2 . Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure? That the evidence was inconclusive, the science uncertain? That the anti-smoking lobby(游说) was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.
There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth’s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel’s report: “Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions.”
Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it’s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the time 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent person would take out an insurance policy now.
Fortunately, the White House is starting to pay attention. But it’s obvious that a majority of the president’s advisers still don’t take global warming seriously. Instead of a plan of action, they continue to press for more research — a classic case of “paralysis by analysis”.
To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won’t take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial supports for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

3 . It’s no secret that reading good news feels a lot better than reading bad news. Like, would you rather bite into a lemon, or sip on a fresh glass of lemonade?

4 . No one can fail to stand in awed admiration of the great discoveries of history — Newton’s laws of motion; Kepler’s principles of planetary movement, Einstein’s general theory of relativity. Equally awe-inspiring are artistic creations in painting, theatre, music and literature, which have also been brought about by discovery through personal efforts. What do these extraordinary achievements of well-known scientists and artists have to do with problem solving?
A great scientific discovery or a great work of art is surely the result of problem-solving activity. The solution to a problem, we are told, often comes to thinkers in a “flash of insight (顿悟)”, although they may have been turning the problem over in their minds for some time. As a particular form of problem solving, these creative acts are based on the broad knowledge gained in the past, whether this be of the “public” sort known to science, or of the “private” sort known to the artist.
Many creative thinkers state that they have completely devoted themselves to the subject matter of the problem, often over fairly long periods of time. Indeed, it would be strange if they had not done this. Nothing in such statements supports the idea that there is anything very different about the problem solving that leads to discoveries of the great contributions to the society. The act of discovery, even in the relatively predictable sense that it occurs in everyday learning, involves a “sudden insight” which changes the problem situation into a solution situation. As we have seen, everyday discovery also requires that the learner have the knowledge of the rules gained in the past, which is involved in the solution.

5 . The “Bystander Apathy Effect” was first studied by researchers in New York after neighbours ignored — and in some cases turned up the volume on their TVs — the cries of a woman as she was murdered (over a half-hour period). With regard to helping those in difficulty generally, they found that:
(1) women are helped more than men;
(2) men help more than women;
(3) attractive women are helped more than unattractive women.
Other factors relate to the number of people in the area, whether the person is thought to be in trouble through their own fault, and whether a person sees himself as being able to help.
According to Adrian Furnham, Professor of University College, London, there are three reasons why we tend to stand by doing nothing:
(1) “Shifting of responsibility” — the more people there are, the less likely help is to be given. Each person excuses himself by thinking someone else will help, so that the more “other people” there are, the greater the total shifting of responsibility.
(2) “Fear of making a mistake” — situations are often not clear. People think that those involved in an accident may know each other or it may be a joke, so a fear of embarrassment makes them keep themselves to themselves.
(3) “Fear of the consequences if attention is turned on you, and the person is violent.”
Laurie Taylor, Professor of Sociology at London University, says: “In the experiments I’ve seen on intervention, much depends on the neighborhood or setting. There is a silence on public transport which is hard to break. We are embarrassed to draw attention to something that is happening, while in a football match, people get involved, and a fight would easily follow.”
Psychotherapist Alan Dupuy identifies the importance of the individual: “The British as a whole have some difficulty intervening, but there are exceptional individuals in every group who are prepared to intervene, regardless of their own safety: These would be people with a strong moral code or religious ideals.”

| A．to explain why bystanders behave as they do |
| B．to urge people to stand out when in need |
| C．to criticize the selfishness of bystanders |
| D．to analyze the weakness of human nature |
6 . In recent years, China has witnessed the growth of luxury (奢侈品) brands. In this market, Chinese consumers are now the largest spenders. It’s clear that a new generation of young, materialistic people is increasingly relying on luxury brands to improve its self-image. I am a fashionist too, at least in spirit—I love to look at clothes and shoes. But I don’t understand why people spend lots of money on designer labels. When a young woman buys a handbag that costs two months of her salary, that’s a scary thing.
What’s interesting is that scientists have found that having luxury things doesn’t lead to happiness. Study after study has shown that although we want material things, when we get them we don’t suddenly become “happy” people. In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, has shown that individuals who spend money on travel and similar experiences get more pleasure than those who invest it in material things. That’s because experiences are more easily combined with a person’s identity. If I travel to Yunnan, that adventure affects how I think in the future. My memories become a part of me.
Moreover, as Van Boven has observed, young people who pursue happiness through “things” are liked less by their peers. People prefer those who pursue happiness through experiences.
It’s natural to want to express yourself through your appearance. So my advice is: create a look that isn’t tied to a designer label. Convey your own message. Take some lessons from the late Apple co-founder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don’t have to break the bank to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.

8 . If you live on this planet, there’s a decent chance you’ve seen the classic Star TrekEpisode, in which captain Kirk and several members find themselves in what appears to be another universe.
These days, it seems the idea of the multiverse—many worlds—is having its Hollywood moment. Its appeal as a storytelling device is obvious—characters explore a multi-world with varying degrees of similarity to our own, as well as different versions of themselves. Hence, it has been fully established in mainstream pop culture.
While Hollywood can’t seem to get enough of the multiverse, it remains deeply controversial (有争议的) among scientists. Advocates on the two sides show no mercy toward each other in their books, on their blogs. But physicists didn’t pull the idea out of thin air—rather, several distinct lines of reasoning seem to point to the multiverse’s existence. However, critics warn that making the multiverse legal could make it harder for the public to distinguish speculative (推测性的) theories from established fact, making it more difficult to keep pseudo-science (伪科学) at bay. Giving credit to such speculation risks “turning fundamental physics into pseudo-science”.
The multiverse controversy is rooted in the idea of test ability. If we can’t interact with these other universes, or detect them in any way, some experts insist that reduces them to mere philosophical speculation. But Carroll, an advocate for “many worlds”, argues that mathematics is the language describing our physical theories. Since Schrdinger’s equation (方程), on which Quanturr (量子) mechanic rests, predicts the existence of many worlds, so be it.
Could a more expansive view of the universe itself be the next breakthrough? As Siegfried puts it: “Every time in the past that we’ve thought, ‘We’ve got it; this is what the whole universe is’—the people who’ve said, ‘Maybe there’s more than one of those’ have always turned out to be right.”
1. Why is Hollywood so occupied with the multiverse?| A．It makes for engaging plots. |
| B．It is a much-talked-about topic. |

| A．it can be detected somehow |
| B．it can be reasoned logically |
| C．it can be interpreted philosophically |
| D．it can be predicted by mathematics equation |
| A．Doubtful. | B．Dismissive. | C．Unclear. | D．Approving. |
9 . Genetic testing companies have a long history of creative attempts to reach the mainstream. An early example was the sequencing of rock star Ozzy Osbourne’s genes in 2010, with accompanying guess about how they might have influenced his drug habits.
Lately, such projects have taken on a new, highly commercialized tendency. In 2017, we got the “Marmite (马麦酱) gene project,” run by London-based genetic testing start-up DNAfit. It claims to show that love or hate for Marmite was in our genes. The project turned into a full-blown marketing campaign, and even sold Marmite-branded DNA testing tools.
DNAfit is now working with Mercedes-Benz to find out whether specific genetic traits are associated with business wisdom. AncestryDNA, the world’s largest consumer genetic testing company, last year teamed up with Spotify to promote “music tailored to your DNA.” Just a few weeks ago, 23andMe, the second largest, announced a partnership with Airbnb to provide genetically tailored travel experiences, also inspired by ancestral DNA.
I have skin in this game. I run a genetic-testing start-up that connects people who want their genome sequenced with researchers who want data to improve their understanding of genetic disease. I believe that broadening access to DNA testing can be a powerful force for good, providing safer, more effective medicines and giving people more power over their healthcare. But these campaigns risk discrediting the industry, by giving a misleading impression of what genetics can and can't say and its role in determining behaviours and personal preferences.
Take the Marmite study. It covered 261 people — tiny, by the standards of the field. It was published not in a journal, but online on bioRxiv, a server where scientists typically put results before peer-review. Shortly after, researchers looked at the genetic data of more than 500 times as many people in the UK Biobank and found no such correlation. A large peer-reviewed study in 2013 found no significant link between genes and business common sense.
We need to inform the public about what this is all about: that is, the gathering of large amounts of genetic data. We need better regulation to ensure that consumers are clear that this may happen with this sensitive personal information. A checkbox on a 20-page web document full of legal terms should not be enough.
Scientists too, need to start asking hard questions about whether the information they are using has been sourced ethically. DNA testing has a great future, but we can't build this future with data acquired by any means.

10 . In the rich countries of the West, the electric vehicle revolution is well underway. Climate-conscious consumers drive Teslas or Polestars for reasons of morality and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.
Yet a glance under the hood (引擎盖) of these vehicles reveals a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries, containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leak into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable but deadly business.
Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an extraordinary scale. The numerous ways lead enters air, water, soil, and homes across the developing world — and the enormous damage it does to human health, wealth, and welfare — causes one of the biggest environmental crises in the world yet receives little attention.
The World Bank estimates that lead kills 5. 5 million people per year, which would make it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is extraordinary, as is its contribution to global inequality — our research on the cognitive effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.
But unlike many challenges faced by developing countries, lead poisoning is a problem that is fixable with some attention and a relatively modest financial investment. Better monitoring, research, and rules can help protect children all over the world from the dreadful effects of lead poisoning and reduce the massive global costs it brings.
