2: The word "gizmos" (line 1, paragraph 2)most probably means ________.
正確答案C：devices
原文定位：As a result, the modern world isincreasingly populated by intelligent gizmos whose presence we barely noticebut whose universal existence has removed much human labor.
解題要點：從題型來看, 這屬于典型的詞匯題, 而詞匯題的做題關(guān)鍵則是在原文的上下文中找出相應(yīng)的近義詞, 同義詞和反義詞之類, 也可以使同義表達醫(yī),學(xué)全,在線.搜集.整理gydjdsj.org.cn.從后面定語從句來看，重點是remove human labor. 再從后面的幾個例子中，factory,banking, subway train幾個東西都是工具，得出答案。

答題要點：同義替換, with human intervention替換了文中with less human supervision.
比其他一些題目更難的地方在于, 這句話無論是原文還是正確選項都有個前提, 所以必須考慮進來, 如果不考慮前提,很有可能出現(xiàn)斷章取義, 導(dǎo)致錯選了A, make a fewdecision for themselves.
