【重点提示】
语法填空题并列句和状语从句考法
1.完整的句子中, 如果两个单词或短语并列, 要填并列连词;
2.若两个句子(两个主谓结构)之间没有句号或分号, 也没有连词, 空格处必定填连词;
3.牢记特殊句式中连词的运用;
4.全面掌握九大状语从句的连接词, 熟悉它们的用法;
5.准确判断主从句的逻辑关系, 同时要注意区分易混词。
并列句和状语从句在写作中都是经常用到的语法项目,尤其是状语从句的使用,经常可以为主要事件提
供更多的细节支撑,让写作饱满、丰厚起来,如2023年新高考Ⅰ卷的书面表达:
I promised that I would live up to his expectation and never stop writing in English though it was my second
language.我保证我不会辜负他的期望,尽管英语是我的第二语言,但我永远不会停止用英语写作。

尽致地表现出来。

里主句简化成了not，故选C。
【点睛】连词if和unless的用法
由引导词if或unless引导的状语从句叫条件状语从句。条件状语从句用来说明主句动作发生的条件，即某一件事情（从句中的动作）实现之后，其他事情（主句中的动作）方能发生。
if是“如果，假如”的意思。
1、 if引导的条件状语从句，既可放在主句之前也可放在主句之后。当从句置于主句之前时，常用逗号
与主句隔开。例如：You will catch the bus if you get up early.
=If you get up early，you will catch the bus.
如果你早起的话，就能赶上公共汽车。
2、时态
（1）若主句是一般将来时，if引导的从句用一般现在时
If it rains tomorrow，I'll stay at home.如果明天下雨，我将呆在家里
（2）如果主句是祈使句或含情态动词can，may，must等时，从句也用一般现在时。
例如：You must see the doctor if you are ill.如果你生病了，你必须去看医生。
If you want to go skating，wear warm clothes.如果你想去滑冰，穿上暖和的衣服。
3、主句不能用be going to表示将来，只能用wil1.
unless 也可引导条件状语从句，意思是“如果不；除非”，相当于...not...
We'll go for a picnic if it doesn't rain this Sunday
=We'll go for a picnic unless it rains this Sunday.
62. C
【解析】考查状语从句的省略。句意：众所周知，如果不小心处理，污染会越来越严重。根据句意可知，
此句是条件状语从句，主从句的主语都是the pollution。the pollution与deal with是动宾关系，故用被动语
态，从句的结构应是：if the pollution is not carefully dealt with。当主从句主语一致的时候，从句的主语可
以省略，省略原则是当从句谓语中包含be动词时，可以省略从句主语和be动词，保留be之后的部分，
故填if not carefully dealt with，故选C。
63. B
【解析】考查时间状语从句和从属连词。句意：他还没来得及冲出去，屋顶就塌了。A. until直到；B.
before在……以前；C. when当……时；D. since自……以来。分析句子可知，句子为时间状语从句，空格
处单词引导从句，根据句意可知，在他冲出去以前，屋顶就塌了，故应用“before”引导从句，意为
“在……以前”；until引导从句时，主句谓语应为延续性动词，“fell”是非延续性动词，故排除；when
引导从句时，主句为一般过去时，从句应用过去进行时，故排除；since引导从句时，主句一般用完成时，
故排除。故选B项。
64. B
【解析】本特纳的含义是哈利波特这本书如此有趣以致于所有的孩子都喜欢看，such ……that可以表示如
此……以致的意思，故本题选B。65. A
【解析】考查定语从句和状语从句。句意：经理对我所做的一切都很满意，以至于她给我升了职。分析
句子可知，在第一个空中，________ I had done是一个定语从句，先行词是all，先行词在定语从句中充当
had done的宾语，因此只能用关系代词that(what不能引导定语从句)；在第二个空中，是短语so...that...
“如此……以至于……”，that引导结果状语从句。故选A项。
66. B
【解析】
67. A

用作介词。故选B。
