69.D infer表示“推断”，explain指“解释”，interpret表示“解释、说明”。这里选express(表达)最符合文意。
70.B 见71题。
71.C 这两题放在一起来分析。原文意思应是：“人类拥有能把话语细分成单词的某种结构，而动物却没有。”70题的encourage(勇敢)，enforce(强迫)，ensure(保证)都不符合题意。而71题，比话语更小的单位应该是words。故此题选C。
72.A 此题考查上下文理解。下文举例说明的部分提到将一句话的某个词换成另外的词，由此推断可知，此处选择replace(代替)。
73.C 表达用另一个词代替，用another。
74.B 此题考查上下文理解，会说一句话和能够把这句话里的某个单词用别的词替换，这之间表达的应是一种并列关系。故选B。
75.C 此题考查非限定性定语从句，必须用which。
76.C 动物发出的声音不能形容为“标记”、“记号”或是“手势”，因此，只有signal信号才是正确选择。
77.A 此处考查固定搭配。in point指“适用的，相关的”
78.A 作者将山雀能发出20种叫声与人类语言能发出更多的声音相比较，这里应该选择转折连词：whereas(然而)。
79.C 参照上题，此处将人能发出的声音数量与动物进行比较。boundless(无界限的)，changeable(多变的)，ceaseless(不停歇的)，因此，正确选项是C。
80.B 根据上文，动物只能发出有限的声音，那它们的叫声显然只能是相似的了。因此，B是正确答案。

小结：
从以上这几个表格可以总结，近几年的大学英语四级考试的完型填空部分重点考查词汇，其次是固定搭配，然后是某些常用连词和介词的用法，最后可能涉及某一个语法结构，而定语从句的关系代词又是最常考的。
而这次考查的固定搭配是：by means of(以……的方式)，differ from(与……不同)和in point(相关的)。连词包括：but，and，whereas，其中以表达转折的连词考的居多。

It’s an annual backtoschool routine. One morning you wave goodbye, and that 71 evening you’re burning the latenight oil in sympathy. In the race to improve educational standards, 72 are throwing the books at kids. 73 elementary school students are complaining of homework 74. What’s a wellmeaning parent to do?
As hard as 75 may be, sit back and chill, experts advise. Though you’ve got to get them to do it, 76 helping too much, or even examining 77 too carefully, you may keep them 78 doing it by themselves. “I wouldn’t advise a parent to check every 79 assignment,” says psychologist John Rosemond, author of Ending the Tough Homework. “There’s a 80 of appreciation for trial and error. Let your children 81 the grade they deserve.”
Many experts believe parents should gently look over the work of younger children and ask them to rethink their 82. But “you don’t want them to feel it has to be 83,” she says.
That’s not to say parents should 84 homework—first, they should monitor how much homework their kids 85. Thirty minutes a day in the early elementary years and an hour in 86 four, five, and six is standard, says Rosemond. For juniorhigh students it should be “ 87 more than an hour and a half,” and two for highschool students. If your child 88 has more homework than this, you may want to check 89 other parents and then talk to the teacher about 90 assignment.
