until/so that/although引導的狀語從句考點梳理

王秀鳳

一、until的用法

until與延續性動詞連用時，動詞用肯定形式，表示“直到……為止”，指主句的動作一直持續到until后的動作發生為止;與短暫性動詞連用時，動詞須用否定形式，意為“直到……才……”，指主句的動作一直到until后的動作發生時才發生。

1. 作介詞，表示“直到……為止”。

I waited until 3：00， but he didn't come. 我一直等到3點，但他沒來。

—Jack didn't go to bed ___ 12 o'clock last night.

—That's why he was late for school this morning.

A. until B. for C. to D. at

【解析】 A。句意：——杰克昨晚直到十二點才睡。——這就是他今早遲到的原因。not... until為固定搭配，意為“直到……才”。

2. 作連詞，表示“直到……為止;在……以前;不到……（不）”。

① 用于肯定句中。

Please wait here until I come. 請在這里等到我來。

② 用于否定句中。

The noise of the street didn't stop until midnight. 街上的喧鬧聲一直到半夜才停止。

She didn't leave the school ___ she worked out this problem.

A. as long as B. until C. since D. while

【解析】 B。句意“直到解決了這個問題她才離開學校”。as long as只要（引導條件狀語從句）;until直到（引導時間狀語從句）;since自從（引導時間狀語從句）;while當……時候（引導時間狀語從句）。根據句意，故選B。

We didn't cut the cake ___ Amy made a wish.

A. because B. until C. if

【解析】 B。because因為，until直到，if如果。根據句意“直到艾米許了個愿，我們才切蛋糕”可知，其它選項語意不通。

Helen was very rude to me. I refuse to speak to her again ___ she says sorry.

A. until ? ? ? ? B. if

C. because ? ? ? D. since

【解析】 A。句意：海倫對我粗魯，我拒絕跟她再次說話，直到她向我道歉為止。until意為“直到……才”，符合句意。if意為“如果”;because意為“因為”;since意為“自從：既然”。故選A。

二、so that的用法

1. so that意為“目的是/為的是/以便”，引導目的狀語從句，從句中通常含情態動詞can， may， might等。

He got up very early so that he could catch the early bus. 他起床很早，為的是能趕上早班公共汽車。

We should take care of the earth ___ we can make a better world to live in.

A. so that ?B. until ?C. even if ?D. while

【解析】 A。句意：我們應該關愛地球，為了我們能創造一個更美好的世界。so that 為了; until 直到;even if 即使;while 當……時候;根據We should take care of the earth 和we can make a better world to live in之間的關系是表示目的，故選A。

2. so that引導目的狀語從句，當主句主語與從句主語一致時，可用“so as to / in order to+動詞原形”轉化為簡單句。

He got up early so that he could catch the early bus. 為了趕早班公交車他起床很早。

=He got up early in order to / so as to catch the early bus.

3. so that還可以與in order that互換。
