If you bought some bread months ago but never ate it, how can you tell whether it is still safe to eat? The common way is to check the “use-by date”. If that date has already passed, you’re likely to throw the bread away. But is that really necessary?
According to a new report from the US Natural Resources Defense Council (NRDC), tons of food is wasted each year, largely because people don’t fully understand what “use-by dates” actually mean.
Food dating was introduced in the 1970s because consumers wanted more information about the things that they were eating. When they first showed up, use-by dates were only supposed to show freshness because producers wanted their products to be tasted in their best conditions.
But the truth is that these dates aren’t related to the risk of food illness, according to Times News. However, most customers misunderstood use-by dates and related them to the safety of the food, and they still largely do now. Eggs, for example, can still be eaten three to five weeks after selling even though the use-by date is much earlier. When their use-by dates pass, strawberry drinks may lose their red color and biscuits may lose their crunch (松脆), but they are not harmful.
This is why scientists are calling for a standard explanation to be printed following the use-by dates. “We want this to be clearly communicated so customers are not misunderstanding and causing a lot of waste,” said Dana Ganders, a staff scientist with the NRDC. But this will be a problem that is difficult to solve because people have believed it for so long. Another problem is that the quality levels of different foods change differently—some are still safe to eat long after their use-by date while others are not.
As a result, food industry officials are now thinking of changing the use-by date to a date indicating (指示) when food is most likely to go bad.

In old days, Chinese people have first name, last name(字).
This is Li Bai. His last name is Li. His first name is Bai, and his courtesy name is Taibai. When (当……的时候) people are at home, they call their first names. But when they go out, they call people’s courtesy names. Children don’t have courtesy names. Men can get their courtesy names when they are 20 years old. Women can get their courtesy names after getting married (结婚).
The courtesy name often(A) has something to do with the first name. Zhuge Liang’s first name is Liang. (B) It is “bright(明亮)”. His courtesy name is Kongming. It is “very bright”.

Artificial Intelligence (AI) tools have become extremely powerful, surprising even their creators. Now, some people say there should be a pause in AI work to make sure it doesn’t become dangerous, not everyone agrees.
Most people have probably read a book or seen a movie or show about an AI or robot that has become so smart that it can take over the world. The AI in stories like these is known as an AGI or Artificial General Intelligence. A true AGI would be intelligent in many different areas and would be able to learn on its own.
Now, there are no AGIs. Most experts believe it will be many years before an AGI could possibly be created. Most current Al tools are good at just one task, like answering questions, or identifying objects in photos. But scientists have worked to improve AI models, mainly by training the models on larger and larger collections of information. Those efforts are paving off. Extremely large models have surprised even their creators with what they can do.
The AI tools that’s got the most attention recently is ChatGPT, created by the company Open AI. ChatGPT is a Large Language Model (LLM). ChatGPT allows users to “chat” with a powerful LLM. When asked a question, ChatGPT answers quickly in perfect sentences. It makes up stories and games, writes essays, programs computers, and much more. ChatGPT appears to be extremely intelligent. But really, ChatGPT is simply guessing-based on its training information-which word is most likely to come next, over and over again.
Last month, OpenAI announced a more powerful model, called GPT-4. GPT-4 can create and explain jokes, and pass tests that are difficult for humans. GPT-4 was also trained on images, and can use them in powerful ways. For example, it can create a working website from a description and a rough drawing of the site.
The rapid progress of recent AI models worries some people. Last week, many computer experts released a letter calling for a six-month pause for any work on AI tools stronger than GPT4. Not all AI experts agreed with the letter. ChatGPT has caused so much excitement that many companies are likely to keep developing powerful AI tools. But the letter has sent a strong warning that many people-including leaders-will be thinking about carefully.
