单选题
The ink had faded with time and so parts of the letter were illegible.
A. illiterate B. illegitimate C. inscrutable D. indecipherable
【正确答案】
D
【答案解析】[解析] illiterate意为“文盲的,无知的”,illegitimate意为“非法的,不合理的”,inscrmane 意为“不可测知的,神秘的”,indecipherable意为“不可破译的,模糊的,难易辨认的”。这 句话比较好理解,墨水随时间而退色,因而信的部分内容难以辨认。故正确答案为D。
