G) limited O) valuable H) local [br] 【C7】

选项

答案 M

解析 名词辨析题。该空位于hotel之后,而且与airline tickets、cars and homes构成主语,因此应填入名词。该句意为,很快,购买机票、______旅馆,甚至购买汽车和房子都可以在网上进行。结合日常生活,我们知道在网上可以预订宾馆房间,故空格处应填M)reservations“预订”。此外,根据and前后平行结构,大胆猜测空格处应填入复数名词,故排除剩余备选名词中的C)conservation和H)local,此外C)conservation易与M)reservations混淆,conservation来自于动词conserve,意为“保护”,没有“预留、预订”的含义,而J)occupations不能与hotel搭配,故均排除。
