Summary
The Super Strength of Spider Webs
The ability of fictional superhero Spider-Man to swing off city skyscrapers using his sticky web has fascinated many of us. But however amazing it appears to be, the superpower is unrealistic, right? Not completely, scientists say.
Spider silk is in itself a very strong material. In fact, it is about five times stronger than steel in weight-for-weight terms. Even so, this doesn’t thoroughly explain the strength of spider webs. It was not until recently that scientists discovered why spider webs are able to withstand huge forces.
The scientists found through a study that it is not just the remarkable strength of the silk spiders spin, but also a web’s intricate design that increases its durability. The creation of a typical web uses up a huge amount of a spider’s energy, so it contains a series of features which prevent major repairs from being needed.
Its complex structure means that when a single strand of web breaks, the overall strength of the web increases rather than weakens. Removing up to 10 percent of the threads from various areas made the web not weaker but actually up to 10 percent stronger. When a weight was applied, only one thread broke – so the spider could do minor repairs rather than start from scratch.
In previous studies, researchers also found the silk itself has an ability to soften or stiffen to withstand different types of loads – unlike any other natural or man-made fiber. In tests against three other materials made into similar webs, the spider silk was six times more resilient to damage when subjected to falling branches or high winds.
The scientists believe the findings could be used to help design a new generation of super strength materials. The intricate design of the spider web could be used in many areas of life to contain damage to a small area, said study co-author Markus Buehler, of the Massachusetts Institute of Technology.

How to Write an Effective Summary
The goal of writing a summary of an article, a chapter, or a book is to offer as accurately as possible the full sense of the original, but in a more condensed(缩减的) form. A summary restates the author’s main point, purpose, intent, and supporting details in your own words.1.
Read the passage carefully.
Determine its structure. Identify the author’s purpose in writing. After you finish reading, write down in one sentence the point that is made about the subject. 2.
Reread, label and underline.
Once you clearly understand the writer’s major point(or purpose) for writing, read the article again, underline the major points supporting the thesis. 3. In addition, underline key transitional(过渡的) elements which show how parts are connected. Omit specific details, examples, description, and unnecessary explanations.
Write, revise and edit
Now begin writing your summary. 4.Then write your summary, omitting nothing important, eliminating repetition, disregarding minor details, or generalizing them, using as few words as possible to convey the main ideas and striving for overall coherence through appropriate transitions. Conclude with a final statement reflecting the significance of the article.
Revise your summary. After you’ve completed a draft, read your summary and check for accuracy. Keep in mind that a summary should generally be no more than one-fourth the length of the original.
5.Correct grammar, spelling, and punctuation errors, looking particularly for those common in your writing. Write a clean draft and proofread for copying errors.

Mention the word superhero, and the images that come to mind are of fictional characters like Spiderman, Wonder Woman, or Batman. However, photographer Josh Rossi has used his camera to show the world’s real superheroes — young children who are battling severe diseases and disabilities.
The event leading to the creative project began in 2016, when Rossi fulfilled his then three-year-old daughter’s dream of becoming Wonder Woman. Thanks to the handmade costume and Rossi’s impressive Photoshop skills, the photoshoot instantly became a hit.
Since it was Wonder Woman that brought about the idea, Rossi decided to focus on the superheroes that will appear alongside her in the upcoming movie, Justice League. To make the photoshoot more meaningful to the kids, he matched each child with a superhero with whom they had the most in common.
The first member of the real-life “Justice League” was Kayden Kinckle. The five-year-old uses prosthetics (假肢) to walk because both his legs had to be cut off due to a born disorder. To Rossi, Kayden’s perfect superhero was Cyborg, who was a healthy boy before a terrible accident left him injured, forcing his father to keep him alive with robotic parts.
Teagan Pettit was born with only half a heart and has already gone through three open-heart surgeries. According to Rossi, the nine-year-old fits the bill for Superman because they both have a weak heart. The fictional superhero grows weak when near Kryptonite (氪), while Teagen’s half heart is too weak to control his body temperature. The photographer says, “Superman and Teagan both have hearts of steel!”
1.What led Rossi to begin his heartwarming project?
A.He was a big fan of superheroes.
B.He photographed his daughter as Wonder Woman.
C.He was asked by many parents to film their children.
D.He wanted to advertise the upcoming movie.
2.Kayden is similar to ________ according to Rossi.
A.Cyborg. B.Wonder Woman. C.Teagan. D.Batman.
3.What does the underlined phrase “fits the bill for” in the last paragraph mean?
A.loves. B.matches. C.orders. D.watches.
4.What can be a suitable title for the text?
A.A Superhero Photographer B.Fictional Superheroes
C.Fans of Superheroes D.Real-life Superheroes

The cheerful smiles and legendary strength of the Sherpas(夏尔巴人) have been an essential part of Mount Everest climbing expeditions(探险) from the very beginning. Indeed, very few significant successes have been achieved without them.
When Western mountaineers first set their sights on the world’s highest peak, they found in the Sherpas a people ideally suited to the hardship of high-altitude climbing, unfailingly positive, stout at altitude, and seemingly resistant to cold.
Sherpas did not venture into the high peaks until European mountaineers began arriving to climb in the world’s greatest mountain range. Mount Everest, known as Chomolungma or “Goddess Mother of the Land” to the Sherpas, was long considered as a living place of the gods where humans were not allowed to go.
Although Everest now sees many a human footprint, the Sherpas still regard the mountain as a holy place. All modern expeditions begin with a Puja ceremony in which Sherpas and other team members leave offerings and pay respect to the gods of the mountain, hoping to remain in their good graces throughout the climb.
Sherpas were first employed as porters, tasked with carrying large amounts of equipment to supply the military-style expeditions of the day. The early climbers were amazed at the strength of these people, from the fittest of mature men to the young and elderly. In addition to their heavy loads, some of the women even carried along their babies. The whole troop of Sherpas slept outside, using only rocks for shelter, as temperatures dropped well below freezing.
Stronger Sherpas soon graduated from porter status and began to undertake challenging climbing. Those who distinguished themselves were awarded the Tiger Medal, and many desired this honor and the higher pay rate it afforded. Despite the potential dangers, the Sherpa people remained enthusiastic about taking part in Everest expeditions, which even then were becoming an important source of income for a poor mountain folk.
1.Sherpas didn’t go into the high peaks before Europeans’ arrival mainly because ________.
A.they enjoyed staying at low altitudes B.they were short of proper equipment
C.they were unaware of their potentials D.they considered the mountain as holy
2.By mentioning the “rocks” in Paragraph 5, the writer emphasizes _______.
A.the intelligence of the Sherpas B.the challenges for the climbers
C.the physical ability of the Sherpas D.the wild landscape of Mount Everest
3.Which of the following can best describe the Sherpas according to the text?
A.Talented for high-altitude climbing. B.Adventurous and crazy about wealth.
C.Generous and willing to help climbers. D.Professional in treating altitude sickness.

When we think of leadership, we often think of strength and power. But what are these really, and how do they operate?
Leadership today is not about forcing others to do things. If this is even possible, it is short-term, and tends to backfire. If you order someone to do something against their will, they may do it because they feel they must, but the anger they feel will do more harm in the long-term.
Meanwhile, they will also experience fear. Fear causes the thinking brain to shut down, making the person unable to function at his or her best. If they associate you with this emotion of fear, they will become less functional around you, and you will have succeeded in making a very good employee or partner unable to perform effectively.
The way we influence people in a lasting way is by our own character, and our understanding and use of emotion. We can order someone to do something, which may be part of the work day; or we can employ them at the emotional level, so they become fully devoted to the projects and provide some of their own motivation. Today’s work place is all about relationships. Anyone works harder in a positive environment where he is recognized and valued. Everyone produces just a bit more for someone they like. Leaders understand the way things work. They know the pay check is not the single most motivating factor in the work life of most people.
The true strength of leadership is an inner strength that comes from the confidence of emotional intelligence — knowing your own emotions, and how to handle them, and those of others. Developing your emotional intelligence is the single best thing you can do if you want to develop your relationships with people around you, which is the key to the leadership skills.
1.When will an employee have a feeling of anger in the work place? (Within 7 words)
____________________________________________________________________
2.If an employee fears his boss, what will his performance be like? (Within 2 words)
____________________________________________________________________
3.How can a leader make his employees work harder? (Within 12 words)

4.What does the word “those” refer to in the last paragraph? (Within 4 words)
____________________________________________________________________
5.What is the key to developing a leader’s relationships with his employees? (Within 4 words)
