When new types of computers appear on the market, the prices of old computers may ________.


  1. A.
    go up
  2. B.
    fall down
  3. C.
    come down
  4. D.
    rise
C
解析:
go up和rise表示“上升、上漲”;
fall down 表示“跌倒、垮下、失敗”;
come down表示“下跌、下降”。從一般的市場(chǎng)規(guī)律看,新型號(hào)計(jì)算機(jī)上市后,老電腦的價(jià)格會(huì)下降。因此,本題應(yīng)選擇C。
