Changes in climate that had already taken place are manifested __1__from the decrease in extent and thickness of Arctic sea ice, perma- __2__frost thawing, coastal erosion, changes in ice sheets and ice shelves, altered distribution and abundance of species. __3__Nowadays snows melt earlier in the springtime. Lakes, rivers and bogs freeze much more later in the autumn. Reindeer herding __4__becomes more difficult so the ice is weak and may give way. __5__Nowadays winters are much colder than they used to be. __6__Occasionally during winter time it rains. We never expected this;we could not be ready for this. It is very strange. The cycle of the yearly calendar has been disturbed greatly. Warming over northern land areas has been very greater than elsewhere in the world. The __7__changes are due to human modification of the concentration of greenhouse gases during the 20th century, leading quite directly to the projections the Artic will warm by several times as much during the __8__
21st century as it did during the 20th century. The amplified warming in Arctic, in turn, directly contributes to overall global warming, as __9__well as cause changes that create impacts over the rest of the globe. __10__
In recent years a new farming revolution has begun, one that involves the 【21】______ of life at a fundamental level—the gene. The study of genetics has 【22】______ a new industry called biotechnology. As the name suggest, it 【23】______ biology and modem technology through such techniques as genetic engineering. Some of the new biotech companies specialize in agriculture and are working feverishly to 【24】______ seeds that give a high yield, that 【25】______ diseases, drought and frost, and that reduce the need for 【26】______ chemicals. If such goals could be achieved, it would be most 【27】______ . But some have raised concerns about genetically engineered crops.
In nature, genetic diversity is created within certain 【28】______ . A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, 【29】______ usually involves taking genes from one species and inserting them into another 【30】______ to transfer a desired Characteristic. This could mean, for example, selecting a gene which leads to the production of a chemical with antifreeze 【31】______ from an artic fish, and inserting it into a potato or strawberry to make it frost-resistant. 【32】______ , then, biotechnology allows humans to 【33】______ the genetic walls that separate species.
Like the green revolution, 【34】______ some call the gene revolution contributes to the problem of genetic uniformity—some say even more so 【35】______ geneticists can employ techniques such as cloning and 【36】______ culture(培养), processes that produce perfectly 【37】______ copies. Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new 【38】______ , such as the effects that they may have on us and the environment.
