看到這一題,才知道以前都在混,這麼重要的解釋差異,這麼就沒給找出來
先講對的,
require that...V
require of ... that V(以上兩種都用在假設法)
require sb to do sth...
以上都是可以的
剩下就是 require of sb to do sth.這種用法到底可不可以的問題...
先看OG109 的解釋
Choices C, D, and E produce the ungrammatical construction requires of... employers to pay, in which of makes the phrase incorrect.
不講別的,OG這裡就是點出
requires of... employers to pay就是不行,沒得商量(注意這是主動)
回到181,解釋提到選B的三層概念
The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore, the logical subject of to survive and the logical complement of required should be made explicit. All three demands are met by B, the best choice.
1.原題主詞(such firms)如果沒有
of firms,such就找不到對象
2.看到不定詞to survive,就該想想logical subject是誰
3.看到required(注意,過去分詞),就得思考一下誰是logical complement
因此解答進一步闡述,補一個B,答案就對了
但我查了longman的字典,發覺有一個想法也可以討論看看
回到181題
(標準句型)
181.Because of the enormous research and development expenditures required
of firms to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.
原因子句還原後是這樣寫的
Because of the enormous research and development expenditures
that are required of firms to survive in the......是被動式喔,以中文思考就是"由於大量的研發用是公司生存所需要" 進一步說,就是被動式可允許are require of sb to do sth...
但若改為主動,直接寫成"because firms require the enormous research and development expenditures to survive....."of 變的沒法加,也沒必要加了
所以結論,109解釋的並沒錯,但合併181,我們有以下結論
"require of sb to do sth. "is unidiomatic
...(不可用於主動)。
但 "..... are required of firms to survive in the electronics industry"(就可以了),這裡的of可以理解為by
,(用於被動,就可以加of)
