The nine-years-old girl can sing twelve English songs.
〔解析〕数词+名词+形容词构成的合成词时名词要用单数,所以nine-years-old应改为nine-year-old。
2. 派生词容易出现的错误:单词的前缀或后缀记忆不清;不能从句子的意思准确判断出用哪一个派生词。如:
The boy became ______ (home) after his parents died two years ago.
〔解析〕易误用inhome。出现错误的原因是随便给home加了表示否定的前缀。在此句中应该用派生词homeless表示“无家可归”的意思。
Your teacher was very ______ (happy) because you forgot your homework.
〔解析〕易误用happily。出现错误的原因是不能理解某些后缀或前缀的作用和意义。在此句中派生词unhappy表示“不高兴”的意思,而happily是副词“高兴的”,只有用unhappy才能和整个句子的意思保持一致。
The radio says it will be _____ (rain) this afternoon. You’d better take your raincoat.
〔解析〕易错用raining。出现错误的原因是认为be后面用现在分词构成现在进行时,在此句中用派生词rainy和be连用构成系表结构表示“下雨的天气”.
