英語四級(jí)閱讀關(guān)鍵句：251. If Sept. 11 had never happened,

251. If Sept. 11 had never happened, the airport workers would not have been arrested and could have gone on quietly living in America, probably indefinitely.

譯文

如果9·11事件從未發(fā)生，機(jī)場工人就不會(huì)被逮捕，還會(huì)繼續(xù)安靜并有可能永久地生活在美國。

點(diǎn)睛

本句的主干是workers would not have been arrested and could have gone on。

本句采用了虛擬語氣，通過if引導(dǎo)的條件狀語從句中的過去完成時(shí)態(tài)，以及主句的將來完成時(shí)可知，本句是對(duì)過去事實(shí)的虛擬。probably indefinitely充當(dāng)could have gone on的狀語。

go on此處的意思是“繼續(xù)，持續(xù)”，后接doing sth.表示持續(xù)的動(dòng)作。如：

You can't go on drinking so much. 你不能再喝這么多酒了。

考點(diǎn)歸納

go on是個(gè)常見的短語，其用法有很多：

意為“開始運(yùn)行，開始工作”。如：

The lights went on automatically. 燈自動(dòng)亮了。

意為“流逝，過去”。如：

As time went on, he became more and more talkative. 隨著時(shí)間的推移，他變得越來越健談。

意為“發(fā)生”。如：

What's going on in your office? 你辦公室里發(fā)生什么事了？

意為“接著做（另一件事）”。如：

Let's go on to the next item on the agenda. 我們繼續(xù)議程的下一項(xiàng)吧。
