四六级考试

【单选题】 With his poor English, he even cannot get his ideas across, ______ exert any essential effect on others.
A．let alone
B．that's to say
C．not to speak
D．not to say

网考网参考答案：A
网考网解析：
关联词辨析。选项[A]let alone意思为“更不必说”；选项[B]that is to say意为“也就是说”。没有选项[C]not to speak这种说法，而not to speak of可以表示“(更)不用说，当然”；选项[D]not to say意思是“虽说不上”，不合乎题意。 查看试题解析出处>>
