什么時候介詞不能放在句末
這個問題一般在丁聰里面碰到的比較多
(1) 當定語從句中含有介詞，介詞放在句末時，who,that,which可省略，但介詞在關系代詞前時，只能用“介詞+which/whom”結構。
例如：This is the house in which we lived last year.
這是我們去年居住的房子。
Please tell me from whom you borrowed the English novel.
請告訴我你從誰那借的這本英文小說。
(2) 含有介詞的固定動詞詞組中，介詞不可前置，只能放在原來的位置上。 例如：This is the person whom you are looking for.
這就是你要找的那個人。
(3)that 作介詞的賓語時，介詞不能放它的前面，只能放在從句中動詞的后面。
例如：The city that she lives in is very far away.
什么時候句末介詞不能省
改一下就對：Many supermarkets offer people the greatest shoes
to choose .(choose the greatest shoes)(choose from a great many shoes)
不及物動詞不定式作名詞后置修飾語，并與名詞存在動賓或主謂關系時，必須加上一個結構或含義上所需要的 介詞，如：
We bought a flat to live in.
The children have got some toys to play with.
有時不及物動詞不定式與被修飾的名詞存在介詞+賓語的關系，這時介詞也必須補上，如：
a broom to clean it with/a file to keep sth,in/
a desk to put the books on/a knife to cut *
但修飾place,day,way,time等詞時，在現代英語中可以省略介詞。試比較：
find a house to live.
Let's find a good place to live(in)/to sit(on)/to go(to).
后place之后跟一個關系分句時，分句中的介詞通常不能省略：
That's the place which she works in.
要注意：
"Who was the first one to arrive" 中的不定式與被修飾成分之間構成了主謂關系，且“到達”無對象，故用不及物動詞（arrive或get）來表達，而不用arrive at/reach.
句末的介詞from可否省

(choose the greatest shoes)(choose from a great many shoes) 不及物動詞不定式作名詞后置修飾語，并與名詞存在動賓或主謂關系時，必須加上一個結構或含義上所需要的 介詞，如： We bought a flat to live in。 The children have got some toys to play with。
