I could not find satisfying work even though I had a lot of experience and a master􀆳s degree. To my shame, I was driving a school bus and living with friends to save money. I had quit my rented apartment. I had been through many job interviews with no luck. One day, while doing my rounds through a suburban neighbourhood, I felt anger inside me and thought, “Why has my life become so hard?” Immediately after this internal scream, I puled the bus over to drop off a little girl. As she passed she handed me an earring, saying I should keep it in case somebody claimed it. It had the words “BE HAPPY” painted on it. Yeah, yeah, I thought. Then it hit me. I had been focusing only on what was wrong with my life rather than what was right! I decided then to make a list of 50 things I was grateful for. At first, it was hard, and then it got easier. One day I decided to list 75. That night I got a phone cal from the manager of a large hospital. About a year earlier I had designed a colege course on stress management. She asked me if I would do a one-day seminar for 200 hospital workers. I said yes and got the job. My day with the hospital workers was great. I got a standing ovation(起立鼓掌) and many more days of work. I know that it was because I changed my attitude to gratitude. The day after I had got the earring, the girl asked me if anyone had claimed it. I told her no and she said, “I guess it was meant for you then.” I spent the next year doing training workshops al around the Seattle area and then decided to risk everything and fly to Scotland. One month later I met my wonderful Scottish wife and best friend of 15 years now. “The best attitude is gratitude” has been my motto for years now and yes, it completely changed my life. ( )1.

On summer days, you always see them flying freely over flower gardens and wild fields. But, do you know how butterflies become the flying insects? It􀆳s one of the amazing wonders of nature.

After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings are filed with blood, and the beautiful, colourful butterfly spreads its wings and flies away.

However, rising temperatures may actualy cause snowstorms to dump more snow,” says David Robinson. He is a professor at a university in New Jersey. He studies climate(气候) change. Temperature change is one of the greatest changes in earth􀆳s climate change over a long period of time. It can happen naturaly or because of human activities, such as burning gas and coal. Burning these fuels produces carbon dioxide(二氧化碳) and other polutants into the atmosphere, which hold heat in the atmosphere, leading to warmer global temperatures over time. “But how could warmer temperatures lead to more snow? To get snow, you need moisture(水汽) and freezing temperatures(0 ℃ or less),” says Robinson. “Without moisture in the air, there is no precipitation (rain or snow).” Robinson says there are signs that snowstorms are becoming stronger. This is because of this connection between moisture and precipitation. “The warmer the air becomes, the more moisture it holds. So, if it􀆳s warming and stil cold enough to snow, you can get more snow,” Robinson says. Of the 10 biggest snowfals in the Washington, D.C., five have happened in the past 25 years, according to the NWS. During that same time period, average winter temperatures in the Washington, D.C. increased. In 1996, the average winter temperature was 1.8 ℃. In 2020, it was 6 ℃. Weather experts suggest that rising temperatures may make winter shorter and less cold. But for now, the snow is stil faling. One day, winter might not have any days below the freezing temperature. Once temperatures stay above freezing, snowstorms become rain. Until then, we might continue to see strong storms. According to Robinson, that time could come sooner than we think. He says, “When we look back, years from now, we may see that this was the breaking point.” ( )11. What is Paragraph 2 mainly about? A. When earth􀆳s climate changes. B. What causes rising temperatures. C. What produces carbon dioxide. D. How polution influences precipitation. ( )12. What wil the rising temperatures cause according to the text? A. Less coal. B. Drier weather. C. Longer winters. D. Stronger snowstorms. ( )13. What is the purpose of Paragraph 5? A. To introduce the Washington, D.C. B. To report the biggest 10 snowstorms. C. To support Robinson􀆳s ideas. D. To show the increase of temperatures. ( )14. What does Robinson think of the future rising temperatures? A. Impossible. B. Serious. C. Meaningless. D. Amazing. ( )15. Where is the text probably taken from? A. A science magazine. B. A storybook. C. A sci-fi novel. D. A travel guide. 四、 方框选词。(共5小题,每小题1分,满分5分) advice milion accept coach although 1.
