Answer 1

A

不定式“to stand + 介詞”作定語修飾a tall box,其中被修飾詞在邏輯意義上是不及物動(dòng)詞，只有加上吊尾介詞，句子意思才完整。吊尾介詞往往由于受到漢語的影響而缺少，吊尾介詞使用的場(chǎng)合有：
（1）定語從句中，先行詞被一個(gè)不及物動(dòng)詞所修飾，不及物動(dòng)詞后要接介詞，先行詞被“動(dòng)詞 + 介詞”組成的短語動(dòng)詞所修飾，介詞常在句尾。
He is the man I just spoke to.
(2)what、whose、who、whatever等引導(dǎo)的賓語從句，賓語從句出現(xiàn)吊尾介詞。
I can’t imagine what it is like.
(3) 強(qiáng)調(diào)句型，特殊疑問句中由于被強(qiáng)調(diào)部分和疑問詞位置變更，常出現(xiàn)吊尾介詞。
It was the poor boy that we gave the books to.
What for? Where to? Who with?
(4)不及物動(dòng)詞的不定式修飾表“涉及對(duì)象、場(chǎng)合、工具、方式、材料”等意義的名詞時(shí)常帶吊尾介詞。
a room to live in, a bench to sit on
There is nothing to worry about.
She is a good girl to work with.
(5)某些形容詞后接不定式或“動(dòng)詞 + 介詞”型短語，動(dòng)詞的不定式形式表“反射”，常用吊尾介詞。
