1 . The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world’s most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.

| A．Scientific. | B．Credible. |
| C．Original. | D．Relevant. |
2 . This evidence, which is assumed to occur through a bio-behavioral mechanism, suggests that prevention strategies that target modification of psychological well-being-e. g. optimism-may be a potential avenue for AHA to reach its goal of improving Americans’ cardiovascular health by 20 percent before 2020.
What does the underlined word “avenue” in the last paragraph probably mean?
| A．Danger. | B．Approach. | C．Ability. | D．District. |
3 . Our own native language and culture are so much a part of us that we take them for granted. When we travel to another country, it’s as if we carry along with our passports. We view the new environment using our own culture as the standard, and although not purposely, our ways of thinking and acting often get in the way of our understanding other languages and cultures. The ability and willingness to change lenses(视角) when we look at a different culture is both the cure and prevention for such cultural blindness. Studying a new language provides us the opportunities to practise changing lenses when we also learn the context or the culture to which it belongs.
Q: The underlined word “it” in the last sentence refers to __________.
| A．the context | B．the culture |
| C．the language | D．the opportunity |
4 . And if you’ve gathered your friends around you to rebuild a happy family atmosphere(气氛), you may fear that saying no will bring back the kind of conflict you grew up with— or destroy the nice atmosphere you now enjoy.
Q: The underlined word “conflict” in the paragraph means .
| A．dependent life | B．fierce fight |
| C．bad manners | D．painful feeling |
5 . Oxygen is vital to life; it is needed by the body cells of all animals. It is also very useful in industry. The method Priestley used produces only small quantities. The large amounts needed for industry are produced in a different way. Air is put into containers under great pressure. This turns it into liquid and makes it very cold. It is then gradually warmed up and each substance evaporates at a different temperature. The boiling point of oxygen is -183°C. It is caught and stored in strong steel cylinders at a pressure of 136 atmospheres. The process is known as fractional distillation.
Q: Which word has the rough meaning of “vital”?
| A．Important. | B．Useful. | C．Helpful. | D．Interesting. |
6 . In the magnificent range of mountains of northern California, 42 radio telescopes point towards the stars, scanning for signs of life. The Search for Extraterrestrial Intelligence （SETI） Institute has been listening for a signal here since it was founded in 1984. Jill Tarter, its co — founder, says the programmed aim is not just to communicate with remote civilisations. It is also to remind human beings of its own modest, fragile （脆弱的）place in the universe. Thus, for the first time, SETI is cocking its ear towards Earth to look for a signal that can be sent into space to represent the species.
Felipe Perez Santiago, a Mexican musician and composer, has an idea of what might work.Since songs, like the human voices, are common to all languages and nations, he and Ms. Tarter have designed the “Earthling Project”-a call to people everywhere to upload extracts （精华）of song that he plans to melt into a collective human chorus. An initial composition will be launched into space this summer, recorded on a virtually indestructible disk. Future plans and dreams include an eventual landing on Mars.
Human music has been sent to the heavens in 1977. Distant beings can in theory already enjoy Peruvian panpipes, a Navajo chant, Bach, Beethoven and more. But no previous offering, and perhaps no composition undertaken anywhere, has tried to encompass the entire diversity of human song.
Mr. Santiago says he is thrilled about bringing together contributors from around the globe. Unlike other recordings sent into space, says Mr. Santiago, “Everyone's invited. You don't have to be one of the main composers of our history like Beethoven, just someone singing in their shower.” Download the “Earthling Project" app, sing up to three songs of 30 seconds each, and your voice will be sent into the sky.
1. Why does SETI look for a signal to be sent into space?| A．To stand for species on the earth. |
| B．To scan for other liveable planets. |
| C．To respond to the call of the universe. |
| D．To stress the importance of the earth. |
| A．It is a world music organization. |
| B．It intends to create a human chorus. |
| C．It tries to develop a universal language. |
| D．It aims to search for signals from space. |
| A．Include. | B．Appreciate. |
| C．Work out. | D．Relate to. |
| A．To inspire people to become composers. |
| B．To call on people to protect our planet. |
| C．To encourage people to explore space. |
| D．To invite people to join a programme. |
7 . JeffBezos has a rule at Amazon, or perhaps more appropriate a philosophy. If a team cannot be fed by two pizzas then that team is too large. The reasoning is quite straightforward and basic. More people means more communication, more bureaucracy, more chaos, and more of pretty much everything that slows things down, hence why large organizations are oftentimes considered as being so inefficient.
In 2013 Gallup released a report called “The State of The American Workplace", in which they found that smaller companies had more engaged employees. In fact,42% of employees working at companies of 10 or fewer were engaged at work versus only 30% of employees at large companies.
Most people are not familiar with the Ringelmann Effect which is the tendency for individual members to become less productive as the size of a group increases. This concept was named after Maximilien Ringelmann, a French professor of agricultural engineering who passed away in 1931.In one of his experiments he asked volunteers to perform a very simple task, to pull on a rope. He found that when only one person is pulling on the rope they give 100% of their effort; however, as more people are added the individual effort goes down.
This experiment was recreated in the 1970's by Alan Ingham who came up with the concept of “social loafing” which helps us understand why the individual effort decreases as the team size increases. So why does this happen? Because it becomes harder to extract the individual contributions and performance of each person.
Organizations should really think about what their team structures look like and create and follow similar “two pizza rules”. It's no coincidence that smaller organizations are oftentimes more nimble while large organizations look like they are stuck in the mud.

| A．What Makes a Team More Productive? |
