答案
Ⅰ.1.A　连词辨析。前句“工作日我总是早起”和后句“我担心上学会迟到”构成因果关系,后面表示原因,所以应用because引导原因状语从句。
2.B　3.A　4.C
5.D　句意:“我喜欢雨,　　　　它让我感觉到凉爽和放松。”“我也是。”句中“it makes me feel cool and relaxed”与“I like rain”构成逻辑上的因果关系,因此要用连词because表示原因。
6.A　because 引导的原因状语从句。because意为“因为”,引导原因状语从句,后接句子; because of意为“因为”,是介词短语,后接名词、代词或名词性短语; if意为“如果”,引导条件状语从句;so意为“所以”,引导结果状语从句。句意:他昨天没有去上学,因为他生病了。
7.A　句意:这两家公司决定一起工作,　　　　他们有共同的利益。because意为“因为”;so意为“因此”;but意为“但是”;before意为“在……之前”。分析句子结构可知,后面的“they had the same interest”是一个从句,是前面“两家公司想要一起工作”的原因,所以应用because引导原因状语从句。
8.B　句意:小男孩赢得了比赛因为他总是在空闲时间练习下国际象棋。so意为“因此”;because意为“因为”;but意为“但是”;when意为“当……时候”。横线后面“他总是在空闲时间练习下国际象棋”是横线前面“小男孩赢得比赛”的原因。
9.A　汉语习惯上说“因为……所以……”,然而英语中because不与so连用。句意:因为迈克生病了,所以他不能和我们一起去公园。
10.A
11.A　连词的用法。句意:天空更蓝了,因为我们已经采取行动来保护环境。because意为“因为”;before意为“在……以前”;until意为“直到”;unless意为“除非”。根据句意可知选A。
12.A　连词的用法。句意:“谢谢你告诉我这么多关于大自然的知识。”“别客气。如果你有更多的问题,随时来找我。”if意为“如果”;because意为“因为”;though意为“尽管”;unless意为“除非”。句中空白处应用if表示“如果”,是一种假设,
Ⅱ.13.because　14.Because　15.because of
16.because of　17.Because of
