1 . Americans spend billions on vitamins, multivitamins for their health, but a review of numerous studies concluded there is little to no evidence that some of those vitamins prevent heart disease, cancer or death.

The report, released by the U.S. Preventive Services Task Force last week, concluded that “recent evidence is not enough” to determine whether vitamins actually help or hurt your health, based on 84 studies, 52 of which were done since 2014. Vitamins examined included vitamins A, B, C, D and E, as well as other multivitamins.

“Our suggestion is neither for nor against taking vitamins, or combinations of those nutrients (营养物质). We just don’t have enough evidence,” said Dr. John Wong, a doctor in the Department of Medicine at Tufts Medical Center who was involved in the report.

While the finding is that vitamins don’t have any benefits to “healthy, non-pregnant (未怀孕) adults”, it doesn’t apply to “children, people who are pregnant or may become pregnant, or people who are hospitalized.”

The Task Force admitted it makes sense that people would take vitamins in hopes of health benefits, as some shortage may lead to illness. But experts agreed the best way to get good health and prevent cancer is a balanced diet and regular physical activity.

“The suggestion across all organizations about vitamins is to eat a balanced diet, and then the key tends to be on plenty of fruit and vegetables and less junk foods,” Wong said.

Wong added people should refer to their health doctors to determine if any vitamins are worth taking. He said this suggestion should also serve as a need to further research into proving the official benefits and risks for each vitamin.

1. Why can’t we say whether vitamins really benefit or harm health?

A．Because they really have no benefit.

B．Because many studies have proved it.

C．Because evidence is not enough at present.

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.

4. What is Dhariwal’s attitude to the future of DALL-E?

A．Positive.

B．Objective.

C．Uncertain.

D．Worried.

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.
C．Sense of purpose.	D．Unexpected achievements.

3. Which of the following is a case of the anti-climax?

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.

4 . Banff National Park is home to an amazing wildlife population. But the busy Trans Canada Highway that cuts through the park is a hazard to the lovely animals. To address the problem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”

There is some criticism (批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”

Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.

Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.

3. What are the critics worried about?

A．There are too many bridges and tunnels.	B．Many animals will not use the crossings.
C．More killings might happen at the crossings.	D．Illegal hunting might be encouraged in the park.

4. How does the author feel at the end of the visit?

7 . The Myers-Briggs Type Indicator (MBTI) was invented by Katharine Cook Briggs and her daughter Isabel Briggs Myers. It is a self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. The MBTI personality inventory (量表) sorts people into 16 type categories, each of which is represented by four-letter codes such as INFP and ESTJ. Every year, about 1.5 million people have enjoyed discovering their personality type by completing the MBTI. Many companies, as well as hundreds of universities, use it in hiring and training.

Nevertheless, the MBTI has received a noticeable criticism from the academic community. Some research suggests the MBTI is unreliable because the same person can get different results when retaking the test. Other studies have questioned the validity of the MBTI, which is the ability of the test to accurately link the “types” to outcomes in the real world -for example, how well people classified as a certain type will perform in a given job.

Merve Emre, a professor a Oxford University, points out that it would be more scientifically advisable to score the MBTI scales continuously to show people the degree to which they resemble the types. Even when the MBTI’s results don’t quite match your intuition (直觉) about yourself or are just wrong, they can still provide self-insight and insight into differences and similarities between people.

Scoring and interpreting the MBTI the way other personality inventories are scored and interpreted might be less fun than finding. All of the folklore (民间看法) about INFPs, ESTJs, etc. would have to be dismissed. But, in the end the MBTI is sufficiently reliable and valid enough to be useful in a number of real-world contexts.

3. What does Merve Emre think of the MBTI?

A．It is beyond criticism.	B．It is a more scientific test.
C．It is less fun than other tests.	D．It is useful for self-exploration.

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

A．How Can We Use the MBTI?	B．Why do We Criticise the MBTI?
C．Is the MBTI Totally Meaningless?	D．Is Scoring the MBTI Really Necessary?

10 . Europe is the perfect place for a holiday. Every corner of the continent is bursting with history, culture and sights. The countries are so very close to one another, and yet so completely different.

Sweden

Sweden is a brilliant destination for a campervan (露营车) holiday, with hundreds of well-appointed camping sites suitable for vehicles. Head north to Lapland in the Arctic Circle and you’ll find true wildernesses where you can truly get close to nature. Head here between June and mid-July and you’ll be able to take in the midnight sunshine. If you’re looking for great nightlife, head to Gothenburg, Stockholm or Malmo.

Germany

There are massive industrial cities, rolling plains, towering mountains, deep forests and long, sparkling rivers. It’s not just what’s to see that makes Germany so great, but the ease of seeing everything. All these wonderful locations are all linked by one of the world’s best road systems.

Scotland

Scotland has something for everyone: cities with rich nightlife, incredible scenery, wonderful lochs and medieval (中世纪的) castles. If you want to get away from it all, then the Highlands are one of the least populated areas in the whole of Europe. Hikers will love the Cairngorms – the largest national park in the UK.
