Some place names in the USA are ____ to promounce and to spell because they are of Indian origin.
A.both difficult B.either difficult C.difficult both D.difficult either
答
选A.翻译为：由于有些地区起源于印度的缘故,它们的名称在美国都很难发音和拼写.
both意为“两者都”,与复数连用,常跟于some后,固定短语有both…and；either意为“两者都不是”,固定短语有either…or.做为形容词的前缀,both放于difficult前.
