Of all the changes that have taken place in English-language newspapers during the past quarter-century, perhaps the most far-reaching has been the inexorable decline in the scope and seriousness of their arts coverage.

Yet a considerable number of the most significant collections of criticism published in the 20th century consisted in large part of newspaper reviews. To read such books today is to marvel at the fact that their learned contents were once deemed suitable for publication in general-circulation dailies.

[单项选择]Climate change might force changes in diets around the world as certain staple foods become harder to produce, according to international agriculture researchers. However, future shortfalls could be offset by switching to crops which can thrive in those altered climates, according to new reports by the Consultative Group on International Agriculture Research.
Important crops like maize and wheat produce less grain at temperatures above 30 degrees Celsius."Those kinds of temperatures are being reached on a regular basis and more frequently in many countries now," says Sonja Vermeulen, head of CGIAR climate change research. Vermeulen says growing-season temperatures are not the only factors affected by climate change. Rainfall patterns are shifting, too. Water supplies will be strained in some areas, while others will see more floods.
Climate change is also altering habitats for pests and diseases, she says."And for some crops, particularly crops we really value, such as potato

[简答题] Coping with Climate Change What we have learned so far about how climate changes is affecting our global environment. Studies show that it adversely affects human and natural systems by reducing biodiversity, impairing biological and chemical cycles and making it more difficult to restore degraded ecosystems. Climate is not the only factor in the deterioration of natural systems. We are making big changes to the landscape, altering land use and land cover in major ways. These changes combined present a challenge to environmental management. Adaptive management is a scientific approach to managing the adverse impacts of climate and landscape change. Nature and Impacts of Climate Change Every week it seems there is an article about global warming in the news media. It may be difficult for some to grasp the big picture of the issue, but in general, climate change has already or is expected to --increase temperatures, particularly in the
