Question

( C )1. Don’t you have anything _____? (A)to open the box (B) which to open the box (C) to open the box with (D) which could open the box with (C ) 2. One’s capacity to live a full, rich life depends on good health and the mental faculty _____ clearly. (A)think...

Answer 1

(C)1. Don't you have anything _____?
(A)to open the box (B) which to open the box
(C) to open the box with (D) which could open the box with
此句若用(B)(D)代入指你沒有任何可以打開盒子的東西嗎?
which必須引導一個子句(B)(D)缺主詞
此句的主動詞為have，因此後面必須用不定詞，至於為何要加介係詞with：如... can open the box with something.必須用到介係詞，因此我們不可省略，此外anything是代名...

(C ) 2. One's capacity to live a full, rich life depends on good health and the mental faculty _____ clearly.
(A)think (B) thinking (C) to think (D) which to think
我們可以先消去(A)及(D)因為which必須引導子句，主動詞為depend... on因次think不可用原形動詞
至於為何要選(C)因為要做到此主詞One's capacity to live a full的先決條件是健康的身體及心理上名淨的機能（此兩種為目的，因此選to think）
觀念：不定詞表目的，計畫，意願。動名詞表經驗，已知的事
( B ) 3. Today, we can have our computers _____ at the fingerprints of people to identify them.
(A)to look (B) look (C) looked (D) looking
首先我們必須來了解have的用法：1.have+VR(主動)
2.have+p.p.(被動)此句很顯然是主動句，因此用原行動詞look
