為何不答ａ和ｂ？

2.We failed to tell you that your records were deleted .
當中的failed做何翻譯

謝謝

Answer 1

1. 因為主詞必須是名詞相等語 (例如: 名詞, 代名詞, 動名詞,
名詞片語, 名詞子句等)才可當主詞喲! 而 fail 的名詞形式
就是 failure 喔!
Failure to examine the capabilities of the computer carefully
has cost us a lot of time and money.

2. failed to: 不能 ... ; 無法 ...
We failed to tell you that your records were deleted.
我們無法告訴你, 你的記錄以被刪除了.

Answer 2

1. ( ____ to examine the capabilities of the computer carefully)
" has cost" us a lot of time and money.

我括號部分是主詞 (S),
所以fail要用其名詞 failure.
句子的 "has cost " 完成式動詞.

★ 重要文法: Failure to (未能) .... + 單數動詞

2. We failed to tell you that your records were deleted .
當中的failed做何翻譯:

★ fail to V (未能...)

例如: We failed to tell you that your records were deleted .
(我們未能告訴你你的紀錄已被刪除了)
