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.

2 . A new study published this week in the journal Nature Communications has concluded that a 100 percent change to organic (有机的) food production in England and Wales would actually lead to a great increase in greenhouse gas emissions (排放). In turn, this would contribute to further climate change.
Although organic farming directly pours out fewer emissions than conventional farming—around 20 percent lower for crops and 4 percent for farm animals—it produces notably less food. As to this study’s findings, total organic agriculture in England and Wales would produce 40 percent less food. With less food in the market, the countries would need to increase food imports, which would produce more global greenhouse gas emissions.
Organic farming also increases the amount of absorbing carbon, a process where carbon dioxide (CO2) is “absorbed” out of the atmosphere and captured by plants and stored in the soil. However, even a total change to organic farming would only be equal to a tiny part of the higher emissions from overseas land use.
“We predict a drop in total food production of 40 percent under a fully organic farming process, compared to conventional farming, if we keep to the same national diet,” Dr Adrian Williams, lead author and reader in Agri-Environmental Systems at Cranfield University, said in a statement. “This results from lower crop quantity, because output is limited by a lower supply of nitrogen, which is mainly from other crops or solid waste from cattle on the grassland.”
Nevertheless, it is important to note that organic farming still holds some useful benefits for the environment, such as reducing exposure to chemicals and improving the varieties of creatures. In conclusion, the study suggests that organic farming will continue to play a key role in resolving the world’s environmental problems. However, it’s just one part of a much wider solution.

3 . Reading instruction in the classroom is a key concern for all teachers and there are many ways to go about it. However, is our determination to achieve excellence in reading skills in our children killing their love and enjoyment of a good book?
In my work with parents, I am frequently asked the best ways to encourage reluctant readers to be engaged with books. Parents report that their children return home from school with no inclination to pick up a book and read.
Any eager reader will gladly talk about the joy with a good book to read away the hours on a cold, rainy afternoon. Reading a good book is one of life’s greatest pleasures. We need to share these experiences with our children in order to assist them in developing into strong readers. But the use of boring, mass-produced home reading texts in children’s early years at school can be seen as the beginning of this negative cycle.
As children progress through their schooling life, there are many other instances of learning reading skills that don’t help reading development. Frequently, teachers feel the pressure to give their students “just enough” in terms of reading strategies to be able to achieve the test, which leaves little time to focus on reading for pleasure.
Kelly Gallagher, a high school teacher, outlines the term “Readicide” in his book. He says it’s: the systematic killing of the love of reading, often worsened by foolish, boring practices found in schools.
Recent research shows that many teachers tend to follow the traditional literacy practices that they have experienced in their own education, which can often have negative intentions for their students.
While teaching children key concepts for analyzing and evaluating texts is important, the manner in which it is done and time that is spent on this can lead to unexpected results. Schools aren’t to blame when it comes to not arresting students’ lack of interest in reading, but they have an important role to play in fostering reading enjoyment.
