1.【答案】D。解析：考查时态和主谓一致。句意：男女比例已经发生改变，所以当今女性少于男性。主语中心词是proportion，所以谓语应该是单数，排除B和C;观察题干的时态得知，so that后面是一般现在时，所以前面应该用现在完成时表示对现在造成的影响，故正确答案为D。
2.【答案】A。解析：考查形容词辨析。句意：他的童年缺少幸福家庭所特有的和睦氛围。be typical of特有的，典型的;be short of短缺;be composed of由……组成;be economical of经济的，节约的。根据题干，typical符合句意。
3.【答案】A。解析：考查形容词辨析。句意：有人认为，应该为很小的孩子开设语言课，因为他们学新语言学得很快。be available to可被……利用或得到;be equivalent to相当于，等同于;be opposite to与……相反;be accustomed to习惯于。从后半句可以推断出是给小孩开设课程，所以是让小孩“能够得到”，所以选A。
4.【答案】C。解析：考查副词辨析。句意：平衡的饮食对我们的健康很重要;但是足够的休息也同样重要。excessively过分地，极度;properly合适地;equally同样地，同等程度地;generously慷慨地。只有equally符合句意。
5.【答案】C。解析：考查动词辨析。句意：该公司董事会决定扩大业务，将服装业务的各个方面都包括在内。multiply使相乘，使繁殖;lengthen使延长，使加长;expand扩张，扩大;stretch伸展，消耗(时间，金钱)。根据后面的include all aspects of the clothing business可以得知，空格处应该是表示“扩大业务”，expand符合句意，故正确答案为C。
