单选题 ______ he's been learning English for no more than a year, he speaks it very well.
A．Assuming B．Considering
C．Supposing D．Now that

【正确答案】 B

【答案解析】[解析] considering在这里并不是现在分词，不能作分词短语分析，而是连词(有时作介词)，后面跟从句，表示“考虑到”，在句中起类似让步状语的作用，也就是说可以把它改写成一个让步状语从句，如：He leads a very active life, considering his age(=although he is old).
