1 . In May 1987 the Golden Gate Bridge had a 50th birthday party. The bridge was closed to motor traffic so people could enjoy a walk across it. Organizers expected perhaps 50,000 people to show up. Instead, as many as 800, 000 crowded the roads to the bridge. By the time 250,000 were on the bridge, engineers noticed something terrible：the roadway was flattening under what turned out to be the heaviest load it had ever been asked to carry. Worse, it was beginning to sway（晃动）. The authorities closed access to the bridge and tens of thousands of people made their way back to land. A disaster was avoided.
The story is one of scores in To Forgive Design：Understanding Failure, a book that is at once a love letter to engineering and a paean（赞歌）to its breakdowns. Its author, Dr. Henry Petroski, has long been writing about disasters. In this book, he includes the loss of the space shuttles（航天飞机）Challenger and Columbia, and the sinking of the Titanic.
Though he acknowledges that engineering works can fail because the person who thought them up or engineered them simply got things wrong, in this book Dr. Petroski widens his view to consider the larger context in which such failures occur. Sometimes devices fail because a good design is constructed with low quality materials incompetently applied. Or perhaps a design works so well it is adopted elsewhere again and again, with seemingly harmless improvements, until, suddenly, it does not work at all anymore.
Readers will encounter not only stories they have heard before, but some new stories and a moving discussion of the responsibility of the engineer to the public and the ways young engineers can be helped to grasp them.
"Success is success but that is all that it is," Dr. Petroski writes. It is failure that brings improvement.

4 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.
As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.
According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.
The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.
The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.
By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

5 . As the concept of emotional intelligence (EI) has gone global, we’ve watched professionals fail as they try to improve their emotional intelligence because they either don’t know where to focus their efforts or they haven’t understood how to improve these skills on a practical level. In our work consulting with companies and coaching leaders, we have found that if you’re looking to develop particular EI strengths, it helps to consider areas for improvement others have identified along with the goals you want to achieve and then to actively build habits in those areas rather than simply relying on understanding them conceptually.
The first step is to get a sense of how your self-perception (how you see yourself) differs from your reputation (how others see you). This is especially true for the development of EI because we can be blind to how we express and read the emotional components of our interactions. For example, most of us think that we’re good listeners, but very often that’s really not the case. Without this external reality check, it will be difficult for you to identify the ways that your actions affect your performance. Getting teed back from others can also provide proof of the necessity of shifting our behavior and motivation to do so.
To give you the best sense of where the differences lie between your self-perception and reputation, you should use a 360-degree feedback assessment that takes into account the multiple aspects of EI. The key is to find one to give you feedback, which is focused on development and not on performance assessment. And that can give you a detailed understanding of how other people’s assessments of you differ from your own assessments.
Secondly, when you get your feedback from an assessment, let that inform what you want to improve. But also consider what your goals are. When it comes to cultivating strengths in emotional intelligence, you’re at a huge disadvantage if you’re only interested because others say you should be. Your emotional intelligence is so tied up in your sense of self that being intrinsically (内在的) motivated to make the effort matters more when changing longstanding habits than it does when simply learning a skill.
That means the areas that you choose to actively work on should lie at the intersection of the feedback you’ve gotten and the areas that are most important to your own aspirations (抱负). Understanding the influences of your current EI habits relative to your goals will keep you going over a long period at time as you do the work or strengthening your emotional intelligence.
1. What do we know from the first paragraph?| A．EI can be better improved with others’ help. |
| B．Leaders are badly in need of improving their EI. |
| C．EI plays a key role in professional development. |
| D．Professionals fail to understand the concepts of EI. |

6 . Do you ever hear a friend speak on a topic with the belief that “everyone”thinks the same way? Do you often find yourself surrounded in a social media feed that is completely tailored to you and your beliefs, reading along without the immediate realization?
A social media echo chamber (回声壁) is when one experiences a tailored media experience that leave out opposing viewpoints and differing voices. Social media sites like Facebook, Twitter, and YouTube connect groups of like-minded users together based on shared content preferences. As a result, people see and take in information according to our preexisting beliefs and opinions. Social media companies therefore rely on algorithms (算法) to assess our interests and flood us with information that will keep our attention. The algorithms focus on what we “like”, and “share” to keep feeding content that makes us comfortable.
In order to truly get access to all information and to evaluate our media, we must give ourselves the opportunity to step out of our comfort zone. While this becomes increasingly challenging, there are things we can do. The first step is to beef up your media consumption sources. Adding in a few media sources with differing opinions will allow you to at least understand what people are saying outside of your echo chamber. Next, read each thing you see with a critical eye. Make sure that each thing you accept as truth is truly fact. Lastly, attempt to search out reliable new sources that are known for trying their best to leave out false information. By accepting that our media buffet on social media is a product of our present beliefs and opinions, we can work to make sure we are not simply stuck in a social media echo chamber.
1. What is a result of the social media echo chamber?| A．People contact like-minded online users effectively. |

| D．Accepting our present beliefs and opinions. |
| A．To call on people to use algorithms frequently. |
| B．To ask people not to take in information blindly. |
| C．To promote the use of various social media sites. |
| D．To inform people of new technology developments. |

8 . When my teenaged son became seriously ill, terrible times for my family began. Our once-happy home became tense and depressed. My husband and I were exhausted under the great stress of caring for my son. It was as if we forgot how to communicate-we couldn’t have a simple conversation without a fighting. Our marriage was on the point of breaking up.
One evening, my son and I were talking about gifts. I recalled my first Valentine’s present from my husband, a kazoo. I was awkward when I received it because I couldn’t get it to make a sound although I am a professional saxophone player. However hard I tried, it just never worked. The kazoo eventually got packed away and forgotten. But my son was interested and insisted on seeing it. After some trouble, I found it.
“You couldn’t get a sound? What’s so hard about it?” my husband asked, amazed. He took the kazoo and blew. Nothing happened. Surprised, he tried again. Still there was no sound. Frustrated, he tried again, only to produce a funny sound like an angry bumblebee trapped in the mouth of a bear. We burst into laughter. My son took a turn to play the kazoo. He did no better than us, causing more laughing.
Seeing his face light up, we felt as if the darkness had lifted and a ray of sunshine was let in. It was the best ten minutes of the past couple of years. The mood stayed light for the rest of the evening. It didn’t solve anything. But this experience with the kazoo brought some change in our hearts that always reminds us that there are still things to laugh at and enjoy, and that we can still connect as a family.
