1. There ought to be less anxiety over the perceived risk of mountain climbing than exists in the public mind today.
考察重点:动词时态与主谓一致
首先我们需要还原整个句子,climbing than the anxiety that exists in the public mind today. 抓住了还原部分的主语anxiety,明显是一个三单,且这句话是客观陈述,所以使用一般现在时exists。
2. The decision of our company was that we have everything prepared well by the end of this month.
重点:虚拟语气
是不是很好奇前面明明是was,后面却使用了动词原形而非had。其实这不是时态的考点,而是The decision is that_____这是一个表语从句,后面的动词应为should 动词原形,且should可以省略,所以后面此处应填(should) have。
By the time you get to Washington tomorrow, I shall have left for Chicago.
重点:by the time时态
by the time 后接时间状语从句的时候——主语使用一般现在时,从句使用将来完成时。记住这个用法,背例句就好了。
Helen has just arrived, and I didn’t know she was coming until last night.
重点:进行时表将来
我们先来分析句子成分,I(主语)didn’t know(谓语)…(宾语)。后半句其实是一个宾语从句,时态应当遵循主句,肯定是要跟着didn"t用过去时没跑了。但是为什么要用ing呢?首先,“海伦刚到,我昨晚才知道她今天将要来”意味着她今天的到来相比于昨天的知晓是一个将来的状态,而且因为come是瞬间动词,所以was coming可以表将来。
拓展:常见的瞬间动词:leave, close, buy, join, become, begin, fall, come, go, see, hear, kill等。
一般我们说:“I’m leaving.”肯定不是“我正在离开。”而是指“我要走了/我要离开了。”
Not being tall should not become a serious disadvantage in life and work.
重点:动名词作主语
动词要做主语的话,必须非谓语!!!谁要是把原形放上去我就弄谁!不是被动不表目的不是将来那不就用ing吗?但是,否定可咋整,是not being 还是being not?记住:not being/doing sth. 动名词作主语的否定形式记住就好了。
