1 . The research held the belief that the ability to use fins(鳍) to walk across the water affords the sharks a great advantage __________ the smaller animals they hunt. (用适当的词填空)

2 . In looking through your social media, there’s a good chance you’ve noticed pictures accompanied by texts. The pictures are likely made possible by a text-to-image program called DALL-E. For example, Twitter user posted a tweet with the text, “To be or not to be, rabbi holding avocado, marble sculpture.” Then a matching picture appears below.

The AI models come from Google’s Imagen software as well as OpenAI. a start-up backed by Microsoft. On its website, OpenAI calls DALL-E “a new Al system that can create realistic images and art from a description in natural language.” But most of what’s happening in this area is coming from a relatively small group of people sharing their pictures. That’s because Google and OpenAI have not made the technology broadly available to the public.

The text-to-picture services identify the most important parts of a user’s text and then guess the best way to picture those terms. There’s generally a text box, a button to start the generation process and an area below to display images. To indicate the source. Google and OpenAI add watermarks in the bottom right comer of images from DALL-E and Imagen.

Engineers trained the models on various collections of words and pictures from the web. OpenAI recognizes the potential for harm that could come from a model. To avoid the risk, employees removed violent content from training data, and there are filters（筛选）stopping DALL-E from producing images if users submit（提交）violent or illegal content.

Boris Dayma, a developer from Texas spelled out the problems in an explanation of their software. Despite the risks, Dhariwal, a research scientist at OpenAI, said it could open up creative opportunities for individuals and could help with commercial applications for dressing up websites. Results should continue to improve over time.

3 . Picture the scene: you’ve spent years working towards a very specific goal. You’ve put in countless hours of work and made many efforts along the way, but now that you’ve got there it doesn’t feel quite like you imagined. Instead of celebration, you feel emptiness, confusion and doubt.

Welcome to the anti-climax. The often-experienced but seldom-discussed downside of achieving life’s biggest milestones. Many of us work tirelessly towards our goals. We may spend our lives dreaming of the day we get married, publish our first hook or buy our first home. However, oftentimes, when we achieve these things it doesn’t feel quite as expected. In fact, the achievement of these goals feels a bit of a letdown.

So why do we often experience an anti-climax with big goals, even though we’re happy to achieve them? “An anti-climax can be an unexpected by-product of a milestone achievement. Usually, the more significant the milestone, the greater the anti-climax may be. The intensity（强度）of an anti-climax often relies on what we expect of this achievement.” says Rachel Vora. a psychotherapist（心理治疗师）.“The journey to achieving a milestone can he exciting and tiring in addition to giving us a sense of purpose and focus. Therefore, when this disappears overnight. we can often feel lost and confused, in spite of feeling proud of our achievement.

When this happens it can contribute to a mixture of emotions. We often falsely believe that we’ll feel completely different afterwards or that our feelings of low self-worth will disappear, but this is rarely the case. “Clients（客户）often present to me with an extremely great sense of ‘is this it?’ and ‘what now?’.” says Vora. “These feelings of confusion and disappointment, if let ignored, have the potential to cause clients to be in low spirits, or even worse.”

1. Why does the author mention the examples in paragraph 2?

A．To present a fact.	B．To prove a rule.
C．To explain a term.	D．To make a prediction.

2. What does Vora think is the leading cause of the anti-climax?

A．Low self-worth.	B．High expectations.

A．Amy felt empty before giving a speech.

B．Jack felt lost after his first novel came out.

C．Mary felt proud when she joined a ballet club.

D．Tom felt doubtful about taking further education.

4. What will the author probably talk about in the following text?

A．How to hold back feelings.

B．How to improve self-worth.

C．Hon to identify the anti-climax.

D．How to deal with the anti-climax.

4 . We were in for a whole new way of life when we moved to a horse farm in Winchester,Kentucky. One of the _______ parts of the move was getting to know the people in this small community.

5 . Cheating in sport is as old as sport itself. The athletes of ancient Greece used potions to strengthen themselves before a contest, and their modern counterparts have everything from anabolic steroids (类固醇) to growth hormones with which to_________their bodies. These days, however, such stimulants are_________, and those athletes must therefore face the challenges of anti-doping (反兴奋剂) agencies.

The agencies have had remarkable success. Testing for anabolic steroids was introduced in the 1970s, and the incidence of cheating seems to have_________dramatically as a result. The tests, however, are not entirely_________. And a study just published in the Journal of Clinical Endocrinology & Metabolism by Jenny Jakobsson Schulze and her colleagues at the Karolinska Institute in Sweden suggests that an individual’s genetic make-up could_________the tests in two different ways. One genotype, may allow athletes who use anabolic steroids to escape detection altogether. Another may actually be convicting (给……定罪) the innocent.

The test employed for testosterone (睾酮素) abuse usually relies on measuring the_________of two chemicals found in the urine (尿液): TG. and EG.. Any ratio above four of the former to the latter is considered_________and leads to more tests. However, the production of TG is controlled by a gene called UGT2B17. This gene comes in two varieties, one of which has a part missing and therefore does not work properly. A person may thus have none, one or two working copies of UGT2B17, since he inherits one copy from each parent. Dr. Schulze_________that different numbers of working copies would produce different test results. She therefore gave healthy male volunteers whose genes had been examined a single 360mg shot of testosterone — the standard dose for legal medical use — and checked their urine to see whether the shot could be_________.

The result was remarkable. Nearly half of the men who carried no functional copies of UGT2B17 would have gone undetected in the standard doping test.____________, 14% of those with two functional copies of the gene were over the detection threshold (门槛) before they had even received an injection. The researchers estimate this would give a ____________rate of 9% in a random population of young men.

Dr. Schulze also says there is substantial____________variation in UGT2B17 genotypes. Two-thirds of Asians have no functional copies of the gene which means they have a naturally____________ratio of TG to EG, compared with under a tenth of Caucasians (白种人) — something the anti-doping bodies may wish to take into account.

In the meantime, Dr. Schulz’s study does seem to offer innocents a way of____________themselves. Athletes who will travel to Paris for the Olympic games may be wise to travel armed not only with courage and the “spirit of Olympianism”, but also with a copy of their____________, just in case.

7 . The public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors has contributed to widespread mistrust and misunderstanding of scientists and their research. The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding.

However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for issues such as the genetic basis for a particular behavior or the use of animal models because in these areas, the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing scientific advances, more non-scientists will need to be able to analyze complex scientific information to make decisions that directly affect their quality of life.

Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient communication of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while sticking to scientific accuracy. Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material. As a result, the basic information conveyed is difficult to understand or obviously wrong.

Even though scientists play a part in conveying information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. I believe that, at least in part, the problem lies in places other than the interaction between scientists and members of the media. It exists because we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and most scientists do not receive formal training in science communication.

1. What does the example of climate change mainly serve to show?

A．Adequate government funding is vital to scientific research.

B．Government regulation helps the public understand science.

C．The public’s scientific knowledge can influence policy making.

D．There is widespread public mistrust and misunderstanding of scientific work.

2. Why is it important for scientists to build a good relationship with the media?

A．It helps scientists to build a better public image.

B．It helps them to effectively popularize scientific information.

C．It enables scientists to better apply their findings to public health.

D．It enables the public to develop a positive attitude toward science.

3. What is the problem with some pieces of science journalism?

A．They give inaccurate or complicated information.

B．They oversimplify people’s health problems.

C．They fail to mention the scientific advances.

D．They lack detailed information about scientific research.

4. According to the writer, what should scientists do to communicate to the public more effectively?

A．Interact more with the media.

B．Give training to science journalists.

C．Improve their communication skills.

D．Arouse the public’s interest in science.

9 . Whether you’re in the final research stages of a major paper, or on a Zoom (a calling app) call for work, a dropped WiFi connection at zero hour is something annoying.     1     One of the most common reasons it happens is that too many devices are connected.

    2     Now, with smartphones, iPads, smart TVs and so much more, it doesn’t take long for WiFi to hop aboard the struggle bus. Actually, even if a connected device isn’t actively sending or receiving data, it will still consume some of the available bandwidth. It means that if you have many devices connected, you can start to see slowdowns or drops in your WiFi connection.     3    

The first and easiest fix is to disconnect unused devices from your WiFi. The easiest way to do this is to simply change your WiFi password, which will kick everyone off. Then, you can allow only certain devices to rejoin.     4     It is workable to stop gaming or downloading a movie.

    5     First, run a speed test to check your current speed. (Google “speed test” to see a list of websites where you can do this.) You may have too many devices connected for the internet speed you’re paying for. If this is the case, contact your internet provider about upgrading to a higher speed. But you may want to try some of our other fixes first before spending the money.

A．What can you do about it?

B．Sometimes that’s all that’s required.

C．Finally, you may need to upgrade your connectivity.

D．People deal with this modern inconvenience all the time,

E．Cutting back on heavy WiFi use temporarily can also help.

F．In general, this is a very good solution to a dropped WiFi connection.

G．Back in the day, the average household had a computer or two to connect.
