5 . Comfort food makes a person feel good. Food high in sugar or fat tends to improve moods by stimulating the brain’s reward system. So it makes sense that many of us may turn to food for comfort in times of stress. There’s some fascinating research that examines food as a source of comfort. However, the most interesting thing about this research may be that foods are far less comforting than we tend to believe they are.

Traci Mann, a professor of psychology, and colleagues conducted a series of study with college students. The researchers examined how much comfort foods actually improve moods. They provided students with one of the three foods that they had indicated were their top, personal comfort foods. After producing a negative mood by having them watch movie clips designed to increase their sadness, anger and anxiety, the researchers offered the students their comfort food.

They had to assess (评估) how they felt before and after they were supposedly comforted by ice cream, pizza or whatever they had indicated they typically ate to feel better. All of the students completed the study on two separate occasions: once when they were able to eat their comfort food and once when they were able to eat another food they liked, but they wouldn’t call it a comfort food. The researchers found that comfort food did improve students’ moods — but only by a little bit and not more than the other food they liked.

In another study, comfort food was compared to no food at all, and students’ moods seemed to improve even when they didn’t eat anything — most likely just due to the passage of time.

The take-home message from the studies? While the comfort food may make the person feel better for the time being, it does little to address emotional problems. Of course, everyone can indulge (纵情) in a comfort food from time to time, but overall, aim for these instances to be the exception rather than the rule.

9 . People have understood that kindness is good for the person who receives help. For example, when we give food to a hungry person, he is blessed. However, scientists have recently begun to study the effect kindness has on the person giving it. What they have found is that doing good is good for the doer. Acts of kindness can improve health, help a person reach goals and even add years to a person's life.

The first study to show the connection between doing good and living a long life was a study on aging. Beginning in 1956, scientists studied a group of married mothers for 30 years. They thought the women with the most children would die first. But the number of children a woman had did not matter. Wealth did not matter. Education did not matter. What did matter was whether they volunteered. Women that volunteered had fewer diseases during their life.

Many other studies have found the same positive effects. Helping other people improves long-term health. The gains are the same for the men, women, old people and the young. Those who volunteered had fewer serious diseases than those who did not volunteer. This included diseases such as heart attack, cancer and stroke.

Scientists are researching many possible causes. One possible cause is an increase and antibodies (抗体), which help fight against disease. One study showed the body produces more antibodies after an act of kindness. This increase in antibodies can last nearly an hour after one act of kindness is finished.

Another one is an increase in chemical that fights the effects of stress from life. Scientists have found a link between being kind to people and an increase in the chemical oxytocin (催产素). Oxytocin is a chemical produced in the brain. It reduces many of the harmful chemicals the body produces under stress.

1. What did the study in paragraph 2 show?

A．Diseases age people fast.	B．Doing good is good for one’s health.
C．Women with more kids die earlier.	D．A long marriage leads to a long life.

2. What can we infer about antibodies from paragraph 4?

A．More antibodies may not be good.	B．They help people reduce pressure.
C．They increase with one’s kind acts.	D．The more antibodies, the more oxytocin.

3. How does the author develop the last two paragraphs?

A．By explaining the causes.	B．By making comparisons.
C．By introducing a method.	D．By describing a chemical.

4. What does the underlined word “it” probably refers to?

A．Oxytocin.

B．The brain.

C．Stress.

D．Helping others.

10 . Artificial intelligence(AI) models have long surpassed (超出) just creating text responses and images. Now, with only one sentence, OpenAI’s latest text-to-video model, Sora, can turn your words into video with good visual quality while completely following your content instructions.

Sora is said to be better than many other existing models with similar functions. The AI model can create videos at suitable aspect ratios (屏幕高宽比) for different devices. It also lets users quickly test out content in lower quality before making the high-quality version, which helps speed up output according to the user’s requests.

Apart from this, its ability to present videos in a realistic and smooth manner is surprising. Sora can create detailed scenes with several characters, specific types of motion, and accurate subject and background details. Beyond the user’s requests, it also understands how these elements exist in the real world. For example, reflections in the water change as a woman walks by.

However, the current model isn’t perfect. It may have trouble accurately showing how things move in a complicated scene and might not get how one action leads to another. For example, if someone eats part of a cookie in a Sora-made video, the cookie might not look like it’s been bitten into. The model might mix up directions and find it hard to describe events in the right order. One possible reason is that Sora learns each basic unit of a video, known as a spacetime patch (时空补丁), independently.

Sora is still in the testing stage of development. OpenAI is now inviting network security professionals to make random attacks on Sora’s system in order to test the model’s possible weaknesses and risks. Sora has also been open to some visual artists, designers and filmmakers. Their feedback will help OpenAI to improve the model to better serve creative professionals.

1. What is the main focus of paragraph 2 and 3?

A．Sora’s strengths.	B．Sora’s weaknesses.
C．Sora’s development.	D．Sora’s popularity.

2. Why does the author provide the example in paragraph 4?

A．To show Sora’s safety problems.	B．To show Sora’s existing weaknesses.
C．To show Sora’s perfect performance.	D．To explain the concept of a spacetime patch.

3. What can we know about Sora up to now?

A．It is being tested and improved.	B．It has enjoyed great popularity.
C．It has made random attacks.	D．It has been stopped.

4. What’s the best title for the text?

A．Sora: A perfect text-to-video AI model	B．Sora: A tool for chatting
C．Sora: Known as a spacetime patch	D．Sora: Lead the way in creating videos
