1 . Each food product in the United States must show a “best before” date on its container. The goal is to tell the buyer when the food will be at its freshest. Most people believe it is unsafe to use the food product after that date. But some observers say “best before” labels have nothing to do with safety. They worry that the information will lead consumers to throw away food good to eat.

Some food sellers in Britain recently removed “best before” labels from prepackaged fruit and vegetables. The European Union may soon announce changes to its labeling laws. It may even end the requirement to include a date.In the US, there is no similar effort. Some big food store owners and food companies are pushing for the US Congress to pass new laws on the subject.

Studies have found as much as 35% of available food goes uneaten in the United States.That adds up to a lot of wasted energy. It also means more greenhouse gases coming from landfills. 7% of US food waste comes from people’s misunderstanding of “best before” labels. That percentage is equal to about 3. 6 million tons each year.

Richard Lipsit owns a store called Grocery Outlet in Pleasanton, California. He said we can safely eat canned goods and many other packaged foods for years after their “best before”date. People should look for changes in color, thickness, or feel to learn if foods are all right to eat. “Our bodies are very well equipped to recognize the signs of decay,” Lipsit said. “We’ve lost trust in those senses and we’ve replaced it with trust in these dates.”

If new laws are approved in Congress, food could be donated to food rescue organizations even after its quality date has passed. Food rescue is making efforts to find uses for outdated food. Currently, at least 20 states ban the sale or donation of food after its quality date has passed.

2 . Nowadays, the world is slowly becoming a high-tech society and we are now surrounded by technology. Facebook and Twitter are innovative tools; text messaging is still a somewhat existing phenomenon and even e-mail is only a flashing spot on the screen when compared with our long history of snail mail. Now we adopt these tools to the point of essentialness, and only rarely consider how we are more fundamentally affected by them.

Social media, texting and e-mail all make it much easier to communicate, gather and pass information, but they also present some dangers. By removing any real human engagement, they enable us to develop our abnormal self-love without the risk of disapproval or criticism. To use a theatrical metaphor (隐喻), these new forms of communication provide a stage on which we can each create our own characters, hidden behind a fourth wall of tweets, status updates and texts. This unreal state of unconcern can become addictive as we separate ourselves a safe distance from the cruelty of our fleshly lives, where we are imperfect, powerless and insignificant. In essence, we have been provided not only the means to be more free, but also to become new, to create and project a more perfect self to the world. As we become more reliant on these tools, they become more a part of our daily routine, and so we become more restricted in this fantasy.

So it is that we live in a cold era, where names and faces represent two different levels of closeness, where working relationships occur only through the magic of email and where love can start or end by text message. An environment such as this reduces interpersonal relationships to mere digital exchanges.

Would a celebrity have been so daring to do something dishonorable if he had had to do it in person? Doubtful. It seems he might have been lost in a fantasy world that ultimately convinced himself into believing the digital self could obey different rules and regulations, as if he could continually push the limits of what’s acceptable without facing the consequences of “real life.”

1. What can we know about new communication tools?

A．Destroying our life totally.	B．Posing more dangers than good.
C．Helping us to hide our faults.	D．Replacing traditional letters.

2. What is the potential threat caused by the novel communication tools?

A．Sheltering us from virtual life.	B．Removing face-to-face interaction.
C．Leading to false mental perception.	D．Making us rely more on hi-tech media.

3. What can be inferred from the last two paragraphs?

A．Technologies have changed our relationships.

B．The digital world is a recipe for pushing limits.

C．Love can be better conveyed by text message.

D．The digital self need not take responsibility.

4. Which of the following is a suitable title for the text?

A．Addiction to the Virtual World	B．Cost of Falling into Digital Life
C．Interpersonal Skills on the Net	D．The Future of Social Media

3 . It has become easy for students to find and copy published material. But copying another person’s writing without giving them credit can get students and other scholars into big trouble.     1    

American copyright law protects original works of authorship including books, movies, music, images and artworks.     2     The owner can sell a copyright or permit others to use it because it is property and property ownership is protected by law in the U. S.

The idea is that copyright helps society. If people can gain from their own creations, which are called their intellectual property (知识产权), then more people will want to create original works. The law, however, permits the unlicensed use of copyrighted works under what is called fair use. Fair use can include criticism, comment, news reporting, education and research.     3     In education, students can include small parts of copyrighted work in their writing and research. But they must provide credit to the original creators through a citation which gives details about the source.

Just as it is easy to copy, it is also easy for professors to know if a student has plagiarized. First, there are computer programs and artificial intelligence, tools that compare students’ papers to large databases of published writing.     4     Second, if English is not a student’s first language, a professor might recognize a change in wording and writing style. This could bring more attention to the student’s paper.

    5     Professors could simply warn a student not to do it again, lower their grade, or they might fail the student in that class. In more extreme cases, a student may be temporarily banned or expelled from school.

A．This behavior is called plagiarism.

B．However, there are some limitations.

C．Plagiarism is punished in different ways.

D．Students must follow university policies on academic behavior.

E．They can identify whether students have copied published writing.

F．For example, it can automatically create citation s and combine them into a list.

G．The protection extends to computer software and the design of buildings and structures.

7 . The first wave of concerns over artificial intelligence(AI)in 2023 appeared soon after New Year’s Day when classrooms reopened and schools from Seattle to Paris started blocking ChatGPT, a powerful software based on AI large language models, because teenagers were using it to do their homework.

The AI large language models behind such products as ChatGPT work by repeatedly guessing the next word in a sentence after having “learned” the rules from a huge amount of/human-written works. Although they often get facts wrong, their answers appear so natural that Keven, their inventors begin to worry about their possible use for spreading false information.

People became more worried when various AI products started to create not just texts but novel images, music and human voices, which threatened the livelihoods of anyone who writes, draws or sings for a living. It led to strikes by Hollywood writers and actors and legal challenges from artists and bestselling authors. Some of the most respected scientists even warned that the technology’s unchecked progress was possibly threatening human existence. “In the longer term, they might manage our attention,” pioneering AI scientist Fei Fei Lisaid. “They would tell us which video to watch, which book to read or whose communication to respond as AI technology’s abilities improve rapidly. They could be a very good assistant, but also with really big risks.”

Li hoped that 2023 is going to be a year for people to think about what Al is, how to use it and what the effects are — all the good, the bad and the ugly.

“It’s easy to forget that they are not the first wave of AI products. Computer vision techniques developed by Li and other scientists have helped sort through a huge database of photos to recognize objects and individual faces and guide self-driving cars. Speech recognition advances have made voice assistants like Siri and Alexa a normal thing in many people’s lives,” said Tom Gruber, co-founder of Siri Inc.

A．ChatGPT often got facts wrong in the class.

B．Students spent too much time on the software.

2. What are the second and third paragraphs mainly about?

A．AI’s training costs.	B．ATs amazing abilities.

3. What would Tom Gruber most probably suggest people do?

A．Think carefully about AI’s impact.	B．Welcome AI technology
C．Do use ChatGPT more carefully.	D．Upgrade ChatGPT in time.

4. Where is the text most probably taken from?

A．A news report.	B．A guide book to a software.

Dinah (China)

I enjoy the happy atmosphere of both Chinese and Western festivals. As long as it is meaningful for me, I will celebrate it with my boyfriend, and my parents! I like Western festivals and often celebrate them without even knowing the origins of them. Why? Because what I really appreciate is just the happy atmosphere.

SharkMinnow (Canada)

Western Festivals are more like parties or games for some Chinese. Also, spending money = good for economy. Most Chinese don’t take Western festivals as seriously as their own. It’s like a game or party in my eyes. A way to blow off steam and have fun (and spend money).

Travis (UK)

As an Englishman teaching here in China for two years, my friends have got used to, and enjoy when I celebrate my festivals. My school also likes it as well, although this year they asked me not to scare the teachers so much on Halloween. My Chinese friends enjoy taking part in my festivals, as they also learn more about my culture, and the history that goes with it…

Leesinchina (US)

Cherish your own festivals. It would be a pity if the Chinese accepted these Western days — first, because they have absolutely nothing to do with traditional Chinese culture.

Stick to your own festivals — they actually mean something to you — rather than following western customs for no good reason.

10 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Gather together a couple of good friends and take a leisurely walk through the streets—this is what many youngsters in China enjoy doing when they pay a visit     1     a new city. To them, Citywalk means “wandering around the city” on foot. Participants can follow a special urban route, exploring old     2     (building) or enjoying real local snacks.

The origins of Citywalk can be traced (追溯) back to London, England. Strictly speaking, this form of urban tourism     3     (be) not as casual and aimless as it may appear. In the beginning, Citywalk referred to tours where participants followed a     4     (plan) route under the guidance of tour conductors, exploring deep into the city’s history, culture, landscapes     5     other aspects. Gradually, the concept of Citywalk,     6     focuses on the quiet appreciation of urban lifestyle and cultural atmosphere, has gained popularity worldwide.

Up to now, the Citywalk trend     7     (spread) from first-tier cities like Beijing and Shanghai to second-tier and third-tier cities, encouraging more participants and event organizers to get involved. Some organizers invite folk culture researchers and enthusiasts (爱好者)     8     (act) as tour guides.

In short, Citywalk not only offers     9     way for young people to interact with a city but also provides them with a new social scene, where people wit the same interests and ideas can     10     (easy) make friends.
