Allot, allocate和distribute三个词都可做“分配”讲。Allot往往带有“任意性”，不包含“平均”或“公平”的意思，如：
One-child families are allotted the same amount of housing land and private plot as 2-child families.
He allots himself an hour a day for exercises.
We have been allotted 500 sq. m. for the exhibition.
Allocate常与表“金钱”、“财产”、“领土”、“权力”这类词连用，有“给予某人/集团专用”的意思：
the districts of Czechoslovakia allocated to Germany by the Munich Agreement.
The municipality has allocated a sum of money for the construction of the bridge.
One-child urban families are allocated the same housing space as 2-child families...
Take the system of "to each according to his work" as the main method of allocating income while complementing it with other forms of distribution.
... the central government...decided to allocate an investment of 240 million yuan which was placed under the company''s control
Management, administration, and allocation of labor force were highly centralized under the commune system.
Distribute基本的意思是“将某物分成若干部分后分发给若干人”，如：

...land owned by landlords were taken over and redistributed to 300 million peasants
The fund has been distributed in the best interests of those in need of relief.

Distribute, allot, allocate三个词都可以和“一笔款”连用，但distribute表示分配给“若干人”，而allot和allocate还可表示分配“给某个人专用”。
Characteristic, feature:
Characteristic和feature都有“特色”的意思，但characteristic基本的意思是“特征”，指恒定的、使某人或物有别于其他的人或物的属性和特质，如：
a characteristic of Western/Chinese civilization
women''s physiological characteristics

Feature的意思是“特色”或“特点”；feature不表示属性或特质，而是指某物（如脸面、景色、物体、性格）的一部分，因其外形或重要性突出而引人注目，如：
the geographical features of the region
Her dancing eyes are her most attractive features.
