1. D【解析】数词、名词、形容词等词用连字符连接成的形容词中，名词都不要加s。
2. B【解析】数词+名词一起做定语时，如果数词与名词之间有连字符“-”，则用数词+单数名词+形容词结构，如果数词与名词之间没有连字符，就需要用名词所有格作定语。上面三道题的答案分别是5D，6D，7B。
3. 【解析】答案是A。本题主要是考查基数词和序数词的用法及转换。在编号中，用基数词时，均要大写字母开头，而且名词在前，数词在后；用序数词时，必须加定冠词，且每个单词的第一个字母都要小写。因此本句还可表达为The eighth lesson is the most difficult of the third book。
4.【解析】答案是B。“数词 + and +a half+名词复数”也可表达为“数词+名词（单数或复数）+ and a half”，如“一天半”可表达成one and a half days或one day and a half。这里C、D显然是错误的。A可更正为one and a half years' time，即year的复数所有格的形式。
5.【解析】这里C是错误的，应该更正为in the 1950s。年代应该用基数词的复数形式来表达，并在前面加定冠词。此外，数词的复数形式还可用来表示人的岁数，如： When he moved to Germany in the 1960s, he was already in his forties. 意为：他六十年代移居德国时，已经四十多岁了。
