Open AI officially announced the launch of its     1     (late) text-to-video AI model, Sora, in February. The model outperforms (优于) others of its kind by creating diverse videos at suitable aspect ratios (屏幕高宽比) for different devices and social media. It can make smooth and realistic videos with     2     (detail) multi-character scenes and realistic movements. Imagine typing a     3     (describe) of a scene, like a snowy street in Tokyo with people and flying sakura (樱花) petals, and Sora turns it     4     a real video just from your words! How amazing!

Before Sora, making videos from text was tough and the results weren’t that great. But recently Sora     5     (improve) a lot. It understands your words really well and knows how things move and look in the real world. Sora works by “learning” from     6     large number of videos. It first breaks them down into pieces     7     then generates (生成) a new, better video from the pieces.     8     (current), Sora is still being tested and not for everyone to use. When     9     (create) videos, the model may mess up a character’s movement or show scenes     10     don’t follow the rules of physics. For example, one of its videos shows a whole cookie even after someone has taken a bite out of it.

5 . Yes, having a big name in science will help get your paper published, a new study confirms. Involving hundreds of researchers reviewing an economics paper, the study found that reviewers were more likely to recommend acceptance when the paper was associated with a famous author compared to a lesser-known one.

The Matthew effect, a term coined in 1968 to describe this prejudice, has been a topic of concern among scientists for years. However, previous efforts to document this prejudice had limitations such as small sample sizes or lack of randomization. To address these issues, a team from the University of Innsbruck conducted an extensive study.

The team sent emails to about 3,300 researchers, inviting them to review an economics paper for a real journal. The paper had two authors: Vernon Smith, a Nobel Prize winner, and Sabiou Inoua, one of Smith’s former Ph. D. students. The potential reviewers received one of three descriptions of the paper: one mentioning only Smith, another mentioning only Inoua, and a third with no author mentioned. Of the researchers who agreed to review the paper, Smith’s fame influenced their responses. When given only Smith’s name, 38.5% accepted the invitation to review, while the figures were 30.7% for those given no name and 28.5% for those given only Inoua’s name.

To further avoid prejudice, the team randomly assigned the 313 reviewers who initially received no author’s name to review one of three papers: one credited to Smith alone, another to Inoua alone,and a third with no authors listed. Reviewers rated the paper credited to Smith the highest, praising its inclusion of new information and data-supported conclusions. The version with no authors received recommendations for acceptance from 24% of reviewers, more than double the percentage for the version credited only to Inoua.

The team warned against evaluating identical work differently based on the author’s identity and suggested that double-blind reviews may reduce the prejudice. However, this approach may not be effective as reviewers can often identify authors through preprints or conference presentations.

Beside the sink, there was the flour bin and a bottle of buttermilk, the pale box of baking soda (发酵粉), a box of dried grapes, a box of salt, and a tin of caraway (葛缕子) seeds. On the small table beneath the window, a bowl and a spoon and the measuring cup. There was as well a narrow card on which she had written in her careful hand the recipe for soda bread.

It was time, my mother said, that I learned a few things about cooking. I stood in the kitchen doorway, all unwillingness. Why? I wanted to ask.

My mother tied an apron (围裙) around my waist. “All right,” she said. She node toward the table, the bowl and the spoon and the recipe card. I looked at her. The morning sunlight through the single window lit the down on her cheeks. It showed her brown eyes had some green in them, too. And that on either side of her tall forehead her dark hair was turning gray.

“Go ahead,” my mother said. “Get started.” And when she saw me hesitate, she put her hand on my shoulder and turned me toward the table and the bowl and the spoon. “Read the recipe over and then gather your ingredients,” she said slowly. “They’re all right here. I’ll watch and help.”

“Read it over,” my mother said. And I nodded, pretending to. The sun through the single window was bright in my eyes.

“Now gather what you need.” I picked up the flour bin and brought it to the table. I picked up the buttermilk and the dry grapes. I went back for the salt and the tin of caraway seeds and then stood before the bowl and the spoon and the measuring cup. Beyond the window, beyond the gray bars of the fire escape, the wash my mother had done this morning was waving on the line-sheets, my school blouses and my father’s shirts, which were hung upside down, their arms waving in a way that made me grow dizzy in sympathy.

10 . Some languages are rapid-fire and others more unhurried but there is no difference in the speed at which information is shared, according to the new research.

The world's 7000 or so languages differ greatly not only in their range of available phonemes-the units of sound that make up speech, but also in the pace at which these building blocks are thrown together in speech. But the new research into the information content in speech shows that languages allow their speakers to communicate about the same amount of information per second despite wide variations in the speed of speech.

To understand this better, researchers led by Christophe Coupé from the University of Lyon and Yoon Oh from the University of Canterbury studied recordings of 170 native adult speakers of 17 European and Asian languages. Each speaker read a set of standardized texts containing about 240, 000 syllables (音节). The researchers found that the fastest language hit 9.1syllables per second, and the slowest a mere 4. 3. But this was cancelled out by the amount of information, measured in bits, that each syllable contained. This varied significantly from 4. 8 bits per syllable for Basque to 8. 0 bits per syllable for Vietnamese.

The study found languages that pack a lot of information into sounds and syllables tend to be spoken more slowly, while those with a low information density (密度) are delivered more rapidly. While speech rat and information density fluctuate (波动) widely, the information rate-the speed at which information is delivered-stays consistently around 39. 15 bits per second.

The researchers say this appears to represent a optimal (最佳的) rat for giving and receiving information. Languages seem to stably inhabit an optimal range of information rates, away from the extremes that can still be available to individual speakers. Of course, not everybody speaks at the optimal information rate. We all know people who talk too quickly or slowly, and the new research may cast light on why we find listening to them hard work.

1. What has the new research found out?

A．Languages tend to convey information with similar efficiency.

B．Languages have nearly the same range of available phonemes

C．The number of languages has gradually decreased to about 7000.

D．The speed of speech is determined by the information content.

2. What is paragraph 3 mainly about?

A．A further explanation of the research methods.

B．A brief introduction of the research process.

C．Potential application of the research findings.

D．Supporting evidence for the research results.

3. What can we learn from the finding of Christophe’s study?

A．More words in speech convey more information

B．The information rate remains at a reasonable level.

C．The speech rate can affect the information density.

D．Languages with more syllables are delivered faster

4. What can be inferred about the optimal information rate?

A．It can lead to smooth communication.	B．It may result in the difficulty of listening
C．It stays the same for individual speakers.	D．It prevents speakers from going to extremes.
