Many people often lose their friends and they don't know how to keep a long friendship. So how can you keep a long friendship? The following passage explains very well about this matter. The first thing you need to do is to become a good listener. In this way, you show your friends that you are interested in their lives. You want to know more about them and you want to help them solve their problems. They will cherish the friendship more if they know you care about them. The next thing is that you should respect other people's privacy. People usually don't like others to know about their private life, so you should show respect toward their privacy. Sometimes, they need some suggestions from others, but this does not mean that others can know about their entire life. So respect for privacy is a must for keeping a long friendship. The third important thing is that you need to be able to forgive. You must remember that nobody is perfect in this world. It is important to forgive others not to blame them for the mistakes they have already made. You are not perfect either. Thus you need to apologize to others for the mistakes you may have made. Pay attention to the three things above, and you will be able to have long friendship. This passage is written to tell us _ . A) why a long friendship is important B) what we can do for our friends C) how to make friends with others D) how to keep a long friendship

Fed up with constantly having to recharge or replace batteries in your ever-expanding electronic devices? The solution may be just a few steps away. "Energy harvesting" promises to power countless consumer devices, often with nothing more than your body's movement or heat. Dozens of companies around the world already offer such products, but many experts believe the market for the technology could explode due to electronic devices being developed for the Internet of Things. "It's huge," said Graham Martin, CEO of the EnOcean Alliance, a San Ramon-based group of businesses that promotes wireless energy-harvesting technologies. With the Internet of Things expected to combine billions of devices, "if they are all battery-powered, we'll have a problem because there's not enough lithium in the world," he added. "So a lot of them will have to use energy harvesting." Among the most basic forms of the technology is body power. When certain materials are squeezed or stretched, the movement of their atoms creates an electrical charge. Automatic watches have employed the concept for decades, for example, by winding themselves when their user moves their arm. Now, the concept is being considered for a number of other devices. In a contest seeking visionary ideas for wearable technologies, Intel awarded $5,000 for a concept to change the temperature difference between a person's body and a special piece of clothing they'd wear into electricity for mobile devices. Using sound to power devices is another energy-harvesting variation. Stanford University engineers are testing smart microchips that create electricity from ultrasound to power implantable devices that can analyze a person's nervous system or treat their diseases. A textile research association in Spain is proposing to obtain electricity from radio waves that flow around everyone to power sensors sewn into clothes, which can monitor a person's heartbeat or other vital signs. Research firm IDTechEx has estimated that annual global sales of... What makes "energy harvesting" necessary according to the passage? A) The waste of lithium in the world. B) The increasing number of electronic devices. C) The development of technology. D) The pollution caused by batteries.

Q: At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it's sunny and brighten when a passing cloud blocks the sun. A wall of windows at a University of Pennsylvania engineering building has built-in blinds controlled by a computer program that follows the sun's path. Buildings are getting smarter and the next generation of building materials is expected to do even more. Windows could catch the sun's energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up. Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like "green roofs", where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out. As technologies such as sensors become cheaper, their uses spread. The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light. More new building materials and technology are in development. A Philadelphia building firm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so. _ will be developed and used in the construction industry. A) "Green roofs" that cool or heat buildings B) "Smart wrap" that catches the sun's energy C) Sunlight-measuring sensors that control lights D) Window coating that lets light in, but keeps heat out

In New York, Ma witnessed the Alibaba Group opening on the New York stock exchange with the largest initial public offering (IPO,) in American history. "Alibaba, the world's largest Internet commerce company makes China equal to the US in the rapidly increasing global competition for technological innovation and economic transformation " commented the South China Morning Post. It has also made Ma China's richest man with a fortune of around $25 billion (153 billion yuan), reported Reuters. It's reported that Ma's rags-to-riches journey is just as spectacular as his Internet empire. Ma failed the national college entrance exams twice before he was finally in Hangzhou Normal University on his third attempt and failed in finding a suitable job several times. Aslo, Mr Ma is a big believer in perseverance, which was proved in his English study experience. However, it was his vision and goals that launched his career. During a short trip to the US as an interpreter in 1995, Ma first experienced the Internet. He believed in the Internet's business potential when few other Chinese people did. He started Alibaba in his Hangzhou apartment, with 17 friends and $60,000 of funds. At the time, when e-commerce was unheard of in China, _ he once said, according to The Guardian. His unusual ideas earned him the nickname "Crazy Jack Ma" . Indeed, Ma is different. Although he is very thin and about 160cm tall, "Ma is yet animated and forceful, said The Guardian. "He is funny, creative, and a compelling speaker. Ma told Time magazine that he was "old for the Internet". He started to slow down and looked around. According to The Wall Street Journal, Ma "plans to open a tai chi club with the actor Jet Li, build an entrepreneur university in Hangzhou and continue to work on several environmental projects." What's the best title of the passage? A) The Development of Alibaba Group B) Ma Yun's Personal Life C) Ma Yun's Crazy Success D) E-commerce in China
