I thought to myself I could do this. I begged my mother to let me send for the kit . Two weeks later the kit arrived. The next three hours later, I returned home with no card and a pocket full of money shouting, "Mama, all the people couldn't wait to buy my cards!" A salesperson was born. When I was twelve years old, my father took me to see Zig Ziegler. I remember sitting in the dark hall listening to Mr. Ziegler raise everyone's spirits up to ceiling. I left there feeling like I could do anything. When we got to the car, I turned to my father and said, "Dad, I want to make people feel like that." My father asked me what I meant. "I want to be a motivational speaker just like Mr. Ziegler," I replied. A dream was born. Recently, I began pursuing my dream of motivating(inspire) others. I realized that everything I had accomplished -- the graduate degree, the successful sales career, speaking appointments, training and managing for a major fortune 100 company as a senior manager-- had prepared me for this moment. I told my boss who was a great leader I would leave the company though I might not reach such a height in career. He told me to proceed and he believed I would succeed. Having made that decision, I was immediately tested. One week after I gave notice, my husband was laid off from his job. We had recently bought a new home and needed both incomes to make the monthly mortgage payment and now we were done to no income. I even planned to turn back to my former company, knowing they wanted me to stay but I was certain that if I went back, I would never leave. I decided I still wanted to move forward rather than end up with a mouth full of "if onlys" later on. A motivational speaker was born. When I held fast to my dream, even during the tough times, the miracles really began to happen. In a short time period my husband found a better job. We didn't miss a mortgage payment. And...

Or the smell of barbequed meat reminds you of a night around a fire. Scientists know that smells can make people think of powerful memories. Wouldn't it be great to somehow save those memories? _ is exactly what Mark Crames, a businessman making perfumes , is trying to do. His company, Demeter Fragrance, makes more than 200 kinds of perfumes. "Imagine every smell in the world as a musical note," Crames said. "We try to join those notes to make a piece of beautiful music." He has made many perfumes and he got the idea from plays, storms and even animals. Everyday smells mean different things to different people. "A perfume called Poison Ivy might make you think of sadness or surprise," Crames says. "But it could make another person think of a great time at summer camp." Crames produces perfumes using a high-tech method called headspace technology. This month, Crames is making scent for Tootsie Roll and Junior Mints. Not every smell can be easily copied. "One of our most needed perfumes is a little dog's breath," he says. "But it is so chemically complicated that it's very hard to get." What scent would you like to bottle? A zoo? Or grandma's old house? Crames may be able to help you bring back your memories, so all you have to do is have a smell when you want to remember.

Read the following article and select the best answer. Article: The nuclear leak at the Fukushima power plant in Japan, which followed the deadly earthquake two weeks ago, has caused an unexpected reaction in China. A sudden panic buying of salt occurred in many areas of our country about a week after the disaster. Salt in these districts was almost bought up overnight. Some sellers wanted to make a fortune by raising the price. The panic buying was caused by two major rumors on the Internet: First, iodized salt can protect against radiation. Second, there might be a fall in sea-salt production following the nuclear pollution of the ocean. Such fears are not new. The same kind of panic happened with vinegar during the SARS outbreak and garlic in the time of the influenza period. How can rumors like this spread in such a large country as China? Chen Fang, a reporter with the China Youth Daily said that many Internet users say there is a "crisis of trust" in today's China. "Experts don't have enough credibility and people don't trust all government announcements, either." Chen said. However, Chen added that the rumors should not be exaggerated . Many salt-buyers didn't care; others simply failed to understand what experts and governments were talking about. They just did as their neighbors and friends did. It was a case of the blind following the blind - that was the real reason behind the big increase in the demand for salt. On March 20, the Ministry of Commerce said: "The panic buying of salt has stopped and the market is back to normal." He also said China has enough salt to satisfy demand. Now everything is back to normal, many want to return the salt they bought. But in the view of the Xinhua Daily Telegraph, "It is true that these people paid extra money to buy the salt, but they created the crisis in the first place and caused the price to rise." The newspaper continued: "So there is no reason why they should get the money back." Perhaps consumers should keep the salt to remind themselves that often rumors are without foundation.

Read the following article and select the best answer. Article: Special ships that create clouds by sending seawater into the air could be the cheapest way of dealing with climate change, new research has found. The technique, known as "marine cloud whitening", would create clouds above the Pacific Ocean that would have a cooling effect by reflecting sunlight away from Earth. Nearly 2,000 wind-powered ships would cross the sea, getting seawater and sending it up through tall tubes. " When you send saltwater into the air, you create bigger and whiter clouds, and thus reflect more sunlight back into space," said David Young from the group of the study. The paper by Professor Eric Bickel and Lee Lane looked into the costs of the projects. It found that cloud whitening would reduce the effects of climate change this century for no more than PS5.3 billion. This is only a small part of the PS150 billion that leading nations are considering spending to cut CO2 emissions each year. It is also more than 25 times cheaper than the PS140 billion cost of another project which would copy the cooling effect of volcanoes. The authors also compared the cost benefits that reducing temperatures would have. They found every PS1 spend on other ways would have PS15 of benefits, however every PS1 spent on cloud whitening would bring PS2,000 of benefits. These would include the human costs on health and the influence on other fields. David Young said, "Marine cloud whitening could achieve as much for the planet as CO2cuts would, but with much less cost." But he warned that these techniques shouldn't be considered as a long-period way to deal with climate change. " It's important to note that this technique wouldn't reduce CO2emissions or deal with the causes of global warming, but would cover its effects." he said. Question: Compared to other projects, cloud whitening _ . - has a greater effect on volcanoes - will bring more benefits - will benefit man's health most - can reduce temperatures in a better way
will bring more benefits
