unit 1 festivals around the world grammar课时作业第一节 阅读理解the amount of carbon taken in by growing plants increased from 1982 to 1999 as temperatures rose and the amount of carbon dioxide in the atmosphere increased. but a new study in fridays edition of the journal science found a droughtrelated decline in such plant growth from 2000 to 2009，even though temperatures continued to climb. as drought caused by warming reduces the lands ability to take in carbon，the result could be more carbon dioxide left in the atmosphere，and thus more warming，zhao maosheng，from the university of montana explained in a telephone interview. “this is a pretty serious warning that warmer temperatures are not going to endlessly improve plant growth，”co-author steven running，also from the university of moutaua，said in a statement. “we see this as a bit of a surprise，and potentially significant on a policy level because previous interpretations suggested global warming might actually help plant growth around the world，”he said. instead，he and zhao found a small but measurable decline of about 1%，compared to a 6%increase in the past decade. their study，based on the data collected by nasa satellites，found that north areas continued to increase plant growth，thanks to warmer temperatures and a longer growing season. someone commented，“this past decades net decline in earthly productivity suggests that a complex relationship between temperature，rainfall，cloudiness，and carbon dioxide，probably in combination with other factors such as nutrients and land management，will determine future patterns and trends in productivity. 1from the first paragraph，we can learn _ in the recent decade or so. athe emission of carbon hasnt been reducedbdrought has been causing loss of soil and waterccarbon dioxide levels have been risingdthe rise of temperature doesnt promote the plant growth答案d解析细节理解题。由文章第一段中的“a droughtrelated decline in such plant growth from 2000 to 2009，even though temperatures continued to climb”可知近十年气温的上升并没有促进植物的生长。2zhao maosheng really worried that _amore and more land will be abandonedbthe climate becomes warmer and warmercthe emission of carbon dioxide

minutes and a few hours. this kind of loneliness is not serious. in fact, it is quite norml. for some people，though，loneliness can last for years. now researchers say there are three different types of loneliness. the first kind of loneliness is temporary. this is the most common type. it usually disappears quickly and does not require any special attention. the second kind of situationfor example，family problem，the death of a loved one，or moving to a new place. although this kind of loneliness can cause physical problems，such as headaches and sleeplessness，it usually does not last for more than a year. the third kind of loneliness is the most severe. unlike the second type，chronic(the opposite of“temporary”)usually lasts more than two years and has no specific cause. people who experience habitual loneliness have problems socializing and becoming close to others. unfortunately，many chronically lonely people think there is little or nothing they can do to improve their condition. psychologists agree that one important factor in loneliness is a persons social contacts，for example，friends，family members，coworkers，etc. we depend on various people for different reasons. for instance，our families give us emotional support，our parents and teachers give us guidance, and our friends share similar interests and activities. however, psychologists have found that，though lonely people may have many social contacts，they sometimes feel they should have more. they question their popularity. psychologists are trying to find ways to help habitually lonely people for two reasons：they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness as heart disease, while temporary and situational loneliness can be a sad，and sometimes dangerous condition. loneliness and diseasethree differenttypes of _1_the most common type is _2_it disappears quickly and _3_ no special attention. the second type is situation，which
