是不是楼主打错横线了,答案应该是:
He works very hard so that he won't lose his job.
= He works hard (in order not to) lose his job.
= He works hard (so as not to)lose his job.
= He works hard (in order that he will) not lose his job.句中that可以省略
= He works hard (for fear that he should) lose his job.句中that可以省略,should也可以省略
= He works hard (lest he should) lose his job.句中should可以省略
