雅虎知識:The experiment is designed to test the new drug. is designed是及物動詞,但The building was designed by me. was designed (是不及物動詞)+介係詞+me, 如何解釋?

1. The experiment is designed to test the new drug.
2. The building was designed by me.

两句的動詞 "design" 都是及物動詞, 亦都用作被動語態 (passive voice).

1. "to test the new drug" 是副詞性質,修飾動詞 "design" 說明了設計的目的. 而動詞 "design" 在這種句義中一般用被動語態 (be + designed).

2. "by me" 用作表達被動語態中 動詞 (design) 的主詞 (I);
主動句是:  I designed the building.   (building 是 designed 的受詞)

例句以CAPITAL LETTERS 表示

望採納望點讚望最佳解答謝謝????

1.及物動詞 Vt. (Transitive verb)

及物動詞後面需要接受詞，而這類動詞又被分為『完全及物動詞』和『不完全及物動詞』。

a. 完全及物動詞(Complete transitive verb)

主詞 (Subject) + 動詞 (Verb) + 受詞 (Object)

THE EXPERIMENT (SUBJECT) IS DESIGNED TO TEST(VERB) THE NEW DRUG(OBJECT).

b. 不完全及物動詞 (Incomplete transitive verb)

動詞後面不只要有受詞，還需要有受詞補語，來表達動詞想要傳達的完整意思。

主詞 (Subject) + 動詞 (Verb) + 受詞 (Object) 受詞補語 (Object complement)

2.不及物動詞 Vi. (Intransitive verb)

不及物動詞後面不接受詞就可以表達完整的句意，但他們也被分為『完全不及物動詞』和『不完全不及物動詞』

a. 完全不及物動詞 (Complete intransitive verb)

即不需要受詞，也不需要補語。

主詞 (Subject) + 動詞 (Verb)

b. 不完全不及物動詞 (Incomplete intransitive verb)

不需要受詞，但需要補語才能表達動詞完整的意思。

主詞 (Subject) + 動詞 (Verb) + 補語 (Complement)

THE BUILDING WAS DESIGNED BY ME. 

=I DESIGNED THE BUILDING.

=I (SUBJECT) DESIGNED (VERB) THE BUILDING (COMPLEMENT)
