答案与题解:
1. B 空格后是一种装置,用它来改变火灾时找不到出口的危险境况。表达“用……装置”这层意思就要用介词 with。其他几项均不符合句子的意思。
2. A Sound Alert是一家公司的名字, a company是 Sound Alert的同位语,从句意判断,应选择 run by,意为“由……经营的”。其他的选项虽然说法正确,但都与句意不符。
3. C 从文章的标题,以及文章内容和本句后面部分 resource center for the blind,可以推断这里昀好的选择就是 C。
4. D 因为这种警告装置已在上文中提到:第一段中的 directional sound alarms,第二段中的 installing the alarms in a residential home…,所以,这里的 alarms是特指,要用定冠词。选项 C是错误的,因为它是单数形式。
5. B 句子的前半句有 a wide range of frequencies,发出来的应该是 sound,而不是令人烦躁的 noise。用 music或 bell都有些突然,与上下文的意思不连贯。
6. D 文章一直在讨论警报器、声音和波长,所以首先排除选项 A;从上下文的意思看,不可能是选项 B和 C,因为警报器的制造,就是为了让失明的人听到。
7. C 选择 A、B、D均不能构成语义连贯的句子,而且语法上也有问题。选项 C能使句子结构成为 “It is … that”的强调句型。
8. B 从所给的选项可以看出,这里要表达的意思是“烟火弥漫的房间”。有了这个理解,现在要做的就是选择正确的表达形式。 A是“烟熏的”, D是“使……烟火弥漫的”,所以意思不对, C填入后就出现 filled with smoke room,不符合语法。只有 B是正确的选项。
9. C 这里显然是“ It takes somebody + time +动词不定式”的句型,但选择什么时态是关键。从上句看,应选择一般过去时,因为整个段落是对一次试验的描写,而且上而一句也使用了一般过去时。
10. C后半句的 one指上半句中的 a sound alarm。该句上半句和下半句由 but连接,表示相反的意思,从后半句的 with可以看出,两个相对比的事物是: the door without a sound alarm和 the door with a sound alarm。所以选择 C。
11. A 选项 B、C和 D显然是错误的,因为词义不符。只有选项 A是答案。句子的意思是, Withington在她的.大学里研究大脑如何处理声音。
12. D 句子中的 more … than表示该句是对两样事物的对比。 than后面是 the source of a narrow band,这里的 narrow和前半句的 wide形成反比,从上下文中可以看出, the source of a narrow band of (frequencies)是和 the source of a wide band of frequencies形成对比。
13. D 这个句子有主语 alarms,有谓语 have been installed,这里应填入动词的分词形式。 be based on是常用的搭配,所以,应选择动词的过去分词形式。选项 A的 basis是名词,明显是错的。
14. A 根据上半句中的 rising or falling frequencies,这里应填入 or,与上半句表达的意思相一致。音频升高表示上楼,音频降低表示下楼。
15. A 首先确定主语 They指的是第一句中的主语 The alarms,后半句说这种设备得到大笔资助。根据上文内容,我们知道资助的目的是开发这种 alarms,所以应该选择 developed。
