正确答案: D
解析:
设鞋子的单价为x,靴子的单价为y,则22x+16y=650,8x+32y=760,故x=15,y=20,两者相差$5,故本题选B项。

  • 第1题:

    In some pairs of antonyms, the marked terms cover the meaning of the unmarked.( )

    此题为判断题(对,错)。


    正确答案:错误

  • 第2题:

    I had worn out two pairs of boots on the walking tour , I needed a third one (疑问:此处的a third 能不能换成the third )谢谢


    不能 the就变成特指了 这里是随便的第三双 而没有特指的意思

    不可以的。因为这句话的意思是 我需要另外一双鞋。
    而如果你换成 the 的话,那就是第三双了。但是,你要知道。这样的意思压根就不成立。

    在现代书面英语中,a 的形式用于以辅音开头的单词前, 但这个词可能被拼成(a frog,a university,a euphemism )。 an 的形式用于以元音开头的词前( an orange,an hour )。 有一度an 用于以辅音开头但拼写形式为元音的单词前的形式也被认可( an one,an united appeal ), 但这种用法现在已被废弃了。an 曾是用于第一个音节不重读,且以 h 为开头的单词前的一种常见变体形式; 所以18世纪的作家既可用a historical 也可用 an historical, 但不可用 a history 也不可用 an history。 当h 在这样一些单词,如 historical 和 heroic 中作为起首字母而又不发音时,这种用法在语音学上是合理的。 这种用法在19世纪末的高雅用语中已基本废弃了。1926年时H.W.福勒还认为an 继续在这些单词前使用太具学究气了。 现在这种用法主要在historical 前时还保存使用; 在an hysterectomy 或 an hereditary trait 之前则极为少见。 在正式的书面语中,象an historic opportunity 这种用法也不失为一种装饰 。

      2. 指谈话双方都知道的人或事物。 Where is the teacher? Open the door.

    A.boot and bought

    B.deep and dog

    C.either and neither
