Here we look at the criteria of grammatical range and accuracy.
首先我们来看看评分标准之一的语法掌握与运用。
This is one of four criteria on which he will be tested. Look for the other three criteria in other videos.
评分标准共有四项。其余几项评分标准参见我们的其他课程。
This criteria focuses on the range and accuracy of the grammar demonstrated by the test taker.
语法掌握与运用考察的是受试者所表现出的语法掌握度和准确性。
For grammatical range, consider whether what you are describing is something that happened in the past, use past tenses;
至于语法掌握度，也就是考察你描述过去的事物时是否使用了过去时；
Is happening in the present? Use similar present tenses; or is predicting the future? Use a variety of future tenses.
描述当下的事物是否使用现在时；或者描述未来的事物时是否使用了各类将来时。
Sometimes you can use a combination of these different tenses,
有时这些时态可以结合起来使用，
for example,when analyzing an IELTS Task 1 diagram, note the time period being described and use the matching tenses.
比如，在分析雅思写作第一部分的图表时，要注意图表的时间范围，使用相应的时态。
When describing the information, demonstrating a range of written grammar might also mean using some of these tenses:
描述信息时要体现你掌握语法的程度，也意味着正确使用这些时态：
comparatives, conditionals, modal verbs and the passive tense, especially for Task 1 process descriptions.
比较级、条件句、情态动词、被动语态，尤其在概括第一部分某个过程的时候。
Look for our speaking and grammar download for examples of all these tenses.
请参看我们的口语和语法视频中关于这些时态的例子。
It's important to learn and practice a variety of grammatical tenses.
学习和练习使用各种语法时态很有必要。
In all writing tasks, also use a variety of complex structures.
在所有的写作考题中，还要使用一些较复杂的语法结构。
Complex structures are sentences with multiple bits of information.
复杂的语法结构指的是包含多个信息的句子。
