The copy machine has not been repaired because the part it requires ______
out of stocks.
A) is B) are C) to be D) to have been
這題是A
我想問的是 because 後面 the part it requires 是什麼意思
require 不是動詞了嗎 加上is 不就有兩個動詞了嗎
This shirt should be cleaned with neutral detergents and dried quickly to
limit browning as ____ by the manufacturer.
A) recommendation B) recommending C) recommended D) recommend
這題是C 我只是想確認這裡的as後面代表的意思是否是 如同製造商推薦的意思
謝謝

1.需要的零件缺貨2.如同製造商建議

1. require需要受詞(查字典就有了)because the part [(that/which) it requires](關係子句)is out of stock(單數)此處的關代是'requires'的受詞http://www.ldoceonline.com/dictionary/stock_1-> 1 ... 藍色字部份 這是固定用法，不能亂改成stocks
