错或不一致。如：A. I usually got up at seven in the morning(got up应改为get up——由usually引导的句子谓语动词应用一般现在时)；B. At the party the film star sang a song for us and later dances for the aged(dances应该为danced——在并列句中，谓语动词时态多保持一致)。②主句与从句的时态不一致。如：He was a teacher before he became a manager of a big firm(was应改为had been——当教师的时间应在做经理之前)。语态方面的错误主要表现为主动语态及被动语态的混用等。如：A. I have never imagined that waste paper can use so widely(应改为can be used——纸张与利用之间应为被动关系)；B. Large masses of data must be generally undergone a process of summarization(应改为must generally undergo——此处主谓之间用主动更好)。
1.3 连接词错误
在六级考试中，连接词使用错误屡见不鲜，其内容主要包括在并列句或复合句中出现并列连词、从属连词或关系词的使用不当等。如：A. I invited him to
come to my office and he refused(并列连词and应改为but——前后有转折关系)；B. He looked at me even if I were something from outer space(从属连词even if应改为as if——从上下文的意思来看应用表示“似乎、好像”的as if); C. I read without discrimination everything which I happen to come across(关系代词应改为that——当先行词为all, everything, nothing, little, much等时，定语从句子只能由that引导)。
1.4 形容词、副词用法错误
形容词、副词用法错误主要包括：①形容词或副词使用不当。如：A. I frequently feel weakly and dissatisfied with myself(应改为weak——feel为系动词)；B. The cat ran quick as soon as he saw the dog(应改为quickly——run为实意动词)。②形容词、副词在原级、比较级、最高级方面的使用错误：A. 形容词或副词未用比较级形式。如：It is well-known that the sun is much big than the moon(应改为bigger——比较级前可以由many, much, a little等表示不定量的代词修饰)；B. 不可
分级的形容词、副词误用了比较级结构。如：But for some spelling mistakes, your composition would be more perfect(应去掉more——perfect没有比较级和最高级形式)；C. 比较级与最高级混淆。如：Of all the toys the boy saw in the window the thing he wanted more was a new watch(应改为most——在of all, of the whole等句子中应用最高级形式)；D. 比较级、最高级结构中的副词、连词、固定结构等方面的错误。如：a. The more you study during the semester, the lesser you have to do that before the exam(应改为the less——the less本身已是比较级形式)；b. This product is more inferior than the one you bought yesterday(应改为to——表示比较级时inferior后应加介词to); c. Everest is 3 times as high than the Matteriorn, the highest
mountain in Europe(应改为as——此处为“数词＋times＋as＋形容词原级形式＋as”同级比较结构)；E. 混淆句中用于比较的两个部分。如：The climate in the coastal cities is much warmer than in the interior cities(在than与in之间应加指示代词that——句中用于比较的两个部分是气候而不是地
区)。
1.5 虚拟语气用法错误
虚拟语气类错误主要包括：①主句或从句的动词形式未用虚拟语气形式。如：If we had more rain last summer, we would had a harvest(应改为had had与would have had——此句应用与过去事实相反的虚拟语气形式)；②混合型虚拟句中的主从句动词形式出现错误。如：If you had been older, I would have allowed you to go that day(应改为were——条件句可以指目前情况下的一种假设)；③在由表示“建议、要求、命令、坚持”等动词引导的宾语从句中，动词使用出现错误。如：The employer ordered that the letter would be delivered at once(应改为should be或be——在表示“建议、要求、命令、坚持”等动词引导的宾语从句中，谓语动词要用should加动词原型或直接用动词原型)；④特殊虚拟语气形式出现错误。如：Without the
radio-receiver, the large attention will be of no use(应改为would——由连词suppose, provided或介词without, but for等引导的句子谓语动词应用
