参考答案及解析：
1.将height改为high/peak。整句话的大意为他们把男女的婚龄降了下来，使出生率达到了20世纪的高峰。high可以用作名词，意为“高峰”，“高水准”，“最高纪录”。height可以作“极点，顶点”解释。例如：Theheightofclevernessistoconcealone’scleverness。2.将第二个不定冠词a去掉。steadydecline意为持续的下降，前面不用加冠词。又如：yearsofhardwork。根据语感可以判断出来。3.在went后加on，或将went改为lasted。此处是“持续”的意思，所以可以用wenton或者last来表达。4.将high改为higher。此处意为美国人结婚率比以前提高了，有与战前相比的意思，因此应用比较级。5.将Europe改为European。6.删掉more。此处的大意为战后离婚率也下降了，这个现象不大有人注意，但同样也很重要。另外，more与equally相矛盾。7.将nevertheless改为also或者删掉nevertheless。此处上下文之间不是转折关系，而是递进关系。8.将that改为those。此处的代词应指marriages这个复数名词，因此应用those。此处考察代词与先行词一致的问题。9.将Since改为Although/Though/While。此处是转折关系，不是因果关系。10.将in改为to。短语totheextent是固定搭配。
