改错练习题

　　词性的使用错误
　　词性错误是最容易犯的错误之一，通常而言，对单词记忆不够全面以及受到汉语的影响等都会造成此类错误的产生。词性的使用错误是指文章中单词的词性用错，主要表现在名词形容词副词以及动词的使用错误上，如把名词错当成动词使用，或者把形容词错当成名词或者该用副词的地方错用了形容词等情况，归纳起来主要涉及三种类型：
　　名词与动词的错误使用 ，如： approval — approve ， sale — sell ; 名词与形容词的误用 ，如： medicine — medical/medicinal ， emotion — emotional ; 形容词与副词的误用 ，如： high — highly ， mere — merely 等。这类错误还常出现在 be 以外的系动词后，如： feel badly — feel bad ， grow uneasily — grow uneasy .
　　例 1
　　Ideally, of course, the expression of editorial
　　opinion should be limited on the editorial page
　　and the news articles should be objective
　　— telling the fact as complete as possible. 1.__________
　　该句中complete为形容词，而在该句中它前面所接词为动词tell，必须改为副词形式，故应该将complete改为completely.
　　例2
　　It is a social prejudice that the work of street
　　cleaners is thought to be dirty and shame by 1.__________
　　most people.
　　根据上下可知该句中的系动词be后面必须接形容词，且与前面的dirty并列关系，所以应该将名词shame改为shameful.
　　例3
　　It is true that their work may be dirty, but not
　　necessary shameful. What would our streets 1.__________
　　be like if nobody cleared away the rubbish?
　　该句中shameful为形容词，前面必须使用副词修饰，故应该将necessary改为necessarily.
　　例4
　　Used wise, science may increase our energy and 1.__________
　　food supply, improve our health, expand our joy
　　and extend our lives.
　　该句的完整结构是“if it is used wisely, science may… ”，“wisely”修饰过去分词“used”，表示“使用得当”的意思。所以应该将形容词wise改为副词形式的wisely.

参考答案

　　答案解析：
　　1. high→highly.
　　2. relative→relatively.
　　3. easily→easy.在该句中easy紧跟在系动词be之后，与clear并列，即“your speech is clear and easy to follow”。
　　4. late→later.
　　5. high→height.“in height”表示“在高度上”的意思，为固定搭配，没有in high的表达法。
　　6. costlier→costly.costly是形容词，意思是昂贵的，它的比较级是more costly，costlier是错误形式。
　　7. necessary→necessarily.
　　8. medicine→medical.
　　9. worth前加are.本句有一个由“when”引导的时间状语从句，主句“Clearly some risks worth taking”缺少谓语动词，因为worth是形容词，一般于“be worth doing”。
　　10. minutes→minutes'.本句中minutes是名词，不能直接修饰后面的名词delay，应该用名词所有格形式。
