解答 48.from 考查固定短语.protect…from doing sth意为"保护…不做某事",句意:他们还保护土壤不被雨水冲走.故填from.
49.some 考查形容词.in some places意为"在一些地方",符合语境,故填some.
50.which 考查定语从句.根据空后的makes可知,此处做主语指代前面的句子,意为"这件事"是非限制性定语从句,故填which.
51.no 考查形容词.此处是形容词修饰名词land,意为"没有的",句意:为他们的后代留下没有绿色的土地.故填no.
52.Once 考查连词."森林生态系统被破坏"和"它不能被替代"之间存在假设关系,故用从属连词once,意为"一旦…就…".
53.but 考查固定搭配.固定搭配not only…but (also)…意为"不但…而且…",句意:不但地球的气候稳定性受到影响,而且即使是最小的植物和动物也经历了危及生命的变化.故填but.
54.their 考查形容词性物主代词.根据后面的名词homes,可知此处应用形容词性物主代词,代指动植物的,故填their.
55.bad/terrible考查形容词.根据后面的名词consequence可知应用形容词,由上文可知句意为:过度砍伐树木对人类和动物造成了不好的后果.故填bad/terrible.
