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 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush（灌木丛）in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.
Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy（树冠层）of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.
Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.
They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity（湿气）of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

3 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.
I decided to think up a method of dealing with forbidden fruit.
"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."
"What's that?" they asked.
"It's a large wooden chest full of toys for my grandchildren," I replied,
"You don't have grandchildren," someone said.
"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."
My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.
The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."
I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

Then we worked out a plan: When Christie takes one of her children out, I’ll watch her other three. And when she watches two of mine, I’ll take someone out.
The children were extremely quick to accept the idea of “Mommy and Me” time. Christie’s daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “She’s like a different child when there’s no one else around,” Christie shared with me quickly. With her mother all to herself, McKenzie didn’t have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering（口吃的）son, Tom, doesn’t stutter once during our activities since he doesn’t have to struggle for a chance to speak. And the other son, Sam, who’s always a follower when around other children shines as a leader during our times together.
The “Mommy and Me” time allows us to be simply alone and away with each child ---talking, sharing, and laughing, which has been the biggest gain. Every child deserves（应得到）to be an only child at least once in a while.

5 . More than 10 years ago，it was difficult to buy a tasty pineapple (菠萝)．The fruits that made it to the UK were green on the outside and，more often than not，hard with an unpleasant taste within.Then in 1996，the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowygold than green. It was slightly softer on the outside and had a lot of juice inside.But the most important thing about this new type of pineapple was that it was twice as sweet as the hitandmiss pineapples we had known.In no time，the Del Monte Gold took the market by storm，rapidly becoming the world’s bestselling pineapple variety，and delivering natural levels of sweetness in the mouth，up until then only found in tinned pineapple.
In nutrition (营养) it was all good news too.This nicetasting pineapple contained four times more vitamin C (维生素C) than the old green variety.Nutritionists said that it was not only full of vitamins，but also good against some diseases.People were understandably eager to be able to buy this wonderful fruit.The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a_fixture in the shopping basket of the healthy eaters.
Seeing the growing market for its winning pineapple，Del Monte tried to keep the market to itself.But other fruit companies developed similar pineapples.Del Monte turned to law for help，but failed.Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.

The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced（影响）us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.
