The climate in Africa is【C8】______ tropical in nature, which is broadly【C9】______ into three main climatic zones:【C10】______ equatorial, dry, and temperate(温带). Within these zones, altitude and other localized【C11】______ also produce distinctive regional climates.
Climate change,【C12】______ indicated by prolonged drought is one of the most serious climatic【C13】______ affecting the agricultural sector of the continent. As most of the agriculture activities in African countries hinges on rain fed, any adverse changes in the climate would likely have a【C14】______ effect on the sector in the region.
【C15】______ changes in the climate may affect the whole continent, its【C16】______ may vary across the continent. In northeast Africa, more intense dry periods and shorter wet seasons are expected to affect even huge river systems such as the Blue Nile, leading to serious water shortages and【C17】______ consequences to the agriculture and forestry sectors throughout the region. East and Central Africa will also see its agricultural【C18】______ decline. Coastal areas may also be affected by rising sea levels and intrusion of salt water into inland freshwater resources. The staple food for the region, maize, is particularly susceptible to drought. Wetlands of international importance and wildlife are also under threat from【C19】______ in Southern Africa. Climate change, therefore, is expected to worsen the food supply,【C20】______ , exacerbate the widespread poverty in the region.

The European Union had approved a number of genetically
modified crops until late 1998. But growing public concern
over its supposed environmental and health risks led several 【M1】______
EU countries to demand a moratorium (暂时禁止) on imports
of any new GM produce. By late 1999 there were enough such
country to block any new approvals of GM produce. 【M2】______
Last year, America filed a complaint at the WTO about the
moratorium, arguing that it was an illegal trade barrier
because there was no scientific base for it. 【M3】______
As more studies have been completed on the effects
of GM crops, the greens' case for them has weakened. 【M4】______
Much evidence has emerged of health risks from eating 【M5】______
them. And, overall, the studies have shown that the
environmental effects on modified crops are, not always 【M6】______
as serious as the greens claim. Nevertheless, environmentalists
continue to find fault of such studies and argue that 【M7】______
they are inconclusive.
While Americans seem happy enough to consume food made
from GM crops, opinion polls continue to show that European
consumers dislike the idea. Europeans seem be taking the attitude 【M8】______
which, since there remains the slightest possibility of adverse 【M9】______
consequences and since it is clear how they, as consumers, benefit 【M10】______
from GM crops, they would rather not run the risk.

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 interior of continents, toward the poles and in winter
？boost precipitation (降水量) in wetter areas and suppress precipitation in drier areas
？increase rain and decrease snow
？lessen peak spring runoff and cause more even year-round flows of water, thereby reducing water availability during summer irrigation and navigation seasons
？increase evaporation of water during the summer
？enhance the likelihood of lower mean lake levels, drier wetlands, and water shortages, particularly in mountain regions
？raise the frequency and magnitude of extreme weather events, such as hurricanes, tornadoes, and floods
？raise global sea levels, causing some populated coastal areas to become inundated (被淹没的)
？reduce the extent and duration of Arctic sea ice with adverse consequences for marine mammals
？increase the loss of glaciers in middle and equatorial latitudes, including premier mountain ecosystems such as Glacier National Park in Montana
Global average temperature has increased by about 0.6℃ over the past 100 years, with a major warming upswing in the 1970s. Warming is the result, in part, of rapid increases in emissions of greenhouse gases (GHG), particularly carbon dioxide (CO2), which is a byproduct of the combustion of fossil fuels, such as coal, oil, and natural gas, used for power generation and transportation.
When global temperatures rise and precipitation patterns change, it is expected there will be consequences on ecosystems, such as an increase in the spread of exotic species; redistribution of plants, animals, energy, water, and nutrients; alteration of natural processes and the structure and function of ecosystems.
Northerly latitudes are particularly vulnerable to climate change. The Arctic Council, an intergovernmental forum for Arctic nations and indigenous people, reported that the northern ice cap is warming at twice the global rate and the Arctic region is expected to warm at two to three times the rate for the rest of the world. Arctic warming will have serious consequences on human and ecology.
Nature and Impacts of Landscape Change
Landscape change results from natural disturbances and human activities. Natural disturbances include fire, windstorms, avalanches, landslides, tree fall, floods, and insect epidemics. Human activities causing landscape change include conversion of forestland to agriculture, drainage of wetlands, and forest fragmentation from road construction and timber harvesting.
Human activities often have a more significant effect on landscapes than natural disturbances because they alter the availability of energy, water, and nutrients to ecosystems; increase the spread of exotic species; accelerate natural processes of ecosystem change; and adversely affect the structure and functioning of ecosystems.

As they grow older, many children turn aside from books without pictures, and it is a situation made more serious as out culture becomes more visual. It is hard to wean children off picture books when pictures have played a major part throughout their formative reading experiences, and when there is competition for their attention from so many other sources of entertainment. The least intelligent are most vulnerable, but tests show that even intelligent children are being affected. The response of educators has been to extend the use of pictures in books and to simplify the language, even at senior levels. The Universities of Oxford and Cambridge recently held joint conferences to discuss the noticeably rapid decline in literacy among their undergraduates. Pictures are also used to help motivate children to read because they are beautiful and eye-catching. But motivation to read should be provided by listening to stories well read, where children imagine in response to the story. Then, as they start to read, they have this experience to help them understand the language. If we present pictures to save children the trouble of developing these creative skills, then I think we are making a great mistake.
Academic journals ranging from educational research, psychology, language !earning, psycholinguistic, and so on cite experiments, which demonstrate how detrimental picture a
