三个英语基础问题,燃眉之急!
①The country has already sent up three unmanned spacecraft,the most recent ( has been launched ) at the end of last March .
括号里面的( has been launched ) 要改成【having been launched】才对.为什么呢?
②Many young people in the West are expected to leave what could be life's most important decision-marriage-almost entirely up to luck .
晕晕的,我看了其他翻译,好像都没有把[ leave ]这个词翻译出来.顺便解释下leave在这句话的意思、作用.
③It helps us understand the world better if we [ knew ] a little geography .
这里的 [ knew ] 答案说需要改成[know],为什么呢?虚拟语气不是要用过去时么?

1、这是非谓语结构,前面已有动词了,后面当然用非谓语啰
2、这里是‘交给,留给’的意思.就是西方很多人把人生中最重要的决定-有关婚姻的决定-交给命运来决定.
3、这里是条件状语,不是虚拟语气
若果不明白你再问吧,

1,过去分词时,用现在进行时
2,???
3,nonono,这里是一般现在时,多培养语感
