文法講座 022：使役動詞
http://www.learnerhall.org/2012/11/blog-post_19.html
但這四個使役動詞意思上略有差別：
1️⃣ let：讓某人做他想做的事。
2️⃣ make：強迫某人 / 叫某人做事(尤其是做他不想做的事)。且也可用 make + N + adj的寫法，如：這個壞消息讓我很傷心。This bad news makes me sad.
3️⃣ have：賦予某人責任 / 叫某人做事。
4️⃣ get：說服 / 叫某人做事。
▍使役動詞的使用方式
Ⓐ Mom thinks computer games are a waste of time, so she won’t let us to play them.
Ⓑ With a little smooth talk, she got her husband mop the floor for her.
Ⓒ That she won the first prize made everyone surprised.
Ⓓ The teacher made her students use a dictionary while they were taking the English test.
使役動詞 let 後面加受詞 us，因受詞可執行 play computer games 這動作，故應搭配 play (V原)，而非 to V原。
Ⓑ 選項：好言拜託後，她說動丈夫幫她擦了地板。
使役動詞 got 加受詞 her husband，因受詞能執行 mop the floor 這動作，故應搭配 to mop (to V原)，而非V原。
Ⓒ 選項：她得第一名這件事讓每個人都很驚訝。
使役動詞 made 的確切意思為強迫某人做他不想做的事。但考英文時可用字典，絕不會是學生們不想做的事，因此建議將使役動詞 made 改成使役動詞let，因 let 意指「讓某人做他想做的事」。
答案：Ⓒ
Let + O + be p.p. (過去分詞) 主要用在「祈使句的被動語態」，使用頻率不高，建議直接用「祈使句」表達，或將 let 換成 make/ get / have，這樣的用法較符合習慣用語。
例：請修正你的錯誤。
✓ 祈使句：Please correct your mistakes.
✓ let 被動：Let your mistakes be corrected.
✓ 使役動詞：Please have your mistakes corrected.
例：我不想去補習，但我媽叫我去。
✓ I don’t want to go to cram school, but my mom makes me go.
✓ I don’t want to go to cram school, but my mom has me go.
✓ I don’t want to go to cram school, but my mom gets me to go.
✓ I don’t want to go to cram school, but my mom has me go.
✓ I don’t want to go to cram school, but my mom gets me to go.
使役動詞 makes / has 加受詞 me，因受詞能執行 go to cram school 這動作，故搭配 go (V原)。使役動詞 gets 加受詞 me，因受詞能執行 go to cram school 這動作，故搭配 to go (to V原)。
例：他叫兩個護士照顧生病的男孩。
例：他叫兩個護士照顧生病的男孩。
✓ He had two nurses take care of this sick boy.
✓ He got two nurses to take care of the sick boy.
= 他讓生病的男孩被兩個護士照顧。
✓ He had the sick boy taken care of by two nurses.
✓ He had the sick boy taken care of by two nurses.
➤第一句，使役動詞 had 加受詞 two nurses，因受詞可執行 take care of 這動作，故搭配 take (V原)。使役動詞 got 加受詞 two nurses，因受詞可執行 take care of 這動作，故搭配 to take (to V原)。
➤第二句，使役動詞 had 加受詞 the sick boy，因受詞無法執行 take care of 這動作，故搭配 taken (p.p.)。
