语法复习十六：数
词
13．答案为A。表增加或减少的数量的百分比，用by+百分数表示。 14．答案为A。不可数的名词的百分比用单数；可数名词的百分比则用复数。C项时态不对，另如：90 percent of the population here are peasents．这个句子中population的意思是people． 15．答案为A。"dozen"与数词或many，several等词连用时复数一般不加s，故B、C两项不选。此外，dozen与数词连用做定语，一般也不加of．当然也有例外：Place them in dozens on the table．dozens表数量很多。Two dozen of these are wanted．dozen后面有of因为有限定词these，the等。Dozens of people were here．dozens of也表示"很多"。 16．答案为B。"半打"的表达方式一定要用"hall a dozen"。 17．答案为B。score做定语修饰名词用a(three)score of，而不用复数形式；常用"scores of"为其复数形式，意为"大量"，但有：three score and ten，a score or more 18．答案为B。"hall"起副词作用，修饰过去分词"done"，因为这个过去分词表状态，故"half"应在"done"前。再如：well done，well known，不用a half修饰done，故不选C、B两项。 19．B意为"同时"，不是"立刻"。 20． B 2l．A 如：tens of thousands of(小数在前，大数在后)thousands and thonsands of(两数一样大)。 22．B 居住的门牌号用介词at+号数+街道名"。 23．A 24．答案为D。"walk"作为名词，常与不定冠词连用。注意：在表数量的合成词中，名词部分为单数，如：a two-year-old boy． 25．答案为B。"在20世纪40年代"，必须有定冠词"the"．此外，年代后要加's或s。"他已经40多岁了"要用in his forties。 26．答案为B。dozen与数词或多或少several, many连用时，复数不加s。dozens of表示数量很多，在修饰有these，the等词限定的名词时，可用dozen of的形式。如：three dozen of these eggs.
