阅读短文，用方框中所给单词或短语填空，使短文完整、正确。
although； as soon as； unless； so； before
In ancient times, there was an old man who lived on planting rice. He thought his crops (庄稼) grew more slowly than those of others. This caused him 1 worried and nervous that he decided to help the crops grow taller by pulling them up. 2 he felt tired after doing so much work all day, he went home happily. The man told his son what he did on the farm 3 he arrived home. His son felt strange and surprised so he went to the farm as quickly as possible. Finally, his son found all the crops were dead.
I believe everyone thinks the old man is silly. As we all know, plants won’t grow well 4 they develop in their own rules of growth. It is also the same for the development of other things. 5 we get a good result, try to be patient (有耐心的) and follow the rules of things. In this way, you can probably get what you want.
参考答案
一、
1．C
【详解】句意：除非你快点，否则我想你会错过这趟火车。
考查连词词义辨析。if如果，引导条件状语从句；and和，而，表示并列关系；unless除非，引导条件状语从句；when当......时，引导时间状语从句。根据题干“I think you′ll miss the train”我想你将会错过这趟火车，“you hurry up”你快点。可知用unless符合句意。故选C。
2．D
【详解】句意：——我们必须在六点前离开图书馆吗？——不，它周末全天都开。你可以待在那儿直到你想离开。
考查连词。if如果；unless除非；since自……以来；until直到……为止。根据“You can stay there ... you want to leave.”可知，是直到……为止。故选D。
3．B
【详解】句意：学生可能会很快忘记他们所学的东西，除非他们更经常地使用它。
考查从属连词词义辨析。if如果；unless除非，引导条件状语从句；although尽管，引导让步状语从句；because因为，引导原因状语从句。根据“Students may forget what they learn quickly”可知，此处应该表达除非他们更经常地使用它，unless“除非”。故选B。
4．A
【详解】句意：Sarah一看到老人躺在街上就拨打了120。
考查状语从句用法。as soon as一……就……；as long as只要；so that以便于；even if尽管。根据“Sarah called 120...she saw the old man lying on the street.”可知，需as soon as来引导时间状语从句，表达一看到老人躺在街上就拨打了120。故选A。
5．D
【详解】句意：每个人都应该做些什么来保护我们的地球，这样我们才能有一个更美好的世界生活。
考查连词辨析。as long as只要；as soon as一……就；even though即使；so that以便于。根据句意，“protect our earth”的目的是“have a better world to live in”，因此用so that引导目的状语从句。故选D。
6．C
【详解】句意：北京之行如此精彩以至于我想有一天再去一次。
考查状语从句用法。such...that如此……以至于，such后修饰名词；too...to...太……而不能……；so...that...如此……以至于……，so后跟形容词或副词；enough...to..足够……去做……。根据“...I would like to visit it again some day.”可知，第二个空需that，故排除选项B和D。wonderful为形容词，需so。故需so...that...来引导结果状语从句。故选C。
7．B
【详解】句意：杰克一完成作业就会和我们一起打篮球。
考查动词时态。join加入；finish完成。根据“as soon as”可知，as soon as引导的从句遵循“主将从现”原则，主句用一般将来时，结构为will do；从句用一般现在时，且he为第三人称单数，谓语动词用三单形式。故选B。
8．B
【详解】句意：除非你一遍又一遍地练习小提琴，否则你的技巧不会提高。
考查连词。since自从；unless除非；if如果；until直到。结合句意，你的技巧不会提高，应是在你没有反复练习的条件下，因此用连词unless引导条件状语从句，故选B。
9．C
【详解】句意：——你好，你是Molly吗？——不是。她不在家。她一回来，我就让她给你回电话。
考查连词辨析。so that为了；as long as只要；as soon as一……就……；even though即使。根据“I’ll tell her to call you back ... she comes back.”可知，是指她一回来，我就让她给你回电话，用as soon as引导时间状语从句。故选C。
10．A
【详解】句意：丽莎是一个非常好的女孩，我们都想帮助她。
考查短语辨析。such ... that ... 如此……以至于……；too ... to ... 太……而不能……；so ... that ... 如此……以至于……；very ... that ... 错误搭配。根据“we all want to help her”可知这里是结果状语从句，排除B；再由“a nice girl”可知用such修饰名词性短语，排除C。此处用such ... that ...引导结果状语从句。故选A。
11．D
【详解】句意：除非明天下雨，否则我们就会去广场看升旗仪式。
考查连词辨析。when当……时；if如果；since自从；unless除非。根据句意可知，去看升旗仪式的前提条件是明天不下雨，应用unless，相当于if...not。故选D。
12．B
【详解】句意：夏天，除非我们把食物放进冰箱里，否则食物很快就会变坏。A. if如果；B. unless除非；C. as soon as一……就；D. while正当……的时候。根据生活常识，在夏天只有放在冰箱里的食物才能保证不变质，unless除非，如果不，相当于if not，引导条件状语从句，故答案为B。
13．C
【详解】句意：她听到这消息激动得一句话也说不出来。
考查副词辨析。very非常；such如此；so如此。根据“that she couldn’t say a word”可知，是so/such...that...引导的结果状语从句，结合“excited”，是形容词，因此用so，故选C。
14．A

16．B
【详解】句意：一到凌晨12点，年轻人就都大喊着“新年快乐”。
考查连词辨析。after在……之后；as soon as一……就……；if如果；though虽然，根据主句“The young men all shouted ‘Happy New Year’”和从句“it was twelve o’clock”是紧接着发生的两个短动作，所以用as soon as引导的时间状语从句，表示“一到凌晨12点，年轻人就都大喊着‘新年快乐’”，故选B。
17．C
【详解】句意：她说，除非生意好转，否则她将不得不关闭餐厅。
考查从属连词。if 如果；after 在……之后；unless 除非；when 当……时候。根据 business improves和she'll have to close the restaurant可知“生意好转”与“她将不得不关闭餐厅。”是条件关系，应是“除非”。故选C。
18．C
