dutch (荷兰语) “hoi” meaning “hello.” For his entire life, Bell insisted on answering the phone with “Ahoy.”

“Hello” obviously caught on, and spread along with the telephone. Had it not been for Edison, our greetings might be very different today. It could be possible that we are still greeting people with “Ahoy” when picking up the phone.

1.How long has “hello” been used in the 1000-year history of the English language?

2.What was the purpose of people saying “hello” in the 1830s?

3.Who put “hello” into common usage?
