虚拟语气—雅思写作提建议常用时态

虚拟语气是考生们在雅思写作中用的比较少的一类时态，正因为用的少，所以也就成了亮点句型、句型。而在写作中，如果加入一两句虚拟语气，比如在论证的时候从反面进行阐明观点，有时候更加具有说服力。所以老师指出在使用虚拟语气的时候的常见易错点。
1、It is (high) time (that)…后面加动词的一般过去时，或者是 should（不能省）+ 动词原形，表示“（现在）该…”。
如：It is time that we did something to protect our environment.
It is time we left/should leave.

2、在demand，require，suggest（表示建议），insist，order，request，command等这类表示命令、要求或者提出建议的词汇后面，加上that + should（可以省）+ 动词原形。
如：He insisted that we (should) do our homework right now.
The doctor required that she (should) stay in bed for a few days.
She suggested that we (should) work out a questionnaire before doing a survey.

3、I would rather (that)…+一般过去时，表示“我宁愿/宁可”的意思，要注意的一点是，如果后面从句的主语是人称单数I而动词又是Be动词的话，后面接的是were而不是was.
如：I’d rather I were not here now.
I’d rather you did not tell him what had happened right now.

4、as if/as though, 或even if/even though这两组词汇考生用的频率还算比较高，但是时态会出现比较大的问题。当后面跟的从句发生在过去，那么谓语动词是使用过去完成时（had＋过去分词）。而后面跟的从句表示现在的状态，那么谓语动词用一般过去式（be用were）。当后面跟的从句表达将来的某个时间，那么谓语动词用过去将来时（would+动词原形）或者使用情态动词should / could + 动词原形。
如：
He is proficient at swimming as if he had learned swimming before.
He speaks French so fluently as if he were a Frenchman.
Even though he were here, he would be unwilling to help you.

5、“wish+宾语从句”这个结构一般在雅思作文中不太出现，因为它往往表达的是难以实现的愿望。同样的，对过去发生的表示愿望，谓语动词用过去完成时（had+过去分词或者could + have + 过去分词）。对于现在，谓语动词用一般过去式。对于将来，谓语动词用一般将来时（would (could)+动词原形）。
如：I wish you could help me.
I wish it were spring all the year round.
而在雅思写作中相比wish，hope可能用的比较多，它一般表示的是可以实现的愿望。考生们要注意其中的区别。
