答案與題解:
1. B 空格后是一種裝置,用它來改變火災(zāi)時找不到出口的危險境況。表達“用……裝置”這層意思就要用介詞 with。其他幾項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的同位語,從句意判斷,應(yīng)選擇 run by,意為“由……經(jīng)營的”。其他的選項雖然說法正確,但都與句意不符。
3. C 從文章的標題,以及文章內(nèi)容和本句后面部分 resource center for the blind,可以推斷這里昀好的選擇就是 C。
4. D 因為這種警告裝置已在上文中提到:第一段中的 directional sound alarms,第二段中的 installing the alarms in a residential home…,所以,這里的 alarms是特指,要用定冠詞。選項 C是錯誤的,因為它是單數(shù)形式。
5. B 句子的前半句有 a wide range of frequencies,發(fā)出來的應(yīng)該是 sound,而不是令人煩躁的 noise。用 music或 bell都有些突然,與上下文的意思不連貫。
6. D 文章一直在討論警報器、聲音和波長,所以首先排除選項 A;從上下文的意思看,不可能是選項 B和 C,因為警報器的制造,就是為了讓失明的人聽到。
7. C 選擇 A、B、D均不能構(gòu)成語義連貫的句子,而且語法上也有問題。選項 C能使句子結(jié)構(gòu)成為 “It is … that”的強調(diào)句型。
8. B 從所給的選項可以看出,這里要表達的意思是“煙火彌漫的房間”。有了這個理解,現(xiàn)在要做的就是選擇正確的表達形式。 A是“煙熏的”, D是“使……煙火彌漫的”,所以意思不對, C填入后就出現(xiàn) filled with smoke room,不符合語法。只有 B是正確的選項。
9. C 這里顯然是“ It takes somebody + time +動詞不定式”的句型,但選擇什么時態(tài)是關(guān)鍵。從上句看,應(yīng)選擇一般過去時,因為整個段落是對一次試驗的描寫,而且上而一句也使用了一般過去時。
10. C后半句的 one指上半句中的 a sound alarm。該句上半句和下半句由 but連接,表示相反的意思,從后半句的 with可以看出,兩個相對比的事物是: the door without a sound alarm和 the door with a sound alarm。所以選擇 C。
11. A 選項 B、C和 D顯然是錯誤的,因為詞義不符。只有選項 A是答案。句子的意思是, Withington在她的.大學(xué)里研究大腦如何處理聲音。
12. D 句子中的 more … than表示該句是對兩樣事物的對比。 than后面是 the source of a narrow band,這里的 narrow和前半句的 wide形成反比,從上下文中可以看出, the source of a narrow band of (frequencies)是和 the source of a wide band of frequencies形成對比。
13. D 這個句子有主語 alarms,有謂語 have been installed,這里應(yīng)填入動詞的分詞形式。 be based on是常用的搭配,所以,應(yīng)選擇動詞的過去分詞形式。選項 A的 basis是名詞,明顯是錯的。
14. A 根據(jù)上半句中的 rising or falling frequencies,這里應(yīng)填入 or,與上半句表達的意思相一致。音頻升高表示上樓,音頻降低表示下樓。
15. A 首先確定主語 They指的是第一句中的主語 The alarms,后半句說這種設(shè)備得到大筆資助。根據(jù)上文內(nèi)容,我們知道資助的目的是開發(fā)這種 alarms,所以應(yīng)該選擇 developed。
