18、lisbestsportinspring.冠詞綜合練習(xí)參考答案C。解析：theWest（西方、西洋）是固定搭配；指類(lèi)似于的人或物時(shí)，專(zhuān)有名詞前用冠詞，而Shanghai又受oftheWest修飾，所以用the。C。解析：第一空an用于以元音音素開(kāi)頭的詞前；第二空泛指有英語(yǔ)知識(shí)的人。D。解析:不定冠詞a用于以輔音音素開(kāi)頭的詞前（指發(fā)音而不是字母），如:auniversity；而an用于以元音音素開(kāi)頭的詞前，如anuncle/anhonestman.D。解析：第一空是序數(shù)詞前用a表示“又一”；輔音字母n,f,h,l,m,n,r,s,x和元音字母a,e,i,o的讀音，均以元音開(kāi)頭，所以第二空填an。

19、C。解析：第一空是泛指用a,aheavypressure意為“一種很大的壓力”；當(dāng)whole修飾單數(shù)名詞表示“全（部的），整個(gè)的時(shí)，前面用ones或the,又如thewholeevening/truth整個(gè)晚上/全部真相。C。解析：and前后連接的是同一事物同一人同一概念時(shí)，其后的名詞前不用冠詞。D。解析：比較：putintoprison=坐牢；gototheprison=去監(jiān)獄。D。解析：“the+形容詞比較級(jí)+ofthetwo+名詞復(fù)數(shù)”結(jié)構(gòu)表示：兩者中較的一個(gè)。B。解析：infront。彳=在前面（指范圍之外）；inthefront。彳=在前部（指范圍之內(nèi)）。A。解析：inchargeo
