同学,我可以狠肯定狠负责地说,正确答案一定是B.
看到题目的第一反应就是选B.可是你说答案选A,我总觉得怎么可能呢?于是我又上网查了好多资料,仔细推敲这两个词的区别.最后我更加坚定,选B!
下面给出分析材料,楼主卟信可以自己推敲下 到底哪个才是最佳选择.
【PS：下面那么多,其实都是为了更好地帮助你了解这两个词的用法.但是要解答你的这个问题,最最关键的地方,在于倒数第二个例句.即 mostly 还常与介宾结构连用】
【详细分析】：
这两个词都可以作副词,但意义和用法不同.
【一】almost的用法通常是以下两种：
1.修饰动词(位置一般在实意动词之前或be动词之后),表(某个动作)即将完成.例如：
a) I have almost finished my introduction to the book.(接v.)
b) It is almost three o’clock.(接be动词)
2.修饰形容词、副词、数词和名词等,表程度.例如：
c) I agreed with almost every word of it.(接adj.)
d) It was almost midnight when we heard the good news over the radio.(接n.)
almost 在修饰动词、形容词、副词、数词和名词等时与nearly常可换用,但和 no,none,nothing,never等连用时除外.例如：
e) She said almost nothing.
【二】mostly虽可译为“几乎”,但常意为“主要地”、“多半”、“绝大多数地”或“在多数情况下”等等.除可接动词、名词、副词、形容词外,还常与介宾结构和句子连用.例如：
f) He mostly lent me a hand when I was in trouble.(接v.)
g) They were mostly middle-aged decent folk.(接n.)
h) The medicine was mostly augar and water.(接n.)
i) Our weather has been mostly warm.(接adj.)
j) She is mostly out on Sundays.(接adv.)
k) She uses her car mostly for going to the shops.(接介宾结构)
l) He enjoys a cigarette sometimes,but mostly he smokes a pipe.(接从句)
从以上例句可看出:almost侧重表程度或表某动作即将完成,mostly侧重表比例关系.与动词搭配时如例a)中almost表finish这个动作快要完结,而例f)中mostly则表示lent me a hand所发生的频率较高.
