很多要求单项过6分的学生都会败在写作上，写作经常是千年5，万年5.5。 除了抱怨压分的主观因素，真正的原因到底是什么呢?老师带你深入剖析。
　　写作6分首先要求不能跑题。一旦跑题，可能5分都非常难，4.5分是经常见到的分数。其次，保证论点的论证能满足基本的逻辑，论证要充分。最后，不能出现太多的语法错误，确保句子的准确性。下边， 刘丽老师给大家列一列考生作文中的常见语法错误及犯错的原因。
　　1. The quantity of women workers keep stable from 1985 to 1990.
　　这个句子是小作文数据图中学生所写。此句明显有两个错误，一个是时态错误。小作文中如果数据是过去的，要采用一般过去时，所以此处要用kept.。第二个是动词 keep形式不对，这句话的主语是quantity。时态错误和主谓不一致是雅思考试写作和口语最常见的语法错误。
　　2. With developing of economy， the environment had deteriorated.
　　这里用了一个with 介词+名词短语，想表达伴随的概念。但是大家要牢记介词后边可以加名词、名词短语、动名词，构成介词短语以便做状语或者定语。但是developing of economy词性有问题。A of B是常见的表示所属的名词短语格式，翻译成B的 A, 这里要求 A和B必须都是名词。而developing 是形容词性质，所以应该改为 with the development of economy.。同样，我们还可以把with替换成as, 但是值得注意的是as 是连词，连词后边要加句子，所以可以写成as the economy develops。
　　3. Playing computer games waste parents’ hard-earned money.
　　这句话是经典的主谓不一致的错误。主句是playing computer games 动名词做主语，所以谓语动词要用单数加s。在写一个现在时的句子时，一定要注意主谓一致问题。主语是否是可数名词单数、不可数名词、动名词、不定式或是句子。如果是，并且句子中又没有使用情态动词，谓语动词要加s。
　　4. There are many people believe studying abroad is a good choice.
　　这句话之所以这样写，都是受汉语语意的影响。那“有”在英文中我们用there be/ have 都是动词概念，所以造成句子多谓语动词，这里的are/ believe/ is都是动词，但是句子believe 后边是个宾语从句，明显动词多了。
　　5. Government should take immediate measures to protect our environment.
　　可数名词不能单独使用。这里government 是可数名词，所以在句子中要么用governments, 要么特指the government。
　　6. University students receive training on job-related skills is necessary.
　　又是一句读起来朗朗上口，受汉语语意影响的句子。这个句子中有 receive 和 is 两个动词，但是没有涉及到从句。university students receive training on job-related skills 已经是个完整的句子，所以要用形式主语从句 it is necessary that university students receive training on job-related skills.
　　7. The number of female students in this university is higher than male students.
　　比较成份要一致。这句前边主语是the number， 后边比较对象是male students，所以正确的方式是 The number of female students in this university is higher than the number of male students. 或者The number of female students in this university is higher than that of male students.
　　8. Newspapers exert such tremendous influence that they cannot only bring about major changes to the lives of ordinary people but to the government’s decision.
　　Both ...and/ not only…but also/ A and B都属于并列结构，前后连接成份要一致。这句not only 后边是动词短语，but后确是 to the government’s decision。所以我们可以改成Newspapers exert such tremendous influence that they cannot only bring about major changes to the lives of ordinary people but affect the government’s decision。
　　9. Although teenagers may be included in family decisions, but they are not ultimately responsible.
　　这个句子的错误在雅思口语中经常见到，也是受汉语语意影响，但是在英语中although和but都是连词，在句子中只能有一个。同样because和so也是一个道理。
　　10. Which kinds of knowledge and skills should universities provide has been argued for many years.
　　语序错误。主语从句，宾语从句都可以用疑问词what/which/ whether 等引导，但一定要记住，后边加正常语序的句子。should universities provide 语序错误，应该是which kinds of knowledge and skills universities should provide has been argued for many years，是which kinds of 引导的主语从句。
