案例背景：书面表达在新课标高考英语试卷中占25分，在高考中所占分值较大，但想在一篇100词左右的文章中把自己的水平发挥到极致并非易事，它一直是高中生较头疼的一个东西。鉴于此，有必要对学生在表达过程中常犯的错误进行一个总结并提出一些改进办法，所以笔者有一些拙见。
案例分析及解决措施：新课标全国卷书面表达要求100词左右，其实也就是10个句子左右，说起来不难，但学生一写，总是漏洞百出，不忍直视。
一.主谓不一致 例如：
a. A number of students is going to learn a foreign language.
b. He go to school by bike every day.
c. The teacher, with all his students,are going to have a picnic this weekend.
由于汉语的动词不受主语的人称和数的影响，而英语的谓语动词要和主语保持一致，谓语动词要随着主语而变化。学生往往用汉语思维，不考虑主语是第几人称，是单数还是复数。
二.时态不对头 例如：
a. A baby can cry as soon as it was born.
b. I spend 50 yuan buying the clothes.
c. I will not come here if it will rain tomorrow.
学生在写作中经常在时态方面犯错误。英语时态种类繁多，动词的构成形式随着时态的变化而变化。中文里没有时态区分。动作或动词的时间由跟在动词后的诸如 “着”、“了”、“过”等副词小词来表示。实际上，学生在头脑里很清楚语法规则，但经常混淆或忘记改变动词的词形。
注意：写议论文一般用现在时态。举例，提到过去的事用过去时。写日记则一般都用一般过去时。例如：
Not only can it set my mind at rest, but broaden my horizons.(观点句用现在时)
Years ago, some of the tourists paid no attention to environmental protection.（具体事例经历过去时）
三.表达太单一
句式多变，语法灵活，是高考英语高分作文的重要特征，也是彰显考生深厚的语言功底的表现，所以遣词造句能力在英文写作中是非常重要的。句式单一，读者读起来枯燥生硬，好的英语句子令人赏心悦目，能增添作文亮点，因此要想写出漂亮的书面表达，必须从写好句子开始。下面的例子包括简单句和修改句子的三种行之有效的办法。
方法一：合并句子
1. It was early in the morning. Mr. Smith was in his garden. He was watering flowers.
Early in the morning, Mr. Smith was watering flowers in his garden.
2. A girl was crossing a road. The girl was pretty. The road was wide.
A pretty girl was crossing a wide road.
方法二：一句多译
这本书花了我300元。
The book cost me 300 yuan. \I spent 300 yuan on the book. \ I paid 300 yuan for the book. \The price of the book is 300 yuan. \It cost me 300 yuan to buy the book..
方法三：改写句子
1 Mr. Green is a tall man, who wears a pair of thick glasses. (定从变介词短语)
Mr. Green is a tall man with a pair of thick glasses.
2.The ice on the lake is too thin for us to skate on. (用so…that…结构改写)
The ice on the lake is so thin that we can’t skate on it.
四.文章不连贯
评分标准指出，书面表达应该注意“上下文的连贯性”，并能“有效地使用语句间的连接成份，使全文结构紧凑”。这里说的连贯性，就是指通过连接词（包括并列连词，从属连词和连接副词）使两个或多个意义相互关联的事情或观点在同一个句子内得以表达，从而使整个段落或篇章浑然一体，连贯流畅。
a.连接性副词
连接性副词称为过渡词。它们的位置一般以句首居多。连接性副词承上启下，能够令读者对后续的句子产生心理上的期待和准备，因此整个篇章会因它们而紧凑连贯。常见的连接性副词有：also, furthermore, in addition, additionally, hopefully, meanwhile, however, instead, in other words, in brief, in a word, in my opinion, on the whole等。如：
1.We have many things to do. We believe we can finish before the day is over.
We have quite a lot to do. Hopefully, we will be able to finish before the day is over.
2.The boy comes from a poor family. The boy does very well in his studies. The boy plans to work his way through college.
Even though he comes from a poor family, the boy does very well in his studies; furthermore, he plans to work his way through college.
b. 使用从属连词
常见的从属连词有after, as, when, while, as long as, as soon as等。如：
1.You work hard and never give up. You will succeed in your studies.
So long as you work hard, you will succeed in your studies.)
2.The teacher came in. the students were quiet.
The students were quiet as soon as the teacher came in.
五.汉式思维浓 例如：
1) 变化的原因有三点。
(误)The reasons for this change has three points.
(正) There are three reasons for this change.
2) 这样我的英语水平就提高了。
(误) My English level has improved.
(正) My English has improved.
3)如果你方便的话，请帮我寄一下这个包裹.
(误) If you are convenient, please send the parcel for me.
(正)If it is convenient to you, please send the parcel for me.
究其原因，笔者认为学生应该明白写作时是从英语到英语，用英语中本有的词汇和句型去表达自己想表达的意思，而不是从汉语到英语，用英语死劲儿去翻译汉语句子，这样势必会生成很多无法理解的汉式英语，结果事倍功半。
案例反思：
上述是笔者在长期的教学中得出的一点感悟，只能反映学生在写作时存在的部分问题。怎样能把一篇文章写好，写充实，后续还需继续完善，加之时代不同，学生不同，存在问题也会不尽相同。所以说与时俱进，因材施教，方为王道。
