大半

For much of his life he suffered from recurrent bouts of depression.

他的辈子反复发作抑郁症。

After a lot of umming and aahing, he finally said yes to the plan.

他吾了天，终于同意了项计划。

He got terribly drunk and was throwing up for most of the night.

他喝得烂醉,呕吐了。

These ideas held sway for most of the century.

些思想占配地位长个世纪。

This country is largely desert.

个国家都是沙漠。
