A student, Kishanth, asked me about two of the points in the grammar criterion for band 8 writing (both task 1 and 2):
Kishanth學(xué)生問了我一個(gè)關(guān)于8分寫作的語法評分標(biāo)準(zhǔn)的問題（同時(shí)適用短作文和長作文）：

uses a wide range of structures
語法結(jié)構(gòu)使用廣泛
the majority of sentences are error-free
大部分語句無誤

Here's the problem with these two points:
對以上兩點(diǎn)有這樣一個(gè)問題：

When you try to use a wide range of grammatical structures, you risk making more mistakes (errors). But to reduce the number of mistakes, you might have to simplify your sentences.
使用多種語法結(jié)構(gòu)會(huì)面臨出更多錯(cuò)的風(fēng)險(xiǎn)。但為了少出錯(cuò)，可能不得不使用簡單的句子。

So what should you do?
我該怎么做？

My advice is this: Forget about the 'wide range of structures' point. If all of your focus is on using complex grammar, you'll probably do something worse than just make mistakes; you'll probably forget to answer the question properly. The people who worry most about grammar usually?neglect?task response,?coherence?and vocabulary.
我的建議是：別管“語法結(jié)構(gòu)使用廣泛”。如果你把全部注意力放在使用復(fù)雜的語法上，你可能會(huì)遇到比犯錯(cuò)更糟的事。你可能忘了正確回答問題。最擔(dān)心語法的人往往忽略了任務(wù)完成情況、連貫和詞匯。

For me, grammar is the least important criterion to worry about. I tell students to focus on the other 75% of the scoring system: task response, coherence and vocabulary. However, if you want my tip for improving your grammar score, I'd say that it's better to focus on reducing errors. I think examiners notice errors more than they notice grammatical range, and if you write a mix of short and long sentences, you'll probably fulfil the 'wide range of structures' requirement without realising it.
對我而言，語法是最不需要擔(dān)心的評分標(biāo)準(zhǔn)。我告訴學(xué)生，把心思放在剩下的75%評分上：任務(wù)完成情況、連貫和詞匯。然而，如果你想知道我的提高語法分?jǐn)?shù)的技巧，我建議你把重點(diǎn)放在減少錯(cuò)誤上。我認(rèn)為，相比語法范圍，考官對錯(cuò)誤更為在意。而且，如果你能混合運(yùn)用長句和短句，你可能沒發(fā)現(xiàn)自己其實(shí)已經(jīng)符合了“語法結(jié)構(gòu)使用廣泛”這一標(biāo)準(zhǔn)。
