如果帶有單位詞，則由單位詞的單、復數形式決定動詞的單、復數形式。 例如：one pair of scissors isn\'t enough.
14.以-s結尾的地理名稱
某些以-s結尾的地理名稱，如果是國名，如the united states, the united nations, the netherlands等，盡管帶有復數詞尾，但系單一政治實體，故作單數用。但若不是國名，而是群島、山脈、海峽、瀑布等地理名稱、通常作復數用。例如：
the west indies, apart from the bahamas, are commonly divided into two parts. the himalayas（喜馬拉雅山脈) have a magnificent variety of plant and animal life.
the straits of gibraltar have not lost their strategic importance.
15. 英語中還有一些以-s結尾的名詞，如:
arms(武器), clothes(衣服), contents(內容，目錄)，fireworks(煙火), goods(貨物), minutes(記錄), morals(道德，品行), remains(遺體), stairs(樓梯), suburbs (郊區), thanks(謝意), wages(工資)等，通常作復數。
16.凡是由-ings結尾的名詞，如: clippings (剪下來的東西), diggings (掘出的東西), earnings (收入), filings (銼屑), lodgings (租住的房屋), surroundings (環境), sweepings (掃攏的垃圾) 等, 通常作復數用。例如：
the clippings of the hedges are usually burnt.
the sweepings of the godown(倉庫) have been disposed of.
17. 還有一些以-s接的單、復數同形的名詞，如: headquarters(總部), means(方法、手段), series(系列), species(種類), works(工廠)等，隨后動詞的單、復數形式取決于這些名稱是作單數，還是用作復數。例如：
a headquarters was set up to direct the operation (指揮作戰).
their headquarters are in paris.
the only means to achieve success is to appeal to arms (訴諸武力).
18. remains用于\"遺體\"意義時，隨后的動詞通常作復數：
his remains lie in the churchyard.
the martyr\'s remains were buried at the foot of the hill.
但作\"遺跡\"或\"剩余物\"解釋時，可作復數或單數用：
here is the remains of a temple.
the remains of the meal were/was fed to the dog.
19. 如果作主語的名詞詞組由“分數(或百分數)+of-詞組”構成，其動詞形式依of-詞組中名詞類別而定。例如：
two thirds of the swampland(沼澤地) _____ (have) been reclaimed(開墾).
over sixty per cent of the city ____ (be) destroyed in the war.
thirty-five per cent of the doctors ______ (be) women.
20. 如果主語是all of ...,some of ...,none of ...,half of ...,most of ...等表示非確定數量的名詞詞組，其后的動詞形式依of-詞組中的名詞類別而定。例如：
most of the money _____ recovered by deputy player.
most of the members ______ there.
all of the cargo ______ lost.
all of the crew ______ saved.
21.兩數相減或相除，動詞用單數；兩數相加或相乘，動詞可用單數，也可用復數。例如：
forty minus fifteen (40-15) leaves twenty-five.
forty divided by eight (40/8) is five.
