if如果;though虽然;because因为;until直到。根据“Tom didn’t let Ben paint at first... he wanted to make it seem valuable.”可知,前后句之间存在因果关系,后句“他想让它显得很有价值”是前句“不让本粉刷”的原因,所以用because引导原因状语从句。

二、完成句子(本大题共10小题,每小题4分,共40分)
31.He will be free tomorrow. He will go shopping.(合并为条件状语从句)
________________________________________________________________________
【答案】If he is free tomorrow, he will go shopping./He will go shopping if he is free tomorrow.
【详解】句意:他明天有空。他将要去购物。前句“明天有空”是后句“去购物”的条件,因此使用连词if“如果”引导条件状语从句。遵循“主将从现”原则。即在if引导的条件状语从句中,如果主句是一般将来时,从句需用一般现在时来表示将来。将从句中的“will be” 改为“is”,置于if之后,另一句作为主句,首字母大写,if可前置也可以后置。
32.Without your help, I can’t finish the task on time. (if 引导条件状语从句)
_______________________________________________________________
【答案】If you don’t help me, I can’t finish the task on time.
【详解】原句句意:没有你的帮助,我无法按时完成这项任务。“Without your help” 是一个介词短语,表示“如果没有你的帮助”,是一个假设条件,“I can’t finish the task on time”是这个条件下的结果。题干要求改为if 引导条件状语从句,也就是将“Without your help”转换为if条件句。原句can’t是一般现在时,表示一种普遍事实或当前情况,因此改写后的句子也使用一般现在时态,所以将“Without your help”改为“If you don’t help me” ,后半部分保留原句即可。故填If you don’t help me, I can’t finish the task on time.
33.I will buy books. I have enough money. (用 if 连成一句)
_________________________________________________
【答案】I will buy books if I have enough money.
【详解】句意:我会买书。 我有足够的钱。本题要求用if引导条件状语从句合并句子,遵循“主将从现”原则,从句“I have enough money”用一般现在时,主句“I will buy books”用一般将来时。故连成句子为I will buy books if I have enough money。
34.No rain, and we will go for a picnic. (if条件状语从句)
_______________________________________________________________
【答案】If it doesn’t rain, we will go for a picnic.
【详解】句意:如果不下雨,我们就去野餐。原句“No rain, and...”是“祈使句/名词短语+and+陈述句”的结构,表示假设关系。改写时,“if”引导的从句需用一般现在时表将来(主将从现原则),主语用代词“it”指代天气,谓语动词用否定形式“doesn’t rain”;主句保持一般将来时“we will go for a picnic”不变。
35.We can donate money when we finish collecting. (改成if条件)
_________________________________________________
【答案】We can donate money if we finish collecting.
【详解】句意:当我们完成收集时,我们可以捐钱。原句中“when”引导的是时间状语从句,表示“当……时候”。要改成if条件句,只需将“when”替换为“if”,意思变为“如果我们完成收集,我们可以捐钱”,句子时态等其他部分保持不变。
36.如果你生病了,最好去看医生。
If you ________ ________, you’d better ________ ________ ________.
【答案】 are/fall ill see a doctor
【详解】原句中“生病”和“看医生”是关键词。表示“生病”的短语是be/fall ill,if引导的条件状语从句,从句需使用一般现在时,主语you为第二人称,所以谓语用are/fall;表示“看医生”的短语是see a doctor,“had better do sth.”表示“最好做某事”,see保持动词原形不变。
37.I like managing money. It helps me develop a sense of responsibility.(用because合并句子)
I like managing money ________ ________ ________ me develop a sense of responsibility.
【答案】 because it helps
【详解】句意:我喜欢理财,因为它帮助我培养责任感。because引导原因状语从句,承接后面完整分句,主语it指代managing money,谓语动词用helps保持原句时态不变。
38.He was ill. He didn’t go to school. (合并为含 because 的复合句)
He didn’t go to school ________ ________ ________ ill.
【答案】 because he was
【详解】句意:他病了。他没去上学。合并为含because的复合句,即because连接原因状语从句,主句是一般过去时,从句也是一般过去时,“because”后接从句“he was ill.”。故填because;he;was。
39.既然这个项目很有价值,为何不尽快开展呢?
Why don’t you carry out the project ________ ________ ________ ________ ________ it is of great value?
【答案】 as soon as possible since
【详解】原句中“尽快”“既然”是关键词,表示“尽快”的短语是as soon as possible,句子作状语;表示“既然”的连词是since,引导原因状语从句。
40.It rained heavily. We had to stay at home.(用since合并)
________ ________ ________ heavily, we had to stay at home.
【答案】 Since it rained
